Template matching prediction is combined with additional coding tools to provide a robust set of coding/decoding tools by advantageous use of syntax elements. Some of the additional coding tools comprise matrix intra prediction, intra sub-partitioning, low frequency non-separable transform, multiple transform selection. |
| Claim: |
1. A method, comprising: signaling that at least a first and a second coding tool are used on a video block; and encoding the video block using said first and second coding tools wherein template matching prediction is used and LFNST transform kernels corresponding to planar modes are used, or template matching prediction is used and multiple transform selection flag is not signaled and transform selection is determined from block dimensions. |
| Claim: |
2. An apparatus, comprising: a processor, configured to: signal that at least a first and a second coding tool are used on a video block; and encode the video block using said first and second coding tools wherein template matching prediction is used and LFNST transform kernels corresponding to planar modes are used, or template matching prediction is used and multiple transform selection flag is not signaled and transform selection is determined from block dimensions. |
| Claim: |
3. A method, comprising: parsing a video bitstream to determine at least a first and a second decoding tool for a video block; and decoding the video block using said at least first and second coding tool to be used on said video block wherein template matching prediction is used and LFNST transform kernels corresponding to planar modes are used, or template matching prediction is used and multiple transform selection flag is not signaled and transform selection is determined from block dimensions. |
| Claim: |
4. An apparatus, comprising: a processor, configured to: parse a video bitstream to determine at least a first and a second decoding tool for a video block; and decode the video block using said at least first and second coding tool to be used on said video block wherein template matching prediction is used and LFNST transform kernels corresponding to planar modes are used, or template matching prediction is used and multiple transform selection flag is not signaled and transform selection is determined from block dimensions. |
| Claim: |
5. The method of claim 1, wherein a general constraint flag is used for TMP to indicate deactivation. |
| Claim: |
6. The method of claim 1, wherein TMP is used where LFNST transform kernels corresponding to planar modes are used. |
| Claim: |
7. The method of claim 1, disallowing multiple transform selection with template matching prediction. |
| Claim: |
8. The apparatus of claim 2, wherein TMP is used for luma and chroma components, and syntax is used to signal use of TMP for both luma and chroma components. |
| Claim: |
9. The apparatus of claim 2, wherein template matching is used on luma components with a same position of matching block used for chroma components. |
| Claim: |
10. The apparatus of claim 2 4, wherein prediction candidates from inside and outside a coding tree unit are allowed. |
| Claim: |
11. The method apparatus of claim 2 4, wherein SIMD is used for computation of template differences. |
| Claim: |
12. The method of claim 3, wherein a general constraint flag is used for TMP to indicate deactivation. |
| Claim: |
13. The method of claim 3, wherein TMP is used where LFNST transform kernels corresponding to planar modes are used. |
| Claim: |
14. The method of claim 3 disallowing multiple transform selection with template matching prediction. |
| Claim: |
15. The apparatus of claim 4 wherein TMP is used for luma and chroma components, and syntax is used to signal use of TMP for both luma and chroma components. |
| Claim: |
16. The apparatus of claim 4, wherein template matching is used on luma components with a same position of matching block used for chroma components. |
| Claim: |
17. The apparatus of claim 4, wherein prediction candidates from inside and outside a coding tree unit are allowed. |
| Claim: |
18. The method apparatus of claim 4 wherein SIMD is used for computation of template differences. |
