METHOD AND SYSTEM FOR DISTRIBUTING DATA |
摘要 |
A method and system for distributing data to at least one communication device are disclosed. When multiple communication devices request the same data, a seeder sends a different piece of the data to each communication device and the communication devices share the piece of data each other by using a wireless connection established between them. The communication devices automatically suspend and resume downloading of the piece of the data from other communication devices as the communication device performs a handover. The receiver may be given super-distribution rights. When a destination communication device requests data, a content provider identifies a source communication device which possesses the same data and has the source communication device to forward the data to the destination communication device. The source communication device re-encrypts the data with a new encryption key and the destination communication device obtains a license from a rights issuer to decrypt the data.
