    摘要： One or more methods and systems of indexing an AVC video stream are presented. In one embodiment, the method comprises identifying one or more fields within a picture of an AVC video stream. In one embodiment, a field of the one or more fields indicates the beginning of each picture. In a second embodiment, a field of the one or more fields indicates a picture type of a picture. In a third embodiment, a field of the one or more fields indicates whether a picture is a reference or a non-reference picture. By determining that a picture is a non-reference picture, the picture may be discarded, thereby reducing the memory required to implement the indexing system while increasing the available memory size. In one embodiment, a system of indexing an AVC video stream comprises a control processor, a memory, and a set of instructions resident in the memory.

    摘要： A social network (SNET) is divided into one or more circles employing separate security secrets, e.g. keys, for communication between members. A device can be a member of more than one circle, and store different keys for each of those circles in separate, restricted portions of memory. When a member leaves a circle, new keys can be generated and distributed to the remaining members. Before and after joining a circle, a level of trust associated with the device or human member can be determined based on third party trust verification and a trust history. A requirement for multiple current circle members to vouch for the prospective member can be imposed as a condition of membership. Each circle can be assigned different trust and access levels, and authorization to receive information can be checked before transmitting information between circles.

    摘要： A Set Top Box (STB) or client computer includes a communication interface operable to receive digital messages and digital content, memory operable, and processing circuitry coupled to the communication interface and to the memory. The STB is operable to receive a digital message, extract a key portion from the digital message, extract a rights portion from the digital message, determine a code version based upon the rights portion, read a stored code version from the memory, and compare the code version to the stored code version to validate the software instructions. Upon an unfavorable comparison of the code version to the stored code version, initiates an error action that may include sending a message to a service provider device for software instruction reloading, rebooting, and/or disable decryption of the digital content. Extracting the rights portion from the digital message may include decrypting the key portion to produce a decrypted result and decrypting the rights portion using the decrypted result to produce the decrypted rights portion.

    摘要： Transmitting streamed video to at least one wireless terminal by a wireless network having a channel frequency reuse pattern. The wireless network receives a request for the streamed video from the at least one wireless terminal and receives position information from the at least one wireless terminal requesting the streamed video. The wireless network selects a transceiving device to service transmission of the streamed video to the at least one wireless terminal. The transceiving device is allocated a first channel frequency set of the channel frequency reuse pattern. The wireless network or a component thereof selects a channel from a second channel frequency set that is different from the first channel frequency set. The transceiving device then, using a directional antenna, transmits the streamed video to the at least one wireless terminal in a direction based upon the position information using the selected channel.

    摘要： A social networking system enables sharing of content between various members, devices, infrastructures, and the like based upon membership in a social network (SNET group). Content can be protected by limiting access to the content to members of an SNET group, members associated with various devices docked to the SNET group, and the like. Joint access of content by various members of an SNET group can be managed to ensure synchronized access of content and interactions between SNET accessing group members. Instances of a content item can be distributed to multiple destination devices associated with an SNET group, where various instances are transcoded to accommodate varying capabilities and characteristics of various communication pathways and the destination devices and ensure synchronized access of the content item by the multiple destination devices. Interactions between members of an SNET group can be managed to leverage links to other SNET groups.
