[Prior art]

 Recently, as a recording medium for recording digital broadcast signals such as CS broadcasts and BS broadcasts, a video recording / reproducing apparatus using a hard disk instead of a conventional video tape has been provided.

When recording video data such as a digital broadcast signal on such a hard disk (hereinafter referred to as recording in this specification), much more video data is recorded than when recording on a conventional video tape. Can be recorded. Therefore, when a user tries to reproduce desired video data, many program titles and the like are displayed on a reproduction menu screen, and it is necessary to select a desired program (video data) from among them. .

[0004] Further, many broadcasted programs are broadcasted in a series such as daily or weekly, and are broadcasted at regular intervals. Can be recorded sequentially.

However, when reproducing a program recorded by such a series recording reservation, the user once displays a list of recorded programs on a reproduction menu screen as in the related art, and selects a list from among the programs. It was necessary to find the program of the desired series, select it, and play it.

[0006] In this case, although the program of the series can be sequentially recorded by the series recording reservation, the program menu is displayed on the playback menu screen in the order of recording, so, for example, the first episode of the series (A) If another program (B) is recorded between (A1) and the second episode (A2), the program name is displayed on the playback menu screen, such as "A1, B, A2 ...". Is done. Therefore, when the user wants to watch the first episode and the second episode of the series A, it is necessary to individually select A1 and A2 displayed discretely from the reproduction menu screen, which is a troublesome operation. Was.

Meanwhile, a technique for making a recording reservation of a series of programs in consideration of reproduction is disclosed in, for example, JP-A-2001-266457. In this prior art, after automatically recording broadcast data of a reservation number on a new track of a disc, the table information of the new track is added to the table of contents information of UTOC (User Table Of Contents) information stored in the RAM. I do. Then, on the RAM, the table of contents information of a plurality of tracks (video data) is continuously reproduced based on the video data attribute, for example, the program name or the pair of the day of the week and the recording start time. And so on. Thereafter, the UTOC information on which the table of contents information has been rearranged is written to the UTOC area of the disc. This allows the user to continuously reproduce and view the same program (series program) for a plurality of weeks, for example, without performing operations such as skipping.

[0008]

[Problems to be solved by the invention]

 However, according to the prior art described in the above publication, in order to continuously play back a series program, it is necessary to periodically rearrange the table of contents information and rewrite the UTOC area of the disk. There was a problem that the operation became complicated.

The present invention has been made to solve such a problem, and its purpose is to easily manage a series of programs without performing complicated processing such as rewriting of a UTOC area. It is an object of the present invention to provide a video recording / reproducing device capable of performing such operations.

[0010]

[Means for Solving the Problems]

A series number and a series serial number indicating the number of the broadcast in the series are given to the serialized video data to be broadcast, and the assigned series number and series serial number are added to the table of contents information of the video data. Means for creating series information associated with the series, storage means for storing the series information created by the series information creating means, and serialized video data recorded on the prerecording / reproducing disc. When playing back video data, the series information stored in the storage means is read and displayed, and the displayed series is displayed. Control means for reading out and reproducing the relevant video data from the pre-recording / reproducing disc based on the table of contents information associated with the desired information to be reproduced from the information. It is characterized by having.

[0011] The series information creating means may be configured such that, when a recording reservation of the serialized video data is selected, whether or not the series recording reservation is the first reservation is stored in the series information stored in the storage means. If it is a series recording reservation that has been made for the first time, a new series number will be added to the video data for which series recording has been reserved, and a series connection indicating that this is the first broadcast in the series. Number, and the series number and series serial number thus created are stored in the storage means while new series information is created in association with the table of contents information of the video data and stored in the storage means. If it is the series information stored in the means, the series number included in the series information and the largest serial number within the series number Then, a new series information in which the new serial number obtained by adding +1 to the serial number is associated with the index information of the video data is created and stored in the storage means.

[0012] When only a series number desired to be reproduced is selected from the displayed series information, the control means transmits the table of contents information associated with the series serial number included in the series number. The video data of the corresponding series number is sequentially read from the pre-recording / reproducing disc in ascending order based on the series serial number and reproduced.

According to the present invention having such a feature, at the time of recording reservation, only the series recording reservation is selected, and the series information creating means associates the series number, the series serial number, and the table of contents information with the series information.

The operation is exactly the same as that of a conventionally well-known video recording / reproducing device, and a detailed description thereof will be omitted.

Next, in the video recording / reproducing apparatus having the above configuration, (1) a reservation processing operation when a user makes a series recording reservation of series video data (particularly, a series information storage processing operation). ) And (2) a reproduction processing operation for reproducing video data recorded in a series.

(1) A reservation processing operation (particularly, a series information storage processing operation) when a user makes a series recording reservation of a series of video data will be described with reference to a flowchart shown in FIG. I do.

When the user operates the selection key 13 a of the remote controller 13, the key operation signal is received by the key receiving unit 12 and input to the control unit 10. When receiving the key operation signal, the control unit 10 displays a selection screen (not shown) for selecting either recording or reproduction on the screen of the monitor 8.

The user operates the move keys 13b1 to 13b4 while looking at the selection screen to move the cursor on the screen to the position described as “recording” and operates the enter key 13b5. This key operation signal is received by the key receiving unit 12 and input to the control unit 10. When receiving the key operation signal, the control unit 10 displays a recording menu screen 20 on the screen of the monitor 8.

FIG. 5 shows an example of the recording menu screen 20. On the recording menu screen 20, in addition to the normal recording 20a and the recording reservation 20b, a series recording reservation 20c which is a recording reservation of a series of programs broadcasted at regular intervals such as daily or weekly is also selected. I can do it.

Here, the user selects a series recording reservation 20c from the recording menu screen 20 displayed on the monitor 8 (specifically, operating the movement keys 13b1 to 13b4 to move the cursor to the series recording reservation 20c). When the control unit 10 is moved to 20c and the enter key 13b5 is operated here), the control unit 10 starts processing corresponding to the selected series recording reservation. Various methods of series recording reservation have been conventionally proposed. For example, Japanese Patent Application Laid-Open No. Hei 10-336533 discloses a method of recording a series by focusing on the fact that the names of programs in a series are the same. A method of making a reservation is disclosed. Also in the present embodiment, a series recording reservation is made using the program name as a key.

That is, when a series recording reservation is selected (when it is determined “Yes” in step S 1), the control unit 10 stores in the second memory unit 14 whether or not the series recording reservation has been made for the first time. Confirmation is made by referring to the series information (step S2). That is, in the present embodiment, it is determined whether or not the program name of the series is stored in the second memory unit 14.

As a result, when the series recording reservation is made for the first time (when it is determined as Yes in step S2), a new series number 3 and a series name are added to the program name D which is the video data reserved for series recording. Of the first broadcast (the first episode) of the video data (step S3, step S4), and the provided series number and the series serial number New series information associated with the table of contents information (program name D and address 0300 indicating the recording position of the UTOC area of HDD 5) is created and stored in second memory unit 14. As a result, new series information (program name D, series number 3, series serial number 1, and UTOC area address 0300) is additionally stored in the second memory unit 14, as shown in FIG. 2B. (Step S5).

On the other hand, as a result of the confirmation in step S 2, if it is the series information (for example, program name A) already stored in the second memory unit 14, the series number 1 included in the series information Is extracted (step S6), a new series number 4 is added to the largest series number 3 in the series number 1 (step S7), and the table of contents information (program name) of the video data is created. A new series information associated with A and the address 0400 indicating the recording position of the UTOC area of the HDD 5 is created and stored in the second memory unit 14. As a result, as shown in FIG. 2C, new series information (program name A, series number 1, series serial number 4, and UTOC area address 0400) is additionally stored in the second memory unit 14. (Step S8).

The above processing operation is a storage processing operation of series information at the time of series recording reservation, and the method of series recording reservation itself is not specifically described. For example, Japanese Patent Application Laid-Open No. H10-336533 described above. The technique described in the gazette can be applied to the present embodiment. In addition to this, for example, it is also possible to use the method described in Japanese Patent Application Laid-Open No. 2001-266457 described in the related art. The feature of the present invention is that the series recording reservation is made and the series information is created and managed in the video data recorded on the HDD 5 instead of the series recording reservation method itself.

As described above, according to the video recording / reproducing apparatus of the present invention, at the time of recording reservation, only by selecting the series recording reservation, the control unit 10 associates the series number, the series serial number, and the table of contents information. The series information is created and stored in the second memory unit 14. Thus, series programs can be collectively managed using the series information stored in the second memory unit 14.

(2) A reproduction processing operation when reproducing video data recorded in a series will be described.

When the user operates the selection key 13 a of the remote controller 13, the key operation signal is received by the key receiving unit 12 and input to the control unit 10. When receiving the key operation signal, the control unit 10 displays a selection screen (not shown) for selecting either recording or reproduction on the screen of the monitor 8.

The user operates the move keys 13b1 to 13b4 while watching the selection screen to move the cursor on the screen to the position described as “play”, and operates the enter key 13b5. This key operation signal is received by the key receiving unit 12 and input to the control unit 10. When receiving the key operation signal, the control unit 10 displays a reproduction menu screen 30 on the screen of the monitor 8.

FIG. 6 shows an example of the playback menu screen 30. On the reproduction menu screen 30, one of the normal reproduction 30a and the series reproduction 30b can be selected.

Here, the user selects the series reproduction 30 b from the reproduction menu screen 30 displayed on the monitor 8 (specifically, the cursor is moved to the series reproduction 30 b by operating the movement keys 13 b 1 to 13 b 4). Then, here, the enter key 13b5 is operated). Then, the control unit 10 starts processing corresponding to the selected series reproduction.

That is, when the series reproduction is selected, the control unit 10 reads out and displays the series information stored in the second memory unit 14. FIG. 7 shows a display example 40 of this series information.

That is, a program name, a series number, a series serial number, and a title name (title of each story) are displayed for each series number. However, the display form is not limited to this example.

When the user wants to view all of the series from the beginning, the user selects only the series number desired to be reproduced from the displayed series information. That is, operating the move keys 13b1 to 13b4 to move the cursor to, for example, the series number 1 (or the program name A), and operating the enter key 13b5 here, the control unit 10 causes the selected series number 1 (Or the program name A), based on the address information (stored in the second memory unit 14) indicating the recording position of the UTOC area associated with the serial numbers 1, 2, and 3 included in the program. The video data of the corresponding series number is read out and played back in ascending order of the serial number.

When a desired series serial number is selected from the displayed series information, the control unit 10 sets the address information indicating the recording position of the UTOC area associated with the selected series serial number. (Stored in the second memory unit 14), and reproduces only the video data of the corresponding serial number from the HDD 5.

As described above, according to the video recording / reproducing apparatus of the present invention, the series program is managed by the series information including the series number, the series serial number, and the table of contents, and the series information is stored in the UTOC of the HDD 5. Since the information is stored and managed in the second memory unit 14 instead of being written in the area, the management of the series program can be performed extremely easily. Also, when searching for a file of recorded video data, the series makes it easy to view and search easily.

[Effect of the invention]
