Method for Processing Video Frames, Video Processing Chip, and Motion Estimation/Motion Compensation MEMC Chip

A method comprising:

• receiving, by a Motion Estimation/Motion Compensation (MEMC) chip, a transport frame stream sent at a second frame rate by a video processing chip, wherein the transport frame stream comprises multiple video frames and at least one invalid frame, wherein a resolution of the multiple video frames and the at least one invalid frame is a second resolution, and wherein the second frame rate is a frame rate agreed upon in advance by the video processing chip and the MEMC chip, and wherein the second resolution is a resolution agreed upon in advance by the video processing chip and the MEMC chip;
• obtaining, by the MEMC chip, the multiple video frames in the transport frame stream, wherein a frame rate of the obtained multiple video frames is a first frame rate;
• and
• performing, by the MEMC chip, Motion Estimation/Motion Compensation on the multiple video frames of the first frame rate, to generate a display frame stream of a third frame rate, wherein the third frame rate satisfies a refresh rate for a display screen to display the display frame stream, and wherein the third frame rate is higher than the first frame rate.
