    Abstract: Secure handoff among devices during media playback. Playback of media, from one or more sources, on two or more respective devices is performed in an automated or simplified manner based upon a near field communications (NFC) or like security pairing transaction between those devices. The security pairing may provide direction for any of a number of operational parameters by which the media is to undergo playback on the different respective devices (e.g., source of the media, quality of the media, digital rights management (DRM), an authentication, authorization, and accounting (AAA) protocol, etc.). Certain implementations allow for user interaction to augment or override automatic or seamless operation between the respective devices for continuous playback of media thereon. Successive security pairings may be performed within any of a number of respective devices (e.g., from a first device to a second device, from a second device to a third device, etc.).

    Abstract translation: 在媒体播放期间，设备之间切换安全。 基于这些设备之间的近场通信（NFC）或类似的安全配对事务，以自动或简化的方式来执行来自一个或多个源的介质在两个或多个相应设备上的回放。 安全配对可以为多个操作参数中的任何一个提供方向，通过该操作参数媒体将在不同的相应设备上进行重放（例如，媒体的来源，媒体的质量，数字权限管理（DRM），认证， 授权和计费（AAA）协议等）。 某些实现允许用户交互来增强或覆盖各个设备之间的自动或无缝操作，以在其上连续重放媒体。 可以在多个相应设备（例如，从第一设备到第二设备，从第二设备到第三设备等）中的任一个内执行连续的安全配对。

    Abstract: A common IP layer client device interface within an IP multimedia gateway (IMG) is configured to connect client devices to broadband IP networks such as the Internet based on determined device capabilities. Broadband IP network interfaces within the IMG are configured to enable communication between the IMG and broadband IP networks based on the determined device capabilities. Content provided by various service managers are communicated with the client devices utilizing the common IP layer client device interface and the configured network interfaces. Network capabilities may be determined during the device and network discovery. Protocol translation, media transcoding and/or dynamic device configuration may be performed based on the determined device capabilities, and based on the determined network capabilities. The IMG may adjust system timing and manage power consumptions for service deployment over corresponding client devices. Information may be routed or distributed by the IMRG among the client devices when needed.

    Abstract: Different data communication architectures deliver a wide variety of content, including audio and video content, to consumers. The architectures employ channel bonding to deliver more bandwidth than any single communication channel can carry. In some implementations, the communication architectures distribute data across multiple orbital angular momentum channels in the bonded channel group.

    Abstract: A system for layered local caching of downstream shared media in a hierarchical tree network arrangement includes a first network node on a first distribution network having a first caching controller. The first network node configured to store a video segment transmitted on the first distribution network based on a first instruction received by the first caching controller from a central caching controller communicatively coupled to the first distribution network. The central caching controller is located upstream from the first network node. The system includes a second network node on a second distribution network having a second caching controller and communicatively coupled to the first network node. The second network node configured to store a video segment transmitted on the second distribution network based on a second instruction received by the second caching controller from the first caching controller.

    Abstract: A device for providing downlink channel access for non-operator devices includes at least one processor circuit. The at least one processor circuit is configured to establish a local connection with an operator device that is serviced by a network operator. The at least one processor circuit is configured to provide, to the operator device over the local connection, a request to establish a connection to a network, the request comprising a destination address. The at least one processor circuit is configured to receive, from the operator device over the local connection, control information for reception of a downlink channel provisioned by the network operator for the operator device. The at least one processor circuit is configured to receive downlink data associated with the destination address on the downlink channel and provide, to the operator device, uplink data associated with the destination address for transmission to the network.
