Commercial HDTV services have become a reality and HD broadcasts are now commonplace.  <\/p>\n<p align=\"justify\">HDTV is not new and HDTV broadcasts have been going on in the USA and Japan for a number of years. However, what was lacking was an inter- nationally agreed standard. Europe did not enter the HDTV market till recently and that delay was utilised to reach an agreement on a unified standard. The first step was to agree to a common interface format (CIF) for HDTV. HDTV is invariably associated with digital television, and altho- ugh this is not necessarily the only way it can be delivered, without the processing capabilities of digital technology, HDTV would be impractical.  <\/p>\n<h4 align=\"justify\">Why HDTV?<\/h4>\n<p align=\"justify\">The two most prominent television systems, PAL and NTSC produce a moving picture with a quality referred to as standard definition (SD). While picture quality using SDTV is very good and has served television users very well over decades, it does suffer from noticeable degradation in quality in large size displays. To keep up with customer expectations and maintain picture quality, higher picture definition, i.e. high resolution must be used. The following summarises the advantages of HDTV:  <\/p>\n<p align=\"justify\">\u25cf HDTV offers a step change in picture quality, delivering a home view- ing experience similar to that offered in cinemas.  <\/p>\n<p align=\"justify\">\u25cf Viewers will see greater depth and tone of colours and textures. The improved clarity of HDTV broadcasts will bring an even greater sense of excitement and drama to a wide range of programme genres.  <\/p>\n<p align=\"justify\">\u25cf HDTV can provide more than four times more data on a display screen than a SD broadcast. This is because of the increased picture resolution that HD broadcasts deliver and HD display devices will be able to receive.  <\/p><div class=\"tgfqh6a0dbc3e4f2c1\" ><script async src=\"https:\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js?client=ca-pub-0778475562755157\"\n     crossorigin=\"anonymous\"><\/script>\n<!-- 300x600 television-and-video -->\n<ins class=\"adsbygoogle\"\n     style=\"display:inline-block;width:300px;height:600px\"\n     data-ad-client=\"ca-pub-0778475562755157\"\n     data-ad-slot=\"6549443290\"><\/ins>\n<script>\n     (adsbygoogle = window.adsbygoogle || []).push({});\n<\/script><\/div><style type=\"text\/css\">\r\n@media screen and (min-width: 1201px) {\r\n.tgfqh6a0dbc3e4f2c1 {\r\ndisplay: block;\r\n}\r\n}\r\n@media screen and (min-width: 993px) and (max-width: 1200px) {\r\n.tgfqh6a0dbc3e4f2c1 {\r\ndisplay: block;\r\n}\r\n}\r\n@media screen and (min-width: 769px) and (max-width: 992px) {\r\n.tgfqh6a0dbc3e4f2c1 {\r\ndisplay: block;\r\n}\r\n}\r\n@media screen and (min-width: 768px) and (max-width: 768px) {\r\n.tgfqh6a0dbc3e4f2c1 {\r\ndisplay: block;\r\n}\r\n}\r\n@media screen and (max-width: 767px) {\r\n.tgfqh6a0dbc3e4f2c1 {\r\ndisplay: block;\r\n}\r\n}\r\n<\/style>\r\n<div class=\"tmmrk6a0dbc3e4f1f4\" ><script type=\"text\/javascript\">\n\tatOptions = {\n\t\t'key' : '0c1eb4c533eaedb7b996f49a5a4983a9',\n\t\t'format' : 'iframe',\n\t\t'height' : 300,\n\t\t'width' : 160,\n\t\t'params' : {}\n\t};\n<\/script>\n<script type=\"text\/javascript\" src=\"\/\/www.highperformanceformat.com\/0c1eb4c533eaedb7b996f49a5a4983a9\/invoke.js\"><\/script><\/div><style type=\"text\/css\">\r\n@media screen and (min-width: 1201px) {\r\n.tmmrk6a0dbc3e4f1f4 {\r\ndisplay: block;\r\n}\r\n}\r\n@media screen and (min-width: 993px) and (max-width: 1200px) {\r\n.tmmrk6a0dbc3e4f1f4 {\r\ndisplay: block;\r\n}\r\n}\r\n@media screen and (min-width: 769px) and (max-width: 992px) {\r\n.tmmrk6a0dbc3e4f1f4 {\r\ndisplay: block;\r\n}\r\n}\r\n@media screen and (min-width: 768px) and (max-width: 768px) {\r\n.tmmrk6a0dbc3e4f1f4 {\r\ndisplay: block;\r\n}\r\n}\r\n@media screen and (max-width: 767px) {\r\n.tmmrk6a0dbc3e4f1f4 {\r\ndisplay: block;\r\n}\r\n}\r\n<\/style>\r\n\n<p align=\"justify\">\u25cf Availability of multi-channel audio and surround sound.  <\/p>\n<p align=\"justify\">\u25cf Widescreen as standard.  <\/p>\n<h4 align=\"justify\">HDTV common interface format<\/h4>\n<p align=\"justify\">An ITU-R BT.709 standard provides three different specifications for HDTV: 720\/50<i>p<\/i>, 1080\/50<i>i <\/i>and 1080\/50<i>p<\/i>.
