HDMI stands for “High Definition Multimedia Interface.” It is an all-digital connector that carries high-definition video data and up to eight digital audio channels all in one cable.
HDMI is the next-generation of digital video interface (DVI) cable, on which HDMI is based. A DVI cable only carries digital video data – as opposed to both the audio and video carried by HDMI.
The main application of this fancy all-in-one HDMI standard is the use of a single audiovisual (AV) hookup instead of two or three cables when connecting an AV source such as a DVD player to an AV receiver and/or flat-panel (digital) television.
Before buying an HDMI cable here are a few good things to know:
- For an emerging and advanced technology these cables are surprisingly accessible – you can get HDMI cables for as low as $7.98. Longer cables are more costly.
- HDMI cables and ports are delicate and easily damaged – so plug with care.
- For your home theater setup, one HDMI cable will replace a lot of pesky cable clutter.
- You can also use one to connect your PC to your digital television for multimedia viewing.
- The data transferred on an HDMI cable is uncompressed resulting in no signal degradation.
- HDMI cables are backwards compatible with their predecessor, DVI cables.
- The latest version 1.4 cables support 3-D, are equipped with an Ethernet channel and increase the supported resolution
- Most cables come with a one-year warranty.
You will find HDMI ports on the following hardware:
- Televisions
- Cable/satellite boxes
- Game consoles
- A/V receivers
- DVD/CD players
- Media PCs
- Projectors
- Displays
- Camcorders
HDMI cables support every video and audio format in the consumer electronics industry:
- Dolby Digital
- DTS, DTS-EX
- DVD Audio
- SACD
- Dolby TrueHD
- DTS-HD Master Audio
When you do a little reading and really find out what these cables can do, you realize the sheer amount of raw data being pushed through this specialized wire. This is not your dad’s coax cable!
One of the nicest benefits to HDMI, besides picture and audio quality, is the simple fact that an HDMI cable can push HD video, full theater audio, data and control information, all at the same time, and at an astonishingly high speed.
If you’re an audiophile, or even a casual movie nut, you should have a blissful smile on your face with the introduction of this cable into your system. Your significant other will be pleased with the noticeable reduction in clutter around your setup, too.
