HDMI HDBaseT extender kits can be bi-directional
Key Digital’s KD-X444S and KD-X444L 18Gbits per second HDBaseT HDMI extender sets are for standard (4K/40m and 1080P/70m) in the case of the KD-X444S and for long range distances (4K/70m and 1080P/100m) for the KD-X444L (pictured).
In addition to HDMI, IR and RS-232 signals may be simultaneously and bi-directionally extended over independent connectors. The LED set, extended display identification data (EDID) and control rotaries integration tools are included.
Key Digital believes the KD-X444S and KD-X444L are some of the first extenders capable of outputting 18Gbits per second from a 4K source and also commanding displays to receive that signal in 18Gbits per second. Compression at Tx enables the signal to be sent as 10G instead of 18Gbits per second and then decompressed at the Rx unit back into full 18Gbits per second signal.
Key Digital engineers worked to take this new technology and improve on it until even 10G signals would be compressed. As a result of their ingenuity, Key Digital says, the KD-X444S and KD-X444L includes 10G pass-through mode which enables incoming signals with 10.2Gbits per second bandwidth or less to be extended without being subjected to the standard CSA or VLC compressions.
Both extender sets feature a low profile, slim chassis design. Key Digital’s KD-SMS16 universal rack mount shelf is a perfect option for these extenders and other smaller Key Digital items.
KD-X444L and KD-X444S carry IR and RS-232 for controlling remotely located equipment. IR sensor powering via +5V on IR in ports collects line-of-sight IR from remote(s) without external IR connecting block. Two channels of IR and bi-directional RS-232 enable control to/from devices or control systems connected to Tx and Rx units. CEC Pass-through for inter-device control between input and output HDMI channels is also supported.
Both extender sets have compliancy up to HDCP 2.2 and are backwards-compliant and feature high dynamic range (HDR10). Key Digital’s HDR10 delivery is handled as part of the proprietary Full-Buffer Technology which manages TMDS re-clocking / signal re-generation, HDCP authentication with source and display, EDID control handshake and hot plug detection control on both the source and display. Integrators have the choice of handshake delivered to the connected video source.
Key Digital’s internal library has 16 EDID handshakes including an update to 4K handshakes with HDR header information. Additionally, the native EDID data from the connected output/display device may be provided to the video source.
The EDID and control dial on the units are useful for integrators in the field to tell their connected source the exact video and audio formatting needed by simply turning the rotary, rather than having to go into the setup menus of the connected source devices when HDR was not part of that handshake.
The KD-X444L and the KD-X444S use HDBaseT via single CAT5e/6 UTP/STP extension with fully automatic adjustment of feedback, equalisation, and amplification depending on cabling length. The extender sets offer UHD/4K support 4096×2160 or 3840×2160 24/25/30/60hz at 4:4:4 with signals up to 18Gbits per second bandwidth and offer flexible power over HDBaseT with only one power connection needed with the Tx providing power to the Rx, or the Rx powering the Tx.
