Claim Text:
1. A method for processing video data, the method comprising: decoding a first block of video data and a second block of video data, wherein the first block of video data and the second block of video data share a common edge; determining a first luminance quantization parameter for the first block of video data and a second luminance quantization parameter for the second block of video data; for each of one or more chrominance components, determining a chrominance quantization parameter offset value; for each of the one or more chrominance components, calculating a chrominance quantization parameter used to configure a chrominance component deblocking filter for the common edge based on the first luminance quantization parameter for the first block of video data, the second luminance quantization parameter for the second block of video data, and the chrominance quantization parameter offset value for the chrominance component; for each of the one or more chrominance components, determining a strength for the chrominance component deblocking filter for the common edge based on the chrominance quantization parameter used to configure the chrominance component deblocking filter for the common edge; and for each of the one or more chrominance components, applying the chrominance component deblocking filter according to the determined strength to deblock the common edge, wherein calculating the chrominance quantization parameter used to configure the chrominance component deblocking filter for the common edge comprises:
