Abstract
Digital data is decoded from media signals (e.g., audio, images, video, etc.) using a distributed processing in which a first device receives and pre-processes the signal, and transmits it to a remote device for further decoding. One method pre-filters the media signal, leaving a residual from which digital data is decoded. Other arrangements progressively send portions of the signal for decoding operations.
