3 What Is Multimedia ? Multi Media Multimedia Multi refer to many or multipleMediaVehicle or agent to convey for somethingExample: air for sound, writing for wordsComputer is a medium for ideas and information- Express and communicate these ideas- Store and manipulate information in many different forms
4 What Is Multimedia ? Multimedia Multimedia Systems Presentation of a computer application (usually interactive)Incorporating media elements such as text, graphics, video, animation and sound on a computer.Multimedia Systemsencompass the computer and software systems that are used in multimedia environmentsInteractive controlDistributed multimedia systemsoperate over some form of network infrastructure

10 Modern multimedia PCs 3D graphics cards with 64 MB of graphics memory 64 note sound cards with wavetable synthesis256 MB of main memory60+ GB hard disk space50+ speed CD readers56 Kb/s modem or ISDN connection
11 Multimedia TypesThe main multimedia data types we will meet on this course are:- Images, video, audio, text, and animationWe will also discuss how we capture this data...- capture = get it into the computer...and render this data- render = display or play the informationWe will also find out about the hardware devices that are used to capture and render the data
12 Multimedia Applications Multimedia applications can be linear or interactiveLinear multimedia plays from some start position to some end position with little or no intervention- Just like this lectureInteractive multimedia allows the viewer to jump around the material by interacting with it
13 Multimedia Industry Structure Content(Media)Applications(Software)Platforms(Hardware)NetworkingLevel 1Level 2Level 3Level 4
14 Multimedia Industry Structure Level 1- Consists of MM content providers, for example the news industry, the television industry and the entertainment industry.Level 2- Consists of multimedia application developers.- Applications include distance learning, desktop videoconferencing, multimedia kiosks, entertainment and imaging.Level 3- Consists of MM platform builders.- These builders include Silicon Graphics, Sun, Intel, Apple, and other hardware vendors.
15 Multimedia Industry Structure Level 4- The network infrastructure.- There are two very different networking environments that will useMM applications:- business networks and- the emerging public networks.
