At the time of writing, the PC video input (VGA-DVI) and the document camera (DVI-HDMI) on the Cisco TelePresence codec operate at 1024×768 resolution with a refresh rate of 60Hz. The PC must be configured to output this resolution and refresh rate on its VGA output interface. Likewise, the document camera must be configured to output this resolution and refresh rate on its DVI output interface. The majority of PCs on the market at the time the product was designed use 1024×768 resolution and VGA interfaces, although an increasing number of models are beginning to support higher resolutions and are beginning to offer DVI and even HDMI interfaces instead of, or in addition to, VGA. Future versions of the Cisco TelePresence codec might support additional resolutions, refresh rates, and interface types for these connections.
VGA is an analog interface. DVI comes in three flavors: DVI-A that is analog, DVI-D that is digital, and DVI-I that can dynamically sense whether the connected device is using analog (DVI-A) or digital (DVI-D). It is worth mentioning that the first generation Cisco TelePresence codec offers a DVI-A connector for the PC connection. The other and of the cable that attaches to the PC is VGA. So the signal from the PC is a VGA analog to DVI-A analog connection. Now we will introduce you the VGA and DVI fiber video converter from our fiberstore.
