| 928 | * the current mb needs to be updated. If mb qp modulation is enabled, then if |
| 929 | * the qp changes the quant param structure needs to be updated. Also to encoding |
| 930 | * the next mb, the current mb info is used as part of mode prediction or mv |

| 1947 | * The deviation between src and pred signal constitutes error signal. This error |
| 1948 | * signal is transformed (hierarchical transform if necessary) and quantized. The |
| 1949 | * quantized residue is packed in to entropy buffer for entropy coding. This is |
