Jiangxi Expressway Investment Group Hd Video Conference Planning Scheme

With the global information era, people do understand things, the exchange ofinformation from the basic approach has been through paper, pens, books,Voice andother advanced method through sound and light signals, etc., to be more accurate,faster, richer expression. On the demand driven, The multimedia computertechnology and communication base combination, and gradually developed into anew edge technologies---Multimedia Communication Technology Surgery,Videoconferencing is the use of communications networks to voice, video, data and otherinformation integrated together for long-distance transmission of multiMediabusiness, so that people in different places when communicating during both can heareach other’s voices, they can see each other’s image,And synchronous datatransmission, point to point, multipoint video conferencing new business.This thesis focuses Jiangxi Expressway Investment Group building tomainstream H.323system architecture definition video conferencing systemsengineering solutions put forward feasible. System requirements of the building ofinternational standard protocols, the system architecture for the mainstream H.323,also compatible with the future development of the SIP protocol; supports standard(H.239) dual stream function, and hould have a full HD data collaboration mode.Total system capacity of not less than15way HD1080P venue access, colleagueshave more than45sets of various speed and image quality terminal access, you canalso access the venue terminals, desktop terminals, software, terminals, IP telephoneterminal capabilities and support local network and Internet access, and enhance thesystem network scalability.Equipment using china telecom-class of design, with multiple redundant backupmechanism including line backup. Hot standby, power backup, and provide audiobackup port security system has good reliability and stability. The system provides animage needs a stable, reliable, consistency is good, not a mosaic. Pause. Jump; ensurepure sound synchronisation, error should be imperceptible. Network IP network withoutstanding ability to adapt, to ensure the effect of low bandwidth, network bandwidth to achieve lower case transmission1080P25frames/secondhigh-definition video effects, along with a strong network fault tolerance, in the endlost bearer network Pack of5%, still maintain a good audio and videocommunications, images are not affected.
