Videos obtained by the
RTSP are decoded and displayed using an H.264 decoder.
In the first stage, a destructive tsunami crossing the Indian ocean from an earthquake source near the Makran Trench will be simulated by international notifications from the Regional Tsunami Providers (
RTSPs) of Australia, India and Indonesia to designated Tsunami Warning Focal Points in each country.
At this point the encoded bit stream is pushed to the
RTSP server for packetization and streaming.
To transport the contents, RTP on UDP is used, but to control playback,
RTSP protocol messages [18] are used; this protocol has different types of messages that tell the system what action the user wants to execute on playing multimedia content (pause, play, forward, rewind).
Some of them are designed to initialize and control the streaming session (RTCP,
RTSP and SDP), another protocol was created to transfer data from the payload, and this is known as RTP.
In addition the SVS-8 supports unicast and multicast streams, as well as the RTP, RTCP,
RTSP, SAP, TCP and UDP protocols, among others.
