| JCTVC-U0078 CE2 : Test 5 on intra block copy constraints on prediction.
Proposal: Disabling IBC from CTUs where 8x8 biprediction is used. 5.1 intends to trade the additional memory accesses for IBC (once filtered, once unfiltered) against the current worst case. This constraint does not apply to the current and previous CTU, which are assumed to be available in cache. 5.2 uses IBC only when bi-prediction is not used in current slice. 5.3 is similar, but allows joint usage of IBC and bipred, if the latter uses integer MC. 5.4 is similar to 5.1, allowing joint usage of IBC and bipred, if the latter uses integer MC.
