    • A method and system for reducing the complexity of block motion estimation is described. According to the invention, the block distortion measure is determined by calculating a partial error result using a proportion of pixels in the block, comparing the partial error result with a threshold value and rejecting blocks where the partial error result is greater than the threshold value, and calculating a full error result for non-rejected blocks only. The threshold value is a function of the current minimum partial error result, and is preferably the current minimum partial error result multiplied by a threshold constant λ. Another aspect of the invention provides a video transport scheme which exploits the different importance of both GOP and re-synchronisation levels. According to this aspect, an unequal loss protection (ULP) philosophy is utilized. That is, the bit stream data is partitioned into several parts according to different importance, and the parts are unequally protected against packet loss using forward error correction codes.
    • 描述了一种降低块运动估计复杂度的方法和系统。 根据本发明,通过使用块中的像素的比例来计算部分误差结果来确定块失真度量,将部分错误结果与阈值进行比较,并且拒绝部分错误结果大于阈值的块, 并仅计算未拒绝块的完整错误结果。 阈值是当前最小部分误差结果的函数,并且优选地是当前最小部分误差结果乘以阈值常数λ1。 本发明的另一方面提供一种视频传输方案,其利用GOP和重新同步级别的不同重要性。 根据这一方面,利用了不平等的损失保护(ULP)理念。 也就是说,根据不同的重要性将比特流数据划分成若干部分,并且使用前向纠错码对这些部分进行不均匀的保护以防止丢包。
