55
Port
This parameter contains the number of the UDP port where audio packets are to be sent. Since the
streaming content is RTP, data are sent to four different ports: one port for audio, one port for video
and two ports for the RTP information corresponding to both streams. Therefore, starting with an
audio port number, it is implied that the audio data will be sent to this port number, video data will
be sent to the audio port number plus two, and the odd port numbers before and after the video port
will be used for RTP data. For example, if the audio port number is 554, the port number for video
will be 556, and the port numbers for RTP data on both streams will be 555 and 557.
TTL/Hops
This parameter contains the value for the Time to Live associated with multicast packets.

Streaming activation/deactivation request.
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, wich 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.
