| Abstract: | H.264 dramatically improves the video compression efficiency by using many new coding techniques against some previous video coding standards.However,the computation burden also largely increases.The affection of the new coding techniques on compression performance is mainly discussed in this paper so that an optimal selection for the tradeoff between compression efficiency and computation burden can be decided in a real software or hardware implement of the algorithms. |
