ECG068/0798 WHITE PAPER (cont.) 2...0 RTSP RTSP stands for "Real-Time Streaming Protocol." It is a higher-level client/server protocol for controlling the efficient delivery and quality of service of a multimedia stream along with controls such as stop, pause, rewind, fast-forward, etc. It also contains provisions for security as well as for usage measurement and rights management so that streaming content providers can control and charge for the usage of their streaming content. RTSP can be used with a variety of IP delivery methods including UDP, TCP, and IP Multicast. It also supports the use of RTP as an underlying protocol. RSVP RSVP stands for "Resource Reservation Protocol." Its purpose is to provide consistent quality of service by guaranteeing a maximum allowable transmission delay for streaming packets along with the ability to prioritize specific packet streams. It does this by requesting the dynamic allocation of bandwidth from the network much like PC applications dynamically allocate memory for applications.
