The logos that you see on your unit come from the providers server. Channel logos can easily be found at LyngSat. I use that to identify what the International channels that don't currently have a name. With that being said from time to time they will rotate with channels hence why there isn't a stable name yet... but I see it more as a place holder for something in the future. The main proposed channel list never had channels in the 600/700's or anything above 999.
