We ordered both phone, internet and cable service. A tech came out and wired up all the jacks and placed round filters at the service entrance all except for the line that the cable modem is on. Just out of curiosity I removed those filters a short time after we had it installed and was able to get all of the premium channels (HBO, Encore, Starz etc...) but not PPV.
How exactly does the system work on a digital system? Do these filters need to be placed somewhere between the head end and the customers home to filter out non-paid service or can the system work without them and rely on the cable box to do as its told from the head end?
What do these filter do exactly and why do they need to isolate them on a customers service entrance or utility distribution hub? Why not just filter it from the head end?
