The method comprising arranging a plurality of controllable devices into a plurality of groups; determining at least one link quality value for at least one device associated with the plurality of groups; calculating a proximity factor for the plurality of groups of controllable devices based at least partly on the determined at least one link quality value; comparing proximity factors for the plurality of groups of and selecting the group of controllable devices comprising a favorable proximity factor to be controlled by the RF controller device.

Abstract: A radio frequency (RF) remote controller device comprises radio frequency (RF) circuitry operably coupled to an antenna arrangement and arranged to transmit and receive RF signals to and from controllable devices. The RF remote controller device further comprises signal process logic operably coupled to the RF circuitry and to a user interface. The antenna arrangement is arranged to comprise a directivity characteristic. The signal processing logic upon receipt of a command input from the user interface, is arranged to: determine at least one link quality value that is at least partly dependent upon the directivity characteristic for the at least one controllable device; and select the controllable device for remote controlling based on the determined at least one link quality value.

Abstract: A controller node for an entertainment control network, comprises controller logic arranged to be paired with at least one controlled device over a wireless interface. The controller logic is further arranged to provide pairing information for the at lease one controlled device with which it is paired to a further node within the entertainment control network.

Abstract: A data communication network. The network includes a transmitter unit for transmitting data and a receiver unit for receiving data from the transmitter unit. The network has two or more data channels via which data may be transmitted by the transmitter unit to the receiver unit. The receiver unit includes a receiver channel selection unit for selecting a reception channel from the at least two data channels. The receiver channel selection unit operates independent from a selection of a transmission channel by a transmission channel selection unit in the transmitter unit. The transmission channel selection unit is arranged to select a transmission channel from the at least two data channels to transmit data to the receiver unit.

Abstract: A device for transmitting data in a wideband wireless network. The device may include a transmitter for transmitting data via a channel of the wideband wireless network, the transmitter is arranged to start the transmitting in response to a start signal. A first transmission controller is connected to the transmitter, for controlling transmission of data by the transmitter. The transmission controller includes an energy detector for detecting the amount of energy in the channel. The energy detector is arranged to repeat the detecting in response to a repeat signal. A comparator is connected to an output of the energy detector and to a control input of the transmitter. The comparator is arranged to compare the detected amount of energy with an energy threshold, to output the repeat signal to the energy detector in case the detected amount of energy exceeds the energy threshold; and to output the start signal to the transmitter when the detected amount of energy is below the energy threshold.

Abstract: A multi-channel sniffer system is provided that includes a reference sniffer comprising a reference clock, secondary sniffers, each having a secondary clock and operable to receive data units from a communication channel, and a synchronization unit connected to the reference sniffer and the secondary sniffers and adapted to switch the reference sniffer and each of the secondary sniffers into a first synchronization mode and to enable a data communication between the reference sniffer and the secondary sniffers. The reference sniffer sends a first delimiting data unit indicating a current reference clock time value to the secondary sniffers when in first synchronization mode. Each of the at least one secondary sniffers is adapted to receive the first delimiting data unit and set a current secondary clock time value of its secondary clock to the current reference clock value.

Abstract: An information processing device comprises a memory carrying a program, and a processor capable of executing the program. The program instructs the processor to determine whether a selected identifier is contained in a set of identifiers, and, if the processor has determined that the identifier is contained in the set of identifiers, to execute a patch instruction identified by the identifier, and, if the processor has determined that the identifier is not contained in the set of identifiers, to execute an original instruction identified by the identifier. The memory may comprise a read-only memory (ROM) and a random access memory (RAM), the ROM carrying the original instruction and the RAM carrying the patch instruction and the set of identifiers. A method of executing a program on an information processing device and a method of modifying a program on an information processing device are also disclosed.
