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.
