Video processing for electronic cinema
First Claim
1. A video processing system comprising:
- a frame buffer that is configured to;
receive incoming video images at a cinema frame rate of 24 frames per second, and providing outgoing video images at an outgoing frame rate that is an integer multiple of the cinema frame rate, and a display system that is configured to render the outgoing video images at a standard television resolution at the outgoing frame rate.

Abstract
A video processing system directly upsamples cinema material to a video frame rate that is a multiple of the fundamental cinema frame rate of 24 frames per second. A video display processor is configured to directly accept video images at a variety of frame rates, including the cinema frame rate of 24 fps. A frame buffer is suitably configured to accept the video images at the recorded frame rate and provides a corresponding video stream at a frame rate that is an integer multiple of the recorded frame rate. By providing the video stream at this frame rate, the anomalies and artifacts caused by non-integer or non-uniform upsampling are avoided. Correspondingly, a video processor is configured to provide the video images at standard television resolutions, but at the original recorded frame rate, to minimize temporal anomalies and artifacts.

10. A video processor that is configured to:
-
receive encoded video information whose encoding is based on a cinema frame rate of 24 frames per second, and decode the encoded video information to form decoded video images at the cinema frame rate and at a standard television resolution of 1280 by 720 pixels. - View Dependent Claims (11, 12, 13)
