Abstract
A computing device, such as a video encoder, uses respective positions of respective coefficients in a coefficient block to look up, in a lookup table, respective quantization offsets for the respective coefficients. Furthermore, the computing device determines, based at least in part on the quantization offsets for the one or more coefficients, respective quantized levels for the respective coefficients.
