Here again, they have theoretically seen the different connectors, here we need to explain them a bit. As far as the definition of BNC goes… Please give them all or none. Bayonet, N type connector, Compact British Naval Connector Bayonet Nut Coupling Bayonet Neill Concelmann There is no definitive connector definition. I added digital displays to this list and included the DFP and DVI connectors. Glenn I added digital displays to this list and included the DFP and DVI connectors. Glenn Talk about the three larger pins, notice how they maintain the 75ohm impedance The best possible format, is RGBHV. No matter what we put into a display device, RED, GREEN, BLUE with Horizontal and Vertical Sync information is what is ultimately displayed. The big advantage to doing distribution in the format is that a display device needs to do NO video or sync processing. We no longer use Notch filters, Comb filters, and as well there is no sync decoding required. We remove all variables from a system. And we allow sufficient bandwidth through 5 cables to pass all of our information without fine detail loss. We are testing the technology We have found solutions… Unfortunately we aren’t entirely sure what the question is. Until the industry solidifies what it is going to do… It is hard to determine if it really works in real applications. 认识演示系统普遍计算机连接器 十五 针D-SUB 15 针连接器用于连接 普遍在旧Apple (萍果) 计算机阶层 认识演示系统工作站 13W3 13 针连接器内有3 sub-mini 同轴连接 Sun 工作站 SGI 工作站 绘图工作站 认识演示系统为什么BNC 连接器?
