EMBEDDED CLOCK RECOVERY AND DIFFERENCE FILTERING FOR AN MPEG-2 COMPLIANT TRANSPORT STREAM

摘要

A method of decoding a bitstream having an embedded clock, where the clock reference data is recovered from the bit stream. The clock reference data is combined, typically subtracted, from the system time clock to generate a result. This result is input to a pulse width modulator to form a pulse train, which is used to generate an input to a timing device.
