Sly card kill signal

[lotuselite]

What form does the signal to stop decoding the channels you no longer subscribe to take? Is there any way to stop this signal getting to the card in cccam?

A Entitlement Control Message (ECM) is sent to the stb to tell it how to unscramble
a channel, it is not as simple blocking this, a control word is also sent as part
of the ECM and that tell the stb to unscramble that word is changed about
every 10 seconds therefore you can't just block ECM once channel unscrambles.

Sorry reread your post I think that in the old days if you stopped the telephone connection
to stb that seemed to do the trick but I don't know if this still works.

I'm sorry I am a noob so don't understand. Does the ecm decide which channels are decoded? I thought it was something to do with emm.

Re: Sly card kill signal

Both ECM & EMM are for the card itself. EMM's are management messages to the
card, they arrive at irregular intervals which can vary from every few minutes to
every few months depending on what the messages are managing, typically
they allow key updates. EMM's effectively manage the behaviour and decryption
of ECM's. Both are important for the proper functioning of the card.

Every 10 seconds, on Sky GB and SKY IT , i guess that it's even 5 seconds sometimes.
Or i have a bad dsl connexion, but when i'am on these channels, sometimes the signal drop in less than 5 seconds.

The signal is an emm which deletes the keys from the card. It doesn't "kill" the card. It removes the keys, but with the correct emm it's possible to write the keys back to the card - e. g. when you subscribe the channels again.

Some receivers have the possibility to block the emms so that the keys are still on the card. But the most systems have a time-counter on the card so that you can use them for a few days or weeks, but then it's over.

Re: Sly card kill signal

I had a sly card in a spiderbox and it lasted 6 weeks after being cancelled before being turned off

Sky_de has the same 6weeks-counter on the cards.
But then it's finished because MOSC is no longer possible since a few years.

If I interpret correctly the emms change my entitlements, which are dated some days after my subscription is due to expire, and I can continue to descramble until that date. Or will I be sent a special emm on the last day which will change the dates?

The keys on the card are "refreshed" regulary every two or three days in the subsciption time. So when it ends (normaly last day) no more refreshing-emms and then the deleting-emm comes. So when you receive the last refresh, the six weeks begin.

Re: Sly card kill signal

and then the deleting-emm comes.

so I need to block the deleting emm?

[Satphoenix]

Re: Sly card kill signal

Yes, block all emms beginning at the last day. And of course for the next 6 weeks.
When the counter is down - blackscreen.

Re: Sly card kill signal

when signal become weak it means data signal become weak so ecm dont go to card
i dont think have negative effect in card. as i know mistake ecm cause fail card

[Satphoenix]

Re: Sly card kill signal

...as i know mistake ecm cause fail card

I think this is not possible.
An emm is a complete command for the card (with a checksum included).
If the emm is not correct, you have a checksum failure and the card does nothing, if the checksum doesn't fit.

Re: Sly card kill signal

Sorry to jump in but if i,m getting 0ecm on a cccam does this mean that this channel is getting blocked or is it no output by provider ??
