Description

Field of the InventionThe present invention relates to a technique for providing an information management service to sound sources, and more particularly to a system for providing an information management service to sound sources, which provides a playlist (playlist) to the corresponding sound source by recognizing the voice of the driver.BACKGROUND OF THE INVENTIONVehicle-mounted audio systems typically include an AM / FM broadcast receiver, a compact disk player, an MPET-1 audio layer 3 (MP3) player, etc. Long time compact disk (CD) players for many consumers have been the main sound source in a vehicle. A CD having a data capacity of 75 to 80 minutes can store about 20 songs. Many CDs formatted for playing music are formatted in a waveform audio file (WAV) format. However, WAV files typically cannot provide sound source information to the CD player as well. That is, WAV files normally do not have information fields, e.g., in the case of a song, title, artist, album, year number, etc.MP3 CD players are mainly used for reproducing digital audio carriers. A MP3 format CD with a capacity of 700 M can typically store 100 songs, although the number of songs may vary depending on the size of the file of the individual songs and the sound quality. However, MP3 files may contain sound source information, referred to as ID3 tags, that provides data to the player along with the sound, other than WAV files. The MP3 file may also be stored in a mobile storage device (e.g., a USB memory, a memory card, or the like) that may be connected to the audio system to provide the MP3 file to the system upon request from the user.However, at present, in both the WAV and MP3 formats, there are no techniques or devices for automatically creating a playlist from the CD or mobile storage device on which a large number of sound sources are stored. For example, if a driver uses a conventional voice recognition system in a vehicle and inputs the name "Michael Jackson" spoken, the currently available systems could not automatically retrieve and organize a playlist from the CD and or the mobile storage device that includes only "Michael Jackson" songs.US 2008 / 0 156 173 A1 discloses a system in which a wish for music of the driver can be detected by voice command and a playlist is created on the basis of this, wherein this list can be based both on content locally present in the vehicle and on content of an Internet server with which wireless communication can be carried out.JP 2004-184 858 A further discloses a voice recognition service mediating system in which a voice recognition center for executing a voice recognition service and a plurality of local terminals having a voice recognition function are functionally connected to each other via a network, wherein the voice recognition capability of the voice recognition center with respect to a prescribed input voice is configured such that the recognition rate is high by comparing the voice recognition capability of the voice recognition center with the voice recognition capability of the local terminal, and the voice recognition center supplements the voice recognition function of the local terminal.Overview of the InventionIt is therefore an object of the present invention to provide an information management service for sound sources that manages sound source information transmitted from a driver's terminal, receives voice input data from the driver's terminal, and extracts sound source information corresponding to the voice input data input via a voice recognition system, and provides the extracted sound source information to the driver's terminal.It is another object of the present invention to provide a system for providing an information management service to sound sources by acquiring and managing sound source information corresponding to a present sound source transmitted from a driver terminal, receiving voice input data from the driver terminal, and extracting sound source information corresponding to the voice input data by a voice recognition system, and providing the extracted sound source information to the driver terminal.The objects are achieved by the subject matter of claims 1, 6, 7, 8, 13 and 15.According to an embodiment of the present invention, a driver terminal includes a sound source storage unit configured to store a sound source including sound source information, a voice input unit configured to receive the voice input data from the driver, a wireless communication unit configured to transmit the voice input data to a management server and to receive a playlist corresponding to the voice input data from the management server, a display unit configured to display the playlist transmitted to the wireless communication unit on a screen, and a control unit configured to control the voice input unit to receive the voice input data from the driver when a song selection mode has been activated by the driver to control the wireless communication unit, transmitting the voice input data to the management server via the voice input unit and controlling the display unit to display the playlist transmitted via the wireless communication unit on the screen.According to another embodiment of the present invention, a management server of a system is provided for providing an information management service to sound sources.

As illustrated in FIG. 1, a system for providing an information management service to sound sources according to an exemplary embodiment of the present invention includes at least a driver terminal 10 and a management server 20.When a voltage is applied to the driver terminal 10, the driver terminal 10 transmits sound source information corresponding to a sound source stored in a sound source storage unit 11 to the management server 20.When the sound source storage unit 11 is a CD, the driver terminal 10 may transmit the sound source information corresponding to the sound source stored on the CD to the management server 20 when the CD is inserted into the driver terminal 10. When the sound source storage unit 11 is a mobile storage device, the sound source information corresponding to the sound source stored in the mobile storage device may be transmitted to the management server 20 when the mobile storage device is connected to the driver terminal 10.The management server 20 includes the voice recognition function, manages the sound source information transmitted from the driver terminal 10, and extracts the sound source information based on the voice input data from the driver via the voice recognition when the management server 20 receives voice input data corresponding to the sound source information. The voice input data may relate to, for example, the title of a song, the name of a singger, and the like. This voice input data is received by the driver terminal 10. Based on this voice input data, the management server provides the driver terminal 10 with extracted sound source information corresponding to the driver's requested data. The transmitted sound source information is organized in a playlist. In this, the driver terminal 10 can reproduce the corresponding sound source on the basis of the playlist.For example, assume that music piece A1, music piece A2 and music piece A3 associated with children A, music piece B1, music piece B2 and music piece B3 associated with children B, and music piece C1, music piece C2 and music piece C3 associated with children C are stored in the sound source storage unit 11 in the driver terminal 10 in random order. In this case, the management server 20 receives and manages the sound source information regarding each piece of music data from the driver terminal 10, and the management server 20 manages only the sound source information and does not store sound source data. Thereafter, when the management server 20 receives the name of the singer A as voice input data from the driver terminal 10, the management server 20 creates the playlist including music pieces of the singer A, i.e., music piece A 1, music piece A 2, and music piece A 3 via the voice recognition, and transmits the created playlist to the driver terminal 10.In another example, music piece A1 and music piece A2 of the singer A and music piece B1 of the singer B are stored in a first table of the sound source storage unit 11, music piece A3 of the singer A, music piece B2 of the singer B and music piece C1 of the singer C are stored in a second table, and music piece B3 of the singer B and music piece C2 and music piece C3 of the singer C are stored in a third table thereof. In this case, the management server 20 manages the sound source information regarding music piece A1, music piece A2 and music piece B1 as the first group, the sound source information regarding music piece A3, music piece B2 and music piece C1 as the second group, and the sound source information regarding music piece B3, music piece C2 and music piece C3 as the third group.Thereafter, when the management server 20 receives the name of the singger A as voice input data from the driver terminal 10, the management server 20 provides the driver terminal 10 with a playlist consisting of music piece A 1, music piece A 2, and music piece A 3. In this case, each piece of music in the playlist is linked via sound source data in the sound source storage unit 11 so that the driver terminal 10 can reproduce pieces of music A 1, pieces of music A 2, and pieces of music A 3 sequentially or in random sequence.In another example, when the CD is inserted into and connected to the driver terminal 10, the driver terminal 10 informs the management server 20 of the sources of the sound source information and the management server 20 stores and manages the sound source information for each source.In this case, the management server 20 may include a transition unit 42 configured to cooperate with a sound source server managed based on the sound source or santger / artist membership. In this case, when the management server 20 receives part or all of the sound source from the driver terminal 10, the management server 20 may access the sound source server via the transition unit 42 and then acquire the sound source information corresponding to the present sound source. In this case, the management server 20 associates and manages the obtained sound source information IDs.In this case, a "part" of the sound source is understood to mean a sufficiently large proportion of the sound source in order to find the same sound source as the corresponding sound source by the management server 20 interacting with the sound source server.In the embodiment of the present invention, the sound source information is, for example, an ID3 tag and includes information as indicated in [Table 1] below.
