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.

摘要： A photoelectric cross-connect system for an optical-communication system minimizes service recovery time when an error is generated. A plurality of nodes are connected by an optical-transmission line wherein each nodes automatically recognizes a data rate of an input signal and communicates over a redundant channel with an adjacent node when there is a certain type of error. An optical-receiving unit receives an optical signal performs O/E conversion. A main optical-transmitting unit recovers clock and data signals according to the converted signal and sets a data rate according to the converted signal for subsequent transmission; a redundant optical-transmitting unit recovers a clock and data according to the converted signal and sets a data rate according to the converted signal for subsequent transmission A switch provides selectively connection state between the optical-receiving unit and the main optical-transmitting unit and between the optical-receiving unit and the redundant optical-transmitting unit.

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.
