Patent

CA 2160614

A method is provided for synchronizing video data buffers in a system including: an encoder for encoding input data into a compressed data bitstream; an encoder buffer for storing the compressed data bitstream; a decoder buffer for receiving the compressed data bitstream, with a sum of an encoder buffer delay and a decoder buffer delay is constant; a variable rate transmission channel operatively connecting the encoder buffer and the decoder buffer; and a decoder for receiving and decoding the compressed data bitstream. The instantaneous encoder buffer delay is used to generate a control signal; the control signal is inserted into the compressed data bitstream following the encoder buffer. In an exemplary embodiment, each of the encoder and decoder performs encoding and decoding operations, respectively, in the Motion Picture Experts Group (MPEG) standard, using the VBV_DLY parameter of the MPEG standard as the control signal.
