Explanation of Terms
RTP(Real-Time Transport Protocol) – is a protocol defining the standard packet format for
audio/video transmission via IP networks.2N IPintercom employs this protocol for
audio/video streaming. The RTP transport protocol is either UDP or also RTSP and HTTP.
RTSP(Real-Time Streaming Protocol)– is a network protocol for streaming server
control (controls setting up, launching and stopping of audio/video streams).
HTTP(Hypertext Transfer Protocol)– helps transmit practically any contents and is
used primarily by internet browsers for web server communication.2N IPintercom uses
the HTTP to transmit static JPEG images or MJPEG streams via the HTTP Server Push.
IP Multicast– is a way of parallel sending of IP packets from one source to multiple
stations via IP networks.2N IPintercom uses IP multicast for sending and receiving audio
streams.
ONVIF (Open Network Video Interface Forum)– is a set of video camera search,
configuration and administration specifications for the IP network. The2N IPintercoms
are ONVIF compatible and fully implement the ONVIF Profile T and Profile S.
JPEG– is a standard method of lossy compression of images.
