The TV will take care of any analog to digital conversion that may be needed. You will probably not get high definition so the picture will look pretty lousy. If you have a cable box then connect it to the TV with the best av connection that the box and TV share. If you don't use a box then connect the cable to the RF input and run the TV setup and select analog cable if available as a choice (if not try the other options and run the channel scan and see what you find). If you have over the air digital TV available then I would suggest you try an antenna to get an HD picture.
