HDMI 1.4 to Support 3D TV

HDMI Licensing, the consortium that formulates the HDMI specifications, has recently announced that the new HDMI version 1.4 will support 3D content.  HDMI 1.4 supports a maximum resolution of 4K × 2K (3840×2160p and 4096×2160p); an HDMI Ethernet Channel for 100 Mbps connection between connected HDMI devices; an Audio Return Channel; a new Micro HDMI Connector; and an Automotive Connection System.  The new HDMI version will also include specifications for a number of 3D display technologies such as the frame, field or alternative line methods; 2D plus depth methods; and side by side display schemes.  The HDMI consortium is scheduled to meet in January to discuss the “Top/Bottom” 3D format.  This scheme will sacrifice resolution but will save bandwidth by shoving the left and right images into single frames.  With the broadcast industry pushing forward its plans to bring 3D TV to the home by 2010, the introduction of HDMI 1.4 is a timely development.  This will ensure compatibility between 3D source and display devices, once they become available.
