Introducing HDMI 1.4
The HDMI standard just got a lot more powerful, with new capabilities designed to push the boundaries of the HD experience – both in the home and on the go.
Here are the major enhancements introduced in the HDMI 1.4 specification:
· 
HDMI Ethernet Channel– Adds high-speed networking to an HDMI link, allowing users to take full advantage of their IP-enabled devices without a separate Ethernet cable.
· Audio Return Channel– Allows an HDMI-connected TV with a built-in tuner to send audio data "upstream" to a surround audio system, eliminating the need for a separate audio cable.
· 
3D– Defines input/output protocols for major 3D video formats, paving the way for true 3D gaming and 3D home theater applications.
· 4K Support– Enables video resolutions far beyond 1080p, supporting next-generation displays that will rival the Digital Cinema systems used in many commercial movie theatres.
· 
Content Type– Real-time signaling of content types between display and source devices, enabling a TV to optimize picture settings based on content type
· Additional Color Spaces– Adds support for additional color models used in digital photography and computer graphics.
· HDMI Micro Connector– A new, smaller connector for phones and other portable devices, supporting video resolutions up to 1080p.
· Automotive Connection System– New cables and connectors for automotive video systems, designed to meet the unique demands of the motoring environment while delivering true HD quality.
