Mini Project: The Mighty Boosh

Multicast streaming system

A simple kamaelia based system to multicast stream programmes. Aiming to stream carousel(s) to clients containing 1/2 hour programme episodes (pre-recorded, pre-compressed to files)

System consisting of:

• playout system
• client 'tuner' application

Target schedule

Highly aggressive schedule to see what can be done in a short space of time. Expected to actually take a little longer.

• Mon 11th July 2005 - Project start
• Wed 13th July 2005 - code written
• Mon 18th July 2005 - testing begins

Achieved Schedule

Multicast Carousel work completed:

• Friday 15th July 2005

Basic client side tuner interface completed:

• Friday 15th July 2005

Simple Reliable Multicast Protocol completed:

• Tues 19th July 2005

Server pipeline:

CRON (MH) Done

• system cron, eventually to be a 'component' cron, probably a combination of both for a while
• determine shape of text file 'scripts' for component cron

DATA SOURCE (MH) Done

• improved file reader. sequence of files to read coming from a new CHOOSER component, separate out bitrate limiting

SERVER (MS) Done

• Provide factory interface for MH to do testing (wasn't necessary/needed)
• Bypassed - MH used an basic alternative.

INTEGRATION

• In progress

Client pipeline

• Implementation of more robust Simple Reliable Multicast protocol.
• Took longer than anticipated due to boundary conditions in the sending side.

• Over optimistic for such a short time frame. Currently reviewing approach.
• VLC will happily take data on stdin on linux, so let's do that /first/
• restreaming locally
• must be turned into threaded component

Client player (eg. VLC, not our responsibility)

• receiving locally restreamed HTTP
