Multiplexing and DEMULTIPLEXING DEVICE AND PROCESS FOR AT LEAST TWO TRANSPORT STREAMS using MPEG transport priority bit

The invention relates to dmux at least two transmitting stream (21-22) dmux device (1) and processing method. The dmux device comprises: At least one of unit (2), for receiving at least two transmission streams, and generating a comprises a group (P1, P2 sequencing) is merging primitively the merged stream (23). The merged unit comprises a groups of mark the identification code to each mark device (4), wherein the identification code to methods of each and a given value of stream transmission. A device dmux - comprising at least dmux (3), a conductive connection part corresponding to the merged provided with a device for generating dmux, and dmuxes to a. The dmux filter identification code, and determining from from obtaining corresponding packet transmitting stream for receiving. A applied in digital television receiver.
