Transmission method Description
JPEG/HTTP Static JPEG image transmission. Refer to the JPEG tab
below.
MJPEG/HTTP A series of consecutive JPEG images, the Server Push –
multipart/x-mixed-replace method. Refer to the JPEG tab
below.
RTSP + RTP/UDP RTSP with separate RTP/UDP audio and video streams.
Supported both for audio (G.711) and video (H.264, H.263,
MPEG-2 and MJPEG). Refer to the RTSP tab below.
RTP/RTSP RTP tunnelling via RTSP. Supported both for audio
(G.711) and video (H.264, H.263, MPEG-2 and MJPEG).
Refer to the RTSP tab below.
RTP/RTSP/HTTP RTSP tunnelling via HTTP. Supported both for audio
(G.711) and video (H.264, H.263, MPEG-2 and MJPEG).
Refer to the RTSP tab below.
RTP/UDP-Multicast Uncontrolled RTP packet multicast. Supported for audio
(G.711) only. Refer to the Multicast tab below.
Explanation of Terms
RTP(Real-Time Transport Protocol) – is a protocol defining the standard packet format for
audio/video transmission via IP networks.2N IPintercom 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 IPintercom 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 IPintercom 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. The2N IPintercoms
are ONVIF compatible and fully implement the ONVIF Profile T and Profile S.
JPEG– is a standard method of lossy compression of images.
