REDUCED COMPLEXITY TRANSFORMS FOR HIGH BITDEPTH VIDEO CODING

A device for decoding video data receives encoded video data encoded at a first bit-depth; receives in an encoded video bitstream for the video data one or more syntax elements; determines a dequantization shift and a mid-transform shift based on the one or more syntax elements; and performs an inve...

description A device for decoding video data receives encoded video data encoded at a first bit-depth; receives in an encoded video bitstream for the video data one or more syntax elements; determines a dequantization shift and a mid-transform shift based on the one or more syntax elements; and performs an inverse transform of the encoded video data at a second bit-depth using the dequantization shift and the mid-transform shift to determine residual values for a block of video data, wherein the second bit-depth is different than the first bit-depth.
