摘要： An encoded packet transmitting apparatus includes a converting unit (103), which receives a packet encoded at a preset compression ratio, re-encoding the packet data obtained on decoding data of said input packet, at a compression ratio different from said preset compression ratio, to generate a packet, and outputting the so generated packet, a delay adding unit (105) for performing control so as to add preset delay to the packet output from the converting unit (103) for transmitting the resultant packet, a multiplexing unit (106) for multiplexing the packet encoded at a preset compression ratio and the packet encoded at a compression ratio different from the preset compression ratio and added by delay and for outputting the resultant multiplexed transmission packet.

摘要： The accuracy of time information set in a packet is improved. Time information calculator 24 calculates time information, using the encoding information received by control information receiver 23 and the encoded stream received by encoded stream receiver 21. When the time information is not pertinent, time information calculator 24 corrects the time information and outputs the corrected time information. Encoded stream packetizer 22 packetizes the encoded stream by setting the time information output by time information calculator 24 into the header portion.
