摘要

PPROBLEM TO BE SOLVED: To solve a problem that complexity in rate-distortion computations and the number of times of computations affect the time and resources required for identifying a prediction mode of a block, these computations may overload an encoder in accordance with the encoder and a system wherein the encoder operates, and it deteriorates an encoded video signal generated by the encoder as a result. PSOLUTION: A prediction mode for encoding data is selected using a reduced number of rate-distortion cost computations. This reduction in rate-distortion cost computations is caused by filtering the number of potential intra prediction modes based on two criteria. First, the number of potential prediction modes is reduced based on at least one characteristic of a quantization procedure performed during the encoding procedure. Second, the number of potential prediction modes is reduced based on an error value calculated for each of the potential prediction modes. PCOPYRIGHT: (C)2006,JPO&NCIPI

要解决的问题：为了解决速率失真计算的复杂性和计算的次数影响识别块的预测模式所需的时间和资源的问题，这些计算可能会使编码器过载编码器和其中编码器工作的系统，其结果是恶化了由编码器产生的编码视频信号。

解决方案：使用减少的速率失真成本计算来选择用于编码数据的预测模式。速率失真成本计算的这种减少是由于基于两个标准对潜在帧内预测模式的数量进行了过滤而导致的。首先，基于在编码过程中执行的量化过程的至少一个特征来减少潜在预测模式的数量。其次，基于针对每个潜在预测模式计算的误差值，减少潜在预测模式的数量。
