摘要

A digital audio broadcast receiver for receiving at least two broadcast ensembles, each ensemble being made up of a plurality of transmission frames and each transmission frame including an information channel and a time interleaved main service channel. The broadcast receiver includes means for acquiring and processing during a plurality of relatively long periods a given broadcast ensemble to extract and reproduce selected audio or other service data from said main service channel. The means for acquiring and processing is also operable to process a further broadcast ensemble at least to detect the presence thereof during one or more relatively short intervals interspersed with said relatively long periods, thereby to obtain data relating to said further ensemble. <IMAGE>
