Abstract
In a video processing system, a burst signal generating circuit receives a discontinuous burst signal and generates a continuous burst signal by using a phase locked loop. In the conventional video processing system, it is difficult to select a loop gain and loop bandwidth for generating a burst signal, since the performance characteristics of a phase locked loop are directly influenced by the presence of a sample and hold circuit in the phase locked loop. In order to solve this problem, in processing a digital video, a discontinuous burst signal is detected, and then during a burst signal, the phase locked loop operates by the discontinuous burst signal detected so that the continuous burst signal may be generated. When the burst signal is not present, the phase locked loop operates by a constant error value according to the continuous burst signal shifted 90 degrees in phase. Thereby, the continuous burst signal is generated.
