I am unsure if this is the right community but here it goes.
I want to buy a smart TV and I will plug a HDMI device into it. I want to stream my games and movies to the TV via moonlight/jellyfin. I heard about ACR and how it can be used to recognize content running on our TV which will be then sold off to advertisement companies/data brokers.
Say I have isolated the traffic of the TV (the OS of the TV specifically) to a separate VLAN. But the connected HDMI device is connected to the internet. Can the TV use this network to effectively “phone home”? Do HDMI devices have this capability?
PS: I know modern HDMI dongles can also share data but I at least have the option to change the device/use a mini PC.
Agreeing with @empireOfLove2@lemmy.dbzer0.com that you’re not going to stumble into internet over HDMI between two devices. This is a zero percent concern, IMO.
Security by obsoleteness
It’s not just the obsoleteness of it, it’s the fact that any device that is on the other end of the TV’s HDMI cable would need to be actively routing internet traffic into the HDMI connection. What device would do that? Any device that’s using the TV as output for itself has no reason to also include network access.
