[net.video] Satellite scrambling

Referring to an article on pg. 11 of ELECTRONIC ENGINEERING TIMES, issue
371, March 3, 1986:

  The BLACK BOX SOLUTION company claims it has cracked the MA/COMM Video-
cypher II technology for decrypting satellite video transmissions. Current
users of the Videocypher II technology are HBO and Cinemax Pay TV service,
while other services such as Showtime, Disney, Movie Channel, etc. are
planning to follow suit by scrambling transmissions in the near future.
  BLACK BOX representatives were recently at the conference of Society
for Private and Commercial Earth Stations (SPACE) selling manuals which
detailed how to descramble THE VIDEO PORTION ONLY for a price of $49.95.
Due to implications of legality of decryption devices they DID NOT have
any working hardware at the conference. An estimated cost of building the
descrambler circuitry is approximately $90-$100 in components. They also
claim that their method of descrambling also allows other formats such
as the OAK and ORION formats currently used by X-rated pay TV services
and Canadian satellite broadcasts to be descrambled also.
  Please note however that while this method descrambles the video portion
of the picture, THE AUDIO IS STILL SCRAMBLED. BLACK BOX claims that by 
late March they will have the audio solution worked out and will have
manuals available for $24.95.
  BLACK BOX states: "The use of the BLACK BOX solution to decode scrambled
TV signals may be illegal. We do not encourage anyone to violate federal
law or FCC regulations". In marketing of the solutions BLACK BOX claims
them as "educational tools" for persons seeking technical information on
the subject of TV scrambling. BLACK BOX is working with a local parts
supplier, BTW Electronics, to provide component kits for less than $90.00.
  The Address and phone number of BLACK BOX SOLUTIONS Co. is:

	The Black Box Solution
	4014 Central Ave.
	Hot Springs, Arkansas
			71913
	(501) 321-1845

  Yes, I own a satellite dish and NO WAY will I purchase a videocypher II
box and then pay a cable company for monthly program service!!! I would
really like to see someone prove that I'm using an illegal decoder box
as they would need to have a court order for search & seizure to even get
into my home. And I damn well know a judge won't sign one unless there is
reasonable grounds to do so!!!

Teltone Corp., or even of my own as I just spilled a cup of coffee
down my keyboard and it's been doing weird things!!!  :-)

Fat chance.  The Videocypher II uses a quite simple method for scrambling the
video signal, but the audio is encoded by the DES encryption method, with the
encryption key being changed very frequently.  The audio encoding will remain
secure for quite a while (until someone steals the keylists from M/A-COM).
