BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a music playback device, and more particularly, to an Internet broadcast-based music playback device that searches Internet broadcasts that reproduce music files of a predetermined music genre according to a speed and automatically reproduces the music files.

As is known, an internet radio is a radio broadcast provided through the Internet, and is transmitted through an Internet protocol. Therefore, it is possible to listen to music through various devices such as smart phone, MP3 player, PDA, and computer.

Unlike conventional airwave radio stations, Internet radio is relatively simple to install and operate, and a number of personal Internet radio stations are operating in accordance with the improvement of the Internet network performance. In other words, the Internet radio broadcasting field is attracting attention because individuals can broadcast on a small scale.

However, current Internet radio is dominated by operators of Internet radio stations, although listeners' opinions are respected, and listeners are only listening to music delivered from Internet radio stations.

As described above, due to the development of wired / wireless networks, devices capable of receiving Internet radio broadcasting signals regardless of time and place are widely spread.

Therefore, it is necessary to use a device different from the current Internet radio broadcasting method. In other words, by allowing the owner of the device to take advantage of the Internet radio broadcast, it is possible to use a service other than the existing Internet radio broadcast.

Of course, fundamentally, Internet radio is very much in operation, and the listener can choose the internet broadcasting he wants. In this case, however, the user (listener) has to select one of a large number of Internet radio broadcasts.

In addition, most of the selected Internet radio broadcasts only broadcast specific music files. In this case, the listener only listens to music files belonging to a specific genre. In other words, due to the nature of Internet radio broadcasting, only some music files of a specific music genre are broadcasted to a certain audience.

The present invention basically searches for a broadcast signal for reproducing a music file belonging to a specific music genre according to a speed among a plurality of Internet radio broadcast signals and plays the music file.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, preferred embodiments of an Internet broadcast-based music reproducing device according to the present invention will be described in detail with reference to the accompanying drawings.

The present invention relates to an apparatus and method for searching for and reproducing an Internet broadcast signal broadcasting a predetermined music genre in correspondence with a moving speed when the user himself or herself is moving, a moving speed when moving on a bicycle, a vehicle, To a music playback device. In addition, the music reproducing device can be applied not only to a smart phone, an MP3 player, a PDA, but also to audio, car AVN (audio, video, navigation)

Hereinafter, for convenience of explanation, a case where a user moves on a vehicle will be described. However, it should be understood that the present invention is not limited thereto, but can also be applied to a case where a user carries a device, such as a walk, jogging, or a bicycle.

1 is a block diagram illustrating an Internet broadcast-based music playback device according to a preferred embodiment of the present invention.

A search unit 110 for searching a plurality of internet radio broadcast signals (hereinafter, referred to as 'broadcast signals') is configured in the Internet broadcast-based music reproducing device 100 (hereinafter referred to as 'device'). As described above, since the Internet radio may be directly operated by an individual, it is difficult to confirm the number of Internet radio broadcasts currently operated. So it is not easy for the user to check this one by one. The search unit 110 can search all the broadcast signals that the device 100 can receive at present or automatically according to a separate operation. Of course, the search range and search method can be set. For example, it searches for broadcast signals within a few kilometers in radius on the basis of itself, or stops the search process when the number of broadcast signals to be searched is all detected. Or may search only broadcast signals for broadcasting music files belonging to different music genres in conjunction with an analyzing unit described later.

The analysis unit 120 analyzes the genre of the music file included in the searched broadcast signal. There are many ways to analyze music genres. For example, it extracts a specific part of the music file being played and analyzes the music genre through the extracted part. Or the speed or melody of the music file, the instrument information used, and the like. Alternatively, it is possible to analyze the genre by sampling the signal of the music file, extracting the characteristic value, and analyzing it as a characteristic of the musical instrument signal according to the characteristic function.

And a sensor unit 130 for detecting speed information is configured. The sensor unit 130 functions to accurately detect the moving speed of the user, the moving speed of the bicycle or the vehicle. Examples of the sensor unit 130 include a sensor using a Doppler effect such as an ultrasonic wave, a laser or a microwave, an acceleration sensor, a device such as a movable coil or a movable iron core sensor in which a magnet or an iron core is inserted in a coil, A vehicle speed sensor through information such as a speed sensor and a wheel, and a sensor utilizing navigation information of a GPS or a vehicle. These sensor elements can be constituted by one or two or more sensors.

And a control unit 140 for receiving and reproducing a broadcast signal belonging to a music genre corresponding to the detected speed information.

The speed information and music genre information are as follows. If the first to fifth speeds are classified as '0 to 30 km', '30 to 60 km', '60 to 90 km', '90 to 120 km', and '120 km or more' ',' Jazz ',' dance ',' rock 'and so on. This can be summarized as shown in Table 1 below.

speed Music genre The first speed (0 to 30 km) classic The second speed (30 to 60 km) Ballade Third speed (60 ~ 90km) jazz Fourth speed (90 ~ 120km) dance Fifth speed (over 120km) Rock

Of course, this is only one example, and it will be appreciated that speed information and range, music genre information, and the like can be changed differently.

The setting unit 150 is configured to set the number of times or time so that the music genre is not frequently changed according to frequent speed changes. That is, when searching for broadcast signals of different music genres every time the speed is changed, it is difficult to normally listen to music, and battery consumption may be increased due to operations for searching broadcast signals and analyzing genres of music files. Because the device uses a rechargeable battery power when it is portable, it is important to prolong usage time so that it can be used for a long time. Therefore, even if the speed is changed frequently, such as 59km -> 62km -> 58km -> 61km, if the number of times of change is within a predetermined range or within a predetermined time, the music file currently being reproduced is continuously reproduced.

Next, an operation of the Internet broadcast-based music reproducing device will be described. 2 is a flowchart illustrating a process of selecting a broadcast signal and playing music according to the device of the present invention.

The vehicle travels from the state in which the passenger (driver) on the vehicle carries the device or uses the telematics to associate with the vehicle audio (s100). Of course, the device is powered on.

The search unit 110 of the power-on device 100 searches the broadcast signal in real time (s102). The retrieved broadcast signal may be at least one or more.

The analysis unit 120 analyzes the music signal included in the broadcast signal searched by the search unit 110 (s104). You can check the music genre of the music file according to the music signal analysis. The music genre is either 'classic', 'ballad', 'jazz', 'dance', or 'rock'.

As described above, while the searching unit 110 and the analyzing unit 120 perform the corresponding functions, the sensor unit 130 continuously detects the current speed of the vehicle (s106).

The detection result of the sensor unit 130, that is, the current speed information of the vehicle, is transmitted to the control unit 140. Then, the control unit 140 selects a broadcasting signal for broadcasting a music file having a music genre matching the current speed information based on the current speed information of the vehicle (s108). Then, a music file broadcast in the broadcasting signal is reproduced (S110). For example, if the current vehicle speed is in the range of 90 to 120 km, the broadcasting signal for broadcasting the music file of the dance genre is selected.

Therefore, even if the user does not search for the Internet broadcast signal, the user can simply listen to the music while the vehicle is running. At this time, the music being played is changed according to the vehicle speed.

Thereafter, in step s112 of determining whether the vehicle speed is changed, the speed detection and the process of selecting a broadcasting signal corresponding thereto are repeatedly performed when the vehicle speed is changed. However, if the vehicle speed is not changed, the current broadcast signal is continuously received (s114).

On the other hand, more than one broadcast signal for broadcasting a music file belonging to the same genre among the broadcast signals analyzed by the analysis unit 120 can be analyzed. In this case, the search unit 110 can receive and reproduce the music file of the broadcast signal searched first. Or in conjunction with navigation, a music file close to the arrival time may be received and reproduced on the basis of the destination arrival time.

Of course, a broadcast signal broadcasting a music genre corresponding to the vehicle speed may not be retrieved or analyzed. In this case, it is possible to reproduce music by selecting a broadcast signal for broadcasting a music file of the music genre closest to the vehicle speed. For example, while the vehicle speed is 80 km, the music of the jazz genre should be reproduced, but there may be no broadcast signal for broadcasting the music of the jazz genre. At this time, a broadcast signal for broadcasting dance music, which is a music genre of the fourth speed close to 80 km, is selected and reproduced.

As described above, according to the present embodiment, the user selects a broadcast signal for broadcasting music of a specific music genre according to the moving speed of a user (vehicle) among Internet radio broadcast signals, and reproduces the selected broadcast signal.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, It will be apparent that modifications, variations and equivalents of other embodiments are possible. Therefore, the true scope of the present invention should be determined by the technical idea of the appended claims.
