The various control programs include a playback process, a fast-forward process, a fast-rewind process, a skip process, and an overlap recording process, which will be described later, executed by the control unit 2. 4 is a tuner that receives and demodulates a broadcast signal of a broadcast station designated by the control unit 2 in accordance with a channel selection command among broadcast signals input via an antenna ANT, and then demultiplexes and generates a video / audio signal. . Reference numeral 5 denotes an encoder that generates video / audio data obtained by compression-coding the video / audio signal output from the tuner 4 using the MPEG method.

  A hard disk device 6 performs a recording / reproducing operation in accordance with a recording command and a reproducing command from the control unit 2. As shown in FIG. 2, the hard disk device 6 includes a recording medium M including a system area SYS, a recording reservation data area RRA, various setting data areas SDA, and a recording data area RDA. Recording data RD of a plurality of programs 1 to N is stored in the recording data area RDA. The recorded data RD includes program information, operation information, and video / audio data. The program information represents a title name, recording date / time, recording time, and recording mode. The operation information is information that represents the history of each operation that the user changed the playback volume, set the screen, fast-forwarded, and fast-rewinded to set the viewing environment of his / her preference when the recorded program was played (viewed) for the first time. Yes, it is formed from a viewed flag F, volume data VOL, screen setting data DSD, fast forward data FWD, and fast reverse data FRD.

  Here, the contents of the viewed flag F, volume data VOL, screen setting data DSD, fast forward data FWD, and fast reverse data FRD will be described with reference to FIG. The viewing completed flag F is a flag indicating whether or not the corresponding recorded data RD has been viewed (reproduced), and is “0” if not viewed (unreproduced), and “1” when the first reproduction is completed. . The volume data VOL is composed of a volume level representing a history of volume operations performed by the user when the recorded data RD is reproduced for the first time, and a change time. The screen setting data DSD is composed of screen setting information indicating a history of screen setting operations performed by the user at the first playback of the recording data RD and a change time. The screen setting information is information representing the setting contents of brightness, contrast, and image quality. The fast-forward data FWD is composed of a fast-forward operation performed by the user at the first playback of the recorded data RD, for example, a fast-forward start time and a feed time (fast-forward period) representing a history of fast-forwarding the CM portion of the recorded data RD. The fast-rewind data FRD is a fast-rewind operation performed by the user when the recorded data RD is reproduced for the first time, for example, a fast-rewind start time and a return time indicating a history of fast-rewind when a predetermined part of the recorded data RD is viewed repeatedly (fast-rewind period). ).

  Next, the configuration of the embodiment will be described with reference to FIG. 1 again. The hard disk device 6 that performs medium recording with the above-described data structure is configured to be able to simultaneously execute recording / reproduction. When recording a program, the hard disk device 6 records the compression-coded video / audio data output from the encoder 5 as recording data RD for each program according to a recording instruction given from the control unit 2. When the recorded data RD of the recorded program is reproduced for the first time, the recorded data RD designated by the reproduction instruction given from the control unit 2 is read out from the recording medium M and output to the decoder 8, while the user performs the reproduction during the reproduction. Operation information representing a series of operations performed to set a viewing environment of his / her preference is recorded in association with the recorded data RD being reproduced. The operation information is generated by the control unit 2 based on the operation command supplied from the operation unit 1 and temporarily stored in the RAM 7. The control unit 2 reads out the RAM 7 from the RAM 7 when the first reproduction of the recorded data RD is completed. The hard disk device 6 is instructed to record in association with the recording data RD.

  When playing back the recorded data RD to which the operation information is given (playback after the second time), the control unit 2 creates the playback table RT and the control table CT based on the operation information read out by the hard disk device 6 before playing back the recorded data RD. Created and stored in RAM 7. As shown in FIG. 4, the reproduction table RT instructs an event time indicating a fast-forward or fast-reverse execution timing and a fast-forward operation or a fast-rewind operation based on the fast-forward data FWD and the fast-rewind data FRD in the operation information. It is a table in which events are arranged in chronological order. Although not shown, the control table CT is similar to the reproduction table RT, based on the volume data VOL and the screen setting data DSD in the operation information, the event time indicating the execution timing of the volume change or the screen setting change, the volume change or It is the table which arranged the event which instruct | indicates a screen setting change in time series order. The control unit 2 refers to the reproduction table RT stored in the RAM 7 and instructs the hard disk device 6 to reproduce the recorded data RD. Further, the control unit 2 refers to the control table CT stored in the RAM 7 and generates a volume control signal and a screen setting signal.

  In FIG. 1, a decoder 8 expands and outputs recorded data RD (compressed video / audio data) that is reproduced and output by the hard disk device 6 in accordance with a reproduction instruction from the control unit 2. Reference numeral 9 denotes a video / audio output unit. The video / audio output unit 9 converts the video / audio data supplied from the decoder 8 into an analog video signal and audio signal, and supplies the converted video signal to the video input terminal of the monitor 10 and is converted. The audio signal is level-controlled according to the volume control signal output from the control unit 2 and supplied to the audio input terminal of the monitor 10. The video / audio output unit 9 generates a screen control signal for controlling the brightness, contrast, and image quality of the monitor 10 in accordance with the screen setting signal output from the control unit 2. The monitor 10 reproduces video and audio with luminance, contrast, and image quality set according to the screen control signal supplied from the video / audio output unit 9.

B. Operation Next, the operation of the control unit 2 according to the gist of the present invention will be described with reference to FIGS. Hereinafter, the description will be divided into an operation when the control unit 2 reproduces the recorded data RD for the first time and an operation when the reproduction is performed for the second time and thereafter.

(1) First Playback Operation When the user operates the remote controller 1a to play back the recorded data RD recorded in the hard disk device 6 for the first time, the control unit 2 generates a playback command and sends it to the hard disk device 6. The hard disk device 6 reads out operation information given to the recorded data RD prior to the reproduction of the recorded data RD and sends it to the control unit 2. The control unit 2 determines whether or not the first playback is based on the viewed flag F in the operation information. If the viewed flag F is “0”, the control unit 2 determines that the playback is the first time, and executes the playback process shown in FIG. When the playback process is executed, the control unit 2 proceeds to step SA1, resets the time counter, and in the subsequent step SA2, instructs the hard disk device 6 to start playback of the recorded data RD. The time counter is counted by a timer interrupt process (not shown).

  Next, in steps SA3 to SA6, it is determined whether or not the user has performed an operation (volume change, screen setting, fast forward and fast reverse operations) for setting his / her favorite viewing environment during reproduction of the recorded data RD. If these operations are not performed, the determination results in steps SA3 to SA6 are “NO”, and the process proceeds to step SA7 to determine whether there is a stop command. When a stop command is generated by a user operation, the determination result is “YES”, and this process is completed. If the stop command is not generated, the determination result is “NO”, the process proceeds to step SA8, and it is determined whether there is a reproduction end command. When a reproduction end command is generated by a user operation, the determination result is “YES”, the process proceeds to step SA9, the viewed flag F is set to “1”, and stored in the RAM 7. If the playback stop command does not occur, the determination result is “NO”, and the process returns to step SA3.

  On the other hand, when the user performs any operation of changing the volume, setting the screen, fast-forwarding, and fast-rewinding during the reproduction of the recorded data RD, a process of storing the history of the operation in the RAM 7 as operation information is performed. Hereinafter, the operation will be described separately for the case where the volume changing operation, the screen setting operation, the fast forward operation, and the fast reverse operation are performed.

a. When Volume Change Operation is Performed In this case, the determination result in step SA3 is “YES”, the process proceeds to step SA10, and the volume data VOL including the volume level and change time indicating the history of volume operation is stored in the RAM 7, and then step SA3. Return processing to.

b. In the case where the screen setting operation is performed In this case, after the determination result in step SA4 is “YES”, the process proceeds to step SA11, and after the screen setting data DSD including the screen setting information indicating the history of the screen setting operation and the change time is stored in the RAM 7 The process returns to step SA3.

c. In this case, the determination result in step SA5 is “YES”, and the fast-forward process shown in FIG. 6 is executed. When the fast-forward process is executed, the control unit 2 proceeds to step SB1 in FIG. 6 and stores the fast-forward start time in the RAM 7. Next, in step SB2, the fast-forward time counter is reset. The fast-forwarding time counter is counted by a timer interrupt process (not shown). Subsequently, in steps SB3 to SB8, it is determined whether or not a user operation (volume change, screen setting, fast reverse, playback, playback stop, and playback end) is performed during the fast forward period. If these operations are not performed, steps SB3 to SB8 are repeated.

When the volume change operation is performed, the determination result in step SB3 is “YES”, and the process proceeds to step SB9, where the volume data VOL including the volume level and the change time indicating the history of volume operation is stored in the RAM 7, and then step SB3. Return processing to.
If a screen setting operation has been performed, the determination result in step SB4 is “YES”, and the process proceeds to step SB10, where screen setting data DSD indicating the history of the screen setting operation and the change time are stored in the RAM 7. Then, the process returns to step SB3.

When the fast reverse operation is performed, the determination result in step SB5 is “YES”, and the process proceeds to step SB11. In step SB11, fast-forwarding is stopped and the value of the fast-forwarding time counter at that time, that is, the feeding time is stored in the RAM 7. Thereby, fast-forward data FWD composed of the fast-forward start time and the feed time is formed. Thereafter, a fast-forward process (described later) shown in FIG. 7 is executed.
When the reproduction operation is performed, the determination result in step SB6 is “YES”, and the process proceeds to step SB12. In step SB12, fast-forwarding is stopped and the value of the fast-forwarding time counter at that time, that is, the feeding time is stored in the RAM 7. Thereby, fast-forward data FWD composed of the fast-forward start time and the feed time is formed. Thereafter, the process proceeds to step SA2 of the reproduction process illustrated in FIG.

When the reproduction stop operation is performed, the determination result in step SB7 is “YES”, and the process proceeds to step SB13. In step SB13, the fast-forwarding is stopped, the value of the fast-forwarding time counter at that time is stored in the RAM 7 to form the fast-forwarding data FWD, and then the end code is stored in the RAM 7 following the fast-forwarding data FWD, and the process is finished. .
When the reproduction end operation is performed, the determination result in step SB8 is “YES”, and the process proceeds to step SB13. As in the reproduction stop operation, the value of the fast forward time counter (feed time) at the time when the fast forward is stopped and The end code is stored in the RAM 7 and this process is finished.

d. When a fast-rewind operation is performed If a fast-rewind operation is performed during the reproduction process, the determination result in step SA5 shown in FIG. 5 is “YES”, and the fast-rewind process shown in FIG. 7 is executed. If a fast-rewind operation is performed during the fast-forward process, the fast-rewind process shown in FIG. 7 is executed through step SB11 shown in FIG. When the fast reverse process is executed, the control unit 2 proceeds to step SC1 in FIG. 7 and stores the fast reverse start time in the RAM 7. Next, in step SC2, the fast reverse time counter is reset. The fast return time counter is counted by timer interrupt processing (not shown). Subsequently, in steps SC3 to SC8, it is determined whether or not there is a user operation (volume change, screen setting, fast forward, playback, playback stop, and playback end operations) performed during the fast reverse period. If these operations are not performed, steps SC3 to SC8 are repeated.

If the volume change operation is performed, the determination result in step SC3 is “YES”, and the process proceeds to step SC9, where the volume data VOL including the volume level and change time representing the volume operation history is stored in the RAM 7, and then step SC3. Return processing to.
If the screen setting operation is performed, the determination result in step SC4 is “YES”, and the process proceeds to step SC10. After screen setting information DSD indicating the history of the screen setting operation and the change time are stored in the RAM 7, Return the process to step SC3.

When the fast-forward operation is performed, the determination result in step SC5 is “YES”, and the process proceeds to step SC11. In step SC11, the fast return is stopped, and the value of the fast return time counter at that time, that is, the return time is stored in the RAM 7. As a result, the fast return data FRD including the fast return start time and the return time is formed. Thereafter, the fast-forward process shown in FIG. 6 is executed.
When the reproduction operation is performed, the determination result in step SC6 is “YES”, and the process proceeds to step SC12. In step SC12, the fast return is stopped, and the value of the fast return time counter at that time, that is, the return time is stored in the RAM 7. As a result, the fast return data FRD including the fast return start time and the return time is formed. Thereafter, the process proceeds to step SA2 of the reproduction process illustrated in FIG.

When the reproduction stop operation is performed, the determination result in step SC7 is “YES”, and the process proceeds to step SC13. In step SC13, fast rewinding is stopped, the value of the fast rewinding time counter at that time is stored in the RAM 7, and the fast rewinding data FRD composed of the fast rewinding start time and the rewinding time stored earlier is formed. Following the return data FRD, an end code is stored in the RAM 7 and the present process is terminated.
When the reproduction end operation is performed, the determination result in step SC8 is “YES”, and the process proceeds to step SB13, and the value of the fast reverse time counter (return time) at the time when the fast reverse is stopped is the same as in the reproduction stop operation. ) And the end code are stored in the RAM 7 and the process is terminated.

  As described above, when the recorded data RD of the recorded program is reproduced for the first time, if the user performs various operations to set the viewing environment of his / her preference during the reproduction, the operation unit 1 responds to these operations. Based on the generated operation command, the control unit 2 generates operation information and temporarily stores it in the RAM 7. Then, when the first playback of the recorded data RD is completed, the control unit 2 reads the operation information temporarily stored in the RAM 7 and instructs the hard disk device 6 to record it in association with the corresponding recorded data RD. Accordingly, operation information representing a history of a series of operations performed by the user to set his / her favorite viewing environment when the recorded data RD is reproduced for the first time is given to the recorded data RD.

(2) Second and subsequent reproduction operations Next, the second and subsequent reproduction operations for reproducing the recorded data RD to which operation information representing a series of operation histories is given will be described. When the user operates the remote controller 1 a to reproduce the recorded data RD, the control unit 2 generates a reproduction command and sends it to the hard disk device 6. The hard disk device 6 reads out operation information given to the recorded data RD prior to the reproduction of the recorded data RD and sends it to the control unit 2. The control unit 2 determines whether or not the first playback is based on the viewed flag F in the operation information. If the watched flag F is “1”, the control unit 2 assumes that the reproduction is performed for the second time or later, and executes the reproduction process shown in FIG. When the reproduction process is executed, the control unit 2 proceeds to step SD1.

  In step SD1, a reproduction table RT (see FIG. 4) and a control table CT are created and stored in the RAM 7 based on operation information read by the hard disk device 6 prior to reproduction of the recorded data RD. Next, in step SD2, the time counter is reset. The time counter is counted by timer interrupt processing (not shown). Subsequently, in step SD3, the hard disk device 6 is instructed to start reproduction of the recorded data RD. In steps SD4 to SD7, execution of processing corresponding to an event registered in the reproduction table RT and the control table CT is instructed until the user performs a reproduction end operation.

That is, when the event time indicating the execution timing of the screen setting change registered in the control table CT coincides with the time count value and reaches the screen setting change time, the determination result in step SD4 becomes “YES”, and step SD8. Proceed to In step SD8, a screen setting signal corresponding to the corresponding screen setting change event in the control table CT is generated and sent to the video / audio output unit 9. As a result, the video / audio output unit 9 changes the screen setting of the monitor 10 by generating a screen control signal for controlling the brightness, contrast, and image quality according to the screen setting signal output from the control unit 2.
When the event time indicating the execution timing of the volume change registered in the control table CT coincides with the time count value and reaches the volume change time, the determination result in step SD5 is “YES”, and the process proceeds to step SD9. In step SD9, a volume control signal corresponding to the corresponding volume setting change event in the control table CT is generated and sent to the video / audio output unit 9. Accordingly, the video / audio output unit 9 outputs an audio signal whose level is controlled according to the volume control signal to the monitor 10.

  If the event time indicating the fast-forward (or fast-reverse) execution timing registered in the reproduction table RT matches the time count value and reaches the fast-forward event (or fast-rewind event), the determination result in step SD6 is It becomes "YES" and progresses to step SD10. In step SD10, the hard disk device 6 is instructed to skip when the fast forward event (or fast reverse event) is completed. As a result, the hard disk device 6 skips the portion of the recording data RD that has been fast-forwarded (or fast-rewinded) during the first playback in accordance with the skip instruction of the control unit 2 and starts playback from the fast-forward (or fast-rewind) destination.

  Thus, in the second and subsequent playback operations, the operation information given to the recorded data RD is read prior to the playback of the recorded data RD, and the playback table RT and the control table CT created based on the read operation information are read out. Referencing, changing the playback volume and screen settings, skipping the part that was fast-forwarded (or the part that was fast-rewinded) during the first playback, and starting playback from the fast-forward destination (or fast-rewind destination) It is possible to automatically set the viewing environment for viewing the user again to the user's preference.

C. Modified Example Next, a modified example of the above-described embodiment will be described with reference to FIGS.
(1) First Modification In the above-described embodiment, when performing the second and subsequent reproductions, the part that has been fast-forwarded (or the part that has been fast-reversed) at the time of the initial reproduction is skipped and the fast-forward destination (or fast-rewind destination) is started. I tried to play it. On the other hand, in the first modified example, when the second and subsequent reproductions are performed, only the fast-forwarded part during the first reproduction is reproduced. The operation of the reproduction process according to the first modification will be described below with reference to FIG.

  When the user operates the remote controller 1 a to perform the second and subsequent playbacks, the control unit 2 generates a playback command and sends it to the hard disk device 6. The hard disk device 6 reads out operation information given to the recorded data RD prior to the reproduction of the recorded data RD and sends it to the control unit 2. The control unit 2 determines whether or not the first playback is based on the viewed flag F in the operation information. If the viewed flag F is “1”, the control unit 2 determines that the reproduction is performed for the second time or later, and executes the reproduction process according to the first modification shown in FIG.

  When the reproduction process is executed, the control unit 2 advances the process to step SE1, and creates a reproduction table RT (see FIG. 4) and a control table CT based on operation information read by the hard disk device 6 prior to reproduction of the recorded data RD. And stored in the RAM 7. Next, in step SE2, the time counter is reset. The time counter is counted by timer interrupt processing (not shown). Then, in steps SE3 to SE4, the event is advanced to the event that has started fast-forwarding at the time of the first reproduction among the events registered in the reproduction table RT. When the event that has started fast-forwarding at the time of the first reproduction is reached, the determination result in step SE4 is “YES”, and the flow proceeds to step SE5. In step SE5, the hard disk device 6 is instructed to reproduce the fast-forwarded part at the first reproduction.

If the event time indicating the execution timing of the volume change or screen setting change registered in the control table CT coincides with the time count value when the fast-forwarded part is being played back during the first playback, the determination result in step SE6 is “YES”. In step SE7, the volume change or screen setting change is performed in accordance with the corresponding volume change event or screen setting change event in the control table CT.
Thereafter, steps SE3 to SE8 are repeated until the event step reaches the end code or until the user performs the playback end operation. When the event step reaches the end code or when the user performs the playback end operation, the determination result of step SE8 Becomes “YES”, and this processing is completed.

(2) Second Modification In the above-described embodiment, when performing the second and subsequent playbacks, the part that has been fast-forwarded (or the part that has been fast-rewinded) during the first playback is skipped and the fast-forward destination (or fast-rewind destination) is started. I tried to play it. On the other hand, in the second modified example, every time the skip key is operated, the playback is started by skipping to the event that has started playback at the first playback (the part that started playback after fast forward, fast reverse, or playback stop). Hereinafter, the operation of the reproduction process according to the second modification will be described with reference to FIG.

  When the user operates the remote controller 1 a to reproduce the recorded data RD, the control unit 2 generates a reproduction command and sends it to the hard disk device 6. The hard disk device 6 reads out operation information given to the recorded data RD prior to the reproduction of the recorded data RD and sends it to the control unit 2. The control unit 2 determines whether or not the first playback is based on the viewed flag F in the operation information. If the viewing completion flag F is “1”, the control unit 2 assumes that the reproduction is performed for the second time or later, and executes the reproduction process shown in FIG. When the reproduction process is executed, the control unit 2 proceeds to step SF1.

  In step SF1, a reproduction table RT (see FIG. 4) and a control table CT are created based on the operation information read by the hard disk device 6 prior to reproduction of the recorded data RD and stored in the RAM 7. Next, in step SF2, the time counter is reset. The time counter is counted by timer interrupt processing (not shown). Subsequently, in step SF3, the hard disk device 6 is instructed to start reproduction of the recorded data RD.

  In steps SF4 to SF6, it is determined whether or not there is a skip key operation, a reproduction stop operation, and a reproduction end operation. When the reproduction stop operation or the reproduction end operation is performed, the determination result of steps SF5 and SF6 is “YES”, and this process is finished. When the skip key operation is performed, the determination result in step SF4 is “YES”, and the process proceeds to step SF7. In step SF7, after instructing the hard disk device 6 to skip to the event (the next reproduction start event) which is after the current time counter value among the events registered in the reproduction table RT and started reproduction at the first reproduction, In step SF3, the hard disk device 6 is instructed to start reproduction.

(3) Other Modifications In the above-described embodiment, the operation information having the viewed flag F indicating whether or not the viewing has been performed is provided in the recorded data RD. Therefore, in another modification, an unviewed recorded program is automatically and continuously reproduced using the viewed flag F in the operation information. That is, the recorded data RD having the operation information whose viewing flag F is “0” is selected from the recorded data RD for each recorded program recorded in the recorded data area RDA (see FIG. 2) of the hard disk device 6. Reproduce. In this way, the recorded data RD which has been recorded and forgotten to be viewed can be automatically and continuously reproduced.
In addition, when recording data RD is overlapped when the recording data area RDA of the hard disk device 6 is small, the watched flag F in the operation information is reset to zero and the recording date and time in the program information is updated. Even though it is an overlap recording, it can be recorded on a medium as recording data RD of a newly recorded program.
