KR960027280A - Automatic tuning device using scan key and method - Google Patents

Abstract

The present invention relates to an automatic tuning apparatus using a scan key and a method thereof, and more particularly, to use a scan key among a plurality of preset broadcast channels in a system capable of storing a desired broadcast in a memory means using a preset button. The preset broadcast channels can be tuned in sequence so that the corresponding broadcast channels can be tuned automatically.

A characteristic configuration includes a key input unit including a plurality of preset keys for tuning to a desired broadcast channel and shortening and storing the desired broadcast channel, and a scan key for searching for and storing a broadcast channel shortened and stored by all the presetters; According to the selected value of the key input unit, a microprocessor that sequentially reads a plurality of broadcast channels already stored in the memory means by a preset key and sequentially receives and outputs them for a predetermined time. Is the scan key input to the key input unit? The first step of checking and the step of checking whether the preset key is input again if the scan key is not the scan key of the first step, and the plurality of preset channels shortened by a plurality of preset keys to which the scan key is input Preset key while receiving and outputting corresponding broadcasting channels in order for a certain time Waiting for input, if the preset key is input in the second step, and the preset key is input in the second step, the receiver continuously receives and outputs the broadcast of the corresponding channel that is currently received and processed. The third step is to wait for the scan key to be input.

Claims (2)

It includes a plurality of preset keys (K1 to K6) for tuning and storing desired broadcasting channels in one key, and a scan key (K7) for searching and storing broadcast channels shortened and stored by all the preset keys. And a microprocessor 20 which sequentially reads a plurality of broadcast channels that are already short-stored in the memory means with a preset key according to the selection key value of the key input unit, and sequentially receives and outputs them for a predetermined time. Automatic tuning device using a scan key characterized in that. A channel search method of an audio system having a scan key for automatic search and a plurality of preset keys for short-term storage in a key input means, the first step of checking whether a scan key is input from the key input means (S1) If the check key of the first step is not the scan key, the method proceeds to the step of checking whether the preset key is input again, and when the scan key is input, a plurality of preset channels are shortened and stored for a predetermined time by reading the preset key The second step (S2) of waiting for the preset to be input while receiving and outputting the corresponding broadcast channel, and if the preset key is input in the second step, continues to receive the broadcast of the corresponding channel currently received and output-processed. If the output is processed and the preset key is not input, the process returns to the first step (S1) and consists of the third step (S3 to S4) waiting for the scan key to be input. Automatic tuning method using the scan key. ※ Note: The disclosure is based on the initial application.
