REMOTE CONTROL METHOD AND DEVICE

摘要

A togglebit learning remote control (TLRC) is described. Prior art "learning" remote control transmitters can neither learn nor transmit data formats with "toggle bits". The aim is to develop an infra-red remote control transmitter (TLRC) which both understands the former external formats and those with toggle bits and different carrier frequency ranges and transmits these data formats to the appropriate devices with or without a toggle bit. A device for receiving and transmitting infra-red formats consisting of an infra-red receiver (IR) with a fast microprocessor (MP) and/or with two carrier frequency oscillators (LO) and (HO) to generate two modulation frequencies and/or two infra-red receivers (LF) and (HF). An externally formatted data word with toggle bits is subjected, after being read in at least twice, to a comparison inside the microprocessor (MP) from which the presence of toggle bits and their number and position and the carrier frequency of the data word are found. Application to remotely controllable electrical devices.
