摘要
The present invention relates to a frame rate control method for H.264. According to one aspect of the invention, the parameter initialization step of initializing the frame information and the buffer and the parameters including the initial quantization parameter (QP) value of the image; Coded Bit Amount for Previous Frame Average bit quantity of frames before the previous frame having a weighted value of and the same QP value as the previous frame's QP value The sum of the weighted values of and the QP value of the previous frame ( Frame complexity weights for predicting the target bit rate of the current frame using A complexity weighted updating step of predicting and calculating the complexity; Frame Complexity Weights for Predicting Target Bitrate of Current Frame The amount of bits that can be encoded per frame using And virtual buffer occupancy And target buffer levels Bit rate that can be encoded per frame Target bit rate for the current frame Calculating a target bit amount; Amount of occurrence bits for the index and QP value index Target bit rate for the current frame in the interval Through the loop to find the QP value for the current frame ( Determining a frame QP value; H.264, which is encoded with a QP value of a frame to be currently encoded determined by performing the complexity weighting update step, the target bit amount calculation step, and the frame QP value determination step. A frame rate control method is proposed.;H.264, bitrate control, adaptive, frame complexity, weight, frame-by-frame, QP
