Decrypt only one channel at a time

Hello

First sry for my bad english.

I tried to create a ca filter so that only one channel decrypted at the same time.

I use oscam and have tried the following settings for the filter:
CA, ANY, ANY, "", 0, 0, ONE_TIME

But unfortunately it did not work.

Is that possible and if so, how?

Has anybody an idea?

If you're using something like Oscam you can set it there. Or limit per-user in tvheadend via Access Entries.

I'll take a look.
Thanks :)
