Datacasting with ATSC 3.0

Datacasting is the process of broadcasting data over a wide area using television or radio signals, typically to deliver internet content without the need for a broadband connection.

Datacasting works by embedding digital data into traditional broadcast signals, which can then be received and decoded by compatible devices. At Trilogy Next Gen, we're harnessing the power of datacasting to revolutionize how digital data is transmitted.

Until recently, datacasting was limited to radio or tv signals, meaning only audio or video content could be datacast. That’s because the underlying standards-based technology relied on ATSC 1.0. In 2017, the industry approved ATSC 3.0 for use, enabling any type of content (image files, text files, audio and video files, etc.) to be easily transmitted, point to multipoint. 

Using ATSC 1.0, datacasting was used to deliver public safety data to police, fire, and other first responders. Now, thanks to ATSC 3.0, the capabilities of datacasting have greatly expanded. It can now be used to provide real-time traffic updates and alternative driving routes to improve transportation in smart cities and broadcast public meeting schedules and information about local services and events. It’s also ideal for alerting area citizens to hyper-local weather and other safety threats, providing residents with real-time energy consumption data from the local utility and enabling business to target their advertising like never before.

Datacasting benefits schools and universities by providing a cost-effective way to distribute educational content to multiple locations simultaneously, especially where internet access is limited. It enables reliable delivery of lessons, multimedia resources, and critical updates to students and faculty, ensuring equal learning opportunities for remote or underserved areas.

The ATSC is an international non-profit organization that develops voluntary standards for digital television, including datacasting, used primarily in North America.

The version of the Advanced Television Systems Committee (ATSC) standards used for datacasting is primarily ATSC 3.0. This latest version, also known as NextGen TV, has been designed to support enhanced data transmission capabilities alongside traditional audio and video content. ATSC 3.0 utilizes advanced encoding and modulation techniques, allowing for more efficient use of broadcast spectrum.

ATSC 3.0 is the latest version of the ATSC standards, offering significant enhancements over previous versions. These improvements include:

• Improved Picture and Sound Quality: Supports 4K Ultra HD resolution and immersive audio formats.
• Interactivity and Personalization: Offers interactive features and personalized content, enhancing viewer engagement.
• Better Signal Reception: More robust signal that improves reception, especially for mobile devices and TVs without outdoor antennas.
• Hybrid Broadcast-Broadband Capabilities: Allows integration of broadcast and internet content.
• Advanced Emergency Alerts: Enhanced alert systems provide more detailed and localized emergency information.
