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 originality of the audiovisual signal intact and transmits it to our television screen without conversion or 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 capacity for networking and ethernet connectivity. HDMI 1.4 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. Mentioned below are some of the features supported by HDMI cables.
High Definition Ethernet connectivity
This upgrade offers high speed bi-directional transmission. Data is transferred at speeds in excess of 100 megabytes per second. Internet protocol based applications can 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 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.
