“Streaming Management”
Allows modifications of the Announcements, Video, Rate, Address, Port, and TTL/Hops
parameters by external applications (from the Web, for example). If this option is not
selected and a unicast IP address is present in the “Address”, then only the system identified
by that IP address will be able to view the stream.
• Enable all addresses: this option allows modifications to the previously mentioned
parameters by almost any external system. If this option is not selected, then you can
establish which system or subnet is enabled to perform this operation. If the mask is
255.255.255.255, then the system will be selected, if the mask is 255.255.255.0 then the
subnet will be selected.
• Password: allows password protection of streaming management
“Enable Streaming”
Allows stream viewing according to the limitations imposed by the parameters “Streaming
Management” and “Enable all addresses.” If this option is not selected, streaming will never be
activated.
Announcements
This drop-down menu allows you to choose how the System will notify the user that an external
system has requested streaming activation.
Options:
• Activation: The System will display a dialogue box containing a warning and a video
camera icon that will stay in place as a reminder for as long as streaming is active.
• Status: Only the video camera icon will be displayed during streaming.
• Confirmation request: A dialogue box will appear to request confirmation of
streaming activation. This option offers an extra level of protection.
Video
This drop-down menu allows you to choose which video signal is transmitted when streaming is
active.
If the “Automatic” option is selected, the streaming content will be determined by the status of the
terminal: if the terminal is connected (in either a point-to-point or multipoint session), video coming
from the remote site will be streamed. If the terminal is disconnected, local video will be streamed.
If the “Local” option is selected, the system will always stream local video.
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).
