Over IP Extender

AV integrators are now increasingly turning to IP-based network solutions to extend signals from stationary video systems or distribute them within large environments and rooms.

These AV systems utilize the existing IP network infrastructure and offer a solution that is flexibly scalable within a wide variety of requirements and in all directions.



AV-over-IP is an AV technology that converts the input signal – based on the Ethernet network standard – into IP data packets using a transmitter and distributes these over the standard network. 

Receivers placed on the displays convert the data stream back into sound and image, which can then be played back via the corresponding target device.



The big advantage is that wherever there is a network connection, a corresponding transmitter or receiver can be integrated into the overall system. 

Transmitters or receivers can therefore work independently of one another and can be combined and switched depending on the hardware and network environment.


AV-over-IP systems are typically used in security management (control rooms), in server remote management (through the KVM control systems) or for extending the range of AV signals for monitoring industrial plants. Other important applications include large video wall installations (up to 16×16 screens) – such as those used in control rooms – as well as digital signage, plant monitoring and retail.

The transmitter can be connected to a single or to multiple receivers to create either a standard point-to-point control system with a maximum range of 100 metres, or a point-to-multipoint installation to provide the output signal at multiple locations. In addition, this last mentioned configuration allows a single source device to be controlled from multiple consoles.

The extender can handle USB 2.0 and HID signals for KVM functions as well as bidirectional analogue audio, IR and RS232 signals and is compatible with HDMI 2.0 and HDCP 2.2/1.4.



The IP extender extends the range of video signals – such as a media player or set-top box – over a Gigabit IP network. This allows image signals to be reproduced in 4K at 3840×2160 60Hz with 8bit colour depth and colour sampling of 4:2:0, or in the VGA standard at a maximum 1920×1200 60Hz.

Remote workstations connected to the extender system are controlled via USB. In Addition to the audio signal embedded in HDMI, there are two further audio channels (one audio output from the source and one for connecting to a microphone on the opposite side) as well as an optical SPDIF port on the receiver to connect a digital audio device or audio amplifier.

A video wall can also be deployed on the same private network using a dedicated Gigabit Ethernet Switch. It is also possible to set up a video wall with multicast transmission system over a VPN or a dedicated Gigabit Ethernet Switch. The latter requires 8 KB jumbo frames and IGMP snooping support.



4K AV content, USB and audio can be distributed from the source device to any location in the building, or even – in one-to-many mode – to up to 256 receivers per transmitter and up to 16 transmitters per network. In combination with dedicated Gigabit switches, which are connected to each other via fibre optics, for example, AV content can be distributed within the building and even across entire company premises – including power supply via PoE.
