    摘要: According to embodiments of the invention, a system, method and computer program product for a computer program product for synchronizing content directories on cluster devices are provided. Embodiments generate a binary tree for each device in a cluster of devices, the binary tree representing the locations of all copies of content residing in the device. The binary tree for a plurality of other devices in the cluster may be stored in each device the binary tree. The binary trees for the plurality of other devices may be used to determine availability of content and the available content may be displayed to a user.

    摘要: A message pathway selection system dynamically selects an optimum message pathway for transmitting messages. The system dynamically optimizes a message pathway according to various criteria such as, for example, efficiency, economy, data requirements, auditing requirements, security, data size, etc. The system can direct a message to bypass an infrastructure messaging server, using a direct message pathway. The system can also switch from an infrastructure messaging server to a direct method. The system can also utilize an infrastructure messaging pathway either as an alternative or in parallel with the direct message pathway. The system allows an application to use a single communication system for both a direct mode and an infrastructure mode of data transfer. The present system can bypass the infrastructure message pathway, thus reducing message latency, number of messages sent, and improving overall bandwidth.

    摘要: According to embodiments of the invention, a system, method and computer program product for a computer program product for marking and acquiring sought after content are provided. Embodiments include a method comprising inserting a first desired content ID for a desired content item in a content directory for a first device in a network of media devices. The content directories of the devices in the network include content IDs of content present in the device, and also content IDs of content desired for the devices. Content directories of the other devices in the network are compared to determine if any of the other devices have a content directory containing the first desired content ID. For devices having the first desired content ID in its content directory, a determination is made of whether the desired content is present in the other device, and if the desired content is present in the other device, a copy of the desired content is transferred to the first device.

    摘要: According to one embodiment of the present invention, a system, method, and computer program product is provided for rebinding title keys in clusters of devices with distinct security levels in broadcast encryption systems. The method includes receiving a new management key and unbinding an encrypted title key with a previously used management key, the title key having a security class and residing in a title key block for a device having a security class, the device being in a cluster of devices including devices having a plurality of security classes. If the device security class is lower that the title key security class, the unbound title key is partially rebound with the new management key. the partially rebound title key is then saved in the title key block for the device.
