Abstract
A digital signal multiplexing method and apparatus in which plural degree-one multiplexed streams produced on time-divisionally multiplexing a bitstream of one or more digital signals are received and are time-divisionally multiplexed to generate a degree two multiplexed stream. Specifically, plural degree-one multiplexed streams are received, and the received degree-one multiplexed streams are time-divisionally multiplexed based on a repetitive pattern associated with the bitrate of the respective degree-one multiplexed streams to generate a degree two multiplexed stream. The time reference value attached to the degree two multiplexed stream is corrected based on the reference clocks not synchronized with the system clocks of the degree-one multiplexed streams. A pre-set volume of the dummy data is multiplexed if the corrected time reference value becomes larger than the time reference value attached to the degree-one multiplexed streams.
