I know that after the deadline in Feb. 2009 all OTA viewers will need to have digital TV sets or converter boxes, but how will that affect cable viewers? Will cable channels have to be digital as well? Will we still be able to use older cable ready sets, or will cable viewers also have to get converter boxes for older TVs? Or will digital broadcast channels be converted to analog? Will digital subchannels be required to be carried by cable systems as well? Also, how will this affect satellite TV? I want to set an antenna to get local digital TV, but I know that a lot of my viewing will still be cable. Any ideas? Thanks!
