Abstract

A remote controlling method including the steps of storing the remote controller code of respective television brands in a first memory of a transmission IC, checking the input of dual keys for appliance brand selection to access the remote controller code data previously stored in the first memory, setting a data format and carrier dividing ratio according to the selected remote controller code data after the access operation so as to output them as channel-up data, storing the selected remote controller data in a second memory if the dual key input is released during the channel-up data output, and transmitting data suitable for the selected remote controller code with respect to a key input after the data storage.

Claims

1. A remote controlling method comprising the steps of:

pre-storing remote controller data codes of respective appliance brands in a ROM of a transmission IC;

checking for operation of dual keys indicative of appliance brand selection to thereby access one of the remote controller data codes previously stored in the ROM and produce a selected remote controller data code;

setting a data format and a carrier dividing ratio according to the selected remote controller data code so as to output the set data format and carrier dividing ratio as channel data;

storing said selected remote controller data in a RAM when said duel key input is released during the output of the channel data; and

transmitting after said storing step, data suitable for the selected remote controller code in response to a key input after said data storage.

2. The remote controlling method as claimed in claim 1, wherein said dual keys indicative of appliance brand selection comprise two designated keys of a keypad.

3. A method of remote controlling a particular brand appliance, said method comprising the steps of:

(a) pre-storing a plurality of remote controller data codes, each of said remote controller data codes corressponding to a different brand appliance, in a remote controller;

(b) determining whether two designated keys of the remote controller are being simultaneously activated, wherein one of said designated keys corresponds to the respective particular brand appliance;

(c) accessing, when said determining step (b) determines that the two designated keys are being simultaneously activated, one of remote controller data codes which is associated with the one of said designated keys; and

(d) transmitting data corresponding to the accessed one of said remote controller data codes to thereby control the particular brand appliance.

4. The method as defined in claim 3, further comprising the step of:

(e) setting a data format and a carrier dividing ratio according to the accessed one of said remote controller data codes,

wherein the data transmitted during a step (d) corresponds to the set data format and carrier dividing ratio.

5. The method as defined in claim 4, further comprising the step of (f) storing the data controlling the particular brand appliance.

6. The method as defined in claim 5, wherein said data stored in step (f), which corresponds to the particular brand appliance, is transmitted after activation of a preset key.

7. The method as defined in claim 6, wherein activation of the preset key occurs after step (b).
