| Abstract: |
A decoding method is disclosed. A flag is first decoded. The flag indicates whether a current block of a picture is decoded with a tool of a set of tools. The set of tools comprises tools using reconstructed samples of neighboring blocks decoded prior to the current block or using a block of the picture larger than a hardware unit. The flag is only decoded in the case where the current block has a parent hardware unit. A current block is then decoded responsive to the flag. |
| Claim: |
1-15. (canceled) |
| Claim: |
16. A decoding method, comprising: decoding from a bitstream a first block of a picture, said block being temporally predicted using a motion vector, said motion vector being predicted from a motion vector predictor obtained from a second block, said second block being encoded using a tool in which said second block is temporally predicted using a second motion vector resulting from a refinement of a first motion vector decoded from the bitstream, wherein the motion vector predictor is the first motion vector. |
| Claim: |
17. The decoding method of claim 16, wherein the refinement of the first motion vector for obtaining the second motion vector uses a template, only a part of the template located inside a same parent hardware unit as the current block being used, a hardware unit being a portion of a picture such that all computations inside said portion are done independently of any other portion of said picture. |
| Claim: |
18. A decoding apparatus, comprising at least one processor configured to perform: decoding from a bitstream a first block of a picture, said block being temporally predicted using a motion vector, said motion vector being predicted from a motion vector predictor obtained from a second block, said second block being encoded using a tool in which said second block is temporally predicted using a second motion vector resulting from a refinement of a first motion vector decoded from the bitstream, wherein the motion vector predictor is the first motion vector. |
| Claim: |
19. The decoding apparatus of claim 18, wherein the refinement of the first motion vector for obtaining the second motion vector uses a template, only a part of the template located inside a same parent hardware unit as the current block being used, a hardware unit being a portion of a picture such that all computations inside said portion are done independently of any other portion of said picture. |
| Claim: |
20. An encoding method, comprising: encoding in a bitstream a first block of a picture, said block being temporally predicted using a motion vector, said motion vector being predicted from a motion vector predictor obtained from a second block, said second block being encoded using a tool in which said second block is temporally predicted using a second motion vector resulting from a refinement of a first motion vector encoded in the bitstream, wherein the motion vector predictor is the first motion vector. |
| Claim: |
21. The encoding method of claim 20, wherein the refinement of the first motion vector for obtaining the second motion vector uses a template, only a part of the template located inside a same parent hardware unit as the current block being used, a hardware unit being a portion of a picture such that all computations inside said portion are done independently of any other portion of said picture. |
| Claim: |
22. An encoding apparatus, comprising at least one processor configured to perform: encoding in a bitstream a first block of a picture, said block being temporally predicted using a motion vector, said motion vector being predicted from a motion vector predictor obtained from a second block, said second block being encoded using a tool in which said second block is temporally predicted using a second motion vector resulting from a refinement of a first motion vector encoded in the bitstream, wherein the motion vector predictor is the first motion vector. |
| Claim: |
23. The encoding apparatus of claim 22, wherein the refinement of the first motion vector for obtaining the second motion vector uses a template, only a part of the template located inside a same parent hardware unit as the current block being used, a hardware unit being a portion of a picture such that all computations inside said portion are done independently of any other portion of said picture. |
