Abstract
An apparatus performs efficient coding techniques to more efficiently determine an availability of neighboring video data units determined for the current video data unit. The apparatus comprises an availability determination unit that maintains an availability counter. The availability determination unit determination unit increments the availability counter after each of the plurality of video data units are processed and determines, based on the availability counter, whether one or more of the plurality of video data units (i) have been previously processed and (ii) are available for use as neighboring video data units in the processing of a current one of the plurality of video data units video data units. The apparatus further processes the current video data unit based on the determination of whether one or more of the neighboring video data units are available.
