In addition, a start signal and a headline /
TV news is broadcast from a broadcasting station by adding articles and text data, the receiver determines the start of the news, digitizes and compresses and records the news, creates a table of contents for the headline, and looks at the news headline. There is a proposal for calling a desired image (Japanese Patent Laid-Open No.
-125986).

[0004] Further, the viewing state (recording time zone) of the viewer is learned, and the actually watched TV program is held as a recording candidate in a recording plan table. There is also a proposal for recording a video (Japanese Patent Laid-Open No. 2000-23074).

[0005]

However, according to the conventional proposal, information about a program is broadcasted from a broadcasting station, and a program to be recorded is selected from the information, or learning time to be watched by a viewer is learned to select a recording candidate. It is decided to record, and it is not possible to select and record a program from the content that the user wants to record.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and has as its object to capture broadcast schedule data, search for broadcast schedule data and recording information by keywords, and enable recording / reproduction.

Embodiments of the present invention will be described below. FIG. 1 is a conceptual diagram illustrating a schematic configuration of a recording / reproducing apparatus according to the present invention. The recording / reproducing device of the present invention
Receiving device, video recording unit, storage device, playback device, monitor,
Consists of a control device. A plurality of receivers 1a, 1b... For receiving broadcast waves such as television broadcasts and satellite broadcasts;
The signals received by a, 2b,... are recorded by the video recording unit 3 controlled by the CPU 6, compressed, and recorded on a single or multiple large-capacity hard disk HDDs 7. The video recording unit 3 has a configuration capable of recording broadcasts of several channels simultaneously. The CPU 6 digitizes signals (video and audio), compresses the data by a method such as MPEG2, and records the data on the HDD 7. At this time, additional information (program name, cast, broadcast time, etc.) is also recorded at the same time. C
PU6 reads the program recorded in ROM8,
The video recording unit 3 using the RAM 9 as a work area,
The HDD 7 and the video playback unit 4 are controlled to perform data compression and decompression processing to control recording and playback. Input device 10
Is means for operating a recording / reproducing device such as a keyboard, a mouse, a touch panel, and a remote controller, and for inputting an operation. The recording medium I / F 11 is an interface for transferring data of the HDD 7 to another medium such as a portable terminal to make it usable, and for taking in information such as a broadcast schedule from a recording medium such as an FD, MD, or CD. Other I / F
Reference numeral 11 denotes an interface for taking in data such as a broadcast schedule from a computer, the Internet, a LAN, and the like, and an interface for distributing a signal stored in a hard disk to a computer device having another equivalent reproduction processing function. .

As shown in FIG. 2, for example, the data to be broadcast includes a program name, cast, broadcast time, broadcast contents, etc. for each channel for each time. Infrared communication from a remote control or broadcast recording device Communication with computer devices Telephone line LAN Internet Home game machine Recording media FD, MD, CD, means for recording information (bar code, etc.) from magazines Input device 10, recording media I /
F11 and other data are fetched from the I / F 12 and stored in the HDD 7.

FIG. 3 shows an example of keywords registered when a recorded program is selected. The keywords include, for example, program names such as titles, movie titles, song titles, etc., names of actors such as actors, singers, and talents, and broadcast contents such as tennis, golf, baseball, and soccer. Register from Alternatively, an index or a keyword may be searched, edited, and registered from a database fetched from the recording medium I / F 11 or another I / F 12. For example, the keyword "diet" is searched, and "lower house", "lower house", "relay", "parliament building", and the like are edited and registered. Further, data may be registered from data such as a computer encyclopedia.

Next, a recording and reproducing method will be described. As described above, video and audio are recorded on the HDD 7 by data compressed by a method such as MPEG2. In this case, if the capacity of the HDD 7 is increased so that, for example, a broadcast of several channels can be stored for about one week, it is possible to select and reproduce all of the next week and the previous week. Such usage forms are possible. As a method of selecting a program, a program may be selected for a preset time from the broadcast schedule data shown in FIG. 2, but as shown in FIG.
It is also possible to select a keyword by using the keyword shown in (1), search the broadcast schedule data by referring to the database by the CPU 6, and if there is a program including the keyword, record the program. When there are several types of selected keywords and there are more videos to be recorded, all the images including the keywords may be recorded, or only the keywords may be recorded by prioritizing the broadcast time or the like.

In the reproduction method, a keyword is selected, and as shown in FIG. 5, the CPU 6 searches for and reproduces the broadcast schedule data or additional information taken in at the time of recording by referring to a database. Since the recorded contents are digital recordings, cue reproduction, skip reproduction, and the like are possible, and the reproduction order can be registered and reproduced by oneself.
In addition, since there is a recording index, retrieval during reproduction is easy.

The present invention is not limited to the above embodiment, but can be variously modified. For example, we currently use text characters as a means of searching,
In addition to this, it is also possible to select and record a video from the audio being broadcast by detecting the voiceprint of the audio or performing audio recognition. Alternatively, a broadcast schedule may be input from a broadcast wave. In the present invention, a video may be acquired from a video camera or a scanner, and a broadcast schedule may be input by character recognition.

[0014]

As described above, according to the present invention, a large number of video input means are provided to record broadcast contents as digital information in a large-capacity storage device by data compression and to record a broadcast schedule on a computer, the Internet, , As a database, and searching / recording / reproducing this database based on keywords, it is possible to selectively record and reproduce a large amount of broadcast programs,
By increasing the recorded contents, a usage form like a home broadcast station becomes possible.
