    摘要： All macro blocks (MB) decided as an “all_0”, “all_255” or “intra predicted” mode are transmitted as an “intra not coded” mode. A receiving terminal also separates “all_0”, “all_255” and “intra predicted” from the “intra not coded” mode, referring to pixels of a lower layer. “Inter coded && MVD=0” and “Inter coded && MVD!=0” modes are represented as “Inter coded”, and “Inter not coded && MVD=0” and “Inter not coded && MVD!=0” modes are represented as “Inter not coded”. As its result, coding modes on an I-picture can be reduced to two modes and coding modes on a P-picture, or a B-picture, can be lessened to four modes.

    摘要： A method and system for contour-based motion estimation for use with video images. The invention establishes corresponding contours (404, 414) in two images (402, 412) in a sequence of images, determines a motion vector which includes how the first contour (404) moved to become the second contour (414), and transmits the motion vector of the contour (414) in order to permit accurate display of the second video image (412). Preferably, boundary lines are removed from the contours before a comparison is made. The invention is computationally efficient and economical from a data transmission point of view, while enabling the production of accurate image.

    摘要： A predictive coding in a video coding system, which can enhance the coding efficiency by predictively coding DC coefficients of a block to be coded using DC gradients of a plurality of previously coded neighboring blocks. The predictive coefficient is selected according to the difference between the quantized DC gradients (coefficients) of a plurality of neighboring blocks of the block to be coded, and the DC coefficient of the block to be coded is predictively coded by the selected predictive coefficient, thereby enhancing the coding efficiency.
