FFmpeg supports decoding of " Sorenson Vector Quantizer 3 " ( fourcc SVQ3 ) and Sorenson Vector Quantizer 1 ( fourcc SVQ1 ) starting with version 0.4 . 7, released in 2003.

The frame-level quantizer is a number from 0 to 31 ( although encoders will usually omit / disable some of the extreme values ) which determines how much information will be removed from a given frame.

Theoretical results on quantizer designs was provided by R . Zamir and S . Shamai, while different frameworks have been proposed based on this result, including a nested lattice quantizer and a trellis-coded quantizer.

The Lloyd Max quantizer is actually a uniform quantizer when the input pdf is uniformly distributed over the range [ y _ 1-\ Delta / 2, ~ y _ M + \ Delta / 2 ).

Quantization is performed by taking each of the 64 " frequency " values of the DCT block, dividing them by the frame-level quantizer, then dividing them by their corresponding values in the quantization matrix.

On November 17, 2016, the Digital Video Broadcasting ( DVB ) Steering Board approved UHD-1 Phase 2 with a HDR solution which supports Hybrid Log-Gamma ( HLG ) and Perceptual Quantizer ( PQ ).

"' G . 727 "'was introduced at the same time as G . 726, and includes the same bit rates, but is optimized for quantizer to 3-bit quantizer and same for the higher modes.
