FIG. 1 is a block diagram showing a functional configuration example of a receiver according to the first embodiment.
The receiving device 1 is, for example, a receiver for digital television broadcasting, and receives 4K/8K broadcasting signals such as advanced wideband satellite digital broadcasting, existing terrestrial digital broadcasting, BS digital broadcasting, etc. from an antenna (not shown) or cable broadcasting. 2K broadcast signals such as broadcasting and CS digital broadcasting are received. Broadcast signals of various digital broadcasts such as 4K/8K broadcast and 2K broadcast are sometimes referred to as various broadcast signals. The receiving device 1 acquires data related to content (referred to as content data) such as a video signal, an audio signal, and a character signal from a broadcast signal, and provides the content to the user. Alternatively, the receiver 1 may acquire video data for digital television broadcasting from a storage medium such as a DVD or a hard disk, or from a content server (not shown) on the Internet, instead of the broadcast signal.

The distribution unit 11 receives broadcast signal radio waves via an antenna (not shown) or a coaxial cable for cable broadcasting, and distributes the broadcast signal radio waves to one or more tuners.

The tuner unit 12 selects a broadcast signal wave of a desired frequency band from the broadcast signal wave input from the distribution unit 11, and acquires a broadcast signal (digital data) by demodulating the selected broadcast signal wave. In this embodiment, the tuner section 12 includes a plurality of tuner sections 12-1 and 12-2. The tuner units 12-1 and 12-2 can independently receive and process various broadcast signals. For example, the tuner section 12-1 may be a tuner for 4K broadcasting and 2K broadcasting (4K/2K tuner), and the tuner section 12-2 may be a tuner for only 2K broadcasting (2K tuner). A 4K/2K tuner can acquire either a 4K broadcast signal or a 2K broadcast signal. A 2K tuner can acquire only broadcast signals of 2K broadcasts. Also, in the tuner units 12-1 and 12-2, for example, one tuner (sometimes referred to as a first tuner) can receive signals with the other tuner (sometimes referred to as a second tuner). Any combination may be used as long as it is possible to receive broadcast signals of broadcast types that partially overlap among the broadcast signals of the broadcast types. For example, the first tuner can be a 4K/2K tuner and the second tuner can be an 8K/4K tuner. Also, the first tuner can be an 8K/4K/2K tuner and the second tuner can be an 8K/4K tuner.

The data processing unit 13 processes the broadcast signal output from the tuner unit 12 according to the digital broadcasting standard, and acquires and outputs content data and the like.

Rambling processing, error correction code decoding processing, encryption decoding processing for decoding encrypted data, decoding of encoding (video encoding, audio encoding, character encoding, etc.) applied to each content data It acquires and outputs content data such as video, audio, and text through processing. The data processing section 13 according to this embodiment may include independent data processing sections 13-1 and 13-2 corresponding to the tuner sections 12-1 and 12-2, respectively. For example, if the tuner section 12-1 is a 4K/2K tuner, the data processing section 13-1 can process both 4K broadcast and 2K broadcast signals. On the other hand, if the tuner section 12-2 is a 2K tuner, the data processing section 13-2 can process only broadcast signals of 2K broadcast. The data processing unit 13 can also output not only content data but also data in the process of being processed, for example, encoded data that has not been decoded (video encoded data, audio encoded data, character encoded data, etc.). It is possible. Content data and data in process are sometimes called broadcast signal processing data.

For example, when the user designates the broadcast type, broadcast format (BS/CS/digital terrestrial broadcasting/Internet, etc.), channel, etc. of content to be viewed from the remote controller 10, the control unit 16, via the interface unit 18, It receives a command signal from the remote controller, controls the functions of the television receiver 1, and causes the operation specified by the user. Also, the control unit 16 of the present embodiment outputs a command to the switching unit 14 and controls the output of the broadcast signal processing data to the presentation unit 15 and the recording/reproducing unit 17 by the switching unit 14 . In FIG. 1, data may also be exchanged with functional blocks that are not particularly connected to the control unit 16 . For example, when the control unit 16 receives a command signal designating a channel from a remote controller, the control unit 16 causes the tuner unit 12 to select and receive broadcast signal radio waves in the frequency band of the designated channel, and demodulate them. It's okay.

More specifically, the transition of the tuner state will be described by taking as an example a case where the user in the tuner state TS1 is viewing a presented program of 4K broadcasting. In TS1, recording reservation for 4K broadcasting is made, and when the user selects a channel to view 2K broadcasting, the tuner state temporarily shifts to TS7. That is, the 4K/2K tuner was used for viewing in TS1, but the user selects a channel to switch the viewing tuner to the 2K tuner (as a result, the tuner state shifts to TS7). In TS7, a 4K/2K tuner is assigned as a tuner for recording a recording reservation program of 4K broadcasting. As a result, the tuner state shifts to TS4. In this way, considering the broadcast type of the presented program that the user views and the broadcast type of the recording reservation program, the tuner state is changed to TS1, TS7, and TS4, so that the user can select the channel for viewing the 2K broadcast. is selected and the tuner for viewing by the user is switched to the 2K tuner just before viewing the presented program. The presentation program to watch is continuous. If the user continues to use the 4K/2K tuner to receive the presented program of the 2K broadcast to be viewed by the user, when the recording of the reserved program of the 4K broadcast starts, the 4K/2K tuner is used to receive the reserved program of the 4K broadcast. is used, the presented program viewed by the user is interrupted. The tuner state transitions in this case correspond to TS1, TS6, and TS4. In this case, the presented program that the user views is interrupted at the transition from TS6 to TS4.

FIG. 2B(b) is an example in which the tuner section 12-1 is an 8K/4K/2K tuner and the tuner section 12-2 is a 2K tuner. This is an example when the /2K tuner is changed. Let the 8K/4K/2K tuner be T1 and the 2K tuner be T2. Since the view of the figure is the same as that of FIG. 2B(a), the explanation is omitted.

(First embodiment)
In the present embodiment, after the user turns on the power of the receiving device 1, before the presentation unit 15 of the receiving device 1 presents the broadcast program, the receiving device 1 is set to the presented program tuner and the scheduled recording program. An example of operation for determining a tuner will be shown.

FIG. 3 is a flowchart for a tuner selection process performed by the control unit in the receiving device according to the embodiment when the power of the receiving device is turned on.
The user transmits a remote control signal for turning on the power to the receiving device 1 from the remote control in order to view the content on the receiving device 1 . The central control unit 164 receives a remote control signal via the interface unit 18 and performs processing for turning on the power of the receiving device 1 (step S101). When the receiver 1 is powered on, the tuner section 12 starts processing broadcast signal radio waves received via the distribution section 11 and outputs the broadcast signal to the data processing section 13 . When the data processing unit 13 outputs the broadcast signal processing data obtained by processing the broadcast signal to the switching unit 14 , the switching unit 14 outputs the broadcast signal processing data to the control unit 16 . The program information analysis unit 161 of the control unit 16 determines the broadcast type of the broadcast program being received from the control signal (SI signal) of the broadcast signal processing data (corresponding to the presented program broadcast type, but the program is not yet presented by the presentation unit 15). not used). The central control unit 164 acquires the broadcast type of the presented program extracted from the program information analysis unit 161 (presented program broadcast type), and acquires the current tuner state from the switching management unit 16 . Further, the broadcast type (recording reserved program broadcast type) of the broadcast program to be recorded in the near future is acquired from the recording management unit 162 (step S102). The central control unit 164 determines whether or not it is necessary to change the tuner state based on the acquired presentation program broadcast type, current tuner state, and recording reserved program broadcast type (step S103). More specifically, case number 1 in FIG. 2B(a) will be described as an example.

In FIG. 2B(a), the designation column 204 indicates the tuner state immediately after the power of the receiving apparatus 1 is turned on, and the designation column 202 indicates the broadcast type of the presented program to be received and the broadcast type of the recording reservation program to be received. be In the case of case number 1, as shown in the designation column 202, the broadcast type of the received presentation program is 2K broadcast, and the broadcast type of the received recording reservation program is 2K broadcast. Also, as shown in the left column of the designation column 204, T1 (4K/2K tuner) is set as the presentation program tuner. On the other hand, as shown in the right column of the designation column 204, T2 (2K tuner) is set as the reserved program tuner. That is, in case number 1, the tuner of the program reserved for recording and the tuner of the presented program do not overlap, so the central control unit 164 determines that the tuner has not been changed (NO in step S103). A designation column 204 indicates the tuner state after the central control unit 164 has determined whether or not the tuner needs to be changed.

Next, using case number 3, an example in which there is a change in the tuner state (the specified column 206 is "yes") will be described.

In FIG. 2B(a), the designation column 204 indicates the tuner state immediately after the power of the receiving apparatus 1 is turned on, and the designation column 202 indicates the broadcast type of the presented program to be received and the broadcast type of the recording reservation program to be received. be

In the case of case number 3, as shown in the designation column 202, the broadcast type of the received presentation program is 2K broadcast, and the broadcast type of the received recording reservation program is 4K broadcast. Also, as shown in the left column of the designation column 204, T1 (4K/2K tuner) is set in the switching unit 14 as the presentation program tuner. On the other hand, as shown in the right column of the designation column 204, T1 (4K/2K tuner) is set as the recording reserved program tuner. Therefore, in case number 3, there is overlap between the scheduled recording program tuner and the presented program tuner. In this state, when recording is started while the user is viewing the presented program, the recording of the program reserved for recording is prioritized, the presented program tuner is switched to T2 (2K tuner), and the presented program is interrupted during viewing. problems occur. Therefore, in this case, the central control unit 164 determines that it is necessary to switch the presented program tuner at this point (YES in step S103). Since the presented program broadcast type is 2K broadcasting, the central control unit 164 selects T2 (2K tuner), which is not set as a recording reserved program tuner, from the available tuners shown in the designation frame 203 as a presented program tuner, It is set in the switching unit 14 (step S104). The switching unit 14 acquires the content data of the presentation program from the set T2 (2K tuner), outputs it to the presentation unit 15, and is provided from the presentation unit 15 to the user as content. Further, when the recording of the program reserved for recording is started, the switching unit 14 acquires the program reserved for recording from the T1 (4K/2K tuner), outputs the acquired content data to the recording/reproducing unit 17, and records the program. The reserved program is recorded in the recording/reproducing section 17 . A designation column 204 indicates the tuner state after the central control unit 164 determines whether or not the tuner needs to be changed. In the case of case number 3, the tuner state needs to be changed, so the transition of the designation column 206 is "yes".

With the above procedure, when recording of a program reserved for recording different from the program being viewed by the user starts while the user is viewing the program, recording of the program reserved for recording is performed without interrupting the program being viewed. be able to. Note that the central control unit 164 may prohibit the output of the presented program to the presentation unit 15 from when the power of the receiving device 1 is turned on until the tuner switching process is completed in step S104.

(Second embodiment)
In the present embodiment, when the user selects a channel for the receiving device 1, the operation when the receiving device 1 determines the presented program tuner and the scheduled recording program tuner to be used for the most recent scheduled recording execution. Give an example.

FIG. 4 is a flowchart for the receiving apparatus according to the second embodiment to perform tuner selection processing when the user selects a channel. The operation of the device 1 will be explained.

The receiving device 1 is powered on, and content data is being output to the presentation unit 15 from the tuner unit 12-1 and the data processing unit 13-1, for example. In this situation, in order to change the content (presented program) to be viewed on the receiving device 1, the user performs a tuning operation to change the channel set for the broadcast program using the remote control 10 (step S151). The central control unit 164 receives a remote control signal for channel designation from the remote control 10 via the interface unit 18 . The central control unit 164 analyzes the received remote control signal related to channel designation, and identifies the broadcast program (presentation program) designated by the remote control signal (step S152). The central control unit 164 acquires necessary information based on the specified presented program (step S153). Specifically, the central control unit 164 acquires the specified program broadcast type (presented program broadcast type) from the program information analysis unit 161 and acquires the current tuner state from the switching management unit 16 . The central control unit 164 determines whether there is a change in the tuner state based on the acquired presented program broadcast type, the current tuner state, and the recording reserved program broadcast type stored in a memory (not shown). It is determined whether tuner switching is necessary at the time of reservation execution (step S154). The case where there is a change in the tuner state (YES in step S154) will be described more specifically by taking case number 3 in FIG. 2B(a) as an example.

In the case of case number 3, as shown in the designation column 202, the broadcast type of the presented program is 2K, and the broadcast type of the program reserved for recording is 4K. Also, as shown in the designation column 204, the tuner units (current tuner states) assigned to the presented program and the recording reservation program determined in step S202 are T1 (4K/2K tuner). Since the recording of the program reserved for recording has not yet started at present, it is possible to output the presented program to the presentation unit 15 from T1, and the user can view the presented program. However, if the recording of the program reserved for recording starts in this state, if the recording of the program reserved for recording is given priority, T1 is used to receive the program reserved for recording. Output is interrupted. As a result, the presented program that the user is viewing is interrupted. Therefore, in the present embodiment, the central control unit 164 needs to change the tuner of the presented program based on the acquired presented program broadcast type, the current tuner state, and the recording reserved program broadcast type stored in a memory (not shown). Determine whether or not Here, the acquired presentation program broadcast type and recording reserved program broadcasting type are shown in the designation column 202 in FIG. is 4K broadcasting. The acquired current tuner status is shown in the designation column 204 of FIG. When the central control unit 164 confirms that there is an overlap between the presented program tuner and the recording reserved program tuner, the central control unit 164 refers to the available tuners shown in the designation column 203 and checks whether the presented program tuner can be switched. do. In case number 3, since the presented program is 2K broadcasting, T2 can be used, so the central control unit 164 switches the presented program tuner to T2 (step S155).

On the other hand, when there is no change in the tuner state (NO in step S154), case number 1 in FIG. 2B(a) will be described more specifically as an example. In case number 1, as shown in the designated column 202, the broadcast type of the presented program is 2K, and the broadcast type of the program reserved for recording is 2K. As shown in the designation column 204, T1 (4K/2K tuner) is assigned to the presentation program determined in step S152, and T2 (2K tuner) is assigned to the program reserved for recording. That is, in case number 1, the tuner of the program reserved for recording and the tuner of the presented program do not overlap, so the central control unit 164 determines that the tuner is not changed, and does not control the switching unit 14 (NO in step S154). .

According to the above procedure, when the user selects a channel, that is, by determining the tuner for the presented program and the recording reserved program to be displayed on the presentation unit 15, the user can select the program being viewed while viewing the presented program. When the recording of the program reserved for recording different from the program starts, the program reserved for recording can be recorded without interrupting the program being viewed.

(Third embodiment)
In the present embodiment, an operation example in which the receiving device 1 determines the presented program tuner and the recording reserved program tuner while the user is zapping the receiving device 1 will be described. Zapping is an operation in which a user quickly moves a channel set for a broadcast program among a plurality of channels using a remote control or the like in order to select a broadcast program for the user to view.

FIG. 5 is a flowchart for the receiver according to the third embodiment to perform tuner selection processing when the user performs zapping. to explain the operation of

The receiving device 1 is powered on, and content data is being output to the presentation unit 15 from the tuner unit 12-1 and the data processing unit 13-1, for example. In this situation, the user performs a zapping operation of changing the channel set for the broadcast program using the remote controller 10 in order to change the content (presented program) viewed on the receiving device 1 . The central control unit 164 receives a remote control signal for channel designation from the remote control 10 via the interface unit 18 . When the user performs a zapping operation, the central control unit 164 receives a plurality of remote control signals related to channel designation in a short period of time. For example, the central control unit 164 may determine that the user is performing a zapping operation (referred to as a zapping state) when remote control signals related to channel designation arrive continuously within time T_C. When the zapping state is established (YES in step S201), the central control unit 164 analyzes the received remote control signal related to channel designation, and identifies the broadcast program (presentation program) designated by the remote control signal (step S202). The central control unit 164 acquires necessary information based on the specified presented program (step S203). Specifically, the central control unit 164 acquires the specified program broadcast type (presented program broadcast type) from the program information analysis unit 161 and acquires the current tuner state from the switching management unit 16 . The central control unit 164 determines whether or not there is a change in the tuner state based on the acquired presented program broadcast type, the current tuner state, and the recording reserved program broadcast type stored in a memory (not shown) (step S204). ). The case where there is a change in the tuner state (YES in step S204) will be described more specifically, taking case number 3 in FIG. 2B(a) as an example.

In the case of case number 3, as shown in the designation column 202, the broadcast type of the presented program is 2K, and the broadcast type of the program reserved for recording is 4K. Also, as shown in the designation column 204, the tuner units (current tuner states) assigned to the presented program and the recording reservation program determined in step S202 are T1 (4K/2K tuner). Since the recording of the program reserved for recording has not yet started at present, it is possible to output the presented program to the presentation unit 15 from T1, and the user can view the presented program. However, if the recording of the program reserved for recording starts in this state, if the recording of the program reserved for recording is given priority, T1 is used to receive the program reserved for recording. Output is interrupted. As a result, the presented program that the user is viewing is interrupted. Therefore, in the present embodiment, the central control unit 164 needs to change the tuner of the presented program based on the acquired presented program broadcast type, the current tuner state, and the recording reserved program broadcast type stored in a memory (not shown). Determine whether or not Here, the acquired presentation program broadcast type and recording reserved program broadcasting type are shown in the designation column 202 in FIG. is 4K broadcasting. The acquired current tuner status is shown in the designation column 204 of FIG. When the central control unit 164 confirms that there is an overlap between the presented program tuner and the recording reserved program tuner, the central control unit 164 refers to the available tuners shown in the designation column 203 and checks whether the presented program tuner can be switched. do. In the case of case number 3, since the presented program is a 2K broadcast, T2 can be used. "Yes" is set to the change flag of the presenting program tuner (step S205). Also, the central control unit 164 stores the presentation program tuner determined here.

On the other hand, when there is no change in the tuner state (NO in step S204), case number 1 in FIG. 2B(a) will be described more specifically as an example. In case number 1, as shown in the designated column 202, the broadcast type of the presented program is 2K, and the broadcast type of the program reserved for recording is 2K. As shown in the designation column 204, T1 (4K/2K tuner) is assigned to the presentation program determined in step S202, and T2 (2K tuner) is assigned to the program reserved for recording. That is, in case number 1, since the tuner of the program reserved for recording and the tuner of the presented program do not overlap, the central control unit 164 determines that the tuner is not changed. The tuner change flag is set to "none" (NO in step S204).

The central control unit 164 determines that zapping is continuing if, for example, the remote control signal for channel designation is received next within time T_C after the remote control signal for channel designation is received first. , return to step S202 and repeat the operation (NO in step S207). On the other hand, if the central control unit 164 determines that zapping has ended (YES in step S207), it checks the change flag. The switching unit 14 is controlled to change the tuner output to the presentation unit 15 to the presentation program tuner determined during zapping (step S209). The central control unit 164 checks the change flag, and does not control the switching unit 14 if the change flag is set to "none" (NO in step S208).

By determining the tuner for the presented program and the program reserved for recording according to the above procedure while the user is zapping, it is possible to set the recording reservation for the program different from the program being viewed while the user is viewing the presented program. When the recording of the program is started, the program reserved for recording can be recorded without interrupting the program being viewed.

(Modification)
In the first embodiment and the second embodiment, the examples of case number 1 and case number 3 in FIG. 2B(a) are shown, but in this modified example, an example of another case in FIG. 2B will be described. do.

Case No. 5 in FIG. 2B(a) is an example of changing the tuner of the program reserved for recording.

In case number 5, as shown in the designated column 202, the broadcast type of the presented program is 4K, and the broadcast type of the program reserved for recording is 2K. Also, as shown in the designation column 204, the tuner units (current tuner states) assigned to the presented program and the program reserved for recording are T1 (4K/2K tuner), respectively. Therefore, in case number 5, there is overlap between the scheduled recording program tuner and the presented program tuner. However, the broadcast type of the presented program is 4K, and T1 (4K/2K tuner) must be used to present the presented program. Therefore, in this case, the central control unit 164 can switch the recording reserved program tuner to T2 (2K tuner) and change the tuner state as shown in the designation column 205 . However, in this case, the program reserved for recording does not have priority over the presented program.

Case number 7 in FIG. 2B(a) is an example of changing the broadcast type of the presented program.

In case number 7, as shown in the designation column 202, the broadcast type of the presented program is 4K, and the broadcast type of the program reserved for recording is 4K. Also, as shown in the designation column 204, the tuner units (current tuner states) assigned to the presented program and the program reserved for recording are T1 (4K/2K tuner), respectively. Therefore, in case number 7, there is overlap between the scheduled recording program tuner and the presented program tuner. However, the broadcast types of the presented program and the program reserved for recording are both 4K, and it is necessary to use T1 (4K/2K tuner) for both. Therefore, in this case, the central control unit 164 uses the recording reserved program tuner as T1 (4K/2K tuner), changes the broadcast type of the presented program as necessary, and changes the broadcast type of the presented program to T2. (2K tuner) It is also possible to change the tuner state as shown in the designated column 205 by switching. However, in this case, since it is necessary to be able to change the broadcast type of the presented program, switching is not normally performed in such a case. FIG. 2B(b) is an example in which T1 is an 8K/4K/2K tuner and T2 is a 2K tuner. This is an example of changing the broadcast type of the presented program and the tuner as needed, similar to case number 7 in FIG. In the example shown in FIG. 2B(b) as well, by applying the embodiments shown in the first embodiment and the second embodiment, recording reservation can be made without interrupting the presented program that the user is viewing. Program recording can be started.

According to at least one embodiment described above, it is possible to provide a receiving device, a receiving method, and a program that allow a program being viewed to be viewed without interruption when recording is started.
