我们报告了一种专门设计的手语视频序列编码技术，假设该技术用于手语电信，例如使用低比特率的移动可视电话。该技术由梯度编码、优先宏块编码和未编码编码三种方法组成。这些方法基于根据图像各部分重要性的评估为每个宏块分配一定数量的比特的思想。它们是在计算机上实现的，手语对话短片的编码数据由聋人受试者进行评估。结果，证实了该技术的有效性。
We report a specially designed encoding technique for sign language video sequences supposing that the technique is for sign telecommunication such as that using mobile videophones with a low bitrate. The technique is composed of three methods: gradient coding, precedence macroblock coding, and not-coded coding. These methods are based on the idea to distribute a certain number of bits for each macroblock according to the evaluation of importance of parts of the picture. They were implemented on a computer and encoded data of a short clip of sign language dialogue was evaluated by deaf subjects. As a result, the efficiency of the technique was confirmed.
