1. one kind is multiplexed to the multiplexer of secondary signal stream to a plurality of first signal flows, and first signal flow has same substantially first rate, and secondary signal stream has second speed that is higher than first rate, and multiplexer comprises:

  • Buffer is used for buffer memory first signal flow;

    The SRTS circuit is used to receive the SRTS value of each first signal flow;

    Local SRTS circuit is used for producing according to reference clock speed the local SRTS value of each first signal flow;

    Fill circuit, be used for filling a plurality of first signal flows according to filling command signal, this filling command signal is produced according to its SRTS value and local SRTS value sequence separately for each first signal flow;

    AndCombination device circuit is used for all first signal flows are combined into secondary signal stream.
