In a effort to get rid of those pesky set-top boxes provided by the cable companies, Sony and the NCTA (National Cable and Telecommunications Association) have come up with a method that would put a "cable card" directly inside TV sets . It will currently work for the 6 largest cable companies that provide 82% of cable services now.
These cards could be inserted into competing boxes, televisions or other devices to unscramble the cable signal. Of course all this depends on other electronic companies agreeing to use the same technology.
