Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information recording / reproducing apparatus which mainly records video data of digital television broadcasting such as CS broadcasting and BS broadcasting in a hard disk incorporated therein and records the title of a recorded program. The present invention relates to a method of displaying a list of the contents of the above on the screen of the monitor.

[0002]

2. Description of the Related Art In recent years, an information recording / reproducing apparatus using a hard disk has been provided as a recording medium for recording video data of such a digital television broadcast, instead of a conventional video tape (for example, Japanese Patent Laid-Open No. 11-1999). -4551
(See Japanese Patent No. 7). The hard disk can perform high-speed cueing and has a large capacity as compared with a video tape and the like, so that the recorded video data can be processed more quickly and appropriately.

In the above-mentioned digital television broadcasting, MPEG (Moving Picture) coded as digital information is used.
Image information and audio information in the Experts Group) format are transmitted as a broadcast signal, and this broadcast signal generally includes a table (additional data). In the information recording / reproducing apparatus, referring to the table, for example, information such as a title of a broadcast program, an ID unique to the program, a program genre, a program content, and program guide information such as a broadcast date and a broadcast time of a broadcast program are displayed. You can get it. Therefore, conventionally, when a broadcast program is recorded, program data such as a title, a program genre, a program content, a broadcast date and a broadcast time related to the broadcast program are associated with video data of the broadcast program to be recorded on a hard disk. A technique for storing the image data in a storage area different from the storage area of the video data has been devised.

The stored program data are read from the storage area of the hard disk and displayed on the monitor as a list when the user (user) performs an operation to instruct the display. FIG. 5 is a list of program data displayed on the monitor screen. This allows the user to
While referring to the list of program data displayed on the monitor screen, select the desired program from the various recorded broadcast programs, move the selection cursor to the selected title or subtitle, and then press the Enter key. By pressing, the video data of the broadcast program of the selected title or subtitle can be reproduced.

In the conventional display of program data, that is, recorded contents, as shown in FIG. 5, for a certain title displayed in the title display field D1, all subtitles having the same title are displayed as subtitles. The information is sequentially displayed in the column D2, and the information about the program genre, the program content, the broadcast date, and the broadcast time corresponding to each subtitle is displayed in the corresponding display columns D3 to D6. FIG. 5 shows that, for example, the broadcast program of "title 1" that is broadcast every week is recorded for 3 weeks, and the "subtitle" added to each lap of the broadcast program of "title 1" is shown. 1-1, 1-2, 1-
3 ”is displayed together with the program genre, program content, broadcast date and broadcast time related to this.

[0006]

However, in the conventional recording content display method, broadcast programs having the same title but different subtitles are collectively displayed. Therefore, in the example of FIG. 5, one program is displayed on one screen. Only three types of titles can be displayed in the list. Moreover, if a weekly broadcast program is recorded each time, the number of titles that can be displayed in the list on one screen will be further reduced, and the information related to a certain title will be duplicated. Occasionally, it will be divided into two screens and displayed. Therefore, the user may have to repeat the screen switching operation before finding the desired title, which is troublesome before selecting the desired title to be reproduced.

In order to solve the above-mentioned problems, conventionally, it is possible to reserve a program for recording a television broadcast from a remote place, and to record a list of reserved and recorded programs to a user automatically. A reservation device and a program recording result display device (see Japanese Patent Application Laid-Open No. 2000-350142), a video recording content confirmation method for supporting the confirmation work of the video recording content and reducing the time required for the confirmation (Japanese Patent Application Laid-Open No. H11-11). No. 185,451) has been proposed. However, these techniques cannot confront the above-mentioned problems. That is, in the former case, there is only a description of “display recorded program guide data on a display device by application software”, and no specific display control means or display example is disclosed. It does not help to devise means. On the other hand, the latter is to reproduce and view still images recorded at the same time as the recording of the video signal, mainly when confirming the recorded video at the broadcasting station, and is useful for creating an effective list display of the recorded contents. Useless.

Therefore, the present invention has been made in view of the above conventional problems, and provides a recording content display method capable of displaying as many titles as possible in a list that can be displayed on one screen. The purpose is to do.

[0009]

In order to achieve the above object, the recorded content display method of the invention according to claim 1 is for displaying a list of recorded contents such as titles of recorded programs on a monitor screen. When the digital broadcast signal is recorded on the recording medium, the title of the recorded broadcast program and the number of recorded titles are stored in the first storage area of the recording medium, and the accompanying information of the title is stored. When the program is recorded in the second storage area of the recording medium and an instruction to display the program content is made, first, the stored content of the first storage area is read out and displayed on the screen. It is characterized in that, when an instruction to select and determine a title is issued, the supplementary information related to the selected title is read out from the second storage area and displayed.

In this recording content display method, first, only the title and the number of recorded titles are displayed. Therefore, many titles can be displayed as a list on one screen, and the user can find a desired title. Since the number of switching operations of the display screen required is significantly smaller than that of the conventional display method, the desired title can be found quickly. After the title is found out from the display screen and the selection is decided, only the incidental information related to one selected title is displayed, so even if many broadcast programs with the same title are recorded, for example. Since the supplementary information related to the title can be collectively displayed on one screen, the user can easily find the supplementary information on the desired title from the one screen.

According to the second aspect of the present invention, in addition to the configuration of the first aspect, recorded video data is a digital broadcast signal including program data,
The title and incidental information of the program data are automatically recorded in the first and second storage areas when the video data is recorded.

According to this structure, when the user gives an instruction to record the broadcast program, the title and the incidental information of the program data are automatically recorded, so that the user forgets the operation of recording the title and the incidental information. It is possible to reliably prevent the occurrence of a defect such as a recording failure.

Further, in the recorded content display method of the invention according to claim 3, when a list of recorded contents such as titles of recorded programs is displayed on a monitor screen, a plurality of broadcast programs recorded in a recording medium are recorded. The storage unit includes a storage unit that stores a title and its accompanying information and a counting unit that counts how many same titles are recorded in the storage unit. Only one is displayed, and the number counted by the counting unit is displayed together with the title.

In this recording content display method, for example, when the broadcast program of the same title that is broadcast every week is continuously recorded, the recorded content of the title is left as it is and only the total number of the titles is newly counted. Since it is only necessary to update and store the supplementary information of the title, it is possible to simplify the control process for updating the recorded content. When displaying a list of recording contents on the screen, only one of the same titles is displayed and only the number of supplementary information related to the titles is displayed. It is possible to simply display a large number of titles on a single screen as a list, which allows the user to easily and quickly find a desired title.

Further, in the recorded content display method of the invention according to claim 4, it is preferable that the storage section in the invention according to claim 3 is a storage area of a recording medium. According to this configuration,
The video data of a plurality of broadcast programs, the title and all the information of the title additional information, the storage area of the recording medium,
For example, since the data is stored in a storage area of a large-capacity hard disk built in a recent information recording / reproducing apparatus, the content of the recording is displayed as compared with the case where the title and its accompanying information are separately stored in RAM or the like. The control process of is simplified.

[0016]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a block diagram showing an information recording / reproducing apparatus which embodies a recording content display method according to an embodiment of the present invention. In the figure, a digital broadcast receiving apparatus is illustrated. A digital broadcast signal sent from a broadcast station is received by an antenna 1, and this received signal is input to a broadcast receiving unit 2 having a tuner circuit and the like. The broadcast reception unit 2 selects a reception channel and inputs the reception signal of the selected broadcast channel to the digital demodulation unit 3.

The digital demodulation section 3 performs information separation of the multiplexed reception signal, and decodes the separated video information and audio information by a video decoder and an audio decoder, respectively, to obtain video data and audio data. . The video data is displayed on the screen of the monitor 7, and the audio data is converted into audio by the speaker 4 and output.

The control unit 8 for controlling the operation of the entire apparatus includes
Various key operation signals are input from the key input unit 13, and various key operation signals transmitted from the remote control transmitter 17 are input after being received by the remote control receiving unit 14. When the user performs an operation of instructing recording (including a case of recording reservation) by a key operation of the remote control transmitter 17, the control unit 8 has a tuner circuit of the broadcast receiving unit 2 to receive the digital broadcast of the recording channel. Are synchronized with each other to receive the digital broadcast signal (video data) of that channel. This video data is sent to the digital demodulation unit 3
And is recorded (recorded) in the video data storage area 10a of the HDD (hard disk drive) 10 as a recording medium via the interface unit 9.

By the way, a digital broadcast signal generally includes an electronic program guide (EPC) as program data, and this electronic program guide is character data sent by being superimposed on a digital broadcast, It is composed of a program title, a program genre, an outline of program contents, a broadcast date, a broadcast time, and the like. In the past, the program data was stored in a predetermined storage area of the HDD 10 via the interface 9, but in this embodiment, the control unit 8 receives a recording instruction by a key operation signal of the remote control transmitter 17. At this time, the program data extraction unit 11 is instructed to extract only the program data from the digital broadcast signal, and the title of the extracted program data is HD.
It is controlled so as to be stored in the main storage area 10b of D10 and other auxiliary information in the sub storage area 10c of the HDD 10. Details of this will be described later.

Further, when the control section 8 receives an instruction to display the recorded contents by the key operation signal of the remote control transmitter 17, the control section 8 reads the title from the main storage area 10b and displays it on the monitor 7 via the display control section 12. And let
When a further display instruction is received by the key operation signal, the supplementary information of the program data is read from the sub storage area 10c and displayed on the monitor 7 via the display control unit 12.
Details of this will be described later.

Next, when recording, the program data is stored in the HDD.
The control processing stored in 10 will be described with reference to the flowchart of FIG. The control unit 8 constantly monitors the user's instruction to record the broadcast program by operating the remote control transmitter 17 based on the input from the remote control receiving unit 14 (step S1), and when the recording instruction is issued, The video data decoded by the digital demodulation unit 3 is recorded in the video data storage area 10a of the HDD 10 through the interface 9, and the program data is extracted from the data decoded by the digital demodulation unit 3 to the program data extraction unit 11. Command to extract only (step S
2).

Subsequently, the control unit 8 controls the program data extraction unit 1
It is searched whether the same title as the title of the program data extracted by 1 is stored in the main storage area 10b of the HDD 10 (step S3). When the same title is stored in the main storage area 10b, "1" is added to the number stored in the storage area of the title in the main storage area 10b to calculate a new number, and The calculated number is updated and stored (step S4). After that, the control unit 8 displays supplementary information such as a subtitle related to the title (the broadcast order of the title if not particularly attached), program genre, program content, broadcast date, broadcast time, and the like. , Is stored in a predetermined storage area provided in the sub storage area 10c corresponding to the title (step S
5). The predetermined storage area is set, for example, in association with an ID unique to the broadcast program.

On the other hand, when it is determined that the same title is not stored in the main storage area 10b (step S
In 3), the title is newly added and stored in a predetermined storage area of the main storage area 10b (step S).
6). After that, the control unit 8 stores the supplementary information of the title in a predetermined storage area provided in the sub storage area 10c corresponding to the title (step S7).

Next, the main storage area 10 of the HDD 10
The control process for displaying the storage contents of the sub storage area 10c and the sub storage area 10c will be described with reference to the flowchart of FIG. The control unit 8 constantly monitors whether or not the user has instructed the display of the recording content by operating the remote control transmitter 17 when selecting and reproducing desired one of the video data recorded in the HDD 10 (step S11). ), When it is determined that the display of the recorded content is instructed, the stored content of the first file in the main storage area 10b is read and the monitor 7 is instructed via the display control unit 12 to display the screen. The file here is a set of information that is created in the main storage area 10b by the program, in other words, a set of information that can be displayed as one screen on the monitor 7.

FIG. 4A shows an example in which the data read from the main storage area 10b is displayed as a recorded program list. Since this list has only the title display column D11 and the title number display column D12,
Many titles can be displayed as a list on one screen. For example, the number of titles that can be displayed on one screen of the monitor 7 is three as shown in FIG. 5 in the conventional display method, but is increased to eight in this embodiment.

After displaying the data in the main storage area 10b as a recorded program list, the control unit 8 waits for the user to select and determine a desired title (step S13). When the user cannot find a desired title in the recorded program list displayed on the screen, the user operates the remote control transmitter 17 to instruct to change the screen display. When the control unit 8 determines that a display change instruction has been issued (step S14), the main storage area 10b
The storage content of the file next to the file being displayed in step S15 is read out and displayed on the monitor 7 (step S15). The user repeats the instruction to change the display until he or she finds a desired title. In this case, the number of titles displayed on one screen of the monitor 7 (eight in this embodiment) is large. Since the number of times of switching the display screen required to find the desired title is significantly smaller than that of the conventional display method, the desired title can be found quickly.

When the user finds a desired title in the list of recorded programs being displayed, he or she moves the selection cursor to the title being displayed and then operates the enter key of the remote control transmitter 17. Then, an instruction to select and determine a desired title is given. The control unit 8 that has determined that the title has been selected (step S13) reads the supplementary information related to the selected title from the storage area corresponding to the title in the sub storage area 10c, and monitors it via the display control unit 12. 7 is displayed on the screen (step S16). The designation of the storage area to be read in the sub storage area 10c is performed by the instruction of the ID unique to the broadcast program, that is, the title.

FIG. 4B shows an example in which the data read from the sub storage area 10c is displayed as a recorded program list. The display contents when "Title 1" is selected are shown in the figure as an example. In this list, the title display column D13, subtitle, program genre, program content (outline), broadcast date and broadcast time are shown. Each display column D14 ~
It has D18. Since this list only displays the supplementary information related to one title, for example, even when many broadcast programs of the same title (for example, up to eight can be displayed in this example) are recorded, Since they can be collectively displayed on the screen, the user can easily find the subtitle in the desired title.

The control unit 8 controls the display of the recorded program list based on the supplementary information, and then waits for the user's instruction for reproduction (step S17).
When the user finds a desired subtitle in the recorded program list in which the supplementary information is displayed, the user moves the selection cursor to the subtitle and moves it to the subtitle, and then operates the remote control transmitter 17 to instruct the reproduction. . As a result, the control unit 8 determines that a reproduction instruction has been issued, and then controls the video data corresponding to the instructed subtitle to be read from the video data storage area of the HDD 10 via the interface 9 and reproduced on the monitor 7. (Step S18).

[0030]

As described above, according to the recorded content display method of the present invention, since only the title and the number of recorded titles are displayed first, many titles are displayed as a list on one screen. The number of display screen switching operations required for the user to find the desired title is
Compared with the conventional display method, the number is much smaller, and the desired title can be found quickly. After the title is found in the display and selected, only the additional information related to one selected title is displayed.For example, even if many broadcast programs with the same title are recorded, Since the incidental information related to the title can be collectively displayed on one screen,
The user can easily find the supplementary information in the desired title.
