sending events synchronized with video stream

Question

I would like to get video stream with some real-time events synchronized with it. For example I would like to have a possibility to unlock a button, after something on the screen happenened - when something happens in front of the camera, there should be send some info about it (i.e. cameraman is pushing special button). The quest is to have this info (or event) synchronized with situation on the screen. Is it possible to send and receive such metadata using RTSP? The application will be written in WPF. I need to get functionality very similar to this one: http://www.adobe.com/devnet/flashmediaserver/articles/metadata_video_streaming.html offered by flash, but on .NET platform. Do you know any libraries that could help me? http://www.streamingmedia.com/conferences/west2010/presentations/SMWest-2010-Microsoft-Workshop.pdf JavaScript questions and answers, JavaScript questions pdf, JavaScript question bank, JavaScript questions and answers pdf, mcq on JavaScript pdf, JavaScript questions and solutions, JavaScript mcq Test , Interview JavaScript questions, JavaScript Questions for Interview, JavaScript MCQ (Multiple Choice Questions)

Answer 1

AFAIK, RTSP is not offering such a possibilty to send additional MetaData. Maybe you could put some meta data into the extension header of the RTP (video-) frames. Another way is to start a parallel meta data stream (XML i.e.). On the client side you synchronize both streams like it is done for audio/video streaming. good luck.
