  2. Description of the Related Art In recent years, there has been provided a recording device that can store a large number of program contents by using a large-capacity HDD (hard disk drive) or the like, such as an HDD recorder. With such a recording device, server-type broadcasting in which received program content is once stored in the HDD and then played back is realized. In this server-type broadcast, program content and detailed additional information related thereto are stored in a large-capacity storage device such as an HDD, so that the stored program content can be viewed from a predesignated time, or additional information is stored. It is possible to search for scenes and view digests by using them.

  When recording recorded program content on such a recording device capable of supporting server-type broadcasting, information such as a title and thumbnail indicating the program content is displayed on the screen, and the desired program content can be viewed on this screen. In general, a technology related to ECG (Electronic Content Guide) useful for presenting information related to recorded program content to the viewer is disclosed (Patent Documents 1 to 3). ).

Conventionally, for example, as shown in FIG. 9, a list is displayed from the top in the new order based on the date and time when the program content was recorded, and information related to the program content is provided to the viewer. In particular, for the program content 93a selected by the cursor, the detailed information is displayed in the separate frame 92.

  As described above, with the recent increase in capacity of storage media, the number of program contents that can be stored in a recording device has become very large, for example, exceeding 500. In addition, when server type broadcasting becomes widespread, the transmission path through which program content is provided is not limited to broadcast radio waves such as conventional terrestrial digital broadcasting, BS broadcasting, CS broadcasting, etc., and Internet communication may be used. Therefore, the program content provided to the viewer is expected to increase further.

  In this way, when a large number of recorded program contents are displayed, if information on the program contents is displayed as a list in order of recording date and time as shown in FIG. 9, this list display cannot be accommodated on one screen, and tens of pages or Can be close to a hundred pages. Therefore, when a very large number of program contents are stored in the recording device, searching for the desired program contents itself becomes a complicated operation.

  An object of the present invention is to provide a recorded program management apparatus capable of efficiently searching for a desired program content even when a large number of program contents are stored in a recording device such as an HDD recorder.

In order to achieve the above object, the present invention is a recorded program management apparatus comprising display control means for displaying a recorded program to be viewed in a selectable state based on program information of recorded program content,
The program information includes broadcast station information indicating a broadcast station providing program content,
The display control means is adapted to record the recorded program for each affiliated station (NHK General / Education series, Nippon Television Network series, Tokyo Broadcast series, Fuji Television series, TV Asahi series, TV Tokyo series, Etc.), and a list display according to affiliated stations in which the recorded programs having the same grouped affiliated station information are extracted from the recorded programs and the information of the program is displayed in a plurality of list frames. A screen can be generated . As a result, a list display based on affiliated station information can be used as a method for narrowing down the desired program content from the recorded program content.

  The program information includes network information indicating a transmission path (terrestrial digital broadcast, BS broadcast, CS broadcast, etc.) used to provide program content,
  The display control means can extract a recorded program having the same network information from the recorded programs, and can generate a list display screen for each network in which information of the recorded program is displayed in a plurality of list frames. Is. As a result, the recorded programs can be grouped by a transmission path through which the program content is provided, that is, so-called network classification, and information related to the recorded programs can be displayed as a list.

  Furthermore, the display control means extracts a recorded program with the same broadcasting station information from the recorded programs, and displays a list display screen for each broadcasting station that displays information of the recorded programs in a plurality of list frames. It can be generated. As a result, program contents can be grouped not only in the network segment but also in the broadcast station segment, and information related to the recorded program can be displayed in a list.

  Further, the display control means displays on the network-specific list display screen when a predetermined operation (for example, operation of a broadcast station classification button on the remote controller) is performed by the input device on the network-specific list display screen. A recorded program having the same broadcast station information is extracted from the recorded programs, and the broadcast station list display screen is generated. Thereby, since the recorded programs grouped by the network section are further grouped by the broadcasting station section, the desired program content can be further narrowed down and displayed in a list.

  According to the present invention, in a recording device such as an HDD recorder, the recorded program content is grouped by network category, broadcast station category, or affiliated station category, and the program content corresponding to the category desired by the viewer is narrowed down. Even if a large number of recorded programs are stored and information related to program contents is displayed in a list in the order of recording date and time, the viewer may be displayed in a list. However, there is an effect that a desired program content can be efficiently narrowed down and searched. In particular, it is useful when applied to an ECG compatible with server type broadcasting.
