ABSTRACT:
When one video image (e.g., second video image) is blended or synthesized to video image (e.g., main video image), time base correction is made between both video data. A video data processing apparatus comprising a first video generator generating a first video data having an arbitrary frame rate, a second video generator generating a second video data having an arbitrary frame rate different from the first video data, and a synchronization controller using video reproduction time managed by the first video generator as a reference time, and correcting video reproduction time of the second video generator shifted from the reference time by repeatedly using the second video data to obtain frame synchronization.
