Abstract
Fast startup for streaming media includes one or both of a technique for predictive start and a technique for switching delivery channel(s) during streaming. Predictive start allows a media content source to predict which media stream(s) are desired by the requesting client device and begin streaming those predicted media stream(s) to the client device. The delivery channel switching technique allows the media content source to begin streaming the media stream(s) using one delivery channel (e.g., using the Transmission Control Protocol (TCP)), and then check whether another delivery channel (e.g., using the User Datagram Protocol (UDP)) will work and switch to that other delivery channel if it will work.
