DATA MULTIPLEXER AND ITS METHOD

摘要

PROBLEM TO BE SOLVED: To provide a data multiplexer and its method where a signal not used by a receiver side is not produced by recognizing a bit rate of an input signal and setting dynamically an output bit rate from the input bit rate. SOLUTION: A header analysis section 22 analyzes headers of three PES streams to read input bit rate information. A bit rate calculation section 34 calculates an output bit rate from the bit rate information or the like analyzed by the header analysis section 22. A data output control section 36 controls a bit rate of a bit stream outputted from a multiplex register 31 to an output buffer 37 according to the bit rate calculated by the bit rate calculation section 34.
