Excelling said:Can anyone explain why MultiVision channels are clear for about 2 minutes every 10 minutes or so ??
JTA said:as far as I've read it, they change the AES key every 20 minutes. However, while sending the new key, AES is switched off and the signal is Viacess only. This can be de-scrambled by most receivers, so during this time (around 2 minutes) you can watch whatever's on. Once the new AES key has been transmitted, AES is re-activetd and Viacess is put on hold, so the image disappears again for some 20 minutes.
really frustrating, isn't is ?
