New HDMI 1.4 Specifications Unveiled
Lets take a peek at the specifications.
It is official now as HDMI 1.4 specifications are announced in a press release, offering a slew of improvements with a brand new touch.
The following are enhancements that will be brought to the new specification.
HDMI Ethernet Channel
a data channel to the HDMI cable and will enable high-speed
bi-directional communication. Connected devices that include this
feature will be able to send and receive data via 100 Mb/sec Ethernet.
Audio Return Channel
An Audio Return Channel will reduce the number of cables required to
deliver audio upstream for processing and playback. In cases where
HDTVs are directly receiving audio and video content, this new Audio
Return Channel allows the HDTV to send the audio stream to the A/V
receiver over the HDMI cable, eliminating the need for an extra cable.
3D Over HDMI
1.4 version of the specification will define common 3D formats and
resolutions for HDMI-enabled devices. The specification will
standardize the input/output portion of the home 3D system and will
specify up to dual-stream 1080p resolution.
New Resolutions Supported
- 3840×2160 24Hz/25Hz/30Hz
- 4096×2160 24Hz
Micro HDMI Connector
The Micro HDMI Connector is a
significantly smaller 19-pin connector that supports up to 1080p
resolutions for portable devices. This new connector is approximately
50% smaller than the size of the existing HDMI Mini Connector.
Automotive Connection System
Designed to be used as the basis for in-vehicle
HD content distribution. It is designed to meet the rigors and environmental issues commonly
found in automobiles, such as heat, vibration and noise.
- Standard HDMI Cable – supports data rates up to 1080i/60;
- High Speed HDMI Cable – supports data rates beyond 1080p, including Deep Color and all 3D formats of the new 1.4 specification;

HDMI 1.5, anyone ?
