ABSTRACT:
This disclosure describes deblock filtering techniques in which an in-loop deblock filter of a first codec is used as a post deblock filter of a second codec. A number of techniques are also described to facilitate input parameter adjustments and allow for the effective use of the filter with both codecs. The techniques can simplify the architecture of a device that includes multiple codecs operating according to different coding standards. Specifically, the different codecs can use the same deblocking filter regardless of whether the coding standard calls for in-loop filtering or whether post filtering is used. For example, a filter designed as an in-loop deblocking filter for a codec that complies with the ITU-T H.264 coding standard can be used as a post deblocking filter for MPEG-4 video.
