3. Objective
• HDMI is the first & only industry supported,
uncompressed, all-digital audio/video interface,HDMI
supports standard high-definition video, plus multi-
channel digital audio on a single cable.
4. Introduction
• HDMI (High Definition Multimedia Interface)
• HDMI v1.3 vs. existing technologies such as S video and DVI.
• Active devices that are available to facilitate and distribute
HDMI.
• Opportunities for HDMI
8. HDMI over existing analog interfaces
• Because HDMI is a digital interface, it provides the best
quality of the video
• HDMI cables are more likely to be successful at carrying large
amounts of data longer distances
• Single cable for both video and audio is the most effective
format !
• The cable carries full digital audio and video at high
resolutions between source, receiver and display.
10. The Cable
• TMDS - Transition Minimized Differential Signaling
– refers to the high speed signal data, audio and video are
multiplexed, eliminating the need for audio channels
• DDC - Display Data Channel
– is a digital connection between a display and a graphics adapter that allows
the display to communicate its specifications to the adapter
– supply channel, provides power to DDC whether on/off
– simply put plug and play
• CEC- Consumer Electronics Control
– industry standard protocol, is used for remote control functions, universal
remote
14. HDMI FEATURES
• Bandwidth more than doubled from 165 MHz (4.95 Gbps) to
340 MHz (10.2 Gbps) to support Higher Resolution, and Deep
Color.
• HDMI is a conduit or pipe that moves data.
• With more bandwidth we have more room for more goodies
today and in the future.
• Backward compatible with legacy versions.
16. Deep Color
• Deep Color increases the number of bits available for
transmission for each channel.
• So, for example, a TV that accepts the 24 or 12-bit form can
mix together any one of 4,096 shades (levels of brightness) of
each primary color for 68.7 billion possible colors.
4,096 red x 4,096 green x 4,096 blue = 68,719,476,736 colors!!
17. HDMI Problems Areas
• Manufacturing, non-approved HDMI cables can produce poor
results.
• Poor installation, long cable runs, improper active devices,
lack of knowledge.
• Cost of cable is much higher compare to others.
18. What is HDCP?
• High-bandwidth Digital Content Protection encrypts data over
HDMI.
• HDCP helps bring high-definition digital content to consumers
by providing copy protection over HDMI
20. HDMI Opportunities
• HDMI is growing with the advancement of high definition
programming and DVDs.
• Video Games and PC are also integrating HDMI for
optimization of their products.
• Commercially companies are choosing HDMI, sports and
entertainment, video displays, airports, restaurants the list
goes on.
21. Commercial
• Implementation in commercial buildings i.e:
– offices,
– airport terminals
– restaurants.
• Less set top boxes due to extenders and HDMI active devices.
• Perfect for new builds using cat5e cable to extend your HDMI
signal.
22. Result of HDMI
• Current world: limited to 24 bits/
pixel color - 16 million colors
• Deep Color allows 24, 30, 36 and
48 bits/pixel color depth
Billions of colors
• Increases contrast ratios for
sharper images & greater detail
• More accurately represents
original material
