Abstract:
A transport stream (TS) multiplexing apparatus, comprising:matching means for receiving data signals and control signals for an external source and distinctly outputting said control signals as an address signal and a read/write signals and outputting said data signals;control signal processing means for receiving said address signal and said read/write signal and outputting a selection signal, an input signal, and a transmission control signal;buffering means for receiving said data signals, said selection signal, and said input signal, storing said data signals in response to said selection signal and said input signal, and outputting an output request signal;timing processing means for receiving a reset signal and a clock signal from an external source and generating a timing signal and a program clock reference (PCR) data in response to said reset signal and said clock signal;multiplexing control means for receiving said output request signal, said clock signal, said reset signal and a set signal from said external source, and said timing signal, processing said output request according to an output schedule, and outputting a payload output signal, a retransmission signal and a TS header output signal;said buffering means further comprising means for receiving said payload output signal and said retransmission signal and outputting a TS packet and a TS payload in response to said payload output signal and said retransmission signal;header processing means for receiving said transmission control signal, said TS header output signal, said PCR data and said data signal, processing said data signals and PCR data in response to said transmission control signal and outputting a TS header data in response to said TS header output signal; andpacket multiplexing means for receiving and multiplexing said TS header data, said TS packet and said TS payload and outputting said TS packet.
