Abstract
Techniques and systems are provided for processing video data. For example, an apparatus (e.g., a coding device, such as an encoder) can receive a residual portion of a block of a frame of the video data. The block is a first block in a row of the frame. The apparatus can receive a quantization parameter (QP) value determined for the residual portion of the block, and can determine all transform coefficients of the residual portion of the block have zero values. The transform coefficients can include quantized transform coefficients. The device can compare the received QP value determined for the residual portion of the block to a threshold QP value, and can determine a final QP value for the residual portion of the block based on whether the received QP value is greater than the threshold QP value.
