Coefficient coding with grouped bypass remaining levels for dependent quantization
Last updated:
Abstract:
The disclosure describes example techniques for determining a context used for encoding or decoding flags used to indicate a value of a coefficient. The techniques also relate to determining a quantization or dequantization factor to use for the coefficient. For determining the context and the quantization or dequantization factor, a video coder may determine values of flags used for encoding or decoding a previous coefficient and use the determined values of the flags for determining the context and the quantization or dequantization factor for the current coefficient.
