摘要： In an MPEG-2 decoding system, a transport decoder decodes a transport packet corresponding to a PID from an input transport stream, and retrieves a PAT/PMT from the stream when it is requested to retrieve PSI. A pre-decoder checks PSI stored in a PSI memory if a request to change to a desired channel is made, reads PIDs of transport packets for a PES of a program corresponding to the desired channel from the PSI memory to provide it to the transport decoder, receives the PAT/PMT from therefrom at a predetermined time, and updates the contents of the memory using the PAT/PMT. When a transport stream is decoded, PSI is previously extracted therefrom and stored in the memory. Upon the channel change request, PIDs of transport packets for the PES of the desired program are obtained referring to the stored PSI, and transport packets having the PIDs are retrieved and decoded.

摘要： A broadcast/communication convergence system and method for transmitting and receiving Ethernet data by an optical network unit (ONU) performing a time division multiplexing (TDM) operation and switching by a network switch. A resultant signal is transmitted to a corresponding subscriber set-top box (SSTB), and data from the SSTB is provided to the network switch. A length of an Ethernet data frame is provided from the network switch, and an encapsulation generates and inserts data length information into an Ethernet data frame, for transmission to the SSTB. The SSTB carries out a TDM operation for a signal transmitted from the ONU, and separates the signal into Ethernet and broadcast data. A framing bit is detected based on a result of the separated signals, the length information is detected. A preamble bit and a start-of-field delimiter (SFD) are inserted into the recognized Ethernet data to recover the original Ethernet data.
