The 4K Over IP extender system allows the extension of a 4K video source, e.g. a PC or a set-top box, over a Gigabit IP network. The extender system is controlled remotely via the extended USB interface. This receiver can be connected to a transmitter (No. 38266 - not included) to set up a standard point-to-point system with maximum distances up to 100m (393ft). The transmitter can also be connected to multiple receivers so that a single device can be controlled from different consoles on the receiver side. A video wall can also be set up on the same private network using a dedicated Gigabit Ethernet switch (which supports 8kB jumbo frames).In addition to the audio signal embedded in HDMI, there are two additional audio channels (one audio output from the source and one for connecting a microphone on the far side) and an optical SPDIF port on the receiver for connecting a digital audio device or amplifier.The HDMI Over IP extender system has a practical, bi-directional IR amplifier system (20-60Khz), which enables the extension of remote control signals.This device is a typical solution for security management systems (control rooms or control rooms), remote server management (through the KVM control system) or extending AV signals over IP for monitoring industrial facilities. Another important application is large video wall installations (up to 16x16 screens) for digital signage and in stores.
