1. Give the generalised classes of Multimedia system classification for applications We can divide applications by use and target audience into the following generalized classes of Multimedia systems as a. Game Systems b. Multimedia information repositories c. Interactive TV(using set top systems) d. Video and Phone conferencing and hypermedia mail messages e. Shared workspaces and [...]

1. Explain very briefly about ESDI Hard Drive ESDI stands for enhanced small device interface was developed by a consortium of several manufacturers. ESDI converts the data into serial bit streams and uses the RLL encoding scheme to pack more bits per sector. ESDI drives store a defect map containing the locations of bad and [...]

Components of Microsoft Windows for pen computing System are Electronic Pen and Digitizer Pen Driver Recognition Content Manager (RC Manager) Recognizer Dictionary Display Driver Give the two types of technology based on which digitizers work Digitizers are based on two types of technologies – Electromagnetic [...]

1. What are the elements of Multimedia? The elements of multimedia are a. Facsimile b. Document Images c. Photographic Images d. Geographic Information System maps e. Voice commands and synthesis f. Audio Messages g. Video Messages h. Full Motion Stored and Live Video i. Holographic Images j. Fractals 2. What are Fractals? Fractals are regular [...]

1) Define a color model? A Color model is a method for explaining the properties or behavior of color within some particular context. No single color model can explain all aspects of color, so we make use of different models to help describe the different perceived characteristics of color. 2) Define the term hue? When [...]

Define a) Diffuse reflection and b) Specular reflection? a) Surfaces that are rough, or grainy, tend to scatter the reflected light in all directions. This scattered light is called diffuse reflection. b) In addition to diffuse reflection, light sources create highlights, or bright spots, called specular reflection. Define a) Flaps and b) Spotlights? a) Flaps [...]

1) Name the two approaches used for visible surface detection algorithm? Visible surface algorithms are broadly classified according to whether they deal with object definitions directly or with their projected images. These two approaches are called Object-space methods and Image-space methods. 2) List out the differences between object space method and image space method? Object-space [...]

1) Define Parallel projection? 1) In a parallel projection, parallel lines in the world coordinate scene project into parallel lines on the 2-d display plane. 2) This technique is used in engineering and architectural drawings to represent an object with a set of views that maintain relative proportions of the object. 2) Define Perspective projection? [...]

1) Define Translation? A translation is applied to an object by repositioning it along a straight line path from one coordinate location to another. We translate a two-dimensional point by adding translation distances, tx and ty, to the original coordinate position (x , y) to move the point to a new position(x’, y’) x’= x [...]

1) Differentiate between Windows and View port? Windows View port 1) A world coordinate area selected for Display is called a ‘window’. 1) An area on a display device to which a window is mapped is called a ‘view port’. 2) The window defines what is to be Viewed. 2) The view port defines where [...]
