Description

Method of processing broadcast channel according to MSM key operation {Method Processing Broadcast Channel in Accordance with Best Station Memory Key Operation}

The present invention relates to a broadcast channel processing method according to a BSM key operation, and more particularly, to a method of processing a broadcast channel according to a Best Station Memory key operation.

In general, the best station storage method used in a car audio system automatically selects a radio broadcast frequency belonging to a specific broadcast band (AM, FM1, FM2, etc.) transmitted from a broadcasting station according to electric field strength and stores it in a preset memory.

That is, in the conventional best station storage method, in order to automatically select radio broadcast frequencies belonging to a specific broadcast band according to electric field strength, a band switching button of a car audio system is operated to correspond to a specific broadcast frequency according to the selected FM broadcast band. If the Best Station Memory (BSM) button is operated when an FM radio station is output, a station with a high electric field strength, that is, a station with good reception sensitivity, is selected first from the FM station belonging to the FM station. In order to automatically save them in the preset memory of the car audio system.

In this case, the number of FM broadcast frequencies stored in the preset memory may vary depending on the memory capacity, and is limited to about six per one broadcast band.

In addition, when the driver selects one of the preset buttons assigned to 1 to 6 corresponding to each of the six FM broadcast frequencies sequentially stored in the preset memory, the driver selects one of the six preset FM buttons stored in the preset memory. Provides a radio broadcast of the FM broadcast frequency corresponding to the number.

However, the conventional best station storage method can automatically store the broadcast frequency in the preset memory only in a specific broadcast band, so that the BSM button and the preset button need to be operated separately whenever the broadcast band is changed.

That is, in order to listen to the AM broadcast automatically by selecting the AM broadcast frequency by the best station memory method, the driver must operate the BSM button and the preset button again after selecting the AM broadcast band by changing the band switching button. There is discomfort.

In addition, when the user operates the BSM button again to listen to a channel other than the broadcast channel stored in the preset memory, the same broadcast channel as the previously stored broadcast channel is again stored in the preset memory unless the vehicle crosses the state / province / country boundary. There is a limit in providing convenience to the user because it is stored redundantly in the.

The present invention was created in view of the above limitations, and when a BSM (Best Station Memory) key operation for automatically storing a broadcast having good reception sensitivity is continuously performed, the same broadcast channel as the previously stored broadcast channel is duplicated and stored. It is an object of the present invention to provide a broadcasting channel processing method according to a BSM key manipulation to prevent processing.

In order to achieve the above object, a broadcast channel processing method according to a BSM key operation according to an aspect of the present invention comprises the steps of determining whether the search of the broadcast channel according to the user's operation is the initial search or continuous search; As a result of the determination, when the search of the broadcast channel is a continuous search, the number of times of Best Station Memory (BSM) key input (c) is increased and stored, the number of preset memories (n) in which the broadcast channel is stored, and the confirmed preset Determining whether n broadcast channels are the same broadcast channel sequentially from the highest sensitivity among the n broadcast channels stored in the memory and the broadcast channels in which the broadcast bands are searched for one period and arranged; And as a result of the determination, in the case of the same broadcast channel, preset broadcast channels from (n * c) + 1st broadcast channel to (n * c) + nth based on the highest sensitivity among broadcast channels arranged in order of reception sensitivity Storing in the.

According to the present invention, instead of continuously storing the same frequency when the BSM key is continuously operated by the user, only the other frequencies except the same frequency can be stored each time the BSM key is operated, so that the user can receive only the BSM key. Allows you to listen to several good radio stations.

Advantages and features of the present invention and methods for achieving them will be apparent with reference to the embodiments described below in detail with the accompanying drawings. The present invention may, however, be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. And is intended to enable a person skilled in the art to readily understand the scope of the invention, and the invention is defined by the claims. It is to be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. In the present specification, the singular form includes plural forms unless otherwise specified in the specification. It is noted that " comprises, " or "comprising," as used herein, means the presence or absence of one or more other components, steps, operations, and / Do not exclude the addition.

Hereinafter, a broadcast channel processing method according to a BSM key operation according to an embodiment of the present invention will be described with reference to FIG. 1. 1 is a flowchart illustrating a broadcast channel processing method according to a BSM key operation according to an embodiment of the present invention.

The present invention relates to a method of processing a broadcast channel according to a BSM key operation. The present invention searches for a broadcast channel of a best station according to a user's best BSM key operation and stores it in a preset memory. If there is no preferred broadcasting channel among the stored broadcasting channels in the preset memory and wants to listen to other broadcasting channels other than the stored broadcasting channels, that is, when the BSM key is operated again by the user, the broadcasting channel is rescanned and the previously stored broadcasting channel among the rescanned broadcasting channels is desired. If there is a broadcast channel different from the channel, it is stored to provide a user with a good reception sensitivity without duplication of the broadcast channel.

As described above, in the method for processing a broadcast channel according to a BSM key manipulation according to the present invention, as shown in FIG. 1, it is first determined whether a search for a broadcast channel according to a user's operation is an initial search or a continuous search (S100).

For example, if the BSM key is operated for longer than a preset time by the user (if it is a long key input), the search of the broadcast channel is determined to be an initial search, and if the BSM key is operated for less than a preset time ( If a short key is input), the search of the broadcast channel is determined to be a continuous search.

As a result of the determination, when the search of the broadcast channel is the initial search, the operation number c of the BSM key is initialized and stored (S101). When the determination of the broadcast channel is the continuous search, the number of operations of the stored BSM key ( c) increases by 1 and stores (S102).

The broadcast band is searched for one cycle to sort the broadcast channels in order of reception sensitivity (S103), and it is determined whether the number of operations (c) of the stored BSM keys is greater than or equal to 1 (S104).

As a result of the determination, when the number of operations (c) of the stored BSM key is greater than or equal to 1, the number (n) of the preset memories stored in the broadcast channel is checked (S105), and n broadcast channels stored in the identified preset memory, It is determined whether the n broadcast channels are sequentially the same broadcast channel from the highest sensitivity among the aligned broadcast channels (S106).

As a result, when the n broadcast channels are sequentially the same from the highest sensitivity among the n broadcast channels and the aligned broadcast channels stored in the preset memory, based on the highest sensitivity among the broadcast channels arranged in the receive sensitivity order (n * c) The broadcasting channel from the + 1th broadcasting channel to the (n * c) + nth broadcasting station is stored in the preset memory (S107).

However, as a result of determining in step S104, when the number of operations (c) of the stored BSM key is less than 1, the number (n) of preset memories capable of storing broadcast channels is checked (S108), and the received sensitivity is arranged in order. The n broadcast channels are sequentially stored in the preset memory from the highest reception sensitivity among the broadcast channels (S109).

Further, as a result of the determination in step S106, when the n broadcast channels are not the same broadcast channel sequentially from the highest sensitivity among the broadcast channels aligned with the n broadcast channels stored in the preset memory, that is, different from the preset ratio (90%) or more. In the case of the channel, n broadcast channels are sequentially stored in the preset memory starting with the highest reception sensitivity among the broadcast channels arranged in the receiving sensitivity order (S109).

As described above, according to the present invention, instead of continuing to store the same frequency when the BSM key is operated continuously by the user, the user saves only the other frequency except the same frequency as the pre-stored frequency whenever the BSM key is operated. Allows the BSM key operation to listen to multiple frequencies with good reception.

Although the configuration of the present invention has been described in detail with reference to the preferred embodiments and the accompanying drawings, this is only an example, and various modifications are possible within the scope without departing from the spirit of the present invention. Therefore, the scope of the present invention should not be limited by the illustrated embodiments, but should be determined by the scope of the appended claims and equivalents thereof.
