Abstract:
A bi-phase decoder (296-1) suitable for use in a broadcast router (100) and an associated method for extracting subframes of digital audio data from a stream of digital audio data. Logical circuitry (298) within the bi-phase decoder (296) extracts subframes of the digital audio data by constructing a transition window from an estimated bit time, sampling the stream of digital audio data using a fast clock and applying the sampled stream of digital audio data to the transition window to identify transitions indicative of preambles of the subframes of digital audio data.
