Abstract
A data multiplexer and a method thereof for multiplexing audio data, video data and additional data for digital television broadcasting. Size information for such data may be obtained and supplied by way of a CPU bus to a CPU which utilizes such size information in controlling a multiplexing operation. The audio, video and additional data may be multiplexed under the control of the CPU without being supplied to the CPU. As a result, high speed multiplexing may be performed.
