<P>PROBLEM TO BE SOLVED: To provide a contents data distribution apparatus capable of reproducing video and audio synchronously with each other, which cannot have been solved by methods and apparatuses of prior arts. <P>SOLUTION: The contents data distribution apparatus includes: a storage means that stores contents data including video and audio frames each with reproduction time information recorded therein; a frame data extract means that extracts the video and audio frames from the contents data; a frame data decoding means that decodes the extracted video and audio frames; a multiplex control means that re-encodes and multiples the decoded video and audio frames together with a control signal; and a transmission means that transmits the multiplexed data to a reception terminal, and the multiplex control means applies multiplex control to the video frame so that the video frame is multiplexed with the audio frame with information on one-preceding reproduction time to that of the corresponding video frame recorded therein in the case of applying re-encoding and multiplexing the video and audio frames. <P>COPYRIGHT: (C)2007,JPO&INPIT |
