DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0018]
FIG. 1 is a block diagram showing a configuration example of a hard disk recorder to which the present invention is applied.
[0019]
The tuner 1 receives a television signal from a terrestrial wave, a communication satellite, or a broadcast satellite, outputs the extracted video signal to the video signal processing circuit 3, and outputs the audio signal to the audio signal processing circuit 2. The tuner 1 also supplies the received video signal and audio signal to an MPEG (Moving Picture Expert Group) encoder / decoder / VRAM (Video Random Access Memory) 4. The MPEG encoder / decoder / VRAM 4 encodes the input signal by the MPEG method, and supplies the encoded signal to the storage 12 composed of a hard disk for recording.
[0020]
Further, the tuner 1 receives an EPG (Electrical Program Guide) related to a program (if metadata including information related to content indexes and segments is also included), supplies it to the storage 12, and stores it. In addition, when the signal received by the tuner 1 is recorded, the storage 12 also stores the recording start time, the length of the recording time, the received broadcast channel, the genre to which the program belongs, and the like.
[0021]
Note that the metadata includes an index and a segment. The index corresponds to a predetermined time of the content, and a comment and an icon regarding the content at the time are added. A segment corresponds to a predetermined period, such as a highlight scene, of the content, and a start time, an end time, a comment, an icon, and the like are added to the segment.
[0022]
When a story is constituted by an arbitrary number of segments, this story is also stored in the storage 12.
[0023]
Further, the MPEG encoder / decoder / VRAM 4 decodes the signal reproduced from the storage 12 by the MPEG method, writes the video data once in the built-in VRAM, reads it again from there, and outputs it to the video signal processing circuit 3. . The reproduced audio data is decoded and output to the audio signal processing circuit 2.
[0024]
The video signal processing circuit 3 performs predetermined processing on the input video signal, converts it to an analog signal, outputs it to the display 32, and displays it. The audio signal processing circuit 2 performs predetermined processing on the input audio signal, converts it to an analog signal, and outputs it to the speaker 31.
[0025]
In addition to video or audio content, the storage 12 also stores information data (for example, broadcast date and time, channel, etc.) when a video signal is recorded. The storage 12 further stores an OS (Operation System), application programs, data unique to the application programs, and the like.
[0026]
A non-volatile RAM (Random Access Memory) 11 stores unique ID information of this hard disk recorder, user ID information, area information where the user resides, and the like. A ROM (Read Only Memory) 10 stores a bootstrap module as a module for starting the OS, other programs, parameter data, and the like. In the RAM 9, a bootstrap module, an OS, an application program, and the like are expanded from the ROM 10 and the storage 12 as necessary, and are executed by a CPU (Central Processing Unit) 8.
[0027]
The data stored in the storage 12 can be recorded in the RAM 9 or the nonvolatile RAM 11, for example.
[0028]
When the user operates the keyboard 13 or the mouse 14 to input a predetermined command, the CPU 8 executes a process corresponding to this command. The clock 15 performs a time measuring operation and outputs time information.
[0029]
This hard disk recorder is provided with a remote control light receiving unit 7, and this remote control light receiving unit 7 receives an infrared signal generated by the light emitting unit 61 (FIG. 2) of the remote controller 21 in response to a user operation. A signal corresponding to the infrared signal is output to the CPU 8.
[0030]
When displaying a GUI (Graphical User Interface) screen for user operation (for example, a screen for selecting a video content to be reproduced from a list of displayed video content), the CPU 8 generates a GUI processing program. The image data displayed on the GUI is supplied to the MPEG encoder / decoder / VRAM 4 and output to the display 32 via the video signal processing circuit 3 for display.
[0031]
The modem 6 performs processing for communicating with the telephone line / public network line 33. The modem 6 is used when receiving update information of the OS and application programs and transmitting data from a user to a broadcast station or a data server. When the metadata is distributed from the telephone line / public network line 33, the modem 6 receives it.
[0032]
The broadband network interface 5 is connected to a broadband network such as DSL (Digital Subscribe Line) / CATV (Cable Television) / optical fiber among telephone lines / public network lines 33. The broadband network interface 5 is used when receiving update information of an OS or application program, or transmitting data from a user to a broadcasting station or a data server. The broadband network interface 5 is also used when the metadata is transmitted via a broadband network.
[0033]
In this hard disk recorder, a magnetic disk 41, an optical disk 42, a magneto-optical disk 43, and a semiconductor memory 44 are connected through an input / output interface 40 as necessary.
[0034]
FIG. 2 mainly illustrates a configuration example of buttons of the remote controller 21.
[0035]
The backward skip button 51 and the forward skip button 57 are operated by the user when the segment (or index) to be reproduced is skipped backward (temporally backward) or skipped forward (temporally forward), respectively. . The rewind button 52 is operated when the playback position is moved backward at high speed. The stop button 53 is operated when stopping the reproduction. The pause button 54 is operated when the playback or recording state is temporarily stopped. The playback button 55 is operated when starting playback. The fast forward button 56 is operated when the playback position is fast forwarded.
[0036]
The light emitting unit 61 incorporates an infrared light emitting element, and emits an infrared signal corresponding to the operation to the remote control light receiving unit 7 when these buttons are operated.
[0037]
Although not shown, the remote controller 21 is provided with a numeric keypad and other various buttons in addition to these buttons.
[0038]
Next, the basic operation of the hard disk recorder described above will be described.
[0039]
When the user operates the remote controller 21, the keyboard 13, or the mouse 14 to instruct reception of predetermined content, the CPU 8 controls the tuner 1 to receive the designated broadcast channel. The tuner 1 receives the radio wave of the designated channel based on the control of the CPU 8 and outputs the demodulated signal to the MPEG encoder / decoder / VRAM 4. The MPEG encoder / decoder / VRAM 4 encodes the signal supplied from the tuner 1 using the MPEG method, supplies the signal to the storage 12, and stores it.
[0040]
In this way, the content is stored in the storage 12. Corresponding metadata is transmitted from a server (not shown) via the telephone line / public network line 33, received by the modem 6, and stored in the storage 12. The metadata can also be generated uniquely by the user and stored in the storage 12. An example of metadata will be described later with reference to FIG.
[0041]
When the user operates the remote controller 21, the keyboard 13, or the mouse 14 to instruct reproduction using metadata, the CPU 8 reads out the metadata stored in the storage 12, generates a list thereof, and generates an MPEG encoder. The data is output from the decoder / VRAM 4 to the display 32 via the video signal processing circuit 3 and displayed.
[0042]
FIG. 3 shows a display example in this case. That is, in this display example, a list (segment group) corresponding to metadata and a list of segments are displayed on the display unit 104. Of these, the display unit 131 displays information relating to the entire program being reproduced. In this example, representative thumbnail images and characters “ski jump”, “1 channel (terrestrial)”, and “December 24, 17: 00-17: 50” are displayed. Here, the segment group is a virtual program in which broadcast content is reconfigured.
[0043]
A list of stories is displayed in the display unit 132 below the display unit 132. In this example, the story with the title “Special feature of Japanese players in 4 minutes” shown on the display unit 133 is selected from a plurality of stories displayed below the display unit 132 of the story list. The segments constituting the story are sequentially displayed on the display units 141-1 to 141-8. The total playback time of the story is “4 minutes 4 seconds”.
[0044]
The display unit 141-1 shows a segment whose title is “Harada, 1st” and whose playback time is “2 minutes 56 seconds” to “3 minutes 10 seconds”.
[0045]
In addition, in the display unit 141-2, a segment whose title is “Harada player, result” and whose relative reproduction time with respect to the entire content is “3 minutes 30 seconds” to “3 minutes 35 seconds” is shown. .
[0046]
The display unit 141-3 shows a segment whose title is “Funaki player, 1st” and whose playback time representing the relative position with respect to the entire content is “3 minutes 54 seconds” to “4 minutes 10 seconds”. ing.
[0047]
In addition, the display unit 141-3 displays a marker 151 indicating that the segment is currently being reproduced. The display unit 101 displays an image of the content of this segment.
[0048]
Hereinafter, similarly, the display units 141-4 to 141-8 each show a segment of a reproduction time indicating a relative position with respect to the title and the entire content.
[0049]
A scroll button 106 and a scroll button 107 are displayed at the right end of the display unit 104, and a scroll bar 105 is displayed therebetween. The user can scroll the display on the display unit 104 in the vertical direction by operating the mouse 14 with these buttons or bars.
[0050]
At the lower end of the display unit 104, a scroll button 109, a scroll button 110, and a scroll bar 108 are displayed therebetween. When these buttons or bars are operated with the mouse 14, the display on the display unit 104 is scrolled in the left-right direction.
[0051]
On the right side of the display unit 104, a display unit 101 that displays content images is provided. Below the display unit 101, a display unit 102 and a display unit 103 are provided.
[0052]
A current position display bar 121 is displayed on the display unit 102. The left end of the display unit 102 corresponds to the playback start time of the content targeted by the story (in this case, the story “Special feature of Japanese players in 4 minutes”), and the right end of the display portion 102 shows the playback of the content. Corresponds to the end time. The current position display bar 121 is displayed at a relative position defined by the playback start time and playback end time of the story. The display position of the current position display bar 121 is sequentially changed with the progress of the story reproduction.
[0053]
Further, not only the current position display bar 121 but also the segment bar 122 is displayed on the display unit 102 at a position corresponding to the reproduction range. In that case, the left end of the display unit 102 corresponds to the playback start time of the content targeted by the currently playing segment, the right end corresponds to the playback end time of the content, and the segment bar 122 is displayed at a relative position defined by the playback start time and playback end time of the content targeted by the segment. The display position of the current position display bar 121 is sequentially changed as the segment playback progresses.
[0054]
In addition, although illustration is omitted, it is of course possible to display an index bar or the like. In this case, the index bar is displayed at a relative position defined by the reproduction start time of the content targeted by the index.
[0055]
Operation buttons are displayed on the display unit 103 below the display unit 102. The “<< Skip button” at the left end constitutes a backward skip button (corresponding to the backward skip button 51 in FIG. 2) operated when skipping backward, and the “Stop button” is a stop button (stop in FIG. 2). Corresponds to the button 53). The “−10 seconds” button is operated when the playback position is moved backward by 10 seconds from the current position.
[0056]
The “Pause” button is a pause button and corresponds to the pause button 54 in FIG. The “Play” button is a playback button that is operated when playback is started, and corresponds to the playback button 55 in FIG.
[0057]
The “+10 seconds” button is operated when the playback position is moved forward by 10 seconds from the current position. The “Skip >>” button is a forward skip button and corresponds to the forward skip button 57 in FIG.
[0058]
At the right end of the display unit 103, the current display position of the image displayed on the display unit 101 is displayed as a number representing the time. In the case of the example in FIG. 3, the display unit 101 indicates that an image at a position “2 minutes 52 seconds” from the reproduction start time is displayed.
[0059]
FIG. 4 shows an example of metadata in XML (eXtensible Markup Language) format.
[0060]
In the example of FIG. 4, the target video is designated by the block 201. Area id = 'Tokyo' indicates that the area where the content is broadcast is Tokyo. Channnel network = 'Terrestrial'> 4 </ Channel> represents content broadcast on the fourth channel of the terrestrial wave. The next StartTime indicates that the broadcast start time of this content is 10:00 on May 30, 2001, and EndTime indicates that the broadcast end time is 20:00 on May 30, 2001. Represents.
[0061]
The next video index metadata block 202 represents an index as a jump destination to jump at the time of scanning. In this example, the relative time position of 5 minutes 15 seconds is designated as an index. The identification of this index is “Economic news”.
[0062]
The video segment group metadata block 203 defines two segments (seq = 1 and seq = 2).
[0063]
The start time of the segment with seq = 1 is 3 minutes 22 seconds in relative time, and the end time is 4 minutes 35 seconds in relative time. The description is “Top news”.
[0064]
In the segment with seq = 2, the relative time of the start time is 5 minutes and 15 seconds, and the relative time of the end time is 6 minutes and 35 seconds. This segment is identified by “Economic news”.
[0065]
In addition, the video segment group metadata block 203 may include icon information, memo (text) information, and the like. Each segment may also include icon information, memo information, and the like.
[0066]
When video segment group metadata is created as an index, or when scanning is commanded during playback, the video is played back by repeating the operation of sequentially jumping to the next index position.
[0067]
On the other hand, when specified as video segment group metadata, the range of each segment defined by the start point and the end point is sequentially reproduced.
[0068]
Now, for example, when the user of the hard disk recorder operates the remote controller 21, the keyboard 13, or the mouse 14 to instruct playback using metadata as shown in FIG. 4, the CPU 8 is stored in the storage 12. 3 is read out, the list is generated based on the information included in the metadata, and the screen as shown in FIG. 3 is displayed from the MPEG encoder / decoder / VRAM 4 via the video signal processing circuit 3. 32.
[0069]
Then, when the user wants to search an interesting list from the story list (segment group list) or index list (not shown) displayed on the display 32 and wants to view it, the remote controller 21, the keyboard 13 or the mouse 14 is operated to perform an operation of selecting a desired one. Alternatively, the user inputs a content to be viewed as a keyword, or performs an operation for registering preference information regarding a program genre or a keyword in the hard disk recorder in advance.
[0070]
As a result, the CPU 8 of the hard disk recorder executes a search for a segment group or a segment based on a user's desired segment selection operation, an input keyword, or pre-registered preference information, and there is a matching unit. If so, it will guide the user to view it.
[0071]
The processing in this case will be described with reference to the flowchart of FIG.
[0072]
In step S1, the CPU 8 determines whether a segment selection or keyword input operation has been performed by the user based on a signal input from the remote control light receiving unit 7, the keyboard 13, or the mouse 14, and selects a segment or inputs a keyword. When it is determined that the operation is performed, the process proceeds to step S3.
[0073]
If it is determined in step S1 that neither segment selection nor keyword input has been performed, the process proceeds to step S2, and the CPU 8 further determines whether or not keywords or preference information has been registered in advance by the user. If it is determined and it is determined that neither the keyword nor the preference information is registered, the process returns to step S1, and the above-described processing is repeatedly executed.
[0074]
If it is determined in step S2 that a keyword or preference information is registered, the process proceeds to step S3.
[0075]
In step S <b> 3, the CPU 8 searches the metadata stored in the storage 12 for a segment (including a keyword or a pre-registered segment of preference information) corresponding to the user's operation.
[0076]
For example, when an operation for selecting the display unit 141-3 is performed by the user, or when a keyword “Funaki player, first” is input, “3 minutes of metadata stored in the storage 12 is stored. The segment recorded in the section from “54 seconds” to “4 minutes and 10 seconds” is searched.
[0077]
Further, for example, when a keyword such as “Funaki player” is registered in advance by the user, the segment recorded in the section “3 minutes 54 seconds” to “4 minutes 10 seconds” of the metadata, and “4 The segment recorded in the section from “minute 34 seconds” to “4 minutes 38 seconds” is searched.
[0078]
Thus, in the case of a search by keyword input, it is possible to use a so-called fuzzy search that can search for a title name including the keyword even if the title names do not completely match.
[0079]
In step S4, the CPU 8 determines whether or not the segment group (story) is currently being reproduced. If it is determined that the segment group is currently being reproduced, the process proceeds to step S5, and further, the reproduction is in progress. It is determined whether or not the segment group includes the segment searched in the process of step S3 (for example, the segment of the title “Funaki, first” shown in the display unit 141-3). .
[0080]
In step S5, when it is determined that the searched segment is included in the segment group being played back, the process proceeds to step S6, and the CPU 8 starts playback from the searched segment.
[0081]
For example, among the segment group (story) of the title “Special feature of Japanese players in 4 minutes”, currently playing the segment of the title “Yoshioka player, first” shown in the display section 141-5 If it is, the jump is made to the playback position (in this case, the position of “3 minutes 54 seconds”) of the searched segment (segment shown in the display unit 141-3), and playback is started from that position. The Then, the reproduced image is displayed on the display unit 101.
[0082]
If it is determined in step S4 that the segment group is not currently being played back, and if it is determined in step S5 that the segment group being played back does not include the searched segment, The process proceeds to step S7.
[0083]
In step S <b> 7, the CPU 8 searches the metadata stored in the storage 12 for a segment group including the segment searched in step S <b> 3. In step S8, the CPU 8 starts playback from the first segment included in the segment group searched in step S7.
[0084]
For example, when a segment group (story) having the title “Special feature for Japanese players in four minutes” shown in the display unit 133 of FIG. 3 is searched, the first segment constituting the segment group is: Since it is a segment having the title “Harada, 1st” shown on the display unit 141-1, playback is started from the position of “2 minutes 56 seconds” which is the playback start position of the segment.
[0085]
After the process of step S6 or step S8, in step S9, the CPU 8 determines whether or not the segment group has been reproduced to the end. If it is determined that the segment group has not been reproduced to the end, the last position is determined. Wait for playback.
[0086]
If it is determined in step S9 that the segment has been played to the end, the process is terminated.
[0087]
As described above, when the segment selected by the user or the segment group including the segment based on the keyword or preference information registered (input) by the user is already being reproduced, as the user intends, A jump to the found segment is performed.
[0088]
If the segment group including the searched segment is not reproduced, a jump to the first segment of the segment group including the searched segment is executed. That is, the user is guided to view a segment group including the segment, not the designated segment itself. In this case, when the user performs an operation for selecting a desired segment again (that is, when two selection operations are performed), a jump to the segment is performed (as the user intended). Playback is performed).
[0089]
By the way, the segment group is generally edited along a certain theme (for example, “highlight scene” in a ski jump program, “goal scene” in a soccer program, etc.). Therefore, instructing the user to view a segment group including a segment selected by the user or a segment searched based on preference information is the same as that in which the user performs a gentle search. Can be expected.
[0090]
The series of processes described above can be executed by hardware, but can also be executed by software. When a series of processing is executed by software, a program constituting the software may execute various functions by installing a computer incorporated in dedicated hardware or various programs. For example, it is installed from a recording medium in a general-purpose personal computer or the like.
[0091]
As shown in FIG. 1, a recording medium for recording a program installed in a computer and ready to be executed by the computer includes a magnetic disk 41 (including a flexible disk), an optical disk 42 (CD-ROM (Compact Disc- Package media, such as Read Only Memory (DVD) (including Digital Versatile Disc), magneto-optical disk 43 (including MD (Mini-Disc) (registered trademark)), or semiconductor memory 44, or a program is temporarily stored Or it consists of a Flash ROM or hard disk that is permanently recorded. Recording of a program on a recording medium is performed using a wired or wireless communication medium such as a public line network, a local area network, the Internet, or digital satellite broadcasting via an interface such as a router or a modem as necessary. .
[0092]
In the present specification, the step of describing the program recorded on the recording medium is not limited to the processing performed in chronological order according to the described order, but is not necessarily performed in chronological order. It also includes processes that are executed individually.
[0093]
