HDMI (High-Definition Multimedia Interface) represents a remarkable advancement in home cinema cable technology. It offers a high quality multimedia experience when connected to video or audio sources such as HDTVs, Blu-ray players and gaming consoles like the PlayStation 3 and the Xbox 360.
The specification of HDMI 1.4 surpasses earlier versions with advancements in areas like automotive connection system, resolution improvement and network capability.
New features of HDMI 1.4
Audio return channel
HDMI 1.4 offers a new audio return channel that minimises the number of required cables. It also ensures that the HDTV is able to send audio stream to the visual/audio receiver using an HDMI cable.
HDMI Ethernet channel
The HDMI 1.4 offers an improvement in bi-directional communication speed. In addition to this, the data channel also makes devices ready for Internet Protocol based applications. Another important advantage of the HDMI Ethernet channel is that it allows the ability to share internet connection with other HDMI devices without having to use separate cables.
Resolution for 3D
Using older HDMI versions, people face problems in playing different 3D formats on their existing 3D home cinema systems. However, in the case of HDMI 1.4, the problem is taken care of by standardising the input/output portion of your system. At the same time, resolution is also defined to allow your high-definition devices to play files with dual streams and resolutions of up to 1080p.
