Direct-to-Mobile (D2M) Broadcasting: Revolutionizing Content Delivery and Governance
GS3GS2
The Department of Telecommunications is piloting D2M technology to stream video content directly to mobile devices without an active internet connection. This innovation aims to bridge the digital divide, ease cellular network congestion, and enhance public service delivery.
The Department of Telecommunications (DoT) has announced pilot projects for Direct-to-Mobile (D2M) broadcasting technology in major Indian cities. D2M is a hybrid technology that allows mobile devices to receive multimedia content, such as live TV and videos, directly through broadcast signals, similar to how a radio or television functions, bypassing the need for a cellular data connection.
Technologically, D2M works by converging broadband and broadcast. It utilizes the terrestrial broadcast infrastructure—traditionally used for TV signals—to transmit content to mobile phones equipped with compatible hardware. This shift is significant because nearly 80% of internet traffic in India is currently video-driven, which often leads to network congestion on 4G and 5G bands. By offloading video traffic to broadcast frequencies, D2M can significantly improve the Quality of Service (QoS) for other data-intensive applications.
