I don't understand your point. My local Time Warner cable company delivers nearly 70 analog TV channels to this day in analog format. Are you referring to some cable companies which are purely digital?

It seems to, but if you have a cable box (STB) then they send digital
signals to the STB which converts to analog for your "consumption."


Not necessarily. My TimeWarner cable box which provides the 'latest' 1080p HDMI HDTV service on the "digital" channels also tunes and down-converts standard analog broadcasts for the lower 68 channels I receive. If you look at the cable spectrum with a spectrum analyzer, you will see traditionally spaced 6 MHz analog channels with traditional audio carriers at 4.5 MHz, color bursts at 3.58 MHz, and a traditional single sideband (VSB) video signal.

In fact, a nearby paging service which operates in the normal VHF high-band 160 MHz range will often come on the air to do paging, and their signal strength is strong enough here that the classical beats and herring bone which we ham radio operators call "TVI" (television interference) are produced. This would never happen if the originating analog signals had been converted to digital before being put on the cable wire as a modulated signal.

My point really was / is that analog transmission from the cable company front end to the consumer RF input jack still exists, at least in some cable systems, even when a new vintage STB is employed. Time Warner is actually "bragging" in their local ads that the February 09 FCC mandate will not adversely impact their customers, and are encouraging people who lack newer ATSC tuner-equipped TVs or converters to drop their off the air reception and switch to their cable system.
