Abstract:
Described tools and techniques relate to signaling for DC coefficients at small quantization step sizes. The techniques and tools can be used in combination or independently. For example, a tool such as a video encoder or decoder processes a VLC that indicates a DC differential for a DC coefficient, a FLC that indicates a value refinement for the DC differential, and a third code that indicates the sign for the DC differential. Even with the small quantization step sizes, the tool uses a VLC table with DC differentials for DC coefficients above the small quantization step sizes. The FLCs for DC differentials have lengths that vary depending on quantization step size.

Claim (Index 33):
A computing device comprising a processor and memory, wherein the computing device implements a video encoder configured to perform operations comprising:\n determining a quantization step size, wherein one or more syntax elements in a bit stream indicate the quantization step size; determining that a VLC for a DC differential for a DC coefficient is an escape code in a variable length code (VLC) table, the VLC table including different VLC values associated with different values for DC differentials, and the VLC table further including the escape code to indicate presence of a fixed length code (FLC); using the quantization step size to determine a length of the FLC for the DC differential for the DC coefficient, wherein the length of the FLC varies depending on the quantization step size; and encoding the FLC for the DC differential for the DC coefficient.
