The present invention relates to a broadcasting frequency tuning method, and in particular, when a broadcast signal of a predetermined broadcast station is moved to another broadcast area, a broadcast signal of a broadcast station broadcasting the same signal as the received broadcast signal in the moved broadcast area is moved. A broadcast frequency tuning method of a broadcast receiving terminal using a mobile phone that automatically receives.

In recent years, as the size of electronic components is reduced and the power consumption thereof is reduced, broadcast receiving terminals for receiving broadcast signals are becoming smaller. However, such a broadcast receiving terminal is inconvenient to tune to another channel because the broadcast receiving terminal does not receive a corresponding frequency when it is out of the corresponding broadcast area while receiving a broadcast of a specific channel.

As an alternative for solving the above problems, a method of automatically scanning when the broadcast signal being received by the broadcast receiving terminal is cut off is used. However, this method not only does not continuously receive the broadcast signal of the broadcasting station broadcasting the same signal, but also the radio wave is not uniformly cut off when the broadcast receiving terminal is separated from the transmitting station. Even if the radio is temporarily interrupted, this is not a fundamental solution.

The present invention automatically receives a broadcast signal of a broadcast station that broadcasts the same signal as the received broadcast signal in a shifted broadcast area when the broadcast signal of a predetermined broadcast station is moved to a broadcast area where the broadcast signal is not received. An object of the present invention is to provide a broadcast frequency tuning method for a broadcast receiving terminal using a mobile phone.

Another object of the present invention is to provide a method of tuning a broadcast frequency by determining whether or not a communication signal transmitted from a base station can be received when reception of a broadcast signal of a predetermined broadcast station becomes impossible.

In order to achieve the above object, a broadcast frequency tuning method of a broadcast receiving terminal using a mobile phone according to the present invention includes broadcasting station information of a broadcast signal that can be received by a processor in a radio wave received by a mobile phone periodically communicating with a base station; Extracting frequency information and storing the frequency information in a memory; A second step of determining whether a broadcast signal currently being received by the broadcast receiving terminal is continuously received; A third step of continuously receiving a corresponding broadcast signal when the determination result of the second step is received; A fourth step of determining whether a broadcasting station that broadcasts the same broadcast signal as the received broadcast signal at a different frequency is stored in a memory, when it is not received as a result of the determination in the second step; If it is stored as a result of the determination of the fourth step, characterized in that the fifth step of receiving a broadcast signal of the other frequency.

In this case, the fourth step may include: a step 4-1 of determining whether the mobile phone communicates with the base station when the determination result of the second step is not received; A step 4-2 of extracting broadcasting station information and frequency information from the communication radio wave and storing it in a memory when the communication result is determined in step 4-1; Step 4-3 may be performed to determine whether a broadcast station that broadcasts the same broadcast signal as the broadcast signal currently received in the memory and the frequency information stored in the memory at a different frequency is stored in the memory. In addition, when it is not stored as a result of the determination of the fourth step, it is preferable to receive a broadcast signal at a frequency of a broadcast station that can be received.

Hereinafter, with reference to the accompanying drawings will be described in detail the present invention.

1 is a configuration example of a mobile phone integrated broadcast receiving terminal to which the present invention is applied. In the drawing, reference numeral 120 denotes a mobile phone capable of wireless communication with a base station, and reference numeral 130 denotes a broadcast receiving terminal capable of receiving broadcast signals such as TV, DMB, FM, and AM.

First, as a premise for carrying out the present invention, the base station is set so as to insert and transmit broadcast station information and frequency information of a broadcast signal that can be received by the base station in a communication radio wave.

The mobile phone 120 includes an antenna 121, an RF unit 122, a processor 123, a key 124, and the like to perform a wireless communication function through communication with a base station. At this time, the processor of the mobile phone 120 extracts broadcasting station information and frequency information from the received communication radio waves and stores them in the internal memory.

The broadcast receiving terminal 130 is composed of an antenna 131, a tuner 132, a decoder 133, and an output means 134 to perform a broadcast signal receiving function, which is transmitted to and received from a broadcast station. The included broadcast data is processed so that the user can watch or listen to it.

An interface is established between the mobile phone 120 and the broadcast receiving terminal 130 according to a separately set protocol. The broadcasting station information and the frequency information stored in the mobile phone 120 are transferred to the broadcast receiving terminal 130. Is provided. The broadcast receiving terminal 130 may include a separate controller (not shown) that manages the received broadcasting station information and frequency information.

At this time, the mobile phone 120 and the broadcast receiving terminal 130 may be integrated as one, as shown in Figure 1, the mobile phone 120 and the broadcast receiving terminal 130 is separated It can also be detachable, which can be connected via a separate interface cable.

2 is a flowchart illustrating a broadcast frequency tuning method of a broadcast receiving terminal using a mobile phone according to the present invention. That is, when a user moves to a broadcast area where a broadcast signal of a predetermined broadcast station is not received while receiving a broadcast signal of a broadcast station, the broadcast signal of a broadcast station broadcasting the same signal as the received broadcast signal in the shifted broadcast area. The present invention shows a method of tuning broadcast frequencies by determining whether communication signals transmitted from a base station can be received when not only can be automatically received but also broadcast signals cannot be received.

Referring to FIG. 2, the mobile phone extracts broadcast station information and frequency information of a broadcast signal that the processor can receive from communication waves received periodically communicating with a base station, and stores the broadcast station information and frequency information in the memory (S212 and S214).

Subsequently, when the user receives the broadcast signal of the corresponding frequency of the predetermined broadcast station stored in the memory, it is periodically determined whether the broadcast signal currently received by the broadcast receiving terminal is continuously received (S216 and S218).

As a result, when the broadcast signal is continuously received, the broadcast signal receiver continuously receives the corresponding broadcast signal (S220).

However, if it is determined that the broadcast signal is not received, the broadcast signal receiver determines whether the mobile phone communicates with the base station (S222). Here, the reason for determining whether the mobile phone communicates with the base station is to determine whether the broadcast signal is temporarily not received due to a tunnel or an obstacle, or whether the broadcast signal is not received by moving the broadcast area.

As a result of the determination in step S222, if the mobile phone does not communicate with the base station, it is fed back to step S218 and waits until the broadcast signal is received or can be communicated with the broadcast signal receiver. Broadcasting station information and frequency information are extracted from the receivable communication radio waves and stored in the memory (S224). At this time, when the feedback to the step S218 may be processed to wait until a predetermined time.

Subsequently, it is determined whether a broadcast station that broadcasts the same broadcast signal as the broadcast signal currently received by the broadcast receiving terminal at a different frequency is stored in the memory (S226).

As a result of the determination in step S226, if it is stored, the broadcast receiving terminal determines the stored frequency and receives the broadcast signal of the other frequency (S228, S230). That is, as the broadcast area moves, the broadcast signal of another frequency stored in the same broadcast station that can be received is received.

However, as a result of the determination in step S226, if not stored, the broadcast signal is received at a frequency of another predetermined broadcast station that can be received by the broadcast receiving terminal (S232, S234).

3A is a conceptual diagram of a broadcast station and frequency relationship of a broadcast signal that can be received for each broadcast zone according to the present invention, and FIG. 3B is an embodiment of a case where a broadcast zone is moved according to the present invention.

Referring to FIG. 3A, it is assumed that a broadcast area is divided into two A and B, and that a broadcasting station has three KBS, MBC, and SBS. KBS broadcaster fKA, MBC broadcaster fMA, SBS broadcaster fSA is assigned to the broadcast zone A, KBS broadcaster fKB, MBC broadcaster fMB, SBS broadcaster fSB to the broadcast band B Assume that it is allocated.

As shown in FIG. 3B, if the user is in aa position belonging to the broadcast zone A, the mobile phone extracts information of three broadcasting stations KBS, MBC, SBS and three frequencies of fKA, fMA, and fSA that can be received by the processor from the radio wave. Store in memory.

If the broadcast signal receiver moves to the bb position belonging to the broadcast zone B along the path of ① while receiving the broadcast signal at the fKA frequency of the KBS broadcasting station according to the user's operation at the aa position, the broadcast zone A is out of the broadcast zone A. The received broadcast signal is not received, and the mobile phone extracts information of three broadcasting stations, KBS, MBC, and SBS, and three frequencies of fKB, fMB, and fSB from communication radio waves, and stores them in a memory. Then, since the KBS broadcasting station for broadcasting the broadcast signal received at different frequencies is stored in the memory as the broadcast area is moved, the broadcast receiving terminal continuously receives the broadcast signal of the fKB frequency of the KBS broadcasting station.

According to the present invention, when a broadcast signal of a predetermined broadcast station is received while moving to a broadcast area where the broadcast signal of the predetermined broadcast station is not received, the broadcaster of the broadcast station broadcasting the same signal as the received broadcast signal in the shifted broadcast area. By automatically receiving the signal has the effect of providing convenience.

In addition, if it is impossible to receive a broadcast signal while receiving a broadcast signal of a predetermined broadcast station, it is provided with convenience by determining whether the communication signal transmitted from the base station is temporary or whether the broadcast area has been moved. It is effective.
