The HDMI 1.4 specification adds a data channel to the HDMI connection, enabling high-speed, bi-directional communication. Connected devices that include this feature can send and receive data via 100 Mb/sec Ethernet, making them instantly ready for any IP-based application. The HDMI Ethernet Channel allows internet-enabled HDMI devices to share an internet connection via the HDMI link, with no need for a separate Ethernet cable. It also provides the connection platform that will allow HDMI-enabled components to share content between devices.

The new specification adds an audio channel that will reduce the number of cables required to deliver audio upstream from a TV to an A/V receiver for processing and playback. In cases where a TV features an internal content source, such as a built-in tuner or DVD player, the Audio Return Channel allows the TV to send audio data upstream to the A/V receiver via the HDMI cable, eliminating the need for an extra cable.

An audio channel that enables upstream audio connections via HDMI
Simplifies the audio connection between the TV and Audio/Video Receiver

Helps reduce yet another cable within the home

The 1.4 version of the specification defines common 3D formats and resolutions for HDMI-enabled devices, enabling 3D gaming and other 3D video applications. The specification standardizes the input/output portion of the home 3D system, facilitating 3D resolutions up to dual-stream 1080p.

The new specification enables HDMI devices to support extremely high HD resolutions, effectively four times the resolution of a 1080p device. Support for 4K allows the HDMI interface to transmit digital content at the same resolution as the state-of-the-art Digital Cinema systems used in many movie theaters.

HDMI Micro Connector (Type D)
In addition to the three connector types already defined in previous versions of the HDMI standard, the HDMI 1.4 specification introduces a new "Type D" connector designed for cell phones, pocket cameras, and other portable devices where space is at a premium.
Roughly the size of a Micro USB connector, it packs all the power and functionality of an HDMI link into a tiny form factor. Featuring a full nineteen-pin array like other HDMI connectors, the HDMI Micro Connector can handle video signals up to 1080p, bringing state-of-the-art HD resolutions to the realm of handheld devices.
This new connector is approximately 50% smaller than the size of the existing HDMI Mini Connector.
Automotive Connection System (Type E)
The Automotive Connection System is a cabling specification designed to be used for in-vehicle HD content distribution. The HDMI 1.4 specification provides a solution designed to meet the rigors and environmental issues commonly found in automobiles, such as heat, vibration and noise. Using the Automotive Connection System, car manufacturers now have a viable solution for HD distribution within a vehicle.
