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
OK, or simply close the browser.
