Information regarding voice and video transfer over Network

Question

Hi folk , recently i just finished my major project with dealt with HTTP protocol and complex data transfer over TCP/IP with numerous clients and the application is running pretty good any ways i was actually hoping to add a video and audio streaming feature to an already developed application in C#. Video and audio streaming  is completely new to me , however i have worked with the VFW(Video for windows) API to interact with the connected webcam in your application. I heard for Audio and video stream you need to familiarise yourself with the RTP protocol ?? How different is it from the TCP/iP protocol and are there any good books or resources available to accomplish this task in C# thanks??
