HDMI Extender Kit Delivers 18 Gb/s Via Cat5e/6

Key Digital’s KD-X444S extender kit provides HDMI signal extension up to 18 Gbps via a single CAT5e/6 cable/interface. The HDCP2.2 compliant KD-X444S HDBaseT Tx and Rx kit sports a low-profile chassis and supports all the latest HDMI standards.

 

The kit features support of HDR10 (High Dynamic Range) video, which allows users to experience more life-like images through a greater range of luminance levels. Key Digital’s HDR10 delivery is handled as part of their proprietary Full-Buffer Technology (FBT). Studies have concluded that viewers prefer video signals with more contrast ratio vs higher resolution. This extender set delivers the highest possible support across both highly sought-after features. Also, a 10G pass-thru mode enables uncompressed 10.2Gbps signal extension.

Fierce AI Week

Register today for Fierce AI Week - a free virtual event | August 10-12

Advances in AI and Machine Learning are adding an unprecedented level of intelligence to everything through capabilities such as speech processing and image & facial recognition. An essential event for design engineers and AI professionals, Engineering AI sessions during Fierce AI Week explore some of the most innovative real-world applications today, the technological advances that are accelerating adoption of AI and Machine Learning, and what the future holds for this game-changing technology.

 

KD-X444S extends UHD / 4K (4096x2160 / 3840x2160 24/25/30/60hz) resolutions at 4:4:4 with bandwidth up to 18 Gbps and audio formats up to Dolby TrueHD, Dolby Digital Plus, Dolby Atmos, and DTS-HD Master audio up to 40m (130 ft) using CAT5e/6 cabling. 1080p resolution is extended up to 70m (230 ft) with CAT6 cabling.

 

Other features include automatic adjustment of feedback, equalization, and amplification depending on cabling length, so integrators no longer need to fine tune equalization knobs for each display. The extender set features flexible power over HDBaseT with only one power connection needed with the Tx providing power to the Rx or the Rx powering the Tx.

 

Full Buffer System manages TMDS re-clocking, signal re-generation, HDCP authentication with source and display, EDID Control handshake, and Hot Plug Detection control. Integrators have the choice of handshake delivered to the connected video source. Key Digital boasts an internal library with 15 EDID handshakes including an update to 4K handshakes which includes HDR Header information. Additionally, the native EDID data from the connected Output/Display device may be provided to the video source.

 

In addition to HDMI video and audio signals, KD-X444S carries 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-thru for inter-device control between input and output HDMI channels is also supported. For more information, peruse the KD-X444S datasheet.
