Methods and equipment for encoding video data and computer-readable storage media

Abstract

The patent refers to methods and equipment for encoding digital data and storage media that are produced by machines. The example method includes the following steps: in the video bitstream, the first syntactic element specifies whether motion compensation based on the model is enabled; based on motion compensation based on the model being enabled, the second syntactic element in the video bitstream specifies the maximum number of candidates predicting the unified motion vector based on the subblock, where the value of the second syntactic element is constrained to a value different from that of the first syntactic element; and image encoding of video data based on the maximum number of predicted motion vectors based on sub-blocks. The patent refers to the method and equipment for encoding video data and the storage medium obtained by machine (in). The example method includes the following steps: in the video bitstream, the first syntactic element specifies whether motion compensation based on the model is enabled; based on motion compensation based on the model being enabled, the second syntactic element in the video bitstream specifies the maximum number of candidates predicting the unified motion vector based on the subblock, where the value of the second syntactic element is constrained to a value different from that of the first syntactic element; and image encoding of video data based on the maximum number of predicted motion vectors based on sub-blocks.
