【 摘 要 】

Digital television (DTV) is a new television service representing the most significant development in television technology since the advent of color television in the 1950s. DTV can provide sharper pictures, a wider screen, CD-quality sound, better color rendition, and other new services currently being developed. A successful deployment of DTV requires: the development by content providers of compelling digital programming; the delivery of digital signals to consumers by broadcast television stations, as well as cable and satellite television systems; and the widespread purchase and adoption by consumers of digital television equipment. A key issue in the Congressional debate over the digital transition has been addressing the millions of American over-the-air households whose existing analog televisions will require converter boxes in order to receive digital signals when the analog signal is turned off.
