Abstract

The advanced compatible television (ACTV) system is a proposal for the single-channel transmission of widescreen enhanced-definition television (EDTV) images. A widescreen high-definition source is encoded into a signal that is NTSC-compatible. Existing NTSC receivers display a selected 4:3 portion of the widescreen image with standard NTSC resolution. A new widescreen receiver is proposed, tuned to the same 6 MHz RF channel, that displays a widescreen image with a resolution in excess of 400 lines/picture height in both spatial dimensions. The encoding process is reviewed and the recovery of various signal components to produce the widescreen image in the ACTV receiver is discussed
