VIDEO CODING AND DECODING - A simplified explanation of the abstract
This abstract first appeared for US patent application 18503970 titled 'VIDEO CODING AND DECODING
Simplified Explanation
A method of encoding a motion information predictor index involves generating a list of motion information predictor candidates, selecting one as an Affine Merge mode predictor when an Affine Merge mode is used, and selecting one as a non-Affine Merge mode predictor when a non-Affine Merge mode is used. The selected candidate is then used to generate a motion information predictor index using CABAC coding, with some bits being bypass CABAC coded.

Original Abstract Submitted
A method of encoding a motion information predictor index, comprising: generating a list of motion information predictor candidates; when an Affine Merge mode is used, selecting one of the motion information predictor candidates in the list as an Affine Merge mode predictor; when a non-Affine Merge mode is used, selecting one of the motion information predictor candidates in the list as a non-Affine Merge mode predictor; and generating a motion information predictor index for the selected motion information predictor candidate using CABAC coding, one or more bits of the motion information predictor index being bypass CABAC coded.
