Multimedia System : Multimedia System Design In Technology

 Multimedia System Design In Technology : A Multimedia System is a system capable of processing multimedia data and applications.

 A Multimedia System characterized by the processing, storage, generation, manipulation and rendition of Multimedia information.

Multimedia Document : Multimedia System Design In Technology

 A multimedia document is a natural extension of a conventional textual document in the multimedia area.

 It defined as a digital document that composed of one or multiple media elements of different types (text, image, video, etc.) as a logically coherent unit.

Multimedia Document Architecture and Structure : Multimedia System Design In Technology

 Multimedia document architecture and structure refers to the base data storage system in a multimedia document.

Multimedia Document Imaging : Multimedia System Design In Technology

 Document Imaging means the conversion of paper files (of any size or description) or microfilm / fiche to digital images.

 Document imaging is a form of enterprise content management.

Issues of Multimedia System Design : Multimedia System Design In Technology

 Bandwidth – capacity of the transfer mechanism. Its between source and destination.

 Delay – the time a multimedia unit spends in transmission. Its from source to destination.

 Delay Jitter – Variation in delay. Its delivery of data

 Loss Probability – the ratio of units of information. That an application can afford to lose.

Digital Representation

 Digital representation of multimedia. Which means the digital representation of the multimedia elements.

 Digital Audio played. Back through audio player. Speaker, audio card and MP3 Player.

 Digital Images displayed in computer monitors. Printed form printers.

 Digital Videos played back from Computer Video Players. Portable DVD/Blu-Ray Players in Computer Monitors or TV Screens


 Digital Text or e-text is a electronic version of a written text. Digital Text can found on the internet or on your computer or on a variety of hand-held electronic devices.

Text Representation

 ANSI. American National Standards Institute

 Unicode. Universal Code

 UTF-8. Unicode Transformation Format – 8 Unicode Characters

 ASCII. American Standard Code for Information Interchange

 RTF. Rich Text Format

RTF (Rich Text Format)

 The Rich Text Format (often abbreviated RTF) a proprietary document file format with published specification developed by Microsoft Corporation from 1987 until 2008 for cross-platform document interchange with Microsoft products.

 Most word processors are able to read and write some versions of RTF.

Digital Image

 A digital image is a numeric representation (normally binary). Its of a two-dimensional image.

 Depending on whether the image resolution fixed. It may be of vector or raster type.

 By itself, the term “digital image” usually refers to raster images. Bitmapped images.

Pixel Bit Depth – 2/4/8/16/32 Bits

 Color depth, also known as bit depth, either the number of bits used to indicate the color of a single pixel, in a bitmapped image or video frame buffer, or the number of bits used for each color component of a single pixel


 Image resolution is the detail an image holds. The term applies to raster digital images, film images, and other types of images.

 Higher resolution means more image detail.

Image Representation

 In computer graphics, a raster graphics image is a dot matrix data structure representing a generally rectangular grid of pixels, or points of color, viewable via a monitor, paper, or other display medium. Raster images stored in image files with varying formats.


 The RGB color model in a computer monitor display that an additive color model in which red, green, and blue light added together in various ways to reproduce a broad array of colors.

 Colors represented using Hexadecimal values in computers.

Luminance and Chrominance Components

 Luminance is a photometric measure of the luminous intensity per unit area of light travelling in a given direction. It describes the amount of light that passes through, emitted or reflected from a particular area, and falls within a given solid angle.

 Chrominance (chroma or C for short) the signal used in video systems to convey the color information of the picture, separately from the accompanying luma signal (or Y for short). Chrominance usually represented as two color-difference components: U = B′ − Y′ (blue − luma) and V = R′ − Y′ (red − luma)


 Vector graphics is the use of polygons to represent images in computer graphics.

 Vector graphics are based on vectors, which lead through locations called control points or nodes.

Pulse Amplitude Modulation

 Pulse Amplitude Modulation (PAM) is the simplest form of pulse modulation. This technique transmits data by varying the voltage or power amplitudes of individual pulses in a timed sequence of electromagnetic pulses.

 In other words, the data to transmitted encoded in the amplitude of a series of signal pulses.
