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 method for estimating an available bandwidth of a network. A plurality of periodic time-stamp packets are transmitted to a receiving-party communication apparatus, which is connected to the network, through the network at a currently-set test transmission rate, and then a changing tendency of transmission delay time differences between the time-stamp packets is checked on the basis of reception times at which the receiving-party communication apparatus have received the respective time-stamp packets. When the transmission delay time differences are located outside a stable range and show a tendency to increase, the test transmission rate is set to a decreased value and the time-stamp packets are repeatedly transmitted at the decreased rate and when the transmission delay time differences are located outside the stable range and show a tendency to decrease, the test transmission rate is set to be an increased value and the time-stamp packets are repeatedly transmitted at the increased rate. A test transmission rate is determined as the available bandwidth when the transmission delay time differences are within the stable range.
