Abstract
Techniques for encoding and decoding media content, and more specifically to selecting filter coefficients for filtering coding artifacts from the encoded media content are described. The filter coefficients are selected by an encoder for a given frame based on a statistical record of one or more previous frames in a data stream. The statistical record indicates the effectiveness of different sets of filter coefficients in reducing encoding artifacts for the one or more previous frames. By employing the statistical record to select filter coefficients for the next frame in the data stream, the encoder is able to select the filter coefficients relatively quickly, reducing encoding latency while ensuring that a decoder is able to effectively decode the encoded frames.
