o CI MULTIDECYPT MODE:
 CombinedPMT: convert the PMTs of all selected programs together
 MultiPMT: convert PMTs of the selected programs to corresponding
o CI Bitrate Mode: Set the max output bit rate of the CAM.
 BISS (Basic Interoperable Scrambling System): is a satellite signal scrambling
system developed by the European Broadcasting Union and a consortium of
hardware manufacturers. There are two types:
o BISS-1, transmission are protected by a 12 digit hexadecimal "session key"
that is agreed by the transmitting and receiving parties prior to transmission.
The key is entered into both the encoder and decoder, this key then forms
part of the encryption of the digital TV signal and any receiver with
BISS-support with correct key will decrypt the signal.
o BISS-E (E for encrypted), is a variation where the decoder has stored one
secret BISS-key entered by for example a rights holder. This is unknown to
the user of the decoder. The user is then sent a 16-digit hexadecimal code,
which is entered as a "session key". This session key is then mathematically
combined internally to calculate a BISS-1 key that can decrypt the signal.
o
BISS-E ID, an identification ID given prior to transmission and reception.
Usually a standard CAM can support Max. 72Mbit data processing unless it
has instruction for higher bit rate support. Selecting a wrong CAM output bit rate will
cause video mosaic issue because the actual processed data exceeds the CAM Max
handling capability.
3.4.2.10 System
to a CAPMT and then send this CAPMT to CAM for processing. This
setting is in order to let the IRD work more compliantly with some
special CAMs. If the CAM can't decrypt programs normally, user can
try to select this option.
CAPMT respectively, and then send each CAPMT to CAM module
for processing. This is the default setting.
