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.

The apparatus includes an encoder for encoding and outputting the video data as a compressed bit stream, a channel error measurement unit for measuring Signal-to-Noise Ratio (SNR) or Carrier-to-Noise Ratio (CNR) of a wireless channel, and an encoder optimization module for determining if the current fading is slow fading or fast fading. A control signal is output to reduce a frame transmission ratio or to change the quality of the vide data if it is determined that the current fading is slow fading. Another control signal is output to adjust the size of a data output buffer of the wireless channel if it is determined that the current fading is fast fading. The apparatus also includes a temporal Scalable Video Coding (SVC) selector 24 and an SNR SVC selector 22 for selecting the frame transmission ratio or the bit rate according to the control signal output from the encoder optimization module, to provide a frame selection signal or a bit rate selection signal to the encoder.
