Before that I was under the impression that the satellite only received and did not transmit... (I DON'T have the phone line plugged into it- and never have).
Thats not how satellite works....
Although they "Love" to use obfuscation of how the technology works, the basic are simply that it "has" to have an "uplink"..
Oldest models were modem based for the smart card to be read as to what PPV channels you accessed and paid for, was reset every month, now they use the uplink to send the data by burst transmission on an alternate carrier wave in the KU band (was originally the old C band)...
Think of it this way..
The uplink is the "return" signal for a connection to the satellite in geosynchronous orbit around the planet..
The "strength" of the signal is rated by .db, lower rating indicates a "less then perfect" alignment of the dish, higher rating is better usually around 90 to 95db is optimal, but I have seen 100db before..
This is a "constant link" it does not get shut down anymore when you put the box into "sleep mode" because you are not really turning it off, it's just deactivated certain circuits in the box for transmission to the TV. There is "still" a transmission..
Most of the time it's just a carrier signal in the low priority setting known as a "transponder" signal, it lets the satellite "maintain" a loopback signal between you, and the satellite itself, if this was not the case, then it could take up to a minute or more for the signal to achieve a loopback, between you and the satellite for TV viewing, so you end up staring at a blank screen for over a minute before you can watch TV if the uplink was not maintained at it's basic level as a transponder signal...
So at night, when you have put the box into "sleep mode" ( intentionally mislabeled as off), they send a "wakeup" signal to the box, that puts it in "wake mode" which allows them to download, and upload data from the days activities..
They monitor everything you do, the channels you watch, the actual programs you watch, what you have in the DVR if you have one, and will duplicate this in their back end database, for data mining purposes.. even the schedules you keep in the box, are recorded in a burst transmissions to either main headquarters, or the data mining site they have..
It was not just for high speed internet they switched over to the KU band, it was for a much more personal and complete invasion of your privacy it was done for..
It's all automated now, so "smile" and bend over, with every push of that button, you truly "ARE" being watched...
