ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention:
This invention relates to a TS(Transport Stream) multiplexing apparatus, and more particularly, to a TS multiplexing apparatus capable of accommodating a plurality of PES(Packetized Elementary Stream) on the basis of PCI(Peripheral Compliant Interface) in which, when PES signals in MPEG(Moving Picture Expert Group)-2 video/audio system are processed in real time as one unit, plurality of MPEG-2 video/audio PES stream transmitted via a PCI bus are processed by only one TS multiplexing apparatus, and then matched with ATM network.
2. Description of the Related Art:
Conventionally, when programs are generated with PMT(Program Map Table), PAT (Program Association Table), PCR(Program Clock Reference), video packet, audio packet, etc. as the object of multimedia, plurality of PES streams transmitted from the respective encoders should be processed by the corresponding number of TS multiplexing apparatus, resulting in the need of a number of TS multiplexing apparatus. For example, as a TS multiplexing apparatus with 5 input terminals is required for one channel, plurality of TS multiplexing apparatus for accommodating per channel is needed for many channels. This leads to the inefficient use of the TS multiplexing apparatus.
SUMMARY OF THE INVENTION
For the purpose of overcoming the problem described above, the object of the present invention is to provide a transport stream multiplexing apparatus that can multiplex plurality of PES stream, transmitted from the respective encoders by means of one transport stream multiplexing apparatus by simplifying an interface between the encoders and the transport stream multiplexing apparatus by using a PCI bus.
In accordance with the aspects of the present invention, a transport stream multiplexing apparatus which transmits distinctly the data and controls the related signal input from the external; control signal processing that combines an address signal and a read/write signal inputted from that matching and outputs a selection signal, an input signal and a transmission control signal; buffering which the storing data inputted from the matching in response to the selection signal and the input signal inputted from the control signal process, outputs an output request signal, and outputting a transport stream packet and a transport stream payload in response to a payload output signal and a retransmission signal inputted according to the output request signal; timing process that the producing the timing signal required for outputting a packet in response to a reset signal and a clock signal inputted from the external, and outputs a program clock reference data; multiplexing control, that for processing according to an output scheduling the output request signal inputted from the buffering and the timing signal imputted from the timing process to output the payload output signal and the retransmission signal to the buffering process, and outputs a transport stream header output signal; header processing, which outputs header data in response to the transport stream header output signal inputted from the multiplexing control after processing data inputted from the matching and data inputted from the timing processing in response to the transmission control signal inputted from the control signal processing; and multiplexing which multiplexes the header data inputted from the header processing and the transport stream packet and the transport stream payload inputted from the buffering and outputs the transport stream packet.
