Patent ID: 8743972

Claim:
A deblocking filter module for use in a video processing device that processes a video input signal in accordance with a plurality of coding parameters wherein the video processing device operates in a first mode with macroblock adaptive frame and field (MBAFF) processing enabled and a second mode with MBAFF processing disabled and a processing module generates a MBAFF flag that alternatively indicates one of: the first mode and the second mode, the deblocking filter module comprising: an adaptive deblocking filter, coupled to receive a plurality of samples and to produce a plurality of filtered samples in response thereto, the adaptive deblocking filter having at least one filter parameter that is controlled, and wherein the at least one filter parameter is controlled in response to a filter control signal to vary a filter strength from a first filter strength in the first mode of the MBAFF flag to a second filter strength in the second mode of the MBAFF flag; and a filter control module, coupled to the adaptive deblocking filter, that generates the filter control signal based on the MBAFF flag.
