HDMI Connection
HDMI is the acronym for High-Definition Multimedia Interface. HDMI cable, like DVI, is dedicated to transferring digital signals. However, HDMI is capable of sending audio information while DVI is dedicated to transferring only digital video. This is another popular format for digital information transfer between home theater components, especially with the falling prices of high-definition televisions (HDTV).
Why HDMI Cable?
HDMI allows digital information, both audio and video, to be transferred without the compression necessary in other formats. By circumventing the compression process, the digital signal that is received remains closer to the original. The nature of HDMI cable means that there is no need for converting digital signals to analog, thereby eliminating audio and video artifacts that are the result of multiple conversions. This means a truer signal that results in higher quality sound and video.In the area of sound, HDMI cable is capable of transferring multichannel audio. What this means for you is that rather than using multiple audio cables, all audio information is sent through a single HDMI cable. Less clutter for you.
This type of cable is also compatible with all HDTV formats such as 720p and 1080i. Since HDMI cable sends both digital audio and video, it eliminates the need to have separate cables for each. The HDMI cable is also able to facilitate two-way communication between home theater components.
