Abstract:
1. A signal processing apparatus for processing data streams that comprises headers and signal data interspersed with each other, each header specifying a distance to a subsequent header, each header corresponding to a frame of signal data, the header being associated with a pointer that points to a starting point of the signal data for that frame relative to the header, the apparatus comprising an input for receiving an original data stream; a stream converter following the input, the stream converter converting the original data stream into an intermediate data stream, the stream converter moving the starting points of the frames to predetermined positions and modifying the headers to create additional space between the headers so that the frames fit between headers; wherein the stream converter is arranged to modify the headers by adjusting a bit rate specified in the headers of the intermediate stream without modifying an actual bit rate of the signal data.
