The reception program 125a is, for example, a program for causing the CPU 121 to realize a function of receiving first content data including audio data and video data and second content data belonging to the same series as the first content data. It is.
Specifically, when the key input unit 1 performs an operation to instruct recording of a program, the CPU 121 tunes the tuner 2 to a specific frequency band and receives a broadcast signal. Further, when recording of a series-type program is reserved, the broadcast signal of the program is received from the broadcast start time of the reserved program to the broadcast reception time. Furthermore, TS packets (content data, first content data, and second content data) of the recorded program are acquired from the received TS and output to the encoder unit 3.
The CPU 121 functions as a receiving unit together with the tuner 2 by executing the receiving program 125a.

The recording program 125b is a program for realizing a function of recording the first content data and the second content data received by the execution of the reception program 125a.
Specifically, the CPU 121 encodes the first content data or the second content data extracted by the tuner 2 into a file format that can be recorded on the DVD 61 by the encoder unit 3, and the data processor 5 performs error correction coding. , 8-16 modulation or the like is performed, and the DVD drive unit 6 records the data on the DVD 61. The CPU 121 records programs belonging to the same series in association with each other.
The CPU 121 functions as a recording unit together with the DVD drive unit 6 by executing the recording program 125b.

The reproduction program 125c, for example, causes the CPU 121 to reproduce the first content data and the second content data recorded by the execution of the recording program 125b, and to output audio based on the audio data from the audio output unit 300b. This is a program for realizing a function of displaying video based on video data on the display unit 300a.
Specifically, when the key input unit 1 performs an operation for instructing reproduction of a program recorded on the DVD 61, the CPU 121 causes the DVD drive unit 6 to execute content data (first data) recorded on the DVD 61. Content data or second content data) is read out, subjected to 8-16 demodulation, error correction decoding, and the like, and sent to the decoder unit 7. Further, after the separation unit 71 separates the video stream, the audio stream, and the data stream, the video decoder 72, the audio decoder 73, and the data decoder 74 decode the streams, respectively, and the television receiver connected to the apparatus main body. The audio is output from the audio output unit 300b of the machine 300 and the video is displayed on the display unit 300a.
The CPU 121 functions as a playback unit by executing the playback program 125c.

For example, the marking program 125d is a program for causing the CPU 121 to realize a function of marking the sound output from the sound output unit 300b when the first content data is played back by executing the playback program 125c.
Specifically, the user decides every time at a predetermined timing (for example, at the same time or immediately before) when information (titles or characters of broadcast times) desired to be included in the title is provided by audio or video. Mark the melody and phrases used by the title creation key 1a. More specifically, when playing back the first content data, the user views the audio output from the audio output unit 300b of the television receiver 300 or the video displayed on the display unit 300a, and includes it in the title information. While the desired audio or video is being output, the title creation key 1a of the key input unit 1 is pressed. Alternatively, when the user reproduces the first content data, the user views the audio output from the audio output unit 300b of the television receiver 300 or the video displayed on the display unit 300a, and the audio or video that the user wants to include in the title information. The title creation key 1a of the key input unit 1 is pressed before a predetermined time (for example, one second before) is output.
Then, based on the pressing of the title creation key 1a, the CPU 121 determines the voice output from the audio output unit 300b while the key is pressed as the marking voice.
The CPU 121 functions as a marking unit together with the title creation key 1a by executing the marking program 125d.

The storage program 125e, for example, realizes a function of storing a predetermined reproduction position at which the sound stored in the reproduction position storage unit 124 is reproduced in the CPU 121 by executing the marking program 125d in the first content data. It is a program to make it.
Specifically, when the voice output from the voice output unit 300b is determined as the marking voice while the title creation key 1a is pressed by executing the marking program 125d, the CPU 121 determines the predetermined marking voice. Determine the playback position.
The predetermined reproduction position is indicated by, for example, an elapsed time from the start of program broadcasting. In addition, the predetermined reproduction position includes information on a key pressing time. When the playback position is determined, the CPU 121 causes the playback position storage unit 124 to store information related to the playback position (for example, elapsed time data from the start of broadcast of the program) together with identification information of the program / series.
The CPU 121 functions as a storage unit together with the reproduction position storage unit 124 by executing the storage program 125e.

The acquisition program 125f, for example, gives the CPU 121 the audio data or audio data of a predetermined reproduction position based on the audio data marked by execution of the marking program 125d in the first content data or the reproduction position of the audio data. It is a program for realizing the function of acquiring audio data or video data included in the second content data based on a predetermined reproduction position stored by execution of the storage program 125e.
The CPU 121 functions as an acquisition unit together with the DVD drive unit 6 and the analysis unit 4 by executing the acquisition program 125f.

The creation program 125g is, for example, the title information and the second content of the first content data recorded by the execution of the recording program 125b based on the audio data or the video data acquired by the CPU 121 by the execution of the acquisition program 125f. This is a program for realizing the function of creating data title information. The creation program 125g converts voice data acquired by the execution of the acquisition program 125f into character data, and creates title information including at least a part of characters based on the character data, or is acquired by execution of the acquisition program 125f. Character data included in the video data is acquired, and title information including at least a part of characters based on the character data is created.
The CPU 121 functions as a creation unit together with the title information creation unit 10 by executing the creation program 125g.

The title information creation method is selected in advance by the user on the menu screen illustrated in FIG. In the menu screen of FIG. 2, for example, four title creation methods can be selected.
For example, a first method is to create title information by converting text marked with the title creation key 1a into text.
The second method is to create title information by text-converting characters in the video displayed on the display unit 300a during playback of audio marked with the title creation key 1a.
A third method is to create title information by converting text to be played back after a predetermined time (for example, after 1 to 10 seconds) of the voice marked with the title creation key 1a.
Fourth, a method of creating title information by converting text in video displayed on the display unit 300a after a predetermined time (for example, 1 to 3 seconds later) of the voice marked with the title creation key 1a. is there.
In the menu screen of FIG. 2, the user can freely set the number of seconds after the voice marked with the title creation key 1a to obtain the audio data / video data, the time width, and the like.

  In the execution of the acquisition program 125f, the CPU 121 obtains title information from the first content data and the second content data on the menu screen illustrated in FIG. 2 based on the title information creation method selected in advance by the user. create.

First, a method for creating title information by converting text marked with the title creation key 1a into text from the first content data and the second content data will be described.
For example, when the user presses the title creation key 1 a during playback of the first content data, the CPU 121 stores the playback position of the audio played back while the title creation key 1 a is pressed in the playback position storage unit 124. Let Then, the marked audio data in the first content data (for example, “Tous and Goon”) is acquired from the DVD 61.
When the second content data belonging to the same series as the first content data is received by the tuner 2, the CPU 121 stores the second content data from the second content data in the reproduction position storage unit 124. Audio data at the playback position (for example, “Akahana no J * s”) is acquired.
Since the second content data is a program belonging to the same series as the first content data, the audio at the reproduction position stored in the reproduction position storage unit 124 acquired from the second content data is the first content data. There is a high possibility that it is the same type of audio (for example, an announcement of a subtitle) as the audio marked during playback of the content data, and it is desired to be included in the title information in the same way as the audio marked during the playback of the first content data It is highly likely that the voice is in line with the user's intention.

Secondly, from the first content data and the second content data, during playback of the audio marked with the title creation key 1a, the text in the video displayed on the display unit 300a is converted to text and title information is created. The case where it does is demonstrated.
For example, when the user presses the title creation key 1 a during playback of the first content data, the CPU 121 stores the playback position of the audio played back while the title creation key 1 a is pressed in the playback position storage unit 124. Let Then, the video data of the video (for example, FIG. 3) displayed on the display unit 300a during the reproduction of the marked audio data in the first content data is acquired from the DVD 61.
When the second content data belonging to the same series as the first content data is received by the tuner 2, the CPU 121 stores the second content data from the second content data in the reproduction position storage unit 124. During the reproduction of the audio data at the reproduction position, the image data of the image (for example, FIG. 4) displayed on the display unit 300a is acquired.
Since the second content data is a program belonging to the same series as the first content data, the video output from the second content data and output together with the audio at the reproduction position stored in the reproduction position storage unit 124 Is likely to be a video in line with the user's intention including the text (eg, subtitle) to be included in the title information, similar to the video output together with the audio marked at the time of reproduction of the first content data. it is conceivable that.

Third, a case will be described in which title information is created by text-converting audio reproduced after a predetermined time of audio marked with the title creation key 1a from the first content data and the second content data.
For example, when the user presses the title creation key 1 a during playback of the first content data, the CPU 121 stores the playback position of the audio played back while the title creation key 1 a is pressed in the playback position storage unit 124. Let Then, a sound (for example, “appearing friends: To * s, Go * n”) that is reproduced after a predetermined time (for example, 1 to 10 seconds) after the marked voice in the first content data. Audio data is acquired from the DVD 61.
When the second content data belonging to the same series as the first content data is received by the tuner 2, the CPU 121 stores the second content data from the second content data in the reproduction position storage unit 124. Voices that are played after a predetermined time (for example, 1 to 10 seconds) after the playback position (for example, “Appearing friends: J * S, D *, B *, B *, B *, T ) Audio data.
Since the second content data is a program belonging to the same series as the first content data, the predetermined reproduction based on the sound at the reproduction position stored in the reproduction position storage unit 124 acquired from the second content data. The sound at the position (after a predetermined time) is the same type of sound (for example, a character) that is reproduced after a predetermined time (for example, after 1 to 10 seconds) of the sound marked when the first content data is reproduced. It is considered that there is a high possibility that the sound is in line with the user's intention to be included in the title information in the same manner as the sound acquired at the time of reproducing the first content data.

Fourth, from the first content data and the second content data, the title information is created by converting text in the video displayed on the display unit 300a after a predetermined time of the voice marked by the title creation key 1a to text. How to do will be described.
For example, when the user presses the title creation key 1 a during playback of the first content data, the CPU 121 stores the playback position of the audio played back while the title creation key 1 a is pressed in the playback position storage unit 124. Let Then, a video (for example, FIG. 5) displayed on the display unit 300a after a predetermined time (for example, after 1 to 3 seconds) of the marked audio in the first content data is acquired from the DVD 61.
When the second content data belonging to the same series as the first content data is received by the tuner 2, the CPU 121 stores the second content data from the second content data in the reproduction position storage unit 124. Video data of a video (for example, FIG. 6) displayed on the display unit 300a after a predetermined time (for example, 1 to 3 seconds) after the playback position is acquired.
Since the second content data is a program belonging to the same series as the first content data, the second content data is displayed after a predetermined time of the audio at the reproduction position stored in the reproduction position storage unit 124 acquired from the second content data. The video displayed on the unit 300a is a video in line with the user's intention including the text (for example, the name of a character) to be included in the title information, like the video acquired when the first content data is reproduced. The possibility is considered high.

Next, in the execution of the creation program 125g, a case where the acquired voice is converted into text and title information including the converted text is created will be specifically described.
When the CPU 121 acquires audio data from the first content data or the second content data, the CPU 121 outputs the acquired audio data to the audio recognizing unit 9, and the audio data is converted into text data (for example, “To * s and Go *”). And “Character names: To * s and Go * n”). Then, the converted text data is output to the title information creation unit 10, and title information is created based on the text data.
In the title information creation unit 10, for example, a series name (for example, “Tous and Tokamachi” etc.) included in the additional information (program arrangement information) transmitted together with the content data, and text converted from the audio data Data (for example, “To * s and Go * n”, “Character name: To * s and Go * n”, etc.) and the title information (for example, “To * s and Goto Toss * And “Go * n”, “To * s and friends” (Character name: To * s and Go * n ”, etc.).
Also, for example, text data obtained by converting audio data without including the series name included in the additional information transmitted together with the content data in the title information is used as it is in the title information (for example, “Toss and Goon”). , “Character names: To * s, Go * n”, etc.).
When the title information is created by the title information creation unit 10, the CPU 121 outputs the title information to the DVD drive unit 6 through the data processor 5, and records it on the DVD 61 in association with the first content data or the second content data. .

Further, a case will be specifically described in which, in the execution of the creation program 125g, characters included in the acquired video data are converted into text, and title information including the converted text is created.
When the CPU 121 acquires the video data from the first content data or the second content data, the CPU 121 outputs the captured video data to the character recognition unit 8 and converts the characters included in the video data into text data (for example, “ ”And“ Go * n ”,“ Character name: To * s and Go * n ”, etc.). Then, the converted text data is output to the title information creation unit 10, and title information is created based on the text data.
In the title information creation unit 10, for example, a series name (for example, “Tous and Tokamachi” etc.) included in the additional information (program arrangement information) transmitted together with the content data, and the text extracted from the video data Data (for example, “To * s and Go * on”, “Character name: To * s and Go * n”, etc.) and the title information (for example, “To * s and Goto Tos * And “Go * n”, “To * s and friends” (Character name: To * s and Go * n ”, etc.).
In addition, for example, the title name (for example, “To * s and Go * n” is used as it is, without including the series name included in the additional information transmitted together with the content data in the title information, and the text data extracted from the video data. , “Character names: To * s, Go * n”, etc.).
When the title information is created by the title information creation unit 10, the CPU 121 outputs the title information to the DVD drive unit 6 through the data processor 5, and records it on the DVD 61 in association with the first content data or the second content data. .

  Note that the title information is created by distinguishing the types of subtitles, characters, etc. obtained from the series name, audio data or video data extracted from the additional information, depending on the display format (display position, display color, text), etc. (For example, “Series name: To * s and Tokasato subtitles: Akahana's J * s Characters: J * S, ○ Cook, ○ Lu, ○ Non, ○ Co, Tore *)”) .

7 and 8 show title information displayed on the display unit 300a of the television receiver 300 when title information including characters included in audio data or video data acquired based on the marked audio is created. It is a figure which illustrates the list of.
In FIG. 7, a series name (for example, “Toss and Tokamachi”) included in additional information (program arrangement information) transmitted together with content data, and text data extracted from audio data or video data are shown. The parts (for example, “To * s and Go * n”, “Akahana no J * s”) are combined into the title information.
Further, in FIG. 8, the series name included in the additional information (program arrangement information) transmitted together with the content data is not included in the title information, and text data extracted from audio data or video data (for example, “TO And Go * n Characters: To * s, Go * n "," Akahana no J * s Characters: J * s, * Cook, * Le, * N, * Ko, Tore * ") However, the title information is used as it is.

According to the DVD recorder 100 in the first embodiment described above, the first content data including the audio data and the video data and the second content belonging to the same series as the first content data are executed by executing the reception program 125a. When the data is received, the first content data and the second content data received by executing the receiving program 125a are recorded by executing the recording program 125b, and recorded by executing the recording program 125b by executing the reproducing program 125c. The reproduced first content data and second content data are reproduced, audio based on the audio data is output from the audio output unit 300b, and video based on the video data is displayed on the display unit 300a, and the marking program 125d The fruit Thus, when the first content data is reproduced by executing the reproduction program 125c, the sound output from the audio output unit 300b is marked, and by executing the storage program 125e, the marking is performed by the marking program 125d in the first content data. A predetermined reproduction position at which the reproduced audio is reproduced is stored, and by executing the acquisition program 125f, the audio data of the audio marked by the marking program 125d or the reproduction position of the audio data in the first content data is determined. The audio data or video data at the reproduction position is acquired, and the first data belonging to the same series as the first content data (content data) based on the predetermined reproduction position stored by the execution of the storage program 125e. Audio data or video data included in the content data is acquired, and the first program recorded by the recording program 125b based on the audio data or video data acquired by executing the acquisition program 125f by executing the creation program 125g. Title information of content data and title information of second content data are created. Also, by executing the creation program 125g, the audio data acquired by executing the acquisition program 125f is converted into character data, and title information including at least a part of characters based on the character data is generated or executed by the execution of the acquisition program 125f. Character data included in the acquired video data is acquired, and title information including at least a part of characters based on the character data is created.
Therefore, if audio is marked during reproduction of content data, title information is created based on audio data or video data based on the audio. Therefore, it is possible to create a title of the recorded content more in line with the user's intention by an easy operation using audio data or video data included in the content data.
In addition, even if the user himself / herself does not input the title information, the title information desired by the user can be created only by marking the desired voice, which is very convenient for the user.
Furthermore, even information that is not included in the additional information can be included in the title information, so that title information that is more desirable for the user can be created.

Further, when the title information is created by marking the sound during reproduction of the first content data, the second content data belonging to the same series as the first content data is marked in the first content data. Title information is created based on the video at the same playback position as the reproduced audio.
That is, even if the marking operation is not performed for each of the second content data belonging to the same series as the first content data, if the audio is marked during reproduction of the first content data, the second content data belonging to the same series The title information corresponding to the audio or video of each of the two content data is automatically created. Therefore, it is not necessary to create title information for each of the second content data belonging to the same series as the first content data, and the second content data does not need to be marked with the audio of the second content data. Appropriate title information corresponding to each content data is created, which is more convenient for the user.

  Also, by executing the creation program 125g, the audio data acquired by executing the acquisition program 125f is converted into character data, and title information including at least a part of characters based on the character data is generated. Mark the voice that contains the voice you want to include, or mark the voice around the specified time including the voice you want to include in the title information, create the title information that is more desirable for the user, including the desired character information in the title information can do.

  Further, by executing the creation program 125g, character data included in the video data acquired by executing the acquisition program 125f is acquired, and title information including at least a part of characters based on the character data is generated. Mark the audio to be played while the video containing the characters you want to include in the information is displayed, or mark the audio to be played before or after the predetermined time of the video containing the characters you want to include in the title information It is possible to create more desirable title information for the user by including the character information in the title information.

(Embodiment 2)
Next, Embodiment 2 of the present invention will be described in detail with reference to the drawings.
The recording / reproducing apparatus of the second embodiment will be described as being a DVD recorder, for example, as in the first embodiment.
In addition, about the structure similar to Embodiment 1, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

First, the main configuration of the DVD recorder 200 according to the second embodiment will be described with reference to FIG.
For example, the DVD recorder 200 receives a broadcast signal transmitted from the key input unit 1 and the broadcast station, selects a broadcast signal of a predetermined broadcast channel from the broadcast signal, and selects content data (first The content data and the second content data), the encoder 2 that performs a predetermined compression process on the content data input from the tuner 2, and the content data input from the tuner 2 to analyze the audio data Alternatively, the analysis unit 13 that acquires the video data controls the input / output of content data, supplies the content data input from the encoder unit 3 to the DVD drive unit 6, and decodes the content data captured from the DVD drive unit 6 Recording of broadcast program data to the data processor 5 and DVD 61 supplied to the unit 7 And a DVD drive unit 6 that performs reproduction, a decoder unit 7 that performs predetermined expansion processing on broadcast program data output from the DVD drive unit 6, a character recognition unit 8 that recognizes characters included in video data, and voice recognition Then, the speech recognition unit 9 converts the text data into text data, the text data input from the character recognition unit 8, the text data input from the speech recognition unit 9, and the additional information input from the video decoder 72 (program sequence information (SI: Service information)), a title information creation unit 10 that creates title information, a mixing unit 11 that synthesizes OSD data and the like into a video signal, a control unit 14 that controls the entire DVD recorder 200, and the like. .

The key input unit 1 is, for example, a remote controller that remotely operates the device main body, and generates a remote control signal based on pressing of various keys and outputs the remote control signal to the control unit 14 of the device main body.
The key input unit 1 is provided with a title creation key 1a for marking a desired reproduction sound and instructing creation of a title when reproducing the first content data. When the title creation key 1a is operated, a marking program 125d, a storage program 143a, an acquisition program 143b, and a creation program 143c, which will be described later, are executed, and predetermined reproduction based on the marked sound or the reproduction position of the marked sound is performed. The title information of the first content data based on the audio or video at the position is created.

When title information of the first content data is created by operating the title creation key 1a, title information of the second content data belonging to the same series as the first content data is created.
In particular, in the second embodiment, the reproduction position of the marked audio in the first content data is not stored as in the first embodiment, but the marked audio data itself in the first content data is stored. Remembered. Then, audio data whose similarity to the stored audio data is greater than or equal to a predetermined threshold is detected from the second content data, the reproduction position of the detected audio data is detected, and the audio data at the reproduction position is detected. Alternatively, the title information of the second content data is created based on audio data or video data at a predetermined reproduction position based on the detected reproduction position.

  The analysis unit 13 analyzes the TS as the second content data input from the tuner 2, and the audio data marked in the first content data or the audio data marked in the first content data Audio data or video data at a predetermined reproduction position based on the reproduction position is acquired.

  The control unit 14 includes a CPU (Central Processing Unit) 141, a time measuring unit 122 that measures the current time, a RAM (Random Access Memory) 123, a marking voice storage unit 142, a ROM (Read Only Memory) 143, and the like. Yes.

  The CPU 141 executes various programs stored in the ROM 143 in accordance with input signals input from the respective units, and outputs output signals to the respective units based on the execution programs, so that the entire operation of the DVD recorder 200 is performed. Take overall control.

The RAM 123 stores, for example, processing results generated when various programs are executed by the CPU 141, input data, and the like.
The marking voice storage unit 142 is configured by an EPROM (Erasable Programmable ROM) or the like, and stores the voice marked by the operation of the title creation key 1a in the execution of the storage program 143a described later for each program (series).

  The ROM 143 has a program storage area composed of a non-volatile memory. Specifically, the reception program 125a, recording program 125b, reproduction program 125c, marking program 125d, storage program 143a, acquisition program 143b, creation program 143c, etc. Is remembered.

The storage program 143a is, for example, a program for causing the CPU 141 to realize a function of storing audio data marked by executing the marking program 125d in the first content data (content data).
Specifically, when the sound output from the audio output unit 300b is determined as the marking sound when the title creation key 1a is pressed by the execution of the marking program 125d, the CPU 141 determines the marking sound as the program. The information is stored in the marking voice storage unit 142 together with the series identification information.
The CPU 141 functions as a storage unit together with the marking voice storage unit 142 by executing the storage program 143a.

The acquisition program 143b is, for example, a predetermined content based on the voice data stored in the marking voice storage unit 142 or the reproduction position of the voice data marked by the CPU 141 by the execution of the marking program 125d in the first content data. The audio data or the video data at the reproduction position is acquired, and the audio data stored by executing the storage program 143a is reproduced from the second content data belonging to the same series as the first content data (content data). It is a program for realizing a function of detecting a playback position and acquiring audio data or audio data included in the second content data based on the detected playback position.
The CPU 141 functions as an acquisition unit together with the DVD drive unit 6 and the analysis unit 13 by executing the acquisition program 143b.

The creation program 143c, for example, sends the title information of the first content data (content data) recorded by the execution of the recording program 125b to the CPU 141 based on the audio data or the video data acquired by the execution of the acquisition program 143b. This is a program for realizing the function of creating the title information of the second content data based on the audio data or the video data acquired by executing the acquisition program 143b.
The CPU 141 functions as a creation unit together with the title information creation unit 10 by executing the creation program 143c.

The method for creating the title information is selected in advance by the user on the menu screen illustrated in FIG. In the menu screen of FIG. 10, for example, three title creation methods can be selected.
For example, a first method is to create title information by converting text in a video displayed on the display unit 300a into text during playback of audio marked with the title creation key 1a.
Secondly, the title information is created by converting text to be played back after a predetermined time (for example, after 1 to 10 seconds) of the voice marked with the title creation key 1a.
Third, a method of creating title information by converting text in a video displayed on the display unit 300a after a predetermined time (for example, 1 to 3 seconds later) of the voice marked with the title creation key 1a. is there.
In the menu screen of FIG. 2, the user can freely set the number of seconds after the voice marked with the title creation key 1a to obtain the audio data / video data, the time width, and the like.

First, from the first content data and the second content data, the title information is created by converting text in the video displayed on the display unit 300a into text during playback of the audio marked with the title creation key 1a. The case where it does is demonstrated.
For example, when the user depresses the title creation key 1a during reproduction of the first content data, the CPU 141 stores the audio reproduced while the title creation key 1a is depressed in the marking audio storage unit 142. Then, the video data of the video (for example, FIG. 3) displayed on the display unit 300a during the reproduction of the marked audio data in the first content data is acquired from the DVD 61.
When the second content data belonging to the same series as the first content data is received by the tuner 2, the CPU 141 stores the second content data from the second content data in the marking sound storage unit 142. Audio data whose similarity to the audio data is equal to or greater than a predetermined threshold is detected, and video data of the video (for example, FIG. 4) displayed on the display unit 300a is acquired during the reproduction of the audio data.
Since the second content data is a program belonging to the same series as the first content data, the video output together with the audio stored in the marking audio storage unit 142 acquired from the second content data is the first content data. Like the video output together with the audio marked when reproducing the content data of 1, the video is likely to be in accordance with the user's intention including the text (eg, subtitle) to be included in the title information. .

Secondly, a case will be described in which title information is created by text-converting audio reproduced after a predetermined time of audio marked by the title creation key 1a from the first content data and the second content data.
For example, when the user depresses the title creation key 1a during reproduction of the first content data, the CPU 141 stores the audio reproduced while the title creation key 1a is depressed in the marking audio storage unit 142. Then, a sound (for example, “appearing friends: To * s, Go * n”) that is reproduced after a predetermined time (for example, 1 to 10 seconds) after the marked voice in the first content data. Audio data is acquired from the DVD 61.
When the second content data belonging to the same series as the first content data is received by the tuner 2, the CPU 141 stores the second content data from the second content data in the marking sound storage unit 142. Voice data is detected and played back after a predetermined time (for example, 1 to 10 seconds) after the detected voice data (for example, “Appearing friends: J * S, D *, B *, V ○, Bo ○, Train ○-”).
Since the second content data is a program that belongs to the same series as the first content data, a predetermined reproduction position (predetermined based on the sound acquired from the second content data and stored in the marking sound storage unit 142). The audio after the time is the same type of audio (for example, an announcement of a character, etc.) that is reproduced after a predetermined time (for example, 1 to 10 seconds) after the audio marked at the time of reproduction of the first content data. ), And it is highly likely that the sound is in line with the user's intention to be included in the title information, similar to the sound acquired when the first content data is reproduced.

Third, from the first content data and the second content data, the title information is created by converting text in the video displayed on the display unit 300a after a predetermined time of the voice marked by the title creation key 1a to text. How to do will be described.
For example, when the user depresses the title creation key 1a during reproduction of the first content data, the CPU 141 stores the audio reproduced while the title creation key 1a is depressed in the marking audio storage unit 142. Then, a video (for example, FIG. 5) displayed on the display unit 300a after a predetermined time (for example, after 1 to 3 seconds) of the marked audio in the first content data is acquired from the DVD 61.
When the second content data belonging to the same series as the first content data is received by the tuner 2, the CPU 141 stores the second content data from the second content data in the marking sound storage unit 142. Video data of a video (for example, FIG. 6) displayed on the display unit 300a after a predetermined time (for example, 1 to 3 seconds) after the voice is acquired.
Since the second content data is a program belonging to the same series as the first content data, after a predetermined time (for example, 1) of the audio stored in the marking audio storage unit 142 acquired from the second content data The video displayed on the display unit 300a after 3 seconds) is similar to the video acquired when the first content data is reproduced, and includes the text (for example, the name of a character) to be included in the title information. It is likely that the video is in line with the intention.

According to the DVD recorder 200 in the second embodiment described above, the first content data including the audio data and the video data and the second content belonging to the same series as the first content data are executed by executing the reception program 125a. When the data is received, the first content data and the second content data received by executing the receiving program 125a are recorded by executing the recording program 125b, and recorded by executing the recording program 125b by executing the reproducing program 125c. The reproduced first content data and second content data are reproduced, audio based on the audio data is output from the audio output unit 300b, and video based on the video data is displayed on the display unit 300a, and the marking program 125d The fruit Thus, when the first content data is reproduced by executing the reproduction program 125c, the audio output from the audio output unit 300b is marked, and by executing the storage program 143a, the first content data is marked by the marking program 125d. Recorded in the first content data by the execution of the acquisition program 143b, or audio data or video data at a predetermined reproduction position based on the reproduction position of the audio data in the first content data Is acquired, and the reproduction position where the audio data stored by the execution of the storage program 143a is reproduced is detected from the second content data belonging to the same series as the first content data, and is detected. Based on the reproduced position, audio data or video data included in the second content data is acquired, and by executing the creation program 143c, based on the audio data or video data acquired by executing the acquisition program 143b, Title information of the first content data and title information of the second content data recorded by the recording program 125b are created. Also, by executing the creation program 143c, the audio data acquired by executing the acquisition program 143b is converted into character data, and title information including at least a part of characters based on the character data is generated or executed by the execution of the acquisition program 143b. Character data included in the acquired video data is acquired, and title information including at least a part of characters based on the character data is created.
That is, when the audio to be reproduced is marked during the reproduction of the content data, title information is created based on the audio data of the audio or the audio data or video data at a predetermined reproduction position based on the reproduction position of the audio data. It becomes. Therefore, in the DVD recorder 200 (recording / playback apparatus), it is possible to create a title of the recorded content more in line with the user's intention by an easy operation using audio data or audio data included in the content data.
In addition, even if the user himself / herself does not input the title information, the title information desired by the user can be created only by marking the desired voice, which is very convenient for the user.
Furthermore, even information that is not included in the additional information can be included in the title information, so that title information that is more desirable for the user can be created.

Further, when the title information is created by marking the sound that is played back when the first content data is played back, the second content data belonging to the same series as the first content data is the first content data. A reproduction position where the voice marked in the data is reproduced is detected, and title information is created based on the voice of the detected reproduction position.
In other words, each of the second content data belonging to the same series can be marked by marking the audio reproduced during the reproduction of the first content data without performing the marking operation for each of the content data belonging to the same series. Title information corresponding to the audio data or video data is automatically created. Therefore, it is not necessary to create the title information of the second content data, and appropriate title information corresponding to each of the second content data is created without marking the voice of the second content data. This is more convenient for the user.
In addition, even when the audio marked in the first content data is reproduced at a different reproduction position in the second content data, the second content data is used based on the audio marked in the first content data. Since audio data or video data is detected and title information is created, title information desirable for the user can be created more reliably.

  Also, by executing the creation program 143c, the audio data acquired by executing the acquisition program 143b is converted into character data, and title information including at least a part of characters based on the character data is generated. Mark the voice that contains the voice you want to include, or mark the voice around the specified time including the voice you want to include in the title information, create the title information that is more desirable for the user, including the desired character information in the title information can do.

  Further, by executing the creation program 143c, character data included in the video data acquired by executing the acquisition program 143b is acquired, and title information including at least a part of characters based on the character data is generated. Mark the audio to be played while the video containing the characters you want to include in the information is displayed, or mark the audio to be played before or after the predetermined time of the video containing the characters you want to include in the title information It is possible to create more desirable title information for the user by including the character information in the title information.

The present invention is not limited to the above embodiment, and various improvements and design changes may be made without departing from the spirit of the present invention.
For example, the title information created by the creating unit is not limited to that exemplified in the above embodiment. For example, only the title of the broadcast time may be used as title information, such as “To * s and Go * n”. Further, in addition to the title of the broadcast and the name of the character, information included in audio data, video data, and additional information, such as a simple synopsis, can be included in the title information.
Further, title information including a thumbnail image of video data acquired from the first content data or the second content data may be created.
In addition, there is provided a discriminating means for discriminating only necessary text such as a title and a character name from text data extracted from audio data or video data, and the creating means is only text determined to be necessary by the discriminating means. May be included in the title information.
Moreover, you may comprise so that several audio | voices can be marked per content data. Then, for example, the voice marked for the first time is determined to be the voice data including the subtitle, and the voice marked for the second time is determined to be the voice including the character name. Then, the title information may be created by distinguishing the type of sound such as the subtitle and the character name.
In addition, when marking the audio of the first content data, there may be provided means for allowing the user to specify the type of the marked audio (for example, title, subtitle, character name) and the like.
Further, when marking the voice of the first content data, there may be provided means capable of designating a voice section (for example, the second half part of the marked voice) included in the title information among the marked voice.
Further, the audio data or video data acquired from the second content data may be acquired from the DVD 61 after being once recorded on the DVD 61 instead of being acquired by the analysis unit 13 when the second content data is received. .
In the above-described embodiment, the title creation method for marking the audio reproduced during the output of the audio / video to be included in the title information, and the audio reproduced for a predetermined time before the audio / video included in the title information is output. Although only the method for creating a title to be marked has been described, a method for creating a title by marking audio after a predetermined time from which audio / video included in title information is output may be provided. Further, there may be provided means for allowing the user to freely set the number of seconds before the voice marked with the title creation key 1a to obtain the audio data / video data, and the time width thereof.
