Abstract
A television set includes an integrated receiver decoder. By integrating the receiver/decoder with the television, some circuitry and memory are shared. Moreover, a digital video signal provided by the receiver/decoder need not be converted to an analog NTSC signal before transmission to the television CRT. In one embodiment, where a television having a 16.times.9 aspect ratio is used, on-screen display data is displayed without distortion.
