DHS Releases Information on Video Datacasting Project for Public Safety

The Department of Homeland Security (DHS) Science and Technology Directorate’s (S&T) First Responders Group (FRG) released a 100-second video on its video datacasting project.

Datacasting is a way to transmit encrypted live video and data over existing broadcast TV signals outbound to a targeted audience that can download it in the field. When broadcast television transitioned from analog to digital broadcast transmissions, it created the opportunity to use TV spectrum in new ways, including delivering one-to-many encrypted and targetable video and computer data outbound to recipients.

With the right design and setup, broadband devices to be used by first responders for the First Responder Network Authority (FirstNet) nationwide public-safety broadband network should also be able to receive content downloaded through video datacasting.

The project takes advantage of a portion of the public broadcasting station’s bandwidth normally used for television programming. The video explains how DHS partners Johns Hopkins University Applied Physics Lab, SpectraRep and several Public Broadcasting Service (PBS) television stations are working together to enhance public-safety communications and provide speedy transmission of video and data.

Following two pilots conducted earlier this year, after action reports are being produced and will be released with information on the capabilities and potential limitations of the technology for public-safety use. S&T is also looking to identify other potential public-safety partners and pilot locations for fiscal year 2016 to test additional capabilities.

More information and the video are available on the DHS website.
