| Harness the power of Ethernet for HDMI Distribution A single Cat 5e/6 cable transmits full 1080p video and 2-channel PCM audio to multiple TVs. The HD-IP system offers reliability and excellent video quality at a great price point.  |

| The Technology Standard HDMI® devices transmit video and audio using a signaling method called TMDS (Transition Minimized Differential Signaling). TMDS was designed for short cable runs, like those necessary to connect a cable box to an HDTV in an entertainment center. Unfortunately, TMDS has some limitations. Very high frequencey signals like HDMI tend to "roll off" as cable runs get longer, ultimately reaching a point of failure when the destination device can no longer resolve the picture and audio data. Since differential pairs are used for each of the three color channels and the separate clock channel, differences in individual wire lengths inside HDMI cables can cause timing errors and blank screens. HD-IP™ technology taps into the benefits of Ethernet standards to overcome the inherent limitations of TMDS. Enabling totally reliable cable runs up to 250 feet long, easy splitting and distribution of signals, and robust signal integrity, Transmitting HDMI over IP networks redefines the possibilities for HDMI video distribution. Compliant with HDCP 2.0 specifications, this technology supports copy protection with 128-bit AES encryption and overcomes traditional key verification limitations, enabling very large system sizes while maintaining full HDCP compliance. And unlike first-generation Megabit implementations of IP technology, Audio Authority's Gigabit infrastructure means picture quality that is virtually indistinguishable from the source, suitable for the most discerning viewer. Conclusion: HD-IP™ technology is ideal for HDMI signal extension and distribution. |
