Viewing methods
Viewing with a plug-in
The integrated Web Server provides the simplest method.
Connect to the System via the Web and from the server homepage click on the
image that looks like video—this will give you access to the page produced by
streaming. This page has been designed to use Quick Time, which must have been
previously installed to view the video stream. Accessing the page automatically
activates audio-video streaming. The user can choose the video signal to be
displayed (Local or Automatic), which must be compatible with configured settings.
The System provides a direct link to streaming page, using the address:
http://aaa.bbb.ccc.ddd/ streamviewen.asp, where aaa.bbb.ccc.ddd is the IP
address of the System.
Viewing using an external player
Another way of viewing streaming is to use an external player. The only tested
players are QuickTime 6.0 and VIC (supplied by the University of California
Berkeley), but this does not exclude the possibility of compatibility with other
players that accept RTP streams.
The first operation necessary is to activate streaming. This can be achieved by
simply entering the IP address of the system in the "Address" field on the
streaming configuration page of the system where the player is located, or the
multicast address of the group to whom the stream is being sent. Pressing the
Activate key will enable the machine to begin the transmission of audio-video
packets to the player.
If you use QuickTime as a player, you can simply select "File" from the menu, then
"Open URL in new player" and enter http://aaa.bbb.ccc.ddd/stream.sdp where
aaa.bbb.ccc.ddd is the IP address of the System that is to send the stream.
Viewing using a Distribution Server
Distribution servers offer a range of services for stream management that the
System cannot offer directly. If users would like to make use of a distribution
server for streaming transmission sent from a System, they can do so in
accordance with the server's characteristics.
Using a Proxy
Multicast streaming transmissions require an appropriate network configuration,
with limitations imposed by the presence of any Firewall or Proxy. To offer good
protection, these must block IP packets directed to unknown ports, such as the
UDP ports used for audio and video streams. If the stream has to pass through
such equipment, the equipment must be configured for any eventual multicast and
have the appropriate ports enabled for streaming.
If the stream is sent over an internal network, problems can still arise if it is
necessary to pass through a firewall in order to gain external access.
Deactivate Streaming
In order to stop streaming, go to the Deactivate key on the streaming
configuration page and press
