Claim:
1. A method of decoding video data, the method comprising: determining a first bit-depth of luma residual samples for a block of video data; determining a second bit-depth of predicted chroma residual samples for the block of video data; determining a bit-depth difference between the first bit-depth of the luma residual samples and the second bit-depth of the predicted chroma residual samples; adjusting the luma residual samples based on the bit-depth difference to produce bit-depth adjusted luma residual samples having a bit-depth that matches the second bit-depth of the predicted chroma residual samples; determining chroma residual samples for the block of video data based on the bit-depth adjusted luma residual samples and the predicted chroma residual samples; and decoding the block of video data based on the luma residual samples and the chroma residual samples.
