Abstract
A method for adaptive loop filtering is provided that includes determining a coefficient value for each coefficient position of an adaptive loop filter, applying the adaptive loop filter to at least a portion of a reconstructed picture using the coefficient values, and entropy encoding coefficient values into a compressed bit stream using predetermined short binary codes, wherein the short binary code used depends on the coefficient position of the coefficient value.

A method comprising:
- initiating an encoding of a video sequence to produce an encoded video sequence, wherein the encoding of the video sequence includes:
- encoding a plurality of coefficient values for an adaptive loop filter without encoding a coefficient value for a center position in the adaptive loop filter and without encoding any information for the coefficient value for the center position into the encoded video sequence;
- reconstructing an image in the video sequence;
- and
- applying the adaptive loop filter to a pixel value associated with the image using the plurality of coefficient values;
- distributing the encoded video sequence over a communication channel;
- and
- causing a decoding of the encoded video sequence in a decoder device, wherein the causing comprises receiving the encoded video sequence by the decoder device.
