When the HDMI format was introduced many years ago it was originally designed for the transmission of digital A/V signals over short distances. Through the years cable and connectivity product manufacturers have worked diligently to increase the capabilities of the HDMI format as the protocol has changed and matured.

The New York-based manufacturer Key Digital has been at the forefront of HDMI product technology development through its vast line of matrix switchers, cables, video processors and other solutions. Recently the company added to its selection of signal transmission solutions when it announced its KD-CATHD500 balun that it says is designed to transmit the latest audio and video signals hundreds of feet. The KD-CATHD500 is a copyright friendly, HDCP compliant device that works with 3D video content, as well as 4K video and commercial video resolutions such as 1900x1200. Bolstering the unit’s safe and reliable operation is its ability to store 10 internal EDID configurations, including the native EDID information of any input and output product. Highlighting the product’s signal transmission capabilities is the KD-CATHD500’s ability to send and receive 1080p/60fps video as far as 400 feet, and its ability to transmit and receive 1080i/60fps from as far away as 600 feet.

Key Digital also explains the balun supports the transmission and reception of IR, RS-232 and CEC control signals, and other A/V HDMI protocols such as the 12-bit Deep Color property and the Dolby TrueHD and DTS HD Master Audio surround sound formats.
