Rate. This drop-down menu allows you to choose the bandwidth occupied by
audio and video streaming. Note that if a rate of 64K has been selected, the
video will not be transmitted, because all the bandwidth will be occupied by
audio.
Address. This parameter contains the IP address for the stream. If this field
contains a unicast IP address, it will be automatically overwritten by the IP
address of the system that has requested to view the stream from an HTML
page supplied by an internal web server. By pressing the Active key on the
configuration page, you can activate streaming: the system will start the
transmission of audio and video packets to the selected IP address.
If the IP address is multicast, streaming will be sent to a multicast group
identified directly by the IP address, enabling viewing by a large number of
users (theoretically unlimited).
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.
