9.3 Video Streaming
The video streaming function provides the streaming of audio and video data to the net-
work without requesting the data actively with a RTSP (Real Time Streaming Protocol) or
DaVid Protocol capable client (e.g. Dallmeier recorder or PView).
Note that the format of the RTP payload to be transported must correspond with the encod-
ing standard.
For information about encoder settings see section “ Encoder Settings ” on page 42.

9.3.1 Transfer Protocol and Format
The transfer protocol defines the communication rules for the exchange of the audio and
video data in the network.
The IP packets are transferred via
uDP (User Datagram Protocol).
Note that
• UDP provides data transmission with a relatively low delay.
• packet loss (lack of images) may occur during transmission.
