Multimedia

One of the option topics studied at St Augustine’s College – Sydney

9.4.4 Option 4: Multimedia Systems

Multimedia systems are information systems that combine the different types of media. Professional multimedia systems, especially when being created, involve many participants with a wide breadth of experience. Multimedia systems encompass the entire information process. This topic emphasises the information process of displaying.

characteristics of multimedia systems

  • multimedia systems – information systems that include combinations of the following media, including:
    • text and numbers
    • audio
    • images and/or animations
    • video
    • hyperlinks
  • the differences between print and multimedia, including:
    • different modes of display
    • interactivity and involvement of participants in multimedia systems
    • ease of distribution
    • authority of document
  • use multimedia systems in an interactive way and to identify how they control the presentation of information
  • identify multimedia software appropriate to manipulating particular types of data
  • compare and contrast printed and multimedia versions with similar content

 

  • the demands placed on hardware by multimedia systems, including:
    • primary and secondary storage requirements as a result of:
      • bit depth and the representation of colour data
      • sampling rates for audio data
    • processing as a result of:
      • video data and frame rates
      • image processing, including morphing and distorting
      • animation processing, including tweening
    • display devices as a result of:
      • pixels and resolution

examples of multimedia systems

  • the major areas of multimedia use, including:
    • education and training
    • leisure and entertainment
    • information provision, such as information kiosk

    • combined areas such as educational games
  • advances in technology which are influencing multimedia development
    (See Course Specifications Document)

 

  • identify participants, data/information and information technology for one example of a multimedia system from each of the major areas
  • describe the relationships between participants, data/information and information technology for one example of a multimedia system from each of the major areas
  • discuss environmental factors that will influence the design of a multimedia system for a given context, and recommend ways of addressing them
  • critically evaluate the effectiveness of a multimedia package within the context for which it has been designed
  • interpret developments that have led to multimedia on the World Wide Web
  • discuss multimedia systems that address new technological developments
  • compare and contrast multimedia presentations

 

displaying in multimedia systems

 

  • describe how relevant hardware devices display multimedia and use a variety of devices

  • summarise the techniques for collecting, storing and displaying different forms of media and implement these in practical work
  • create samples of the different media types suitable for use in a multimedia display
other information processes in multimedia systems

  • processing:
    • the integration of text and/or number, audio, image and/or video
    • compression and decompression of audio, video and images
    • hypermedia – the linking of different media to one another
  • organising presentations using different storyboard layouts, including:
    • linear
    • hierarchical
    • non-linear
    • a combination of these
