3 is a schematic flowchart for explaining a broadcast music providing method according to an embodiment of the present invention. 4 is a schematic view for explaining a method of providing broadcast music according to an embodiment of the present invention. Hereinafter, a broadcast providing apparatus 200, a broadcast information DB 300, a music information DB 400, an image DB 500, a matching information DB 600, The music service providing apparatus 700, and the user terminal 800. [ However, in the present invention, for example, the image DB 500 or the matching information DB 600 is included in the broadcast music providing apparatus 100, or the music service providing apparatus 700 includes the broadcast music providing apparatus 100 Or may be implemented to be configured together. Hereinafter, for convenience of explanation, the configurations of the broadcast music providing apparatus 100 of FIG. 2 will also be described.

Referring to FIG. 3, a real-time broadcast including audio and video is received from the broadcast providing apparatus 200 (S300). The real-time broadcast received from the broadcast providing apparatus 200 may be separately received for each channel. An example of real-time broadcasting is a drama program. In the drama program, the background music for directing can flow through a specific screen after actors' acting. In addition, different music can be inserted in the middle of each situation. Hereinafter, it is assumed that the background music inserted in the drama program is provided during the first time 414 of 2017.11.18, 20:08:00, 2017.11.18, 20:08:48.

Next, audio is extracted from the received real-time broadcast (S310), and the actual broadcast time of the extracted audio is obtained (S320). Referring to FIG. 4A, a real-time broadcast is represented by successive video and audio tracks. The broadcast music providing apparatus 100 can temporarily store the audio separated from the video. The broadcast music providing apparatus 100 may divide the separated audio into segments of a predetermined time and use it for music detection. Hereinafter, it is assumed that an audio segment of 20 seconds is used for music detection. Referring to the audio track, for example, no background music was detected in the segments until 20:07:55. Segment 412 from 20:07:55 to 20:08:15, which is next detected, is used for the next music detection.

Next, if the extracted audio is music, the music name and artist of the music are detected based on the extracted audio (S330). Referring to Fig. 4 (b), it is detected that the music is included in the segment 412, and the music is detected for the song name AAAA and the artist XXXX. The manner of music recognition is not limited and is not limited as long as it is configured to distinguish song names and artists. The music information DB 400 may be used for music recognition.

Next, a part or still image corresponding to the broadcast time of the audio extracted from the real-time broadcast image is extracted (S340). The segment 412 may be defined as audio extracted as it is, and the video or still image corresponding to the segment 412 may be determined as a part or still image of the video corresponding to the broadcast time.

In various embodiments, the segment 412 is a segment of a predetermined period of time for the detection of music, so once the music is determined in step S330, the audio may be analyzed again to determine the broadcast time at which the actual music was provided. Referring again to FIG. 4 (b), since it has been detected that the provision of music is started at 20:08:00 in the segment 412, the audio after that is analyzed and it is detected that the music ends at 20:08:48 . Accordingly, the time 414 from 20:08:00 to 20:08:48 when the music is actually provided can be determined as the broadcast time of the music. When the broadcast time 414 of the actual music is determined, a part 416 or still image of the image corresponding to the broadcast time of the actual music can be extracted. Referring to Figures 4 (a) and 4 (c), an image clip 416 during actual music presentation is shown, and in particular with reference to Figure 4 (c), a still image 418). Since the beginning of the music can be perceived deeply by the user, the still image 418 can be selected at the beginning of the music when still images are used.

A portion 416 of the acquired image or a still image 418 may be stored separately in the image DB 500, for example. In various embodiments, images or still images may be stored in the matching information DB 600 or in the storage unit 120 of the broadcast music providing apparatus 100. [

Next, the broadcast time of the audio, a part of the image or the still image, the name of the music, and the artist are stored and provided (S350). Referring to FIG. 4 (d), the broadcast time of the stored audio, part of the image or still image, song name, and artist may be stored in the matching information DB 600, for example. The above information may be stored and managed in the matching information DB 600. A video or still image having a relatively large capacity may be separately stored in the image DB 500 and only the location information thereof may be stored.

In various embodiments, text describing the image may additionally be stored. The image description text may be used as an element for describing the corresponding image and for matching when the user searches for the corresponding image. The text may include a hashtag. The collection method of the text describing the image is not limited. For example, the collection of text may include metabolites collected from comments on the image or recognized from audio. In order to implement such a text gathering method, a step of collecting a comment on a video or a step of performing voice recognition on the audio may be added. The stored matching information may be provided at the request of the music service providing apparatus 700 or directly to the user terminal 800. [

According to the method for providing broadcast music according to an embodiment of the present invention, a part of music used in broadcast can be searched even if only a naturally recognized broadcast screen is displayed. In addition, it is possible to view only the portion of the background music inserted in the program, thereby providing a highlight function for the broadcast.

5 and 6 are schematic diagrams illustrating a user interface visually provided to a user terminal in a broadcast music providing method according to an exemplary embodiment of the present invention.

Referring to FIG. 5, a method of visually providing broadcast music to a user terminal through a timeline interface is shown. The program title 811 is displayed on the display unit 810 of the user terminal 800 and the start time 812 and the end time 813 at which the recognized music is provided along the time line for the broadcast program having the time axis Respectively. A still image or thumbnail 814 of the broadcasted video during that time is provided adjacent to the timeline and information of the music that has been played during the video broadcast is provided together. The information of the music may include the music title 815 and the artist 816 as shown in FIG. 5, but this is an example and various information can be displayed.

Also, in various embodiments, when a still image or thumbnail 814 is selected 817, a portion of the extracted image or audio may be provided to the user terminal. For example, in FIG. 5, when still image 814 is selected 817, an image is reproduced in the area of still image 814 and a corresponding portion of broadcasted music may be provided.

The program title 811, the number of times, and the like can be determined using EPG (Electronic Program Guide) information. The received EPG information and the real-time broadcast can be matched and utilized. 6, a list of music titles and artists of music detected in one of the programs in real time broadcasting is stored, and a list of music titles 815 and artists 816 are provided under the program title 811 . In Fig. 6, a specific song is selected from the list and shows an interface representing information about the song. A song "This Heart is A Stone" is selected, and a broadcast screen on which the song was provided as information on the song is visually provided together with the time (812) and the still image (814) at which the song was played back.

Through the user interface using information from the broadcast music providing method of the present invention shown in FIGS. 5 and 6, the user can quickly and accurately recognize the music recognized in the broadcast, and can use the streaming service or download the music.

FIG. 7 is a schematic flowchart illustrating a method of performing a search using data on images in a broadcast music providing method according to an embodiment of the present invention. Referring to FIG.

A method for easily searching for music embedded in broadcasts collected through a broadcast music providing method according to an embodiment of the present invention is also required for a user. It may be easy to find the inserted music immediately after the broadcast, but it is very difficult to find the music that is memorized dimly from the long time ago. To facilitate this particular search, a search may be performed in various ways.

For example, referring to FIG. 7, an image or a still image for a search may be received from a user (S700). Next, the video or still image for searching can be matched to the video of the stored real-time broadcasting. The manner of matching an image to an image is not limited, and a known image search method may be used. When a similar image or still image is searched in the matching information DB, the real-time broadcasting time and channel of the image or still image are determined (S710). If there is music reproduced in the corresponding real-time broadcast time and channel, the determined real-time broadcast time and the song name and artist of the music reproduced in the channel can be provided {S720}. The method using this image can increase the probability of finding the music desired by the actual user.

On the other hand, if the user does not have an image for searching, the user can search for the music provided in the corresponding image by searching for the corresponding image. As described with reference to FIG. 3, a part of the image or a description text of the still image may be stored together with the matching information. Thereafter, a query including a description of the image can be received from the user. Next, it is determined whether the query and the explanatory text are matched. If the query and the explanatory text are matched, a part or still image corresponding to the explanatory text, a song name and an artist of the music may be provided.
