HDMI 1.4 Features
● HDMI Ethernet Channel - Adds high-speed networking to an HDMI link, allowing users to take full advantage of their
IP-enabled devices without a separate Ethernet cable
● Audio Return Channel - Allows an HDMI-connected TV with a built-in tuner to send audio data "upstream" to a surround
audio system, eliminating the need for a separate audio cable
● 3D - Defines input/output protocols for major 3D video formats, paving the way for true 3D gaming and 3D home theater
applications
● Content Type - Real-time signaling of content types between display and source devices, enabling a TV to optimize picture
settings based on content type
● Additional Color Spaces - Adds support for additional color models used in digital photography and computer graphics
● 4K Support - Enables video resolutions far beyond 1080p, supporting next-generation displays that will rival the Digital

demands of the motoring environment while delivering true HD quality
Advantages of HDMI
● Quality HDMI transfers uncompressed digital audio and video for the highest, crispest image quality.
● Low -cost HDMI provides the quality and functionality of a digital interface while also supporting uncompressed video
formats in a simple, cost-effective manner
● Audio HDMI supports multiple audio formats from standard stereo to multichannel surround sound
● HDMI combines video and multichannel audio into a single cable, eliminating the cost, complexity, and confusion of multiple
cables currently used in A/V systems
● HDMI supports communication between the video source (such as a DVD player) and the DTV, enabling new functionality
