  According to the first and ninth aspects of the invention, when the received program becomes unviewable, the recording of the unviewable program starts, and when the program becomes viewable, the recorded program is Since the chasing playback is performed, it is possible to prevent the program from being overlooked until the received program becomes viewable.

Embodiments of the present invention will be described below with reference to the drawings.
A. First Embodiment (1) Configuration FIG. 1 is a block diagram showing a configuration of a broadcast receiving apparatus according to a first embodiment of the present invention. In this figure, the tuner 10 selects and receives a digital broadcast signal of channel number CH set by a system controller 15 described later via an antenna ANT. The demodulator 11 performs OFDM demodulation on the digital broadcast signal selected and received by the tuner 10 and outputs a transport stream TS. The demultiplexer 12 separates the transport stream TS output from the demodulator 11 into an AV (video / audio) stream and a data stream.

  The program information processing unit 13 generates an electronic program guide EPG based on the program arrangement information SI constituting the data stream output from the demultiplexer 12, and also viewing restriction data (parental rate) for restricting program viewing by age. It is determined whether or not the (descriptor) is included in the program arrangement information SI, and a viewing restriction detection signal is generated when viewing restriction data is included. The input unit 14 is composed of, for example, a known infrared remote controller, and includes a power switch for instructing on / off of a driving power source, a channel switch for switching a receiving channel, and the like, and generates an event corresponding to the switch operation to the system controller 15. Supply.

  The system controller 15 controls each part of the apparatus according to a switch operation event supplied from the input unit 14 and a viewing restriction detection signal supplied from the program information processing unit 13. For example, when an operation event corresponding to a power-on (or power-off) switch operation is given from the input unit 14, the drive power supply of each unit is set to ON (or OFF setting), an operation event corresponding to a channel switch operation, or an electronic program The channel number CH of the receiving station specified by the channel selection operation using the table EPG is set in the tuner 10.

  The system controller 15 gives operation instructions to the AV decoder 16, the recording / playback unit 17, and the AV output unit 18 in accordance with the viewing restriction detection signal generated by the program information processing unit 13. That is, if the viewing restriction detection signal is not supplied from the program information processing unit 13, that is, if a program that is not subject to viewing restriction is received, the system controller 15 outputs a decoded output to the AV decoder 16. An instruction is given to supply to the AV output unit 18 at the next stage.

  On the other hand, when the viewing restriction detection signal is supplied from the program information processing unit 13, the system controller 15 instructs the AV decoder 16 to temporarily stop decoding output to the AV output unit 18 and perform recording. The playback unit 17 is instructed to start recording. In addition, when the viewing restriction detection signal is supplied from the program information processing unit 13, the system controller 15 instructs the AV output unit 18 to generate a password input screen.

  As will be described later, when password authentication for canceling viewing restriction is performed using the password input screen, the system controller 15 instructs the recording / playback unit 17 to start chasing playback of the recorded content. When the recording / playback unit 17 starts chasing playback, the system controller 15 instructs the AV output unit 18 to display and output the playback output of the recording / playback unit 17. In the system controller 15, when the chasing playback position of the recording / playback unit 17 catches up with the current recording position, or when the reception channel is changed during recording of a program whose viewing is restricted, the recording stop and the playback stop are recorded and played back. The unit 17 is instructed.

  The AV decoder 16 decodes the AV stream supplied from the demultiplexer 12 into video data and audio data (decoded output), and outputs them to the AV output unit 18 and the recording / playback unit 17. The AV decoder 16 temporarily stops decoding output to the AV output unit 18 in accordance with an instruction from the system controller 15. The recording / playback unit 17 follows the instruction of the system controller 15 while recording the video data and audio data output from the AV decoder 16, chasing and playing back the recorded content (time shift playback), and outputting the playback output to the AV output unit. 18 is supplied. For example, when the chasing playback position catches up with the current recording position by fast-forward playback or when the reception channel is changed during recording of a program whose viewing is restricted, the recording / playback unit 17 performs recording according to the instruction of the system controller 15. And stop chasing playback.

  The AV output unit 18 includes various screen data to be displayed on the OSD display plane. When the password input screen is instructed from the system controller 15, the AV output unit 18 uses the password input screen data on the OSD display plane. To display the password input screen. As will be described later, when proper password authentication for canceling viewing restriction is performed using this password input screen, the system controller 15 instructs the recording / playback unit 17 to start chasing playback of the recorded content. It has become.

  In addition, the AV output unit 18 displays and outputs the output (video data and audio data) of either the AV decoder 16 or the recording / reproducing unit 17 according to an instruction from the system controller 15. That is, when the viewing restriction detection signal is not supplied from the program information processing unit 13, the AV output unit 18 displays video based on the video data and audio data output from the AV decoder 16 in accordance with an instruction from the system controller 15. And voice output.

  On the other hand, when the viewing restriction detection signal is supplied, as described above, the system controller 15 instructs the AV decoder 16 to stop decoding output to the AV output unit 18 and also to the recording / playback unit 17. When an appropriate password authentication for instructing the start of recording and subsequently releasing the viewing restriction is performed, the recording / playback unit 17 is instructed to start the chasing playback of the recorded content. When the recording / playback unit 17 performs the chasing playback, the AV output unit 18 displays and outputs the output (video data and audio data) chased and played back by the recording / playback unit 17 in accordance with an instruction from the system controller 15. When the recording / playback unit 17 stops the follow-up playback, the AV output unit 18 displays video and outputs audio based on video data and audio data output from the AV decoder 16 in accordance with instructions from the system controller 15.

(2) Operation Next, the operation of the first embodiment will be described with reference to FIGS. When the main power is turned on in the broadcast receiving apparatus according to the first embodiment, the system controller 15 proceeds to step SA1 of the main routine shown in FIG. 2 and performs initialization to initialize each part of the apparatus. When the initialization is completed, the system controller 15 executes step SA2 and subsequent steps, and controls each part of the apparatus according to an operation event supplied from the input unit 14 or a viewing restriction detection signal supplied from the program information processing unit 13.

  First, in step SA2, the process waits until an event corresponding to the power switch on operation is supplied from the input unit 14. When an event corresponding to the power switch on operation is supplied from the input unit 14, the determination result here is “YES”, the process proceeds to step SA3, the flag ONF is set to “1”, and the device drive state It represents that. In step SA4, each part of the apparatus is instructed to turn on the power. In subsequent step SA5, the channel number stored in the register CH is set in the tuner 10. As a result, the tuner 10 receives a channel number CH broadcast.

  Next, in step SA6, it is determined whether an event corresponding to the power switch off operation is supplied from the input unit 14. Here, when an event corresponding to the power switch-off operation is supplied from the input unit 14, the determination result becomes “YES”, the process proceeds to Step SA7, the flag ONF is reset to zero, and then the power is supplied to each part of the apparatus in Step SA8. An instruction to turn off is issued, and the process returns to step SA2. Thereafter, the apparatus enters a standby state until an event corresponding to the power switch on operation is supplied from the input unit 14.

  When the event corresponding to the power switch-off operation is not supplied from the input unit 14, the determination result of step SA6 is “NO”, and the process proceeds to step SA9 shown in FIG. In step SA9, it is determined whether or not a channel change event corresponding to the channel switch operation is supplied from the input unit 14. If the channel change event is not supplied from the input unit 14, the determination result here is “NO”, and the process proceeds to Step SA19 shown in FIG. In step SA19, it is determined whether or not the playback flag PF is “1”, that is, whether or not the recording / playback unit 17 has been instructed to start playback. If the flag PF is “0”, that is, if the recording / playback unit 17 is stopped, the determination result is “NO”, and the process proceeds to step SA23 (see FIG. 5) described later.

  On the other hand, when a channel change event corresponding to the channel switch operation is supplied from the input unit 14 in step SA9 (see FIG. 3), the determination result is “YES”, and the flow proceeds to step SA10. In step SA10, as in step SA19 (see FIG. 4) described above, it is determined whether or not the flag PF is “1”. If the flag PF is “0” (the recording / playback unit 17 is stopped), the determination result is “NO”, and the process proceeds to step SA14.

  In steps SA14 to SA15, a viewing restriction detection flag LF indicating whether or not a viewing-restricted program has been detected is reset to zero to indicate that it is in an undetected state, and viewing restriction of the viewing-restricted program is released. The authentication flag VF indicating whether or not the password authentication has been completed is reset to zero to indicate that it has not been authenticated. Next, in step SA16, the channel number stored in the register CH is saved in the register CHB as the channel number received before the channel change. In step SA17, the new channel number changed by the channel switch operation is stored in the register CH. In the subsequent step SA18, the channel number stored in the register CH is set in the tuner 10. As a result, the tuner 10 selects and receives the broadcast of the changed channel number CH.

  Thereafter, the system controller 15 proceeds to step SA23 shown in FIG. 5 and determines whether or not the authentication flag VF is “0”. If password authentication for releasing the viewing restriction has already been performed, the authentication flag VF is “1”, so that the determination result is “NO”, and the process proceeds to step SA6 (see FIG. 2) described above. To return.

  On the other hand, if password authentication for canceling the viewing restriction has not been performed, the determination result in step SA23 is “YES”, and the flow proceeds to step SA24. In step SA24, the program information processing unit 13 determines whether or not the viewing restriction detection signal is generated by detecting the viewing restriction data from the program arrangement information SI. That is, it is determined whether or not a viewing-restricted program is received. If the viewing-restricted program has not been received, the determination result is “NO”, and the process returns to step SA6 (see FIG. 2) described above.

  On the other hand, when a viewing-restricted program is received, the determination result in step SA24 is “YES”, and the flow proceeds to step SA25. In step SA25, it is determined whether or not the viewing restriction detection flag LF is “0”, that is, whether or not the viewing restricted program is received for the first time. If the viewing restriction detection flag LF is set to “1” and a program for which viewing is restricted is already received, the determination result is “NO”, and the process proceeds to step SA32 (see FIG. 6) described later. Proceed.

  On the other hand, if the program for which viewing is restricted is received for the first time, the determination result in step SA25 is “YES”, the process proceeds to step SA26, and the viewing restriction detection flag LF is set to “1”. Next, in step SA27, the AV decoder 16 is instructed to temporarily stop decoding output to the AV output unit 18. In step SA28, “1” is set in the recording flag RF. In step SA29, the recording / playback unit 17 is instructed to start recording. Thus, when a viewing-restricted program is received, video display and audio output of the program are automatically stopped and recording of the program is started at the same time.

  In step SA30, the AV output unit 18 is instructed to generate a password input screen. As a result, the AV output unit 18 displays the password input screen of the example shown in FIG. 9, for example, on the OSD display plane using the password input screen data provided by itself. Next, in step SA31, after instructing the timer that measures the password input waiting time to start counting, the process returns to step SA6 (see FIG. 2).

  Then, when the process proceeds to step SA25 (see FIG. 5) in a state where the viewing-restricted program is received, the viewing restriction detection flag LF is set to “1” in this case, so the determination result is “ "NO", the process proceeds to step SA32 shown in FIG. In step SA32, it is determined whether or not the timer is full count, that is, whether or not the password input waiting time is up after a certain time has elapsed.

  If the time is up, the determination result in step SA32 is “YES”, the process proceeds to step SA33, and the channel number before the channel change saved in the register CHB is stored in the register CH. Next, in step SA34, the channel number stored in the register CH is set in the tuner 10. As a result, when the password is not entered within the password input waiting time and the time is up, the channel is changed to the channel before receiving the viewing-restricted program.

  Thereafter, the process proceeds to step SA41, and the viewing restriction detection flag LF is reset to zero as the channel is changed to the channel before receiving the viewing restricted program. In step SA42, the AV output unit 18 is instructed to delete the password input screen. In step SA43, the AV decoder 16 is instructed to resume decoding output to the AV output unit 18, and then the process returns to step SA6 (see FIG. 2). Thereby, it returns to the reception state before receiving the viewing-restricted program.

  On the other hand, if the password is input before the time is up, the determination result in step SA32 is “NO”, and the flow proceeds to step SA35. In step SA35, it is determined whether or not the input password represents “cancel”. In the example password input screen illustrated in FIG. 9, when “0000” is input in the password input area PIA, it is considered that the password input is cancelled. When such a cancel input is performed, the determination result in step SA35 is “YES”, and the above-described step SA33 and subsequent steps are executed to return to the reception state before receiving the viewing-restricted program.

  On the other hand, if the cancel input is not made, the determination result in step SA35 is “NO”, and the process proceeds to step SA36 to determine whether or not an appropriate password has been input. Here, for example, if an inappropriate password is input, such as an input key operation inappropriate as a password or a lack of input digits, the determination result is “NO”, and the process returns to step SA6 (see FIG. 2). On the other hand, if an appropriate password is entered, the determination result is “YES”, and the flow proceeds to step SA37 to perform password authentication. If the passwords do not match, the determination result here is “NO”, and the above-described step SA33 and subsequent steps are executed to return to the reception state before receiving the viewing-restricted program. If the passwords match, the determination result is “YES”, and the flow proceeds to step SA38.

  In steps SA38 to SA39, “1” is set in each of the authentication flag VF and the regeneration flag PF. In step SA40, the recording / playback unit 17 is instructed to start chasing playback of the recorded content. Next, in step SA41, the viewing restriction detection flag LF is reset to zero. In subsequent steps SA42 to SA43, the AV output unit 18 is instructed to delete the password input screen, and the chasing playback output (video data and audio) of the recording / playback unit 17 is given. After the AV output unit 18 is instructed to display video and output data), the process returns to step SA6 (see FIG. 2). As a result, since the password input screen is displayed on the OSD, that is, the program content from the start of receiving the viewing-restricted program until the password authentication for releasing the viewing restriction is completed can be viewed by chasing playback. , It is possible to prevent a program from being missed during OSD display.

  Now, if the channel is not changed in the state where the program contents during the period when the password input screen is displayed on the OSD is being chased and reproduced, the determination result of the above-described step SA9 (see FIG. 3) becomes “NO”. Proceeding to step SA19 shown in FIG. 4, it is determined whether or not the regeneration flag PF is “1”. Since the reproduction flag PF is “1” when the follow-up reproduction is being performed, the determination result here is “YES”, and the process proceeds to Step SA20. In step SA20, it is determined whether or not the playback position and the recording position match, that is, whether or not the chasing playback position has caught up with the current recording position. If the current recording position has not been caught up, the determination result is “NO”, and the process proceeds to step SA23 (see FIG. 5). On the other hand, for example, when the chasing playback position catches up with the current recording position by fast-forward playback, the determination result of step SA20 is “YES”, and the process proceeds to step SA21.

  When the playback stop process is executed via step SA21, the system controller 15 advances the process to step SB1 shown in FIG. 7, and instructs the recording / playback unit 17 to stop the follow-up playback. Next, in step SB2, the AV output unit 18 is instructed to display and output audio based on the received content (video data and audio data) output from the AV decoder 16. Then, the process proceeds to step SB3, after the regeneration flag PF is reset to zero, the process proceeds to step SA22 shown in FIG.

  When the recording stop process is executed via step SA22, the system controller 15 advances the process to step SC1 shown in FIG. 8 to instruct the recording / playback unit 17 to stop recording, and in the subsequent step SC2, the recording is performed so far. The recording / playback unit 17 is instructed to delete the recorded content. Then, the process proceeds to Step SC3, and after the recording flag RF is reset to zero, the process proceeds to Step SA23 (see FIG. 5) described above.

  On the other hand, if the channel is changed while the program content during the period when the password input screen is displayed on the OSD is being followed and reproduced, the determination result in step SA9 (see FIG. 3) described above becomes “YES”, and step SA10. Then, it is determined whether or not the regeneration flag PF is “1”. If the follow-up reproduction is being performed, the reproduction flag PF is “1”, so the determination result here is “YES”, and the flow proceeds to Step SA11.

  When the playback stop process is executed via step SA11, the system controller 15 advances the process to step SB1 shown in FIG. 7, and instructs the recording / playback unit 17 to stop the follow-up playback. Next, in step SB2, the AV output unit 18 is instructed to display and output audio based on the received content (video data and audio data) output from the AV decoder 16. Then, the process proceeds to step SB3, and after resetting the regeneration flag PF to zero, the process proceeds to step SA12 shown in FIG.

  In step SA12, it is determined whether or not the recording flag RF is “1”. If recording is in progress, the determination result is “YES”, and the flow proceeds to step SA13. When the playback stop process is executed via step SA13, the system controller 15 advances the process to step SC1 shown in FIG. 8, and instructs the recording / playback unit 17 to stop recording. The recording / playback unit 17 is instructed to delete the recorded content. Then, the process proceeds to step SC3, and after the recording flag RF is reset to zero, the above-described step SA14 and subsequent steps are executed to select and receive the broadcast of the changed channel number CH.

  As described above, in the first embodiment, when the program information processing unit 13 detects that the viewing restriction data is included in the received broadcast program arrangement information SI, the system controller 15 displays the viewing restricted program. The recording / playback unit 17 is instructed to display the password input screen for releasing the viewing restriction. When password authentication using the password input screen is completed, the recorded program content starts to be chased and played back, and when the playback position catches up with the recording position, chasing playback and recording are stopped, so viewing is restricted. From the start of receiving the program until the password authentication for releasing the viewing restriction is completed, that is, it is possible to prevent the program from being overlooked during OSD display.

B. Second Embodiment In the first embodiment described above, it is possible to prevent a program from being overlooked during the period from the start of receiving a view-restricted program until password authentication for releasing the view restriction is completed. Then, for example, program oversight while various function operations such as an operation for displaying the electronic program guide EPG is performed is prevented. Since the configuration of the second embodiment is common to the first embodiment, the description thereof is omitted. The operation of the second embodiment will be described below with reference to FIGS.

  When the main power supply is turned on to the broadcast receiving apparatus according to the second embodiment, the system controller 15 proceeds to step SD1 of the main routine shown in FIG. 10 and performs initialization to initialize each part of the apparatus. When the initialization is completed, the system controller 15 executes step SD2 and subsequent steps, and controls each part of the apparatus according to an operation event supplied from the input unit 14.

  First, in step SD2, the process waits until an event corresponding to the power switch on operation is supplied from the input unit 14. When an event corresponding to the power switch-on operation is supplied from the input unit 14, the determination result here is “YES”, the process proceeds to step SD3, the flag ONF is set to “1”, and the device drive state It represents that. Next, in step SD4, each part of the apparatus is instructed to turn on the power. In subsequent step SD5, the channel number stored in the register CH is set in the tuner 10. As a result, the tuner 10 receives a channel number CH broadcast.

  Next, in step SD6, it is determined whether or not an event corresponding to the power switch off operation is supplied from the input unit 14. Here, when an event corresponding to the power switch-off operation is supplied from the input unit 14, the determination result is “YES”, the process proceeds to step SD7, the flag ONF is reset to zero, and then power is supplied to each part of the apparatus in step SD8. An instruction to turn off is issued, and the process returns to step SD2. Thereafter, the apparatus enters a standby state until an event corresponding to the power switch on operation is supplied from the input unit 14.

  If an event corresponding to the power switch-off operation is not supplied from the input unit 14, the determination result in step SD6 is “NO”, and the flow proceeds to step SD9 shown in FIG. In step SD9, it is determined whether or not a channel change event corresponding to the channel switch operation is supplied from the input unit 14. If the channel change event is not supplied from the input unit 14, the determination result here is “NO”, and the process proceeds to step SD16 shown in FIG. In step SD16, it is determined whether or not the playback flag PF is “1”, that is, whether or not the recording / playback unit 17 has been instructed to start playback. If the flag PF is “0”, that is, if the recording / playback unit 17 is stopped, the determination result is “NO”, and the process proceeds to step SD20 (see FIG. 13) described later.

  On the other hand, when a channel change event corresponding to the channel switch operation is supplied from the input unit 14 in step SD9 (see FIG. 11), the determination result is “YES”, and the flow proceeds to step SD10. In step SD10, it is determined whether or not the flag PF is “1” as in step SD16 (see FIG. 12). If the flag PF is “0” (the recording / playback unit 17 is stopped), the determination result is “NO”, and the process proceeds to step SD14. In step SD14, the new channel number changed by the channel switch operation is stored in the register CH, and in step SD15, the channel number stored in the register CH is set in the tuner 10. As a result, the tuner 10 selects and receives the broadcast of the changed channel number CH.

  Thereafter, the system controller 15 advances the process to step SD20 shown in FIG. 13, and determines whether there is a pop-up instruction. The pop-up instruction is an instruction for popping up a user input screen for calling various function screens such as an electronic program guide EPG. If there is no popup instruction, the determination result here is “NO”, and the process returns to step SD6 (see FIG. 10).

  On the other hand, if there is a pop-up instruction, the determination result in step SD20 is “YES”, and the flow proceeds to step SD21. In step SD21, it is determined whether the recording flag RF is “0”, that is, whether recording is stopped. If the recording is stopped, the determination result is “YES”, the process proceeds to step SD22, and the recording flag RF is set to “1”. In step SD23, the recording / playback unit 17 is instructed to start recording. As a result, in response to the pop-up instruction, the recording / playback unit 17 starts recording the program being received.

  Next, in step SD24, the AV output unit 18 is instructed to generate a user input screen for calling various functions such as displaying the electronic program guide EPG on the screen. As a result, the AV output unit 18 causes the user input screen to be pop-up displayed on the OSD display plane using the user input screen data provided by itself. Next, in step SD25, the timer for measuring the user input waiting time is instructed to start counting, and then the process returns to step SD6 (see FIG. 10).

  Then, when the process proceeds to the above-described step SD21 (see FIG. 13) while the user input screen is displayed, since the recording flag RF is set to “1”, the determination result is “NO”, and FIG. The process proceeds to the illustrated step SD26. In step SD26, it is determined whether or not the timer is full count, that is, whether or not the user input waiting time is up after a certain time has elapsed. If time is up, the determination result in step SD26 is “YES”, and the flow proceeds to step SD28 described later.

  On the other hand, if a user input is made before the time is up, the determination result in step SD26 is “NO”, and the flow proceeds to step SD27. In step SD27, it is determined whether or not the user input has been completed. The user input here refers to an operation of selecting a predetermined function on the user input screen. If such user input is not completed, the determination result is “NO”, and the process returns to step SD6 (see FIG. 10). However, when the user input is completed, the determination result is “YES”. In step SD28, the AV output unit 18 is instructed to erase the user input screen. In step SD29, the AV output unit 18 is instructed to generate a selection screen that allows the user to select either “live viewing” or “time shift playback”.

  Next, in step SD30, it is determined whether or not “time shift reproduction” is selected on the selection screen. When “live viewing” is selected on the selection screen, the determination result is “NO”, the process proceeds to step SD33, and the AV output unit 18 is instructed to erase the selection screen. 10)).

  On the other hand, when “time shift reproduction” is selected on the selection screen, the determination result in step SD30 is “YES”, and the flow proceeds to step SD31. In step SD31, the playback flag PF is set to “1”, and in the subsequent step SD32, the recording / playback unit 17 is instructed to start chasing playback of the recorded content. In step SD33, the AV output unit 18 is instructed to erase the selection screen, and then the process returns to step SD6 (see FIG. 10). As a result, the contents of the program can be viewed by chasing playback (time cyst playback) while the user input screen or the selection screen is displayed on the OSD according to the pop-up instruction, so that it is possible to prevent the program from being overlooked during OSD display. It is possible.

  If the channel is not changed while viewing the contents of the program being displayed on the OSD by time-shifted playback (chasing playback), the determination result in step SD9 (see FIG. 11) is “NO”. Proceeding to step SD16 shown in FIG. 12, it is determined whether or not the regeneration flag PF is “1”. When the follow-up reproduction is being performed, the reproduction flag PF is “1”, so that the determination result here is “YES”, and the process proceeds to step SD17. In step SD17, it is determined whether or not the playback position matches the recording position, that is, whether or not the chasing playback position has caught up with the current recording position. If the current recording position is not caught up, the determination result is “NO”, and the process proceeds to step SD20 (see FIG. 13). On the other hand, for example, when the chasing playback position catches up with the current recording position by fast-forward playback, the determination result in step SD17 is “YES”, and the process proceeds to step SD18.

  When the playback stop process is executed via step SD18, the system controller 15 proceeds to step SB1 shown in FIG. 7 and instructs the recording / playback unit 17 to stop the follow-up playback, as in the first embodiment. . Next, in step SB2, the AV output unit 18 is instructed to display and output audio based on the received content (video data and audio data) output from the AV decoder 16. Then, the process proceeds to step SB3, after the regeneration flag PF is reset to zero, the process proceeds to step SD19 shown in FIG.

  When the recording stop process is executed via step SD19, the system controller 15 advances the process to step SC1 shown in FIG. 8 and instructs the recording / playback unit 17 to stop the recording, as in the first embodiment. In step SC2, the recording / playback unit 17 is instructed to delete the contents recorded so far. Then, the process proceeds to step SC3, and after the recording flag RF is reset to zero, the process proceeds to step SD20 (see FIG. 13).

  On the other hand, when the channel is changed while viewing the contents of the program being displayed on the OSD by time-shifted playback, the determination result in step SD9 (see FIG. 11) becomes “YES”, and the process proceeds to step SD10. It is determined whether or not the reproduction flag PF is “1”. If the follow-up reproduction is being performed, the reproduction flag PF is “1”, so the determination result here is “YES”, and the process proceeds to step SD11.

  When the playback stop process is executed via step SD11, the system controller 15 proceeds to step SB1 shown in FIG. 7 and instructs the recording / playback unit 17 to stop the follow-up playback, as in the first embodiment. . Next, in step SB2, the AV output unit 18 is instructed to display and output audio based on the received content (video data and audio data) output from the AV decoder 16. In step SB3, the regeneration flag PF is reset to zero, and then the process proceeds to step SD12 shown in FIG.

  In step SD12, it is determined whether or not the recording flag RF is “1”. If recording is in progress, the determination result is “YES”, and the flow proceeds to step SD13. When the playback stop process is executed via step SD13, the system controller 15 advances the process to step SC1 shown in FIG. 8 and instructs the recording / playback unit 17 to stop recording, as in the first embodiment. In step SC2, the recording / playback unit 17 is instructed to delete the contents recorded so far. Then, the process proceeds to step SC3, and after the recording flag RF is reset to zero, the above-described step SD14 and subsequent steps are executed to select and receive the broadcast of the changed channel number CH.

  As described above, in the second embodiment, when there is a pop-up instruction for calling various function screens such as the electronic program guide EPG, the system controller 15 instructs the recording / playback unit 17 to start recording the received program. When the user selects time shift playback, the recorded program contents are chased and played back while the operation screen is displayed in OSD according to the pop-up instruction, and the chasing playback and recording are performed when the playback position catches up with the recording position. Since the program is stopped, it is possible to prevent a program from being overlooked during OSD display.
