A video coding system capable of encoding and/or decoding a video frame based on at least two different types of motion vector predictions. In one type, the motion vector predictor of a current block in the video frame is calculated using only the motion vector of a neighboring block which is directly above the current block. In another type, the motion vector predictor is calculated using the motion vector of a neighboring block located on the left side of the current block. In the former type, adjacent blocks located in the same row can be decoded independently of each other. In the latter type, adjacent blocks located in the same column can be decoded independently. The system may also be capable of conventional coding. An indication is used for indicating to the decoder side which type of motion vector predictor is used in the encoding. |
