ABSTRACT:
A multiplexing system which detects multiplexing errors, includes PES packetizing modules that packetize elementary streams (ES) to produce packetized elementary streams (PES), and a TS/PS packetizing module that multiplexes packetized elementary streams (PES) to produce transport streams (TS) or program streams (PS). Comparators are provided each to compare a non-packetized elementary stream (ES) or a packetized elementary stream (PES) stored in a FIFO memory with the packetized elementary stream (ES) or packetized elementary stream (PES) from the packetizing modules. Based on the comparison result, a control module detects errors in the packetizing modules.
