iCOMPEL Digital Signage - User Guide (V8.1.1)
A "second with no signal" is a full second in which there is no decodable signal available. These generally indicate that the
aerial has been unplugged. The last no signal error time is the time of the last reported second with no signal.
A transport stream discontinuity is a sign of poor signal; it indicates that there have been parts of the stream lost in
transmission. Discontinuities may show up on receivers as glitches or dropouts in the picture, or squeals in the sound.
Settings
When the rebroadcaster is disabled, the TV card is available for the iCOMPEL to use as normal, and no stations are
rebroadcast by this iCOMPEL. When it is enabled, the TV card is not available for the iCOMPEL to use (thus Analog TV,
Digital TV & Radio, composite capture and S-Video capture are not possible), but one Digital TV or Radio station may be
streamed over IP multicast.
The only setting you will normally need to change is the Digital TV or Radio station. Select the station you wish to stream
from the list - if the station you wish to stream is not present, return to the Digital TV & Radio Settings page and rescan.
The stream name is included in SAP announcements; other iCOMPEL players with a Streaming feature key installed will
offer this channel in their list of streaming channels. The default is to use the station name as found in the tuning data, but
you may set this to a custom name if you wish; for example, you could set it to "iCOMPEL TV" to allow all Layouts to refer
to the same channel, regardless of what you configure here.
Advanced Settings for Network Administrators
These properties can only be modified if the User Interface Policy is set to Detailed. Please visit the Options page to set
this mode.
The SAP announcement address is the address this iCOMPEL sends details of the streaming channel to. The default of
224.2.127.255 is specified in the SAP standard; iCOMPEL players with the Streaming feature key are shipped with this
address configured.
The multicast destination is specified as a multicast IP, UDP port and multicast TTL. The default multicast IP is generated
from the iCOMPEL serial number, within the organization-local space; change it if it conflicts with other multicast devices.
Similarly, the default UDP port of 4900 has been chosen to reduce the number of conflicts you will see. If another device
uses the same multicast IP and port number as this iCOMPEL, streaming is corrupted; if the multicast IPs match, but the
port numbers are different, the receiving iCOMPEL will have reduced performance, but will still function correctly.
The default TTL of 31 is supposed to limit itself to your site only. It can be changed as needed to fit in with your multicast
routing.
9.4.7 International settings
This page allows you to choose language and country preferences for the screen output.
These are used by the HTML player to provide a preferred language and locale to websites and by the text clock to
determine the locale appropriate date and time formats.
Note This is different from the language and localization settings of the Web page user interface, which are determined
by the browser settings.
9.5 Backing up your Player
Use the Backup & Restore page to create Backup files (on a USB storage device) that contain all the media content and
settings from the iCOMPEL.
These Backup files can be stored and later restored onto this iCOMPEL or another.
To create a Backup file:
1. Insert the USB storage device on which you wish the Backup file to be created.
