HDMI 1.4a
This topic explains the HDMI 1.4a and its features along with the advantages.
HDMI (High-Definition Multimedia Interface) is an industry-supported, uncompressed, all-digital audio/video interface. HDMI
provides an interface between any compatible digital audio/video source, such as a DVD player, or A/V receiver and a
compatible digital audio and/or video monitor, such as a digital TV (DTV). The primary advantage is cable reduction and content
protection provisions. HDMI supports standard, enhanced, or high-definition video, plus multichannel digital audio on a single
cable.
HDMI 1.4a 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
Cinema systems used in many commercial movie theaters.
● HDMI Micro Connector - A new, smaller connector for phones and other portable devices, supporting video resolutions up
to 1080p.
● Automotive Connection System - New cables and connectors for automotive video systems, designed to meet the unique
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.
