Abstract

<P>PROBLEM TO BE SOLVED: To enable a user to view some programs broadcasted in the past while preventing recording capacity of data from being wasted. <P>SOLUTION: When a plurality of programs broadcasted continuously in a certain channel is temporarily recorded and a user performs time-shift reproduction of the program temporarily recorded (when the user views the program), data of the program before the previous program timewisely based on the program being viewed by the user is erased from DB124 in a program unit. For example, the data of the program before the previous program timewisely based on the program being viewed is erased when the prescribed time elapses such as one minute after reproduction of the reference program is started. This invention can be applied to equipment having a video recording function. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to an information processing apparatus, an information processing method, and a program, and in particular, allows a user to trace back several programs broadcast before a program being viewed while preventing wasteful use of data recording capacity. The present invention relates to an information processing apparatus, an information processing method, and a program that can be viewed.

  In a recording device such as a hard disk recorder that has been widely used in recent years, a user can determine the position of a program that is delayed from the broadcast position by playing back recorded data while recording the program being broadcast. Many of them are equipped with a so-called chasing playback function that enables viewing.

  By the way, in the case of chasing playback, there is a problem with the handling of recorded program data. For example, if the chasing playback function erases the program data of the part that the user has finished watching, the user will follow the chasing playback. I can't see a scene I missed during playback.

  On the other hand, even if the user finishes watching the chasing playback function, if the program data is continuously stored without being deleted, the storage capacity of the hard disk may be wasted as a result.

  The present invention has been made in view of such a situation, and allows a user to retroactively view several programs broadcast before the program being viewed while preventing wasteful use of data recording capacity. Is to be able to.

  An information processing apparatus according to one aspect of the present invention is capable of recording a plurality of programs broadcast continuously in an information processing apparatus capable of recording a program and reproducing a recorded program part in parallel. When a predetermined program of the plurality of recorded programs is played back, a program that is broadcast and recorded a predetermined number of times before the predetermined program as a reference Management means for erasing the entire data is provided.

  The management means further records the data of the entire predetermined program according to an instruction from the user, excluding the predetermined program from an object to be erased when another program is being played back. It can be managed as the data of a completed program.

  The management means can delete the data of the entire program that has been broadcast and recorded two times before the predetermined program as a reference.

  The management means, when a predetermined time has elapsed since the reproduction of the predetermined program has started, a program that has been broadcast and recorded a predetermined number of times before the predetermined program as a reference The entire data can be erased.

  An information processing method or program according to one aspect of the present invention provides an information processing method for an information processing apparatus capable of performing recording of a program and playback of a recorded program portion in parallel, or the information processing on a computer. In the program to be executed, when a plurality of programs broadcast continuously are recorded and a predetermined program among the plurality of recorded programs is reproduced, the predetermined program is used as a reference. And erasing data of the entire program that has been broadcast in time and recorded.

  In one aspect of the present invention, when a plurality of programs to be continuously broadcast are recorded and a predetermined program among the plurality of recorded programs is reproduced, the predetermined program is As a reference, the data of the entire program broadcast and recorded a predetermined number of times ago is deleted.

  According to an aspect of the present invention, it is possible to prevent wasteful use of data recording capacity. At the same time, the user can go back and watch several programs broadcast before the program being viewed.

  When the position of the program display unit 31 is moved, as shown in FIG. 4, the display range of the list display unit 32 is expanded to the portion where the program display unit 31 was displayed in the fixed mode. .

  FIG. 5 is a block diagram illustrating a hardware configuration example of the personal computer 1 that performs the screen display as described above.

  A CPU (Central Processing Unit) 101 executes various processes according to a program stored in a ROM (Read Only Memory) 102 or a storage unit 109. A RAM (Random Access Memory) 103 appropriately stores programs executed by the CPU 101 and data. These CPU 101, ROM 102, and RAM 103 are connected to each other by a bus 104.

  An input / output interface 105 is also connected to the CPU 101 via the bus 104. A one-segment tuner 106 is connected to the input / output interface 105.

  The one-seg tuner 106 acquires program data (video and audio data) and EPG data broadcast on the channel selected by the user from the one-seg broadcast wave received by the antenna 22, and acquires the acquired program data and The EPG data is output to the display 21 constituting the output unit 108 via the input / output interface 105. In the output unit 108, based on the data supplied from the one-segment tuner 106, a program video, a list of channels, and the like are displayed in the manner described above.

  The personal computer 1 also has a function of recording a program. When recording a program, the one-segment tuner 106 outputs the acquired program data to the storage unit 109 via the input / output interface 105 and stores it. Let

  Connected to the input / output interface 105 are an input unit 107 such as a keyboard and a mouse, an output unit 108 such as a display 21 and a speaker. The CPU 101 executes various processes in response to user operations input from the input unit 107.

  The storage unit 109 connected to the input / output interface 105 includes, for example, a hard disk, and stores various data such as a program executed by the CPU 101 and program data supplied from the one-segment tuner 106. The communication unit 110 communicates with an external device via a network such as the Internet or a local area network.

  The drive 111 connected to the input / output interface 105 drives a removable medium 112 such as a magnetic disk, an optical disk, a magneto-optical disk, or a semiconductor memory, and drives the program or data recorded therein. Get etc. The acquired program and data are transferred to and stored in the storage unit 109 as necessary.

  FIG. 6 is a block diagram illustrating a functional configuration example of the personal computer 1. 6 is realized by the mobile TV application being executed by the CPU 101 in FIG.

  As shown in FIG. 6, in the personal computer 1, a reception control unit 121, a display control unit 122, a recording control unit 123, a DB (Data Base) 124, and a data management unit 125 are realized.

  The reception control unit 121 controls the one-segment tuner 106 to acquire program data and EPG data broadcast on the channel selected by the user from the one-segment broadcast wave. The reception control unit 121 outputs the acquired program data and EPG data to the display control unit 122 when displaying the screen as shown in FIG. 2 on which the video of the program being broadcast and the list of channels are displayed.

  In the one-segment broadcasting, at least program information of a program currently being broadcast on a channel selected by the user and program information of a program to be broadcast next are provided. With respect to the program information of the next and subsequent programs based on the currently broadcast program, the broadcast station can arbitrarily provide program information of up to 10 programs including the currently broadcast program. ing. The program information includes a program title, a program broadcast start time, a program broadcast time, and the like.

  In addition, when recording a program, the reception control unit 121 outputs the acquired program data and EPG data to the recording control unit 123. The reception control unit 121 also acquires EPG data at a predetermined cycle, and outputs the acquired EPG data to the recording control unit 123. The EPG data output to the recording control unit 123 is stored in the DB 124 and used as appropriate for displaying program information.

  The display control unit 122 reproduces the program data supplied from the reception control unit 121, displays the video of the program on the display 21, and outputs sound from the speaker. In addition, the display control unit 122 displays the video of the program and displays a list of receivable channels on the display 21 based on the EPG data. Thereby, a screen as shown in FIG. 2 is displayed.

  When the display control unit 122 is supplied with program data (data of a program that has been temporarily recorded, data of a program that has been definitively recorded) from the data management unit 125, And the video of the program is displayed on the display 21. The video of the program based on the data supplied from the data management unit 125 is also displayed on the video display unit 41 of the program display unit 31. For example, even when a recorded program is being played back, the channel list is displayed on the list display unit 32 when the TV tab 61 is selected, so that the user can watch the recorded program. By selecting a predetermined channel from the list, it is possible to switch the display of the video display unit 41 to a video of a currently broadcast program that has not been recorded.

  The recording control unit 123 stores the program data supplied from the reception control unit 121 in the DB 124 by adding information such as a title, broadcast start time, and broadcast time described in the EPG data.

  The personal computer 1 is provided with a “backward viewing function” and a “TV pause function” as functions that use program recording, and recording by the recording control unit 123 (to the DB 124) according to the setting of these functions and the like. (Program data storage) is different in timing.

  “Back-to-back viewing function” is a function that allows the user to always go back to the scene before the scene being viewed and perform the follow-up playback while viewing the program being broadcast. The user can set the function to be enabled / disabled. For example, when a certain channel is selected and the program being broadcast at that time is being viewed, the setting of the “backward viewing function” is changed from disabled to enabled. Then, the recording (temporary recording) of the program broadcast on the channel is started after the timing when it is changed to valid. While the mobile TV application is running, the recording of the program started here is continued until the “retroactive viewing function” setting is disabled.

  When program B is broadcast following program A, both programs A and B are recorded when the setting of “backward viewing function” is valid, but this means that broadcast of program A ends. At this timing, the recording by the recording control unit 123 is once ended and immediately after the recording of the program B is started. The recording control unit 123 stores the data of each program in different files and stores them in the DB 124. This makes it possible to manage program data in units of programs.

  The scene that can be viewed retroactively is, for example, the scene of the previous program on the basis of the program being viewed by chasing playback. When a plurality of programs continuously broadcast on a certain channel are recorded and the user is watching the program by chasing playback, the data of the two previous programs in terms of time is based on the program being viewed. The program is automatically deleted from the DB 124 without user operation. That is, the recording by the “retro-watching function” is a temporary recording.

  In this way, data of the previous program in time is automatically deleted based on the program being viewed, which may not be viewed retroactively while viewing a program. Thus, it is possible to prevent wasteful use of the storage capacity of the DB 124 (storage unit 109). When watching a certain program, the program that one wants to watch retroactively is often up to the previous program of the program currently being viewed.

  Of course, the data of the previous three programs may be deleted based on the program being viewed, or the data of the fourth previous program may be deleted. The user may be allowed to select the number of previous program data to be automatically deleted.

  As will be described later, by selecting a predetermined program from among the programs that have been temporarily recorded, the user can also determine the recording in units of programs (hereinafter referred to as temporary recording as appropriate). This is called deterministic recording). The program selected by the user as a definitive recording target is excluded from the data to be automatically deleted and registered as a recorded program.

  In addition, since the follow-up reproduction is performed, the recording of the program being broadcast at that time is continued in parallel even during the reproduction of the program that has been temporarily recorded. The personal computer 1 is an apparatus capable of recording a program and reproducing a recorded part in parallel.

  The “TV pause function” is a function that can be used when the “Backward watching function” setting is invalid, and pauses the viewing of a program while watching a program being broadcast (pause) Button 43), and then canceling the pause, it is possible to perform the chasing playback from the position of the paused program. When the pause is performed, the video displayed on the video display unit 41 is displayed as a still image of the video that was displayed at the timing when the pause was performed.

  For example, when the setting of the “backward viewing function” is invalidated and the program is paused while viewing a program being broadcast on a certain channel, the recording of the program after the timing of the pause is started.

  Recording by the “TV pause function” is also temporary recording. When a user is watching a program by releasing the pause and chasing playback, the time two previous in time with respect to the program being watched is used. Program data is deleted from the DB 124 in units of programs. The user can definitely record the program that has been temporarily recorded by the “TV pause function” in the same manner as when the temporary recording was performed by the “backward viewing function”.

  By enabling the retroactive viewing function, all programs broadcast on the same channel are temporarily recorded, so the user can follow-up playback within the range of the temporarily recorded program. Can be done at any time.

  In addition, during chasing playback, it is possible to go back and play back the scene of the program immediately before the program being viewed at that time, so that a missed scene or a scene that the user wants to see can be viewed repeatedly.

  In addition, by using the “TV pause function”, the user can pause a program that is being broadcast, and can follow up the program from the position where the pause was performed.

  Returning to the description of FIG. 6, the DB 124 stores program data and EPG data supplied from the recording control unit 123. For example, when recording is temporarily performed, program data is supplied from the recording control unit 123. Data stored in the DB 124 is managed by the data management unit 125.

  When the chasing playback is instructed by the user, the data management unit 125 sequentially reads out the data of the temporarily recorded program from the DB 124 and sequentially outputs the read program data to the display control unit 122 to display the video of the program. Is displayed.

  In addition, the data management unit 125 performs a temporary recording of a plurality of programs continuously broadcast on a certain channel, and when the user is performing a follow-up playback of the program on which the temporary recording has been performed, The data of the program two previous in time with respect to the program being viewed is deleted from the DB 124 in units of programs. For example, the timing of erasing the data of the previous two programs with respect to the program being viewed is the timing when a predetermined time has passed, such as one minute after the reproduction of the reference program is started It becomes.

  In this way, immediately after the viewing of a program that has been temporarily recorded is started, the data of the program immediately before that program is not erased, but only for a predetermined time after the viewing is started. Since deletion is performed after the elapse of time, even if the user mistakenly performs chasing playback of a different program, it is possible to prevent the data of the unintended program from being deleted.

  Further, the data management unit 125 removes the program data stored in the DB 124 by temporary recording from the target to be automatically deleted when definite recording is instructed by the user. Manage as data.

  The automatic data erasure by the data management unit 125 is not limited to the timing at which a predetermined time has elapsed since the viewing of a certain program by chasing playback as described above, but also the program on which temporary recording was performed. This is also performed at the timing when the playback target is returned to the position currently being broadcast while the user is watching by chasing playback or when the channel is switched.

  For example, in both cases where the playback target is returned to the current broadcast position and when the channel is switched, if the “backward viewing function” setting is invalid, the recording is temporarily recorded until then. All program data is deleted.

  On the other hand, when the “backward viewing function” setting is enabled, when the playback target is returned to the current broadcasting position, recording is temporarily performed except for the data of the program being broadcast and the previous program. The data of the program that has been recorded is erased (temporary recording of the program currently being broadcast is continued), and when the channel is switched, all the data of the program that has been temporarily recorded is erased.

  When the playback target is returned to the currently broadcasting position, the video display unit 41 displays the video of the program being broadcast. When the channel is switched, the video display unit 41 displays the video of the program being broadcast on the switching destination channel.

  Here, details of the display of the reproduction information display unit 42 will be described.

  FIG. 7 is an enlarged view showing the reproduction information display unit 42 in the program display unit 31.

  In the example of FIG. 7, “TV” is displayed on the upper left of the reproduction information display unit 42, and the program whose video is displayed on the video display unit 41 is selected from the list of recorded programs and playback is instructed. It is shown that the program is not being broadcast, but is being broadcast or is being followed. During playback of a program selected from the list of recorded programs, “video” is displayed instead of “television”.

  “Continuous TV novel” is displayed on the right side of “TV”. This represents the title of the program being played. The title is obtained from EPG data.

  A seek bar 131 of a predetermined length is displayed under the title of the program being played, and “12:45”, which is the broadcast start time of the program being played, is shown on the left, and on the right In addition, “13:00”, which is the broadcast end time of the program being reproduced, is displayed. Therefore, the time from “12:45” to “13:00” represented by the entire seek bar 131 in FIG. 7 represents the broadcast time of one program being reproduced.

  The broadcast start time “12:45” is acquired from the EPG data, and the broadcast end time “13:00” is, for example, the broadcast start time “12:45” It is derived from the broadcast time described in EPG data.

  A pointer 132 shown on the seek bar 131 represents the current reproduction position. In the example of FIG. 7, since the seek bar 131 as a whole represents the playback time of one program (“continuous television novel”), the current playback position is a position near the middle of the program.

  As described above, the reproduction information display unit 42 displays the seek bar 131 having a predetermined length, and the time represented by the entire seek bar 131 is switched depending on the range of programs that the user can view.

  Here, a case where program A, program B, and program C are continuously broadcast on the same channel selected by the user will be described. Program A is a program of the title “Continuous TV Novel” broadcasted from 12:45 to 13:00, and Program B is broadcasted from 13:00 to 13:05. It is assumed that the program is titled “News”. Further, it is assumed that the program C is a program with a program name “Studio Park” broadcasted between 13:05 and 14:00.

  First, the display of the reproduction information display unit 42 when the setting of the “backward viewing function” is invalid will be described.

  When the setting of the “backward viewing function” is invalid, the “TV pause function” is activated when an instruction to pause the program being broadcast is issued, and the temporary recording of the program is started. By releasing the pause, the user can cause the follow-up playback from the position of the program that has been paused.

  FIG. 8 is a table of the reproduction information display unit 42 when a predetermined time has elapsed after the pause is performed in the state of FIG. 7 (when the position near the middle of the program A is being reproduced). It is a figure which shows an example. The description of the same part as in FIG.

In FIG. 8, the position represented by time t ₁ is the position of program A corresponding to the time when the user paused. When the pause is performed, the temporary recording is started by the “TV pause function”, and the temporary recording is temporarily displayed as a display indicating the range where the temporary recording is performed, that is, the range that can be viewed by the chasing playback. The range of the seek bar 131 corresponding to the range (broadcast time) of the recorded program A is displayed in a predetermined color such as blue as shown by hatching in FIG.

In the example of FIG. 8, the range from the position represented by time t ₁ to the position represented by time t ₂ is displayed in blue in the entire seek bar 131, and this range can be viewed by chasing playback. It has become.

Position a temporary recording is represented by the time t ₂ is a right end of the range has been performed, chase the position of the limit viewable by reproducing, representing the position of the program A currently being broadcast. As time elapses and the broadcast progresses, the position of the right end of the range displayed in blue moves to the right. Since the position at time t ₁ , which is the time at which the pause is performed, is fixed, the range of the seek bar 131 displayed in blue, which is a viewable range by chasing playback, widens with time.

In FIG. 8, the pointer 132 indicates that the current playback position is the position of the program A that has passed a predetermined time from the position represented by the time t ₁ at which the pause was performed. The position of the pointer 132 also moves to the right as time passes and chasing playback proceeds.

  If the user is within the range of the seek bar 131 displayed in blue, the user moves the pointer 132 on the seek bar 131 by operating the mouse or the like and moves the pointer 132 on the seek bar 131 to thereby change the position of the chasing playback. The position can be switched to.

  FIG. 9 shows a table of the reproduction information display unit 42 when a predetermined time has elapsed since the start of the broadcast of the program B after the broadcast of the program B is started after the program A in a state in which the follow-up reproduction is performed. It is a figure which shows an example.

  When time advances from the state of FIG. 8, the display of the seek bar 131 is as shown in FIG.

  When the broadcast of the program B is started, the temporary recording of the program B is started after the program A. Therefore, in order to show the entire viewable range by the chasing playback, the program B is started from the broadcast start time of the program A. The display of the seek bar 131 is switched from the display of FIG. 8, which represents the broadcast time of the program A as a whole, so that the time until the broadcast end time is represented by the entire seek bar 131.

  That is, since the broadcast start time of program A is “12:45”, “12:45” continues to be displayed on the left of the seek bar 131 as shown in FIG. On the other hand, since the broadcast end time of program B is “13:05”, as shown in FIG. 9, instead of “13:00” displayed so far, “ 13:05 "is newly displayed.

In FIG. 9, the position represented by time t ₃ is a position corresponding to “13:00” which is the broadcast start time of program B as well as the broadcast end time of program A. Accordingly, the scope to a position represented by the time t ₃ from the left end of the seek bar 131 represents the broadcast time of the program A, the range from the position represented by the time t ₃ to the right end of the scrubber 131 the broadcast time of the program B To express. Cut is displayed on the position of the seek bar 131 represented at time t ₃ is the position of the switching of the program.

The blue display indicating the range that can be viewed by the chasing playback is also displayed on the seek bar 131 based on the broadcast time of the program A until then, based on the broadcast time of the program A and the program B. . In FIG. 9, the range from the position represented by time t ₁ to the position represented by time t ₄ is displayed in blue.

In FIG. 9, the position represented by time t ₁ is the position of program A corresponding to the time when the user paused. The position represented by time t ₄ is the limit position of the range that can be viewed by chasing playback, and represents the position of program B currently being broadcast.

  The pointer 132 indicates that the program B is a target for chasing playback. Since the program to be chased and reproduced is program B, “news” is displayed on the upper left in the reproduction information display section 42 as the title of the program being broadcast.

  FIG. 10 shows a display of reproduction information when a predetermined time elapses after the broadcast of the program C is started after the program A and the program B are started, and the broadcast of the program C is started. FIG. 6 is a diagram illustrating a display example of a unit 42.

  When time advances from the state of FIG. 9, the display of the seek bar 131 is as shown in FIG. 10 (the position of the chasing playback is different from the position of FIG. 9).

  When the broadcast of the program C is started, the recording of the program C is started temporarily after the program A and the program B. Therefore, the broadcast start time of the program A is shown in order to show the entire viewable range by the chasing playback. The display of the seek bar 131 is switched from the display of FIG. 9 representing the broadcast times of the program A and the program B as a whole so that the time from the broadcast end time of the program C to the broadcast end time is represented by the entire seek bar 131.

  That is, since the broadcast start time of the program A is “12:45”, “12:45” is continuously displayed on the left of the seek bar 131 as shown in FIG. On the other hand, since the broadcast end time of the program C is “14:00”, as shown in FIG. 10, “13:05” that has been displayed so far is displayed on the right side of the seek bar 131. 14:00 "is newly displayed.

In FIG. 10, the position represented by time t ₃ is a position corresponding to “13:00”, which is the broadcast start time of program A and the broadcast start time of program B. The position represented by time t ₅ is a position corresponding to “13:05”, which is the broadcast start time of program C and the broadcast start time of program C.

Thus, represents the broadcast time ranges program A to the position represented by the time t ₃ from the left end of the seek bar 131, time t ₃ range up positions represented by the time t ₅ from the position the program represented by B Represents the broadcast time of. Further, the range from the position represented by time t ₅ to the right end of the seek bar 131 represents the broadcast time of program C.

The blue display indicating the range that can be viewed by the chasing playback is also displayed on the seek bar 131 based on the broadcast times of the programs A and B until then, based on the broadcast times of the programs A to C. Is done. In FIG. 10, the range from the position represented by time t ₁ to the position represented by time t ₆ is displayed in blue.

In FIG. 10, the position represented by time t ₁ is the position of program A corresponding to the time when the user paused. The position represented by time t ₆ is the limit position of the range that can be viewed by the chasing playback, and represents the position of the program C that is currently being broadcast.

  The pointer 132 indicates that the program A is a target for chasing playback. As described above, the predetermined ranges of the program A, the program B, and the program C are displayed in blue on the seek bar 131 as ranges that can be viewed by the chasing playback, and when the program A is currently viewed, the user The playback position can be traced back from the playback position of the current program A by the rewind operation, and the playback position can be switched from the playback position of the current program A to a position later than that by the fast forward operation.

  In addition, as shown in FIG. 11, when the program B is currently being viewed by chasing playback (the currently broadcast program is the program C), the user sets the playback position to the current program B by rewinding operation. The playback position can be traced back from the position, and the playback position can be switched from the playback position of the current program B to a later position by a fast forward operation.

  Note that, when a program is being chased and reproduced, the data of the program two previous in time is automatically deleted with reference to the program being reproduced, but in FIG. As a reference, the program A data is not yet erased.

  The display of the seek bar 131 shown in FIG. 11 is the same as the display of the seek bar 131 of FIG. 10 except that the position of the pointer 132 is different. The seek bar 131 as a whole represents the time from the broadcast start time of program A to the broadcast end time of program C.

  FIG. 12 is a diagram illustrating an example of display switching of the reproduction information display unit 42 when program data is automatically deleted.

  The display of the seek bar 131 shown in the upper part of FIG. 12 is the same as the display of the seek bar 131 of FIGS. 10 and 11 except that the position of the pointer 132 is different. The seek bar 131 as a whole represents the time from the broadcast start time of program A to the broadcast end time of program C.

  In the display of the seek bar 131 in FIG. 12, the pointer 132 is at a predetermined position of the program C, and the program C is being reproduced. On the seek bar 131, the title of the program C, “Studio Park”, is displayed as the title of the program being reproduced.

  Since the data of the two previous programs in time is automatically deleted based on the program being played back, when the program C is a target to be played back as shown by the seek bar 131 in FIG. Program A is the program whose data is to be erased.

For example, when a predetermined time such as one minute has elapsed after the chasing playback of the program C is started, it is represented at the time t ₃ from the position represented by the time t ₁ stored in the DB 124 by temporary recording. The data of program A up to the position to be deleted is deleted.

  At this time, since the program including the range that can be viewed by the chasing playback (the program in which the data obtained by the temporary recording is stored) is only the program B and the program C, the point of the white arrow in FIG. As shown, the display of the seek bar 131 is switched so that the time from the broadcast start time of the program B to the broadcast end time of the program C is represented as a whole.

  That is, since the broadcast start time of program B is “13:00”, as shown in the lower part of FIG. 12, on the left side of the seek bar 131, it is replaced with “12:45” that has been displayed so far. "13:00" is newly displayed. On the other hand, since the broadcast end time of the program C is “14:00”, “14:00” is continuously displayed on the right of the seek bar 131 as shown in the lower part of FIG.

In the lower part of FIG. 12, the position represented by time t ₃ is a position corresponding to “13:00” which is the broadcast start time of program A and the broadcast start time of program B. The position represented by time t ₅ is a position corresponding to “13:05”, which is the broadcast start time of program C and the broadcast start time of program C.

Therefore, the range from the left end of the seek bar 131 to the position represented by time t ₅ represents the broadcast time of program B. Further, the range from the position represented by time t ₅ to the right end of the seek bar 131 represents the broadcast time of program C.

The blue display indicating the range that can be viewed by chasing playback is also displayed on the seek bar 131 based on the broadcast times of programs A to C until then, based on the broadcast times of programs B and C. Is done. In the bottom of FIG. 12, the range from the left edge of the seek bar 131 represented at time t ₃ to the position of the program C, represented by the time t ₇ is displayed in blue.

  As a result, although the program A cannot be viewed, the user can view the program B retroactively even when the program C is viewed.

  FIG. 13 is a diagram illustrating an example of display switching of the reproduction information display unit 42 when the user instructs to perform definitive recording.

  For example, by pressing the recording button 47 during chasing playback, the user can perform deterministic recording of the program being chased at that time on a program basis. A program selected as a program for definite recording is excluded from a target from which data is automatically deleted and managed as a recorded program.

The display of the seek bar 131 shown at the top of FIG. 13 is the same as the display of the seek bar 131 of FIG. The broadcast time of program A is represented by the seek bar 131 as a whole. Further, the pause by the user is performed at the position represented by the time t _1, range up position (current broadcast position) from the position represented by the time t ₁ is represented by the time t ₂ is displayed in blue ing. Data of program A in the range from the position represented by time t ₁ to the position represented by time t ₂ is stored in DB 124 by temporary recording.

  In the upper example of FIG. 13, the pointer 132 indicates that the position within the range of the program A where the temporary recording has been performed is the target of the chase reproduction.

  For example, when the user instructs definitive recording of the program A by pressing the recording button 47 in such a state, the data of the program A stored in the DB 124 is automatically deleted by temporary recording. As shown at the tip of the white arrow in FIG. 13, the range of the seek bar 131 that has been displayed in blue until then is a range where definite recording has been performed, such as red. Are displayed in a predetermined color. In the lower part of FIG. 13, the type of diagonal lines attached to the seek bar 131 is different from the type of diagonal lines attached to the upper seek bar 131 in FIG. 13 in that the ranges are displayed in different colors. To express.

Since the broadcast of program A is still continued in the lower state of FIG. 13, the position of the right end of the range displayed in red moves to the right as time passes. Since the position at the time t _{1 at which} the pause is performed is fixed, the red range indicating the range in which the definite program has been recorded becomes wider as time passes.

  FIG. 14 is a diagram illustrating another example of switching of the display of the reproduction information display unit 42 when the user instructs to perform definitive recording.

The display of the seek bar 131 shown in the upper part of FIG. 14 is the same as the display of the seek bar 131 in the lower part of FIG. 12 except that the position of the pointer 132 is different. The broadcast time of programs B and C is represented by the seek bar 131 as a whole. Temporary recording from the previous time t ₃ when the broadcasting of the program B is started has been started, and overall, the range to the position of the program C which is represented by the time t ₇ of the program B is displayed in blue Yes. The entire program B and the data of the program C in the range from the position represented by the time t ₅ to the position represented by the time t ₇ are stored in the DB 124 by temporary recording.

  In the upper example of FIG. 14, the pointer 132 indicates that the position within the range of the program B where the temporary recording has been performed is the target of the chase reproduction.

For example, when the user instructs the definitive recording of the program B by pressing the recording button 47 in such a state, the entire program B data stored in the DB 124 by the temporary recording is automatically deleted. As shown at the tip of the white arrow in FIG. 14, the range of the seek bar 131 that has been displayed in blue so far is represented by a time t ₃ that represents the broadcast time of the program B. Only the range from the current position to the position represented by time t ₅ is displayed in red.

  Unlike the case of FIG. 13 in which the target for definitive recording is the program currently being broadcast, the target for definitive recording is the program that has already been broadcast, and its data is recorded temporarily. Are all the programs stored in the DB 124, the entire range representing the broadcast time of the designated program is displayed in red. Thereby, the user can confirm that the program B is registered as a recorded program on a program basis.

  Next, display of the reproduction information display unit 42 when the setting of the “backward viewing function” is valid will be described.

  When the “Back-to-back viewing function” setting is enabled, whenever a mobile TV application is started and a predetermined channel is received, a program recorded on the receiving channel is temporarily recorded. The display of the playback information display unit 42 after the setting of the “backward watching function” is enabled is after the time when the “TV pause function” is working with the setting of the “backward watching function” disabled. Display, that is, the same display as the above-described display when the pause is instructed.

  FIG. 15 is a diagram illustrating a display example of the reproduction information display unit 42 when the setting of the “backward viewing function” is valid.

In FIG. 15, the seek bar 131 as a whole represents the time from the broadcast start time of program A to the broadcast end time of program B. Further, the position represented by time t ₈ represents the position of program A corresponding to the time when the user has enabled the “backward viewing function” setting. Since the temporary recording is started when the setting of the “backward viewing function” is enabled, the range of the seek bar 131 where the temporary recording has been performed is displayed in blue.

  When the “Backward viewing function” setting is enabled and chasing playback is being performed, the user can watch the scenes of the previous program in time based on the program that the user is currently viewing. The data of the program that the user is currently viewing and the data of the previous program are continuously stored. This state is maintained even when the playback position returns to the position currently being broadcast.

  In the example of FIG. 15, the pointer 132 indicates that the playback position has returned to the position currently being broadcast, but in this case, unlike the case where the “backward viewing function” setting is invalid. Even if it exists, the data of the program A and the data of the program B which have been temporarily recorded until then are continuously stored.

  Next, the operation of the personal computer 1 that realizes the display of reproduction information as described above and manages program data will be described with reference to flowcharts.

  First, the processing of the personal computer 1 that controls the display of the seek bar 131 will be described with reference to the flowchart of FIG.

  This processing is performed, for example, when a predetermined channel is selected from the channels displayed in the list display unit 32, or when another channel is selected (switched) while the predetermined channel is selected. ) Start when. When a predetermined channel is selected by the user, program data being broadcast on the selected channel and EPG data of the program are output from the reception control unit 121 to the display control unit 122.

  In step S1, the display control unit 122 displays a seek bar 131 that generally represents the broadcast time of a program that is currently being broadcast on the channel selected by the user, and a pointer 132 on the seek bar 131 corresponding to the current broadcast position. Is displayed. On the left of the seek bar 131, the broadcast start time of the currently broadcast program acquired from the EPG data is displayed, and on the right, the broadcast end time of the currently broadcast program is displayed.

  In step S2, the display control unit 122 determines whether or not the temporary recording of the program being broadcast has started, and waits until it is determined that the temporary recording has started. Temporary recording is performed by the recording control unit 123.

  Since the setting of the “backward viewing function” is enabled or the pause operation is performed while the setting of the “backward viewing function” is disabled, the display control unit 122 performs the program being broadcast in step S2. If it is determined that the temporary recording is started, the process proceeds to step S3, and the range of the seek bar 131 corresponding to the range of the temporarily recorded program is displayed in blue, so that the user can watch by chasing playback. Represents the range that can be done.

  In step S4, the display control unit 122 determines whether or not temporary recording has been performed over a plurality of programs.

  In step S4, the display control unit 122 determines that temporary recording has been performed over a plurality of programs because broadcasting of other programs has started following the program that was being broadcast in the process of step S1. In this case, the process proceeds to step S5, and the display of the seek bar 131 is switched so that the broadcast time of other programs broadcast continuously is also represented as a whole.

  For example, when the program B is started to be broadcast after the program A is temporarily recorded, and the program B is temporarily recorded, the display control unit 122 displays the program A. The display of the seek bar 131 is switched so that the time from the broadcast start time to the broadcast end time of the program B is represented as a whole. The broadcast start time of the program A is continuously displayed on the left of the seek bar 131, and the broadcast end time of the program B is newly displayed on the right. Thereafter, the process is terminated.

  On the other hand, in step S4, the display control unit 122 determines that temporary recording is not performed over a plurality of programs because the program that was being broadcast in the process of step S1 is still being broadcast. In this case, the process of step S5 is skipped and the process is terminated.

  With the above processing, the time represented by the entire seek bar 131 is appropriately switched. As the time represented by the seek bar 131 as a whole is switched, the range displayed in blue indicating the range of the temporarily recorded program is also switched, so that the user has a relationship with the broadcast time of the program. Thus, it is possible to intuitively grasp the range where the temporary recording is performed.

  Note that the processing in FIG. 16 after step S3 is repeated while the temporary recording is continued.

  Next, with reference to the flowchart of FIG. 17, the process of the personal computer 1 that controls the display of the seek bar 131 after the follow-up reproduction is started will be described.

  In this process, for example, three programs broadcast continuously on the same channel are temporarily recorded, and the broadcast time of the three programs (from the broadcast start time of the first program among the three programs in time). The time until the broadcast end time of the last program in time) is represented by the seek bar 131 as a whole, and is started when the last program is being chased and reproduced in time. When the follow-up reproduction is performed, the data of the program two previous in time with respect to the program being reproduced is automatically deleted at a predetermined timing. Also, the user can perform definite recording of the program being played.

  In step S <b> 11, the display control unit 122 determines whether or not the data of the previous two programs has been automatically deleted based on the program being viewed by the user by the chasing playback. The data management unit 125 automatically deletes data stored in the DB 124 by temporary recording.

  If the display control unit 122 determines in step S11 that the program data has been deleted, the display control unit 122 proceeds to step S12 and switches the time represented by the entire seek bar 131.

  For example, when the programs A to C broadcast continuously are temporarily recorded and one minute has passed after the follow-up playback of the program C, the data of the program A is automatically deleted. The display control unit 122 switches the display of the seek bar 131 so as to indicate the time from the broadcast start time of the program B to the broadcast end time of the program C including the range in which the chase reproduction is possible. The broadcast start time of the program B is newly displayed on the left of the seek bar 131, and the broadcast end time of the program C is continuously displayed on the right.

  If the display control unit 122 determines in step S11 that the program data has not been deleted, the display control unit 122 skips step S12 and proceeds to step S13.

  In step S13, the display control unit 122 determines whether or not definitive recording has been performed. If it is determined that deterministic recording has been performed, the display control unit 122 proceeds to step S14.

  In step S14, the display control unit 122 displays the range of the seek bar 131 corresponding to the range of the program for which definite recording has been performed in red. If the program that is the subject of definitive recording is a program that is still being broadcast, the range from the broadcast start time position of the program to the broadcast position is displayed in red Is done. In addition, when a program that is a definite recording target is a program that has already been broadcast, the entire broadcast time range of the program is displayed in red. Thereafter, the process is terminated.

  If the display control unit 122 determines in step S13 that deterministic recording has not been performed, the display control unit 122 skips the process in step S14 and ends the process.

  While the follow-up reproduction is performed, the time represented by the entire seek bar 131 is appropriately switched by repeating the above processing. In addition, the user can intuitively grasp the range of the program on which definite recording has been performed in relation to the broadcast time of the program.

  Next, processing of the personal computer 1 that manages program data will be described with reference to the flowchart of FIG.

  This process is performed in parallel with the process of FIG. 16 and the process of FIG. 17 as appropriate. Similar to the processing in FIG. 16, for example, the processing is started when a predetermined channel is selected from the channels displayed on the list display unit 32 or when the channel is switched. When a predetermined channel is selected by the user, the data of the program being broadcast on the selected channel and the EPG data of the program are output from the reception control unit 121 to the display control unit 122, and the program being broadcast is reproduced. Done.

  In step S21, the reception control unit 121 determines whether or not to start temporary recording, and waits until it is determined to start temporary recording.

  The reception control unit 121 performs the temporary recording in step S21 because the “backward viewing function” setting has been enabled or the pause operation has been performed with the “backward viewing function” setting disabled. If it is determined to start, the process proceeds to step S22, and the data of the received program is output to the recording control unit 123 to perform temporary recording. The recording control unit 123 stores the program data supplied from the reception control unit 121 in the DB 124.

  In step S23, the data management unit 125 determines whether a follow-up reproduction of a predetermined program has been instructed.

  If the data management unit 125 determines in step S23 that chasing playback has been instructed, the process proceeds to step S24, where the data of the selected program is read from the DB 124, and the read data is output to the display control unit 122 to output the program. Let it play. The display 21 displays a video of a program selected by the user as a target for chasing playback.

  On the other hand, if the data management unit 125 determines in step S23 that chasing playback is not instructed, the process skips step S24 and proceeds to step S25.

  In step S25, the data management unit 125 determines whether or not there is a program that is temporally two previous on the basis of the program that is the target of the chase reproduction, and if it is determined that there is such a program, Proceed to step S26.

  In step S <b> 26, the data management unit 125 determines whether or not a predetermined time such as 1 minute has elapsed since the reproduction of the program that is the target of the chase reproduction is started, and until it is determined that the time has elapsed. stand by.

  If the data management unit 125 determines in step S26 that a predetermined time has elapsed since the start of the playback of the program that is the target of the chase playback, the data management unit 125 proceeds to step S27 and is the target of the chase playback. The data stored in the DB 124 of the program two times earlier in time with respect to the program is deleted.

  In step S28, the data management unit 125 determines whether or not the user has instructed to perform definitive recording of the program that is the target of the chase reproduction.

  If the data management unit 125 determines in step S28 that it has been instructed to perform definite recording, the data management unit 125 proceeds to step S29, and the program that is the target of the follow-up reproduction is automatically deleted from the target. Except for this, the program is recorded deterministically by managing it as a recorded program.

  On the other hand, if the data management unit 125 determines in step S28 that there is no instruction to perform definitive recording, the process of step S29 is skipped and the process proceeds to step S30.

  In step S30, the data management unit 125 determines whether or not the chasing reproduction is to be ended. When it is determined that the chasing reproduction is not to be ended, the processing after step S25 is repeatedly executed. If it is determined in step S30 that chasing playback is to be ended, the data management unit 125 ends the process.

  Viewing a program on the personal computer 1 is considered to be performed while performing some other work, and therefore, the user is often distracted by the work and often misses the scene he wanted to see. Where possible, the process as described above enables retroactive viewing of scenes that have been temporarily recorded, and enables recording (deterministic recording) in units of programs later. Thus, convenience for the user is achieved.

  Next, management of a list of receivable channels will be described.

  Since the personal computer 1 is a portable device, a user may watch a program in various regions having different receivable channels. Therefore, in the personal computer 1, a list of channels for each region can be stored. The list of channels is stored and managed in the DB 124 by the data management unit 125, for example.

  For example, if a user scans a channel in the first visited area and creates a channel list, the next time he visits the same area, he simply selects the channel list that was created in advance. Channel settings can be made without having to scan the channel again.

  FIG. 19 is a diagram illustrating an example of a screen used for setting a channel.

  The screen shown in FIG. 19 is displayed when the channel tab 151 is selected from the tabs of the setting window displayed when a predetermined operation is performed with the mobile TV application activated.

  The column of “registered channel list” displayed at the top of the screen of FIG. 19 is a column in which the name of the currently registered channel list is displayed. In the example of FIG. 19, a channel list identified by the name “Tokyo company” is registered (selected as a list to be used).

  In the “Create New” field displayed below the “Registered Channel List” field, a new creation button 161 that is operated when creating a new channel list is displayed. When the destination area is the first visited area, the user can create a list of channels that can be received in that area by pressing this new creation button 161.

  When the new creation button 161 is pressed, the channel is scanned. The user can set a name in a list in which channels of scan results are registered, and the list in which the name is set is a created list.

  The “channel setting” column displayed below the “new creation” column is a column in which information on the channel list that has been created is displayed. In this column, a channel list selection button 162, a channel information display unit 163, a registration button 164, and a delete button 165 are displayed.

  The channel list selection button 162 is a button operated when selecting a channel list for displaying information from the created channel list. In the example of FIG. 19, information on the channel list identified by the name “company in Tokyo” is displayed in the left column of the channel list selection button 162.

  When the channel list selection button 162 is pressed, as shown in FIG. 20, a list of names of the channel list already created is displayed below the channel list selection button 162 (below the column in which the list name is displayed). A list 171 is displayed. The user can select a channel list from those displayed in the list 171. In the example of FIG. 20, in addition to the channel list identified by the name “Tokyo company”, the channel list identified by the name “Osaka family” is displayed in the list 171 as a created list. .

  Returning to the description of FIG. 19, the channel information display unit 163 is a column in which information of channels registered in the channel list selected from the created list is displayed. In the example of FIG. 19, it is displayed that five channels 611CH, 621CH, 641CH, 661CH, and 681CH are registered in the channel list identified by the name “Company in Tokyo”. The name of each channel is also displayed.

  The registration button 164 is operated when registering a channel list selected from the created list as a channel list to be actually used. The delete button 165 is a button operated when deleting the channel list selected from the created list.

  For example, when a channel list identified by the name “Osaka's parents' house” is selected from the list 171 of FIG. 20 and information on the list is displayed on the channel information display unit 163, the registration button 164 is pressed. , A channel list identified by the name “Osaka's parents' home” is registered as a channel list to be actually used. At this time, the channel setting screen is as shown in FIG.

  In the example of FIG. 21, it is shown that a channel list identified by the name “Osaka's parents' home” is registered in the “registered channel list” column. Further, the channel information display section 163 in the “channel setting” column indicates that three channels 641CH, 661CH, and 681CH are registered in the channel list identified by the name “Osaka's family”. ing.

  By selecting a channel list that has already been created from such a channel setting screen, if the user performs only once when creating the channel list, there is no need to scan the channel at the destination each time.

  For example, in Tokyo, a program broadcast on five channels registered in the channel list identified by the name “Tokyo company” is registered by registering a channel list identified by the name “Tokyo company”. You can watch and broadcast in 3 channels registered in the channel list identified by the name of “Osaka's parents” by registering the channel list identified by the name of “Osaka's parents” in Osaka Can watch the program.
