There is an estimated 600 million television sets dispersed throughout the world and about 70 percent of them are color. (Kuhn, 2001: 1). A significant and precarious matter is whether the modern criterion of HDTV should be attuned with existing, color TV standards, succeed the existing standards, or be concurrently transmitted with the accessible standards (with the conception that the existing standards would obliterate over time).

High Definition Television is any system developing vitally enhanced picture resolution than that of the usual 525-line (625-line in Europe) television monitor. Digital HDTV systems, by dissimilarity, broadcast pictures and sounds in the arrangement of digital data. These numerical data are transmitted, utilizing the identical high radio frequencies that contain analog waves, and computer processors in the digital television system that then decipher the information. Digital HDTV can transmit sharper, clearer images and sound with very diminutive interferences or other flaws. Of more significance, digital television systems will apparently be adept to send, store, and influence pictures as well as receive them, thus combining the functions of the television set and the compute...
