TRACKER IN P2 P SYSTEMS WITH DVD FUNCTIONALITIES
First Claim
Patent Images
1. A method of grouping peers in a P2P system where DVD jump operations can be performed, the method comprising the steps of:
- a. determining for each peer and video operation a time T and a jump point Pj b. generating a hash key Hj for each peer, the hash key having a value Hj=(Pj−
T)/C, where C>
=1 is a granularity of the systemc. grouping peers with the same hash-key.

Abstract
“A method of optimizing the design of a Tracker in P2P applications to support DVD features, the method including determining for each peer and video operation the time T and jump point Pj, generating a hash key HKj for each peer, the hash key having a value Kj=(Pj−T)/C, where C>=1 is the granularity of the system, and grouping the peers with the same hash, where the system is designed to provide good viewer experience while supporting DVD features like pause, forward and backward jump operations.”
