Digital video broadcasting-terrestrial (DVB-T) has revolutionized terrestrial television services by providing high-definition content, efficient use of frequency spectrum, and reliable coverage. Nevertheless, the first-generation DVB-T standard has some critical limitations, including low spectral efficiency, susceptibility to multipath interference, and inability to support mobile and high-capacity multimedia services. To address the limitations of DVB-T, DVB-T2 was introduced to offer advanced features such as 256-QAM modulation, LDPC coding, and MIMO systems. In this paper, a comparative analysis of DVB-T and DVB-T2 is presented, comparing spectral efficiency, data throughput, coverage reliability, and robustness against signal degradation. Based on the empirical data presented in this paper, DVB-T2 has a spectral efficiency of up to 4.7 bits/s/Hz compared to DVB-T’s spectral efficiency of 2.7 bits/s/Hz. DVB-T2 also has a data throughput of over 50 Mbps for a 7 MHz channel bandwidth, which is a 50% improvement over DVB-T. DVB-T2 also provides reliable coverage at 30% multipath distortion. Thus, the paper demonstrates that DVB-T2 completely eliminates the operational limitations of DVB-T and has the technical capabilities to meet the requirements of modern broadcasting systems. DVB-T2 has a critical role to play in future-proofing terrestrial television services.
Digital video broadcasting-terrestrial (DVB-T) has played a significant role in the global transition from analog to digital terrestrial television broadcasting, providing improved spectral efficiency, enhanced picture quality, and better resistance to noise and multipath interference compared with conventional analog transmission systems.
