What is Multimedia? Uses multiple forms of information content and information processing (e.g. text, audio, graphics, animation, video, interactivity) to inform or entertain the user. Use of electronic media to store and experience multimedia content.

Objectives of Multimedia Send information Educate the public Provide entertainment

Advantages of Multimedia Enhancement of Text Only Messages Improves over Traditional Audio-Video Presentations Gains and Holds Attention Good for "computer-phobics“ Multimedia is Entertaining as Well as Educational.

Disadvantages of Multimedia Information overload It takes time to compile It can be expensive Too much makes it unpractical.

Objects of Multimedia Text is the information mix of alphabets, numerals and special characters. Image is a visual representation of something. Graphics are visual images or designs on some surface, such as a wall, canvas, screen, paper, or stone to inform, illustrate, or entertain. Audio is sound within the acoustic range available to humans. Audio files are usually compressed for storage or faster transmission. Video is the representation of moving images with the mix of Audio. Animation is the process of creating the illusion of motion and shape change by means of the rapid display of a sequence of static images that minimally differ from each other.

Convergence of Multimedia At the convergence of technology and creative invention in multimedia is virtual reality, or VR. Goggles, helmets, special gloves, and bizarre human interfaces attempt to place you “inside” a lifelike experience. VR requires terrific computing horsepower to be realistic. The technology and methods for working with three-dimensional images and for animating them are discussed.

Multimedia Standards CCITT/ISO (now ITU – T) standards for multimedia include F.700, G.711, G.721, G.722, G.725, H.221, H.242, H.261, H.320, HyTime, IIF, JBIG, JPEG, MHEG, MPEG, ODA, T.80, X.400, G.723, G.726, G.727, G.728, G.764, G.765, H.200, H.241, H.243, T.120 Internet standards include IP Multicast, MIME, RTP, ST-2, RFC 741, Xv and mvex W3C standards are also very relevant Proprietary standards are Bento, GIF, QuickTime, RIFF, DVI, MIDI.
