(DBS) A new method of program delivery by which signals are sent directly to small (18-inch to 3-feet diameter) home dishes form high-powered (120- to 200-watts per transponder) Ku-band satellites, as opposed to "over the air" broadcast, cable delivery or lower-powered C-band or Ku-band transmissions. PrimeStar is a quasi-DBS service, while USSB and DirecTV, planned for 1994, and ExpressVu, planned for 1995, will be true DBS services.
