Comparison between Integer Transform and DCT in H.264/AVC
Xiaorong Gao · Modern Electronics Technique · 2008
Digital video is widely applied in communications and broadcasting.Video and media information dealt with in internet is hotspot in China.MPEG and VCEG give a better standard,which is called H.264/AVC.In the article,the purpose of research on H.264 and the theory of DCT are explained.To reduce calculation,integer transform of macro block in H.264 is analysed.Coding ways in H.264,and difference between integer transform and DCT are expatiated.The fast way of integer transform called program of butterfly is shown.This is different from traditional DCT.
