Abstract
The digital terrestrial television (DTTV) transmission based on digital video broadcasting-terrestrial second generation (DVB-T2) for a single frequency network (SFN) shall be studied. The DTTV signal performance is very important. Therefore, the performance of DTTV should be studied. SFN is a key factor in DVB-T2 technology due to the benefits of SFN. In order to evaluate the DVB-T2 performance, this research had investigates broadcasting reception threshold of DVB-T2 signal. The experiment was done in a laboratory of Mass Communication Organization of Thailand company, Thailand, and field experiment was done in urban area of Sing Buri, Thailand. The measurement model was set up to measure the the DTTV performance parameter with respected to guard interval delay time of two SFN transmitters. The acceptable result of minimum power, received signal, CNR, MER, and transmission loss are presented. The reliability of the result was validated by using polynomial. The measurement results provided a useful information for optimization and modeling of DTTV broadcasting for SFN system with DVB-T2 in Thailand.
