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： 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： Disclosed is a device for filtering out a null packet in a data stream for example an MPEG-2 TS (Transport Stream) to avoid bandwidth waste when it is transmitted to a backbone network. The device includes a plurality of receiving interfaces, a filter unit, and a controller. The receiving interfaces receive parallel data, such as DVB-ASI (Digital Video Broadcasting-Asynchronous Serial Interface) inputs as channel-by-channel MPEG-2 data. The filter unit counts the respective numbers of data packets and non-data packets of the data input from the receiving interfaces and filters a null packet in the data. A network transmission unit transmits the filtered data to a backbone network. The controller calculates a bit rate based on both of the count numbers received from the filter unit.
