What is Integrated Mobile Broadcast and How Does it Work?

Integrated Mobile Broadcast is a technology that allows mobile devices to receive broadcast signals, enabling users to access multimedia content such as videos, images, and audio without the need for internet connectivity.

This technology uses a separate broadcast network to transmit signals to mobile devices, which can then receive and decode these signals using a built-in tuner or a mobile broadcast receiver.

The broadcast network is typically a one-way communication system, where the broadcaster sends out signals to a wide area, and mobile devices can receive these signals without sending any data back.

Integrated Mobile Broadcast is a technology that allows mobile devices to receive TV, radio, and other media directly, without the need for a SIM card, Internet, or WiFi. The data stream is distributed via radio cell infrastructure, which is the same one that delivers digital terrestrial television (DTT) to our homes.

5G Broadcast, a transmission standard, is a key component of Integrated Mobile Broadcast, delivering media to mobile devices within a 60 km range of high-tower-high-power (HTHP) transmitters. It was developed by 3GPP, a collective of organizations that define protocols for mobile telecommunications.

Technical considerations are crucial for large-scale adoption of Integrated Mobile Broadcast. Device support is a key requirement, but currently only a small number of commercial devices include the necessary hardware and software to receive 5G Broadcast signals.

Device readiness is a significant challenge, as it restricts service reach to testing environments or specialized hardware. This is because DVB-I is designed to work on a wide range of devices, but 5G Broadcast support is still limited.

Network availability is another factor to consider, as 5G Broadcast requires dedicated infrastructure and spectrum allocation. This adds complexity compared to traditional mobile broadband services and may require coordination between broadcasters and telecom providers.

Service integration also presents challenges, as implementing seamless fallback from 5G Broadcast to broadband requires careful planning. Service lists, metadata, and player behavior all need to be aligned to maintain a consistent user experience.

Combining DVB-I and cellular networks offers a flexible delivery model that can serve both fixed and mobile audiences without relying on broadband infrastructure.

This combination reduces network congestion during high-demand events, making delivery more efficient.

DVB-I provides a consistent method to describe and access services across different networks, allowing service providers to show a single lineup of channels and programs.

This approach helps lower infrastructure and distribution costs for operators, as DVB-I doesn't require a dedicated app or proprietary platform, reducing development and maintenance efforts.

With DVB-I, rolling out a DVB-I/5G BC experience for consumers doesn't require a lot of effort, even with a recent and updated mobile device.

DVB-I is designed to be used on various devices, including smart TVs, phones, tablets, and other connected devices, allowing broadcasters to reach mobile audiences with reliable linear services.

As support for 5G Broadcast expands, these devices can take advantage of hybrid delivery without needing special configurations.

Mobile operators need to utilize broadcast-capable transmitters and ensure coverage areas are sufficient to support expected use cases, adding complexity compared to traditional mobile broadband services.

Dedicated infrastructure and spectrum allocation are required for 5G Broadcast, which may require coordination between broadcasters and telecom providers.

Implementing seamless fallback from 5G Broadcast to broadband requires careful planning, including aligning service lists, metadata, and player behavior to maintain a consistent user experience.

Content protection is another consideration, as broadcast delivery models require different rights management approaches than unicast streaming, and service providers need to ensure existing content agreements and licensing models are compatible with one-to-many delivery.

Real-world use cases for integrated mobile broadcast are already being put to the test, and the results are promising. Several scenarios are demonstrating the combined potential of 5G Broadcast and DVB-I.

Mobile live TV is now a reality, allowing users to access linear television services on their smartphones and tablets without installing separate apps or using mobile data. This is particularly useful for public events or in areas where broadband capacity can’t cope.

In-vehicle infotainment is another emerging use case, with DVB-I combined with 5G Broadcast allowing vehicles to receive live television or news services directly. This provides a reliable and high-quality media experience for drivers and passengers.

Public information services also benefit from this model, with emergency alerts, weather warnings, or public announcements distributed via 5G Broadcast. DVB-I ensures the information is properly categorized and made available to end users across devices.

Trials and demonstrations in countries like Germany and Italy have already explored how 5G Broadcast can be used to deliver TV services. As support grows, more broadcasters and network operators are looking into how DVB-I can provide the necessary structure and control to make those services easy to use and widely available.

5G Broadcast offers a game-changing low latency of less than one second, making it ideal for live events like Formula 1 races or Champions League games. This ensures a top-tier viewing experience for all viewers.

5G Broadcast is ready for commercial use, having been available since early 2023.

Austria was one of the first countries to test 5G Broadcast technology, with Austrian Broadcasting Services (ORS) actively involved in its development since 2019.

The first 5G Broadcast testbed was established in Vienna, Austria by 2020, with the goal of trialing the new transmission standard until the end of 2024.

The 40th Vienna Donauinselfest, Europe's largest open-air festival, was used as a test event for 5G Broadcast, with the goal of minimizing latency and hybrid distribution of live content.

Insys VT's Professional Services team set up video distribution in the backend to enable access to content from the Danube Island via both 5G Broadcast and the content delivery network of ORS.

The MotoGP event at the Red Bull Ring in Spielberg, Austria, was also used as a test event for 5G Broadcast, where various signals were transmitted directly to 5G broadcast-enabled smartphones at the race.

DVB-I makes it possible to use structured service discovery based on standardized metadata.

In a 5G environment, this means that services broadcast over a broadcast channel are as easily discoverable as services delivered over broadband or other IP-based approaches.

DVB-I converges multiple delivery modes, enabling a viewer to begin watching a service on 5G Broadcast and resume it on broadband in case of loss of coverage.

It does this through management of fallback mechanisms and provision of a unified service identity on the networks.

DVB-I handles the logic for access, discovery, and user experience, allowing broadcasters and operators to focus on content and service quality.

Not all mobile devices can receive 5G broadcast, but smartphones with a compatible chipset from suppliers like Qualcomm or Mediatek can.

A compatible chipset needs to support sub-700 MHz frequencies, particularly within the UHF spectrum of 470 to 694 MHz, and additional software like Nakolos is required to enable the app to receive 5G Broadcast from the chipset.

The first unified receiver profile for Europe was recently released to standardize technical requirements across smartphones and support wider compatibility and sustainable business models for broadcasters and network operators.

Qualcomm has already launched a prototype of the first 5G broadcast-capable smartphone at MWC 2022 in Barcelona.

Smart TVs equipped with the necessary chipsets can also support 5G Broadcast, and discussions are underway to explore its application in this area.

Using a dedicated device that receives 5G Broadcast and distributes the signal throughout your home network would be more efficient, but no such solution is currently in development.
