15 Preventing Pro:Idiom Key Loss
There are two mechanisms which may cause Pro:Idiom key loss in some commercial television
sets that have been identified to us by LG
Unapproved mapping or remapping of PIDs
Off air (OA) ATSC receivers may use PIDs which conflict with PIDs in use in Pro:Idiom
licensed systems.
External EdgeQAMs may map or remap PIDs in violation of the Pro:Idiom (P:I) licensing
agreement.
Other unapproved digital video equipment may also use PIDs which conflict with P:I
licensed equipment.
TV set power on sequencing design problems
A very small number of TV set models are known to have power up sequencing issues that
cause the Pro:Idiom licensed decryptors to operate improperly. The manufacturers of these
sets have taken strong corrective action measures to update them. Contact your specific set’s
manufacturer for details.
15.1 PID Mapping at the COM46 Receiver
Pro:Idiom PIDs are in a protected range
Channel 1 AUDIO PID = 0x30
PID remapping at the edgeQAM
Pro:Idiom PIDs have been remapped and overlap with Audio PIDs on other channels
