Ethereal Sets Standards for HDMI Cable Testing

HOLLY HILL, FL, NOVEMBER 8, 2006: Because HDMI is the de facto standard digital interface for HD and the consumer electronics market, Ethereal Home Theater has made the commitment for its HDMI cables to meet the highest standards in the industry.

Ethereal sends every HDMI cable in every series for HDMI Certification, which is granted by HDMI Licensing, LLC, the agent responsible for licensing the High-Definition Multimedia Interface (HDMI) specification. Ethereal has submitted all 15 of its HDMI SKUs, which range in length from one to 30 meters.

“Some manufacturers send the shortest cable for certification, then base their claim of HDMI Certification upon that,” said Brent McCall, Ethereal Product Manager. “Ethereal sends out all HDMI products for certification. This makes it easier for consumers to know that they are buying a cable that has been tested and meets the standards.”

The construction of HDMI cable makes quality an important issue — especially at lengths of more than 15 feet. Of the 19 different wires in HDMI cable, the most critical are the four twisted pairs. The intra and inter pair skew with these wires can make or break high-speed data communication. As the cable gets longer, a design that functioned satisfactorily at two or four meters can easily fail as the cable gets longer or as the resolution increases. This loss in performance can manifests itself as “sparkles” or other visual artifacts in the video image.

“In an HDMI cable, there is not the same amount of data being sent at the same time,” said McCall. “The data requirements are much greater as the resolution begins to increase. Huge amounts of data are constantly traveling between the HDMI source and the sink (display) within fractions of a second. A very good quality cable makes sure that all the data goes where and when it’s supposed to go without resulting in jitter.”

In addition, Ethereal tests each cable at its state-of-the-art factory. Every cable that comes off the assembly line is put through five different tests to ensure top performance — with the final test being an actual hookup between a video source and a display. Bench tests involve bandwidth — specifically the ability to hit and sustain speed, and handling multiple data streams simultaneously.

According to McCall, the increased time the testing requires pays off in both excellent performance for the consumer’s home theater system and a “practically non-existent defect rate. We don’t get product back because of poor performance.”
