Abstract:
Systems and methods of filtering video data using a plurality of filters are disclosed. In an embodiment, a method includes receiving and decoding a plurality of filters embedded in a video data bitstream at a video decoder. The method includes selecting, based on information included in the video data bitstream, a particular filter of the plurality of filters. The method further includes applying the particular filter to at least a portion of decoded video data of the video data bitstream to produce filtered decoded video data.

Claim (Index 5):
An apparatus for decoding video data, the apparatus comprising:\n a video decoding processor configured to decode video data of a first unit of pixels of at least one frame, a second unit of pixels of the at least one frame, filter selection information for the first and second units of pixels, and filter data embedded in a video data bitstream at a video decoder, the decoding comprising reconstructing pixel values of the pixels of the first and second units of the at least one frame using one of intra-frame prediction or inter-frame prediction; and a memory configured to store the reconstructed pixel values of the first and second units of pixels; wherein the video decoding processor is further configured to:\n calculate a first variance value of reconstructed pixel values for pixels of the first unit of pixels; \n calculate a second variance value of reconstructed pixel values for pixels of the first unit of pixels; \n determine for the first unit of pixels, a first plurality of filter coefficients based on the filter data, the filter selection information, and the first variance value; \n determine for the second unit of pixels, a second plurality of filter coefficients based on the filter data, the filter selection information, and the second variance value; and \n apply the first plurality of filter coefficients to a first reconstructed pixel value of the first unit of pixels and the second plurality of filter coefficients to a second reconstructed pixel value of the second unit of pixels to produce filtered decoded pixel values of the first and second units of pixels.
