Abstract
Techniques for implementing video processing techniques are described. In one example implementation, a method of video processing includes determining, for a conversion between a current block of a video and a bitstream representation of the video, whether a combined inter and intra prediction (CIIP) coding technique is to be applied to the current block based on a characteristic of the current block. The CIIP coding technique uses an intermedia inter prediction value and an intermedia intra prediction value to derive a final prediction value of the current block. The method also includes performing the conversion based on the determining.
Claims17
A method for video processing, comprising:
- determining, for a conversion between a current block of a video and a bitstream of the video, whether a combined inter and intra prediction coding technique is to be applied to the current block based on at least one of a height H of the current block, or a width W of the current block;
- and
- performing the conversion based on the determining;
- wherein in response to the combined inter and intra prediction coding technique being to be applied to the current block, an intermedia inter prediction value and an intermedia intra prediction value is used to derive a prediction value of the current block;
- wherein in case W is greater than T1 or H is greater than T1, the combined inter and intra prediction coding technique is disabled for the current block, and wherein T1=64.
