Students with devices at home

What is Datacasting? Datacasting is a term derived from ‘data’ and ‘broadcasting’.

The technology converts a portion of the broadcast signal to offer a one-way transmission of encrypted IP data. Datacasting offers the same coverage as terrestrial signals and utilizes an existing network infrastructure.

About the Pilot

Several agencies have used datacasting to support public safety and public emergency incidents. Although the concept of datacasting has been around for many years, the idea of using the technology for education is a new one. South Carolina ETV is pioneering a pilot project, in collaboration with Spectrarep, to explore how datacasting can help to address the digital divide by providing instructional content to students without Internet access.

What is the End-User Experience?

In order to receive files via datacasting, a student will need a Wi-Fi enabled device (i.e., cell phone, computer, tablet, etc.), as well as an inexpensive antenna and receiver. No internet access is required.

Any type of file (jpg, PDF, mp4, etc.) can be transmitted via datacasting. This means that the possibilities of creating and packaging content designed for instruction are limitless.

Our goal is to create a personalized learning experience for students that would not otherwise have access to a multitude of online resources. The pilot will explore the amount of time it takes for files to be transmitted over the encrypted signal to a student laptop. Additionally, the pilot will determine what students will see when they receive the files on their laptop, best practices for end-user equipment and instructional content creation. Discussions are also ongoing about models for returning completed work/assignments to a teacher.

SCETV is using brand familiarity to implement the datacasting pilot – is a home-grown site that includes nearly 9,000 media assets to include videos, lessons, documents, and interactives. The content from and PBS Learning Media, will be used to compile instructional units that will be datacast to students. End users will receive a HTML page that outlines what they “must do” versus what they “can do.” There is an opportunity to add content from other sources (e.g., recorded lectures, other online websites) and to customize content for end users based on a number of different variables.

What are the Costs Associated with the Pilot?

Costs will vary depending on the scope of the project. As a state/agency, there are one-time costs associated with the infrastructure required to support datacasting (software client, encoders, bandwidth, etc.). Within South Carolina, SCETV is working with the appropriate entities to cover these costs. For individual districts within the state, costs can include the purchase of student devices (if desired), antenna, and receiver for each end user. Other costs may include personnel resources to support the packaging of content and the provision of technical support to end users.

When Will Datacasting Become Available for Educational Use?

SCETV is currently deploying a phased pilot approach for select South Carolina schools/districts that will take place over the next 12 months. Initial pilot districts include Fairfield, Jasper, and York One. Conversations are ongoing with other partners across the state. The ability to make datacasting available to end users in a targeted area will vary depending key readiness factors (i.e., educational content, technology, funding). Priority will be given to those districts that have been disproportionately impacted by the Coronavirus pandemic.  

How Can My Organization Become Involved?

Interested organizations within South Carolina should reach out to SCETV at Those outside of South Carolina should reach out to the representatives at Spectrarep and they will help you get started.
