HDMI, also known as High Definition Multimedia Interface is an advanced technology that is used for transmitting digital data between two digital devices. This technology was developed by leading electronics manufacturers like Philips, Toshiba, Hitachi, Sony etc. Ever since it was introduced, it has become quite popular. Its latest version, 2.0, was introduced in September 2013.
If you are new to HDMI Cables or HDMi adapters, and want to know more about it, take a look at some frequently asked question and their answers. These will give you more insights about HDMI cables and their working.
What is the purpose of HDMI technology?
HDMI technology is mostly utilized to transmit multichannel audio and high definition video data between two digital devices. This process of transmission takes place through a single cable. You will be able to find HDMI technology in all the latest electronic equipment including AV receivers, personal computers, set top boxes and camcorders.
How does it work?
An HDMI cable utilizes the Transition Minimized Differential Signaling (TMDS) technology for transmitting data between two digital devices. It also takes care of the fact that the data doesn’t get compromised when it gets transferred from one device to another. Due to HDMI cables, there is no need to convert data for making it compatible. And as no conversion takes place, images and videos look exactly like they should without the quality getting affected.
What Is It Compatible With?
Since HDMI is an updated version of DVI (Digital Visual Interface), it is compatible with DVI for video only. HDMI and DVI use similar digital signals. So there is no need to convert anything while connecting the two devices. Also there is no compromise with data quality when you use an adaptor. HDMI being the most dynamic technology, it will never have major issues related to compatibility.
Does HDMI have competitors?
Displayport is one of the primary competitors of HDMI technology. It is a digital display interface which was developed by Video Electronics Standard Association (VESA). It is not compatible with HDMI in anyway and also doesn’t work with any equipment supported by HDMI technology. So DisplayPort cables won’t work with HDMI equipment.
Can HDMI Cables Cope with 4K?
When you buy an HDMI cable, make sure that it is High Speed rated and has 3D and 4K internet sharing capacity. Long cables might have issues maintaining functionality under certain circumstances. This is because long cables have high electrical resistance and it lowers the available bandwidth. In case you’re using long cables, you would need high quality cables for the bandwidth to be maintained.
HDMI has become the most accepted and universal standard of connecting HD devices. It has been embraced by people because of its potential to change with evolving technologies, user-friendliness. It also offers High Bandwidth Digital Content Protection.
