Is HDMI Finally Ready?
Les Chard, president of HDMI Licensing LLC, said one of the key factors in resolving HDMI interoperability issues was the release of the HDCP test specification and requirement for HDCP testing. HDCP accounted for the majority of HDMI interoperability problems reported in the initial versions of products, he said.
HDCP testing is now available, and was required for every HDMI product in Compliance Test Specification (CTS) 1.3a, released last November, Chard said. “This has gone a long way to eliminating HDMI interoperability problems,” Chard said. “The biggest HDCP-related problem was in (cable) set-top boxes (STBs) from a number of vendors. While the correction was a trivial firmware fix, the problem was that the cable and satellite companies had to download this updated firmware to their installed STBs.”
Finally, HDMI Licensing LLC is working on problems with the HDMI connector design itself to prevent the cables from popping off components and displays. Companies such as Gefen and others have developed “locking” HDMI cable options. Monster Cable at CEDIA Expo will introduce longer-length, thinner high performance HDMI cable designed to create less pull on the cable plug itself.
