20160006575 | MULTI-TIER WIRELESS HOME MESH NETWORK WITH A SECURE NETWORK DISCOVERY PROTOCOL - 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. | 01-07-2016 |
20130322625 | METHOD AND APPARATUS FOR PROTECTING THE TRANSFER OF DATA - According to one embodiment, a method of descrambling digital multimedia content starts by sending an out-of-band request for encrypted control data to a headend. A descrambler integrated circuit may then receive digital program data in a scrambled format and the encrypted control data. The encrypted control data may then be decrypted entirely within the descrambler integrated circuit using a multiple-step decryption process starting with a unique key permanently stored in the descrambler integrate circuit and using the partial decryption of control data from the previous decryption step to generate a key to decrypt subsequent encrypted control data. The scrambled digital program data may then be descrambled in the descrambler integrated circuit using the decrypted control data from the last decryption step. Other embodiments are described. | 12-05-2013 |
20130322294 | Method and Apparatus for a Wireless Home Mesh Network with Network Topology Visualizer - An apparatus and method for a wireless home mesh network with a network topology visualizer is described. In one embodiment, the method may include collecting node topology information by a node of a wireless home mesh network, where the node topology information includes a list of neighbor nodes for the node. Thereafter, a communication socket is opened, and a node topology packet, including a lust of neighbor nodes, is transmitted in order to produce a global network topology map. Other embodiments are described and claimed. | 12-05-2013 |
20110072478 | BANDWIDTH REPORTING FOR TELEVISIONS - Techniques for reporting bandwidth in televisions include displaying bandwidth information for receiving one or more instances of the content and receiving a selection of a given instance of the content in response to the displayed bandwidth information. In addition, the techniques include receiving bandwidth usage history for one or more networks and displaying the bandwidth usage history. | 03-24-2011 |
20100332985 | GRAPHICAL USER INTERFACE FOR A DEVICE HAVING MULTIPLE INPUT AND OUTPUT NODES - A graphical user interface (GUI) is described. The GUI includes first GUI elements that provide a visual representation of the nodes of an audio/video device. In response to user input, a signal is caused to be routed between nodes by manipulating circuitry within the audio/video device. Second GUI elements provide a visual representation of the signals being routed within the electronic device between pairs of first GUI elements (e.g., between nodes). As a result, the user can readily understand which nodes are connected to each other. Thus, for example, a user can easily visualize which source node is providing input to a target node and, by selecting the appropriate GUI elements, can just as easily switch from one source to another or from one target to another. | 12-30-2010 |
20100159855 | TECHNIQUES FOR PRE-DISTORTING TRANSMITTED SIGNALS FOR A TRANSMITTER DEVICE - Techniques for sending and receiving signals include pre-distorting signals before transmission across a communication path. The signals are pre-distorted as a function of a distortion on the communication path. In one embodiments, transmitter a broadcasts to receiver b and there is also a transmitter b broadcasting to receiver a. This return channel enables both transmitters a and b to have a priori information regarding the transmission medium and path the signal takes. In this way, the nature of the distortion or interference is known to the transmitter, therefore, it pre-distorts the transmitted signal to compensate for the receiver exceeding its capabilities in recovering signal. | 06-24-2010 |
20100118209 | SYSTEM AND METHOD FOR POWER SAVING VIA CONTEXT BASED COMMUNICATION - A system and method for generating remote control signals to control a device while conserving power. The method includes receiving an input command for communication to the device to be controlled and determining a use context based on the input command. Based on the context determination, communication over an infrared transmitter and a radio frequency transmitter is adjusted for power savings where one transmitter is typically active. The input command may then be sent via the infrared transmitter or the radio frequency transmitter. At the completion of the usage mode, the operational states of the transmitters can be switched. | 05-13-2010 |
20080239159 | Video Content Identification Using Scene Change Signatures from Downscaled Images - Apparatus for identifying video content includes a scene detector to detect a plurality of consecutive scenes in the video content. The video content may include a video program and an advertisement contained within the video program. A signature generator determines a scene change signature for each of the plurality of consecutive scenes. A content identifier provides the plurality of scene change signatures to a comparator that compares the plurality of scene change signatures to a database having a plurality of video content items to identify the video program. The database includes an ordered plurality of previously determined scene change signatures for each item of video content in the database. The content identifier receives an identification of the video content from the comparator. The content identifier may further receive information related to a position of the plurality of scene change signatures within the ordered plurality of previously determined scene change signatures. | 10-02-2008 |
