Moved your post to a better area.
Yes, this is just a very small Freeview receiver with built-in scart plug. They usually have a separate "eye" which you position somewhere towards the front of the TV so that you can use a remote control with it.
I'm not too sure but I think that some might even be able to take their 12v power from the scart socket - this would certainly cut down on cables.
Apart from that I think you might find them a bit too lacking in features.
