ATEN Real Visual Compression Technology
ATEN Real Visual technology is an advanced image compression technology that has been specially refined for
utilization in ATEN's KVM over IP Extenders. It provides the highest rate of video data integrity for resolutions up
to 4K@60Hz over a 1GB network switch and 5K@60Hz over a 10GB network switch, and provides high quality
imaging for both text and natural scenery.
ATEN Real Visual compression is one of the most effective methods of image compression. By using ATEN Real
Visual technology, the details of video in 4:4:4 color sampling can be preserved in the transmission process.
The human eye is particularly sensitive to low frequency information (also called luminance) in images, and so
because ATEN Real Visual compression boosts information in this area, effectively reducing distortion, this is
what makes it especially useful in video applications over long distances.
The ATEN Real Visual technology compression process from the local transmitter to the remote receiver has a
latency of about 1-2 frames. Compared to other kinds of compression, such as Standard H.264 that has a latency
of more than 10 frames, ATEN Real Visual compression is therefore especially useful in KVM applications where
it can mirror mouse movements with latency less than 32ms so that it does not impair the operator’s experience.
ATEN Real Visual compression also produces a higher rate of image integrity than other kinds of compression.
For example, it completely eliminates JPEG mosquito aliasing effects, and this is extremely important for word
processing or applications that require the highest video quality possible (4:4:4), such as medical imaging.
