摘要： In an MPEG-2 decoding system, a transport decoder decodes a transport packet corresponding to a Program Identification (PID) from an input transport stream, and retrieves a Program Association Table/Program Map Table PAT/PMT) from the stream when it is requested to retrieve Program Specific lnformation (PSI). A pre-decoder checks PSI stored in a PSI memory in response to a request to change to a desired channnel, reads PIDs of transport packets for a Packetized Elementary Stream (PES) of a program corresponding to the desired channel from the PSI memory to provide it to the transport decoder, receives the PAT/PMT and updates the contents of the memory using the PAT/PMT. After decoding, PSI previously extracted therefrom is stored in the memory. PIDs of transport packets for the PES of 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.

摘要： A system having a transmitter and a receiver provides sign language video data in a broadcasting-communication convergence system. A transmitter extracts data, to which a sign language is to be applied, from the multimedia data, converts the extracted data into motion data, converts the motion data into an avatar motion schema indicative of avatar motion data, converts the avatar motion schema into metadata, multiplexes the multimedia data and the metadata, and transmits the multiplexed data. A receiver receives the multiplexed data, demultiplexes the received multiplexed data, extracts an avatar motion schema using the metadata, generates sign language video data by controlling a motion of an avatar through the avatar motion schema, multiplexes the sign language video data and the multimedia data, and transmits the multiplexed data to a display unit.
