This newly announced HDMI 1.4 establishes protocols for several 3D display technologies including frame, line, or field alternative methods; side by side display, and 2D plus depth methods. The new specification also features data as an essential feature, with a dedicated pipe for 100Mbps Ethernet connections. An Audio Return Channel is designed to send compressed sound through intermediary devices, while a proposed micro HDMI connector will support 1080p video for small devices.
