<p>A coded data decoding device provided with a circuit which successively receives a series of coded data frames containing a plurality of multiplexed band data divided into a plurality of prescribed frequency bands, each multiplexed band data including coded information data in the corresponding frequency band and processing data used for coding the information data, and processes each coded data frame so as to separate the coded information data and processing data from each other, circuit means which decodes the coded information data of each frequency band by using the processing data separated from the information data, and either means which decides whether or not each data frame must be decoded based on the level of the coded information data in at least one band selected from among the frequency bands contained in the data frames, or another means which selects frames to be processed so as to only decode frames selected from among the data frames.</p> |
