Multimedia network communication comprehensive experiment system

Abstract

The invention discloses a multimedia network communication comprehensive experiment system, comprising a digital television system, a campus network, a router, an SDH (synchronous digital hierarchy) transmission looped network, a comprehensive service support platform and an IPTV (internet protocol television) network; the existing digital television laboratory is used for providing a signal source, the signal is scheduled by using an IP (internet protocol) packaging technology and the configuration of a service gateway, an HFC (Hybrid Fiber Coaxial)-based and full-IP network bearing mode is established for transmission, networking technologies of EPON (Ethernet passive optical network), EPON+LAN (local area network), EPON+WALN (wireless local area network), EPON+EOC (Ethernet over coax) and the like are adopted at the access end, and finally the aim of providing services such as television, broadcasting, interactive television, internet accessing, voice and message service are provided for a user at the terminal. The invention aims to establish an opening experiment education system which integrates specialty, comprehensiveness and openness, has excellent software environment and advanced hardware environment and can perform comprehensive training on the scientific spirit, the practical capability and engineering attainment of students.

Description

technical field [0001] The invention relates to the field of Next Generation Broadcasting (NGB) (Next Generation Broadcasting), in particular to a comprehensive experiment system for multimedia network communication based on NGB technology. Background technique [0002] China's Next Generation Broadcasting Network (NGB) (Next Generation Broadcasting) is based on the achievements of cable TV digitalization and mobile multimedia broadcasting (CMMB), and is supported by the core technology of "high-performance broadband information network" independently innovated. my country's national conditions, the "triple play", the combination of wired and wireless, the whole network of the next generation of radio and television network. The core transmission bandwidth of NGB will exceed 1 gigabit per second, and the guaranteed access bandwidth of each household will exceed 40 megabits per second. The "one-stop" service of "integration" has made TV the most basic and convenient informati...
