Claim 0:
1. A method for processing video, comprising:
determining, during a conversion between a current video block in a video data and a bitstream, two candidates and a combined inter-intra prediction flag for the current video block by a context model-based coding without referring to a combined inter-intra prediction flag of one or more neighboring video blocks to the current video block,
wherein the combined inter-intra prediction flag is used to indicate whether a combined inter-intra prediction mode is used, and
wherein, in the combined inter-intra prediction mode, a prediction signal of the current video block is generated at least based on an intra prediction signal and an inter prediction signal;

comparing a first information of the two candidates to determine whether to add at least one of the two candidates to a candidate list constructed for the current video block; and
performing, by at least applying the combined inter-intra prediction flag of the current video block, the conversion based on a result of the comparing,
wherein the first information of two candidates excludes a second information related to a coding mode, and
wherein the second information related to the coding mode comprises at least one of:
a flag of the coding mode, or
an intra mode that is used in the coding mode,

wherein a weight pair is determined according to a prediction mode of the one or more neighboring video blocks of the current video block,
wherein, when a neighboring video block is coded with the combined inter-intra prediction mode, the neighboring video block is treated as a block coded with an inter prediction mode which is a non-intra prediction mode,
wherein the one or more neighboring video blocks comprise a video block covering a location (xCb−1, yCb−1+(cbHeight<<a)) and a video block covering a location (xCb−1+(cbWidth<<a), yCb−1), wherein (xCb, yCb) is a location of a top-left sample of the current video block, cbWidth and cbHeight are a width and a height of the current video block, respectively, and a is determined using a cIdx of the current video block, and wherein cIdx is a variable specifying a color component index for the current video block.
