Data stream output method for MPEG decoder of digital TV receiver, involves changing frequency of clock signal used for reading-out data from FIFO memory, based on its storage level

摘要

Data stream output from an audio decoder (1) is stored in a FIFO memory (2). The data storage level of the memory is monitored, based on which a controller (3) changes the frequency of clock signal used for reading-out data from the memory. An Independent claim is also included for data stream output device.
