Enhancing the performance of video compression on display devices using macro block classification and H.264 AVC

Abstract

This paper presents a 30-frames/s H.264 intra encoder for digital video recorder or digital still camera applications. To achieve high throughput and low area cost for high-definition video, we apply the modified three-step fast intra prediction technique to reduce the cycle count while keeping the quality as close as full search. A macro block classification method is proposed for various video processing applications involving moving images. Based on the analysis of the Motion Vector field in the compressed video, we propose to classify Macro blocks of each video frame into different classes and use this class information to describe the frame content. In the proposed algorithm, macro block classification and H.264 results can work effectively on video processing applications.
