摘要： A system and method of serverless peer-to-peer group management and maintenance is presented. Group formation and discovery of private, public, and enumerated groups are provided, as is a method of joining such a peer-to-peer group. Group information management provided by the present invention ensures that each node maintains a current database from the initial joining of the group through the run phase of membership. Group graph maintenance utilizes a group signature to ensure that partitions in a graph may be detected and repaired. The utility of connections within the graph are also monitored so that non-productive connections may be dropped to increase the efficiency of the group. The diameter of the graph is also monitored and adjusted to ensure rapid information transfer throughout the group. A disconnect procedure is used to maintain the graph integrity and prevent partitions resulting from the departure of a group member.

摘要： A method for ensuring valid and secure peer-to-peer communications in a group structure. Specifically, the system of the present invention presents a method of ensuring secure peer-to-peer group formation, group member addition, group member eviction, group information distribution, etc. Such functionality may be distributed to the individual peers in the group to further enhance the overall security of the group while enhancing flexibility. The P2P group security allows every peer who is a valid member of the group to invite new members. The recipients of these invitations are then able to contact any member of the group to join the group, not only the inviter. Further, groups may function when the group creator is not online. Likewise, the method allows the creation of secure groups with users from different security domains, relying on their security credentials in those domains for initial authentication.

摘要： A method for use in a peer-to-peer communication system to ensure valid connections are made in a secure manner includes the steps of receiving an address record for a peer node which includes an ID certificate. The ID certificate is validated and checked to verify that the ID certificate has not expired. Further, the method determines if the node from whom the address record was received is to be trusted, and the number of instances of the IP address included in the certificate is already stored in cache. When the foregoing are completed successfully, i.e. the certificate is valid, not expired, has been supplied by a trusted neighbor, and does not point to an IP address that already exists for different ID's multiple times, the method opportunistically verifies ownership of the ID certificate at the peer node's IP address. That is, the verification of ownership only occurs when the advertiser of the ID is the owner of that ID (or when the ID is to be used). If any of the above cannot be completed successfully, the address record is discarded.

摘要： A shared concept of time, called “graph time,” is agreed upon by all nodes within a graph. Each node maintains its own local delta representative of a difference in the node's system clock and graph time. Upon connecting to a neighbor node in a graph, a node is sent graph time as perceived by the neighbor node. In accordance with an embodiment, the node assumes that the lag time in receiving the graph time from the neighbor node is one-half of the lag time between the request for the connection and the receipt of the graph time. Graph time as sent by the neighbor node is added to one-half of the total delay and the sum is subtracted from the node's system time to calculate the delta for the node requesting connection.

摘要： A multiuser scheme allowing for a number of users, sets of user, or carriers to share one or more channels is provided. In the invention, the available channel bandwidth is subdivided into a number of equal-bandwidth subchannels according to standard OFDM practice. A transmitter transmits data on a set of OFDM subchannels that need not be contiguous in the spectrum or belong to the same OFDM channel. A receiver receives and decodes the data and detects errors on subchannels. The receiver then broadcasts the identity of those subchannels on which the error rate exceeds a specific threshold, and the transmitter may select different subchannels for transmission based on this information.

摘要： The subject disclosure is directed towards a hybrid stereo image/motion parallax system that uses stereo 3D vision technology for presenting different images to each eye of a viewer, in combination with motion parallax technology to adjust each image for the positions of a viewer's eyes. In this way, the viewer receives both stereo cues and parallax cues as the viewer moves while viewing a 3D scene, which tends to result in greater visual comfort/less fatigue to the viewer. Also described is the use of goggles for tracking viewer position, including training a computer vision algorithm to recognize goggles instead of only heads/eyes.
摘要翻译：本发明涉及一种混合立体声图像/运动视差系统，其采用立体3D视觉技术，用于向观看者的每只眼睛呈现不同的图像，并结合运动视差技术来调整每个图像以供观众眼睛的位置。以这种方式，当观看者在观看3D场景时移动时，观众接收立体声提示和视差提示，这倾向于导致更大的视觉舒适度/对观看者的疲劳。还描述了使用护目镜跟踪观察者位置，包括训练计算机视觉算法来识别护目镜而不仅仅是头/眼。
