Does the IPTV support hardware via USB?
How would you control routing of data to if1 rather than if0?
You could email them and ask them if this device is supported and would work.
Does your IPTV have a USB 3.0 port?
If not, then you will be limited to max less than half Gig-E speeds.
(and, your IPTV would also need to support network connections over the USB)
You can certainly try it and see what you get!
I have that adapter (the Plugable brand, but same chipset) and use it for my MBP. I prefer it over the Thunderbolt-to-Gigabit adapter from Apple. The one problem you will run into is the USB adapter needs to have a driver installed for the OS to recognize it. I am not familiar with IPTV devices. Do you have a GUI to an OS where you can install a driver?
@GPap: I'm not sure you'll achieve what you're looking for through those means. Practical example:
A Bluray film can be said to be about 25 GB in size, and about 2 hours long.
25 gigabytes = 200 gigabits
2 hours = 7200 seconds
That means that on average, the computer in a bluray player will be loading data from the disc at a rate of 200/7200=0,02 gigabits per second, or 20 megabits per second. In other words, if you want to stream a Bluray-equivalent data stream to your TV, there's something terribly wrong with your home network if a (supposed) 100 Mbps link seems insufficient.
Nope, you're probably right there. But the problem isn't the network, so making that part better won't help you at all. What would happen if you forgot all about the decoder in the TV and ran media streams through a dedicated media player? A Raspberry Pi can be had for cheap, and along with a media center distribution like OSMC does a good job of playing pretty much anything you can throw at it. If that isn't enough, you'll probably have to build or buy a HTPC of some sort (I suspect a base-model Mac Mini will do a superb job if you run Kodi or VLC on it..)Thank you, 100 Mbps it is sufficient but my IPTV has H264 encoder inside and compresses the stream into 6,5 Mbps quality. I would like more quality and it seems that I cannot do anything for this.
