3.1 About HDMI—General Description
High-Definition Multimedia Interface (HDMI) is an uncompressed all-digital audio/video
interface, widely supported in the entertainment and home cinema industry. HDMI
ensures an all-digital rendering of video without the losses associated with analog
interfaces and their unnecessary digital-to-analog conversions. It delivers the maximum
high-definition image and sound quality in use today. Note that Kramer Electronics

In particular, HDMI:
• Provides a simple interface between any audio/video source, such as a set-
top box, DVD player, or A/V receiver and video monitor, such as a digital flat
LCD / plasma television (DTV), over a single lengthy cable
SIMPLICITY - With video and multi-channel audio combined into a single cable, the
cost, complexity, and confusion of multiple cables currently used in A/V systems is
reduced
LENGTHY CABLE - HDMI technology has been designed to use standard copper cable
construction at up to 15m
• Supports standard, enhanced, high-definition video, and multi-channel digital
audio on a single cable
MULTI-CHANNEL DIGITAL AUDIO - HDMI supports multiple audio formats, from
standard stereo to multi-channel surround-sound. HDMI has the capacity to support
Dolby 5.1 audio and high-resolution audio formats
• Transmits all ATSC HDTV standards and supports 8-channel digital audio,
with bandwidth to spare to accommodate future enhancements and
requirements
• Benefits consumers by providing superior, uncompressed digital video quality
via a single cable, and user-friendly connector
HDMI provides the quality and functionality of a digital interface while also supporting
uncompressed video formats in a simple, cost-effective manner
• Is backward-compatible with DVI (Digital Visual Interface)
• Supports CEC, two-way communication between the video source (such as a
DVD player) and the digital television, enabling new functionality such as
automatic configuration and one-button play
• Has the capacity to support existing high-definition video formats (720p,
1080i, and 1080p, 2K and 4K), standard definition formats such as NTSC or
PAL, as well as 480p and 576p
