Implement Video Mixing for directshow application

Ours is a encoder client --> media server --> video viewer application. Which works similar to other video streaming applications like u#[login to view URL] (remove # to read correctly). it works flawlessly and supports many simultaneous streams. Todo: if in encoder I select "channel name" as a common phrase like "1" and I do that in 4 different encoders...(please note that channel name is a new field to be added on encoder)...so if the server finds 4 encoder streams from different sources with same channel name...it will mix those streams (it will be like 4 quadrant for example) and make available one mixed stream ([login to view URL]) to the viewers...so if viewers choose to view [login to view URL] then it will show mixed view of all the streams together. ...but the difference will be it will be using 1/4 of bandwdith at viewer end because it is 1 mixed stream instead of 4 individual streams To be given: Complete working source code to compile and run on VS 2008. Source code in vc++ & c#. Deliverable: compiling and running application with source as per the requirements.
