Payview III about hacktv

[fsphil]

The official documentation would be nice, but yes that'll almost certainly still be a secret (or just filed away in storage and forgotten). In some cases the documentation written by people trying to hack the system is enough. A working decoder would be nice too as I'm reluctant to add scrambling modes that can't be used on real hardware.

According to McCormac's Black Book, it's a random line inversion system with a very high video bandwidth compared to Astra. The encoding scheme apparently involves superimposing a high-amplitude high-frequency signal on top of the baseband video. I suspect that variant may only have been used on cable systems.

Regardless -- details of a pirate decoder can be found here: http://www.geocities.ws/ResearchTriangle/9405/tc.htm and it seems to be described in patent GB2042849A: https://patents.google.com/patent/GB2042849A

There's also a later version of Payview which is described in EP0341801A2, which is more in line with the system described on Wikipedia: https://patents.google.com/patent/EP0341801A2/
McCormac briefly mentions this later system in the Black Book, pointing out that the pirate decoders were microprocessor based and periodically needed EPROM updates.

Going by Google, it's also described in one of McCormac's books, "World Satellite TV and Scrambling Methods: The Technicians' Handbook" -- https://www.amazon.co.uk/World-Satellite-Scrambling-Methods-Technicians/dp/0917893190 -- though I expect this may be to a similar level as the Black Book covers it.

Any documentation would be helpful. Any television signals can be created using HackTV but they have to be defined and more importantly physical decoder/attached cable box must exist and recognize these signals.

lemme guess... hacktv can actually manipulate signals as they're being transmitted?

[Zcooger]

HackTV is ran by a single command, if you want to change any parameters you have to close it manually and start with new arguments. Of course it can generate ANY signals you define.

Nice.

For your last comment regarding documentation... I'm positive it's probably a safe-guarded secret [and probably still is]. This would be fine.. if I had video footage.

[justaconsumer]

I see.

Checking the biggest Swiss auction site for "Teleclub-Decoder" yielded 0 results on both ricardo.ch and eBay.ch.

I dunno why there are no boxes on auction but my only solution for this is to wait for any videos of Payview to surface, let alone any documentation. If there is a auction for such boxes or documentation someone found and told me about, I might bump this.
