Upgrading of
the TV software via IP, USB or RF. It also allows the configuration of the Auto
Update feature to enable the TV to be automatically upgraded.
Note: Auto Update feature is only available with IP or RF upgrade.
Source: “IP”,
“USB”, “RF” – This function allows you to select the Source from which the TV
Upgrade data will be received.
Note: The USB source is bidirectional (TV can read from the USB or write to the
USB), but IP and RF sources are read only.
Like the TV Clone function, the RF option requires a GNA installed in the
property head end to broadcast the data to the TVs. For more information,
contact your P&F sales representative.
Upgrade Type:
“All”, “Software”, “Assets”, “Clone”, “P:I Key”
C This section allows you to select the type of software to be upgraded to the
TV. (All 5 upgrade types are available if you select USB as source)
• If set to ALL, then all elements (Software, Assets, Clone and P:I Keys) will
be upgraded, based on their version and the version check setting.
• If set to Software, the Stand-By MCU, SPI MCU and the SOC will be upgraded.
• If set to Assets, the slideshow graphic assets will be upgraded.
• If set to
Clone, Setup menu settings and channel map elements will be upgraded.

that the correct key for its serial number is present.
Of these, only the Assets and Clone types are bidirectional. The All, Software,

additional menu item, Direction, appears.
