HD has four or five million pixels per frame, roughly five times that of SD. Early HDTV broadcasting used analog techniques, but today HDTV is digitally broadcast using video compression. INTRODUCTION Why the Change to HDTV ? : Increased number of programs, local broadcasters can provide. HDTV has over five times the sharpness and clarity of analog broadcasts together with a far superior color resolution. Improved Quality of Picture and Sound. Wider screens. Converting to HDTV will also free up parts of the space and valuable broadcast airwaves. Those portions of the airwaves can then be used for other important services. Why the Change to HDTV ? HDTVs : LCD TV PLASMA TV LED BACKLIT LCD TV OLED TV HDTVs LCD TV : Most mature flat panel technology Poor intrinsic viewing angle. ( hyperlink) LCD TV PLASMA TV : PLASMA TV Nobel gasses & little amount of mercury is used. Mercury gets vapourised & gasses forms plasma(collection of particles that responds strongly to the applied field). Now electrons strikes to phosphorous painted on the inside wall of pixel & light gets emitted. LED BACKLIT LCD TV : LED BACKLIT TV is an LCD TV that uses LED backlighting rather than fluorescent lights used in traditional LCD televisions. LED BACKLIT LCD TV OLED TV : OLED’s are simple solid-state devices comprised of very thin films of organic compounds in the electro-luminescent layer. The organic compounds are designed to be in between two electrodes. Out of these one of the electrodes should be transparent. The result is a very bright and crispy display . Lesser power consumption as compared to LCD & LED BACKLIT TV’s It comprises : An emissive layer A conducting layer A substrate Anode and cathode terminals. OLED TV OLED TV : The substrate is used to support the OLED. The conducting layer is used to carry the holes from the anode. The emissive layer is the section where the light is produced. This layer is also used to carry the electrons from the cathode. OLED TV MICROSOFT SURFACE : Introduced in 2007 A surface computing platform from Microsoft.(A form of computing that offers “a natural way of interacting with information,” rather than the “traditional user interface.”) “Microsoft Surface represents a fundamental change in the way we interact with digital content. With Surface, we can actually grab data with our hands, and move information between objects with natural gestures and touch. Surface features a 30-inch tabletop display. (sf) Microsoft Surface uses cameras and image recognition in the infrared spectrum to recognize different types of objects such as fingers, tagged items and shapes. This input is then processed by the computer and the resulting interaction is displayed using rear projection. MICROSOFT SURFACE MICROSOFT SURFACES : MICROSOFT SURFACES MICROSOFT SURFACE : MICROSOFT SURFACE The Surface uses multiple infrared cameras beneath the screen/table top to sense objects, physical touch, etc. The Surface “recognizes objects based on shape or by using software based identification techniques.” This information is processed and displayed using “rear projection”. It uses a normal CPU as in a simple PC. MICROSOFT SURFACE : (1) Screen: Diffuser -> ”multitouch" screen. Can process multiple inputs and recognize objects by their shapes or coded "domino" tags. (2) Infrared: The ”machine vision" is aimed at the screen. Once an object touches the tabletop -> the light reflects back and is picked up by infrared cameras. (3) CPU: Uses similar components as current desktop computers -> Core 2 Duo processor, 2GB of RAM and a 256MB graphics card. Wireless communication -> WiFi and Bluetooth antennas (future -> RFID). Operating system -> modified version of Microsoft Vista. (4) Projector: Uses a DLP light engine ( rear-projection HDTVs). (DLP) MICROSOFT SURFACE SPECIAL CHARATERISTICS : Direct Interaction: The ability to "grab" digital information with hands - interacting with touch/gesture, not with a mouse or keyboard. Multi–Touch: The ability to recognize multiple points of contact at the same time, not just one (Ex. one finger, like with most touch screens), but dozens. Multi–User: The Surface’s screen is horizontal, allowing many people to come together around it and experience a “collaborative, face–to–face interaction experience”. Object Recognition: Physical objects can be placed on the Surface’s screen to “trigger different types of digital responses” (Ex. cell phones, cameras, & glasses) SPECIAL CHARATERISTICS FUTURE OF HDTV : However, lots of progress has been done in the field of HDTV technologies ,HDTV still has much lower resolution than 70mm film. It’s a matter of time before some will begin pressuring for another increase in quality. FUTURE OF HDTV Slide 17: THANK YOU You do not have the permission to view this presentation.
