Abstract
An apparatus and a method for remote transmission adapted to a remote controller transmitting a radiated remote control optical signal for controlling remotely controlled appliances. Product control data or company control data, and signal formats corresponding to respective keys are stored in a memory in advance, so that, whenever one key selection is inputted, respective control data corresponding to the inputted key are transmitted in accordance with the product signal format.
Claims14
A remote transmitting apparatus in a remote controller for transmitting a remote control signal, comprising:
- key input means for receiving a plurality of control commands;
- microtransmitter means comprising memory means having a ROM and a RAM, said ROM storing a plurality of signal formats and a plurality of appliance control data strings for controlling electronic appliances in response to a user's control commands, whereby, responsive to each of said control commands, one appliance control data string stored in said ROM is read out and temporarily stored in said RAM, then one signal format stored in said ROM and corresponding to said one appliance control data string is read out and stored in said RAM, then one remote control data string corresponding to said appliance control data string and said signal format stored in said RAM is generated in dependence upon a clock signal, and then another appliance control data string stored in said ROM is read out and temporarily stored in said RAM, and another corresponding signal format stored in said ROM is read out and stored in said RAM to generate another corresponding remote control data string until a remote control data string corresponding to each control command is generated;
- and
- means for converting the output of said micro-transmitter means into an optical signal, and for transmitting said optical signal so as to simultaneously control plural electronic appliances.

A method for sequentially controlling plural electronic appliances using a remote controller having a key input a micro-transmitter having a ROM and a RAM, and an optical signal converter, comprising the steps of:
- receiving a plurality of user's key inputs;
- generating a remote control data string corresponding to each said user's key input whereby, corresponding to each said user's key input, an appliance control data string stored in said ROM is read out and temporarily stored in said RAM, then a signal format stored in said ROM and corresponding to said appliance control data string is read out and stored in said RAM, then one remote control data string corresponding to said appliance control data string and said signal format stored in said RAM is generated in dependence upon a clock signal until remote control data strings corresponding to each user's key input are generated;
- and
- converting and transmitting plural remote control data strings in the form of optical signals so as to simultaneously control said plural electronic appliances.
1 more element
A remote control transmitter for sequentially controlling a plurality of electronic appliances, comprising:
- key matrix means for entering a plurality of command signals from a user;
- and
- transmitter means comprising memory means for storing a plurality of transmission formats respectively representative of format structures for said plurality of electronic appliances, and a plurality of appliance control data strings having custom codes corresponding to specific ones of the electronic appliances and command codes corresponding to each said command signal, for transmitting a single remote control signal in response to each said command signal to sequentially enable a plurality of electronic appliances, said remote control signals controlling said plurality of electronic appliances with a sequence of data control blocks each having a selected appliance control data string and a selected transmission format for simultaneously controlling selected electronic appliances in dependence upon said command signals.
A remote control transmitter for sequentially controlling a plurality of electronic appliances, comprising:
- key matrix means for receiving a plurality of command signals from a user via a plurality of selection keys;
- and
- transmitter means for transmitting at least one single remote control signal having a sequence of data control blocks for sequentially controlling a plurality of electronic appliances in dependence upon said command signals from said user, said transmitter means comprising:
- first memory means for storing a plurality of transmission formats respectively representative of a format structure for each of said plurality of electronic appliances, a plurality of appliance control data strings having custom codes corresponding to specific ones of the electronic appliances and command codes corresponding to said plurality of command signals from said user, and an operating program for enabling a sequential reading of said transmission formats and said appliance control data strings in dependence upon reception of said command signals;
- second memory means for temporarily storing said transmission formats and said appliance control data strings from said first memory means;
- means for generating said single remote control signal in said sequence of data control blocks having selected appliance control data strings and selected transmission formats for sequentially controlling a plurality of electronic appliances as dependence upon a clock signal;
- and
- means for transmitting said single remote control signal in an infrared signal.
