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： A packet type retransmission system for DMB services includes a DMB device for receiving multimedia data from a content provider, for converting the multimedia data to DMB data for DMB transmission, and for transmitting the DMB data. A broadcasting transfer medium transfers the DMB data transmitted through the DMB device. A DMB-IP converter receives the DMB data transferred through the broadcasting transfer media and converts the DMB data to packet based data. An IP based multimedia transmitting device outputs the packet based multimedia data converted through the DMB-IP converter to user devices.

摘要： Disclosed is a method for establishing a synchronization in a synchronous Ethernet system. Devices are classified according to the type of the devices, and a device having a highest class in the synchronous Ethernet system is detected, then it is determined if the device having the highest class is able to serve as the timing master. If so, the device having the highest class is able to serve as the timing master if only one such device is detected; otherwise, the timing master between devices having the highest class is selected through a collision algorithm.
