  1. 1. Presentation On HDMI By Naveen Kumar Tiwari
  2. 2. Agenda • Introduction about HDMI • HDMI For HDTVs • HDMI Versions • HDMI Cable Types • HDMI VS DVI • HDCP • Advantages of HDMI • Disadvantages of HDMI • HDMI Set Up • Conclusion
  3. 3. Introduction • HDMI (High-Definition Multimedia Interface) is an interface standard used for audiovisual equipment such as high-definition television and home theater systems. • The High-Definition Multimedia Interface is provided for transmitting signals to television sets, projectors and other video displays. • HDMI is the only interface enabling connections to both HDTVs and digital PC monitors implementing the DVI and HDMI standards.
  4. 4. Continue… • HDMI can deliver high quality audio or video without the risk of quality loss due to the conversion or compression of a video or audio signal. • HDMI systems automatically convert a picture into its most appropriate format, such as 16:9 or 4:3. • HDMI uses transition minimized differential signaling (TMDS) to move information from one place to another.

  6. 6. HDMI For HDTVs • Before the development of high-definition televisions, most TVs displayed pictures in what is now known as standard definition. • its aspect ratio is 4:3, so the picture is square . • HDTVs, on the other hand, are digital. They use information in the form of ones and zeros. • HDTVs have an aspect ratio of 16:9, so the picture is rectangular.
  7. 7. Continue…
  8. 8. HDMI Versions • HDMI Version 1 • HDMI Version 1.1 • HDMI Version 1.3 • HDMI Version 1.4
  9. 9. HDMI cable types • Type A • Type B • Type C • Type D • Type E
  10. 10. HDMI VS DVI HDMI Connector DVI Connector HDMI Connector DVI Connector DVI is HDMI without the audio – Separate cable needed for audio !
  11. 11. Continue… • There are actually three types of DVI. • DVI-A is used for analog signals like VGA. • DVI-D is used for digital signals. • DVI-I is a combination of DVI-A and DVI-D.
  12. 12. Continue… • High Definition Multimedia Interface is the only uncompressed, all digital audio/video interface that is supported by the industry. • High Definition Multimedia Interface provides an interface in between any video/audio source, like an A/V receiver, digital television, and DVD player over one cable total, instead of one cable for video and one cable for audio. • HDMI will support high definition video, standard video, and / or enhanced video plus multiple channels of digital audio on one single cable.
  13. 13. Continue… • There are two important differences between DVI and HDMI. • The first difference is that HDMI technology incorporates content security that is called High Definition Content Protection, also known as HDCP. • The other huge difference between Digital Video Interface and High Definition Multimedia Interface is that DVI can only support digital video, and HDMI can support audio and video on the same cable.
  14. 14. High-bandwidth Digital Content Protection • High-bandwidth Digital Content Protection encrypts data over HDMI. • HDCP helps bring high-definition digital content to consumers by providing copy protection over HDMI
  15. 15. Continue… • Developed by Intel Corporation to prevent copying of digital audio and video content as it travels across HDMI, DVI etc. • Supported by the majority of CE manufacturers, government and content providers • Emphasizes that HDMI is a smart cable
  16. 16. Continue…
  17. 17. Advantages of HDMI • Higher Quality • Intelligence • Authentication and Encryption • Signal Integrity • Single Cable • No Compression • Compatibility with DVI • Supports multiple audio and video formats • Hot Plug Detect • Display port compatibility:
  18. 18. Disadvantages of HDMI • Distance Limitations • Switching Delays • Costly • Multiple locations • Multi-Channel Audio • DVI Compatibility
  19. 19. Conclusion • HDMI is constantly evolving to meet the needs of the marketplace. The standard is constantly adding more and more features that manufacturers can implement if they desire. But HDMI does not require manufacturers to implement everything that HDMI can do. HDMI provides a menu of capabilities and allows the manufacturer to choose which of those features make sense for its product line. As you upgrade and purchase new audio and video components, you will notice HDMI becoming more of a standard connection option with increasing capabilities.
