System and method for transmitting digital multimedia data with analog broadcast data
First Claim
1. A method of transmitting digital data on at least one RF carrier of an audio broadcast, comprising:
- identifying digital data associated with, but different than a set of broadcast data;
determining synchronization data corresponding to a broadcast event within the set of broadcast data;
assembling a data packet including the digital data and the synchronization data; and
transmitting the data packet to a receiver before the broadcast event, such that the broadcast data is presented with the digital data based on the synchronization data to a consumer of the broadcast data.

Abstract
A method and system for the transmission of digital data (210) over existing analog radio frequencies (230) is presented, wherein the digital data may include audio data, visual data or audio-visual data for presentation either with analog broadcast data or at a selectable time. The digital data may be transmitted over a plurality of sub-channels that have varying degrees or reliability (250). A “quality-of-service” process manages the transmission of digital data over various sub-channels based on the reliability of the sub-channel, the amount of digital data and the type of digital data to be transmitted. The digital data may further be encrypted and authenticated.

18. A computer comprising:
-
a user interface; and a control system operatively coupled to the user interface and adapted to; identify a set of broadcast data that will be sent to a consumer through an RF channel as part of a one-way audio broadcast; identify digital data associated with, but different than the set of broadcast data; determine synchronization data corresponding to a broadcast event within the set of broadcast data; assemble a data packet comprising; the digital data; and the synchronization data; and transmit the data packet to a receiver before the broadcast event using an in-band, on-channel format, such that the set of broadcast data is presented with the digital data based on the synchronization data to the consumer of the broadcast data.
