The Design And Application Of Training Platform For Triple Play

Between enterprises in the 21 st century competition in many degrees is talent competition, under the background of triple play, Colleges and universities need to adjust the curriculum of electronic majors, so as to adapt to the new situation better, so that students can adapt to social needs. Nanguang College in order to adapt to the development of the technology and media industries using their own resources, construction of the integrated training platform based on the full service network of NGB fusion.This paper based on the in-depth study on Key Technologies of triple play involves analysis, to design and build the can meet the various needs of the tri networks integration training platform, and platform development to meet the electronic professional related courses practice teaching needs the training project. The main research content of this paper is as follows:(1) This paper analyzes the background and development status of triple play. In this paper, the triple play relates to the video and audio codec technology, streaming media technology, digital rights management, content distribution networks, multicast technology, electronic program guide, video transcoding technique and synchronous digital hierarchy technology key technology in-depth study.This paper focuses on the access network scheme based on Ethernet passive optical network technology;(2)This paper constructs the construction scheme of the training platform of triple play, in the access terminal using the technology scheme of FTTH and FTTB + LAN, FTTB+EOC, FTTB+WLAN etc., and the technical characteristics of multicast and unicast channel separation of, in the end office, realize the mixing of the multi service, common cable transmission, in the terminal, CATV and data to achieve the separation of the use of signals;(3) Develop and design training program on the platform of the triple play, which can meet the needs of the practice teaching, the scientific research and the certification training of the electronic specialty.
