Gefen is now shipping its two new 4K Video Over IP products. The Sender and Receiver KVM units (the EXT-UHDV-KA-LANS-TX and EXT-UHDV-KA-LANS-RX) join the existing Gefen Video Over IP products and add 4K support, a built-in scaler, videowall capability, Power-over-Ethernet, and digital/analogue audio break-out.

The new products can transmit 4K video content up to 3840×2160 at 60Hz and 4:2:0 Chroma subsampling. This new pair utilises an effective compression codec to ensure that the most popular formats for today’s 4K sources are supported, while also retaining the ability of Gefen’s current generation to exist on the most commonly deployed Gigabit network infrastructures. Both products support HDMI input resolutions up to 4K 60Hz 4:2:0 and output resolutions up to 4K 30Hz 4:4:4, HDCP 2.2 and 1.4, and 7.1 channels of HBR (High Bit Rate) lossless and LPCM digital audio up to 330 feet.

The new Gefen Video Over IP products also include new videowall control functionality. “Gefen’s new 4K-capable Video Over IP products provide an easy and cost-effective alternative to creating customised videowalls in any combination up to a 16×16 display array,” Gefen Product Manager Jason Fitzgerald said. “Bezel compensation, internal timing synchronisation, and built-in scaling functions guarantee precise and effective videowall deployments.”

Additionally, both the Sender and Receiver units support the concurrent connection of a VGA and HDMI device. The Sender acts as a switcher, allowing the user to select either the analogue VGA input or digital HDMI input as a source for the video over IP network. A local VGA output is also available to monitor either selected signal. On the Receiver, the VGA and HDMI outputs are both active and function as a video splitter, providing analogue and digital outputs for nearly any display present. The VGA input and output support VESA resolutions up to 1920×1200 at 60Hz (WUXGA). This product also provides RS-232 and two-way IR routing between the Sender and the Receiver units, allowing the transfer of IR commands and RS-232 communications among all sources and the displays. Both products can also take advantage of Power-over-Ethernet (PoE) to simplify installation.

In addition to the current generation’s analogue audio output capabilities, the new products feature an optical digital output. The new digital and analogue audio break-out feature allows the audio from the HDMI output to be sent to a separate audio system, enhancing the experience in any venue. The Receiver’s four USB outputs accommodate touch panels, keyboards and mice, and a variety of other supported devices.

The cable run from a Sender to a Receiver can be up to 100m. The Receiver features a built-in Gigabit switch, allowing the connection of additional receivers to provide daisy-chaining functionality. In applications such as digital signage, where there may be a need to replicate content on multiple displays throughout an installation, the ability to cascade receivers removes the requirement for additional cables to be connected directly to the main network switch, thereby optimising cable runs and extending the range of these units far beyond the limits of a point-to-point video distribution system.
