SCOPE OF THE COURSE: this lecture REQUIREMENTS exam+exercises WEB PAGES – course powerpoints available MULTIMEDIA SYSTEMS IREK DEFEE
CONCEPTS OF MULTIMEDIA AND DIGITAL MEDIA PROBLEMS AND REQUIREMENTS FOR MULTIMEDIA DATA MULTIMEDIA COMPRESSION AND DATA HANDLING SIGNAL MODULATION FOR DATA TRANSMISSION COURSE OVERVIEW MULTIMEDIA SYSTEMS IREK DEFEE
COMMUNICATION NETWORKS AND SYSTEMS, WIRED NETWORKS ARCHITECTURE OF WIRELESS MULTIMEDIA – RADIO LINKS AND TECHNIQUES MULTIMEDIA DATA TRANSPORT NETWORKS AND PROTOCOLS MULTIMEDIA SYSTEMS OTHER ISSUES MULTIMEDIA SYSTEMS IREK DEFEE
WHAT IS MEDIA? - SPECIFIC CARRIER OF INFORMATION MULTI+MEDIA – MULTIPLE CARRIERS OF INFORMATION MEDIA INDUSTRY – BUSSINESS OF PRODUCING AND HANDLING INFORMATION CONCEPTS MULTIMEDIA SYSTEMS IREK DEFEE
MULTIMEDIA USED IN TWO WAYS - HUMAN INFORMATION AND COMMUNICATION SYSTEM USES MULTIPLE MEDIA - MEDIA INDUSTRY IS MOVING TOWARDS DIGITAL MEDIA MULTIMEDIA SYSTEMS IREK DEFEE
HUMAN PERCEPTUAL SYSTEM COMPOSED OF SENSES: VISUAL - INPUT ACOUSTICAL – I/O HAPTIC – I/O (TOUCH, SKIN SENSORS ,MOTORIC SYSTEM) TASTE, SMELL BRAIN IS PROCESSING, CONTROLLING AND COORDINATION CENTER FOR SENSES MULTIMEDIA SYSTEMS IREK DEFEE
HUMAN SENSES ARE PERFECTLY COORDINATED INTO A FULLY INTEGRATED SYSTEM THIS SYSTEM CAN RECEIVE AND PROCESSES MULTIMODAL INFORMATION FROM THE SENSES AND PRODUCE MULTIMEDIA OUTPUT SEEMINGLY WITH NO EFFORT MULTIMEDIA SYSTEMS IREK DEFEE
HOW THIS IS DONE IN THE BRAIN WE DON’T KNOW EXACTLY HUMAN ARE FANTASTIC MULTIMEDIA ”SYSTEMS” - MANY ENCODING LEVELS OF INFORMATION FROM BASIC TO ABSTRACT: SOUNDS, SPEECH-LANGUAGE, MUSIC GESTURES, READING, WRITING MULTIMEDIA SYSTEMS IREK DEFEE
HUMAN SENSORY SYSTEM IS OPTIMIZED TO PRODUCE AND RECEIVE MULTIMODAL INFORMATION – BUT OPTIMALITY IS DONE ON MANY LEVELS SINGLE MEDIA MIGHT BE BORING (SPEECH), MULTIMEDIA MIGHT BE EXCITING, BUT IT DEPENDS ON THE CONTENT OF INFORMATION MULTIMEDIA SYSTEMS IREK DEFEE
WHAT IS MULTIMEDIA FROM THE POINT OF HUMAN PERCEPTION? IT IS USING MULTIMODAL INFORMATION TO ACHIEVE OPTIMAL STIMULATION - CINEMA EXAMPLE: VISUAL AND ACOUSTICAL STIMULATION IS USED BUT MUSIC HAS ITS SUBTLE IMPORTANT ROLE MULTIMEDIA SYSTEMS IREK DEFEE
BUT HUMAN SYSTEM IS BOTH RECEIVING AND PRODUCING INFORMATION, THIS MEANS BOTH THESE PARTS SHOULD BE USED OPTIMAL STIMULATION IS THEN DESCRIBED AS: ’FULL INVOLVEMENT’, ’ENLIVED EXPERIENCE’ (EXAMPLE: COMPUTER GAMES) MULTIMEDIA SYSTEMS IREK DEFEE
MULTIMEDIA TECHNOLOGY AIMS TO PROVIDE (SOME) MATCHING OF INFORMATION DEVICES TO HUMAN PERCEPTION SYSTEM MULTIMEDIA SYSTEM: INTERFACE, PROCESSING, DELIVERY OF INFORMATION NETWORK MULTIMEDIA SYSTEMS IREK DEFEE
DIGITAL MEDIA DIGITAL MEDIA IS A CONCEPT OF INTEGRATION OF DIFFERENT MEDIA INDUSTRIES ON DIGITAL PLATFORM MEDIA INDUSTRY IS A BUSSINESS WHOSE PRIMARY PRODUCT IS INFORMATION IN VARIOUS FORMS MASS MEDIA – INDUSTRIES WHICH DO THIS ON HUGE SCALE MULTIMEDIA SYSTEMS IREK DEFEE
TRADITIONALLY MEDIA INDUSTRIES EMERGED BECAUSE SPECIFIC TECHNOLOGIES WERE INVENTED: - BOOKS - NEWS - CINEMA - RADIO - TELEVISION - TELEPHONE PAPER, PRINTING CELLULOID, PHOTOGRAPHY ELECTRONICS MULTIMEDIA SYSTEMS IREK DEFEE
MEDIA INDUSTRY IS OFFERING A SERVICE CONSUMER CONTENT DELIVERY DISTRIBUTION MULTIMEDIA SYSTEMS IREK DEFEE
THE SERVICE CARRIERS EVOLVED AROUND SPECIFIC TECHNOLOGIES: - PAPER, PRINTING - CELLULOID TAPE,PHOTOGRAPHY - RADIO SIGNALS, ELECTRONIC DISPLAYS MULTIMEDIA SYSTEMS IREK DEFEE
THE SERVICE CHAIN IS ORGANIZED AROUND CERTAIN TECHNOLOGY, FOR EXAMPLE PRINTING INDUSTRY INVOLVES PAPER AND PRINT: CONTENT IS WRITTEN BY EDITORS AND WRITERS PRINTING FACTORIES TRANSFER IT ON PAPER PAPER COPIES ARE PHYSICALLY DELIVERED TO CONSUMERS ANOTHER EXAMPLE: TELEVISION INDUSTRY INVOLVES ELECTRONICS: CONTENT IS PRODUCED IN STUDIOS DISTRIBUTION NETWORKS AND TRANSMITTERS DELIVER IT TO CONSUMERS BY RADIO WAVES – TO TV SETS MULTIMEDIA SYSTEMS IREK DEFEE
TRADITIONAL MEDIA INDUSTRIES PROVIDE BROADCAST SERVICE INFORMATION IS PRODUCED IN ONE CENTER AND DELIVERED FROM THERE – OFTEN PHYSICALLY EXAMPLE – CD RECORDING INDUSTRY OTHER TYPES OF SERVICES: - RETRIEVAL, ON-DEMAND - COMMUNICATIVE (WWW, INTERNET) MULTIMEDIA SYSTEMS IREK DEFEE
TRADITIONAL MEDIA INDUSTRIES WERE • STRICTLY SEPARATED • TECHNOLOGIES AND DISTIRBUTION • CHANNELS WERE DIFFERENT, FOR • EXAMPLE PRINTING AND TELEVISION • DIGITAL TECHNOLOGY IS UNIVERSAL • EVERY MEDIA TYPE CAN BE EMBEDDED • IN IT AND IT IS NOT TIED TO PHYSICAL • MEDIA MULTIMEDIA SYSTEMS IREK DEFEE
TV AND RADIO ARE MEDIA WITH NO PHYSICAL CARRIER, ELECTRONIC MEDIA BUT THEY INVOLVE SPECIFIC MEDIA REPRESENTATION (”ANALOG”) DIGITAL REPRESENTATION IS UNIVERSAL, CAN REPRESENT ANYTHING AND DOES NOT DEPEND ON SPECIFIC CARRIER DIGITAL MEDIA REVOLUTION MULTIMEDIA SYSTEMS IREK DEFEE
DIGITAL MEDIA INTEGRATES ALL TRADITIONAL MEDIA INDUSTRIES TV -> Digital TV BOOKS -> Digital Books PAPER -> Digital Paper CINEMA -> Digital Cinema + New Media -> Web, Games…. MULTIMEDIA SYSTEMS IREK DEFEE
ALL MEDIA PRODUCTION WILL BE DIGITAL IN THE FUTURE WILL ALL MEDIA INTERFACES BE DIGITAL? E.G. WILL DIGITAL PAPER COME? THIS WE DON’T KNOW YET... MULTIMEDIA SYSTEMS IREK DEFEE
NEW MEDIA = MULTIMEDIA - DIGITAL - MULTIPLE MEDIA TYPES - INTERACTIVE - ON-DEMAND (THAT IS NON-BROADCAST) MULTIMEDIA SYSTEMS IREK DEFEE
INFORMATION DELIVERY BREAKING WITH PHYSICAL CARRIERS AND TRANSPORT : - NON-PHYSICAL TRANSPORT - ELECTRONIC - NETWORKED: - WIRED - WIRELESS MULTIMEDIA SYSTEMS IREK DEFEE
BY DEVELOPING MULTIMEDIA SYSTEMS BY ELIMINATING OLD MEDIA BY CREATING NEW MEDIA THE GOAL OF THIS COURSE: TO REVIEW MULTIMEDIA SYSTEMS TECHNOLOGY HOW THIS WILL HAPPEN? MULTIMEDIA SYSTEMS IREK DEFEE
SOME EXAMPLESWILL FOLLOW.... MULTIMEDIA SYSTEMS IREK DEFEE
THERE ARE MANY DIGITAL MEDIA DEVICES: Digital cameras Camcorders Music players Multimedia players Game consoles MULTIMEDIA SYSTEMS IREK DEFEE
TRADITIONAL MOBILE PHONES BECOME MEDIA DEVICES Music Games Reading MULTIMEDIA SYSTEMS IREK DEFEE
Digital camera iPod Portable game player (Playstation) Each of these devices can be connected to the network Or… they can be integrated into a single device… with a mobile phone MULTIMEDIA SYSTEMS IREK DEFEE
Universal mobile devices Iphone MULTIMEDIA SYSTEMS IREK DEFEE
camera camcorder TV radio game PDA What is mobile device? makeup device? Swiss army knife? MULTIMEDIA SYSTEMS IREK DEFEE
NEW TYPES OF DEVICES: Tablet computer Book reader MULTIMEDIA SYSTEMS IREK DEFEE
New types of devicesApple iPad It is thin, it has network connection It can replace books and newspapers, Can be used as calendar, for watching videos MULTIMEDIA SYSTEMS IREK DEFEE
SIMILAR DEVELOPMENTS ARE ALSO HAPPENING FOR HOME MEDIA, DEVICES WHICH ARE USED IN THE LIVING ROOM HAVE JUST BIGGER SIZE, ESPECIALLY THE DISPLAY HOME MEDIA MULTIMEDIA SYSTEMS IREK DEFEE
TV in 2011 is Smart TV +3D • New TV sets have Internet built-in connectivity • Internet and Web browser • Wi-Fi - wireless • DLNA - home network support • Access to networked content 3D glasses MULTIMEDIA SYSTEMS IREK DEFEE
FLAT DISPLAYS They are getting huge…. 80" Diagonal ~2 meters Smart TV MULTIMEDIA SYSTEMS IREK DEFEE
GAME CONSOLES ALSO BECOMING MEDIA DEVICES LIKE E.G. MICROSOFT XBOX MULTIMEDIA SYSTEMS IREK DEFEE
MICROSOFT KINECT Kinect is a sensor which is attached to XBOX. This sensor measures distance to objects and finds movements Kinect users can interact with content using body movements and gestures MULTIMEDIA SYSTEMS IREK DEFEE
WE CAN THINK ABOUT FUTURE MEDIA • DEVICES, WHICH STILL MAY COME…. • ELECTRONIC PAPER • ROBOTS • NEW FORMS OF ENTERTAINMENT • …. • AND PERHAPS MUCH MORE MULTIMEDIA SYSTEMS IREK DEFEE
Produced in a roll, like old-fashioned paper, SmartPaper™ is actually two sheets of thin plastic with millions of tiny bichromal beads embedded in between. Each bead is smaller than a grain of sand and has a different color on each half or “side ”. The hemispheres are also charged differently (i.e. positive or negative). SmartPaper™ beads reside in their own cavities within the flexible sheet of material, so that under the influence of a voltage applied to the ELECTRONIC PAPER E-INK: check www.eink.com MULTIMEDIA SYSTEMS IREK DEFEE
PERSONAL ROBOTS MAY START APPEARING ... MULTIMEDIA SYSTEMS IREK DEFEE
Robots can do useful things…. MULTIMEDIA SYSTEMS IREK DEFEE
THESE ROBOTS MAY LOOK LIKPEOPLE ACTROID – HUMAN-LIKE ROBOT MULTIMEDIA SYSTEMS IREK DEFEE
Pet robots too MULTIMEDIA SYSTEMS IREK DEFEE
IT HAS SENSES: MICROPHONE, CAMERA, TEMPERATURE, DISTANCE, ACCELERATION, BALANCE, TOUCH IT HAS INSTINCTS AND BEHAVIORS
Devices integrated in glasses, Images projected on the glasses appear to be hanging in space
All these devices can be connected wirelessly and cooperate MULTIMEDIA SYSTEMS IREK DEFEE
