1.TM5 uses orginal source for full search but uses reconstructed pic for half per search, why?
2.when searching motion, only use Y component and igonore U, V ?
3.when deciding dct_type, use field correlation, but cannot understand totally. And, what is the advantage of different dct_type?
BTW: MSSG reference software is written in so good manner!!!!!!!
浏览了一下TM5的mpeg2编码器
博客围绕TM5展开,提出了几个关键问题,包括TM5全搜索和半像素搜索使用不同源的原因,搜索运动时仅用Y分量而忽略U、V的情况,以及决定dct_type时利用场相关性的原理和不同dct_type的优势。
