LOW-FREQUENCY NON-SEPARABLE TRANSFORM INDEX SIGNALING IN VIDEO CODING

Abstract:

An example device for coding video data includes memory configured to store the video data and one or more processors implemented in circuitry and communicatively coupled to the memory. The one or more processors are configured to parse or signal all luma coefficients of a block of the video data from or to an encoded video bitstream. The one or more processors are configured to parse or signal at least one syntax element for the block after all the luma coefficients of the block are parsed or signaled from or to the encoded video bitstream, wherein the at least one syntax element comprises at least one of a low-frequency non-separable transform index for the luma coefficients or a multiple transform selection index. The one or more processors are also configured to code the block in accordance with the at least one syntax element.
