INTRA BLOCK COPY MODE FOR SCREEN CONTENT CODING |
摘要 |
A video block of a current picture may be coded in an intra block copy (IBC) mode. Weighted prediction may be disabled for the IBC-coded screen content video block. Fractional block vectors may be used for the chroma components of the IBC-coded video block. An interpolation filter may be utilized to generate chroma prediction samples for the video block. A decoded version of the current reference picture may be added to both reference picture list LO and reference picture list LI that are associated with the IBC-coded video block. When constrained intra prediction is applied, reference samples that may be used to predict an intra- coded video block may be limited to those in intra-coded neighboring blocks. The range of IBC searches may be restricted by imposing a maximum absolute value for block vectors. |
