Lossless coding for transmission of high-resolution image data

August 07, 2015 // By Graham Prophet
IHSE and Fraunhofer-Institute for Integrated Circuits IIS have collaborated to implement an innovative lightweight coding technology (LICI). The codec, developed by Fraunhofer, adapts image data streams to the available communication infrastructure and bandwidth without high image resolution or dynamic range enhancements being degraded.

The LICI codec allows image-by-image, lossless transmission of high-resolution images. It also features extremely low latency, high throughput and the ability to perform bit-rate adjustment to the available bandwidth at very low latency. LICI is a suitable coding technology for image processing and transmission systems used in professional production and multimedia applications. For broadcasters, who rely on artefact-free, low-latency images, LICI delivers the best possible solution today, the collaborators assert.

IHSE has worked in partnership with Fraunhofer to develop the first ever implementation in keyboard/video/mouse (KVM) technology. The Fraunhofer LICI codec is embedded in IHSE's next generation KVM extender technology supporting DisplayPort signals up to 4K resolution and beyond.

"Professional KVM technology for multiple monitor management is driven by the demands of visually lossless image data transfer over existing infrastructure cabling or limited bandwidth without latency," said Enno Littmann, managing director of IHSE GmbH. "We chose Fraunhofer IIS as our development partner for image coding to give us the ability to offer new products that meet these market requirements."

IHSE is a developer and manufacturer of advanced Keyboard, Video, Mouse (KVM) devices with 30 years of experience. KVM technology enables the remote switching, bidirectional extension and conversion of primary computer signals including DVI, HDMI, 4K DisplayPort, digital audio and USB. IHSE develops and manufactures KVM switches and extenders with visually lossless signal transmission at its headquarters near Lake Constance, Germany.
