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.

研究用于单频网络（SFN）的基于数字视频地面广播第二代（DVB-T2）的数字地面电视（DTTV）传输。DTTV信号的性能非常重要。因此，应研究DTTV的性能。由于SFN的优势，SFN是DVB-T2技术的关键因素。为了评估DVB-T2的性能，本研究调查了DVB-T2信号的广播接收阈值。该实验是在泰国泰国大众传播组织的实验室中进行的，现场实验是在泰国信武里市区进行的。建立测量模型以相对于两个SFN发射机的保护间隔延迟时间来测量DTTV性能参数。最小功率，接收信号，介绍了CNR，MER和传输损耗。使用多项式验证了结果的可靠性。测量结果为泰国采用DVB-T2的SFN系统的DTTV广播的优化和建模提供了有用的信息。
