System and method for determining video subcarrier phase
摘要:
A system and method for determining phase of a subcarrier (e.g., a jittering video subcarrier). Various aspects of the present invention may comprise determining at least one weighting factor based, at least in part, on a subcarrier synchronization signal (e.g., a video synchronization signal). A first subcarrier phase sample and at least a second subcarrier phase sample may then be obtained. Subcarrier phase may then be determined by interpolating between the first subcarrier phase sample and the second subcarrier phase sample, where such interpolation (e.g., linear interpolation) may be based, at least in part, on the determined weighting factor(s).
