Description

  The present invention relates to a broadcast receiving / recording / reproducing apparatus for recording / reproducing a large-capacity recording medium such as an optical disc, a hard disk, or a semiconductor memory, and to a broadcast receiving / recording / reproducing apparatus for broadcasting for recording / reproducing a broadcast program in a television broadcast or the like. .

  Conventionally, a VTR using a video tape is known as a recording / reproducing apparatus for recording / reproducing contents of video (and audio) such as a TV program, but in recent years, it is referred to as an HDD recorder or a DVD recorder. A recording / reproducing apparatus using a large-capacity recording medium such as a hard disk, an optical disk, or a semiconductor memory is known. In a recording / reproducing apparatus using a randomly accessible recording medium such as a hard disk, a viewer can reproduce other recorded programs while recording a desired program.

  In addition, by using a large-capacity recording medium that enables high-speed random access such as a hard disk, time-shift playback at the same time as recording and playback, such as playback of already recorded programs while recording programs being broadcast, etc. is there. In addition, there is an apparatus that can record a specific program by an apparatus including a plurality of broadcast receiving means and can view other programs being broadcast. Furthermore, a function called cache recording / reproduction has been proposed as a function similar to these functions. This cache function is not primarily intended for long-term storage recording, but by temporarily recording a viewing program being broadcast on a recording medium at a predetermined capacity (predetermined time) as a limit, Playback playback is performed within the range stored in the cache when the user wants to view the scene again from the scene, and is also disclosed in the following documents.

  For example, the recording / reproducing apparatus provided with the cache recording function and the reproducing function disclosed in Patent Document 1 wants to re-view a scene that has been missed or a special re-view in a program that the user is casually watching. The aim is that if there is a scene, the user can view the data by playing back the data recorded in the cache.

In addition, the recording / playback apparatuses disclosed in Patent Document 2, Patent Document 3 and Patent Document 4 are provided with a plurality of tuners for receiving and selecting broadcast signals, so that a specific program can be recorded while other programs can be recorded. It can be played back by another tuner and other channels can be viewed while recording a specific program without affecting the recording.

  However, since the cache recording described in Patent Document 1 records a program being viewed, when the user switches the viewing channel, the recorded data in the cache naturally depends on the channel selection. For this reason, in order to make full use of this cache function, it is desirable for the user to switch the channel too darkly, and it is not possible to fully obtain the benefits of this function for users with intense channel movement have.

  In addition, in the time-shift playback of a program using the recording function described in Patent Document 2, Patent Document 3 and Patent Document 4, “chase playback” in which a program that is currently being broadcast is played back with a delay of several minutes and the program is viewed. Is often used, and in such use, the program is often in progress at that time, and if the viewing channel is switched to that channel, There are cases where important scenes of programs that have been enjoyed by “chase play” or programs recorded by a method called “back program recording” are seen first. In particular, if the results of sports broadcast programs and dramas are known in advance, the enjoyment of viewing will be halved, and there will be a problem that only the programs that have been enjoyed will be disappointing. Therefore, when the program is selected while “back program recording” is being performed, the “back program recording” or “ Even if the channel is switched during “chase playback”, it is considered to prevent the result of the program being recorded or played back or an important scene from being viewed first by the current broadcast.

  However, in order to move a channel when a “playback” or “recorded” program is broadcast in this way, the user needs to be careful not to switch to the channel of the program inadvertently, or the device itself may be mistaken. It had a playback prevention function and the user had to use it explicitly. Naturally, the user can enjoy various programs while moving the channel freely to some extent by using the device.

  However, in the conventional apparatus, a new problem arises because the channel can be moved easily when getting used to the above operation. When you are enjoying several programs by switching the channel to the program that is being broadcast at that time while performing the “chasing playback” and “back program recording” described above, and switching the channel between normal broadcast programs If you watch the program that is currently being broadcast with a time shift, such as “chasing playback” by enjoying the same view, you will continue watching beyond the actual program end time. There is a problem that the next program has begun without knowing, and that the first of the program that I wanted to watch is missed.

  The present invention has been made in view of the above problems, and its purpose is to inadvertently view the broadcast of the program at that time, such as during "chasing playback" or "back program recording", and to record data. Listening to the progress of the actual broadcast program due to the playback of the program, suppressing the loss of the program that the user wanted to watch, and switching between the playback video and the broadcast video in the same way as the channel movement between normal broadcast programs An object of the present invention is to provide a broadcast receiving / recording / reproducing apparatus capable of performing the above.

  In order to solve the above-mentioned problem, the present invention according to claim 1 records channel data of a channel selected based on a channel selection signal supplied from an operating means by at least an input operation of a channel selection request from a user.

When the channel number corresponding to the data is the same, the other broadcast receiving means is controlled not to output the channel selection signal corresponding to this channel number.

  The present invention according to claim 2 is the broadcast receiving / recording / reproducing apparatus according to claim 1, wherein the operation means selects a channel to be supplied to the other broadcast receiving means obtained by an input operation of a channel selection request by a user. When the channel number corresponding to the signal and the channel number corresponding to the channel data recorded in the recording means are the same, the recording / reproduction request signal corresponding to this channel number is output to the recording means. The recording / reproduction stop request signal is output by a user's recording / reproduction stop request input operation, and the reproduction means is a data area already recorded in the recording means during the recording operation based on the recording / reproduction request signal. If a recording / playback stop request signal is supplied while the channel data read out from The reproduction output of the channel data is stopped, and the reproduction start index data indicating the stop position in the channel data is recorded in the recording means in association with the channel data, and is recorded when at least the next recording / reproduction request signal is supplied. The reproduction operation is started from the position where the channel data was previously stopped based on the reproduction start index data.

  According to a third aspect of the present invention, there is provided the broadcast receiving / recording / reproducing apparatus according to the second aspect, wherein the reproducing means records the channel data and the reproduction start index data associated with the data in the recording means. When the recording / reproduction request signal is supplied from the operation means, the reproduction start position of the channel data is set to a position a predetermined time before the position corresponding to the associated reproduction start index data and reproduced. It is characterized by starting.

  According to a fourth aspect of the present invention, there is provided the broadcast receiving / recording / reproducing apparatus according to the second aspect, wherein the commercial detecting means detects the start position and the end position of the commercial data from the channel data extracted from one of the broadcast receiving means. The reproduction means further includes a case where the channel data and the reproduction start index data associated with the data are recorded on the recording means, and when the recording / reproduction request signal is supplied from the operation means, the reproduction means When the start position obtained from the index data is within the period of the detected commercial data start position and end position, reproduction output is started from a position a predetermined time before the start position of the commercial data. Features.

  According to the present invention, when performing “back program recording” or “chase playback” by the operation function, playback and recording function, etc. while switching to another program being broadcast at the same time, Switching between broadcast program images can be operated in the same manner as switching between normal broadcast programs, and viewing can be enjoyed. Furthermore, at the time of “chase playback” started in the same way as channel switching, the user can casually recognize that this video is a playback video, and the current time is displayed on the playback video, so that The program can be prevented from being overlooked due to “inadvertent mistakes” such as overrunning the start of the program, and the channel can be changed easily, and the broadcast video of the program being recorded during the changeover is inadvertent This makes it possible to provide an easy and considerate operating environment that can prevent the user from knowing important scenes and results of the program before enjoying the recorded video.

  Here, with reference to FIG. 4, the remote control part (remote control) used for operation of the broadcast receiving / recording / reproducing apparatus will be briefly described. In this broadcast receiving / recording / reproducing apparatus, it is common for a user to remotely operate the broadcast receiving / recording / reproducing apparatus using a remote controller, and in this description, the operation using the remote controller will be mainly described. Needless to say, it can be controlled by using the operation buttons provided on the front panel of the apparatus main body.

  The remote controller 23 includes a power switch 24, a channel direct designation operation unit 25 that directly designates a channel station number using a numeric button in channel switching, and Up-Down (current channel selection channel) from the current channel. A channel relative instruction operation unit 29 specified by a channel 1 plus or minus 1 channel), a pause instruction operation unit 26 for pausing a playback video of recorded data, and a playback state or a recording state. A stop instruction operation unit 27 for stopping, a reproduction instruction operation unit 28 for instructing reproduction of recorded data, and a recording instruction operation unit 30 for instructing recording start are provided.

  Further, as shown in FIG. 5, it is assumed that this remote controller is operating in an environment where reception of broadcasting stations assigned to each channel is possible, and the channel direct buttons which are numeric buttons of the remote controller 23 shown in FIG. Each channel number shown in FIG. 5 is assigned to each numeric button of the designation operation unit 25. By operating the channel direct designation operation unit 25, it is possible to directly switch to the channel designated by the user regardless of which channel is currently selected, and by operating the channel relative instruction operation unit 29, the "Up" Channels can be sequentially switched by the “Down” operation.

  The channel selection signal is output by the operations of the channel direct designation operation unit 25 and the channel relative instruction operation unit 29. In addition, a recording / reproduction request signal is output by operating the reproduction instruction operation unit 28, and a recording / reproduction stop request signal is output by operating the stop instruction operation unit 27.

  Here, with reference to FIG. 6, the basic channel switching operation by the “Up” and “Down” operations will be described.

  First, as shown in FIG. 6, for example, when the first selected channel is “CH1”, the operation is switched to “CH3” by the Up operation 31, and the operations of the Up operations 32, 33, 34, 35, and 36 are further performed. As a result, the channel is sequentially switched to “CH4”, “CH6”, “CH8”, “CH10”, and “CH12”, and the Up operation of returning to “CH1” by the Up operation 37 is performed. Similarly, for the operations of “Down” operation 44, 43, 42, 41, 40, 39, 38, the channels are sequentially set to “CH10”, “CH8”, “CH6”, “CH4”, “CH3”, “CH1”, and so on. Switched Down cyclic operation.

  Here, a basic example of the temporary recording timing of the broadcast signal (input signal 2 or 3) will be described with reference to FIG.

  In this description, the horizontal axis of these timing image diagrams is time (t), the vertical item is the state of each part (user request: U, tuner status: Tu, temporary recording content: C, playback status of temporary recording: P, display Display state: D, etc.). In the following description, the following notation is used. For example, “U (t7) = Ch1” shown in the upper right of FIG. 3 issues a channel switching request to the Ch1 channel at the timing t7. Similarly, “Tu2 (t3) = Ch4” indicates that tuner 2 has selected Ch4 at timing t3. Hereinafter, the same expression is used in the description of the timing images of FIGS. 9, 10, 12, 15, and 16.

  As shown in the figure, when the user outputs a channel switching request U (t0) = Ch1, the tuner 1 state Tu1 becomes Tu1 (t0) = Ch1, and the display D becomes display D (t0) = Ch1. Next, when the user requests U (t1) = recording to record this channel, the recording of temporary recording C1 (t1) = Ch1 starts. In this recording state, when the user requests a channel switching request U (t2) = Ch3, U (t3) = Ch4, the tuner Tu2 not used for recording is Tu2 (t2) = Ch3, Tu2 (t3) = Ch4 and the user Channel selection is performed in response to the request, and the display is switched to display D (t2) = Ch3 and D (t3) = Ch4 so that the received video can be viewed, and further, the user requests channel switching of U (t4) = Ch1. Is output, the display output signal is switched to the signal from the tuner Tu1, and D (t4) = Ch1. In this basic example, when switching to the same channel as during recording is performed, viewing is performed using Tu1 that has already been selected, but channel selection is performed using Tu2 instead of Tu1. It may be.

  Next, when the user requests U (t5) = reproduction, processing of C1 reproduction state P1 (t5) = reproduction Ch1 is performed, and this reproduced image is displayed on display D as D (t5) = reproduction Ch1. . Next, when the user requests U (t6) = stop Ch1 to watch another channel (Ch4) once, the playback state P1 (t6) = stop of C1 and the channel Tu4 selected by the tuner Tu2 on the display D Is displayed on the display D (t6) = Ch4, and then U (t7) = Ch1, D (t7) = Ch1, and then the reproduction request U (t8) = reproduction is output from the user again. Thus, reproduction from the position stopped at the previous t6 is performed.

  Next, the channel switching operation of the broadcast receiving / recording / reproducing apparatus according to the first embodiment of the present invention will be described with reference to FIG. FIG. 7 shows an image of the channel switching operation when channel switching is performed in order to view other channels during the recording operation of a specific channel (here, CH4).

  As shown in the figure, for example, when another channel (for example, “CH1”) is being watched while channel CH4 is being recorded and the channel relative instruction operation unit 29 is operated with Up operations 31 and 32, it is selected first. When the channel is switched from “CH1” to “CH3” and then originally switched to “CH4”, when the channel is being recorded, the channel is skipped and switched to the next channel “CH6”. Perform switching skip operation. Similarly, if the Down operation 41 is performed while the channel “CH6” is selected, “CH4” being recorded is skipped and the channel “CH3” is selected.

  Next, the channel switching operation of the broadcast receiving / recording / reproducing apparatus according to the second embodiment of the present invention will be described with reference to FIG. FIG. 8 is an image of the channel switching operation by the channel relative instruction operation unit 29 during recording of the channel “CH4” as in FIG.

  As shown in the figure, for example, the channel “CH4” being recorded is in the switching order in which “CH4” is normally selected by the Up operation 32 or the Down operation 41 of the channel relative instruction operation unit 29. In the example, when the channel is being recorded, it is switched to the playback video of the recorded data.

  Further, when the Up operation 33 or the Down operation 40 is performed by the channel relative instruction operation unit 29 while the recorded data is being reproduced, the reproduction operation is stopped, and further channel selection is performed from the channel at the time of broadcasting this data. Do. That is, in FIG. 8, the channel is switched to “CH6” by the Up operation 32 and “CH3” by the Down operation 41. Note that when another channel is selected during recording of a specific channel, the channel can be directly switched using the channel direct designation operation unit 25.

  Next, the operation of each control unit when the channel switching operation of the second embodiment is performed will be described with reference to FIG. This timing operation is an image of the control timing of the channel switching operation shown in FIG. 8 performed when the channel Ch1 is recorded in the temporary recording means C1, and is selected by an operation button for making a channel selection request by the user. The tuner tuning and recorded data playback operation are shown.

  As shown in the figure, first, when the user selects a channel switching request U (t17) = Ch1 using the direct operation unit 25, the tuner Tu1 is switched to Tu1 (t17) = Ch1, and the user is further relative. When channel selection is performed by the Up operation using the instruction operation unit 29, the tuner Tu2 (t17) is switched to Ch3. When the Down operation is performed here, the tuner Tu1 is switched to Tu1 (t19) = Ch1.

  Next, when the playback instruction button is used to instruct the temporary recording C1 to play back the data being recorded, the Up operation switches from the channel of the recording data being played back to the playback position (ST1) of the same channel as the Up operation. Here, since the data being reproduced is Ch1, the tuner 2 is used to select the channel Tu2 (t22) = Ch3. Thereafter, the channel of the tuner Tu2 is further switched to Tu2 (t24) = Ch4 and Tu2 (t25) = Ch6 by the Up operation, and the channel is switched to Ch12 by using the direct instruction operation unit 25, and then the channel Ch1 by the Up operation. Is started, the reproduction of data being recorded is started from the position (ST2) during the previous reproduction.

  Next, the reproduction timing of the temporary recording C1 applicable to the first and second embodiments will be described with reference to FIG. As shown in the figure, when the user switches the channel at the request of U (t32) = Ch1, and the user records another channel when the user temporarily records in the temporary recording means C1 while watching the channel Ch1. For viewing, a request for switching U (t34) = Ch3 and U (t35) = Ch4 is output, and the tuner Tu2 is used to switch the channel to Tu2 (t34) = Ch3 and Tu2 (t35) = Ch4, respectively. After viewing, when the user requests switching of U (t36) = Ch1, the Ch1 data being recorded is reproduced in the temporary recording means C1. At this time, the reproduction is started from the P0 position that is a predetermined time later than C1 (t34) that was last viewed in the Ch1 broadcast. As a result, the video reproduced at D (t36) to D (t37) of the viewing video display D is reproduced as the last video scene viewed at the time of the previous viewing. Furthermore, this playback is stopped by the user request of U (t40) = Ch4, and again by the request of U (t41) = Ch1, the playback is started from the position of P1 that is a certain time backward from the previous playback position. By seeing the scene you see again, you can make the user aware that it is a playback video.

  Here, with reference to FIG. 11, the process procedure of the system control means 1 for performing the said operation | movement is demonstrated. However, here, in order to simplify the description, the description will be limited to channel switching and temporary recording operations.

  First, the broadcast receiving / recording / reproducing apparatus is turned on to activate the apparatus.

  In step S1, the system control unit 11 reads a system activation program recorded in advance in the ROM, and activates the tuners 1 and 2 as part of the activation process.

  In step S2, the system control means 11 confirms the data reception status of the tuners 1 and 2 via the signal selection means 10, and if neither of the tuners has started reception, the priority order is set high in advance. The reception of video data from the tuner 1 is started. Then, the system control unit 11 causes the recording signal processing unit 51 to acquire the same video data through the recording control unit 52 in two systems of storage video data and real-time display video data. Then, the storage video data is instructed to perform recording signal processing such as compression processing, and the real-time display video is instructed to be displayed on a display device described later. Next, the system control unit 11 instructs the recording media management unit 53 to store the video data processed by the recording signal processing unit 51. The recording media management means 53 causes the temporary recording means 54 to record the video data that has undergone the recording signal processing acquired via the recording control means 52.

  In step S3, the system control means 11 records the video data acquired as the real-time display video data in step S2, the recording signal processing means 51, the recording control means 52, the recording media management means 53, the reproduction control means 12, and the display control means. 14 and the display display Y processing means 15 are displayed on a display monitor (TV or the like).

  In step S4, the system control means 11 confirms whether or not the data recorded in the temporary recording means 54 is being reproduced, and if it is being reproduced, proceeds to step S5.

  In step S5, the system control means 11 confirms whether or not there is a reproduction stop request. If there is no reproduction stop request, the system control means 11 returns to step S3 and continues reproduction. If there is a playback stop request, the process proceeds to step S6.

  In step S 6, the reproduction start index assigning unit 112 of the system control unit 11 stops the reproduction, and records the reproduction stop position and the next continuous reproduction position in the recording unit 56.

  In step S7, the system control means 11 confirms whether or not there is a channel change request, and if there is no channel change request, returns to step S3 to display the original channel. If there is a channel change request, the process proceeds to step S13.

  On the other hand, if the data recorded in the temporary recording means 54 in step S4 is not being reproduced, the process proceeds to step S8.

In step S8, the system control means 11 confirms whether there is a channel switching request from the user, waits for a switching request until there is a channel switching request, and if there is no change request, proceeds to step S9, where the change request is If there is, the process proceeds to step S13 in order to determine which tuner can select the requested channel.

  In step S9, the system control means 11 confirms whether or not there is a reproduction request to the temporary recording device 54. If there is no request, the system control means 11 returns to step 8 to confirm a channel change request, and if there is a request, proceeds to step S10. .

  In step S10, the system control means 11 confirms whether or not there is a viewing history of data temporarily recorded before the current time based on the presence or absence of the last viewing point, and indicates a point mark indicating the middle of the last viewing point data. If there is no point mark, the process proceeds to step S11, and if there is a point mark, the process proceeds to step S22.

  In step S11, the system control means 11 starts reproduction from the beginning of the data, and returns to step S3.

  On the other hand, if there is a point mark indicating that the final viewing point is in the middle of the data in step S10, the system control means 11 starts playback from a position that is further back from the final viewing position in step S22. Return to S3.

  On the other hand, if it is determined in step S13 that there is a channel change request in step S7 and step 8, the system controller 11 selects the tuner 1 to determine which tuner can select the requested channel. Check the status. As a result of the confirmation, if the channel being selected is not fixed for recording or the like, the process proceeds to step S19, and if it is fixed, the process proceeds to step S21.

  In step S19, the system control unit 11 selects the requested channel using the tuner 1, and in step S20, processes the output of the tuner 1 for display, and returns to step S3.

  On the other hand, in step S21, the system control means 11 confirms whether or not there is a request for switching to a fixed (recording) channel, and if the channel switching request is a request for this fixed channel. The process proceeds to step S10, and if the channel switching request is not a request for a fixed channel, the process proceeds to step S14.

  In step S14, the channel skip unit 111 of the system control unit 11 checks the status of the tuner 2, and if it is not used for recording or the like, selects the requested channel using the tuner 2 in step S15. In S16, the display output signal is switched to the signal from the tuner 2. In step S17, the viewing point in the tuner 1 is confirmed, and the channel selection channel of the tuner 2 is started to be recorded in the temporary recording means 55, and the process returns to step S3 for display. To do.

  In this case, scheduled recording has priority over temporary recording, so if any tuner is used for scheduled recording, the operation is simplified on the assumption that the channel request is performed when there is no available channel. It is explained. Therefore, when both tuners are performing scheduled recording, there may be a case where channel switching itself is not permitted.

  Next, with reference to FIG. 12, the operation of each control unit when a channel switching operation according to the third embodiment of the present invention is performed will be described.

  As shown in the figure, when the user switches the channel with a request of U (t46) = Ch1, and the user records another video while viewing the video while fixing the channel to Ch1 in the temporary recording means C1. In order to view the channel, a request for switching U (t48) = Ch3 and U (t49) = Ch4 is issued, and the tuner Tu2 is used to switch the channel to Tu2 (t48) = Ch3 and Tu2 (t49) = Ch4, respectively, and broadcast. Then, when the user requests switching of U (t50) = Ch1, the Ch1 data being recorded is reproduced to the temporary recording means C1. At this time, the reproduction start position is reproduced from the P0 position that is a predetermined time later than C1 (t48) at which the Ch1 broadcast was last viewed. As a result, the video reproduced at D (t50) to D (t51) of the viewing video display D is reproduced as the last video scene viewed at the time of the previous viewing. Further, this playback is stopped by a user request of U (t56) = Ch4, and again at the request of U (t57) = Ch1, the previous playback stop position is in the CM. By replaying from the position of P1 that goes back, it is possible to make the user aware of the fact that it is now a replayed video by letting the user see the scene of the last viewed program again.

  With reference to FIG. 13, the processing procedure of the system control means 1 for performing the said operation | movement is demonstrated. However, here, in order to simplify the description, the description will be limited to channel switching and temporary recording operations. Note that this processing step differs from the processing step of FIG. 11 in that steps S23 and S24 are provided after step S10, and that step S17 is provided instead of step S6.

  First, the broadcast receiving / recording / reproducing apparatus is turned on to activate the apparatus.

  In step S1, the system control unit 11 reads a system activation program recorded in advance in the ROM, and activates the tuners 1 and 2 as part of the activation process.

  In step S2, the system control means 11 confirms the data reception status of the tuners 1 and 2 via the signal selection means 10, and if neither of the tuners has started reception, the priority order is set high in advance. The reception of video data from the tuner 1 is started. Then, the system control unit 11 causes the recording signal processing unit 51 to acquire the same video data through the recording control unit 52 in two systems of storage video data and real-time display video data. Then, the storage video data is instructed to perform recording signal processing such as compression processing, and the real-time display video is instructed to be displayed on a display device described later. Next, the system control unit 11 instructs the recording media management unit 53 to store the video data processed by the recording signal processing unit 51. The recording media management means 53 causes the temporary recording means 54 to record the video data that has undergone the recording signal processing acquired via the recording control means 52.

  In step S3, the system control means 11 records the video data acquired as the real-time display video data in step S2, the recording signal processing means 51, the recording control means 52, the recording media management means 53, the reproduction control means 12, and the display control means. 14 and the display display Y processing means 15 are displayed on a display monitor (TV or the like).

  In step S4, the system control means 11 confirms whether or not the temporary recording means 54 is being reproduced, and if it is being reproduced, proceeds to step S5.

  In step S5, the system control means 11 confirms whether or not there is a reproduction stop request. If there is no reproduction stop request, the system control means 11 returns to step S3. If there is a playback stop request, the process proceeds to step S6.

  In step S6, the system control unit 11 stops the reproduction and records the reproduction stop position and the next continuous reproduction position.

  In step S7, the system control means 11 confirms whether or not there is a channel change request, and if there is no channel change request, returns to step S3 to display the original channel. On the other hand, if there is a channel change request, the process proceeds to step S13.

  On the other hand, if the temporary recording means 54 is not reproducing in step S4, the process proceeds to step S8.

In step S8, the system control means 11 confirms the presence or absence of a channel switching request from the user, waits for a switching request until there is a channel switching request, proceeds to step S9 if there is no change request, and if there is a change request, The process proceeds to step S13 in order to determine which tuner can select the requested channel.

  In step S13, the system control means 11 confirms the channel selection state of the tuner 1 and performs channel selection with an empty tuner in the following steps.

  In step S9, the system control means 11 confirms whether or not there is a reproduction request to the temporary recording device 54. If there is no request, the system control means 11 returns to step 8 to confirm a channel change request, and if there is a request, proceeds to step S10. .

  In step S10, the system control means 11 confirms whether or not there is a viewing history of data temporarily recorded before the current time based on the presence or absence of the final viewing point, and a point mark indicating the middle of the final viewing point data is displayed. If there is no point mark, the process proceeds to step S11. If there is a point mark, the process proceeds to step S23.

  In step S23, the commercial determination unit 113 of the system control unit 11 confirms whether or not the position of the final viewing point is in the CM (commercial). If it is in the CM, the process proceeds to step S24.

  In step S24, the system control means 11 detects the head of the CM, performs playback from a position further back from the CM head position for a fixed time, and returns to step S3.

  On the other hand, if the final viewing position is not a CM in step S23, the system control unit 11 starts reproduction from a position that is further back by a predetermined time from the final viewing position in step S22, and returns to step S3.

  In addition, since the process after step S13 is the same process as FIG. 11, description is abbreviate | omitted here.

  As described above, by performing the timing operation and process control of FIGS. 12 and 13, the channel switching and the reproduction of recorded data can be switched flexibly and smoothly according to the operating environment as in the first and second embodiments. Even when watching the program while switching the program, when the program is played back, the viewer can be conscious that it is the playback video of the recorded data by showing the last viewed scene again, so that the next program can be viewed. It can make you conscious.

  In the first to third embodiments, in addition to this embodiment, the effect can be further obtained by devising the display shown in FIG.

  FIGS. 14A to 14D are diagrams showing examples of display displayed on a display connected to the broadcast receiving / recording / reproducing apparatus of the present invention.

  A broadcast receiving / recording / reproducing apparatus 49 equipped with the present invention shown in FIG. 14A is connected to an antenna 48 for receiving a broadcast signal, and is further connected to a display device (TV through a video / audio signal transmission cable 47. 45) is connected. In addition, the display device 45 includes a display unit 46, and reproduces and displays video on the display unit 46.

  The broadcast receiving / recording / reproducing apparatus 49 equipped with the present invention shown in FIG. 14 (b), when reproducing recorded data recorded in advance on the display unit 46 of the display device 45, At a timing such as the CM end time or a specific break time (for example, 00 minutes or 30 minutes), a display 50 indicating that the playback operation is currently being performed is output and displayed on the display unit 46 for a certain period of time.

  The broadcast receiving / recording / reproducing apparatus 49 equipped with the present invention shown in FIG. 14 (c) is slightly more than the area size of the display unit 46 when reproducing recorded data recorded in advance on the display unit 46 of the display unit 45. By outputting and displaying a small-sized video 51, the viewer can visually recognize that the current video is a reproduction of recorded data.

  As shown in FIG. 14 (d), the broadcast receiving / recording / reproducing apparatus 49 in which the present invention is installed reproduces the recording time recorded in advance on the display unit 46 of the display device 45, the end time of the program currently being broadcast, A time display 52 indicating the current time is displayed on the screen for a certain period of time on the display unit 46 at a timing such as a CM end time or a specific break time (for example, 00 minutes, 30 minutes).

  Furthermore, in the broadcast reception recording / reproducing apparatus including the recording means for storage and the temporary recording means as in the present invention, it is possible to perform simple reproduction and channel selection using data recorded by the temporary recording means. It can be easily predicted that there may be a case where the data of the temporary recording device cannot be viewed until the end because of insufficient time. For this reason, normally, the data recorded in the temporary recording means is stored in a storage device for storage and viewed again at a later date. However, in the case where the user enjoys the recorded data while easily going back and forth between the recorded data reproduction and viewing and the broadcast channel viewing in the present invention, how far the recorded data has been viewed and how many programs are in the recorded data. It may become unclear whether recording is performed, and the playback position cannot be determined quickly at a later date.

  Thus, with reference to FIGS. 15 and 16, fourth and fifth embodiments for solving the above problem will be described.

  This broadcast receiving / recording / reproducing apparatus records the last viewing point of the program in the recording data in the fourth embodiment when recording the data of the temporary recording apparatus as the storage data in the recording apparatus, and temporarily records the data in the fifth embodiment. When recording data composed of a plurality of programs recorded in the recorded data, it is possible to quickly select the playback position when enjoying the stored data at a later date by recording information indicating the boundaries of the program together It is.

  Specifically, FIG. 15 shows that the user switches the channel with U (t65) = Ch1 and records this channel on the temporary recording means, and changes the channel Ch1 until the next channel switching U (t67) = Ch4. I watch and then watch Ch4. At this time, in order to enjoy the recording data of this temporary recording C1 at a later date, when recording recording U (t68) = recording is started, the recording data is accompanied by information indicating that it has already been watched by broadcasting from t65 to t67 Record.

  On the other hand, FIG. 16 shows that when the data remaining in the temporary recording C1 is stored, if the data is composed of a plurality of programs, boundary position information for each program is recorded simultaneously. is there.

  According to this, when data composed of a plurality of programs recorded in the temporarily recorded data is recorded, information indicating the boundary of the program is recorded together, so that the stored data can be quickly enjoyed at a later date. The playback position can be selected.
