![]() ![]() Furthermore, multiple transmitters can deliver different videos over the same network via external switch devices, and you can select the correct signal through a web interface. ![]() To support even more displays, the receiver has another RJ-45 network port to act as an in-vehicle video Dais圜hain extender. At the display end, the VIP 1000-R receiver receives the data, decodes it, then broadcasts the video through not just one, but two Full HD HDMI outputs. The VIP 1000-T transmitter takes the source HDMI signal, encodes the video using the H.264 codec then sends that data over the 1000Mbps IP network. Instead of complex solutions to overcome the limitations of HDMI, the VIP 1000-T/R solution sends the video signal over commonly available network cables. ![]() The NEXCOM system manages to overcome distance limitations by leveraging widely-used networking standards that reliably deliver data over long distances. Unicast, Daisy Chain and Multicast for Multi-Display Support up to 100m NEXCOM’s VIP 1000T/R is a new E-mark certified in-vehicle HDMI extender over IP solution designed specifically for railway and bus public transport PIS and infotainment, that works over standard networking hardware, uses common industry standards, and outputs to multiple displays up to 100m away. This approach works well, but many video extenders are of dubious quality, often only intended for consumer applications and lacking the essential E-mark verification. The more efficient and widely used option is video extenders that transmit video data over an Ethernet network. One option is additional video sources closer to the screens, but that’s a costly approach that adds complexity. A typical 12-meter long city bus already exceeds the recommended limits of HDMI, so alternative video broadcast approaches are needed. The major problem with HDMI is the cable length limitations. ![]()
