DATA &APPLICATIONS
LECTURE 3

2. Multimedia DATA
 MultiMedia (MM) information, such as text,
audio, images, video, animation, and
interactive data, allows fast and effective
communication about people' lives, their
behaviors, works, interests;they are also
the digital testimony of facts, objects, and
locations.

3. Concept development
 The starting point is an initial idea or concept.
 Rough storyboards can be used as an aid to
visualization.
 A feasibility study may be carried out and initial
estimates of costs, timescales and, where
appropriate, projected revenue made.
 These estimates are often based on previous work.
 A production overview document called the proposal
or brief can then be developed. This document
should include an outline of how the subject is to be
approached, the scope of the project and the
intended audience.

4. Multimedia Development Life Cycle
The exact approach taken varies from organization
to organization and depends on the complexity of
the project, but in general all projects go through
the following stages or phases.
 Concept development
 Requirements specification
 Design
 Prototype
 Production
 Testing and evaluation
 Delivery
These development stages generally overlap and involve
much iteration. This can make planning and reporting
problematic.

5. Multimedia Development Life Cycle
 To be successful, the proposal must be ‘highly readable,
and concise’ and be slanted to suit the type of production.
 The proposal is often delivered face to face, and hence
good personal communications are required. In this
situation, a storyboard may be used as a graphical aid to
communicating the idea.
 A multimedia developer may then pitch their proposal to a
potential client in a bid to get them to commission their
proposed project.
 Alternatively a client may ask a number of developers to
pitch for a given project they have in mind.
 Once the client and developer have agreed in principle to
go ahead with the project, a detailed content outline,
schedule and budget can then be drawn up

6. 2.Requirements Specification
 The next stage is to produce a more detailed requirement
specification.
 The treatment is expanded in detail to include all the aims, objectives
and subject scope, which were covered in the successful in previous
proposal.
 The requirements should also specify when the application is to be
developed and at what cost. The requirements specification allows

the client and developer to agree the scope, deadline and
deliverables of the final product
 The requirement specification should cover the minimum hardware
and software configuration(s) needed to run the application, the
intended audience and the aims of the application.
 The requirement specification may have to be refined as the project
develops

7. 3.Multimedia design
 What is multimedia design?
Multimedia design is the art of integrating
different media, including text, images, audio
and video to communicate with an audience.
The practice is a niche in the graphics and
website design industry

8. PROTOTYPING
 Prototyping is an experimental process where
design teams implement ideas into tangible
forms from paper to digital.
 Teams build prototypes of varying degrees of
fidelity to capture design concepts and test on
users. With prototypes, you can refine and
validate your designs so your brand can release
the right products.

9. Multimedia Presentation
 A multimedia presentation could include text, sound and
video. is this true or false? answer true or false. correct
answer = true
• Technological advancement has provided the
capability for producing exciting and readily
understood multimedia presentations.
 Types of media that can be used to enhance a
presentation are:
 graphics and photographs, illustrations and diagrams,
sound and moving images, there is no real limit to the
quality of what can now be achieved using a computer
and some multimedia software.

10. Production-Related Positions
 Audio Specialist – Music scores, sound
effects, voice overs, vocals and transitional
sounds, recording, editing and selecting
voices, sounds and music
 Computer Programmer – Creates the
underlying code that makes the website
interactive and responsive to user’s actions
 Video Specialist – Manages the process of
capturing and editing original video

11. Production-Related Positions
1. Web Designer – Develops or refines a design process
and efficiently creates a cohesive and well-planned
website from the front end
 Web Developer – Ensures the communication between
the front end of the website and its back end is working
 Web Master – Making sure the web page is technically
correct and functional on the Web Server

12. Multimedia Tools
 Multimedia authoring tools are the software
packages used to develop the elements of a good
presentation.
 There are many different computer tools and
technologies, so availability, cost, and personal
choice dictate which are used.
 A certain skill level is required to incorporate them
all seamlessly into a high quality presentation.
 Potential problematic issues are:
 Large file sizes
 Operating system incompatibilities
 Unpopular data file types

13. MULTIMEDIA
Production project

14. Overview
 Stages of a multimedia project.
 Requirements for a multimedia project.

15. Stages of a Multimedia Project
Planning and costing:
 The needs of a project are analyzed by outlining its messages and
objectives.
 A plan that outlines the required multimedia expertise is prepared.

16. Stages of a Multimedia Project
Planning and costing (continued):
 A graphic template, the structure, and navigational system are
developed.
 A time estimate and a budget are prepared.
 A short prototype or proof-of-concept is prepared.

17. Stages of a Multimedia Project
Design and production:
 The planned tasks are performed to create a finished product.
 The product is revised, based on the continuous feedback received from
the client.

18. Stages of a Multimedia Project
 Testing - The program is tested to ensure
that it meets the objectives of the project,
works on the proposed delivery platforms,
and meets the client requirements.
 Delivery - The final project is packaged
and delivered to the end user.

19. Requirements for a Multimedia
Project
 Hardware.
 Software.
 Creativity and organizational skills.

20. Hardware
 The most significant platforms for
producing and delivering multimedia
projects are Macintosh operating system
and Microsoft Windows.
 These systems provide an easy-to-use
graphical user interface (GUI).

21. Hardware
 The Macintosh as well as Windows PC offers a
combination of affordability, and software and
hardware availability.
 The Macintosh platform is better suited for
multimedia production than the Windows platform.
 The hardware platforms provided by Apple are
better equipped to manage both, sound and video
editing.

22. Software
 Multimedia software provides specific
instructions to the hardware for performing
tasks.
 Software tools are divided into production
tools and authoring tools.

23. Creativity and Organizational Skills
 In a multimedia project, being creative
implies knowledge of hardware and
software.
 It is essential to develop an organized
outline detailing the skills, time, budget,
tools and resources needed for the
project.

24. Creativity and Organizational Skills
 Assets such as graphics, sound and the
like should be continuously monitored
throughout the project’s execution.
 A standardized file-naming procedure
should be followed for precise organization
and swift retrieval.

25. Summary
 The basic stages of a multimedia project
are planning and costing, design and
production, testing and delivery.
 Knowledge of hardware and software, as
well as creativity and organizational skills
are essential for creating a high-quality
multimedia project.
