METHOD OF, AND SYSTEM FOR, TRANSFERRING SECURE DATA

摘要

A method of transferring secure data in a remote control system including a remote controller (12) and an apparatus (10) which is operable in response to commands relayed by way of the remote controller. The apparatus has a receiver (38) for receiving transmissions from the remote controller (12), the information from the transmissions being stored in a storage device (42). The remote controller has a transmitter (26), a memory (22) for storing secure data and commands and a keypad (24). The transmitter (26) is controlled so that in response to a user wishing to transfer secure data to the user apparatus (10), it transmits this data at a power level lower than that which is normally used for sending other commands. The link between the remote controller (12) and the user apparatus (10) may be wireless or infra-red.
