    • The motion estimation techniques and video encoding device(s) described use a two dimensional pipeline to generate accurate motion estimation parameters for a current video block. The two dimensional pipeline uses previously calculated motion estimation parameters of relevant neighboring video blocks, including a preceding video block on a same row as the current video block, prior to the generation of the accurate motion vectors, motion vector predictors, and mode decision of the current video block The use of the two dimensional pipeline allows accurate motion vector prediction from neighboring video blocks previously not available, in the computation of motion vectors. Three engines may be used in the two dimensional pipeline, a fetch engine, an integer search engine and a fractional and spatial search engine. While the fetch engine and fraction and spatial search engine operate on one row, the integer search engine operates on another row.
    • 所描述的运动估计技术和视频编码设备使用二维流水线来为当前视频块生成准确的运动估计参数。 二维流水线在产生精确的运动矢量,运动矢量预测结果和模式决定之前使用相关的相邻视频块的先前计算的运动估计参数,相关的相邻视频块包括与当前视频块在同一行上的前一视频块 当前视频块在运动向量的计算中,使用二维流水线允许来自先前不可用的相邻视频块的精确运动向量预测。 三维引擎可以用于二维流水线,取数引擎,整数搜索引擎以及分数和空间搜索引擎。 虽然提取引擎和分数和空间搜索引擎在一行上操作,但整数搜索引擎在另一行上操作。

    • 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.
