Summary

Recommendation ITU-T J.1102 describes the interface specifications for IP-based switched digital video (SDV) using data over cable service interface specifications (DOCSIS) in a digital cable network. The cable broadcasting system has been changed to use resources efficiently and to transmit said resources in such a way that the varying needs of subscribers are easily accommodated. The interface specifications described in this Recommendation are defined according to Recommendation ITU-T J.1101, Functional requirements for IP-based switched digital video using data over cable service interface specifications. These specifications are designed to maintain quality of service (QoS) while using bandwidth effectively in a hybrid fiber/coaxial (HFC) network environment.
