    Abstract: Techniques for encoding N-binary symbol (NB) source data vectors into M- binary symbol (MB) encoded vectors, M>N>0, are provided. Techniques for decoding are also provided. Exemplary coding and decoding apparatuses are presented, as is an exemplary 8B/10B encoding scheme. Encoded vectors may be disparity dependent or disparity independent. In assigning encoded vectors that have one or more individual binary symbol changes compared with their source data vectors, preference can be given to encoded vectors that are balanced and disparity independent. Whole-vector complementation and individual changes of one or more binary symbols can advantageously be performed substantially in parallel.

    Abstract translation: 提供了用于将N-二进制符号（NB）源数据向量编码成M-二进制符号（MB）编码向量的技术，M> N> 0。 还提供了解码技术。 呈现了示例性编码和解码设备，如同示例性8B / 10B编码方案。 编码矢量可以是视差依赖性或视差独立性的。 在分配与它们的源数据矢量相比具有一个或多个单独的二进制符号改变的编码矢量时，可以优选平衡且不相关的编码矢量。 一个或多个二进制符号的全矢量互补和个体改变可以有利地基本上并行地执行。

    Abstract: A method and apparatus are described for coding a frame of N-bit bytes into a frame of coded M-bit bytes wherein M > N > 0 and wherein said frame has a frame boundary including the steps of storing a frame of M-bit bytes; providing a code containing a set of M-bit bytes which is a subset of all possible M-bit bytes; for each of the 2
    N possible N-bit bytes there is a corresponding member in said set; each of said members of said code has a sequence of bits having a binary state selected from one of three values such that if the state of one of the bits is changed, a resulting M-bit byte is not a member of the code; one of the members of the code is a comma used to identify the frame boundary; the comma has a sequence of bits having a binary state selected from a first and second value such that the bit sequence of the comma is confined to one of said members of the code and the bit sequence of the comma does not occur across a boundary between any combination of any other members of the code; assigning to each of said N-bit bytes in said frame said corresponding member from said code to form a coded frame corresponding to said frame; and storing said coded frame.

    Abstract: METHOD OF CODING TO MINIMIZE DELAY AT A COMMUNICATION NODE A method of coding control blocks for packet communication wherein the code for control information is restricted to a smaller subset having the property that subfields within the block can be recognized and perhaps decoded without the remainder of the encoded block having been received.
