Abstract: The subject system allows electronic devices in an infrastructure network to discover direct peer-to-peer services, such as screencasting, access to peripheral devices, etc., that can be provided over the infrastructure network. Since the electronic devices already have a layer two (link layer) connection with each other over the infrastructure network, pre-association device and/or service discovery protocols, such as those provided by Wi-Fi Direct and the like, are not available to the electronic devices. Thus, the subject system provides a post-association mechanism that allows the electronic devices to query, advertise, discover, and access direct peer-to-peer services over the infrastructure network. Furthermore, the subject system extends access of the direct peer-to-peer services to wired networks, such as Ethernet networks, Multimedia over Coax Alliance (MoCA) networks, powerline networks, and the like.

Abstract: The subject system allows a source device providing a content stream over a network connection to a sink device to adaptively bypass a transcoding portion of a content processing pipeline when the original content stream, e.g. the non-transcoded content stream, can be decoded by the sink device and/or when no actions that utilize transcoding have been requested for the content stream. The source device may power down the transcoding portion of the content processing pipeline when the transcoding portion is not in use. When an action that utilizes transcoding is requested, and the transcoding portion of the pipeline is being bypassed, the source device may power on the transcoding portion and adaptively modify the pipeline to pass the content stream through the transcoding portion. The source device may provide configuration messages to the sink device when the pipeline is modified to provide information for decoding the transcoded content stream.
