Method and apparatus for audio and video end-to-end synchronization

摘要

A method and apparatus for synchronization of an audio/visual bitstream is transmitted by an encoder and received by a decoder by employing duplication or elimination of audio samples and video pixels. The invention enables clock synchronization between the encoder and a decoder with an unregulated clock oscillator so as to control the data reader by skipping ahead (eliminating a data element) or to pause (duplicating a data element) depending on whether the encoder clock is faster or slower than the decoder clock.
