Multimedia Systems-1 What is Multimedia?Multimedia’ evidently means ‘The processing andpresentation of information in two or more media’, socomputers which are capable of handling text and simplegraphics, available for many years, could be called‘multimedia computers’. However, so many extra attributes have been developed that the word now usually means the processing and presentation of at least text, graphics, and pictures, if not animation and motion video, usually in colour with sound. There are many systems and activities within multimedia’s fuzzy- edged border including hypertext, image processing, compression systems, colour electronics, input technologies like scanners, cameras, and picture frame grabbers, output technologies such as displays and reprography, transmission systems, Virtual Reality, and visualization. Compact Disk media and techniques, electronic books and journals, and videoconferencing are multimedia, as are computer games and home shopping. Multimedia is more than oneconcurrent presentation medium (for example, on CD-ROM ora Web site). Although still images are a different mediumthan text, multimedia is typically used to mean thecombination of text, sound, and/or motion video. Somepeople might say that the addition of animated images(for example, animated GIF on the Web) producesmultimedia, but it has typically meant one of thefollowing:· Text and sound · Text, sound, and still or animatedgraphic images · Text, sound, and video images
· Video and sound · Multiple display areas, images, orpresentations presented concurrently · In livesituations, the use of a speaker or actors and "props"together with sound, images, and motion videoMultimedia can arguably be distinguished from traditionalmotion pictures or movies both by the scale of theproduction (multimedia is usually smaller and lessexpensive) and by the possibility of audienceinteractivity or involvement (in such case, it is usuallycalled interactive multimedia). Interactive elements caninclude: voice command, mouse manipulation, text entry,touch screen, video capture of the user, or liveparticipation (in live presentations).Multimedia tends to imply sophistication (and relativelymore expense) in both production and presentation thansimple text-and-images. Multimedia presentations arepossible in many contexts, including the Web, CD-ROMs,and live theatre. A rule-of-thumb for the minimumdevelopment cost of a packaged multimedia production withvideo for commercial presentation (as at trade shows) is:$1,000 a minute of presentation time. Since any Web sitecan be viewed as a multimedia presentation, however, anytool that helps develop a site in multimedia form can beclassed as multimedia software and the cost can be lessthan for standard video productions.
2.Briefly explain elements of drawings. Elements are actually the basics of drawing that arevery essential to be known. The various elements ofdrawing are as follows:1.Point:A point is where a drawing starts. It is nothing but adot, and is the simplest of all the elements. Even whilewriting, we begin with a point. Every drawing begins witha point. It is the most preliminary aspect of anypictorial and graphic representation. Points can beemployed in several ways, for instance, they can projectexpressions.Points are also used in drawings to give shadow andshading effects. This method of using points is known asstippling. In the figure 2.5 where you will notice howpoints have been used to fine-tune some areas by slowlydarkening and balancing them with one another. A delicatebalance had been found between these areas because if thebackgrounds were too dark it would overpower the shadow.
2.Line:Line is the most basic design ‘tool’. A line has length,width, tone, and texture. It may divide space, define aform, describe contour, and suggest direction. Lines areelementary in all sorts of geometric constructions. Theyhave vast applicability and are easy to implement.Different Categories of lines:Normal Line:Loose and free lines:Sharp line:3. Shapes:Shape occurs when the first line is drawn. The most basicdefinition of shape is the white area on the paper. Shapeis the information that is presented between two or morelines, or is the thing that is enclosed by line. Shapehelps define the object that is depicted as much as thecollection of lines that make up the object in thedrawing. Incorrect use of shape will cause the drawing to"not look like what it’s supposed to be."Several possibilities exist for creating various shapes.Drawing of shapes can take up vast dimensions rangingfrom ordinary objects, geographical drawings such as thesun, moon and the solar system to architecturalstructural like buildings. Shapes have an inner meaningassociated with them.////////////////////////////////////////////////////////For full Version visithttp://smudeassignments.blogspot.com/This work is licensed under the Creative CommonsAttribution-NonCommercial-NoDerivs 3.0 Unported License.To view a copy of this license, visithttp://creativecommons.org/licenses/by-nc-nd/3.0/ or senda letter to Creative Commons, 444 Castro Street, Suite900, Mountain View, California, 94041, USA. ///////////////////////////////////////////////////////
