Abstract:
A data processing device for processing a stream of data, comprising:means for decoding the stream of data to form a stream of decompressed audio data;a first memory circuit operable to hold at least a first frame of the stream of decompressed audio data, the first frame of data having a predetermined number of decompressed audio data words, the memory circuit connected to an address bus and to a data bus;a port for transferring the stream of decompressed audio data to another device;means for determining a first presentation time for the frame of decompressed audio data;means for determining a first reference time;a processing unit connected to the first memory circuit and to the port; the processing unit operable to transfer the first frame of decompressed audio data to the port, the processing unit being further operable to determine a first time difference between the first presentation time and the first reference time; andmeans for transferring only a first portion of the first frame in accordance with the first time difference, wherein the first portion of the first frame is a number of decompressed audio data words selected from a range consisting of any whole number between and including 1 and the predetermined number of data words, whereby synchronism between a second presentation time of a second frame of data and a second reference time is improved.
