Abstract
When TV images are inputted as video data through a channel selected by the first inputting means, the video information including audio information is compressively encoded at a specified compression coding ratio by a compression coding portion, provided with a compression coding ratio statement attached thereto by the compression definition data adding portion and recorded on a recording portion at the specified compression ratio specified by the compression coding control portion. An electronic program guide overlaid on TV signal, which includes genre information, is input to a second information inputting means, decoded by a second information decoding portion and stored as data. The compression coding ratio is set in a setting table with reference to the data by a compression coding ratio control portion.
