This master's thesis focuses on H.264 video compression of multiple streams to be transmitted over a limited channel.
The report describes the workings of the H.264 codec. Afterwards, proposals on bitrate estimators are presented, and a predictor is chosen for later use in rate control. We design a rate controller set up as a constrained convex optimization problem, and test it against a set of video sequences.

Our results show that it is possible to encode video sequences jointly with regard to their individual qualities, whilst still keeping fluctuations in quality low.

We conclude, that if a Just-In-Time encoder is created with regard to our proposed rate controller and bitrate prediction, it could be used in realtime joint video coding.
