1. Field of the Invention
Apparatuses and methods consistent with the present invention relate to providing multimedia content and, more particularly, to an apparatus and method for providing multimedia content, which, through a mood code corresponding to a quantity ratio of the type of content input by a user, abstracts similar mood-content registered by a user or lists of the content, and provides it to the user.
2. Description of the Related Art
The development of data compression and network technologies has enabled users to receive multimedia content such as music files over the Internet.
A multimedia content providing system may include a multimedia content providing device and a user terminal. When this is the case, the multimedia content providing device provides multimedia content corresponding to a keyword received by the user terminal or multimedia content recommended by reference to other information.
A multimedia content providing device 11 may have various types of multimedia content; particularly, the multimedia content providing device 11, providing music files, may have music files 15 classified by groups such as title, artist, lyric, release date, and number of downloads.
When a user inputs a keyword to the user terminal 12, the multimedia content providing device 11 receives the input keyword, and then searches for music files corresponding to the keyword. The multimedia content providing device 11 transmits the abstracted music files based on a search result or a list of the music files to the user terminal 12.
Accordingly, a user can receive his/her favorite music files via the user terminal 12.
Also, a user may directly search for music files by connecting to database of the multimedia content providing device 11 via the user terminal.
A multimedia content providing device 21 may recommend music files 25 by checking how many times a user has accessed each music file based on the keyword and search message received by the user terminal 22, and checking the renewed multimedia content.
The recommended music files 25 include recommended songs, new songs, and new albums. After connecting to the multimedia content providing device 21 via the user terminal 22, a user may select and receive one or more of the recommended music files 25.
The multimedia content providing device 21 may provide multimedia contents to a user through a search method or a recommendation method.
However, the multimedia content provided by a search may be provided only when a user has information on his/her favorite music files. If a user does not have information on his/her favorite music files, the multimedia content providing device 11 cannot provide music files.
The multimedia content provided using the recommendation method have a drawback in that the same music files are provided to all users regardless of preference. Accordingly, a user may not receive desired music files when using the recommendation type method.
Korean Unexamined Patent 2003-0059503 discloses a custom service method, which stores information on features of music files in database by abstracting features of various music files prepared for an online music service, searches for music files having a feature information value that is very similar to a feature information value of a user's favorite music, which is generated by collecting and analyzing information on features of music files desired by user, and provides the found music files.
However, the Korean Unexamined Patent 2003-0059503 relates to providing a music file corresponding to a feature information value given by a user, which is the same as the method of classifying music files by groups such as title, artist, lyrics, release date, and number of downloads.

The mood code is an album including content at a specific quantity ratio by type or identifying information given to a registering user. Mood codes of albums registered by different registering users may be the same if their type and ratio are the same as each other even though the quantity of content included in each album is different.
Hereinafter, audio content will be described, but this is merely exemplary. Still image content, moving picture content, and other types of content may be included without departing from the spirit and scope of the invention
The number of types may be different and varied according to how the content providing device 300 is embodied, and may be set by a registering user.
The storage unit 320 may store the content included in the content list. A user who wants to use the contents by searching for an album (hereinafter, referred to as a searching user) may access corresponding content via the retrieved content list.
The storage unit 320 may be built in the apparatus as a module able to input/output information, such as a hard disk, a flash memory, a compact flash (CF) card, a secure digital (SD) card, a smart media (SM) card, a multimedia card (MMC), or memory stick, or may be included in an additional device.
The analyzing unit 330 analyzes a quantity ratio by the type of content input by a searching user. A terminal of the searching user may transmit a content list to the content providing device 300 by searching for content stored in the terminal, and may transmit the content list to the content providing device 300 by directly receiving it from the searching user.
A searching user may also store a content list in the storage unit 320 by registering his/her favorite content list as a registering user in advance. The analyzing unit 330 may analyze a quantity ratio by type of content by using the stored searching user's content list.
The type in this exemplary embodiment includes at least one of genre, age group, time, feeling, weather, situation, title, artist, and lyrics. The analyzing unit 330 may analyze a ratio based on several types of content included in a single content list.
For example, the analyzing unit 330 may analyze a quantity ratio of content by age group as well as a quantity ratio of content by genre. Therefore, it is possible to analyze the details of the content.
The analyzing unit 330 may analyze, by type, the quantity ratio of content included in a registering user's content list stored in the storage unit 320. When a content list is registered by a registering user, the analyzing unit 330 may analyze the registering user's content list. When a searching user searches for content, the analyzing unit 330 may analyze the registering user's content list.
The mood code generating unit 340 generates a mood code corresponding to the ratio calculated according to analyzed result of the analyzing unit 330.
As described above, the analyzing unit 330 may analyze a quantity ratio of one or more types of content; whereby, the mood code generating unit 340 may generate each mood code corresponding to a quantity ratio of one type of content and, additionally, several types of content, and then may generate a single mood code integrating each mood code.
The mood code generating unit 340 generates a mood code as a result of the analyzing unit 330; whereby, the mood code generating unit 340 generates a mood code for a registering user's content list as well as a searching user's content list. The storage unit 320 stores the registering user's ID or album based on the generated mood code. The corresponding content list may be stored in the storage unit 320 by logically connecting to the registering user's ID or album.
The mood code will be described in detail with reference to
The content abstracting unit 360 abstracts a content list corresponding to the generated mood code from the storage unit 320. The storage unit 320 stores a registering user's ID or album based on the mood code. The content abstracting unit 360, after searching for a registering user's mood code that is similar to a searching user's mood code received from the mood code generating unit 340, abstracts a registering user's content list stored based on the retrieved mood code, or after searching for a registering user's album mood code similar to a searching user's mood code, abstracts a content list included in the stored album based on the retrieved mood code.
After calculating the similarity between a searching user's mood code and a registering user's mood code, or between the registering user's album mood codes, the content abstracting unit 360 may abstract the corresponding content list only when the similarity is in a critical range or threshold determined by a searching user.
The sending/receiving unit 310 sends at least one of a content list abstracted by the content abstracting unit 360 and the contents included in the content list to the searching user's terminal.
The sending/receiving unit 310 receives a content list required to be registered from a registering user, receives a content list required to be registered from a searching user, and sends a web service or web services to a user having a similar mood code.
A communication method used between the sending/receiving unit 310 and a registering user's terminal or between searching user's terminals may be a wired communication method such as Ethernet, universal serial bus (USB), IEEE 1394, serial communication, and parallel communication, or a wireless communication method such as infrared communication, Bluetooth, home radio frequency (RF), and wireless local area network (LAN).
The group service generating unit 350 creates a group that consists of similar mood codes, of mood codes generated by the mood code generating unit 340, and generates a web service or web services for the group.
The web services may include online chatting and multimedia content sharing. That is, a searching user may chat with a registering user having an album of a mood code similar to the searching user's album or mood code, or exchanges content with the registering user. However, the web services generated may include other types of web services without departing from the spirit and scope of the present invention.
The sending/receiving unit 310 sends the generated web service to searching and registering users having mood codes included in the group. The searching and registering users may receive the web service via the content providing device 300 and point to point devices (P2P), or the like.
As described above, the analyzing unit 330 may analyze a quantity ratio by type of input content. Here, the content refers to content input by searching and registering users.
The analyzing unit 330 analyzes a quantity ratio of content based on a type or types set in advance. The ratios 420A, 420B, and 420C may be different according to the set type. For example, if a series of content lists 410 exist, a quantity ratio of content having genre classified as blues, jazz, classical and popular songs may be 30%, 20%, 10%, and 40%. A quantity ratio of the same content classified by age groups consisting of 10's, 20's, 30's, and 40's may be 20%, 40%, 30%, and 10%.
That is, the ratios and mood codes 430A, 430B, and 430C may be different according to the types of content set. The analyzing unit 330 may analyze a quantity ratio of various types of content 420A, 420B, and 420C as well as a quantity ratio one type of content.
The analyzed result is transmitted to the mood code generating unit 340. The mood code generating unit 340 generates mood code corresponding to the transmitted ratio. That is, the mood code generating unit 340 generates mood codes 430A, 430B, and 430C.
The mood code generating unit 340 integrates the generated mood codes 430A, 430B, and 430C as a single mood code 440 that will be a mood code for a registering user or a registering user's album.
The searching or registering users may select the type, which is analyzed by the analyzing unit 330. The registering user may set a type while registering his/her favorite content list 410. The analyzing unit 330 analyzes the ratios 420A, 420B, and 420C set by a searching user. The mood code generating unit 340 generates the integrating mood code 440 according to the analyzed result.
The type set by a searching user and the type set by a registering user may be different. A mood code generated according to the type set by the user for a content list registered by a registering user may be compared with a searching user's mood code. It is possible to compare a mood code corresponding to types set by the searching user and a mood code corresponding to types set by registering user.
The format of the mood codes 430A, 430B, and 430C, and the format of the integrated mood code 440 may be different according to how the mood code generating unit 340 is embodied; the formats may be identical or different.
For example, the format of the mood codes 430A, 430 B, and 430C may be English letters A to Z. If the format of the mood codes 430A, 430 B, and 430C, and the format of the integrated mood code 440 are different, where mood codes 430A, 430 B, and 430C based on four types: B, A, H, and Q,; the integrated mood code may be represented by BAHQ.
If the format of the mood codes 430A, 430 B, and 430C, and the format of the integrated mood code 440 are identical, where 430A, 430 B, and 430C are types B, A, H, and Q, the mood code generating unit may generate the integrated mood code as D, i.e., a single mood code 440 integrating the mood codes B, A, H, and Q.
Since the type, which is analyzed by the analyzing unit 330, may be applied differently by a user, and the number of types may also be applied differently, the format of 430A, 430 B, and 430C, and the format of the integrated mood code 440 may be identical. In this respect, mood codes may be compared with no regard to types or the number of types.
The storage unit 320 of the content providing device 300 may store a registering user's ID according to a mood code. That is, after forming a single group that consists of several registering users having a similar mood code, the storage unit 320 stores each registering user's ID based on mood codes 510A, 520A, and 530A.
The content abstracting unit 360 abstracts a registering user's content list stored based on a mood code, which is similar to a searching user's mood code, of mood codes stored in the storage unit 320
The group service generating unit 350 generates a group service for users having a similar mood code. The group service may be transmitted to a searching user having a similar mood code.
The storage unit 320 of the content providing device 300 may store a registering user's album according to a mood code. That is, after forming a single group that consists of registering user's albums having a similar mood code, the storage unit 320 stores albums based on the mood codes 510B, 520B, and 530B.
The content abstracting unit 360 abstracts a content list included in registering user's albums stored in the mood codes 510B, 520B, and 530B, which is similar to a searching user's mood code of mood codes stored in the storage unit 320.
The searching user, who receives the content list included in the mood codes 510B, 520B, and 530B, may receive a group service generated for users having the corresponding mood code.
The group service generating unit 350 of the content providing device 360 generates web services 610, 620, and 630 having a similar mood code. The generated web services 610, 620, and 630 are transmitted to a terminal 600 of a user logged in via the sending/receiving unit 310.
The web services 610, 620, and 630, in this case, include online chatting and content sharing, but they may also include other web services. Users having a similar mood code may chat with each other online, and may share content or a content list. Here, the content sharing refers to not only a direct exchange of content but also an exchange of streaming. That is, a specific user, included in a group, may perform a streaming service using his/her content to other users.
Since web services 610, 620, and 630 are a group service provided to users having a similar mood code, if a user's mood code is changed by modifying his/her content list, the group of web services provided to the user may be also changed.
In the case where the content abstracting unit 360 of the content providing device 300 generates web services 610, 620, and 630 for an album group having a similar mood code, the generated web services 610, 620, and 630 are transmitted to a user having the corresponding album.
Since the mood code generated corresponding to an album depends on only the corresponding album (hereinafter, referred to as a first album), a change of a content list included in the user's other album (hereinafter, referred to as a second album) may not effect a change of the mood code corresponding to a first album.
That is, a user may receive a web service which is changed based on a second album by changing the content list included in the second album, and continue to receive the same web service corresponding to the first album.
To provide multimedia content to a searching user, the sending/receiving unit 310 of the content providing device 300 receives a content list from a registering user (S710).
The received registering user's content list is transmitted to the analyzing unit 330. The analyzing unit 330 analyzes the content list to determine a quantity ratio by type of content in the content list (S715). Here, for purposes of illustration, the type includes at least one of genre, age group, time, mood, weather, situation, title, artist, and lyrics.
Also, the analyzing unit 330 may analyze the content list to determine a quantity ratio based on several types of content included in a single content list. For example, the analyzing unit 330 may determine a quantity ratio by age group of content, as well as a quantity ratio by genre of content.
The result of the analyzing unit 330 is transmitted to the mood code generating unit 340. The mood code generating unit 340 generates a mood code as a result of the quantity ratio or ratios determined by the analyzing unit 330 (S720). And, the mood code generating unit 340 stores a content list corresponding to the generated mood code in the storage unit 320; at this time, a registering user's ID or album is stored according to the mood code (S725). Since only the stored album's title may be stored, the content list included in the album may be additionally stored by logically connecting to the registering user's ID or album.
After storing a registering user's content list, the sending/receiving unit 310 receives a content list from a searching user (S730).
The received searching user's content list is transmitted to the analyzing unit 330. The analyzing unit 330 analyzes the content list to determine a quantity ratio of content types in the content list (S735).
The searching user's content list may be received via the sending/receiving unit 310, or it may be a content list that was registered in advance. If a searching user's content list was registered in advance, the analyzing unit 330 may analyze it by searching the storage unit 320 according to the searching user's login and abstracting a content list corresponding to a searching user's ID.
The analyzing unit 330 may analyze the content list to determine a ratio based on several types of contents included in a single content list; since this was described above, and explanation thereof will be omitted.
The result of the analyzing unit 330 is transmitted to the mood code generating unit 340. The mood code generating unit 340 generates a mood code corresponding to the received result (S740).
The generated mood code is transmitted to the content abstracting unit 360. The content abstracting unit 360 abstracts a registering user's ID or album corresponding to the mood code received by searching for the storage unit 320, and abstracts a content list corresponding to the registering user's ID or album (S745).
The abstracted content list is transmitted to a searching user's terminal via the sending/receiving unit 310 (S750).
The group service generating unit 350 generates a web service corresponding to the mood code as a mood code of registering or searching users is generated S755. The web service may include online chatting and multimedia content sharing. The generated web service may be transmitted to a user having the corresponding mood code via the sending/receiving unit 310 (S760).
In this regard, a registering or searching user who receives a web service may chat online, or may exchange multimedia content with another user.
As described above, the apparatus and method for providing multimedia content according to the various exemplary embodiments of present invention may produce one or more effects described below.
According to the present invention, the apparatus and method may abstract content or a content list of a similar mood code registered by a registering user by using a mood code corresponding to a quantity ratio of content input by a searching user, thereby providing desired content to a searching user.
According to another exemplary embodiment of the present invention, the apparatus and method enables management of an additional group that consists of users who have a similar mood code, thereby providing a service according to a user's preference.
