Patent ID: 7602819

Claim:
A demultiplexing device comprising: at least one merging unit receives at least two transport streams wherein when said at least two transport streams are composed of packets using the same packet identifiers for packets; said at least one merging unit produces one merged stream comprising a merged arrangement of the packets from said received at least two transport streams; said at least one merging unit additionally comprising a means for marking each of said packets in said merged stream with an identifier and to assign to said identifier a value corresponding to each received transport streams; and at least one demultiplexer corresponding to said at least one merging unit where each of said demultiplexers is capable of receiving and demultiplexing the merged stream produced by the at least one merging unit corresponding to said demultiplexer said demultiplexer being able to filter said identifiers as to determine from said identifiers the received transport stream from which the corresponding packet originates from.
