HDTV (High-Definition Television)HDTV (High-Definition TV) is probably the biggest breakthrough in television broadcasting since the advent of color TV. It is a digital TV broadcasting format that transmits wide-screen pictures and Dolby audio with more detail and quality than analog television, or other digital television formats. Types of High-Definition TV displays include direct-view, plasma, rear screen, and front screen projection. While it is possible to see the lines on a standard television screen, HDTV lines are not at all noticeable even though the fine-grained HD picture contains five times more information than does the standard television picture as well as multi-channel CD quality sound. The difference in video and sound quality is truly dramatic. The most prominent distributor of High-Definition TV is DIRECTV. DIRECTV uses its wireless satellite network to distribute High-Definition content as oppposed to coaxial cable or copper wires. Because DIRECTV does not use terrestrial media to transmit its HD content, it costs DIRECTV less than a cable company to provide service. That savings is passed on to DIRECTV customers in the form of lower subscription rates and installation charges. |
