Dear Fadi,

Thanks for suggesting me SteamCoders RTP.NET for unicast transimission of data. But i am having trouble using this library. I couldn't fully understand it. I have so many questions in my mind.

Q1: I have tried to run a simple standalone application. When the application starts it created one session, one sender, and one receiver. Then it creates there partilipitants on three different ports on the same machine. Then it adds the newly created partilipitant to the sender and the receiver that we have created earlier. After creating and adding all three participitants, it adds the sender and receiver to the session. What I understood after reading the documentation of RTP.NET that one session can have multiple Sender/Receiver and one Sender/Receiver can have multiple participitants. Am I understood right?

Q2: Now according to RTPParticipitant.Send() method description RTPPacket will be sent to RemoteEndPoint that was specified in that particular participitant constructor. RTPSender.Send() method will send RTPPacket to all the participitants of this RTPSender and RTPSession.Send() method will send RTPPacket to all the participitant of this session. In these three Send option only first one works as we are defining the RemoteEndPoint for sending Packets. The other two options gives error "Requested address is not valid in the context". How we can use the other two options as I think it can help in multi casting or broadcasting?

Q3: I could only see two Receive methods associated with Participitant and Session classes with there particular scope. Could you please help me on that as well?

Q4: In the above mentioned example session, sender, receiver, participitants are on same local machine. In Client/Server scenario how RTP Session will work. How a participitant created on client machine will be added to the session created on the server machine?

Q5: If you can provide any sample of this RTP.NET lib or related work. Could you please share them with me?

Looking forwards to your response.
Thanks,

Atif
