Abstract

Methods and systems for performing at least one of video encoding and video decoding are disclosed. In one implementation the system includes a controller configured to determine a video standard associated with a portion of the video data each portion of the video data associated with one of a plurality of video standards. The controller is further configured to provide a set of the filter parameters which are associated with a video standard to be used for at least one of the video encoding and decoding and at least one filter configured to filter at least one reference pixel received from the reference pixel memory based at least in part on the provided set of filter parameters.
