In particular, royalty payments for OFDM (the basic modulation system) and MPEG 2 and\/or MPEG 4, the compression system.<\/td>\n<\/tr>\n<tr>\n<td>ISDB technology is superior<\/td>\n<td>The technical differences between ISDB-T and DVB-T are marginal.<\/p>\n<p>However, DVB-T<strong>2<\/strong> is a far superior standard. &nbsp;E.g. DVB-T2 delivers 50% more channels.<\/td>\n<\/tr>\n<tr>\n<td>There is a shortage of DVB-T set-top boxes (STBs)<\/td>\n<td>Due to delays beyond the control of broadcasters, mass production of STBs never began. Shortage of STBs was never an issue.<\/td>\n<\/tr>\n<tr>\n<td>Switching to ISDB-T would incure minimal costs. Digital transmitters would simply need to be reconfigured.<\/td>\n<td>Such a switch would require 8MHz ISDB-T transmitter equipment and STBs to be developed specifically for SA.<\/p>\n<p>An additional R2.2 billion in government subsidies would be required.<\/td>\n<\/tr>\n<tr>\n<td>Switching to DVB-T2 would incure minimal costs. Digital transmitters would simply need to be reconfigured.<\/td>\n<td>Moving from DVB-T to DVB-T2 requires that the SANS 862 spec for STBs be amended (not rewritten). This would take 3-4 months.<\/p>\n<p>Existing skills and equipment can be used.<\/p>\n<p>Existing frequency plan need not be changed.<\/td>\n<\/tr>\n<\/tbody>\n<\/table><\/div>\n<p><a href=\"http:\/\/mybroadband.co.za\/vb\/showthread.php?240598-Digital-TV-standards-The-truth\"><strong>Digital TV standards<\/strong><\/a> &lt;&lt; comments and views<\/p>\n","protected":false},"excerpt":{"rendered":"<p>DVB-T, DVB-T2, ISDB-T.
