Patent ID: 8587721

Claim:
A method of processing a video signal, the method comprising: receiving the video signal of a source synchronous video broadcast which corresponds to a selected channel which is one of a plurality of channels of a broadcast spectrum, the video signal being analog signals, wherein the source synchronous video broadcast includes information which is representative of a frequency of a source clock, the method comprising: generating digitized data of the video signal by sampling a first number of samples of the video signal, which corresponds to the source synchronous video broadcast, using a local clock signal having a frequency which is different from the frequency of the source clock of the source synchronous video broadcast, the local clock being associated with a sampling rate; generating video data using the digitized data of the video signal which corresponds to the source synchronous video broadcast, the video data comprising a second number of samples of the video signal data, one or more samples of video signal data being modified if the first number is different from the second number; generating formatted video data blocks by arranging the video data into one or more lines or frames of video data; generating temporal reference signals wherein each temporal reference signal is associated with at least one formatted video data block; and outputting each formatted video data block and associated temporal reference signal.
