no. 1 Embodiment

[0025] Fig. 1 is a schematic block diagram of the first embodiment of the present invention. After the user selects a desired channel using the remote controller 5 as a pointing device, the remote controller 5 transmits an infrared signal representing the designated channel number information from an infrared light emitting device (not shown) to the light receiving unit 6. The light receiving unit 6 analyzes the received infrared signal, determines which button (not shown in the figure) of the remote control 5 has been pressed, and notifies the system control unit 7. The system control unit 7 sets the setting (receiving frequency and PID (PacketIdentification) information) corresponding to the indicated channel (the packet identifier corresponding to the audio data and video data of the desired program in the multiplexed transport data stream )) Notify the tuner 1 and the demultiplexer 3. The tuner 1, the demodulation unit 2, and the signal separator 3 constituting the input unit ...

no. 2 Embodiment

[0041] In the first embodiment, the data number 401, the type 402, the stored program counter 403, and the stored program information 404 are written at the head of the video tape 400. In this method, every time a program is saved, the video tape must be rewound, which is inconvenient. In accordance with a predetermined interval (for example, a data interval equivalent to 1 minute) existing in the video tape, only the data number is written in a blank area outside the video and audio recording area (601 in FIG. 10). The remaining information is stored in the flash ROM 13 according to the data structure shown in FIG. 11. In FIG. 11, 700 is the information database of the video tape stored in the flash ROM 13. 701 is a tape counter for setting the number of registered tapes. 702 is a video tape information record that stores each video tape information, and only a number as large as the value of the tape counter 701 is effective. The videotape information record 702 is composed of a...

Abstract

A designated program is recorded in a hard disk by a hard disk controller (11) according to a program reservation database. A unique number is indicated at the head block of a video cassette tape for identifying the tape, and a genre of programs is recorded in the subsequent block of the tape. When the video cassette tape is loaded, the information concerning the genre is read, and if there is record information of the same genre as that of the tape contained in the hard disk, it is additionally recorded in the video cassette tape.

Description

Technical field [0001] The present invention relates to a recording and reproducing device and a recording and reproducing control method, and more specifically, to a recording and reproducing device and a recording and reproducing control method suitable for recording and reproducing of digital television broadcasting. Background technique [0002] The STB (set-top box) that receives digital TV broadcasts, although its main responsibility is to output the received digital video and audio data in analog mode, in order to record the received digital video and audio data, it is proposed to install a hard disk device in the STB As the structure of digital recording media. [0003] In digital television broadcasting, a service that uses transport stream packets to transmit broadcast program information, which is applied in an electronic program guide (EPG), etc., is also performed. [0004] JP 2000-285576 discloses a broadcast information recording device that compares user preferenc...
