Abstract:
A system for broadcast transmission of media objects, comprising:(1) a channel management center, comprising: (a) a first scheduler, comprising: (i) a first processor; (ii) a first memory storing a first plurality of media objects, and (iii) a second memory storing first attribute data representative of broadcast attributes of the first plurality of media objects; (b) a first media-object retrieval manager having access to the stored first plurality of media objects and first broadcast-attribute data and adapted to coordinate loading of objects from the first plurality of media objects onto multiplex channels in accordance with the first broadcast-attribute data; (c) a first subscription database storing subscription information defining at least one broadcast service; and (d) means for modifying the one or more first media objects in accordance with the subscription information stored in the subscription database; and (2) a channel editing center, comprising: (a) a second scheduler, comprising: (i) a second processor; (ii) a third memory storing a second plurality of media objects, and (iii) a fourth memory storing second attribute data representative of broadcast attributes of the second plurality of media objects; (b) a second media-object retrieval manager having access to the stored second plurality of media objects and second broadcast-attribute data and adapted to coordinate loading of objects from the second plurality of media objects onto multiplex channels in accordance with the second broadcast-attribute data; (c) a second subscription database storing subscription information defining at least a second broadcast service; (d) means for modifying objects from the second plurality of media objects in accordance with the subscription information stored in the second subscription database; and (e) a multiplexer having a first input, a second input, and an output, wherein the first input of the multiplexer is adapted to receive a bitstream representative of objects from the first plurality of media objects and the second input of the multiplexer is adapted to receive a bitstream representative of objects from the second plurality of media objects, and the output of the multiplexer is transmitted to a broadcast facility.
