Scan Tuner for Available Channels
The Scan Tuner section (FIG. 64) is used to scan all of the frequencies used by the broadcaster and detect all of the available TV
(and optionally Radio) channels.
NOTE: The DVB system does not support the decoding of encrypted channels, therefore encrypted channels are not added to the
channel list when they are detected.
Perform these steps to scan for available channels on all frequencies:
1.
Enter the multicast address of the tuner to scan.
2.
Enter the port used by the tuner multicast in the Port text box.
3.
Choose whether to scan for Radio Channels as well as TV channels. Select Yes for the setting Include Radio Channels to
include radio channels.
4.
Click Start. Vision

begins to scan for available channels. Any channels it finds appear in the Select Channels to Transmit table.
Transmit Selected Channels
This section describes how to transmit DVB Tuner channels on your network. Users can view these channels in the Live Channels
menu, or from set-top boxes attached to your system. The process is as follows:
1.
In the Select Channels to Transmit Table, click the check box in the Multicast column for the channels to transmit. This channel
will now be added to the list of Live Channels that can be viewed by PC or Set-top box users. Repeat this step for each channel
to multicast. To stop transmitting a channel, just click again to deselect the check box. The channel will be removed from the
list of Live Channels.
NOTE: If using one of AMXs DTV-TX transmitters, all programs in the stream may appear in the TVCT table for your transmitter device
even when the transmitter is configured to only stream certain channels.
Channel To Transmit Table
On the right of the page is a table containing a list of TV (and optionally Radio) channels available from the selected Tuner. This
table contains the following information:
NOTE: If configuring a firewall on Vision2 servers, incoming multicasts must be permitted.
