An Introduction to HDMI
HDMI – the new kid on the block!!
This new connector, which we will start seeing in 2005, bases itself on the DVI-HDCP connection. (see HDCP)
DVI comes from the computer world, HDMI was designed as a home theatre connection and all of the industry leaders have agreed on its specifications.
HDMI adds the ability to carry not only digital video but also digital audio within a single cable. HDMI’s audio capability is such that it will carry the compressed multi channel; digital formats we all know, such as Dolby Digital and DTS “Digital Surround” but can also carry up to eight channels of uncompressed digital audio.
| HDMI supports: |
Every uncompressed standard, enhanced and high definition formats ranging from 480I to 480P, 720P, 1080I & 1080Pn as well as existing PAL formats.Compressed and uncompressed audio formats. Most standard PC formats, such as VGA, XGA and SXGA. |
ALL this in ONE Cable.
Using a smaller connector that eliminates the need for multiple cables in home entertainment systems, simplifying installation and eliminating cross technology confusion – no wonder, with all these advantages HDMI is expected to become the digital interface for consumer home theatre products & computer systems. Consumers are likely to see HDMI connectors on new electronic devices for many years to come. However, don’t throw away your old video cables just yet, but keep an eye out for DVI & HDMI in the future.
Good News
HDMI is compatible with DVI, you will only need an DVI – to – HDMI Adaptor (LINK). Of course you will not get Audio when you convert HDMI to DVI, but that is not a problem since you can always carry the Audio by using separate cables.
So there is no need to put off a purchase because the device only has DVI.
Remember
HDMI also carries the HDCP protocol (copy protection) – See What is HDCP & DVI-HDTV? |
