The evolution of digital broadcasting technologies has significantly enhanced the efficiency, reliability, and quality of television signal transmission. DVB-T2 (Digital Video Broadcasting - Second Generation Terrestrial) represents a major advancement over its predecessor, DVB-T, offering increased data capacity, improved spectral efficiency, and robustness against interference and multipath effects. This technology enables broadcasters to deliver high-definition television, interactive services, and mobile reception with greater flexibility and cost-effectiveness. Complementing DVB-T2, the DVB-X2 class of standards extends the digital broadcasting framework by encompassing a broader range of transmission methods, including satellite (DVB-S2), cable (DVB-C2), and future terrestrial enhancements. DVB-X2 standards share a unified design philosophy emphasizing higher throughput, enhanced error correction, and scalability, facilitating seamless integration across various distribution platforms. This paper reviews the technical foundations, key features, and practical applications of DVB-T2 and the DVB-X2 family, highlighting their impact on the broadcasting industry and their role in shaping the future of digital media delivery.
