Digital Radio and Direct-to-Mobile Technologies Transform Mass Communication; Enable Affordable Entertainment and Education, and Robust Critical Messaging

**Executive Summary** The Ministry of Information and Broadcasting is promoting Digital Radio and Direct-to-Mobile (D2M) technologies to optimize spectrum use for affordable entertainment, education, and emergency alerts. Additionally, the Telecom Regulatory Authority of India (TRAI) has implemented a blockchain-based Distributed Ledger Technology (DLT) platform to curb spam calls and manage consumer preferences. These initiatives are supported by the BIND scheme for the modernization of Prasar Bharati’s infrastructure. **Key Points / Main Content** * **Emerging Broadcasting Technologies** * Digital radio creates an affordable, free-to-air ecosystem by delivering multiple channels over a single frequency. * Direct-to-Mobile (D2M) technology broadcasts video, audio, and data directly to mobile handsets using terrestrial infrastructure. * D2M operates independently of SIM cards or mobile data, providing a robust "data pipe" for mass communication and disaster management alerts. * **Regulation of Unsolicited Commercial Communication (UCC)** * TRAI regulates spam calls under the Telecom Commercial Communications Customer Preference Regulations (TCCCPR). * A Distributed Ledger Technology (DLT) platform (blockchain) allows consumers to register their preferences regarding promotional communications. * The DLT platform includes a complaint mechanism for reporting issues with both registered and unregistered telemarketers. * **Infrastructure and Policy Support** * The Broadcasting Infrastructure and Network Development (BIND) scheme is a Central Sector Scheme focused on the development and modernization of Doordarshan and Akashvani. * Prasar Bharati is tasked with the continuous digitalization and upgradation of its networks to incorporate latest equipment and emerging technologies. **Impact Analysis** **Consumers** **Impact** Consumers gain access to affordable, free-to-air digital content and a more robust system for emergency alerts. They also benefit from reduced spam calls and a transparent mechanism for managing communication preferences. **Action Required** Register preferences regarding promotional communications and lodge complaints against telemarketers via the DLT platform when necessary. **Principal Entities (Banks, Insurance Companies, Airlines, etc.) and Telemarketers** **Impact** These entities are subject to stricter regulation of promotional activities and must operate within the blockchain-based DLT framework. **Action Required** Register on the DLT platform and adhere to TCCCPR regulations when sending promotional communications. **Prasar Bharati (Doordarshan and Akashvani)** **Impact** The organization is the primary beneficiary of the BIND scheme, receiving support for modernization and the adoption of emerging broadcasting technologies. **Action Required** Continuously upgrade networks, digitalize infrastructure, and implement latest equipment as per the Ministry's policy directions.
