Abstract (en)

A digital signal multiplexing apparatus is provided which can multiplex service data having a plurality of different bit rates and change the bit rate even during signal transmission. A controller generates multiplex configuration information indicating how service data is multiplexed, in accordance with instructions, and generates commands whose contents match the multiplex configuration information. The generated multiplex configuration information is written in a memory circuit, and the generated command is converted by a CPU into a control signal for encoders. The multiplex configuration information read from the memory circuit is encoded by a convolution encoder into a predetermined format. A plurality of service data sets are encoded by convolution encoders into predetermined formats in accordance with control signals converted by CPU, and multiplexed by a multiplexer circuit. The data encoded by the convolution encoder and the data multiplexed by the multiplexer circuit are further multiplexed by another multiplexer circuit.
