摘要： A remote control device for a separate electronic device to be controlled has a secondary display screen, at least one user-input mechanism, and at least one microprocessor running a user interface application for use in providing control over operation of the electronic device to be controlled. The user interface application causes a user interface to be displayed on the display screen of the remote control device, and the user interface displayed on the display screen graphically mirrors a corresponding user interface independently run by the electronic device to be controlled. The remote control device also has a transmitter and receiver mounted within the body enabling a two-way wireless communication link to be established with the electronic device to be controlled. Apparatus and a method for controlling operation of a media display system are also described.

摘要： During each node's awake period, each node multicasts the relative time or slot of their next awake period (beaconing interval) to all neighboring nodes. This enables each node to intelligently and independently schedule the time slot of its next transmission based on the beaconing intervals of the nodes it has heard from. During each active (awake) interval, a node builds statistics of the future transmission/receive times of its neighbors and uses them to determine its next transmission time. In one proposed implementation, at the end of an active interval, a node picks the time slot with the highest counter for its next transmission. In another proposed implementation, at the end of an active interval, a node picks one of the slots with a weighted probability; the weight of each slot is proportional with the value of the counter associated with the slot.

摘要： Energy-efficient discovery techniques are provided for a client node to discover at least one peer provider node in an ad hoc network. For example, the client node can be configured to turn on its first ad hoc interface while in a discovery mode to establish a channel for a first time period. The client node can then transmit a first beacon to advertise its presence to other nodes within the transmission range of the client node to acquire service information from at least one of a plurality of prospective peer provider nodes within the transmission range of the client node. At least one of the prospective peer provider nodes is configured to turn on its second ad hoc interface for a second period of time to listen for beacons from other nodes. The second period of time is less than or equal to the first period of time.

摘要： A disclosed content rights management system defines a content usage policy via a conditional rule set contained in metadata. The conditional rule set is correlated to at least one second content. An access control manager determines, dynamically, access rights conferrable to a user device or a server, based on the content usage policy and user history parameters. The embodiments may confer limited access rights for a first activity by a user device, or by a server, with respect to the protected content and the second content, and block a second activity with respect to the protected content and the second content, in response to determining that the request for the second content, in conjunction with the user history parameters, does not comply with the conditional rule set for the second activity.

摘要： A method and apparatus for downloading content within a video-on-demand system is provided herein. During operation a Video Home Office (VHO) will cache a subset of the Video Service Office (VSO) content. When a user requests content that is not stored on the VHO, the VHO will request that content from another VHO or the VSO. In order to reduce the additional network load imposed during item forwarding while attempting to balance the total load on all the links interconnecting the VSO and VHOs, recorded traffic history metrics are used to predict their future or current traffic. A VHO or VSO is chosen for fetching the content that will result in the lowest predicted traffic on the interconnecting links.

摘要： A method and apparatus for allocating resources to a node in an ad-hoc communication system is provided herein. During operation, nodes of the system will receive resource allocations from their parent node. The resource allocation comprises a portion of available resources that may vary in size. Each node will determine the resource needs for its children nodes only and then dynamically assign resources to them. The resources assigned to the children nodes comprise a portion of the resources assigned to the node by its parent node. Additionally, knowledge as to how the children further allocate resources to their own children is not known by the parent, however, the children nodes must allocate a portion of their resource to their children nodes.

摘要： A method, apparatus (100) and system (200) for altering the playback speed of recorded content (105) to match a target syllable rate is provided. A user may enter a desired, target playback syllable rate through a user interface (101), such as a keypad or touch screen. Alternatively, the target playback syllable rate may be determined from identification of the source of the recorded content (105). An actual playback syllable rate (106) associated with the recorded content (105) is then determined. The recorded content (105) is then altered, by time domain harmonic scaling in one embodiment, such that the altered playback speed (109) substantially matches the target playback syllable rate. In so doing, a listener is able to receive recorded content (105) at a faster or slower rate than it is produced. Elements that may compromise the intelligibility of the recorded content (105), including distortion (114), background noise (113), ambient noise (117) and audible intonations (115), may be measured such that the target playback syllable rate may be compensated.

摘要： During operation, a node (104) will determine a particular probability of achieving a successful location. When battery resources are below a threshold the node will utilize a minimum probability for success in determining how many time-slots to collect RSSI measurements. However, if battery resources are above the threshold, a higher probability of achieving a successful location than the minimum may be utilized. After the particular probability of achieving a successful location is determined, a number of time-slots (L) are determined. L comprises a number of time slots that the node must remain awake for to achieve the particular probability of achieving a successful location. The node will then remain awake for L time slots, and compute a location based on measurements taken within those L time slots.
