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.
Outcomes
A student:
- H1.1 applies and explains an understanding of the nature and function of information technologies to a specific practical situation
- H1.2 explains and justifies the way in which information systems relate to information processes in a specific context

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:
- the variety of fields of expertise required in the development of multimedia applications, including:
- content providers
- system designers and project managers
- those skilled in the collection and editing of each of the media types
- those skilled in design and layout
- those with technical skills to support the use of the information technology being used
|
- summarise current information technology requirements for multimedia systems
- distinguish between different approaches to animation including path-based and cell-based through practical investigations
- describe the roles and skills of the people who design multimedia systems
|
examples of multimedia systems
- the major areas of multimedia use, including:
- education and training
- leisure and entertainment
- information provision, such as information kiosk
- virtual reality and simulations such as flight simulator
- 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
- implement features in software that support the displaying of multimedia and explain their use
- use available hardware and software to display multimedia and interact with it
- 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
- storing and retrieving:
- collecting:
- text and numbers in digital format
- audio, video and images in analog format
- methods for digitising analog data
|
- describe the process of analog to digital conversion
- plan a multimedia presentation using a storyboard
- diagrammatically represent an existing multimedia presentation with a storyboard
- design and create a multimedia presentation
- combine different media types in authoring software
- design and create a multimedia world wide web site that includes text and numbers, hypertext, images, audio and video
- identify standard file formats for various data types
- recommend an appropriate file type for a specific purpose
- describe the compression of audio, image and video data and information
- decide when data compression is required and choose an appropriate technique to compress data and later retrieve it
- capture and digitise analog data such as audio or video
|
issues related to multimedia systems
- copyright: the acknowledgment of source data and the ease with which digital data can be modified
- appropriate use of the Internet and the widespread application of new developments
- the merging of radio, television, communications and the Internet with the increase and improvements in digitisation
- the integrity of the original source data in educational and other multimedia systems
- current and emerging trends in multimedia systems
(See Course Specifications Document)
|
- evaluate and acknowledge all source material in practical work
- use Internet based multimedia presentations in a responsible way
- predict and debate new technological developments based on advancements in multimedia systems
- cross-reference material supplied in multimedia presentations to support its integrity
