摘要： A moving picture coding and/or decoding system includes an encoder (10) for coding input image data, a divider (14) for dividing a code string supplied from the encoder (10), into a plurality of code strings, a reorder (15) for arranging at least one of the plurality of code strings in the forward direction from the head to the end, and at least one of the other code strings in the backward direction from the head to the end. A variable-length coding system includes a code-word table for storing a plurality of code words so that the code words correspond to source symbols, and an encoder for selecting a code word corresponding to the source symbol inputted from the code-word table and for outputting the selected code word as coding data. The plurality of code words can be decoded in either of the forward and backward directions. The plurality of code words are configured so that the pause between codes can be detected by a predetermined weight of the code word (in the case of a binary code, the number of "1" or "0" in the code word).

摘要翻译： 运动图像编码和/或解码系统包括用于编码输入图像数据的编码器（10），用于将从编码器提供的代码串（10）分成多个代码串的分频器（14），重排序器 ），用于将多个代码串中的至少一个代码串设置在从头到尾的正向方向上，以及其他代码串中的至少一个从头到尾地向后方向排列。 一种可变长度编码系统包括用于存储多个码字以使码字对应于源码元的码字表和用于选择与从码字表输入的源码元相对应的码字的编码器和 用于输出选择的码字作为编码数据。 多个码字可以在前向和后向中的任一个上被解码。 多个码字被配置为使得可以通过码字的预定权重（在二进制码的情况下，码字中的“1”或“0”的数目）来检测码之间的暂停。
