Streaming Management
In this menu the System can be configured to use streaming. This technology allows viewing of and listening to live or
recorded events by a large number of users connected to the IP network without the need for a large file to be downloaded. It
is based on the continuous transmission of data compressed by particular programs (systems) from a server, then decoded at
the client side by an appropriate player that works even during data buffering, thereby avoiding long delays.
The System is able to transmit to networks in either unicast or multicast. If the streaming is unicast, only one client at a time is

The System is able to transmit to networks in either unicast or multicast. If the streaming is unicast, only one client at a time is
allowed to connect to the stream. If it is multicast, there is no theoretical limit to the number of connected clients.
In case of pre-recorded event streaming, replay a recording of the event using a VCR or DVD player connected to the System

RTSP (Real Time Streaming Protocol), nor can it provide unicast streaming to multiple clients, or offer other services typical of
distribution servers.

Menu options are "Streaming Management," "Enable Streaming," and Activation.
“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.

“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:
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.
