| #### 9.9 DCT Coefficient Probability Update {#h-09-09} |
| |
| |
| This field contains updates to the probability tables used to decode |
| DCT coefficients. For each of the probabilities in the tables, there |
| is an `L(1)` flag indicating if the probability is updated for the |
| current frame, and if the `L(1)` flag is set to `1`, there follows an |
| additional 8-bit value representing the new probability value. These |
| tables are maintained across interframes but are of course replaced |
| with their defaults at the beginning of every key frame. |
| |
| The layout and semantics of this field will be taken up in |
| Section 13. |
