3pi is a Linux based, low-cost and low power ATSC 3.0 datacast receiver based on the popular $35 Raspberry Pi platform.3pi targets NEXTGENTV datacasting applications. 3pi is based on our proven ATSC3pak software that has already been deployed by broadcasters in set-top boxes. 3pi also uses the same proven software we are already shipping in our set-top box platform called ATSC3pro.

The 3pi platform can be cost reduced to an ultra low-cost device. It can also be deployed as-is. Broadcast transmission costs can reach as low as $0.001/GB.
