20090119571 - 64b/66b coding apparatus and method: A system and method for transmitting digital data over a transmission medium includes receiving digital values representing a plurality of N-bit characters to be output over the transmission medium, each N-bit character being either a data character or a control character. A determination is made as to which of the... Agent: Blakely Sokoloff Taylor & Zafman LLP
