Abstract
A data broadcasting system is disclosed. The data broadcasting system operates by receiving source material from a number of different sources. The source material is processed by performing adding error correction encoding and in some cases, encryption. The source material from the different sources is then multiplexed together and broadcast on a broadcast medium. The multiplexed digital broadcast is received by a plurality of receiver systems. The receiver systems demultiplex the multiplexed digital stream to obtain desired digital streams. The desired streams are then decrypted if necessary.
