摘要:本文介绍了TMS320C6416 DSP和MPEG-4ASP (Advanced Simple Profile )视频编码器在SP基础上新增的工具,详细阐述了基于该平台实现MPEG-4ASP视频编码器的软件优化方法,最后通过实验结果的比较展现了在嵌入式系统应用中ASP相对于SP编码器的优越性。由此可看出,在存储能力受限的情况下,采用ASP进行MPEG-4视频编码更为适合。
and VP3 (which never made it into a GTX 200 series part) added VC-1 decoding. For VP4, NVIDIA has added support for full decoding of MPEG-4 (Advanced) Simple Profile, better known as DivX or XviD. With this addition, NVIDIA can now offload the decoding of most ...
这些扩展通过支持更高的采样位深度精度和更高分辨率的颜色信息实现了更高质量的视频编码,包括称为Y’CbCr 4:2:2(= YUV 4:2:2)和Y’CbCr 4:4的采样结构:4。 Fidelity Range Extensions项目中还包括其他一些功能,例如4×4和8×8整数变换之间的自适应切换,编码器指定的基于感知的量化加权矩阵,高效的图片间无损...
