Abstract
A clock recovery method for a TDM digital video signal and a transmitting/receiving apparatus for the clock recovery method are disclosed. A transmitter inserts a user clock code containing a predetermined number of points into the digital video signal during TDM processing and transmits the digital video signal. A receiver receives the TDM digital video signal and detects the user clock code from the TDM digital video signal. It counts a reference clock signal and recovers a transmission clock signal in an LMS algorithm using the user clock code and the count value.
