INSTITUTE OF ENGINEERING AND APPLIED TECHNOLOGY Bachelor of Science in Information Technology Department Introduction to Multimedia Publishing IT 201  People who use the term “multimedia” may have quite different, even opposing, viewpoints. A consumer entertainment vendor, say a phone company, may think of multimedia as interactive TV with hundreds What is of digital channels, or a cable-TV-like service Multimedi delivered over a high-speed Internet connection. A hardware vendor might, on a? the other hand, like us to think of multimedia as a laptop that has good sound capability and perhaps the superiority of multimedia-enabled microprocessors that understand additional multimedia instructions.  Multimedia means that computer information can be What is represented through audio, Multimedi video, and animation in a? addition to traditional media (i.e., text, graphics/drawings, images).  Multimedia is the field concerned with the computer-controlled integration of text, graphics, What is drawings, still and moving images Multimedi (Video), animation, audio, and any a? other media where every type of information can be represented, stored, transmitted and processed digitally.  Multimedia is a media that uses What is multiple form of information Multimedi a? content and information processing.  In multimedia, animation is used to further enhance / enriched the experience of the user to further understand the information conveyed to them. Categories 1. Linear active content progresses of often without any navigational control for the viewer such as a cinema Multimedi presentation. a 2. Non-linear uses interactivity to control progress as with a video game or self- paced computer-based training. Hypermedia is an example of non-linear content.  1. TEXT A broad term for something that contains words to express something. Elements of Text is the most basic element of multimedia. Multimedi a A good choice of words could help convey the intended message to the users (keywords). Used in contents, menus, navigational buttons  2. GRAPHICS  Any two-dimensional figure or illustration Elements Could be produced manually (by drawing, of painting, carving, etc.) or by computer Multimedi graphics technology. a Used in multimedia to show more clearly what a particular information is all about (diagrams, picture).  3. VIDEO The technology of capturing, Elements recording, processing, transmitting, of and reconstructing moving pictures. Multimedi Video is more towards photo realistic a image sequence or live recording as in comparison to animation.  4. AUDIO Produced by vibration, as Elements perceived by the sense of of hearing. Multimedi In multimedia, audio could come a in the form of speech, sound effects and also music score. Elements 5. ANIMATION of The illusion of motion created by Multimedi the consecutive display of images a of static elements.  Multimedia finds its application in various areas including, but not limited to: Advertisements Art Usage of Education Multimedi Entertainment a Engineering Medicine Mathematics Business Scientific research  In education, multimedia can be used as a source of information. Students can search encyclopedias such as Encarta, which provide facts on a variety of different topics using multimedia presentations. Teachers can use multimedia presentations to make lessons more Usage of interesting by using animations to highlight or demonstrate key Multimedi points. a A multimedia presentation can also make it easier for pupils to read text rather than trying to read a teacher’s writing on the board. Programs which show pictures and text whilst children are reading a story can help them learn to read; these too are a form of multimedia presentation.  Multimedia is used for advertising and selling products on the Internet.  Some businesses use multimedia for training where CD- ROMs or on-line tutorials allow staff to learn at their own Usage of speed, and at a suitable time to the staff and the company. Multimedi a Another benefit is that the company do not have to pay the additional expenses of an employee attending a course away from the workplace. People use the Internet for a wide range of reasons, including shopping and finding out about their hobbies.  The Internet has many multimedia elements embedded in Usage of web pages and web browsers Multimedi support a variety of multimedia a formats. Many computer games use sound tracks, 3D graphics and video clips.  The multiple modalities of text, audio, images, drawings, animation, video, and interactivity in multimedia are put to use in ways as diverse as Componen Geographically based, real-time augmented-reality, massively multiplayer online video games, making use of ts of any portable device such as smartphones, laptops, or Multimedi tablets, which function as GPS-aware mobile game a consoles. For example, a game in which players reinforce and link friendly “portals,” and attack enemy ones that are played on GPS-enabled devices where the players must physically move to the portals (which are overlaid on real sites such as public art, interesting buildings, or parks) in order to interact with them.  Shapeshifting TV, where viewers vote on the plot path by phone text-messages, which are parsed to direct plot changes in real- time. A camera that suggests what would be the best type of next shot so as to adhere to good technique guidelines for developing Componen storyboards. ts of A Web-based video editor that lets anyone create a new video by Multimedi editing, annotating, and remixing professional videos on the cloud. a Cooperative education environments that allow schoolchildren to share a single educational game using two mice at once that pass control back and forth. ▪ Searching (very) large video and image databases for target visual objects, using semantics of objects.  Compositing of artificial and natural video into hybrid scenes, placing real- appearing computer graphics and video objects into scenes so as to take the physics of objects and lights (e.g., shadows) into account. Componen Visual cues of video-conference participants, taking into ts of account gaze direction and attention of participants. Multimedi a Making multimedia components editable—allowing the user side to decide what components, video, graphics, and so on are actually viewed and allowing the client to move components around or delete them—making components distributed.  Building “inverse-Hollywood” applications that can recreate the process by which a video was made, allowing storyboard pruning and concise video summarization. From a computer science student’s point of view, what makes multimedia interesting is that Componen so much of the material covered in traditional computer ts of science areas bears on the multimedia enterprise. In today’s digital world, multimedia content is recorded and Multimedi played, displayed, or accessed by digital information a content processing devices, ranging from smartphones, tablets, laptops, personal computers, smart TVs, and game consoles, to servers and datacenters, over such distribution media as tapes, hard drives, and disks, or more popularly nowadays, wired and wireless networks. This leads to a wide variety of research topics:  Multimedia processing and coding. This includes audio/image/video processing, compression algorithms, multimedia content analysis, content based multimedia retrieval, Usage of multimedia security, and so on. Multimedi a Multimedia system support and networking. People look at such topics as network protocols, Internet and wireless networks, operating systems, servers and clients, and databases  Multimedia tools, end systems, and applications. These include hypermedia systems, user interfaces, authoring systems, Usage of multimodal interaction, and Multimedi integration: “ubiquity”—Web- a everywhere devices, multimedia education, including computer supported collaborative learning and design, and applications of virtual environments.  It is very user-friendly. It doesn’t take much energy out of the user, in the sense that you can sit and watch the presentation, you can read the text and hear the audio. ▪ It is multi sensorial. It uses a lot of the user’s senses while making use of multimedia, for example hearing, seeing and talking. Advantages of It is integrated and interactive. All the different mediums are Using integrated through the digitization process. Interactivity is Multimedia heightened by the possibility of easy feedback. ▪ It is flexible. Being digital, this media can easily be changed to fit different situations and audiences. It can be used for a wide variety of audiences, ranging from one person to a whole group.  1. Is easy to use. 2. Enhancement of Text Only Messages 3. Improves over Traditional Audio-Video Advantages of Presentations Using 4. Gains and Holds Attention Multimedia 5. Good for “computer-phobics” 6. Multimedia is Entertaining as Well as Educational 7. Cost-effective 8. Trendy  Information overload. Because it is so easy to use, it can contain too much information at once. It takes time to compile. Even though it is flexible, it takes time to put the original draft together. It can be expensive. Disadvantag As mentioned in one of my previous posts, multimedia es of Using makes use of a wide range of resources, which can cost Multimedia you a large amount of money. Too much makes it unpractical. Large files like video and audio has an effect of the time it takes for your presentation to load. Adding too much can mean that you have to use a larger computer to store the files.  1. Expensive Disadvantag es of Using 2. Not always easy to configure Multimedia 3. Requires special hardware 4. Not always compatible   Hypertext is a text which contains links to other texts. The term was invented by Ted Nelson around 1965. Information is linked and cross-referenced in many different ways and is widely available to end users. Hypertext means a database in which information (text) has been Hypertext organized nonlinearly. The database consists of pages and links and between pages. A link is defined by source and destination nodes, and by an anchor Hypermedi in the source node. ▪ Two types of link: a  o Internal link  o External link  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. Delivering Multimedia Multimedia can be delivered using: ▪ Optical disk (CD-based) ▪ Over a distributed network (Web-based) Web-based CD-based Limited in picture Can store high end size and low Multimedia elements video resolution Can be Can be permanently changes, stored damaged or deleted by and not changeable irresponsible individuals Information can Information can be be updated quickly easily and outdated cheaper
