The invention claims a technology used for the frame of video coding prediction module of signalling. The instance in the video decoder is arranged for video data block to determine one set of possible intra-frame prediction module so that a set of possible intra-frame prediction module is equal to preset digital of the size of said preset digital is greater than or equal to 2. the video decoder is further configured to based at least in part on the set of most likely frame in the prediction mode representing the actual frame of the block in the prediction mode value for decoding and using the actual frame in the prediction mode of the block to be decoded. the video decoder is further configured to use the actual frame in the prediction mode of the block to be decoded such as by encoding or decoding the block. The video coder and video decoder can implement these techniques.

This disclosure describes techniques for intra-prediction mode signaling for video coding. In one example a video coder is configured to determine for a block of video data a set of most probable intra-prediction modes such that the set of most probable intraprediction modes has a size that is equal to a predetermined number that is greater than or equal to two. The video coder is also configured to code a value representative of an actual intra-prediction mode for the block based at least in part on the set of most probable intraprediction modes and code the block using the actual intra-prediction mode. The video coder may further be configured to code the block using the actual intra-prediction mode e.g. to encode or decode the block. Video encoders and video decoders may implement these techniques.
