Compared with DVI can transmit digital audio signal, and an increase in support for HDPC, at the same time provides better DDC optional features.
support 5 GBPS data transfer rate, can transmit far 15 meters, enough to cope with a 1080 p video and an 8 channel audio signal. And because a 1080 p video and an 8 channel audio signal needs less than 4 gb/s, therefore also has the very big margin .
