subject: Hdmi 1.4 Enhanced Features And Functionalities For Digital Connectivity [print this page] HDMI 1.4 is the new specification for HDMI, the acronym for High-Definition Multimedia Interface (HDMI). Like previous versions of the specification, HDMI Licensing, LLC is the licensing body for this new specification version HDMI 1.4. An HDMI cable - that has implemented earlier versions of the specification is used for high quality multimedia experience while connecting audio and video sources like HDTVs.
For further improvement in the multimedia experience, the new HDMI 1.4 specification implements several advancements in areas such as Network Capability, Resolution Improvement and Automotive Connection System. You can download the HDMI 1.4 specification from the HDMI Licensing, LLC. website.
Let's take a look at the some of the changes, including advancements that HDMI 1.4 brings to your multimedia experience in the near future:
HDMI Ethernet Channel
HDMI 1.4 plans to append a data channel to the pre-existing HDMI cable. This ensures an increase in bi-directional communication speed. Moreover, this additional data channel would make the devices immediately ready for IP-based applications. Another significant advantage that HDMI Ethernet channel delivers is its capability to share an internet connection with any other HDMI device without the use of a separate cable.
Audio Return Channel
HDMI 1.4 provides a new Audio Return channel. This Audio Return Channel reduces the number of cables that are required and yet ensures that HDTV can send an audio stream to an Audio/Visual receiver through the cordon hdmi cable.
Common Format and Resolution for 3D
If there is a problem in playing different 3D formats on a 3D home theatre system, this 1.4 version takes care of the problem by standardizing the I/O portion of your system. At the same time, the resolution is defined in such a way that your high-definition devices can play files having dual stream and that have resolutions up to 1080p. Thus, you get a common format and resolution for all 3D files that your HDMI-enabled devices can play.
Support for Higher Resolutions
A user can also play files with higher resolutions, up to 4k x 2k, using this specification. It enables every HDMI device to provide the required support, which will help in transmitting content at a resolution similar to the ones used in most digital theaters.
Reproduction of Accurate Colors for Digital Still Camera Images
HDMI 1.4 specification also supports color spaces. It allows HDMI enabled devices to reproduce accurate colors of images taken through a digital still camera on different applications including Adobe RGB, AdobeYCC601 and sYCC601.
Micro HDMI Connector: Smaller Size, More Features
The Micro HDMI Connector is not only smaller in size than the existing version currently used in HDMI devices - but it also provides support for high resolutions (up to 1080p) that can play on most portable devices.
Automotive Connection System
Automobile manufacturers face problems in HD content distribution, mainly due to the presence of environment issues that include heat, noise and vibration. HDMI 1.4 has provided a solution to these problems in the form of an automotive connection system. This feature has been designed for high-quality in-vehicle HD-Content distribution.
HDMI 1.4 is the new way of defining digital connectivity and is targeted for both consumer electronic gadgets as well as PCs, in the near future.
