  • Patent number: 8928812
    Abstract: A system for controlling ambient light effects comprises a receiving device including at least one processor programmed to parse incoming video content to detect at least one portion of the incoming video content and determine at least one ambient light effect to be associated with the portion of the video content. The system further comprises a home automation controller in communication with the processor and at least one lighting device in communication with the receiving device and the home automation controller. The processor of the receiving device is programmed to send a command to the home automation controller specifying the ambient light effect determined by the processor to be associated with the portion of the video content. The lighting device generates the ambient light effect specified in the command when the portion of the video content is displayed to a user.

  • Publication number: 20150007288
    Abstract: An apparatus and method for a multi-tier wireless home mesh network is described. The method may include formation of an infrastructure-less wireless home mesh networking environment comprising a collection of nodes that operate as a decentralized, ad hoc wireless network with multiple sub-networks or tiers that, are responsible for different functions within the network. Each node of the multi-tier network is configured to forward data to other nodes and is assigned to a particular tier based on the node's performance capabilities. A further embodiment includes identification of a wireless home mesh network. Once identified, one or more proprietary messages may be exchanged in a secure manner to establish connections with a home electronics device as either a mobile node or a stationary node of the home network. A home electronics device may wirelessly communicate to route data within one or more nodes of the wireless home mesh network. Other embodiments are described and claimed.

  • Patent number: 8908631
    Abstract: An embodiment is a technique to perform network-based traffic recognition and packet classification. A port identifier in a transport layer header of a packet having a packet type associated with a priority level is extracted. The packet is transmitted from or to an application according to a network protocol in a multi-hop mesh network having a local node and a remote node. The port identifier includes a port number. The packet is classified into the packet type using the port identifier and one of a pre-defined port list, a dynamic port table, and an application header of the application.

  • Patent number: 8904177
    Abstract: A method for a multi-tier wireless home mesh network may include authentication of a node within a wireless home networking environment after discovering a wireless home mesh network. The authentication comprises (1) transmitting a first message, the first message including (i) an encrypted pass-phrase being a pass-phrase encrypted with a public key of the node of the wireless home mesh network, (ii) a checksum of the encrypted pass-phrase, (iii) a public key of the wireless node, and (iv) a checksum of the public key of the wireless node, and (2) receiving a second message, the second message including a code to indicate whether the wireless node has been successfully authenticated along with the challenge text verification process to ensure the message was not tampered or sent by another node.

  • Patent number: 8861445
    Abstract: An embodiment is a technique to use a single radio for multi-channel wireless communication. A local device having a local channel table operates on a common channel in a multi-channel wireless network having a plurality of network devices to perform management, control, and discovery functions using a single radio. A data session channel is negotiated with a remote device having a remote channel table upon an initiation of a communication session using the local and remote channel tables on the common channel. Data packets are exchanged with the remote device using the data session channel in a data transmission mode.

  • Patent number: 8863173
    Abstract: A peer-to-peer (P2P) application which can be applied to TVs. The P2P application promotes a social networking aspect by allowing devices connecting to either the home mesh network and/or Internet to share contents and create common-interest channels. The P2P application does not require support from network infrastructure (e.g., no central servers), and consequently is extremely cost-effective and easy to deploy. The distributed nature of this system allows users to join or leave the network at will. It takes advantage of the local home mesh network connectivity, or existing Internet connections. A participant that tunes into a broadcast on an Internet channel is not only downloading a video stream, but also uploading it to other participants watching the program. Data mining systems capture user preferences and create personalized Internet channels on the TV using the P2P network.
