Abstract

A multimedia content dissemination system is provided for mobile vehicles. A wireless vehicle communication network provides communication among mobile vehicles in the network. At least one host vehicle within the wireless vehicle communication network is selected by an authorized entity for disseminating multimedia content received by the authorized entity. The at least one host vehicle transmits an inquiry to target vehicles in the wireless vehicle communication network. The inquiry comprises a content profile that includes descriptors associated with the multimedia content for allowing target vehicles to determine whether an interest exists in the multimedia content. The at least one host vehicle transmits the multimedia content in encrypted form to an interested target vehicle for sampling the multimedia content. The interested target vehicle requests ongoing use of the multimedia content from the authorized entity in response to sampling the multimedia content. The authorized entity provides to the interested target vehicle a decryption key for authorizing ongoing use of the multimedia content.

Claims

1. A method for cooperatively disseminating multimedia content wirelessly among mobile vehicles in a wireless vehicle communication network, the communication between mobile vehicles within the wireless vehicle communication network utilize dedicated short-range communications, the method comprising the steps of:

selecting at least one host vehicle within the wireless vehicle communication network for disseminating multimedia content;

providing multimedia content to the at least one host vehicle by an entity authorized to distribute the multimedia content;

the at least one host vehicle selectively transmitting an inquiry to target vehicles in the wireless vehicle communication network, the inquiry comprising a content profile that includes descriptors associated with the multimedia content for allowing target vehicles to determine whether an interest exists in the multimedia content;

an interested target vehicle transmitting a response to the at least one host vehicle requesting a sampling of the multimedia content;

the at least one host vehicle transmitting the multimedia content in encrypted form to the interested vehicle for sampling the multimedia content;

the interested vehicle requesting ongoing use of the multimedia content from the authorized entity in response to sampling the multimedia content; and

the authorized entity providing to the interested target vehicle a decryption key for authorizing ongoing use of the multimedia content.

2. The method of claim 1 wherein the at least one host vehicle is selected based on a mobility capability of the at least one host vehicle to contact an extensive portion of the wireless vehicle communication network.

3. The method of claim 1 wherein the at least one host vehicle is selected based on the at least one host vehicle having a specific interest in the multimedia content.

4. The method of claim 1 wherein each vehicle in the communication network includes a consumption content profile that identifies multimedia content interest based on each vehicle'"'"'s prior multimedia content usage, and wherein a respective vehicle is targeted by the at least one host vehicle based on a relevance between the multimedia content and the consumption content profile.

5. The method of claim 4 wherein consumption content profile is transmitted between vehicles as part of a beacon message.

6. The method of claim 4 wherein a respective target vehicle receiving the inquiry compares its consumption content profile to the content profile of the multimedia content for determining whether an interest exists in the multimedia content.

7. The method of claim 6 wherein consumption content profile of the respective target vehicle matches each of the descriptors of the content profile of the multimedia content for establishing an interest.

8. The method of claim 6 wherein consumption content profile of the respective target vehicle matches a predetermined number of the descriptors of the content profile of the multimedia content for establishing an interest.

9. The method of claim 1 wherein the multimedia content provided to the interested vehicle for a sample playback is logged with the authorized entity.

10. The method of claim 1 wherein the interested vehicle requesting the ongoing usage of the multimedia content purchases the multimedia content from the authorized entity.

11. The method of claim 1 wherein the at least one vehicle disseminating the multimedia content to the interested target vehicle receives compensation by the authoritative entity for the purchase by the interested target vehicle.

12. The method of claim 1 wherein a temporary decryption key is obtained from authoritative entity for sampling the multimedia content.

13. The method of claim 12 wherein the temporary decryption key provides access to the multimedia content for a one-time sampling.

14. A multimedia content dissemination system for mobile vehicles, the system comprising:

a wireless vehicle communication network providing communication among the mobile vehicles of the network, the wireless vehicle communication network utilizing dedicated short term communications between the mobile vehicles;

an authorized entity for initiating distribution of multimedia content;

at least one host vehicle within the wireless vehicle communication network selected by the authorized entity for disseminating multimedia content received by the authorized entity, the at least one host vehicle transmitting an inquiry to target vehicles in the wireless vehicle communication network, the inquiry comprising a content profile that includes descriptors associated with the multimedia content for allowing target vehicles to determine whether an interest exists in the multimedia content;

wherein the at least one host vehicle transmits the multimedia content in encrypted form to an interested target vehicle for sampling the multimedia content, wherein the interested target vehicle requests ongoing use of the multimedia content from the authorized entity in response to sampling the multimedia content, and wherein the authorized entity provides to the interested target vehicle a decryption key for authorizing ongoing use of the multimedia content.

15. The multimedia content dissemination system of claim 14 further comprising a tracking module for logging the dissemination of the multimedia content from the at least one host vehicles to the target vehicles.

16. The multimedia content dissemination system of claim 15 wherein the tracking module includes a log for tracking purchases of the multimedia content by the target vehicle.

17. The multimedia content dissemination system of claim 14 further comprising a temporary decryption key, wherein the temporary decryption key is provided from the authoritative entity to the target vehicle for sampling the encrypted multimedia content.

18. The multimedia content dissemination system of claim 14 further comprising a target-seeding module for selecting the at least one host vehicle.

19. The multimedia content dissemination system of claim 18 wherein the target-seeding module is a mobility-seeding module, and wherein the at least one host vehicle is selected based on a mobility capability to contact an extensive portion of the wireless vehicle communication network.

20. The multimedia content dissemination system of claim 18 wherein the target-seeding module is an interest-seeding module, and wherein the at least one host vehicle is selected based on a vehicle having a specific interest relating to the multimedia content.
