The document summarizes HDMI (High Definition Multimedia Interface) technology. It discusses HDMI versions 1.3 and the advantages over existing technologies like S-video and DVI, including supporting uncompressed digital audio and video over a single cable. It also describes typical HDMI component setups, cables, features like deep color and increased bandwidth, commercial applications, and concludes that HDMI is very useful for high definition multimedia as an interface without quality degradation.

2. Outline
• Objective
• Introduction
• Methodology
• Implementation Detail
• Result Analysis

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

5. Typical Component Set-Up

6. Typical HDMI Set-Up

7. Typical HDMI Cables

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.

9. The HDMI Cable

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

11. HDMI Configuration

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.

15. HDMI 1.0/1.2 Versus 1.3

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

19. How it works

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

23. Typical HDMI Set Up

24. Conclusion
• For High definition multimedia it is very useful
as an interface without any quality
degradation .
