基于网络的分布式vga多媒体数字矩阵

Distributed VGA multi-media digital matrix based on network

Abstract

The utility model discloses a distributed VGA multi-media digital matrix based on network, which relates to the field of VGA multi-media digital matrix. The distributed VGA multi-media digital matrixcomprises an IP network (12) which is provided with a server (11), a compressor (13) and a decompression device (14), wherein the server (11) is communicated with the IP network (12), and the computer(20), the compressor (13), the IP network (12) and the decompression device (14) are communicated in turn, and the decompression device (14) is respectively connected with a display (30) and an audiofrequency power amplifier (40). The distributed VGA multi-media digital matrix simultaneously achieves the random switching of multi-path audio frequency and VGA signals, a signal path is supported by the IP network, the problems of limited transmission distance caused by signal attenuation are solved, since the distributed framework is adopted, matrix dilatancy is simple and fast, and actual switching volume can reach M*500*M*500 (M represents the quantity of servers).
本实用新型公开了一种基于网络的分布式VGA多媒体矩阵,涉及一种VGA多媒体矩阵领域。本实用新型包括IP网络(12),设置有服务器(11)、压缩器(13)和解压器(14);服务器(11)与IP网络(12)连通;计算机(20)、压缩器(13)、IP网络(12)和解压器(14)依次连通;解压器(14)分别与显示器(30)及音频功放器(40)连接。本实用新型同时实现了多路音频和VGA信号的任意切换;信号通路由IP网络承载,解决了因信号衰减导致传输距离受限的问题;由于采用分布式构架,矩阵扩容简单快捷,实际切换容量可达M×500×M×500(M表示服务器数量)。
