    摘要： A broadband gateway, which that enables communication with a plurality of devices, handles at least one physical layer connection to at least one corresponding network access service provider. The broadband gateway may identify video layer information required for a layered video service based on video decoding capabilities and/or power profiles for the devices. The identified video layer information, comprising number of required layers and corresponding video formats such as 720P60, 1080i60 and/or 1080P60, may be communicated to the at least one network access service provider. A base layer video and one or more enhancement layer videos, generated via scalable coding based on the communicated identified video layer information, may be received from the at least one corresponding network access service provider. The received base layer video and enhancement layer videos are selectively provided to the devices for the requested layered video service based on the corresponding video decoding capabilities and/or power profiles.

    摘要： Methods and systems for estimating an angle of arrival are provided. In an embodiment, a system for estimating angle of arrival includes a snapshot determining module configured to receive a signal from each antenna of an antenna array and to generate a snapshot vector including values based on the signals and an angle of arrival processing module configured to estimate an angle of arrival for the electromagnetic signal relative to the antenna array based on the snapshot vector. Each signal is representative of an electromagnetic signal incident on a respective antenna of the antenna array and each value is representative of a phase of a respective signal.

    摘要： A broadband gateway, which enables communication with a plurality of devices, handles at least one physical layer connection to at least one corresponding network access service provider. Before allowing the devices to access content from the service provider, the broadband gateway may identify a device power profile for each of the devices, and a network power profile for the content to select a corresponding content delivery mechanism to optimize power consumption. The content may be communicated to the devices utilizing the corresponding selected content delivery mechanism. Depending on configuration, content transcoding may be performed at the broadband gateway and/or at the devices. The content may be burst downloaded and stored in a local storage to be consumed by the devices thereafter. Upon completion of download, the broadband gateway may shut down receiving components to save resources and power. The receiving components may be tuned on to receive additional content when needed.
