Conditional Access SCG 1-240
Multiplexer
Use this field to set the index of the multiplexer function associated with this scrambling
control group. A value of
0
indicates this SCG is inactive.
Crypto Period
This value sets the
suggested
crypto period for this scrambling control group. The actual
crypto period is negotiated at connection to an ECMG.
ECM
System Index
This value is the index of the CAS entry associated with the ECM. Use this value to identify
the appropriate ECMG to attach ECM.
Service ID
This assigned service ID is typically is the program number in the transport multiplex.
AC Index
This value sets the access criteria index for this ECM. A value of
0
(the default setting)
specifies that the access criteria should be generated automatically.
ECM PID
The value in this field sets the PID for this SCG ECM. The value must be unique across all
PIDs in the multiplex.
Encryption Mode
This parameter selects BISS or Simulcrypt encryption. With encryption operating, a program
can be scrambled and passed over an insecure medium to an authorized decoder, which
can unscramble the stream. If
None
is selected, the encryption process is disabled, so the
multiplexer provides unscrambled output.
When
BISS
is selected, encryption is enabled. This option directs the multiplexer to use its
BISS SW
(session word) to scramble the output MPEG stream. A decoder will need the
session word in order to decrypt the stream. For details, see
