HDMI or High Definition Multimedia Interface technology has changed the way we watch television forever. It is an interface provided by the HDMI cable for transmission of high quality audiovisual signals. In the past, cables used to convert the digital signal into analogue which would always result in loss of signal quality. But HDMI brings you crystal clear audio and video directly from the source.
How does HDMI work?
An HDMI cable has 19 enclosed wires inside it. It can transmit digital data at speeds in excess of 10.3 gigabytes per second, which is twice the bandwidth than what is required. HDMI cables can also accommodate up to 8 audio channels at one time. They have the capacity to transmit digital data directly from source to your HD (High Definition) television screen. The technology was introduced in the year 2002 and has undergone many upgrades since then. The popular HDMI upgrades you may have come across are HDMI 1.0, HDMI 1.1, HDMI 1.2, HDMI 1.2a, HDMI 1.3 and the latest upgrade being HDMI 1.4.
What does HDMI 1.4 offer?
HDMI 1.4 enables internet use through Ethernet connectivity without using another separate cable. Upstream audio transmission for playback has also been enabled by the new Audio Return channel. HDMI 1.4 has been optimised for all types of 3D formats. It can standardise the input/ output ratio of the 3D device and bring it out at a dual flow channel 1080p resolution. The HDMI technology is backward accommodating which means that you can connect a slightly older HD device to the latest HDMI 1.4 cable and still get quality transmission.
