The present invention relates to a recording information processing apparatus for a television having a satellite broadcasting receiving function for automatically decoding and processing VCR recording information so that it can be usefully applied to recording satellite broadcasting programs.

In general, according to a television for reproducing a broadcast program transmitted by a plurality of broadcasting stations, a channel of a VHF / UHF band uniquely allocated to each broadcasting station is tuned to reproduce video and audio of a broadcast program organized by a corresponding broadcasting station. Will work.

In such a television, when a video tape recorder (VCR) for recording and reproducing a broadcast program is usually connected through a video / audio cable, video and audio signals are reproduced from the video tape by the video tape recorder. The television also acts as a video and audio output device of the broadcast program recorded in the VCR.

However, in the case of transmitting a broadcast program through a channel assigned by the VHF / UHF band, the astigmatism situation of the broadcast program occurs depending on the region, which makes it impossible to receive high-quality and high-quality broadcast programs, as well as a large number of extensions. The allocation of channels to broadcast stations is accompanied by limitations, so that the multi-channelization required by the increase of broadcast stations is inevitably limited.

Therefore, in recent years, a satellite broadcasting system using satellite media has been put into practical use, so that multi-channelization and a high-quality broadcasting program can be viewed in an astigmatism zone accompanied by an increase in broadcasting stations.
