Silex Insight launches the all-new VIPER (4K60 4:4:4 AV over IP transmitter/receiver board), ideal for collaboration featuring seamless switching between multiple inputs (2xHDMI/1xUSB-C)

Silex Insight, a leading provider of video codec and AV over IP solutions has today announced the next generation of AV over IP 4K60 4:4:4 board, delivering the ultimate combination of inputs, highest quality, and features. It comes with an all-new design with 3 inputs for seamless switching between the sources for optimal collaboration. At the heart of the new VIPER is the Colibri video codec that perfectly encode any graphical content while preserving a visually lossless quality for video. Together it is the most powerful transmitter/receiver system, including features such as zero latency and multiview.

The VIPER board targets integrators and equipment manufacturers willing to develop their own HDMI/USB-C over IP products with reduced investment and time-to-market. This innovative board is designed for seamless integration into applications such as video conferencing, health care, command & control, residential AV distribution, digital signage, video walls and multiview.


This all-new board transport HDMI/USB-C signals up to 4K/UHD resolution with embedded audio. At the flick of a switch the VIPER board can be adjusted to meet the desired speed (1GbE, 2.5GbE and 10GbE) requested by the customer. The latency is extremely low and totally imperceptible. The networking capabilities of VIPER are very complete with the support of unicast/multicast AV streaming, encryption, forward-error-correction, and remote configuration and upgrade.


The VIPER board is equipped with two HDMI inputs, as well as a USB-C input. The two HDMI inputs support any 4K HDMI signals, while the USB-C input allows users to share directly a 4K monitor, keyboard, mouse, docucam, webcam as well as other USB-C accessories. In addition, it supports Macs, PCs, tablets and phones having USB-C connectors. The control over which input is used (and the switching policy) can easily be done in the VIPER web interface or control management using the available API.

The Professional Audio/Video market moves rapidly to IP. The majority of the codecs developed for the ProAV industry, are focused on optimizing the video content (such as JPEG 2000 and JPEG XS). However, it has shown that they cannot preserve a high quality on complex graphical content needed for the main Pro-AV use case: 4K60 over 1GbE. This is why Silex Insight has developed the Colibri codec, to fill this gap. It is optimized to encode perfectly any graphical content while preserving a visually lossless quality for video/moving images. Colibri combines numerous advantages into a single video codec, including 100% image quality, zero latency, exceptional flexibility and multiviewfunctionality, such as picture-in-picture and quadrant view. The Colibri video codec is now available with the all-new VIPER board. For more information about the Colibri video codec:
