The digital signal multiplexing device also sets the sequence of time-divisional multiplexing of the packets as interleaving patterns repeated at a pre-set period. The digital signal multiplexing device time-divisionally multiplexes the degree-one multiplexed streams on the packet basis to generate a degree-two multiplexed stream.

In one implementation of the system, one or more coding parameters are extracted from the first and/or second encoded streams and one or more parameters of the first and/or second encoded streams are changed in accordance with the extracted parameter(s) in order to effectuate seamless splicing. In another implementation, the coding parameters applied to the first encoded stream are referenced when encoding the second stream such that the resulting second encoded stream can be seamlessly spliced with the first encoded stream.

Abstract: When editing an image signal and a sound signal or these signals multiplexed using a conventional digital signal editing apparatus, it is necessary to provide a reproduction apparatus for reproducing an original signal and a recording apparatus for recording the signal edited.

A storage unit 3 stores the reproduction information read out from the storage medium 1 by the read-out unit 2. A control unit 3 controls read-out of the read-out unit 2 according to the aforementioned reproduction information from the storage unit 3.
