1 INTRODUCTION

1.1 Background

The project involves development and deployment of an online portal that streamsvideoto subscribers. Video files will be stored in a third party hosting company ANDAPs SERVER. The portal will have user authentication based on subscribinginstitutions (MEMBER) and their profiles and purchase history. The AP(AccessPortal) administrator (ADMIN) will have the ability to manage the content, i.e.cataloguing the video files hosted by the third party hosting firm.

1.2 Purpose of the Document

This document describes in details the design of the Video Streaming Software module. Theprocess flow and detailed design specifications are illustrated in this document.

The activities as per the current scope are as follows:

Creation of a role based User Management System which will help manage users ofdifferent levels

Upload, study and watch the videos of several categories, manage video catalogueand class consisting of students of several institution

1.3 General requirements

Actuate requires that the new system possesses the following attributes:

System must be able to handle large volume of visitors

System must be extendable so that new modules can be added in future

1.4 Objectives of the System

The objectives of the system is to

1. Manage activities of users of the system with different access levels

2. Enable students from different institution as well as individual students to play andwatch videos
