Transport stream multiplexing apparatus capable of accommodating plurality of streams
 This invention is directed to a TS(Transport Stream) multiplexing apparatus capable of accommodating plurality of PES(Packetized Elementary Stream). The present invention provides a transport stream multiplexing apparatus which is capable of multiplexing in only one transport stream multiplexing apparatus plurality of PES streams transmitted from the respective encoders by simplifying an interface between the encoders and the transport stream multiplexing apparatus by means of a PCI bus. A transport stream multiplexing apparatus of the present invention comprises a PCI interface processor for transmitting distinctly plurality of stream transmitted through a PCI bus; control signal processor for outputting a selection signal, an input signal and a transmission control signal; media buffer for outputing a transport stream packet and a transport stream payload; timing processor for outputting a timing signal required for outputting a packet; multiplexing controller for outputting a transport stream header output signal; header processing means for outputting header data in response to the transport stream header output signal; and multiplexor for multiplexing the transport stream packet and the transport stream payload input from the media buffer and outputting the transport stream packet.
