DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a broadcast receiving / recording / reproducing apparatus for receiving a television broadcast or the like and recording / reproducing the broadcast contents.

[0002]

2. Description of the Related Art Currently, a home video tape recorder (VT) is a typical broadcast receiving / recording / reproducing apparatus for receiving a television broadcast or the like and recording / reproducing the broadcast content.
R) is used. In this VTR, in addition to a normal recording mode in which recording is started by pressing a recording button, a program of a channel is automatically recorded by presetting a broadcast channel, recording start and end times, and the like. There is a reserved recording mode, in which a program on a preset channel can be automatically recorded even when the user is absent or watching a program on another channel on the television receiver. There is also a proposal to superimpose a control signal on a video signal of a program, broadcast the control signal, and use the control signal to simplify the setting of a reservation recording mode.

Further, in the current television broadcasting, a text multiplex broadcasting in which text information and the like are multiplexed and transmitted during a blanking period of a video signal and the text information is reproduced by a television receiver is practically used. Has been
Furthermore, the signal is inserted during the blanking period of the video signal, the characteristics of the broadcasted video signal are measured, and the characteristics of the television receiver are automatically adjusted to match the characteristics of the video signal that has deteriorated during air transmission. Some are trying to adjust. However, even when recording is performed in a reserved recording mode in which a control signal is superimposed on a video signal of the above-described program and used, the VTR
Only the program information is recorded on the tape by the user. To reproduce the information, the user can determine where on the tape the program information is recorded by another method as in the case of normal recording. It had to be recorded.

[0004]

When a plurality of pieces of program information are recorded on one tape by a VTR, operations such as fast-forwarding and rewinding the tape are required to reproduce specific program information. It took a long time to start playback. Further, since only the program information is recorded, there is a drawback that it is not possible to later determine which program is recorded in which part or what the recorded program information is.

[0005] The applicant of the present invention compresses and records program information on a disk recording device, records additional information broadcast together with the program information, displays the additional information, and selectively reproduces the program information. A recording and playback system was proposed. However, since a disk-shaped recording medium has a smaller recording capacity than a tape-shaped recording medium, in order to record a large amount of program information, it is necessary to increase the compression ratio or use a disk recording device having a large recording capacity. I had to. When the compression ratio is increased, the image quality inevitably deteriorates, and a disk recording device having a large storage capacity is expensive.

Therefore, the present invention selectively uses, for example, a first recording device having fast access and a second recording device having a large storage capacity depending on program information to be recorded, and selects a title indicating the displayed program information. It is an object of the present invention to solve the above-mentioned problem by providing a broadcast receiving / recording / reproducing apparatus capable of immediately reproducing program information without being aware of which recording apparatus is recorded by simply performing the operation. .
