Silex Insight releases new video codec Colibri

Silex Colibri is designed to preserve complex graphics in AV Over IP distribution over 1GbE as an alternative to JPEG 2000 and JPEG XS

Silex Insight has developed a video codec called Colibri as a competitor to JPEG 2000 and JPEG XS. It is the smartest video codec Silex Insight has ever developed and the first one designed specifically for the AV over IP market with focus on graphical elements for distribution over 1GbE network.

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). 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

For complex graphical content, Colibri delivers crystal clear quality over 1Gb, 2.5Gb, 5Gb and 10Gb ethernet cable.

Zero Perceived Latency

The latency is invisible to the human eye, with 24 lines of video, which corresponds to 180 μs in 4K60fps.

Low complexity

It is a very lightweight codec, with low logic size and DDR bandwidth, which is ideal for applications which demand low power.


Offers a unique lightweight solution to build a multiview application with many video channels (as many simultaneous streams you need).

Colibri is unique, delivering best-in-class crystal clear graphical content for AV over IP distribution over 1GbE. It builds on more than a decade of designing video codecs and we are entering a whole new era”said Michel Van Maercke, Chief Executive Officer at Silex Insight. “Colibri covers all the requirements of the ProAV market: zero latency, high quality, support for 8K, low resources/power, and support for Multiview. It is ideal for applications such as KVM, control rooms and conferencing.”

In addition to the Colibri video codec, Silex Insight also offers a add-on option of a 4K60fps AV over IP transmitter and receiver solution, called VIPER. It is perfectly suited for the Colibri video codec, supporting multiview and zero latency audio/video over IP. It features high resolutions up to 4K/UHD over 1Gb, 2.5Gb or 10Gb Ethernet cable and is available for shipping now.
