Remote control system
First Claim
1. A remote control device for use in a communication coverage area wherein a plurality of remote control devices and remote control receivers may be operating simultaneously, for remotely controlling a remote control receiver operating in said area, the device comprising:
- input elements for providing electrical control signals;
a transmitter;
a processing device arranged for receiving the control signals from the input elements and for providing a coded signal to the transmitter, said coded signal being coded with a repeating frame format, wherein each frame comprises a number of data packets each contained in subsequent time slots, and wherein each data packet comprise a time slot identifier identifying the time slot in which the data packet is contained;
a receiver connected to the processing device, the processing device being arranged to obtain a time slot identifier from the data packets received by the receiver; and
a timing device connected to the processing device, whereby the processing device is arranged to control the timing of the coded signal provided to the transmitter, the processing device being arranged for receiving time slot identifiers from other remote control devices in the area, and for updating a billboard register, indicating presence of activity within a recently passed period of time, of remote control devices associated with each time slot number.

Abstract
The invention relates to a remote control system wherein a plurality of remote control devices and remote control receivers may be operating simultaneously. A remote control device comprises input elements for providing electrical control signals, a transmitter, and a processing device arranged for receiving the control signals from the input elements, providing a coded signal to the transmitter, said signal being coded with a repeating frame format, wherein each frame comprises a number of data packets each contained in subsequent time slots, and wherein each data packet comprises a time slot identifier identifying the time slot in which the data packet is contained. A remote control receiver is arranged for decoding a signal having a corresponding repeating frame format. The invention provides simple and reliable operation, synchronizing, addressing and connection functions, high bandwidth utilization and high tolerance towards disturbances, interference and communication obstructions. The invention may advantageously be used for remotely controlling objects for playing or amusement, such as controllable toys and model vehicles.
