Description
RTP over UDP
Real-Time Transport Protocol, using UDP transport, lessens
network delay and is required for two-way audio streams.
RTP over RTSP (TCP)
Real-Time Transport Protocol, using TCP transport, guarantees that
data is delivered and that no packets are dropped, but some
network delay may occur.
RTSP over HTTP
A standard solution to help RTSP work through firewalls and Web
proxies, so that viewers behind a firewall can access RTSP streams.
MJPEG over HTTP
Consecutive JPEG images are sent individually over HTTP.

transmitted to multiple clients.
