XCaster ATSC 1.0 and 3.0 Data Delivery System

XCaster provides a mechanism to deliver data over both ATSC 1.0 and 3.0 broadcast networks.

XCaster is particularly suitable for tranmission of educational material for remote learning applications. However XCaster can also be used to transmit firmware upgrades for a variety of devices. XCaster can also deliver standalone web sites to locations which do not have a broadband connection.

Each XCaster supports an API between itself and a designated back end to obtain data to transmit. For ATSC 1.0 transmissions, XCaster provides a Transport Stream containing the data content to be multiplexed with the channels broadcast from that site. For ATSC 3.0/NextGen TV, XCaster places the data in a NRT carousel.

XCaster also provides a fill-in mode of transmission, whereby packages are periodically re-sent, allowing new receivers and receivers that have failed to receive updates to catch up with the full set of data packages to be sent.

For ATSC 1.0 deployments, we offer S&T's XCast software. XCast will decode transports streams received by a suitable 8VSB tuner/demodulator and re-assembles the transmitted data appropriately. Data can be accessed via a WiFi connection to preserve broadband capacity (if available).

In the case of ATSC3.0/NextGenTV, data delivered in a NRT can easily be accessed by a suitable ATSC 3.0 application.
