Video data processing apparatus
First Claim
1. 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.

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.

9. A video data processing method of blending a first video data generated using hardware processing and having an arbitrary frame rate and a second video data generated using software processing and having an arbitrary frame rate different from the first video data, comprising:
-
comparing a frame rate of the first video data with a frame rate of the second video data; and
blending the same frame of the second video data to continuous each frame of the first video data several time, and thereby, offsetting a difference between the frame rates. - View Dependent Claims (10, 11)

12. A video data processing apparatus comprising:
-
first video generator means for generating a first video data having an arbitrary frame rate using hardware processing;
second video generator means for generating a second video data having an arbitrary frame rate different from the first video data;
means for using video reproduction time managed by the first video generator means as a reference time, and correcting video reproduction time of the second video generator means shifted from the reference time by repeatedly using the second video data to obtain frame synchronization; and
means for omitting a generation of a video frame when video generation of the second video generator means is delayed from video generation of the second video generator means.
