Based on HEVC standard, decimal quantized coefficients are binarized through different methods, e.g. Truncated Unary, Truncated Rice (k-th order), Exp-Golomb, etc.

Considering the Truncated Rice method, I cannot understand the role of cmax parameter that completely changes the output. I have understood how the algorithm works, but I do not find any reference about that parameter. It seems that the Truncated Rice does not depend by cmax, however different outputs return for associated different values.

Comparing the two attached images, you can note the different binarized outputs based on cmax. Can you provide any reference that explains how the algorithm works based on cmax?

Could you add references to these screen shots, so we can read and understand the notation?

PS: I assume you have already read Transform Coefficient Coding in HEVC paper, but you still need more detailed information.
