For the first coefficient (DC, unless block type is 0), we look at the (already encoded) blocks above and to the left of the current block. The context index is then the number (0,1,or 2) of these blocks having nonzero coefficients. After decoding a coefficient, the measure is determined by the size of the most recently decoded coefficient. Note that the intuitive meaning of this measure changes as coefficients are decoded, e.g., prior to the first token, a zero means that my neighbors are empty while, after the first token, because of the use of end-of-block, a zero means we just decoded a zero and hence guarantees that a non-zero coefficient will appear later in this block. However, this shift in meaning is perfectly OK because our context depends also on the coefficient band (and since zigzag positions 0, 1, and 2 are in distinct bands). */ public const int
