Since the first DVB-T2 services were launched in December 2009 in the UK, 2010 and early 2011 have seen services launched in Italy, Sweden and Finland. The total number of countries that have declared their intention to deploy the state-of-the-art second-generation digital terrestrial television (DTT) transmission system now stands at a remarkable 28. In the Asian region, Singapore has chosen DVB-T2 and tests have been carried out in Malaysia and Thailand.
At this year’s BroadcastAsia, DVB will be highlighting the robustness and flexibility of DVB-T2. A single DVB-T2 multiplex in an 8 MHz channel containing three Physical Layer Pipes (PLP) will be deployed for three different services: 3D and HD quality for rooftop antenna reception, SD quality for indoor antenna reception and mobile reception. The HD and SD programmes will be received in parallel on 4 television screens through commercially available DVB-T2 IDTVs as well as DVB-T2 set-top boxes. Also a DVB-T2 USB receiver will be used to receive the DVB-T2 service.
The PLP mechanism separately adjusts the robustness of each delivered service within one channel to meet the required reception conditions of reception and display devices. For example, the wide range of parameters allows DVB-T2 to address different scenarios such as HD, SD, mobile reception, indoor antenna and rooftop antenna.
For the demonstrations, The Walt Disney Company will supply 3D content. The HD and SD content and the Multiple PLP setup will be provided by Media Broadcast and the signals will be received using Humax DVB-T2 set-top box (HD-Fox T2), and a PCTV Systems DVB-T2 USB receiver (nanoStick T2). Rohde & Schwarz will supply the modulator (R&S SFU) and analyzer (R&S ETL SU 5217/3717) for the demonstration.
In addition, DVB will present transmission of several video signals in a 6 MHz channel. The 6 MHz signal will be generated by a DekTec modulator (DTU-215) and be received by a DVB-T2 STB provided by Humax. This demonstration will show that DVB-T2 in addition to 8 MHz also supports other channel bandwidths.
