The Model 8656-SSB/SEB PAL-B/G
Scrambler provides dynamic
switched sync suppression, video
inversion, and drop field scrambling,
as well as data transmission for
Scientific-Atlanta’s PAL-B/G home
terminals. The unit is compatible
with all existing Scientific-Atlanta
scrambling systems.

The Model 8656-SSB/SEB PAL-B/G
Scrambler can be configured to
operate in more than 30 scrambling
modes. The scrambler receives data
transactions from the Headend
Controller and transmits the data to
the home terminals. Home terminal
control and descrambling informa-
tion is transmitted in the form of
amplitude-modulated pulses on the
audio subcarrier of each scrambled
channel. Data can be received at
either 38,400 bps or 9600 bps utilizing
RS-485 synchronous communication.

The data is encoded for increased
security. Scrambler setup and
operation is made easy by means of
a front panel, programmable
keyboard, and a 16 x 2 character
display. The scrambler can be
programmed to automatically
change from sync suppression
scrambling to video and/or sync
inversion scrambling.
