MULTIPLEX SEPARATION PROCESSOR

摘要

PROBLEM TO BE SOLVED: To provide a multiplex separation processor which can reduce power consumption due to wasteful operations during waiting of a TS packet input and the processing of the TS packet. SOLUTION: System clock control pats 21 to 24 for controlling the supply of a system clock to a function block by a microcode instruction are arranged in respective function blocks of a descrambler 201, a filter 202, an output interface 203 and a TS packet 209. The function blocks become operative when the system clock is supplied, and become inoperative, when the supply of the system block is stopped.
