<pre> But i'm litle confused seen table 7.38 of Theora spec. How i understand we use only 8 bit values in coder (for quantized coefficient of block), but in table 7.38 is (for example token value = 22) i see tokenization of values more than 255? How it's possible? Extrabits for token value=22 is 10 bits. This mean we can present -512..+512 magnitude values for coeffs..... How it's possible? Ok. May be this is why when DCTed our 8-bits values we at result have 16-bits value out. Ok this is understand, but why realy thear are tokens fo 10-bits value? (Is it because we use quantization ?)</pre>
