    Abstract: An inter/intra-frame predictive encoding method for video coding is provided to efficiency perform predictive encoding by decreasing the number of motion vectors to be encoded and load for predicting motion. An encoded block unit is expanded to more than one super macroblock comprising a bigger size than a 16x16 macroblock(S101). Each super macroblock is divided into sub brocks having various sizes(S102). Internet-frame prediction for the divided sub blocks is performed(S106). One of the predictions is selected and encoded as a predictive encoding(S107).

    Abstract: A fast inter-layer prediction mode decision method in scalable video coding is provided to process a scalable video encoding process in real time by making an encoding process fast. A video frame to be encoded is inputted to each layer(S100). Motion encoding of a lower layer is performed with regard to the input video frame(S101). A decision block according to the coding result of the lower layer corresponds to motion encoding of an upper layer. Prediction candidate block modes of the upper layer are determined by motion vector information according to the motion encoding result of the lower layer(S103). Rate-distortion costs are calculated about the determined prediction candidate block modes(S117). A final encoding block mode is determined by using the rate-distortion costs(S118).
