The concept of multimedia
• Multimedia is used in different ways for
several purposes by individuals, businesses,
government, schools, filmmakers, musicians

MEDIA
– Human Computer Interaction (HCI) also refer to Text,
picture, sound, video, graphics and animation as
INTERACTION MEDIA

Multimedia in terms of ICT
• Multimedia can be created and presented
digitally or analogue
• But in terms of computer science multimedia
is created digitally and presented digital
format.
• Computer multimedia content are discrete
that is they are presented in bits which ONEs
or ZEROs (1s or 0s).

• Multimedia in terns of ICT have the following
attributes:
– Digitized: They are created and presented in a digital
format
– Distributed: The content is transmitted remotely,
offline, online or real-time over a network
– Interactive: The user has the opportunity to control or
manipulate the digital multimedia content
– Integrated: The various elements in a digital
multimedia are uniformly treated as one and
presented as one content, however they can be
manipulated independently.

• Digital multimedia is the combination of text,
graphics (still or animated), sound, and video
to create content which is delivered by a
computer system or device.
• It is a technique of putting together text,
image, audio, video, graphic and animation in

– Linear
• Content is presented without the user having the
chance to control the presentation. Eg. cinema
– Non Linear
• Give the user the opportunity to interact with the
content as is presented. Eg. Computer game, recorded
production on CD etc.

created. At point you have to indicate which element will go here and there
and at what time. This where the visualization of the production is
conceptualized.
– After the story board, construction can take place where a prototype of the
production is made and tested and reviewed. After this the graphic designer
can be given specific details to create graphics and other media elements
– After all the above the programmer assembles them into a final product using
any convenient multimedia authoring application program.
