METHOD FOR TAKING OUT AND PROCESSING VIDEO DATA AND PROGRAM GUIDE, WHICH ARE TRANSMITTED BY DIFFERENT ENCODING FORMAT

摘要

PROBLEM TO BE SOLVED: To take in and process video data and program guide information, which are take out from input data encoded by a broadcasting variable encoding format.SOLUTION: An antenna 15 receives digital bit stream showing video information which is encoded by one of a plurality of different formats and transmitted by one of the plurality of transmission channels. Processors 17, 55, 20, 25, 30 and 50 identify and take out program guide information including a plurality of channel maps. The channel map associates video channel output with the transmission channel, and associates the encoding format with the transmission channel. Adaptive decoders 35, 40 and 45 decode the bit stream and supply the video channel output in response to the program guide information.
