What the FCC means when they say you can subscribe to cable TV with an analog TV, or that the TV would not be affected by the over-the-air change to digital TV, is that the cable company will "solve" the "problem" of having a non-digital TV. The most likely way the cable company will do that is to give you a cable box. The cable box will have an NTSC channel-3 output. The signal going into the box may be analog, digital, or a mix. In many places, you can still get some number of NTSC channels on cable TV, and tune them directly with a cable-ready analog TV without a cable box, but this option is steadily going away.

To refine the answer to your question about using boxes, if you hooked up that Teknika box (or a Jerrold or other NTSC cable box), you would only get the same NTSC channels you would on a cable-ready NTSC TV, provided that your cable company still has some analog channels available.
