System and method for clock skew compensation between encoder and decoder clocks by calculating drift metric, and using it to modify time-stamps of data packets

摘要

In a coordinated computer system for encoding, transmitting, and decoding a series of data packets such as audio and/or video data, there may be a skew between the clock used by an encoder and the clock used by a decoder. In a method and device for compensating for this clock skew, the decoder calculates a drift metric representing the clock skew and modifies the time stamps of the data packets based on the drift metric. The decoder also performs a sample rate conversion on the digital data, in order to compensate for the clock skew between the encoder and decoder.
