Creating an Interactive Timeline for Viewing Multimedia Streams

Problem
One paradigm we are investigating for viewing classroom notes is a timeline interactor. For example, take a look at the interface for notes for this quarter's 6751 class. This current interface is done as pure HTML, and it has limitations. The purpose of this project is to create a more interactive and powerful timeline for viewing multiple streams of information. This timeline should be written in Java and provide the ability to filter out various streams of information (e.g., show only the Liveboard slides, or show audio keywords and URLs, etc.) and it should be able to control various commercial multimedia streaming products like RealAudio or RealVideo and VXtreme. Background

• The program that generates the 6751 interface was written by Janak Bhalodia, a CS undergrad. Dr. Abowd and Janak can give you access to this program and talk about what you should try to produce.
• We have examples of how to link to RealAudio, RealVideo and VXtreme, so you should take a look at what we have for that. In addition, you might want to look into the programmability of the plug-in controls that these products advertise. Your project will basically want to replace the controls of those projects, so you will want things like start, stop, etc.
• You will be writing this as a Java and will need to be able to write something that runs a clock.

• You will need to produce a mock-up of the timeline controller that you show to Dr. Abowd before you begin coding anything.
• You should turn in a Web page that contains a description of your system, has pointers to all available code (including pointers to any systems you build on top of).
• This Web page should also contain a pointer to a demonstration of your timeline controller, working on either the data from a given Classroom 2000 class or some other similar information.
