A method and apparatus for brokering data embedding services. The method comprises the steps of receiving a request in an embedded data brokering system to embed the auxiliary data in the media program, determining if the auxiliary data may be embedded into the media program, negotiating a schedule for broadcasting the media program with embedded auxiliary data with the media program provider, transmitting the negotiated schedule for broadcasting the media program with the embedded auxiliary data to the media program provider, steganographically embedding the auxiliary data in the media program while collecting billing information regarding the embedded data, and providing the media program and the embedded auxiliary data to the media program services subscriber for broadcast according to the broadcast schedule.

1. A method of brokering the transmission of auxiliary data in a media program from a broadcaster to at least one media program service subscriber, comprising the steps of: accepting a requested scheduling of a broadcast of the media program with steganographically embedded auxiliary data from a media provider in an embedded data brokering system, wherein the media provider has predetermined the suitability of the media program for embedding auxiliary data;scheduling the broadcast of the media program with the steganographically embedded auxiliary data;transmitting the broadcast schedule from the embedded data brokering system to the media provider;receiving the media program from the media provider in the embedded data brokering system;steganographically embedding the auxiliary data in the media program while collecting billing information regarding the steganographically embedded auxiliary data;providing the media program and the steganographically embedded auxiliary data for broadcast according to the broadcast schedule;searching a database to find further media programs in which auxiliary data may be embedded if the auxiliary data may not be embedded in the media program. 2. The method of claim 1, wherein the auxiliary data is provided to the embedded data brokering system by an auxiliary data service provider and the method further comprises the steps of: generating an invoice for embedding the auxiliary data in the media program using the collected billing information; andtransmitting the generated invoice to the auxiliary data service provider. 3. The method of claim 1, further comprising the steps of: generating an invoice for embedding the auxiliary data in the media program using the collected billing information; andtransmitting the generated invoice to the media program service subscriber. 4. The method of claim 1, wherein the billing information comprises at least one of: a character count of the auxiliary data;an identity of the auxiliary data provider;an identity of the media program data provider;a time describing when the media program and embedded auxiliary data is transmitted to the media program service subscriber;a time interval over which the media program and embedded auxiliary data is transmitted to the media program services subscriber; anda quality of service parameter for the transmission of the media program and embedded auxiliary data to the media program services subscriber. 5. The method of claim 1, wherein the auxiliary data is steganographically embedded into the media program data only according to a set of auxiliary data embedding conditions. 6. The method of claim 5, wherein the set of auxiliary data embedding conditions comprises at least one of: an indication of whether the auxiliary data is permitted to be embedded and transmitted under any circumstances;time intervals during which auxiliary data embedded into the media program data may be transmitted; andan identification of the media program data that the auxiliary data is permitted to be embedded into;an indication of whether any auxiliary data is permitted to be embedded into the media program data; andan identification of the auxiliary data that is permitted to be embedded and transmitted with the media program data. 7. The method of claim 1, wherein the media program comprises video data coded by a data compression technique, and the step of steganographically embedding the auxiliary data into the media program comprises the steps of: steganographically embedding the auxiliary data into the media program according to a key;coding the media program; andstoring the key in an unused data block of the coded media program. 8. The method of claim 1, wherein the media program comprises video data coded by a data compression technique, the coded video data describing a video frame having a plurality of pixels, and the step of steganographically embedding the auxiliary data into the media program comprises the steps of: steganographically embedding the auxiliary data into the media program according to a key; andstoring the key in at least one corner pixel of the video frame. 9. The method of claim 1, wherein the auxiliary data is related to the media program. 10. The method of claim 1, further comprising the steps of: receiving the transmitted media program with the embedded auxiliary data;extracting the embedded data; andproviding the data to a data presentation device. 11. The method of claim 10, wherein the step of extracting the embedded data comprises the steps of: reading the key; andextracting the embedded auxiliary data according to the key. 12. The method of claim 11, wherein received media program comprises data coded according to a data compression technique, and the key is read from an additional unused data block of the media program. 13. The method of claim 11, wherein the media program comprises MPEG-coded video data describing a video frame having a plurality of pixels key is read from at least one corner pixel of the video frame. 14. The method of claim 1, further comprising the step of storing the media program and embedded auxiliary data for subsequent broadcast to the media program service subscriber. 15. The method of claim 1, wherein the embedded data brokering system comprises a broadcast management system, communicatively coupled to a broadcast scheduling system and a data embedding system, wherein: the broadcast management system accepts the requested scheduling of the broadcast of the media program with steganographically embedded auxiliary data from the media provider, transmits the broadcast schedule from the embedded data brokering system to the media provider, receives the media program from the media provider, and provides the media program and the steganographically embedded auxiliary data for broadcast according to the broadcast schedule;the broadcast scheduling system generates the broadcast schedule for the broadcast of the media program with the steganographically embedded auxiliary data; andthe data embedding system steganographically embeds the auxiliary data in the media program while collecting billing information regarding the steganographically embedded auxiliary data.
