摘要： A logical tree structure and method for managing membership in a multicast group provides scalability and security from internal attacks. The structure defines key groups and subgroups, with each subgroup having a subgroup manager. Dual encryption allows the sender of the multicast data to manage distribution of a first set of encryption keys whereas the individual subgroup managers manage the distribution of a second set of encryption keys. The two key sets allow the sender to delegate much of the group management responsibilities without compromising security because a key from each set is required to access the multicast data. Security is further maintained via a method in which subgroup managers can be either member subgroup managers or participant subgroup managers. Access to both keys is provided to member subgroup managers whereas access to only one key is provided to participant subgroup managers. Nodes can be added without the need to generate a new encryption key at the top level which provides improved scalability.
摘要翻译：用于管理多播组中的成员资格的逻辑树结构和方法提供来自内部攻击的可扩展性和安全性。该结构定义了关键组和子组，每个子组都有一个子组管理器。双重加密允许多播数据的发送者管理第一组加密密钥的分发，而各个子组管理器管理第二组加密密钥的分发。两个密钥集允许发送方委托大量的组管理职责，而不会影响安全性，因为需要每组密钥来访问组播数据。通过子组管理员可以是成员子组管理员或参与者子组管理器的方法进一步维护安全性。向成员子组管理员提供对这两个密钥的访问，而只向一个密钥的访问提供给参与者子组管理器。可以添加节点，而无需在顶层生成新的加密密钥，从而提供改进的可扩展性。

摘要： A network comprises agents which act as proxies on behalf of devices, such as wireless game devices, phones and personal digital assistants. Each agent collects information concerning a “presence status” of a device. An agent determines whether to forward messages on to a device depending on the collected presence status (e.g., active/inactive) of the device. For example, if the presence status indicates the device is active then messages will be forwarded. If, however, the status indicates the device is inactive the message will not be forwarded. Instead, the agent may act as a proxy for the device while it is inactive. By only forwarding messages when a device is active, valuable airlink time and/or bandwidth can be conserved.
摘要翻译：网络包括代表设备（如无线游戏设备，电话和个人数字助理）的代理。每个代理收集有关设备“存在状态”的信息。代理根据收集的设备的状态（例如，主动/不活动）来确定是否将消息转发到设备。例如，如果存在状态指示设备处于活动状态，则消息将被转发。但是，如果状态表示设备处于非活动状态，则不会转发该消息。相反，代理可以在设备处于非活动状态时作为设备的代理。只有当设备处于活动状态时才转发消息，可以节省有价值的空中链路时间和/或带宽。

摘要： The invention includes a method and apparatus for synchronizing an asset within application space. The method includes receiving asset information comprising an original position of the asset within application space on a sending system and a trajectory of the asset within application space on the sending system, and determining an updated position adapted for placing the asset within application space on a receiving system, wherein the updated position is determined using the original position, the trajectory, and an expected propagation delay from the sending system to the receiving system. The expected propagation delay between the sending and receiving systems is determined by one or more network proxies. The original position and trajectory of the asset may be received in a data structure which may be modified to include the updated position for use by the receiving system in placing the asset within application space on the receiving system.

摘要： A transport system allows delivery of MPEG video streams from a network server to a media client while avoiding network delays associated with transition between files contained in these streams. A buffering system, a transport controller, and a counter allow buffering and interim delivery of MPEG stream data. The transport controller can either deliver MPEG stream data directly to the media client, or route data through the buffering system. The buffering system includes a population buffer for storage of interim MPEG stream data, and a transport buffer for temporary storage of MPEG stream data during continuous delivery. During transitional delivery, the transport controller delivers interim data to the media client until the requested file is available and uses the counter to select the proper start location in the requested file.

摘要： The distributed multimedia server employs modular server elements that connect with client systems through a high bandwidth network. The server elements are connected in interleaved fashion with the switching elements and the data representing different media selections are arranged in stripe groups distributed across the server elements. The server can be as small as a single server element or grown incrementally, as needed, by connecting additional server elements to the system. Multiple copies of hot media selections are stored across the distributed architecture within different stripe groups to minimize bottlenecks within the storage subsystem.

摘要： Embodiments of the present invention are methods for selecting, out of a lineup of IPTV channels, a subset of channels for caching. The methods take into account viewers' tendency to walk through the channels that lie between their current channel and their desired channel if that walking distance is short, and, alternatively, viewers' tendency to jump to a distant channel. Accordingly, embodiments of the present invention include any channel selection method which selects for caching any number of channels less than the entire lineup, and where at least two of those channels form a segment of adjacent channels. Other embodiments include methods which rely upon specific extrinsic data, e.g., IGMP and EPG information, for selecting a subset of channels to be cached.
摘要翻译：本发明的实施例是用于从IPTV频道的阵容中选择用于高速缓存的信道子集的方法。这些方法考虑到观众倾向于通过位于其当前频道和所需频道之间的频道，如果步行距离短，或者观众倾向于跳到遥远的频道。因此，本发明的实施例包括任何频道选择方法，其选择用于缓存小于整个阵容的任何数量的信道，并且其中这些信道中的至少两个形成相邻信道的分段。其他实施例包括依赖于特定外在数据（例如IGMP和EPG信息）的方法，用于选择要缓存的信道的子集。
