Description

  The present invention relates to an apparatus capable of receiving and recording video and audio, and more particularly to an apparatus including a recording device such as a television and a recorder, and operation buttons such as a remote controller.

  Video and audio data handled by various devices such as personal computers, AV devices, and information home appliances are digitized. In these devices, when receiving and playing a broadcast program, recorded content, or content distributed over a network such as the Internet, the user switches programs (channels) to obtain desired information. I often watch while doing.

  In the conventional broadcast receiving / recording / reproducing apparatus, there is a technique or apparatus for generating a display list along a time axis for a program that a user wants to view by setting a category or the like, as in the following documents.

JP 2001-333358 A

  In the above prior art, the user has to set information necessary for searching in order to generate a program list to be viewed. However, the user finds an actor who does not know the name of interest when he / she wants to continuously watch information such as a special news while watching a program such as news, or when he / she happens to watch a drama, In some cases, you may want to know the program that will appear. In such a case, it is troublesome to open the setting screen and set necessary information, which is not convenient.

  The above problem can be solved by the configuration described in the claims as an example.

  According to the present invention, it is possible to provide a broadcast receiving / recording / reproducing apparatus that realizes a function of continuously viewing a program desired by a user.

  Examples of the present invention will be described below.

  First, FIG. 1 is a block diagram showing a connection between a broadcast receiving / recording / reproducing apparatus as an embodiment to which the present invention is applied and a network. In FIG. 1, 100 is a recorder, 101 is an external device, and 102 is a network. The system control circuit 103 has a CPU and a memory and controls the entire system. Although not shown, the system control circuit 103 generally processes input information when the user operates a button or the like. The demodulation circuit 112 demodulates the video / audio information received by the antenna 113, acquires the video / audio data, and passes the data to the CODEC (COmpression / DECompression) circuit 105. The CODEC circuit 105 extracts the stream data of the content (for example, in the current digital broadcasting, since a plurality of program data are scattered and transmitted as one stream, information on the program to be recorded is extracted on the receiving side. Although not described to simplify the configuration diagram, the above extraction circuit may be a separate circuit from the CODEC circuit.) MPEG (Moving Picture Experts Group) or JPEG (Joint Photographic coding Experts Group) as required Compressed video and audio information. These video / audio data and video / audio data obtained by subjecting the input signal from the external input terminal 114 to a desired signal conversion process by the external input circuit 104 are compressed by the CODEC circuit 105 and recorded as necessary. In the control circuit 106, recording is performed on an HDD (Hard Disk Drive) of the recording medium 107 or a DVD (Digital Versatile Disc) of the recording medium 115. In this embodiment, the recording medium for writing is described as being an HDD or a DVD. However, the present invention is not limited to this, and the HDD corresponding to the security function is assumed to be used for removal purposes. It can be applied to a recording medium for recording information, such as a magneto-optical disk or a semiconductor memory.

  In addition, when the video / audio information to be handled needs to be copyright-protected, an encryption / decryption key is generated by the encryption / decryption circuit 111 before being recorded in the above, and is recorded after being encrypted. .

  The video / audio information received by the antenna 113, the video / audio data at the time of recording, and the data read by the recording control circuit 106 from the recording media 107 and 109 at the time of reproduction are combined by the encryption / decryption circuit 111 as necessary. Then, the data decoded (decompressed) by the CODEC circuit 105 is output to the display device 109 by the display control circuit 108. The network control circuit 110 performs processing for acquiring the video / audio data from the network. Thereby, in order to acquire data handled by the recorder 100, it is possible to access from both a mobile phone connected to the network, a device such as a PDA, a PC, and a recorder (external device 101).

  FIG. 2 shows a list of prioritized keywords extracted from recently watched programs by the user and a viewing candidate program in which related program information is grouped in time series in a recorder according to an embodiment to which the present invention is applied. The list is shown.

  In FIG. 2, 200 indicates a keyword list, 201 indicates priority information, and the more frequently used keywords are set higher. Reference numeral 202 denotes a keyword, which is used when selecting a viewing candidate to be described later. Reference numeral 203 denotes viewing time information. A keyword extracted from a program viewed by the user for a longer time is set higher.

  210 indicates a viewing candidate list, 211 indicates media information, and indicates from which route of content transmitted by broadcast waves, recorded content, content on a network, and content on a connected external device. . 212 stores program information indicating which content on the medium designated by 211 is designated.

  FIG. 3 shows an example of a screen displayed on a recorder which is an embodiment to which the present invention is applied. This will be described in an example described later.

  Next, the operation flow at the time of updating the viewing candidate list registration in the recorder according to an embodiment to which the present invention is applied will be described with reference to FIG.

  Viewing by the user is started, and the program information being viewed is acquired in S400. For example, the system control circuit 103 demodulates the information received by the antenna 113 by the demodulation circuit 112, takes out necessary program information by the CODEC circuit 105 or the system control circuit 103, and the system control circuit 103 extracts keywords. . The system control circuit 103 performs a process of increasing the priority of the overlapping keyword in S403, and registers or updates the viewing candidate list in S404.

  When the special information mode is activated by the user, the system control circuit 103 determines this in S405, and automatically programs to be viewed based on the information in the viewing candidate list in S406 until it is invalidated thereafter. Switch. If the distribution times of the viewing candidate programs are duplicated, adjustment is made in S404 and S406 so that the back recording can be performed and played back at a free time.

  Regardless of the special information mode, the processing from S400 to S404 is repeated, and the viewing candidate list is updated to the latest information.

  As described above, it is possible to realize an easy-to-use recorder that allows a user to continuously view a program that the user wants to view at any time.
