A solution with the receiver and then an IR transmitter stick (or even danaben place) I did not want to, but directly behind plug a cable in the IR input of the AVR.
(If the AVR already provides this possibility)
Had first experimented with this here "infrared extension IRV-200 for up to 3 HiFi / home theater devices", has worked (at first), however, he became increasingly unreliable and was therefore returned.
Then I came across this one: Wonderful !!
Made from the beginning a good impression: this power supply. voltage indication and an additional display for "function" (ie signal reception forwarding). Therefore, always clear what "happens", very nice.
I am really very satisfied!
