摘要： A demultiplexer for separating different format packets from a multiplexed data stream. Each packet format has a different type of header which is analyzed based on micro-codes read out in sequence from a command memory. By using micro-codes, the demultiplexer minimizes the circuitry required to process multiple formats (e.g. digital video broadcasting (DVB), digital satellite system (DSS), and digital versatile disc (DVD)). The packets are separated and sent to their respective destinations based on the packet ID read from each header.

摘要： An encoding/transmitting apparatus that is used to transmit moving-picture data from a transmitting side to a receiving side through a transmission path and to subject the moving-picture data to streaming in the receiving side has an external-output request determining unit that monitors the state of a network. If the network assumes an undesirable state, the request determining unit causes a multiplex output unit to stop multiplexing data. When the network assumes a desirable state, the multiplex unit starts multiplexing the data again. A video encoding unit and an audio encoding unit keep encoding data, whether the multiplex output unit is multiplexing data or not. When the area occupied by encoded data in an encoded-video-data storage unit and the area occupied by encoded data in an encoded-audio-data storage unit exceed a predetermined value, the encoding units stop encoding data, and wait until the area occupied by encoded data sufficiently decreases.
