Method and system for generating video frames and correcting motion

Abstract

System and method for generating video frames. The system includes a frame generator which generates one or more intermediate frames based upon one base frames. Each of the base frames are comprised of a plurality of macroblocks. Furthermore, one or more of the macroblocks have a motion vector. The macroblocks are comprised of a plurality of pixels. In the frame generation process, the frame generator performs a number of steps such as: (i) determines whether frame generation is appropriate, (ii) examines the first and second base frames to check for the presence of textual characters, (iii) selects a frame generation method based upon information in the first and second frames, (iv) filters the generated frames. In one embodiment, the system includes a server computer having an encoder, a client computer having a decoder, and a network connecting the server computer to the client computer. In this embodiment, the frame generator resides and executes within the client computer and receives the base frames from the decoder.

         2 . A method for enhancing a video stream, comprising:
 receiving in a computer memory a first video frame;   receiving in the computer memory a second video frame defined at least in part by one or more pixel macroblocks corresponding to pixel patterns and corresponding one or more motion vectors selected to indicate movement of the one or more pixel patterns corresponding to the pixel macroblocks relative to similar one or more pixel patterns in the first video frame;   generating in the memory an intermediate video frame between the first and second video frames by scaling one or more of the motion vectors to produce one or more intermediate motion vectors corresponding to the one or more pixel macroblocks; and   applying a quantized filter to the one or more pixel macroblocks in the intermediate video frame.
