Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recorded program information processing apparatus for digitally recording / reproducing video data such as past broadcast programs and broadcast program information on a digital disk whose capacity is rapidly increasing. The present invention relates to a recorded program information processing apparatus that displays an electronic program guide (EPG: Electronic Program Guide) intuitively and easily based on a reproduction time.

[0002]

2. Description of the Related Art As a prior art for providing a program guide for a recorded program recorded in the past, Japanese Patent Laid-Open No. 10-42 is disclosed.
No. 242 is known. The technology described in the publication discloses a program guide for a recorded program in order to handle an electronic program guide (hereinafter, referred to as an EPG) superimposed on a broadcast signal and an EPG representing a table of contents of the recorded program in an integrated manner. This is a technology for unifying the program guide of a broadcast-scheduled program and the program guide of a recorded program on the same screen, displaying them in a multi-window system, and facilitating user operations.

[0003]

However, Japanese Patent Application Laid-Open No.
The technique described in Japanese Patent No. 42242 is merely a technique as an apparatus for creating and displaying a recorded program guide, and has the following problems when applied to an apparatus for reproducing a recorded program. First, it is not clear how to display the time axis of a recorded program table in the technology described in the publication. That is, assuming that the recorded program information is recorded in a required portion of the VTR, the reproduction time (broadcast time) data recorded in the VTR is considered to be the time at the time of recording or the length of the broadcast time. The time at the time of the display cannot be reflected in the recorded program guide. That is, when the recorded program guide is displayed, the reproduction time is applied to the current time and is not displayed on the real time axis. For this reason, the program guide displays a program guide based on the time based on the recording date and time or the playback time length of the recorded program in hours and minutes, which may cause confusion for users. is there.

Further, the technology described in the above publication discloses that a table of contents representing the contents of a recorded video is stored in a specific portion such as a head portion of a recording medium, and a program table of the recorded program is prepared. Even if the program guide of the recorded program is displayed during the reproduction of, all the recorded programs are described in the program guide in the same manner as displayed before the reproduction. For example, if a program guide of a recorded program is displayed when a certain one-hour program is reproduced / viewed for 45 minutes, the program should have the remaining time required for reproduction, 15 minutes, described in the program guide. This is a matter of course considering that the electronic program guide (EPG) is used for the user's program viewing plan. However, the technique described in Japanese Patent Application Laid-Open No. 10-42242 is not originally a technique as a reproducing apparatus, and thus no such display method is mentioned at all. Even though the user has finished viewing most of the recorded programs, the recorded program table displays all the recording times, and cannot know when it is time to view all of them.

[0005] The same can be said not only when the program table during the reproduction of the recorded program is displayed, but also when the recorded program is reproduced and viewed halfway and the reproduction is stopped. In other words, if a recorded program is played back halfway and stopped, and the program guide is displayed later, the remaining part of the recorded program is described in the program guide from the middle of the point at which playback was stopped, so that the user can intuitively remain. You should be able to see the time.
In the technique described in Japanese Patent Application Laid-Open No. 0-42242, the recorded program data is originally stored in the medium (VTR) on which the recorded video is recorded as described above, and there is no mention of rewriting the recorded program data. Because there is no
Even if the program is reproduced / viewed partway, the next time the program guide is displayed, the entire program is displayed again, and there is a problem that the user cannot make a correct viewing plan.

[0006] Therefore, the present invention is to solve the above-mentioned problem, and an object of the present invention is not to display the reproduction time in the length of time when recording and viewing a video program. Instead, it is an object of the present invention to provide a program guide of a recorded program that can be intuitively recognized as the viewing end time of the reproduced program by displaying the actual time starting at the present time. In addition, when the recorded program guide after the playback is stopped in the middle or the currently-recorded program guide is displayed, the remaining playback time is calculated by subtracting the program playback / viewing time from the time required for all playback. It is an object of the present invention to provide a program guide that allows the user to intuitively know when the recorded program is viewed to the end by displaying the program program. Furthermore, in a recording device that records a large number of programs on a large-capacity digital medium, an approximate value of the time length that can be additionally recorded is displayed in a recorded program table, so that it is possible to intuitively determine how many remaining programs can be recorded. Is to provide a program guide that can be known to the public.

By doing so, the playback time of the recorded program is displayed intuitively with respect to the real time axis at the time of displaying the recorded program guide instead of the length of time, and it is intuitive to see what time it will be when the recorded program is viewed to the end. You can know.

According to a second aspect of the present invention, there is provided the recorded program information processing apparatus further comprising an additional writable time calculating means for calculating a recording time length which can be additionally recorded in the program information recording means. The display control means displays at least one of the calculated time required for reproduction of the recorded program and the calculated recording time length that can be additionally recorded, so that the user can display the program for how long. You can intuitively know whether you can record.

According to a third aspect of the present invention, in addition to the first aspect of the present invention, the reproduction time of the recorded program is measured, and the measured reproduction time is transmitted to the program information recording means as needed. Equipped with a reproduction timing storage means for recording;
When the display control means displays the recorded program guide in a state where the recorded program is reproduced halfway, or in a state where reproduction is stopped halfway, the corresponding area of the recorded program table is reduced and displayed by the reproduction time. Therefore, when displaying a “recorded program guide” after playing back a recorded program or after stopping during playback, intuitively know the time required to view all the rest of the program that has been played back halfway. Can be.

According to a fourth aspect of the present invention, there is provided a recorded program information processing apparatus further comprising a program selecting means for selecting a desired program from the recorded program table, in addition to the recorded program information displaying apparatus of the third aspect. When a recorded program that has been reproduced halfway is selected, the display control means reproduces the part of the recorded program that has been viewed halfway since the last time the reproduction was completed. it can.

According to a fifth aspect of the present invention, there is provided the recorded program information display apparatus according to the third aspect, wherein the reproduction time of the recorded program obtained by the reproduction time storage means is equal to the time required for reproducing the entire recorded program. If they are equal, the display control means suppresses the display of the recorded program, so that the "recorded program guide" always displays only the program that the user actually watches, and gives priority to the recorded program that the user wants to view. Can be displayed.

According to a sixth aspect of the present invention, there is provided a recorded program information processing apparatus, further comprising: a recorded program information deleting device for deleting a recorded program; and a recorded program information deleting device for deleting recorded program information.

RAM drive). The broadcasting system to which the present invention is applied includes a communication system such as the Internet and CS broadcasting that can be simultaneously received by a plurality of terminals, and includes not only a video broadcasting system but also a text broadcasting system and an audio broadcasting system. But
Any system that can broadcast an electronic program guide (EPG) by being superimposed on broadcast content can be used.

The remote control 100 includes a recording start switch 10
1. Recorded program guide display switch 102, recorded program deletion switch 103, cursor movement switches 104 to 107 for moving a selection cursor when an option is displayed on the display device 11 of the main body 10, and recorded program reproduction switch 108 , A recorded program playback stop switch 109, which is pressed when the user requests a desired function,
The corresponding command is transmitted from the light emitting unit 110. The operation of the system for each request will be described later.

FIG. 2 shows a block diagram of the recorded program information processing apparatus. After the program information signal and the signal of the program itself are received by the receiving antenna 12 and demodulated by a tuner (not shown), when the user presses the recording start switch 101, the program information is stored in the program information recording unit 22, and The program recording means 21 converts the data of the program content itself into MPE data.
The image data is compressed by a G (Moving Picture Experts Group) 2 method and recorded on a recording medium 30 such as a DVD by the external storage device 18.

The display control means 23 includes a remote control light receiving unit 16
Button switch 1 of remote control 100 received via
In accordance with the instructions 01 to 109, the current time is acquired from the time acquisition means (clock) 17, the program table of the recorded programs is acquired from the program information recording means 22, and the recorded program is acquired from the program recording means 21. Then, the recorded program is reproduced from the respective data using the recorded program reproducing means 24, the time required for reproduction is calculated using the reproduction time length calculating means 25, and the additional writing is performed using the additional writable time calculating means 26. The possible time length is calculated, and is displayed and controlled on the display device 11 of the main body 10 of the recorded program information processing apparatus. However, the recorded program reproducing means 24 is dedicated hardware for decompressing the recorded compressed data of the MPEG2 format, and manages the time of reproduction and viewing using the reproduction time storage means 27, and the viewing management in the program information recording means 22. Create and update files. Thereafter, the display control means 23, the reproduction time storage means 27, the recorded program reproduction means 24, the reproduction time length arithmetic means 25, the additional writable time calculation means 26, and the recorded program deletion means 28,
The recorded program information deleting means 29 is collectively called a system.

Next, a program recording means for recording a program will be described with reference to FIG. Since the recorded program information processing apparatus of the present invention is an apparatus for displaying and presenting recorded video content, when recording a program, the program information of the recorded program is simultaneously read from the program information in preparation for the display of a recorded program table described later. It is stored in the recording means 22. FIG. 3 shows an operation flow when the apparatus starts recording and ends recording. The user has the remote control 10
0 recording start switch 101 is depressed (step 1),
When receiving the recording command from the light receiving unit 16, the receiving antenna 1
2 and program information and program information are obtained via a tuner (not shown) (step 2). The system controls the program recording means 21 and the program information recording means 22 so that the DVD
And the like, and the program information is recorded in the compressed data format on the external storage medium 30 and the program information in the same format (step 3). The channel for recording uses a cursor movement switch on the remote controller 100, that is, when the upper switch 104 is pressed, the receiving channel is set to one.
When the down switch 105 is depressed, the number increases by one channel.

When the recording start switch 101 is pressed,
The user starts recording the channel / program selected and received by the upper switch 104 and the lower switch 105. At this time, the system decodes the selected channel number and program name from a predetermined position in the electronic program guide data format and saves them in the program information recording means 22 (step 3), and acquires the recording start time from the time acquisition means 17 Is recorded on the program information recording means 22 (step 4). These recorded program information is managed by generating a management format file as shown in FIG. The format of FIG. 4 will be described later in detail.

As described above, the system that has started recording continues recording until the stop switch 109 is pressed. When there is no more recording area in the system (steps 5 and 6), or when the stop switch 109 is pressed (step 5), the recording end time is obtained from the time obtaining means 17 (step 7). After subtracting the recording start time, the recording time (the time length required for reproduction) is stored in the recorded program information management format file of FIG. 4 (step 8). Further, the data size of the recorded program is obtained, the smallest unused number among 0001 to 9999 is set as a file name, and both are stored in the recorded program information management format (steps 9 and 10).

FIG. 4 is a diagram showing an example of a recorded program information management format file. This table shows the recorded program names 64
Bytes, playback time 4 bytes, viewing situation 4 bytes, start frame 8 bytes, data size 8 bytes, file name 8
It is a table of 96 bytes per byte program. Further, a NULL character is added to each parameter in the last column. As described above, the recorded program name is EPG at the start of recording.
, And the playback time, data size, and file name are recorded at the end of recording. The viewing status indicating the reproduction time when the reproduction / viewing is performed halfway, and the next start frame number when the reproduction is stopped halfway are parameters stored by the system at the time of the reproduction operation, and will be described later with reference to FIG. By the way, for a recorded program that has not been played and viewed at all, the start frame is 000000.
1. The viewing situation is 00 hours and 00 minutes.

FIG. 5 is a diagram showing a processing flow of the recorded program viewing management means. The user presses the right switch 106 and the left switch 107 of the remote controller 100 from the recorded program table (FIG. 8) displayed on the display device 11 of the main body 10 to select a desired recorded program.
08 (step 21), the system controls the recorded program reproducing means 24 and the recorded program information recording means 22.
Then, the reproduction start frame number is obtained from the management file (FIG. 4) stored in the storage device, and the recorded program content is reproduced from the program recording means 21 (step 22).

As described above, since the program contents stored in the program recording means 21 are compressed by, for example, MPEG2, the recorded program reproducing means 24 is dedicated hardware for decoding the MPEG2 signal, and decodes in real time. The data is transmitted to the display control means 23 and reproduced and displayed from the k-th frame of the start frame (step 2).
2) The value k of the frame counter is incremented by 1 and written into the management file (steps 23 to 25). At this time, the frame counter k counts the number of the currently decoded frame and transmits the frame to the sequential reproduction time storage unit 27. The reproduction time storage means 27 counts the I frame number currently decoded by the recorded program reproduction means 24 and the length of time during which the recorded program reproduction means 24 reproduced the program, and stores the result as a recorded program stored in the program information recording means 22. Write sequentially to the management file (FIG. 4). That is, in the MPEG2 compression method, there are an I frame, a B frame, and a P frame, whereas the I frame is a capture frame of the entire screen,
Since the B frame and the P frame are each difference frames, when playing back from the middle, it is efficient to play back from the I frame closest to that point.

Until the recorded program is viewed until the end, that is, until the recording end point, or until the user presses the stop switch S4, k is recorded in the recorded program management file (FIG. 4) for each I frame (FIG. 4). Step 24, Step 25). Play the recorded program to the recording end point,
Alternatively, when S4 is pressed by the user (step 24), the last playback time (in this case, equal to the playback time of the entire recorded program) and the last decoded frame number are written to the recorded program management file, similarly to the above routine. Ends the reproduction process (steps 24 and 26).
Incidentally, when the recorded program is reproduced to the recording end point, the reproduction time is equal to the time of the viewing situation.

The means for displaying the recorded program guide will be described with reference to FIG. When the user presses the recorded program guide display switch 102 on the remote controller 100 (step 3).
1), the system reads the recorded program management file shown in FIG. 4 into an appropriate buffer area of the random access memory provided in the display control means 23 (step 32). When the user is playing back the recorded program, as described in the processing flow shown in FIG. 5, the recorded program management file records the number of frames reproduced and the reproduction time length up to that point.

Here, as shown in FIG. 8, the display of the program information to be displayed at the left end of the recorded program table displayed on the display device 11, that is, the portion closest to the present along the real time axis will be described. I do. If you are currently playing a recorded program,
The playback program is displayed first (step 33, step 3
4). At this time, the currently reproduced program is displayed first from the data of the recorded program management file of FIG. 4 (the display flow is shown in FIG. 7).
Later). After the display, the record of the currently reproduced program is deleted from the recorded program management file (FIG. 4) in the buffer (step 35), and the recorded program information thereafter is shifted upward. If the currently recorded program is not being reproduced, the program with the oldest start date is displayed. In this display method, similarly to the case where the recorded program is being reproduced, the displayed oldest recorded program is deleted from the recorded program management file read into the buffer, and the subsequent program information is shifted up one line (step 3).
6). This display flow is shown in FIG. 7 and will be described later.

The present system acquires the current time at the time of displaying the recorded program table based on the reproduction time of the recorded program table, and displays each recorded program on a real time axis starting from the current time. Therefore, the system obtains the current time from the time obtaining means 17 and obtains the playback time length from the data of the recorded program management file of FIG. The addition is performed on the real time axis, and the reproduction end scheduled time is displayed on the display device 11.

These operations are repeated (steps 37 to 37).
40) The second and subsequent recorded programs are all displayed in order from 1 in the column order of the recorded program management file. Until the display of all programs is completed or the display of the recorded program guide display screen (FIG. 8) is completed to the left end, that is, the scheduled reproduction end time of the display-recorded program determined by the display flow of FIG. The display is repeated until it becomes equal to or greater than the latest time Tmax (right end of the screen) at which the program guide can be displayed.

Thereafter, the remaining data size is obtained from the sum of the file sizes for these programs (step 41). The method of obtaining is very simple, for example, DVD-RAM
Is subtracted from the standard storage capacity of 5.2 GB, which is the total file size of recorded programs. Next, the system calculates how long the program can be recorded from the remaining data size. As described above, since the MPEG2 system is adopted as the image recording system in the present system, an hourly video with an average bit rate of 4 Mbps can be recorded at about 3.0 GB. Using this relationship, if the remaining data size is XGB, the approximate remaining recordable time T is obtained by the remaining recordable time T = X / 3.0 (hours) (step 42). Here, the rectangular area representing the length of the obtained T is displayed in the same manner as when displaying the program rectangular area (FIG. 7) (step 43), and the process is terminated.

However, MPEG2 employs a variable bit rate system, and automatically changes the bit rate between a screen with little movement and a screen with strong movement. For this reason, the remaining recordable time T differs depending on the image to be recorded, and cannot be obtained accurately. However, in this apparatus, a sufficient display effect can be obtained by obtaining an approximate value of whether the remaining recordable time length is 1 hour or 10 hours.

Next, means for displaying a program rectangular area will be described with reference to FIG. According to FIG. 6, the program area,
Alternatively, each of the free time regions is a rectangular region, and the reproduction time is represented by the area thereof. First, the viewing status of the program to be displayed is determined from the recorded program management file read into the buffer area (step 51). That is, FIG.
If the viewing status in the recorded program management file shown in FIG.
Return to That is, the program viewed until the end is not displayed on the recorded program guide. If the viewing situation is not equal to the playback time, the remaining playback time of the program is calculated as follows (step 52). Remaining reproduction time = (program reproduction time)-(viewing situation) From this remaining reproduction time, the size of the rectangular area to be displayed is obtained (step 53). That is, the maximum time for displaying the program guide is T (time), the width from the left end to the right end of the program guide is a (cm), and the reproduction time length of the recorded program is b.
Assuming (time), the width w (cm) of the rectangular area can be expressed as follows. w = ab / T (cm) The height of the rectangular area is a constant value c (cm).

As described above, the rectangular area is obtained, and the rectangular area of the recorded program to be displayed is displayed left-justified (step 54). Furthermore, if the displayed program is the leftmost program, the current time is set to the scheduled playback start time in the program table, otherwise, the playback time of the program to be displayed is set to the scheduled playback end time of the recorded program displayed immediately before. By adding the length, the reproduction end time is displayed on the upper right end of the rectangular portion (step 5).
5). An example is shown in FIG. FIG. 9 shows an enlarged view of each program rectangular part and the empty area rectangular part. That is, it is represented by a rectangular part having the above-mentioned vertical and horizontal lengths, and in each rectangular area, the program name, recording start date, and reproduction time length are described at regular intervals from the top for the recorded program, and For 9, “free space” and remaining recordable time length are displayed.

Finally, the processing associated with the erasure of the program content will be described with reference to FIG. When a user deletes a recorded program, the recorded program information needs to be deleted from the recorded program management file. That is, while the recorded program table is displayed on the display device 11, a recorded program to be deleted is selected by the right switch 106 and the left switch 107,
When the recorded program deletion switch 103 is pressed (step 6)
1) The system deletes the program from the program recording means 21 (step 62), and at the same time, deletes the program information from the program information recording means 22 from the recorded program management file (FIG. 4). All lines are deleted (step 63).

[0034]

As is apparent from the above description, according to the present invention, it is possible to provide a program guide of a recorded program which is more convenient when mainly recording and viewing a video program. . That is, according to the first aspect of the present invention, the playback time of the recorded program is displayed not by the time length but by the size of the area, and is displayed intuitively on the real time axis at the time of displaying the recorded program guide. It is possible to intuitively know when the recorded program will be watched to the end. According to the invention of claim 2, the user can intuitively know how long the user can record the program on the recording medium.
