This draft new Recommendation describes the transmission specifications of IP-based switched digital video (SDV) using data over cable service interface specifications (DOCSIS) in a digital cable networks. The cable broadcasting system has been changed to use resources efficiently and transmit them to easily accommodate the varying needs of subscriber. Therefore, it is necessary to define the transmission specifications for J.1101 "Functional requirements for IP-based switched digital video using data over cable service interface specifications" which is supported the maintaining quality of service (QoS) and using bandwidth effectively in a hybrid fiber/coaxial (HFC) network environment.
