发明名称 Sample rate converter for digital video signals having reduced phase error and sync point coincidence
摘要 A digital video signal processing device is capable of avoid phase difference of video signals in case of converting the rate of digital video signals. In case of converting the first digital video signal to the second digital video signal, the sync points of the first digital video signal and the second digital video signal can be coincided by coinciding the predetermined numbered clock timings of the first and second clocks with a clock synchronizing device. Since the rate is converted in utilizing a filter having a characteristic to coincide sync points of the first and second digital video signals, sync points of the first digital video signal and the second digital video signal can be coincided, so that the phase difference of video signals can be avoided in advance in either case.
