I needed Ethernet, HDR support and audio input from the receiver side back to the transmitter and then to my receiver in another room to send audio to my outdoor speakers . Pretty confusing setup, but it helped. The manual says you need cat. 6 for hdr and ethernet transmission, but with cat. 5e it also worked perfectly with the connection cable. I'm using the simpler hdbaseset AV-Access pairs for four other locations in the house, but I needed something special for this drop, which ended up working great.
