Description

TECHNICAL FIELD [0001] The present invention relates to a method of providing automatic channel selection service for a radio broadcast using a big data analysis,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for providing an automatic channel selection service for a radio broadcast using a big data analysis capable of automatically switching a radio broadcast channel having the best broadcast quality considering radio broadcast quality according to the location of a user terminal.

Recently, FM broadcasting uses Very High Frequency (VHF), and in order to prevent radio wave interference between 87.5 ~ 108MHz, it is divided by 100kHz and allocated to each broadcasting station by region.

FM broadcasting is a frequency modulation method which has a lot of channels, less noise, less interference, and sound quality, and is suitable for stereo music broadcasting. However, the FM broadcasting has a strong straight-line characteristic, and if there are obstacles due to terrain conditions such as buildings and mountains, the receiving sensitivity is significantly deteriorated, and the reaching distance of the radio wave is short and the structure of the transceiver is complicated. This FM broadcasting is widely used because the cost of the receiver is lowered, the program production cost is lowered, the additional cost is not generated due to the easy accessibility and the free service.

Korea began broadcasting FM stereo radio in 1970 and started FM radio broadcasting service in Busan KBS 2nd radio in 1981. As of March 2017, 21 radio broadcasters operate 178 FM radio stations, reinforcing radio transmission stations in areas with low FM reception sensitivity. Considering the characteristics of the FM radio broadcasting frequency, radio broadcasting is allocated to the whole country by allocating the broadcasting area, and there are cases where the same frequency is reused in other broadcasting areas, which may cause interference and confusion of high output broadcasting frequencies in some areas.

With the development of communication technology, digital radio FM broadcasting service started in the 1990s, and radio broadcasting is converting from analog radio broadcasting to digital radio broadcasting. Digital radio broadcasting is divided into the European DAB (Digital Audio Broadcast) method and the US IBOC (iBiquity's in-band on-channel) method. Some countries in Europe are stopping analog radio broadcasting and promoting digitization. For example, in the UK, digital FM radio coverage has been activated by more than 90%, while some European countries have stopped analog radio broadcasting.

 The DAB method increases the frequency efficiency by transmitting the audio stream on one broadcast frequency through multiplexing and compression techniques. The IBOC method is a compression algorithm applied to existing analog audio channels, and converts audio and data of AM radio broadcasting and FM radio broadcasting to digital signals and transmits them. Accordingly, the IBOC method can simultaneously transmit a plurality of broadcast programs to an analog signal of one broadcast channel. This IBOC method was the only approved method in 2002 by the Federal Communications Commission (FCC) to transmit digital audio broadcasting in the United States. According to 2009 statistics, more than 1,700 (84%) of the US broadcasters broadcast on IBOC technology, and more than 100 broadcast on multicast channels.

In giving the United States TagStation provides a cloud-based data service that enables you to synchronize images, interactive content and other data to be displayed in the broadcast of radio NextRadio apps, HD Radio ^® and car dashboards. NextRadio combines the built-in FM tuner and the Internet to provide users with a high-quality radio broadcasting service. Developed as an app for smartphones, it provides album contents and program information along with music, . Here, users can be notified of disaster alarms or add streaming services to provide paid services for music sources.

However, Korea still broadcasts radio in analog form and proceeds to discuss digitalization of radio broadcasting, and aims to digitize radio broadcasting in 2013. However, despite the many advantages of digital broadcasting, noise, digital modulation , Audio compression method, etc., and the prospect of digitization of radio broadcasts is unclear due to the sluggish support due to weakened broadcasting business. However, the digitization of the production process has already been completed, such as converting the analog signal to digital in the process of broadcasting program production.

Therefore, in the present analog radio broadcasting conditions, it is necessary to provide the listeners with the maximum service of program and music information. To this end, various devices have been developed for automatic radio station selection during vehicle movement in an analog broadcast environment. Some technologies have been applied to vehicles by developing technologies that use GPS devices, devices that measure frequency spectrum intensity, or radio broadcast station data on the vehicle radio dashboard to tune to the radio station frequencies of those locations.

Listening to radio broadcasts using mobile phones has enabled mobile phone manufacturers to listen to analog radio broadcasts on some mobile phones by developing modules that can listen to radio broadcasts. One of the disaster warning systems that will promptly report disasters after the 2016 Kyungju earthquake, FM radio broadcasts are used as a disaster broadcasting tool, enabling users to listen to disaster alarms through radio broadcasts on their mobile phones. Accordingly, a variety of measures and means are required for user convenience and demand for listening to radio broadcasts using mobile phones and providing various services.

In this way, there are many users who listen to AM / FM radio on the move by using a cellular phone or a radio receiver in the vehicle. However, when passing the boundary of the broadcasting area, if the broadcasting frequency is out of the terrestrial interference or the audible area, The radio broadcasting is interrupted due to the phenomenon of being interfered by the propagation of other broadcasting stations in the vicinity, or a situation occurs in which noises are generated and can not be listened to.

In this case, it becomes impossible to listen to the broadcasts suddenly, and it is troublesome to make the listeners confused, to reset the local broadcast channel, or to re-search the channel to select the preferred broadcast.

Particularly, a driver of a vehicle is required to operate the radio receiver in order to obstruct the safe driving of the radio receiver, and may seriously affect the safety of the driver and his / her passenger. In addition, The probability of occurrence is increased. In this way, when an accident occurs due to an operation for the radio station selection by the driver of the vehicle, it causes human and material loss.

On the other hand, when using a mobile phone while driving, it is a major cause of dispersion of attention, and there is a report that the incidence of traffic accidents increases by four times due to the dispersion of attention. In 2018, we are raising premiums for drivers who use mobile phones while driving, and efforts are being made to add advanced devices (eg, Head Up Display) to help the driver look ahead.

As the mobile communication is activated and the life pattern is changed, the listening rate of radio broadcast using the radio receiver is reduced, so that a music source is purchased from a public place listening to a radio using a radio receiver at a fixed place and stored in a mobile phone, Music streaming service is spreading.

According to the Survey Report on the Use of Broadcasting Media (2017 Broadcasting Media Usage Behavior Survey, Korea Communications Commission, Dec. 12, 2017) surveyed by the Korea Communications Commission, the media ownership rate of households was 96% for TV sets and 96.4% Cell phones are becoming a personal essential medium. In contrast, personal media holdings such as MP3 players have dropped to 2.3%, but smartphones are steadily increasing at 78.8% in 2015, 83.3% in 2016, and 87.1% in 2017. It can be seen that the media centered on TV and radio have been spreading the influence of smartphone by being divided into TV and cable TV at home and Internet and mobile communication by individuals.

Looking at the degree to which smartphones are recognized as an essential medium in everyday life, TVs have been reversed since 2015, and the perception of essential media is changing in 2017, with 38.1% for TV and 56.4% for smartphones. This is related to the fact that the number of smartphones has reached 87.1% in 2017 and almost every person has one smartphone. The ratio of smart phone holdings in metropolitan cities and small and medium cities is 58.1% and 60.2%, respectively, which is considered to be a more essential medium than in small cities, indicating that smartphones are recognized as major media media compared to other media.

In the usage frequency survey, 81.4% of smartphones use the media more than five days a week, which is overwhelmingly higher than 77.2% of TVs, while PC / notebooks and newspapers are decreasing. The rate of video on demand (VOD) usage of younger generations with a smartphone ownership rate of 96% is 16.5% in 2017, up 4.2% from the previous year. VOD and OTT (online video service) usage rate of smartphone holders are 13.1% for VOD and 20.3% for OTT, and they are watching video using smartphone / tablet PC.

The main listener of radio broadcasting was 30 ~ 50, and the rate of listening was 76.8% in the morning and 20.8% in the home. Listening to the radio was 81% in car radio and 6.8% in real time smartphone. Radio users use an average of 1 hour and 33 minutes per day, compared to an average of 56 minutes per day.

Recently, households in their 20s ~ 30s are increasing, and their life patterns are expected to change, and they tend to use smartphones as main media for radio and TV viewing in real life. The usage rate of smartphone by one person is very high, which is more than 90% in 10 ~ 40s. OTT use rate is 71.1%, and it depends on paid service.

In the "Seminar on Enlargement and Activation of the Listening Population for Future Radio Future" hosted by the Korean Broadcasting Societies (May 9, 2017), radio broadcasting is experiencing difficulty in radio broadcasting due to the emergence of new media such as streaming radio and podcasts. The service of loyal listeners with economic efficiency, simplicity and intimacy, and became the opportunity to receive publicity attention as a disaster broadcasting medium. It is necessary to activate the radio which is beneficial to the data cost, traffic, accessibility and disaster response ability of the smartphone.

Because of the portable communication means in which the mobile function has dramatically developed, popular music listeners are widely used to listen to music in a streaming broadcast or purchase a sound source directly from a sound source service provider and download it to a mobile phone and reproduce it. When playing a sound source using a streaming method, a user can listen to the music while on the move, but the cost of the sound source and the data communication cost is increased.

In radio broadcasting with high publicness, it is advantageous to listen to radio broadcasting without burdening the cost of sound source and data communication, but there is a disadvantage in that information is not easily provided and convenient because of one-way analog communication. In the digital mobile era, analog radio broadcasting is in the stage of being converted into digital radio broadcasting, but measures should be taken to reduce media communication costs while enhancing convenience and efficiency of radio listeners using mobile phones.

However, due to the linearity of FM radio waves and the limitation of the output, the intensity of the radio wave at the receiving point changes depending on the distance from the transmitting station and the terrain condition, and in particular, Noise can be selected and disconnected. This results in the inconvenience of radio listeners and the deterioration of radio broadcast preferences.

Most of the radio listeners listen to the radio on the moving vehicle and rediscover the broadcast program to eliminate radio noise or noise while driving. When operating the auxiliary devices of the vehicle panel while driving the vehicle, the concentration and attention of the driver are dispersed to weaken the ability to cope with the crisis, and the probability of a vehicle accident increases. In order to prevent accidents caused by carelessness, it is recommended that the use of smart phones and the operation of vehicle panels be kept safe during operation.

To solve this, a technique has been developed for a method for automatically tuning a radio channel while the vehicle is moving. The first method is to automatically switch the radio channel on the move based on the broadcast area data, and the second method is to automatically switch the radio channel by measuring the reception intensity of the radio wave.

The first method is to set the jurisdiction of the local broadcasting station and to apply the broadcasting frequency and the output in order to increase the utility and utilization of the broadcasting channel in the country adopting the analog transmission method. The same broadcast frequency may be used. If the user knows exactly the position of his or her movement point, the broadcast frequency can be easily reset by selecting the desired radio broadcast at the movement point with reference to the broadcast region database.

Although the first method is advantageous in that it is simple and relatively low in cost for automatic channel selection of a radio broadcast channel, the broadcast frequency band is clearly defined, but the broadcast frequency receiving region and the reception sensitivity are not clearly distinguished, Noise, and crosstalk can not be considered at all. Also, there is a problem that the first method may cause inconvenience to the user due to automatic tuning of the radio broadcasting without consideration of the frequency reception strength at the boundary of the broadcasting region.

While mobile phones have been provided with radio broadcasting listening functions, many applications for mobile phones using broadcasting area information have been developed, but the streaming broadcasting has spread and radio listening rate has not been activated.

The second method is to select an optimal broadcast channel by measuring the field strength of the FM radio broadcast frequency transmitted in an analog manner at a receiving point. A method for measuring the electric field intensity of a radio wave is to analyze the strength of a received frequency using a GPS receiver and a field strength measuring device for measuring a position on a radio receiver at a moving point, It is possible to automatically tune in accordance with the receiving strength by using the actually measured electric field intensity at the moving point.

However, since the second method requires addition of an electric field strength measuring device and an optimal frequency selection algorithm, a cost burden is incurred as compared with the first method. In addition, the second method requires a process of measuring and analyzing the frequency field intensity at the moving point continuously during the movement, giving excessive load to the radio receiver and, in response to a small change in the frequency spectrum intensity at the moving point, There is a problem that it may cause confusion. First of all, there is a problem that the second method causes great confusion due to interference due to radio frequencies and crosstalk transmitted from the adjacent transmitting stations at the terrain or area boundary.
