Why in the News?

The Telecommunication Engineering Centre (TEC) has identified challenges in implementing direct-to-mobile (D2M) technology which could allow streaming TV content directly to phones without an internet connection.

What is Direct-to-Mobile (D2M) technology?

1) Direct-to-Mobile (D2M) technology refers to the capability of delivering content, such as streaming television, directly to mobile devices without the need for an internet connection.

2) The technology is based on the convergence of broadband and broadcast using which mobile phones can receive terrestrial digital TV.

3) It would be similar to how people listen to FM radio on their phones where a receiver within the phone can tap into radio frequencies.

What are the Key Challenges Identified by TEC?

1) Integration challenge– Integration of smartphones supporting D2M and Digital Terrestrial TV to Mobile Devices (DTT2M) technologies poses a major challenge.

2) Infrastructure requirements- Implementing D2M technologies like Advanced Television Systems Committee (ATSC) 3.0 also known as NextGen TV may require a new nationwide indoor network for quality services, adding complexity to the process.

3) Increased cost– Adoption of D2M technology could lead to higher cost for smartphone makers and consequently higher phone prices.

4) Ecosystem and Viability concern– Challenges include availability of a handset ecosystem, scalability of D2M technology, business viability and opportunities and spectrum requirements.

What are the Suggestions Given by TEC?

1) For D2M technology, it is essential to have a standard, compatible with current mobile handsets to ensure cost-effectiveness and capitalize on the existing ecosystem support.

2) The standard should facilitate offloading broadcasting traffic onto phones, enabling the design and manufacturing of smartphones capable of directly receiving broadcast signals.
