well i think thats what he means by cable/satellite
however his HDTV option is redundant, as they still require cable or satellite (or most have a built-in digital receiver, same as those converter boxes) and most or all SDTVs produced recently have built in converters as well (mine does)
The point is he is saying that HDTV will soon be mandatory. It won't, pure and simple. Only those channels on satellite or cable that are advertised as HD will be HD. Other digital channels are not HD, they are digital SD.
Furthermore there will be no requirement for a converter box for anyone with cable as many channels will still be sent over the cable plant in plain old analog format that old TV's will be able to use same as always.
If one gets their signal over the air, ie. via an antenna on the roof, then they will need either a new TV or a converter.
If one wants those channels available on cable that are only sent in digital format then one will need a digital cable receiver just as they do now. Anyone with a digital cable box already will not have to swap it out for a new one.
For those on satellite there will be no change at all. Those signals have been all digital for a long time now already.
The author is wrong , not all channels will be HD, and not all channels on cable will even have to be digital.
So, if the author is refering incorrectly and simply means digital TV, rather than the subset of HDTV, and there is a mind control system that will use digital TV signals somehow, then it could have been in place more than a decade ago and affected everyone with digital cable or DTH satellite.
If the author is correct and the converter box will be able to put this mind control system into effect via the analog o/p and using the old NTSC TV set then the system does not actually need the digital transport to be effective.
THUS, this is all make-believe and further evidence of the lack of technical understanding that the general populace has.
