摘要:
A method and apparatus for operation of a node within a mobile ad hoc cognitive radio network is provided. The method includes sensing at least one assigned communications channel. Sensing at least one assigned communications channel includes measuring a value of at least one parameter corresponding to the communications channel. The method further includes comparing the measured value of the at least one parameter with a set of stored values of the at least one parameter to determine a change in the measured values. Finally a sleep mode of the node is activated for a time period, wherein the time period is determined using the change in the measured values.

摘要:
A communications system and method for exchanging spectrum usage information through a drop box (100) includes one or more central stations (101) that defines a region of operation. A central drop box (102) is associated with the central station (101) for providing a database of spectrum usage information. Stations (103, 105, 107) using the communications system may submit information regarding spectrum usage to the central drop box (102) that affects the region of operation (109, 115) for providing the most efficient and non-interfering uses of the frequency spectrum.

摘要:
A method of operation of a node for multi-band communication routing within a wireless communication system comprises communicating a communication session on a default route within an identified quality of service objective on a first frequency band; broadcasting, on a second frequency band, one or more route discovery messages at each of a plurality of sets of transmission variables; storing one or more alternate route table entries in a route table, wherein each of the one or more alternate route table entries are indexed by each of the plurality of sets of transmission variables that are at least within the quality of service objective; selecting a stored alternate route that is at least within the quality of service objective of the communication session on the second frequency band; and switching the communication session to operate using the transmission variables related to the selected alternate route.

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:
A system and method is configured to receive a single video stream, synchronized with multiple audio streams, from a content producer. In addition, viewer information is received from a client device; and viewer profile information is retrieved. The client device is provided instructions to switch to one of the multiple audio streams that closely correspond to the viewer profile information, while maintaining the same video stream and synchronization.
