| ### Section 18: Interframe Prediction {#h-18-00} |
| |
| |
| Given an inter-prediction specification for the current macroblock, |
| that is, a reference frame together with a motion vector for each of |
| the sixteen Y subblocks, we describe the calculation of the |
| prediction buffer for the macroblock. Frame reconstruction is then |
| completed via the previously described processes of residue summation |
| (Section 14) and loop filtering (Section 15). |
| |
| The management of inter-predicted subblocks and sub-pixel |
| interpolation may be found in the reference decoder file `predict.c` |
| (Section 20.14). |
