HDMI means a simpler and higher-quality entertainment experience. It provides the highest possible uncompressed video and audio quality over a thin, easy-to-use cable with a simple, consumer-friendly connector. It’s also backwards compatible with DVI, requiring only a simple passive adaptor or cable to connect between the two interfaces.
Most importantly, it adds support for up to 8 channels of full-resolution digital audio, all on a single cable. HDMI has the ability to transmit basic control codes from device to device, making the goal of system integration easier to achieve.
HDMI addresses the complexity issue by both reducing the cable count and easing the process of interconnecting the various devices that make up the typical home entertainment system. Instead of having to choose among RF, composite video, S-video and component video and optical digital audio or coax-based digital audio, everything can use a single HDMI connection. For example, in the case of a DVD Audio or SACD Audio capable DVD player, a single HDMI cable can replace up to 10 other connections (3 for analog component video, 1 for optical or coax digital audio and 6 for the 5.1 multichannel analog audio outputs).
Added to this is the ability to simultaneously achieve the best possible audio and video quality due to the uncompressed all digital signaling of HDMI.
The most recent version of HDMI, more than doubles the bandwidth of the signaling from 4.95 gigabits per second to 10.2 gigabits per second. This increase in bandwidth enables greater color depths, higher screen resolutions and faster refresh rates. It supports the new xvYCC color space, adds support for the Dolby ® TrueHD and DTS-HD Master Audio standards, provides a mini-connector for use with camcorders and digital still cameras, and supports the ability to automatically and accurately adjust the audio to maintain lipsync with the video image.
Quality:
Because HDMI is a digital interface, it provides the best quality video since there are no lossy analog to digital conversions that are required for analogue connections (such as component or S-video). The difference is especially noticeable at higher resolutions such as 1080p. Digital video will be sharper than component, and eliminates the softness and ghosting found with composite. Small, high contrast details such as text bring this difference out the most.
Ease-of-use:
HDMI combines video and multi-channel audio into a single cable, eliminating the cost, complexity, and confusion of multiple cables currently used in A/V systems. This is particularly beneficial when equipment is being upgraded or added.
Intelligence:
HDMI supports two-way communication between the video source (such as a DVD player) and the DTV, enabling new functionality such as automatic configuration and one-touch play. By using HDMI, devices automatically deliver the most effective format (e.g. 480p vs. 720p, 16:9 vs. 4:3) for the display that it is connected – eliminating the need for the consumer to scroll through all the format options guessing what will look best.
HD Content-Ready:
HDMI devices supporting HDCP (copy protection) will have access to premium HD content now and in the future.
