Abstract:
System, method and computer program product for determining a polling schedule for a remote control, are described. A multimedia device collects usage data that identifies when the multimedia device is in use. The probability that the multimedia device is in use for a particular time is determined based on the usage data. A polling schedule is generated based on the usage probability such that the periods in the polling schedule vary according to the usage probability to minimize energy consumption. The polling schedule is then transmitted to the remote control where the remote control polls the multimedia device according to the polling schedule.
Abstract:
A standby power controller that is adapted to remove the electric power from the attached devices when an attached television is determined to be not in use. The controller includes a data communication link adapted to provide data communication with a co-located set top box so as to allow the transfer of usage information from the set top box to th e standby power controller.
Abstract:
Operations for a WLAN-capable remote control device and a controlled device are disclosed. A first network device (e.g., remote control) may receive a user input for controlling operation of a second network device (e.g., controlled device) of a communication network. The first network device may transition to an active operating state in response to receiving the user input. The first network device may transmit the first user input to the second network device. The first network device may exit the active operating state in response to successfully transmitting the first user input to the second network device.

Abstract:
The invention describes a method of actuating a switch (S) between a device (Di) to be controlled and a power supply (P), which method comprises the steps of generating a first electrical signal (14) in a remote control unit (10) and converting the first electrical signal (14) into electromagnetic radiation (EM) by means of a first transmitting antenna (Ti) of the remote control unit (10). A first detecting antenna (Ri) of a remote control interface module (20) of the device (Di) to be controlled detects the electromagnetic radiation (EM) to obtain a second electrical signal (24), which is passively converted into a switch actuating signal (25). The switch actuating signal (25) is actuated to switch the device (Di) to be controlled between an operating mode in which current is drawn from the power supply (P) by the device (Di) during operation, and an inactive mode in which the device (Di) is completely disconnected from the power supply (P) so that no current is drawn by the device (Di). The invention further describes a system (1) for actuating a switch (S) between a device (Di) to be controlled and a power supply (P). The invention also describes a remote control interface module (20) and a remote control unit (10).
Abstract:
The disclosed embodiments relate to an electronic device configured to receive infra red (IR) signals. The electronic device comprises a first IR decoder configured to decode the IR signals when the electronic device is operating in a first power mode, and a second IR decoder configured to decode the IR signals when the video unit is operating in a second power mode.
