Abstract
Techniques for performing inverse transform operations on high bit-depth video data are described. A video decoder may receive encoded video data encoded at a first bit-depth in an encoded video bitstream. The video decoder may determine one or more of a dequantization shift or a mid-transform shift based on information in the encoded video bitstream, and perform an inverse transform on the encoded video data at a second bit-depth using the dequantization shift and the mid-transform shift, wherein the second bit-depth is lower than the first bit-depth.
