Abstract： |
A video coding method includes carrying out in frame coding on the first frame of image to obtain movement vector by making movement estimation on the first frame of coded image, obtaining bit stream of movement vector by using variable length coder to make entropy coding, obtaining calibration bit stream by making channel coding after step size quantization and obtaining residual error image by utilizing current frame of image and antiquantization result to derive difference, utilizing transform quantization coefficient to obtain residual error bit stream, forming code stream by said bit stream and movement vector and forming output code stream by said code stream and calibration bit stream. |
