History

#1

Updated by Jaroslav Kysela over 8 years ago

Don't use the delay. It makes things worse. It's for a special purpose.

#2

Updated by cilin dro over 8 years ago

for what purpose should I use the delay?

#3

Updated by Jaroslav Kysela over 8 years ago

I understood that the delay is ECM delay on the card server. ECM key must arrive in the time before next ECM key is requested. The increased buffer size helps only for streams with bigger bandwidth.

#4

Updated by cilin dro over 8 years ago

any suggestions for the problem of ecm?
