Abstract
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.
