Abstract
This invention realizes correct adjustment of lip-syncing of video and audio on a decoder side. According to this invention, a plurality of encoded video frames given video time stamps VTS and a plurality of encoded audio frames given audio time stamps ATS are received and decoded from an encoder side, and the resultant plurality of video frames VFand plurality of audio frames AFare stored, a time difference which occurs due to a difference between the clock frequency of the reference clock of the encoder side and the clock frequency of the system time clock stc of the decoder side is calculated by a rendererand video frame output timing for sequentially outputting the plurality of video frames VFframe by frame is adjusted based on audio frame output timing for sequentially outputting the plurality of audio frames AFframe by frame, according to the time difference, resulting in realizing the lip-syncing with keeping sound continuousness.
