A Comprehensive Experimental System of Multimedia Network Communication

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 multimedia network communication comprehensive experimental system based on NGB technology. Background technique [0002] China Next Generation Broadcasting Network (NGB) (Next Generation Broadcasting) is based on the achievements of cable television digitization and mobile multimedia broadcasting (CMMB), supported by the core technology of independent innovation of "high-performance broadband information network", and is constructed to suit my country's national conditions The next-generation radio and television network that integrates the "three networks", wired and wireless, and the entire network. The core transmission bandwidth of NGB will exceed 1 gigabit per second, ensuring that each household’s access bandwidth exceeds 40 megabits per second, and it can provide high-definition television, digital video and audio programs, high...
