AXIS 241Q/241S - Video streams
MPEG-4 protocols and communication methods
To deliver live streaming video over IP networks, various combinations of transport
protocols and broadcast methods are employed.
• RTP (Real-Time Transport Protocol) is a protocol that
allows programs to manage
the real-time transmission of multimedia data, via unicast or multicast.
• RTSP (Real-Time Streaming Protocol)
serves as a control protocol, to negotiate
which transport protocol to use for the stream. RTSP is thus used by a viewing
client to start a unicast session, see below.
• UDP (User Datagram Protocol) is a communicati
ons protocol that offers limited
service for exchanging data in a network that uses the Internet Protocol (IP). UDP
is an alternative to the Transmission Control Protocol (TCP). The advantage of
UDP is that it is not required to deliver all data and may drop network packets
when there is network congestion, for example. This is suitable for live video, as
there is no point in re-transmitting old information that will not be displayed
anyway.
• Unicasting is communication between a single se
nder and a single receiver over a
network. This means that the video stream goes independently to each user, and
each user gets their own stream. A benefit of unicasting is that if one stream fails,
it only affects one user.
• Multicast is bandwidth-conserving technology
that reduces bandwidth usage by
simultaneously delivering a single stream of information to multiple network
recipients. This technology is used primarily on delimited networks (intranets), as
each user needs an uninterrupted data flow and should not rely on network
routers.
AXIS Media Control (AMC)
The recommended method of accessing live video (MPEG-4 and/or Motion JPEG) from the
Axis video server is to use the AXIS Media Control (AMC) in Microsoft Internet Explorer in
Windows. This ActiveX component is automatically installed on first use, after which it
can be configured by opening the AMC Control Panel applet from the Windows Control
Panel. Alternatively, right-click the video image in Internet Explorer.
How to stream MPEG-4
Deciding on the combination of protocols and methods to use depends on your viewing
requirements, and on the properties of your network. Setting the preferred method(s) is
done in the control applet for AMC, which is found in the Windows Control Panel. When
this has been set, AMC will test all the selected methods in the specified order, until the
first functioning one is found.
