Zusammenfassung:The present invention discloses a method and a device for demultiplexing of a multi-program transmission stream. The method comprises the steps of: analyzing a first program association table in a received TS (Transport Stream) data packet; analyzing the first program association table to obtain the total number of programs and identification information corresponding to a program mapping table recording each program; searching a TS packet of a program mapping table of each program according to the identification information to obtain the program mapping table of each program; according to theprogram mapping table of each program, determining a voice frequency packet and a video packet of each set of program; performing division for the first program association table to generate a plurality of second program association tables, wherein each second program association table corresponds to one set of program; and repacking the second program association table, the program mapping table, the voice frequency pac
