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 Digital agency UK 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 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.
