Abstract
Systems and methods are disclosed describing the transmission of multimedia data to a mobile device. A system describing some of the disclosed embodiments comprises a mobile digital television transmitter transmitting a primary data stream, a transceiver transmitting a secondary data stream, and a mobile device. In some embodiments the mobile device comprises a mobile display, a mobile transceiver, and a mobile processor and receives at least the primary data stream and the secondary data. The mobile device displays data from either the primary data stream or the secondary data stream, and transmits a mobile data stream to the transceiver. The mobile data stream may comprise information relating to the status of both the primary data stream and the secondary data stream. This system may also include a server in communication with the transceiver, wherein the server is capable of determining the signal conditions of the mobile device based upon the mobile data stream and alter the secondary data stream based upon the mobile data stream.
