[0041]In order to solve the problems existing in the prior art, the present invention proposes a brand-new H.264 code rate control method, that is, a method for controlling the code rate of the current macroblock by using the edge direction of the current macroblock. In the processing of video images, the edge direction of the current macroblock can be determined, and among the macroblocks adjacent to the current macroblock, the macroblocks in the same edge direction have a strong correlation in the space domain, by determining the current macroblock The edge direction of the current macroblock can determine the macroblocks with strong spatial correlation with the current macroblock, and use these highly correlated macroblocks to predict the current macroblock, so that compared with the existing JVT-G012 algorithm, the current macroblock The prediction is more accurate and the rate control is more effective.
[0042] Based on the above introduction, the specific realization of...
