Example 1
A first embodiment of the present invention will be described below with reference to FIGS.
This embodiment exemplifies a case where the present invention is applied to a mobile phone device as a mobile terminal device, and FIG. 1 is a block diagram showing basic components of the mobile phone device with a TV broadcast viewing function. In addition to a call function, a mail function, an Internet connection function (Web access function), etc., this mobile phone device is provided with a TV broadcast viewing function, a recording function, a playback function, and the like. This TV broadcast viewing function is capable of simultaneously receiving TV broadcasts for two channels by a double tuner built in the main body of the apparatus. In this embodiment, broadcast contents for two channels can be output at the same time. Can be recorded and the other can be recorded, or two channels can be recorded simultaneously. The recording function is to record the received TV broadcast (including recording), and the playback function is to play back the recorded TV broadcast. The playback output follows the recorded content while continuing the recording operation. Chasing playback is possible.

  The CPU 1 is a central central processing unit that controls the overall operation of the mobile phone device according to various programs in the storage unit 2. In addition to the main CPU 1, the mobile phone device includes, for example, video A structure having a plurality of sub CPUs (not shown) for each function such as a sound data transmission / reception function and a received video recording / playback function. The storage unit 2 is a non-volatile memory (internal memory), and is configured by, for example, a flash memory, and has a program area and a data area. In the program area, operations shown in FIGS. A program for realizing the present embodiment is stored according to the procedure.

  The recording medium 3 is a removable portable memory that supplies image data, various types of data, and programs to the outside. The recording medium 3 includes, for example, smart media and an IC card. The memory 4 is an internal memory having a work area, and is composed of, for example, DRAM, SDRAM (Synchronous DRAM) or the like. The memory 4 is provided with a reception data storage unit 21, a condition data storage unit 22, a recording data storage unit 23, a viewing time timer 24, and the like which will be described later. Various data in the memory 4 are stored as necessary. Saved in the storage unit 2.

  The telephone communication unit 5 constitutes a mobile phone communication function. After the signal is received from the receiving side of the transmission / reception unit (baseband unit) connected to the antenna 5A and demodulated into a reception baseband signal, the acoustic control unit 6, the voice is output from the reception speaker 7. In addition, the telephone communication unit 5 takes in the voice data input from the transmission microphone 8 from the acoustic control unit 6, encodes it into a transmission baseband signal, gives it to the transmission side of the transmission / reception unit, and outputs the transmission from the antenna 5 </ b> A. Let On the other hand, the display data received and acquired via the telephone communication unit 5 by the mail transmission / reception function, the television broadcast reception function, and the Web access function is sent to the main display unit 10 including an LCD (liquid crystal display device) via the display control unit 9. Is output for display.

 The main display unit 10 displays character information, TV video data, various messages, and the like with high quality, and the sub display unit 11 provided on the back side of the apparatus main body displays the current date and time, simple messages, icons, and the like. To do. The key operation unit 12 performs dial input, character input, command input, and the like. For the TV function, a TV ON / OFF key, a channel switching key, a recording start key for instructing recording of TV broadcasting, and playback of recorded contents are performed. It has a playback key for instructing. Note that each key for the TV function may be a touch key arranged on the TV screen of the main display unit 10.

 The two TV broadcast receiving tuners 13 and 14 receive terrestrial digital TV broadcasts for portable receivers such as mobile phones and receive electronic program guides (EPG) in addition to TV video and audio information. Is possible. The TV broadcast receiving tuners 13 and 14 have a receiving unit connected to the TV antenna 15, an amplification / separating unit that separates the received TV broadcast into a video signal and an audio signal, a decoding unit that decompresses compressed data, and the like. The TV video signals output from the TV receiving tuners 13 and 14 are displayed and output from the main display unit 10, and the TV audio signal is output from the built-in speaker (high sound pressure speaker) 16. Note that an OFDM (orthogonal frequency division multiplexing) demodulator may be connected in order to reduce the size of the television broadcast receiving tuners 13 and 14. The RTC (real-time clock module) 17 constitutes a clock unit, and the CPU 1 acquires the current date and time from the RTC 17.

FIG. 2 is a diagram showing the contents of the received data storage unit 21.
The received data storage unit 21 stores terrestrial digital television broadcast program contents (video / audio data as well as information related to the program) as “channel”, “attribute”, “program information”, and “video / audio data”. “Channel” indicates an identification number of the reception channel, and the example shown is a case where “10” is set. “Attribute” indicates the type of received broadcast, and the example shown is a case where “TV program” is set. The “program information” has items of “genre name”, “program name”, and “date / time” as various information about the program. In the example shown in the figure, “soccer” and “program name” are used as the “genre name”. This is a case where “competitive team name” is set and “broadcast date” is set as “date and time”.

FIG. 3 is a diagram showing the contents of the condition data storage unit 22.
The condition data storage unit 22 is capable of storing a plurality of records of determination conditions for determining whether or not there is a probability of viewing the broadcast content of the channel before the change after that when channel change is instructed. The condition record has items of “viewing time”, “program information”, and “during CM broadcasting”. This determination condition is arbitrarily set in consideration of the trend (viewing trend) of the viewer (user) at the time of channel switching. When the channel switching change is instructed, the CPU 1 determines the channel ( Whether or not the original channel) satisfies the conditions of “viewing time”, “program information” and “CM broadcast” (logical product condition) is determined, and when the condition is satisfied, the broadcast contents of the channel before the change The recording operation for recording is started.

 “Viewing time” indicates the time during which the broadcast content of the channel before the change was continuously viewed until the channel switching change was instructed. If this viewing time is long, the channel is temporarily changed during the broadcast. Even if it is switched, the probability of continuing to watch after that becomes high, so it is set as the determination condition. In the example shown in the figure, “10 minutes or more” is set for “viewing time” as a condition common to all records, but a different “viewing time” may be set for each record. .

 “Program information” indicates the program contents of the channel before the change, and even if the channel is temporarily switched during the broadcast of the program of interest, favorite program, etc., there is a high probability that it will continue to be viewed after that. In addition, “genre name”, “program name”, and the like are set as the determination conditions. In the illustrated example, the first condition indicates that “soccer” is set as the keyword of “genre name”, and the second condition is “music program” as the keyword of “genre name”. Set, the 3rd condition shows “drama title” as “program name” keyword, and the 4th condition shows “baseball” as “genre name” keyword Yes.

 “CM broadcast” is because the frequency of channel switching is high during the broadcast of TV commercials, so even if the channel is temporarily switched during CM broadcast, there is a high probability that it will continue to be viewed after that. As the determination condition, an “on / off” flag is set. In the illustrated example, “ON” is set for the first to third “CM broadcasting”, and “OFF” is set for the fourth “CM broadcasting”. In the case of baseball broadcasts, channels may be temporarily switched even when CM broadcasts are not being performed, such as pitcher change, substitute hits, etc. In order to support channel switching other than during CM broadcasts, An “off” flag is set as a condition of “broadcasting”.

FIG. 4 is a diagram showing the contents of the recorded data storage unit 23.
The recording data storage unit 23 stores the recording data during the recording operation of the channel before the change that is started when the condition stored in the condition data storage unit 22 is satisfied. The “channel”, “recording flag”, “recording date / time”, “attribute”, “program information”, and “video / audio data” are stored. “Channel” indicates a recording target channel, “Recording flag” indicates “1” during recording / recording completion “0”, and “Program information” indicates “Genre name”, “Program name”, “ "Date" item.

  Next, the concept of operation when viewing a television broadcast in the first embodiment will be described with reference to the flowcharts shown in FIGS. Here, each function described in these flowcharts is stored in the form of a readable program code, and operations according to the program code are sequentially executed. In addition, the operation according to the above-described program code transmitted via the transmission medium can be sequentially executed. This is the same in other embodiments described later. In addition to the recording medium, the program / data supplied from the outside via the transmission medium can be used to execute operations specific to this embodiment.

FIG. 5 is a flowchart showing an operation at the time of viewing a television broadcast that is executed when the television broadcast viewing function is activated and an instruction to start viewing is given.
First, the CPU 1 activates one of the television broadcast receiving tuners 13 and 14 to start broadcast reception of the currently selected channel (step A1), and displays the video data of the received television program as a main display unit. 10 and output audio data from the built-in speaker 16 (step A2). Then, the process proceeds to a viewing time measurement process in order to measure the time during which the broadcast content of the current channel is being viewed, and the viewing time timer (addition type soft timer) 24 in the memory 4 is cleared to start (step A3).

 In this state, when a user has instructed condition setting for storing arbitrary condition data in the condition data storage unit 22 (YES in step A4), the process proceeds to the next condition setting process (step A5). In this case, a condition setting screen as shown in FIGS. 8A to 8C is displayed, and the condition data is sequentially set in this setting screen. The setting screen is provided with a determination button BT0 for confirming the input condition data. (A) is a setting screen for viewing time. When a desired “viewing time” is input in response to a guidance display prompting input of “viewing time”, the screen is switched to the program information setting screen shown in (B). The

 In this program information setting screen, each item of “program information” is displayed as a selection candidate, and when an arbitrary item is selected and designated from the list display, it is switched to a setting screen corresponding to the selected item. . (C) is a setting screen when the item of “genre name” is selected, and a desired keyword of “genre name” is input in this input area. Hereinafter, the item data is input while arbitrarily selecting the item of “program information”. Then, “ON / OFF” is input and set as the condition data of “CM broadcasting”. A condition record is generated based on the “viewing time”, “program information”, and “CM broadcast” input in this manner and stored in the condition data storage unit 22.

 During the television broadcast output, the CPU 1 checks whether or not a channel switching operation has been performed (step A6), and will be described later when switching from the channel currently being broadcast output to another channel (new channel) is instructed. The process proceeds to the channel switching process (step A7). When the CM detection timing (for example, 1 second interval) is reached (YES in step A8), the process proceeds to the CM detection process described later (step A9). When an end operation for instructing the end of viewing is performed (YES in step A10), a viewing end process for stopping TV output / recording output is performed (step A11), but other operations are performed. In this case (YES in step A12), for example, processing such as display adjustment and volume adjustment is performed as processing corresponding to the operation key (step A13).

FIG. 6 is a flowchart detailing the channel switching process.
First, after ending the measuring operation of the viewing time timer 24 in response to the channel switching operation (step B1), the CPU 1 accesses the condition data storage unit 22 (step B1), and displays “program” in each condition record. The “information” is compared with the “program information” of the program broadcast on the channel before the change at the time of channel switching, and it is determined whether it matches the “program information” of any condition (step B2). Here, if none of the conditions is met (NO in step B2), the broadcast reception of the channel before the change is terminated as the condition is not satisfied (step B3).

 Now, if the program content of the channel before the change matches any of the conditions of “program information” (YES in step B2), for example, if the conditions as shown in FIG. If the program of the channel is “soccer”, it matches the “program information” of the first record, so that “viewing time” is read from the corresponding condition record (step B4), and the measurement is performed from the viewing time timer 24. Time is acquired (step B5), and it is checked whether or not the measured time is “viewing time” or more (step B6).

 Here, if it is less than “viewing time”, the broadcast reception of the channel before the change is terminated because the condition is not satisfied (step B3), but if it is “viewing time” or more, the corresponding record (first condition record) ) Is read out and the “ON / OFF” flag is checked (step B 7). If the “CM broadcasting” flag is “OFF”, at this time If the condition is established, but the flag is “ON”, the received data storage unit 21 is referred to and it is checked whether the channel before the change is in the CM broadcast at the time of channel switching (step B8). . Here, if the CM is not being broadcast, the broadcast reception of the channel before the change is terminated as the condition is not satisfied (step B3), but if the CM is being broadcast, the satisfaction of the condition is detected.

 That is, in the example of FIG. 3, when moving to a CM broadcast in the middle of a soccer program that has been watched for 10 minutes or more, the establishment of a condition is detected when the channel is switched during the CM broadcast. When a channel is switched during a baseball program that has been watched for 10 minutes or more, the establishment of a condition is detected regardless of whether the CM is being broadcast. When the satisfaction of the condition is detected in this manner, the “condition satisfaction flag” in the memory 4 is turned “ON” (step B9), and then a recording operation for recording the program content being broadcast on the channel before the change is started (step B9). B10). If the program is just before the end of recording (for example, 5 minutes before the end), the recording is not automatically started, a message to that effect is displayed, and a message inquiring whether recording is possible is displayed. It may be. In this case, “video / audio data” is sequentially recorded in the recording data storage unit 23 following “channel”, “recording flag”, “recording date / time”, “attribute”, and “program information”. The recording operation is automatically stopped by setting the end time of the program as the recording end time.

 On the other hand, the current channel switching is switching to a channel with recording data, that is, referring to the recording data storage unit 23 to determine whether recording data is stored in association with the changed channel (step B11). In the case of switching to a channel in which recording data is stored, a confirmation message for inquiring whether or not to reproduce is displayed together with a message indicating the presence of recording (step B12). FIG. 9 shows a state in which the message screen is superimposed on the television screen. On the television screen, a viewing button BT1 and a playback button BT2 are provided as touch buttons. In this state, when the viewing button BT1 for instructing the television viewing is operated (YES in step B13), broadcast reception of the changed channel (new channel) is started (step B14), and the received video data is received. After outputting from the main display unit 10 and outputting audio data from the built-in speaker 16 (step B15), the process proceeds to a viewing time measuring process, and the viewing time timer 24 in the memory 4 is cleared and started (step B16).

 When the playback button BT2 for instructing recording / playback is operated (NO in step B13), the “recording flag” in the recording data storage unit 23 is referred to determine whether recording is currently being performed (step B17). If recording is in progress, follow-up playback is started to play back the recorded content while continuing the recording operation (step B18). If not being recorded (NO in step B17), the recorded content is played back at normal speed. The normal reproduction is started (step B19). This chasing playback is slightly faster than the normal playback speed, and when it catches up with the television broadcast, the recording playback is switched to the television reception output (new channel). When such channel switching processing ends, the process returns to step A4 in FIG.

On the other hand, when the CM detection timing is reached (YES in Step A10), the process proceeds to CM detection processing (Step A11).
FIG. 7 is a flowchart for explaining the CM detection process in detail.
First, the CPU 1 checks whether the “condition establishment flag” is “ON / OFF” (step C1), and if the “condition establishment flag” is “ON”, the CM in the original channel (the channel before the change). It is checked whether the broadcast has ended (step C2). If the “condition establishment flag” is “off” or the CM broadcast is in progress, the CM detection process is terminated. If the end of the CM broadcast is detected, the end of the CM broadcast is indicated on the TV screen. The message is displayed and output (step C3).

 FIG. 10 shows a message screen for ending the CM broadcast, in which a CM broadcast end message on the original channel and a confirmation message for inquiring whether to switch to the original channel or keep the current channel are displayed and output. On the television screen, a viewing button BT3 and a switching button BT4 are provided as touch buttons. Here, when the user continues to watch the television broadcast of the current channel, the viewing button BT3 is operated, and when switching to the original channel, the switching button BT4 is operated. If the viewing button BT3 is operated (YES in step C4), the process returns to step A4 in FIG. 5, but if the switching button BT4 is operated (NO in step C4), the channel switching in FIG. Move on to processing (step A7). In this case, in the channel switching process, it is detected that the recording data is switching to a certain channel, and since it is detected that the recording is being performed, chasing playback of the recorded content is started.

 As described above, in the first embodiment, when the CPU 1 is instructed to change the channel in the state where the arbitrary condition is stored in the condition data storage unit 22, the channel before the change is stored in the condition data storage unit. It is determined whether or not the condition stored in 22 is satisfied, and if the condition is satisfied, a recording operation for recording the broadcast content of the channel before the change is started, so that the channel is switched after temporary switching. However, when there is a probability that the broadcast content of the channel before the change is viewed, the recording operation of the channel can be executed, and as a harmful effect associated with the channel switching, it is possible to prevent the broadcast content before the change from being overlooked. In other words, in order to effectively prevent the adverse effects of channel switching, recording is not started every time the channel is switched, but recording is started when the user thinks it is necessary according to the user's viewing trend or the like. This is advantageous in terms of power consumption and memory capacity.

  In addition, when the condition is satisfied when the channel change is instructed, the CM end detection operation is executed on the channel before the change, and a message screen informing that is displayed according to the end detection. Thus, it is possible to return to the original channel immediately after the end of the CM broadcast. In this case, instead of starting the CM end detection operation every time the channel is switched, the CM end detection operation can be started when the user thinks it is necessary according to the viewing trend of the user. In this case, even if the condition is met when the channel is changed, if the CM is being broadcast on the channel before the change, the recording is temporarily suspended, and the recording is started when this CM is finished. Skipping is possible.

Since arbitrary “viewing time” and “program information” are stored in the condition data storage unit 22, it is possible to set conditions in consideration of user viewing trends. In this case, “genre name”, “program name”, etc. can be set in detail as “program information”. Further, since “CM broadcasting” is a condition, channel switching during CM broadcasting can be regarded as temporary switching. Furthermore, since the presence / absence of the condition is determined based on the logical product of a plurality of conditions, it is possible to greatly narrow down the recording targets.
In addition, when returning to the channel before the change, since the chasing playback that plays back the recorded contents while starting the recording operation is started, the playback time can be shortened. It is possible to switch to reception output during broadcasting.

In the first embodiment described above, “genre name” and “program name” are shown as “program information”, but “broadcast date”, “performer name”, etc. are very good. “Broadcast date / time” indicates the start date / time and end date / time of the desired program, and “Performer name” indicates the main person (actor, singer, etc.) appearing on the program. Representative players.
In the first embodiment described above, whether or not the condition is established is determined by the logical product of a plurality of conditions. However, the condition may be a logical sum condition, and two or more of the plurality of conditions may be used. If the conditions match, it may be determined that the conditions are met.

In addition, in order to prevent a large amount of data from being stored in the recorded data storage unit 23, if the recorded data recorded in accordance with the satisfaction of the condition has not been reproduced even after a predetermined time (for example, two days) has elapsed. The recorded data may be deleted from the recorded data storage unit 23. In addition, when recorded data that has been recorded with the satisfaction of the condition is reproduced, the recorded data may be deleted immediately after the reproduction. Furthermore, the contents of the recorded data storage unit 23 may be displayed as a list, and unnecessary data may be deleted by user selection.
(Example 2)

A second embodiment of the present invention will be described below with reference to FIGS.
In the first embodiment described above, “viewing time”, “program information: genre name, program name, etc.” and “CM broadcast” are stored as condition data, and when channel change is instructed. In addition, when these conditions are satisfied, the broadcast program of the channel before the change is recorded, but in the second embodiment, in addition to “viewing time” as the condition data, “viewing time” "Band" is stored, and when these switching conditions are satisfied when a channel switching change is instructed, broadcast programs of channels before and after the change are simultaneously output. Further, in the second embodiment, after the channel change is performed during the CM broadcast, when the end of the CM broadcast is detected by the detection operation for detecting whether the CM broadcast is ended in the channel before the change, It is intended to automatically return to the channel. Here, the same or the same names in both embodiments are denoted by the same reference numerals, the description thereof will be omitted, and the following description will focus on the features of the second embodiment. .

FIG. 11 is a diagram showing the contents of the condition data storage unit 22 in the second embodiment.
The condition data storage unit 22 stores a determination condition for determining whether or not there is a probability of watching the broadcast content of the channel before the change after that when the channel change is instructed. In addition to the “viewing time” as in the first embodiment, “viewing time zone” is stored. This “viewing time zone” is an arbitrary time zone in which the user has a high possibility of watching TV in his daily life. In the example shown in the figure, “19:00 to 21:00” is set. Is the case.

Next, characteristic portions in the second embodiment will be described with reference to the flowcharts shown in FIGS. FIG. 12 is a flowchart detailing the channel switching process in the second embodiment, and FIG. 13 is a flowchart detailing the CM detection process in the second embodiment. Note that when the TV broadcast viewing function is activated and a viewing start instruction is given, the flowchart of FIG. 5 starts to be executed.
Here, when channel switching is instructed, execution of the channel switching process shown in the flowchart of FIG. 12 is started. First, in response to the channel switching operation, the CPU 1 ends the measuring operation of the viewing time timer 24 (step D1), and then starts the television broadcast reception of the changed channel (new channel) (step D2).

 Then, “viewing time” is read from the condition data storage unit 22 and the measured time is acquired from the viewing time timer 24 to check whether the measured time is equal to or greater than “viewing time” (step D3). As a result, if the viewing time is equal to or longer than the storage time, the “viewing time zone” is read from the condition data storage unit 22 and the current time is read from the RTC 17 to check whether the current time belongs to the “viewing time zone”. (Step D4) If it is a viewing time zone, the establishment of a condition is detected.

 If the establishment of the condition is detected in this way, it is checked whether the channel before the change is being broadcasted on the CM (step D5). If not, the broadcast contents for the two channels before and after the change are simultaneously output (step S5). D6) If the CM broadcast is in progress, a “condition establishment flag” is held in the memory 4 in order to suspend simultaneous output for two channels until the CM broadcast ends (step D7). Then, in order to measure the viewing time of the channel after the change, the process proceeds to a viewing time measurement process (step D8), and the viewing time timer 24 in the memory 4 is cleared to start.

FIG. 14 shows a television screen of the second embodiment, which is a television screen when broadcasting for two channels is simultaneously output.
On the main screen M of the television screen, the broadcast video of the channel after the change is displayed and output, and on the sub-screen S, the broadcast video of the channel before the change is displayed and output. That is, the CPU 1 executes a parallel operation of displaying the broadcast video of the channel before the change in parallel with the channel after the change. Note that the audio data of the channel after the change may be output from the built-in speaker 16 and the audio data of the channel before the change may be output from the receiving speaker 7, but the audio output of the channel before the change is prohibited. Alternatively, any one of the audio output methods may be arbitrarily selected by the user.

 In addition, a viewing button BT5 and a switching button BT6 as touch buttons are provided on the television screen. When the television broadcast of the channel after the change is continued to be viewed, the viewing button BT5 is operated, and the original channel (condition) When switching to the matching channel), the switching button BT6 is operated. If the switching button BT6 is operated (YES in step D9), the process returns to the above-described step D1, but if the viewing button BT5 is operated (NO in step D9), the channel switching process is terminated. Return to step A4 in FIG.

 On the other hand, when it is determined as “NO” in any of the above-described condition determination steps D3 and D4, that is, when it is less than the viewing time (NO in step D3) or when it is out of the viewing time zone. (NO in step D4), it is recognized that the condition is not satisfied, and broadcast reception of the channel before the change is terminated (step D10), and broadcast output of the channel after the change is started (step D11). Then, in order to measure the viewing time of the channel after the change, the process proceeds to a viewing time measurement process (step D12), and the viewing time timer 24 in the memory 4 is cleared and started.

Here, when the CM detection timing is reached, execution of the CM detection process shown in the flowchart of FIG. 13 is started.
First, the CPU 1 checks whether or not the CM is being broadcast on the original channel (the channel before the change) (step E1). If the CM is not being broadcast, the CPU 1 exits from the CM detection process, but if the CM is being broadcast, It is checked whether the CM broadcast is finished (step E2). Here, when the end of the CM broadcast is detected, it is checked whether or not the above-mentioned “condition establishment flag” is set (step E3). Similarly, broadcast contents for two channels before and after the change are output simultaneously (step E4).

 Also in this case, as shown in FIG. 14, the broadcast video of the channel after the change is displayed and output on the main screen M of the television screen, and the broadcast video of the channel before the change is displayed and output on the sub-screen S. . Here, when the switching button BT6 is operated (YES in Step E5), the process proceeds to the channel switching process (Step A7 in FIG. 5), and when the viewing button BT5 is operated (NO in Step E5), The channel switching process is exited, and the process returns to step A4 in FIG.

 As described above, in this second embodiment, in addition to “viewing time” as condition data, “viewing time zone” can be stored, and the condition can be set in consideration of the lifestyle of the user. . In addition, when a change of channel is instructed, simultaneous output of the channels before and after the change is started according to the satisfaction of the conditions of “viewing time” and “viewing time zone”. Can be viewed in parallel. In this case, the channel broadcast video after the change is output to the main screen, and the channel broadcast video before the change is displayed on the sub screen.

In the second embodiment described above, the sub-screen is superimposed on the main screen of the TV screen and displayed in combination. However, the TV screen is divided into two, and the broadcast contents before and after the change are displayed in each divided screen. May be displayed in parallel.
In the second embodiment described above, the “viewing time zone” is not limited to a simple time, but may include a day of the week or a date. For example, “Tuesday to Thursday from 19:00 to 21:00” and “Monday and Friday from 22:00 to 23:00” may be stored as the “viewing time zone”. Further, the condition data storage unit 22 may be configured to be able to store a plurality of condition records as in the first embodiment described above.

  In the first and second embodiments described above, the condition data is stored when the television broadcast is received and output. However, the storage timing of this condition data is arbitrary, and the television broadcast can be stored separately from the received output. It is. In addition, if the channel before the change is being broadcast when the condition is satisfied, the recording operation of the program is suspended until the CM broadcast ends, or simultaneous output for two channels is suspended, You may make it start the video recording operation / simultaneous output on hold at the time of completion | finish.

 In the first and second embodiments, a confirmation message is displayed when the CM broadcast ends on the channel before the change, and the viewing button is operated to continue viewing the current channel broadcast, When switching to, the operation of the switch button is requested, but such a confirmation message is not displayed, that is, without requiring a special operation, it automatically returns to the channel before change (original channel) You may make it make it. At this time, the automatic return function may be arbitrarily set on / off.

In the first and second embodiments, two television broadcast receiving tuners 13 and 14 are provided, but the number of tuners may be three or more.
