Abstract: A decoder decodes, from a bitstream for video, a syntax element indicating a first value of precision for intra prediction. The decoder decodes, from the bitstream for intra prediction of a block of the video, a second value associated with an intra prediction angle corresponding to a slope equivalent to a quotient of the second value divided by the first value. Based on the first value and the second value, a prediction of the block is generated using reference samples obtained for the block. The decoder generates a decoded block from the prediction of the block.
