You will have to use a RF link amp to send the picture and you can only send analogue pictures to link rooms. If you already have RF link amp, feed the apple tv into BV7 Mkiii via component. This should work as you are converting the digital out from apple tv into analogue via component. If this does not work there is a convertor which you can buy. Search on the forum for this you will find it here as this topic has been raised before.
