Encoding and decoding information about a motion information predictor

A method of decoding information about a motion information predictor, comprising:

• decoding information for identifying one of a plurality of motion information predictor candidates using CABAC decoding;
• and
• using the decoded information to select the one of the plurality of motion information predictor candidates,
• wherein for the CABAC decoding of at least one bit of said information, a Merge mode, in which a block predictor is obtained from a first block predictor and a second block predictor divided by a boundary, uses the same context variable as another inter prediction mode that is not said Merge mode, wherein the boundary is filtered between the first and second block predictor.

A device for encoding information about a motion information predictor comprising:

• means for selecting one of a plurality of motion information predictor candidates;
• and
• means for encoding information for identifying the selected motion information predictor candidate using CABAC coding,
• wherein for the CABAC coding of at least one bit of said information, a Merge mode, in which a block predictor is obtained from a first block predictor and a second block predictor divided by a boundary, uses the same context variable as another inter prediction mode that is not said Merge mode, wherein the boundary is filtered between the first and second block predictor.
