Overview

Data Over Cable Service Interface Specification (DOCSIS) is an international telecommunications standard that permits the addition of high-bandwidth data transfer to an existing cable TV (CATV) system. It is employed by many cable television operators to provide Internet access over their existing hybrid fiber-coaxial infrastructure. The Downstream (DS) NCP (Next Codeword Pointer) Decoder decodes NCP frames and there fore allows to convey plenty of information on the OFDM structure.
