Figure 4.20: BISS Mode Selection Window
Note
All session words, injected ID and Encrypted session words cannot be read back and are not echoed
back to the display. These values are also not stored in the profiles but will be reused after a power
cycle. To comply with the specification the keys cannot be changed more than ten times in a 5-minute
period and that there is a minimum of 10 seconds between changes. The keys are transmitted in the
clear via the GUI so should be used with caution, perhaps by setting the Injected ID up only on the
front panel and never via the GUI.

4.8.2
BISS is fully disabled and the transport stream will be unmodified. If BISS is subsequently enabled
then the modification in the transport stream may cause a momentary glitch in the video. It is
preferable to use BISS-0 which will modify the transport stream without decrypting the video.
BISS-0
4.8.3
The transport stream will not decrypt in this mode but is modified to remove signalling about BISS.
In this mode decryption can be enabled seamlessly.
BISS-1
4.8.4
The transport stream is decrypted using the session word which is a 12 digit hex value. If the key is
not present then the last entered value will be used. This session word is independent from the
key generated when using BISS-E and will be retained.
