Study Notes

  • The course is Multimedia Communication (SW-416).

Course Learning Outcomes

  • Successful completion of the course will enable students to explain multimedia systems incorporating digital audio, graphics, video, pictures, integration of media, multimedia authoring, and multimedia delivery.
  • Students will discover techniques for data compression and transmission, audio and video compression, 3D modeling, and animation in multimedia.

Introduction to Multimedia

  • Multimedia combines multiple forms of media to present information, usually via a computer.
  • It integrates text, graphics, drawings, still and moving images (video), animation, and audio.
  • Information in multimedia can be represented, stored, transmitted, and processed digitally.

Multimedia Categorization

  • Linear multimedia progresses without navigational control for the viewer; a cinema presentation is an example.
  • Nonlinear multimedia is interactive, giving the viewer control over what is viewed.
  • Multimedia is no longer linear when any interactive elements are introduced.

Basic Elements of Multimedia Text

  • In multimedia technology, textual information is enhanced by sounds and pictures for understanding.
  • Hypertext enhances the meaning of written words by allowing users to click on a word or phrase to see linked references.

Basic Elements of Multimedia Graphics

  • Digital representations of non-text information are known as graphics.
  • Common uses for images include visual controls, graphical buttons, statistical findings, and photographs.

Evolution of the Concept

  • The pre-industrial age used clay tablets and woodblock printing.
  • Newspapers marked the start of communication with mass media during the industrial age, by utilizing text, graphics, and images.

Basic Elements of Multimedia Animation

  • By moving and changing a sequence of pictures or objects, animation is created on cue.
  • The illusion of movement is achieved by incrementally changing an image over time.
  • Examples of animation include Flip-Book and Claymation.

Basic Elements of Multimedia Sound and Music Files

  • Digital recordings of actual sounds such as events or music are known as sound files.
  • Audio Interchange File Format (AIFF) is used by Apple Mac systems to store sound data.
  • Waveform Audio File Format (WAV) is an audio file format standard used by Windows.
  • Digital music or MIDI files are composed sequences of data translated into sound by the computer's sound synthesizer.

Basic Elements of Multimedia Video Files

  • Digital video files like AVI and QuickTime store moving picture information that can be played on the computer screen.
  • Photographic images presented at 15-30 frames per second provide the appearance of motion.

Evolution of the Concept

  • Guglielmo Marconi invented the Radio in Italy.
  • TV was the innovative media in 20th century and changed communication.
  • Thomas A. Edison invented the moving camera in 1887.
  • Motion pictures came into full "silent era" maturity between 1894-1929.

  • The first browser called Netscape was released in 1994.

Basic Elements of Multimedia Virtual Reality

  • Creating an artificial environment with computer hardware and software provides an interactive experience.
  • Virtual Reality Modeling Language (VRML) is a technology that allows users to browse and fly through 3D space models on the Internet.

Basic Elements of Multimedia Haptics

  • Haptics is applying touch sensation and control to interaction with computer applications.
  • Haptics technology has the purpose of training hand-eye coordination.

Usage of Multimedia

  • Uses of multimedia include advertisements, art, entertainment, video conferencing, education, medicine, business, scientific research, and searching video and image databases.

Advantages of Using Multimedia

  • Multimedia is user-friendly, requiring minimal energy from the user to sit and watch while reading text, and hearing audio.
  • Utilizes many of the user's senses like seeing, hearing and talking.
  • Multimedia integrates different mediums that can be easily changed to fit different situations.

Disadvantages of Using Multimedia

  • Multimedia can be overwhelming, as it can contain too much information at once.
  • It can be expensive due to the wide array of resources used.
  • Compiling can take a long time, as well as load.

Multimedia System

  • A system is capable of processing multimedia data and applications.
  • A Multimedia System is characterized by the generation, storage, processing, manipulation and rendition of Multimedia information.

Characteristics of a Multimedia System

  • Digitized: All media is represented in digital format.
  • Distributed: The information is remote.
  • Integrated: Media is treated in a uniform way but can be independently manipulated.
  • Interactive: Affecting the information is possible.

Challenges for Multimedia Systems

  • Sequencing within the media - playing frames in correct order/time frame in video.
  • Synchronization - inter-media scheduling.
  • Lip synchronization is important for the playback of audio and animations.

Components of Multimedia Systems

  • Video cameras, audio microphones, and graphic tablets are utilized as capturing devices.
