| 20100090403 | PRESS-YOUR-LUCK CHALLENGE - A method of hosting a press-your-luck challenge includes receiving a stake from a player and iteratively beginning phases of the press-your-luck challenge. Each phase of the press-your-luck challenge comprises dealing an active subset of game items from a set of game items. If the active subset of game items is defeated by an immediately previous subset of game items, the press-your-luck challenge is ended. If the active subset of game items is not defeated by an immediately previous subset of game items, the player is offered a return equal to a total value of the active subset of game items. If the player accepts the return, the player is awarded the return and the press-your-luck challenge ends. If the player declines the return, a subsequent phase of the press-your-luck challenge is begun. | 04-15-2010 |
| 20100120513 | GAME OF CHANCE - A game of chance includes receiving a stake corresponding to a target game-item from a player. In each phase of the game, a random integer is selected and a game-item corresponding to that integer is removed from play. If the target game-item is removed from play, the player is awarded a return and the game of chance ends. If specific game-items or combinations of game items are removed from play, the player is defeated, and the game of chance ends. A subsequent phase of the game of chance begins if the player is not defeated or awarded a return. | 05-13-2010 |
| 20100130277 | GAME OF CHANCE - A game of chance includes receiving a stake from a player. Each phase of the game of chance comprises assigning randomly selected elements to a number of game stops in the form of a pyramidal matrix. Random selection of an element for each game stop is performed independently of random selection for all other game stops. The player is awarded a return based on a composition of elements assigned to the plurality of game stops. | 05-27-2010 |

| 20080294779 | Connection Management in Peer-to-Peer Content Distribution Clouds - A topology management process is implemented which involves removing or “tearing down” connections between nodes in certain situations in order to try to replace those connections with more optimal ones. Idle connections are torn down unless those are in a “notify” state; a notify state being one in which a request for content has been made to a neighbour but that neighbour has no available content as yet. Idle connections in a notify state are torn down only if they remain idle for a longer time than that required before an idle connection is torn down. To avoid problems caused by clusters of node forming and of loners being unable to join the cloud, network churn algorithms are taught. These involve requiring nodes to drop connections when specified conditions are met. Relative content distribution between connections is monitored and this information used to influence selection of those connections to drop. | 11-27-2008 |
| 20080301246 | Peer-To-Peer Message Format Data Structure - A wire protocol is described which implements connection management and other methods to give enhanced peer-to-peer content distribution. Connections between nodes can be placed in a “notify” state when they are idle but may soon yield useful content. This notify state is also used together with a content request/response cycle to allow a peer to evaluate content available at a neighbour. If no suitable content is available a notify state is entered. When new content is later received at the neighbour it is able to inform the requesting node to allow it to restart the content request/response cycle. | 12-04-2008 |
| 20080320300 | Authorisation and Authentication - The invention relates to content distribution over a network and provides methods of controlling the distribution, of receiving the content and of publishing content. The method of controlling distribution of content over a network includes receiving a content description and location information for a source of the content from a publisher, where the content description comprises authorisation details associated with the publisher. The validity of the authorisation details is checked and if found to be valid, the content description is provided to a node in the network | 12-25-2008 |
| 20090138486 | Secure Content Descriptions - The invention describes a control node for a content distribution network and a method of automatically verifying content distributed over a network at a node in the network. In the method, a content description is received which comprises a content identifier, a publisher identifier, publisher authorisation information and content checking information. The integrity and validity of this information are checked and if both the checks are passed, the content description is stored. | 05-28-2009 |
| 20090248898 | Encoding And Decoding Optimisations - The invention provides methods of encoding content for distribution over a network and methods for decoding encoded content which has been distributed over the network. In a first example in which the content is divided into a plurality of segments and each segment comprising a plurality of blocks of data, the method comprises selecting a segment from the plurality of segments and selecting at least two blocks of the selected segment from a store of blocks. A new encoded block is created from a linear combination of the selected blocks. | 10-01-2009 |
| 20090265473 | Topology Management in Peer-to-Peer Content Distribution Clouds - A topology management process is implemented in peer-to-peer content distribution clouds using tracker nodes. Tracker nodes have information about available peers and assist peers in finding other peers to connect to. Various algorithms for use at the tracker nodes are described for selecting which peers to return as potentials for forming connections to. In addition, architectures and algorithms to allow efficient scaling of tracker nodes in peer-to-peer clouds are described. | 10-22-2009 |
