1 MC0713 MULTIMEDIA SYSTEMS UNIT - I 1. Definition Multimedia is any combination of text, graphic art, sound, animation and video delivered to us by computer or other electronic means. 1.1 CD-ROM and Multimedia Highway  Compact Disc-Read Only Memory (CD-ROM) is a cost effective distribution medium for multimedia projects.  It can contain unique mixes of images, sounds, text, video, and animations controlled by an authoring system to provide unlimited user interaction.  Digital Versatile Disc (DVD) technology has come into usage which has increased capacity than the CD-ROM.  Now that telecommunications are global, information can be received online as distributed resources on a data highway, where we will pay to acquire and use multimedia based information. 1.2 Where to use multimedia? Multimedia in business  Business applications for multimedia include presentations, training, marketing, advertising, product demos, databases, catalogues and networked communications..  Multimedia is used in voice mail and video conferencing.  Multimedia is used in training programs.  Mechanics learn to repair engines through simulation.  Sales person learn about the products online Prepared By: F.

2  Pilots practice before spooling up for the real thing. Multimedia in Schools  Multimedia provides radical changes in the teaching process, as smart students discover they can go beyond the limits of traditional teaching methods.  Teachers may become more like guides and mentors along a learning path, not the primary providers of information and understanding.  It provides physicians with over 100 case presentations and gives cardiologist, radiologist, medical students, and fellows an opportunity for in-depth learning of new clinical techniques.  Adults and children learn well by exploration and discovery. Multimedia at home  From gardening to cooking to home design , remodeling multimedia has entered the home. Multimedia in public places  In hotels, train stations, shopping malls, museums and grocery stores, multimedia will become available at stand-alone terminals or kiosks to provide information and help.  Such installations reduce demand on traditional information booths and personnel and they can work round the clock, when live help is off duty.  Supermarket kiosks provide services ranging from meal planning to coupons.  Hotel kiosks list nearby restaurants, maps of the city, airline schedules, and provide guest services such as automated checkouts.

Introduction to making multimedia 2.1 The stages of a project Most multimedia and web projects must be undertaken in stages.Here are four basic stages in a multimedia project. Planning and Costing  Before we begin developing , we need to plan what writing skills, graphic art, music, video, and other multimedia expertise will be required.  We need to develop a creative graphic look and feel, as well as a structure and navigation system that will let the viewer visit the message and content.  We need to estimate the time needed to do all elements and prepare a budget. Designing and producing  To perform each of the planned tasks to create a finished product. Testing Always we need to test our programs to make sure  They meet the objectives of our project  They work properly on the intended delivery platforms  They meet the needs of your client or end user Delivering Prepared By: F.

Hardware  The Macintosh OS from Apple  Intel-based IBM PC running Microsoft Windows  These computers with their GUI are the most commonly used platforms today for the development and delivery of multimedia. Software  Tools for capturing screen images, translating between file formats and editing our resources.  Common tools such as word processors, spreadsheets and databases for presenting instant multimedia.  Multimedia authoring tools  Tools for designing and delivering multimedia on the web. Creativity  Before we begin a multimedia project, we must first develop a sense of its scope and content.  The most precious asset we can bring to the multimedia workshop is our creativity. Organization  It is essential we develop an organized outline and a plan that rationally details the skills, time, budget, tools and resources we will need for a project. 3.
