Implementation of Both High-Speed Transmission and Quality of System for Internet Protocol Multicasting Services

摘要

The paper introduces both high-speed transmission and quality of system to offer the lnternet sen ices on a MFC (Hybrid Fiber Coaxial) network. This utilizes modulating the phase and the amplitude to the signal of the IPMS (Internet Protocol Multicasting Service). An IP-cable transmitter, IP-cable modem, and IP-cable management servers that support 30-Mbps IPMS on the HFC were developed. The system provides a 21 Mbps HDTV transporting stream on a cable TV network. It can sustain a clear screen for a long time.
