I guess you might be thinking of sth. like this or this

This little guy's web server and mDNS responder could provide the discoverability, and wake up the TV set (they have GPIOs) from standby when a connection request comes in. They have SPI interfaces, so some 12 to 16 Mbit/s should be possible. Of course you can share the RJ-45 pins between this and a full blown PHY/MAC to get the Gigabit or whatever you build in.

So in summary: yes, it is possible to have a web server and mDNS responder running (to make it discoverable) while the TV set is in standby. When the TV set is woken up by a connection request, the full app would start and do the authentication etc.

Just my two cents anyway.

Thanks a lot and cheers,
