Title:
METHOD FOR PROVIDING INCENTIVE MECHANISMS FOR OUT-OF-ORDER DOWNLOAD IN COMMUNICATION NETWORKS DEDICATED TO THE DISTRIBUTION OF VIDEO-ON-DEMAND CONTENT
Document Type and Number:
WIPO Patent Application WO/2010/094561
Kind Code:
A3
Abstract:
The present invention concerns a method of transferring content from a first communication device (D1 ) to a second communication device (D2) in a communication network, comprising the following steps: • defining a first probability (pe), according to which a content can be encoded; • defining a second probability (pc), according to which a content can be chosen; • upon request of content (x) from said second communication device (D2) to said first communication device (D1 ): • encoding content (x) with another content (y) according to said first probability (pe), said content (y) being chosen with said second probability (pc), and transferring content z = x XOR y from said first communication device (D1 ) to said second communication device (D2), or • according to probability 1 -pe transferring unencoded content x from said first communication device (D1 ) to said second communication device (D2).
