Introduction to MMA 113 Multimedia PR-LEC-01 What is multi media? What is multi media? Multimedia means that computer information can be represented through audio, video, and animation in addition to traditional media (i.e., text, graphics/drawings, images). The field is concerned with the computer- controlled integration of text, graphics, drawings, still and moving images (Video), animation, audio, and any other media where every type of information can be represented, stored, transmitted and processed digitally. The Basic Elements of Multimedia TEXT GRAPHICS/IMAGES ANIMATION VIDEO AUDIO  TEXT Text is most commonly used to communicate information. It has alphanumeric characters, in addition to special characters. It involves the use of text types, sizes, fonts, colours and background colours. Multimedia applications support linked content, through Hypertext. Text in SMS, FAX, Email are examples of this element in Communication. Common file types include: TXT, DOC, DOCX, PDF.  GRAPHICS / IMAGES Images/Illustrations are the oldest forms of media They help to illustrate ideas through still pictures. There are two types of images - Bitmaps and Vector Bitmap images are real images that can be captured from devices such as cameras. Vector graphics are created using software on the computer. This multimedia element enables to generate, represent, process, manipulate, and display pictures. Common file types for Images include: JPG, PNG, TIF, BMP  GRAPHICS / IMAGES Images/Illustrations are the oldest forms of media They help to illustrate ideas through still pictures.

This multimedia element enables to generate, represent, process, manipulate, and display pictures. Common file types for Images include: JPG, PNG, TIF, BMP  ANIMATION Animation is the process of making a static image look as if it is moving. It helps in creating, developing, sequencing, and displaying a set of images technically known as frames. Digital animation can be classified as 2D two dimension and 3D Three dimension animations.  VIDEO Video presents moving pictures and typically combines images and sound for a multimedia experience. This technology records, synthesizes, and displays images known as frames in such sequences at a fixed speed that makes the creation appear as moving; this is how we see a completely developed video. To watch a video without any interruption, the video device must display 25 to 30 frames/second. Common file types for Video include AVI, WMV, FLV, MOV, MP4  AUDIO The speech, music, and sound effects used in multimedia are digital audio. Multimedia applications use audio or sound element, websites or presentations can add audio files from a musical background, or a voiceover / spoken explanation. There are two basic types of audio or sound; analog and digital. The original sound signal is termed Analog audio. The digital sampling of the original sound is termed Digital audio. Common file types for Audio include: MP3, WAV, WMA Categories of Multimedia LINEAR NONLINEAR  LINEAR Active content progresses often without any navigational control for the viewer such as a cinema presentation.  NON-LINEAR Content offers user interactivity to control progress as used with a computer game or used in self-paced computer-based training. Non-linear content is also known as hypermedia content. APPLICATION OF MULTIMEDIA Creative industries Creative industries use multimedia for a variety of purposes ranging from fine arts, to entertainment, to commercial art, to journalism, to media and software services provided for any of the industries listed below. An individual multimedia designer may cover the spectrum throughout their career. Request for their skills range from technical, to analytical and to creative. Commercial Much of the electronic old and new media utilized by commercial artists is multimedia. Exciting presentations are used to grab and keep attention in advertising. Industrial, business to business, and interoffice communications are often developed by creative services firms for advanced multimedia presentations beyond simple slide shows to sell ideas or liven-up training. Commercial multimedia developers may be hired to design for governmental services and nonprofit services applications as well. Entertainment and Fine Arts In addition, multimedia is heavily used in the entertainment industry, especially to develop special effects in movies and animations. Multimedia games are a popular pastime and are software programs available either as CD-ROMs or online. Some video games also use multimedia features. Multimedia applications that allow users to actively participate instead of just sitting by as passive recipients of information are called Interactive Multimedia. Education In Education, multimedia is used to produce computer-based training courses (popularly called CBTs) and reference books like encyclopedias and almanacs. A CBT lets the user go through a series of presentations, text about a particular topic, and associated illustrations in various information formats. Edutainment is an informal term used to describe combining education with entertainment, especially multimedia entertainment. Engineering and Architecture Use multimedia in computer simulations for anything from entertainment to training, presenting, reproducing or industrial training. Multimedia for software interfaces are often done as a collaboration between creative professionals and software engineers. Mathematical and Scientific Research In Mathematical and Scientific Research, multimedia is mainly used for modeling and simulation. For example, a scientist can look at a molecular model of a particular substance and manipulate it to arrive at a new substance. Medicine In Medicine, doctors can get trained by looking at a virtual surgery, or they can simulate how the human body is affected by diseases spread by viruses and bacteria and then develop techniques to prevent it. Multimedia in Public Places In hotels, railway stations, shopping malls, museums, and grocery stores, multimedia will become available at stand- alone terminals or kiosks to provide information and help. Such installation reduce the demand for traditional information booths and personnel, add value, and they can work around the clock, even in the middle of the night, when live help is off duty. Convergence of Multimedia (Virtual Reality) 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. Hypertext and Hypermedia Hypertext is a text which contains links to other texts. The term was invented by Ted Nelson around 1965. Hypermedia is not constrained to be text-based. It can include other media, e.g., graphics, images, and especially the continuous media – sound and video. References: 1. “Multimedia Making it work” By Tay Vaughan 2. “Multimedia in Practice – Technology and Applications” By Jeffcoat 3.
