Digital Video Broadcasting-Second Generation Terrestrial (DVB-T2) Framework for Enhancing Digital Inclusion, Public Service Accessibility, and Information Dissemination in Underserved Regions

Introduction

Transition from analog to digital broadcasting has become a major global initiative aimed at improving spectrum efficiency, enhancing transmission quality, and expanding access to information services [1-3].Among various digital broadcasting standards, Digital Video Broadcasting–Second Generation Terrestrial (DVB-T2) has emerged as one of the most advanced terrestrial television broadcasting technologies due to its superior spectral efficiency, higher data throughput, enhanced signal robustness, and support for high-definition and ultra-high-definition content delivery [4-6]. Adoption of DVB-T2 has significantly transformed the broadcasting landscape by enabling transmission of multiple television and data services within the same bandwidth previously occupied by a single analog channel [7-9]. This advancement is particularly important in underserved and remote regions where access to reliable information remains limited due to inadequate communication infrastructure, geographical barriers, and economic constraints [10-12].

Digital Inclusion and Socio-Economic Development in Underserved Regions

Digital inclusion has become a fundamental driver of socio-economic development in the twenty-first century, as access to reliable information and communication services increasingly determines participation in education, healthcare, governance, and economic activities [13-15]. Governments, international organizations, and communication stakeholders widely acknowledge that equitable access to digital infrastructure is essential for improving service delivery in critical sectors such as remote learning, telemedicine, disaster response coordination, smart governance, and transparent public administration [16], [17,18]. In this context, digital connectivity is no longer regarded as a supplementary service but as a foundational requirement for sustainable development and societal integration [14,15].

Despite significant global advancements in communication technologies, next-generation wireless systems, and network expansion initiatives, a substantial proportion of the population in rural and underserved regions continues to experience limited or unreliable access to digital services [17-19]. These disparities are primarily driven by inadequate infrastructure deployment, high installation and maintenance costs, challenging geographical conditions, and low commercial viability for private network operators [20,21]. Studies on terrestrial propagation further confirm that environmental variability significantly impacts service quality and coverage reliability in such regions [13,20].

Persistence of this inequality poses serious implications for sustainable development, as communities with restricted access to digital services are often excluded from timely public information, education, healthcare, and economic participation platforms [2-4]. Consequently, growing demand exists for cost-effective, scalable, and resilient communication frameworks capable of delivering essential services to populations underserved by conventional broadband and mobile communication infrastructures [17,14,5].

Digital Inclusion and Access to Public Services

Digital Video Broadcasting–Second Generation Terrestrial (DVB-T2) provides strong potential for improving digital inclusion and public service delivery due to its wide-area coverage, efficient spectrum utilization, and reliable transmission performance. Unlike broadband systems that require high infrastructure investment, DVB-T2 supports cost-effective one-to-many broadcasting, enabling simultaneous delivery of educational content, public announcements, emergency alerts, healthcare information, agricultural support, and government communications to large populations [13-15].

Its effectiveness in underserved regions is linked to robust propagation characteristics and efficient path-loss behavior in UHF bands, which support reliable reception under diverse environmental conditions [16,17]. Studies confirm that terrain, vegetation, and atmospheric variability significantly affect terrestrial broadcasting performance, making accurate planning essential for coverage optimization [13,16]. These attributes position DVB-T2 as a practical solution for reducing information inequality between urban and rural populations [18,19].

Advances in communication technologies further enhance DVB-T2 capabilities. Artificial intelligence enables adaptive spectrum management and context-aware optimization in wireless networks [20], while intelligent reflecting surfaces improve signal propagation in obstructed environments [4]. In addition, machine learning techniques enhance signal estimation and resource efficiency in OFDM-based systems similar to DVB-T2 [5].

The broader evolution toward 6G and hybrid communication architectures highlights integration between terrestrial and non-terrestrial networks for universal connectivity [6,7,4]. UAV-assisted and satellite systems further extend coverage to remote areas, supporting resilient communication infrastructures [8,9]. Consequently, research increasingly focuses on intelligent and adaptive broadcasting frameworks that improve coverage efficiency, reduce deployment costs, and ensure equitable access to public services across diverse regions [10,11].

Research Gap, Aim, and Objectives

Despite significant advances reported in the literature, several research gaps remain evident. Existing studies have largely focused on propagation modeling, wireless communication optimization, artificial intelligence, 6G technologies, satellite systems, UAV communications, and signal processing techniques. However, limited attention has been devoted to developing a comprehensive DVB-T2 framework specifically designed to enhance digital inclusion, public service accessibility, and information dissemination in underserved regions. Furthermore, existing research rarely integrates coverage optimization, accessibility enhancement, service delivery efficiency, and socio-economic inclusion objectives within a unified broadcasting framework. The absence of such an integrated approach limits the ability of policymakers, regulators, and network operators to maximize the developmental benefits of digital terrestrial broadcasting infrastructures.

Therefore, this study aims to develop a Digital Video Broadcasting–Second Generation Terrestrial (DVB-T2) framework for enhancing digital inclusion, public service accessibility, and information dissemination in underserved regions.

To achieve this aim, the study pursues the following objectives:

• Examine the role of DVB-T2 technology in improving digital inclusion within underserved regions.

• Evaluate factors affecting public service accessibility through digital terrestrial broadcasting systems.

• Investigate the influence of network coverage characteristics on information dissemination effectiveness.

• Develop an integrated DVB-T2 framework that supports efficient and inclusive communication service delivery.

• Provide recommendations for optimizing DVB-T2 deployment strategies for sustainable digital inclusion and public information accessibility.

The successful realization of these objectives is expected to contribute to the advancement of digital broadcasting technologies and support broader efforts aimed at reducing information inequality, improving public service delivery, and promoting socio-economic development in underserved communities.

Materials and Methods

DVB-T2-based broadcasting framework was developed in this study, integrating adaptive scheduling, multiplexing, modulation control, and single frequency network (SFN) synchronization to enhance digital inclusion, public service accessibility, and information dissemination in underserved regions. System performance was evaluated using coverage efficiency, bandwidth utilization, transmission reliability, and Digital Inclusion Index metrics.

DVB-T2 System Architecture Methodology using Mathematical Modeling

DVB-T2-based framework was developed to enhance digital inclusion, improve public service accessibility, and strengthen information dissemination in underserved regions. The methodological design adopts a multilayer broadcast architecture that integrates content generation, signal processing, transmission, and reception processes into a unified end-to-end communication system. The framework conforms to established DVB-T2 standards and incorporates adaptive prioritization mechanisms to improve the efficiency and reliability of public service broadcasting. Advanced modulation, channel coding, multiplexing, and coverage optimization techniques were embedded within the system to ensure robust signal delivery, efficient spectrum utilization, and extended service reach in geographically dispersed and infrastructure-limited environments (see Figure 1).

Mathematical Model 1: System Transmission Model

This model represented the aggregated received signal as the convolution of transmitted content streams with channel effects under additive noise conditions. The Content Generation Layer was implemented to produce and classify multiple categories of public service content, including educational programs, emergency alerts, governance communication, and health advisories.

Figure 1: DVB-T2-Based Methodological Framework for Enhancing Digital Inclusion, Public Service Accessibility, and Information Dissemination in Underserved Regions

Emergency content was given the highest priority, followed by public safety information, educational programming, governance updates, and general entertainment content. This classification ensured that critical information was transmitted with minimal delay and maximum reliability, particularly in underserved regions.

Mathematical Model 2: Priority Scoring Function

Where:

• P(ci) represented the overall priority score,

• Si represented service importance,

• Ei represented emergency weighting,

• Ii represented inclusion impact,

• α,beta,gamma represented weighting coefficients.

The Encoding and Multiplexing Layer was applied to convert raw multimedia content into DVB-T2-compatible digital streams using MPEG Transport Stream (MPEG-TS) encoding. The encoded streams were then combined using DVB-T2 multiplexing techniques to form a single high-capacity transmission channel. This process optimized spectral efficiency and ensured that higher-priority services received proportionally greater bandwidth allocation. The multiplexing process was dynamically adjusted based on network load and content priority. The scheduling algorithm initialized an empty transmission queue into which content streams were inserted according to descending priority order. For each incoming content stream, a utility-based efficiency score was computed to evaluate the ratio between public service value and required bandwidth resources. This approach ensured that highly beneficial content requiring lower transmission bandwidth was prioritized for scheduling efficiency. The final scheduling score was computed by combining priority and efficiency metrics, after which all content streams were sorted before queue allocation.

Mathematical Model 3: Spectral Efficiency

Where R_b denoted bit rate and Btotal represented total available bandwidth. This expression quantified the efficiency of spectrum utilization in the DVB-T2 system. The Modulation and Transmission Layer was implemented using Orthogonal Frequency Division Multiplexing (OFDM) to improve robustness against multipath fading and channel distortion. Forward Error Correction techniques, including LDPC and BCH coding, were applied to enhance transmission reliability. Adaptive modulation schemes such as QPSK, 16-QAM, 64-QAM, and 256-QAM were dynamically selected based on real-time Signal-to-Noise Ratio (SNR) measurements to maintain optimal trade-offs between robustness and throughput.

Mathematical Model 4: Adaptive Modulation Decision Rule

Adaptive modulation control was incorporated into the scheduling framework to improve transmission robustness under varying propagation conditions. The modulation scheme was dynamically selected based on regional Signal-to-Noise Ratio (SNR) measurements. Lower SNR conditions triggered the use of robust modulation schemes such as QPSK, while higher SNR conditions enabled higher-order modulation schemes such as 64-QAM and 256-QAM to maximize throughput and spectral efficiency.

This function ensured that modulation schemes were dynamically adapted to channel quality variations.

The Single Frequency Network (SFN) configuration was deployed to synchronize multiple transmitters operating on the same frequency. This approach eliminated inter-frequency interference and improved coverage uniformity across wide geographic regions. Time synchronization mechanisms were implemented across all transmitters to ensure constructive signal combination at the receiver end. The SFN structure significantly enhanced signal reliability in rural and underserved regions.

Mathematical Model 5: SFN Signal Combination

The Single Frequency Network (SFN) synchronization process was subsequently applied across all transmitters operating within the DVB-T2 framework. Synchronization timestamps were aligned to ensure constructive signal reinforcement and minimize inter-symbol interference. This process enhanced signal stability and improved reception quality across underserved geographic regions characterized by difficult propagation environments.

Where xk represented the signal from transmitter k, and τk represented propagation delay. This model described the synchronized summation of transmitted signals.

At the Receiver Layer, DVB-T2-compatible devices such as digital televisions, set-top boxes, and community viewing centers were used to decode broadcast signals. The received signals were demodulated, error-corrected, and converted into audiovisual content accessible to end-users. This layer ensured that users could access essential public service information without requiring internet connectivity, thereby enhancing digital inclusion in underserved regions.

Mathematical Model 6: Digital Inclusion Index

The Digital Inclusion Index (DII) was continuously updated throughout system operation to evaluate the effectiveness of the presented DVB-T2 framework in enhancing accessibility and public service dissemination. The index incorporated population coverage, accessibility level, and service reach metrics to quantify overall inclusion performance. This metric enabled the system to assess the societal impact of broadcast scheduling decisions in real time.

Where C represented coverage, A represented accessibility, and S represented service reach. This index quantified the effectiveness of the DVB-T2 framework in achieving inclusive information dissemination.

Overall system performance was evaluated using key metrics such as signal quality, spectral efficiency, bit error rate, and coverage probability. These metrics were used to assess the effectiveness of the proposed DVB-T2 framework in improving public service delivery and enhancing digital inclusion in underserved regions.

Mathematical Model 7: Content Stream Representation and DVB-T2 Scheduling and Prioritization Algorithm

The DVB-T2 Scheduling and Prioritization Algorithm was implemented to dynamically allocate broadcast resources based on content importance, bandwidth availability, and digital inclusion objectives. The algorithm was designed to support efficient dissemination of emergency alerts, educational programming, governance communication, and entertainment content while maintaining optimal spectral efficiency and coverage reliability. A queue-based scheduling framework was adopted in which all incoming content streams were evaluated according to predefined priority classification rules before transmission. The scheduling mechanism continuously monitored network conditions, including Signal-to-Noise Ratio (SNR), network load level, and available DVB-T2 bandwidth resources, to ensure adaptive and context-aware content allocation.

Where:

• C represented the complete set of broadcast content streams,

• c_i represented an individual multimedia content item.

The input parameters used within the scheduling framework included the total available DVB-T2 bandwidth, required bitrate per content stream, utility score, network load condition, and Digital Inclusion Index weighting factor. These parameters were continuously updated during operation to ensure efficient bandwidth allocation and adaptive scheduling decisions. Emergency and public safety broadcasts were assigned the highest scheduling priority, while governance and educational services were assigned medium-to-high priority levels. Entertainment content was allocated lower transmission precedence to preserve bandwidth resources for socially critical information services.

Mathematical Model 8: Efficiency Function

Where:

• E(ci) represented transmission efficiency,

• U(ci) represented utility or public service value,

• R(ci) represented required bitrate.

Mathematical Model 9: Final Scheduling Score

This equation was used to rank all content streams before bandwidth allocation.

Mathematical Model 10: Bandwidth Allocation Constraint

After sorting, the algorithm sequentially allocated bandwidth resources to each content stream while continuously tracking total bandwidth consumption. If the cumulative allocated bandwidth remained below the total DVB-T2 bandwidth capacity, the content stream was inserted into the transmission queue. However, if the available bandwidth limit was exceeded, the algorithm evaluated whether the incoming content belonged to the emergency classification category. Emergency content triggered a dynamic bandwidth reallocation process in which lower-priority content streams were temporarily removed from the queue to free transmission resources for critical broadcasts.

Where:

• R(ci) represented bitrate allocation,

• Btotal represented total available DVB-T2 bandwidth.

Mathematical Model 11: Reallocation Criterion

Where:

• cj represented the lowest-priority removable content stream

Mathematical Model 12: Overall Algorithm Complexity

The computational complexity of the calculated scheduling framework was analyzed to evaluate algorithm scalability and operational feasibility. Sorting operations exhibited logarithmic complexity, while queue allocation operations demonstrated linear complexity. Worst-case bandwidth reallocation scenarios exhibited quadratic complexity due to repeated queue optimization processes during emergency overload conditions. Overall, the projected scheduling algorithm achieved acceptable computational efficiency for real-time DVB-T2 broadcasting applications.

This complexity level demonstrated the suitability of the algorithm for scalable real-time deployment in large DVB-T2 broadcast networks.
