TAILIEUCHUNG - DVB-NGH for next-generation digital broadcasting

Next generation broadcasting can be made compatible with today's ATSC DTV tuners and achieve the desired spectrum efficiency and interoperability with wireless broadband. | DVB-NGH For Next-Generation Digital Broadcasting I don t see how next generation broadcasting can be made compatible with today s ATSC DTV tuners and achieve the desired spectrum efficiency and interoperability with wireless broadband. Doug Lung Mar 6 2012 Since I wrote last month s article on Next Generation Digital Broadcasting I ve been researching what other countries are doing to meet the need for a new broadcast platform that meets consumers demands for broadcast content anywhere anytime on any device. I don t see how next generation broadcasting can be made compatible with today s ATSC DTV tuners and achieve the desired spectrum efficiency and interoperability with wireless broadband. Ideally the system should be able to cover use cases from fixed reception on larger screens in home with or without an outdoor antenna and small screens smartphones or tablets for example in the home in the office in cars on trains and wherever these devices are likely to be used. ADDING NEW FEATURES TO DVB-T2 I first looked at DVB-T2. This technology incorporates many of the desired features and its Future Extension Frame FEF provides the opportunity to add new features. However I found DVB-T2 was not originally designed for use with mobile handheld devices. That capability can be provided through the FEFs as has been done with DVB-T2-Lite a less complex version of DVB-T2 designed for use with smaller devices. The BBC has conducted tests if DVB-T2-Lite transmitted along with two HDTV program streams on a DVB-T2 signal. See references at the end of this column . Release of the DVB-T2 standard produced in June 2011 extends the DVB-T2 base standard by adding a mobile profile. Additional improvements are planned for DVB-NGH Next Generation Handheld . DVB-NGH specifications are expected to be published by the DVB project early this year. It provides a robust transmission platform based on DVB-T2 and the necessary protocols to allow interoperability with wireless broadband .
