This project aims to create an Activity to allow users to easily broadcast and stream audio and video from their webcam and microphone or their computer's display output to a classroom's central server, and share the live feed with their peers. This will be integrated into the Neighborhood View (as a "broadcast audio and video to" option or similar) to allow for most seamless sharing of broadcasts.

Since students may be interested in viewing multiple streams at once (for example, one stream showing the overall demonstration of the experiment and one showing a magnified view of a particular bacteria culture), then the interface should be able to automatically resize and tile individual streams to display them all at once while best utilizing screen space.

'''Video Sources'''

'''Audio and Video Sources'''

For the project, Webcams and X11 desktop output would be supported as video sources, and the microphone for would be an audio source. These will of course not be hard-coded into the application, but will be represented as generic "media source" plugins. For example, since this architecture could have the potential to replace the standard projector-based lecture presentation mechanism, perhaps other media formats, namely PDF lecture slides, might be supported as a future enhancement (beyond the scope of this GSoC) as well.

X11 desktop output

Icecast will be used for streaming video sources to the laptop.

'''Video Interaction'''

'''Video Interaction'''

There should be some equivalent of a "pointer" on the video broadcasting-side, for highlighting important information. There might also be a "pointer" for pointing out comments on the receiver's side, though this would probably cause more trouble and distraction in the classroom rather than promote useful feedback to the presenter, thus this probably won't be implemented.

'''Week 6'''

Since sugar-chat-activity uses Python, I will likely be using it for this project as well. The Telepathy and Farsight2 libraries will be used for implementing the multimedia chat feature.

Finish work on the client-side frontend, and integrate options to broadcast multimedia into the Neighborhood view.

Q: '''What is the timeline for development of your project? The Summer of Code work period is 7 weeks long, May 23 - August 10; tell us what you will be working on each week. (As the summer goes on, you and your mentor will adjust your schedule, but it's good to have a plan at the beginning so you have an idea of where you're headed.) Note that you should probably plan to have something "working and 90% done" by the midterm evaluation (July 6-13); the last steps always take longer than you think, and we will consider cancelling projects which are not mostly working by then.'''

In that project, the focus was on interaction of mobile Internet Tablet devices with other household electronics, such as TVs and the like, as well as the exploration of a time-centric desktop computing paradigm. However, the icecast-based broadcasting architecture there is similar (albeit far more primitive, lacking security features, and restricted to only local devices as targets) to what I aim to implement here. Having learned more about the constraints and architecture of mass-video broadcasting over Icecast, I believe I now have the necessary knowledge to deliver a production-ready implementation of the described multimedia-broadcasting activity.
