Benefits of technology

[0018]A video processing method capable of reducing system resources utilized for fast forward is provided. It is determined whether AV files are played with N multiples. If the AV files are played with N multiples, audio signals of the AV files are disabled. Video signals of the AV files are played with the N multiples. Post-processing is disabled and negligible frames of the AV files are not displayed by a display system.

Problems solved by technology

Playback quality is limited in that video files may not play smoothly in a video system comprising restricted memory resources, central processing unit (CPU) speed, or system architecture.
Limitations of embedded systems included blurry video images and failure of audio signal playback.

Abstract

A video processing method for AV synchronization resilience is provided. A first frame is decoded and displayed while a second frame is decoded for a predetermined period of time. It is determined whether the decoding time for the second frame exceeds a defined duration. If so, the first frame is continuously displayed during the decoding time for the second frame. The second frame is displayed while a third frame is decoded for a predetermined period of time.

Description

CROSS REFERENCE TO RELATED APPILCATIONS[0001]This application claims the full benefit and priority of provisional U.S. patent application Ser. No. 60 / 754,142, filed Dec. 27, 2005, entitled “Video Processing System Capable of Error Resilience and Video Processing Method for Same”, and incorporates the entire contents of the application herein.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to video processing, and in particular to a video processing system capable of error resilience and a video processing method for same.[0004]2. Description of the Related Art[0005]MPEG-4 is an ISO / IEC standard developed by the MPEG (Moving Picture Experts Group), the committee that also developed the Emmy Award winning standards MPEG-1 and MPEG-2. MPEG-4 is the successor to MPEG-1 and MPEG-2 video standards. The ISO standards committee implemented this standard in 1998. Instead of the current frame-based video technology, MPEG-4, has adopted the object-...
