Online TV Music
2MIN504 - Commercial Environments
Miguel Rodrigues Student Number: 11511645
• The project consists of an online TV music channel which content
can be broadcasted online with a computer or a mobile device like
Apple iPhone or the new phone from google Android G1
• The channel will broadcast Video clips from unsigned bands, as well
as festivals and other music events from 3 capitals of Europe:
London, Lisbon and Madrid. As well interviews from the artists.
• For the content to be broadcasted the user needs to install first a
plug-in (i.e. Preferably our own plug-in but we can use other plug-ins
such as sopcast, TVU Networks, Veetle Networks and so on)
• The artists can submit the files through a submission form in .mp4 or
.mov movie file formats and they will be converted to our own video

Note: It is very important to understand what and how to communicate to each of the key
stakeholders, making them feel confortable with the project and how it is progressing.

• Adopts a structured, rigorous, project led approach to the development of
data structures and processes (fail to recognise that data structures are
largely stable and many processes dynamic)
• requirements will not change during the development of a project
•Following each step of SSADM rigorously can be time consuming and
there may be a considerable delay between inception and delivery (which is
typically the first time the users see a working system).
Unified Modeling Language
modeling syntax aimed primarily at creating models of
software-based systems, but can be used in a number of areas.
Features of UML Methodology:
Syntax only - UML is just a language
It is a generic modeling language and needs to be
adapted by the user to particular applications.

3. Empowered teams with authority to make decisions.
5. A focus on frequent delivery of products.
7. Using suitability for business purpose as the essential criteria for acceptance
5. Iterative and incremental development to ensure convergence on an
accurate business solution.
13. Reversible changes during development.
15. Requirements that are base lined at a high level.
17. Integrated testing throughout the life cycle.
9. Collaboration and cooperation between all stakeholders.

It is possible, during the implementation of the plug-in and, mainly, on the development of the new Video
