Estimating the term…
In general, techniques are described for performing transform dependent de-blocking filtering, which may be implemented by a video encoding device. The video encoding device may apply a transform to a video data block to generate a block of transform coefficients, apply a quantization parameter to quantize the transform coefficients and reconstruct the block of video data from the quantized transform coefficients. The video encoding device may further determine at least one offset used in controlling de-blocking filtering based on the size of the applied transform, and perform de-blocking filtering on the reconstructed block of video data based on the determined offset. Additionally, the video encoder may specify a flag in a picture parameter set (PPS) that indicates whether the offset is specified in one or both of the PPS and a header of an independently decodable unit.
