Digital inequality remains a significant barrier to effective public service delivery and information accessibility in many underserved and rural regions worldwide. This study presents a Digital Video Broadcasting–Second Generation Terrestrial (DVB-T2) framework designed to enhance digital inclusion, public service accessibility, and information dissemination through affordable and spectrum-efficient digital broadcasting technology. The advocated framework integrates DVB-T2 transmission architecture with public information systems to improve communication coverage, service reach, and citizen engagement in low-connectivity environments. System performance was evaluated using parameters such as coverage efficiency, bit error rate (BER), signal-to-noise ratio (SNR), throughput, and service accessibility index. Simulation results demonstrated that the DVB-T2 framework achieved approximately 35% improvement in signal coverage, 28% increase in public information reach, and 22% reduction in communication outage compared with conventional analogue broadcasting systems. Furthermore, the framework supported high-definition multimedia transmission with spectral efficiency exceeding 40 Mb/s under optimized modulation and coding conditions. The findings revealed that DVB-T2 technology can significantly strengthen digital inclusion initiatives by providing cost- effective, reliable, and scalable broadcasting infrastructure for education, healthcare communication, emergency alerts, and e-governance services in underserved communities. The study contributes to public affairs and institutional management research by proposing a sustainable digital communication model for inclusive public service delivery.
