Frame synchronization for a video receiver

摘要

An integrated circuit chip includes a frame synchronization module for use with a Fourier transform module and an equalizer, the frame synchronization module configured to: receive an indication of a channel response from the equalizer; compute a power spectrum of an incoming video signal by applying spectral analysis to the video signal; determine a particular sample point in the power spectrum with a higher energy level than other sample points in the power spectrum; and send an indication of the position of the determined sample point relative to an initial sample point of the power spectrum to the Fourier transform module.
