Design and implementation of preprocessor for spatial fine granularity scalable coding

为了更好地运用空域精细可扩展编码算法,提出了一种编码预处理器的设计方案。该方案占用较少的外部存储空间缓存帧数据,充分利用数据操作之间的并行性和流水性,生成视频数据的多描述码流。仿真结果表明,该方案能满足空域精细可扩展编码算法的功能和实时性要求。

To apply Spatial Fine Granularity Scalable Coding （S-FGS） efficiently, a design and implementation of preprocessor was proposed. This scheme used small RAM to store frame data. Moreover, parallel and pipelined data could be effectively applicable to this scheme. The analysis based on the simulation of the preprocessor shows that the scheme can meet the functional and real-time requirements of S-FGS.
