[QUOTE="Captain Jack, post: 1103238, member: 243342"] There's an odd feature on Premiere decoders (and only those) that allows descrambling of cut-and-rotate transmissions, similar to Videocrypt. It's different to Videocrypt as uses a different sampling rate as well as different number, and location, of cut points on screen (225 possible cuts here vs 256 in Videocrypt/Eurocrypt). It's not clear why it was implemented here and noone seems to have seen this being used anywhere. It could be similar to or even partially compatible with Smartcrypt, used on RTL9 in Luxembourg and Cryptovision used on BFBS on 27.5W and apparently cablenets in Ireland. If anyone has any video recordings of these, it would be useful to see the data there. The side effect of this feature is that it's possible to enable BOTH, line shuffling (traditional Syster) and cut-and-rotate at the same time! Here's an example: [MEDIA=youtube]Xsd1XMnaNg0[/MEDIA] This is what it looks like with just cut and rotate, without line shuffling. [MEDIA=youtube]kgb7UciqYi4[/MEDIA] [/QUOTE]
