The High Definition Multimedia Interface (HDMI) has revolutionised the way we watch video and listen to music. It is the only technology of its kind that keeps the clarity of the audiovisual signal intact and transmits it to our television screens without data loss. The result is crystal clear audiovisuals for an exhilarating viewing experience.
HDMI 1.4 is the latest version of the technology. It offers several developments over its predecessors. The latest upgrade of the technology offers higher networking capacity such as Ethernet connectivity. HDMI 1.4 also enables upstream audio transmission along the HDMI cable by the new Audio Return channel.
HDMI 1.4 has taken connectivity to a whole new level. Let’s see what new things it supports.
High Definition Ethernet connectivity
This upgrade offers high speed bi-directional transmission. Data transmission is done at speeds in excess of 100 megabytes per second. Internet protocol based applications can also be instantaneously operational. This feature also allows internet sharing with other computers without the need of an extra cable.
High Definition Audio Return channel
HDMI 1.4 has reduced the number of cables required for upstream transmission of audio and playback. HD televisions can now send the audio stream to a receiver through the HDMI cable for direct reception of audiovisual signals.
High Definition 3D support
HDMI 1.4 identifies all the common 3D formats and resolution levels for every HD device. This version of the technology standardises the input to output ratio of the 3D system and renders it at dual flow 1080p resolution.
