Certain embodiments of the present invention provide a method and an apparatus for providing a game playing service that simultaneously uses various reward items provided by content providers different from each other in a content providing system. The reward item may be content formed of at least one of a still image, a moving picture, music, and audio associated with purchased content. Though the present invention is described using image content (referred as a ‘sticker’ for convenience of description) representing a character, an object, or landscape, and the like associated with purchased content as an example, the same method is applicable to other types of reward items.
FIG. 1 illustrates an example content providing system according to certain embodiment of the present invention.
Referring to FIG. 1, the content providing system includes a user equipment 100, a content server 102, and a plurality of content providers (i.e., content servers) 104-1 to 104-N. Here, the user equipment 100 denotes one of various types of electronic devices that can purchase content via communication with the server, and may include a digital television (TV), a mobile communication terminal, a mobile terminal, a desktop personal computer (PC), a notebook PC, a tablet, and the like for example.
The user equipment 100 purchases content via communication with the content server 102, and receives a sticker as a reward item in reward for content purchase or use of purchased content from the content server 102 to perform a game playing function using the received sticker, that is, a sticker service function. Specifically, the user equipment 100 transmits a signal requesting (110) content which the user equipment 100 desires to purchase to the content server 102, and receives (112) the associated content and a sticker associated with the content from the content server 102. After that, the user equipment 100 executes a sticker service program that plays games using a sticker to provide a user interface that plays game using the received sticker. At this point, the sticker service program obtains in advance information regarding some or all stickers that can be obtained from the content server 102, so that it can discriminate and display the received sticker and a not received sticker on a screen. In addition, the sticker service program provides an interface that plays games using different stickers simultaneously provided by content providers that are different from each other. In addition, the sticker service program induces content purchase 114 and 116 corresponding to the not received sticker by providing content information associated with the not received sticker. In addition, the user equipment 100 transmits (118) information representing content use or purchase, that is, content history information to the content server 102, and receives (120) a reward item corresponding to the content history from the content server 102. At this point, the reward item may be a sticker, and may be various items such as other content associated with the content, a point, content purchase related coupon, and the like.
The content server 102 receives (122) content from a plurality of content providers 104-1 to 104-N, generates a sticker associated with respective provided content, and maps the sticker to the content to store the same. Of course, the sticker may be received from respective content providers 104-1 to 104-N. When specific content are requested (110, 114) by the user equipment 100, the content server 102 retrieves the relevant content and a sticker associated with the relevant content to provide (112, 116) the same to the user equipment 100. In addition, when receiving (118) content history information from the user equipment 100, the content server 102 retrieves one or more reward items corresponding to the content history to provide (120) the reward items to the user equipment 100. In addition, as content provided by the content providers 104-1 to 104-N and related stickers change, the content server 102 updates the sticker service program to provide the same to the user equipment 100. For example, when new content are provided by the plurality of content providers 104-1 to 104-N, the content server 102 generates a sticker associated with the provided content, and then adds information associated with new content and a new sticker to the sticker service program to provide the updated sticker service program to the user equipment 100. As described above, the content server 102 provides a sticker associated with the purchased content to the user equipment 100, and provides the sticker service program that allows a user to play games simultaneously using all stickers provided by the content providers 104-1 to 104-N, thereby inducing the user equipment 100 to purchase various content to provide a promoting effect for the content providers 104-1 to 104-N.

In addition, the storage 320 may store a sticker service program, and store a table representing reward items corresponding to a content purchase history or a content use history. At this point, the reward item may be a sticker, and may be various items such as other content associated with the content, a point, a content purchase related coupon, and the like.
The method described above in relation with FIG. 3 under of the present invention may be provided as one or more instructions in one or more software modules stored in the respective server.
FIGS. 4A and 4B illustrate example signal flows for providing a reward item corresponding to content purchase in a content providing system according to certain embodiments of the present invention.
Referring to FIGS. 4A and 4B, each of a plurality of content providers 404-1 to 404-N registers content in a content server 402 in step 410. The content server 402 generates a sticker for respective registered content and maps the stickers to the content to store the same in step 412. Here, the sticker may be received from a relevant content provider.
When a content server access event occurs under user control in step 414, user equipment 400 proceeds to step 416 to transmit a signal requesting a content list to the content server 402. The content server 402 transmits the content list representing stored content to the user equipment 400 in step 418. At this point, the content server 402 may transmit corresponding sticker information for respective content included in the content list together.
The user equipment 400 determines content to purchase among the content included in the content list under the user control in step 420, and proceeds to step 422 to transmit a signal requesting the determined content to the content server 402. At this point, the content server 402 retrieves the content requested by the user equipment 400 and a sticker associated with the requested content in step 424, and proceeds to step 426 to transmit the retrieved content and sticker to the user equipment 400.
The user equipment 400 that has received the content and the sticker stores the received content and sticker and determines information associated with received sticker to register the information associated with sticker in a possess sticker list representing a possess sticker state of the user equipment in step 428.
When the sticker service is executed under the user control in step 430, the user equipment 400 proceeds to step 432 to discriminate a possessed sticker and a not possessed sticker to display a sticker list representing stickers that can be obtained from the content server 402. For example, the possessed sticker may be displayed by directly displaying an original image or highlighting the image. The not possessed sticker may be displayed by changing color of an original image dimly or processing an outline region using a dotted line.
When a not possessed sticker is selected by the user in step 434, the user equipment 400 proceeds to step 436 to display content information corresponding to the selected not possessed sticker. That is, in case of purchasing certain content, the user equipment 400 displays information as to whether the possessed sticker can be obtained. In addition, the user equipment 400 may display a message window requesting determination as to whether to purchase relevant content.
The user equipment 400 determines to purchase content associated with the selected not possessed sticker under user control in step 434, and transmits a signal requesting the determined content to the content server 402 in step 440. At this point, the content server 402 retrieves content requested by the user equipment 400 and a sticker associated with the requested content in step 442, and proceeds to step 444 to transmit the retrieved content and sticker to the user equipment 400.
The user equipment 400 stores the received content and sticker, and determines information associated with received sticker to register the information associated with sticker in a possess sticker list representing a possess sticker state of the user equipment in step 446.
The user equipment 400 transmits the possess sticker state information to the content server 402 in step 448. The content server 402 determines a reward item depending on the sticker possess state of the user equipment 400 in step 450, and proceeds to step 452 to provide the determined reward item. At this point, the user equipment 400 may transmit a content purchase history or a content use history to the content server 402 instead of the sticker possess state, and receive a reward thereto.
FIGS. 5A and 5B illustrate example processes for operating user equipment according to certain embodiments of the present invention.
Referring to FIGS. 5A and 5B, the user equipment determines whether an event for accessing a content server occurs under user control in step 501. When the event for accessing the content server does not occur under the user control, the user equipment immediately proceeds to step 513.
In contrast, when the event for accessing the content server occurs under the user control, the user equipment proceeds to step 503 to request the content server to transmit a content list and receive the same, and display the received content list on a screen.
The user equipment determines whether specific content are purchased under the user control in step 505. When the purchase of the specific content is not determined, the user equipment proceeds to step 533 to determine whether a content server access ends. When the content server access ends, the user equipment immediately proceeds to step 513. When the content server access does not end, the user equipment returns to step 505.
In contrast, when the purchase of the specific content is determined, the user equipment proceeds to step 507 to request that the content server transmit the purchase-determined content, and receive the requested content and a sticker associated with the requested content from the content server in step 509. At this point, the user equipment may receive an ID of the sticker. After that, the user equipment determines information associated with the received sticker to register the information associated with the sticker in a possess sticker list representing a possess sticker state of the user equipment in step 511. At this point, the user equipment may provide information as to the sticker has been obtained via purchase of which content afterward by storing information regarding content received together with the sticker.
After that, the user equipment determines whether a sticker service is executed in step 513. When the sticker service is not executed, the user equipment ends the algorithm.
When the sticker service is executed, the user equipment displays a sticker list discriminating and displaying a possessed sticker and a not possessed sticker in step 515. For example, as illustrated in FIG. 7A, possessed stickers 701 may be directly displayed as their original images, and not possessed stickers 703 may be displayed by displaying them dimly using dotted lines. Here, the sticker list may include all stickers that can be obtained from the content server and may include only stickers of a specific category that can be obtained from the content server. Of course, in the case where the sticker list includes only the stickers of the specific category, the user equipment should receive an ID of a relevant sticker and category information when receiving the sticker from the content server, and should classify and manage received stickers for each category. Here, each of the stickers illustrated in FIG. 7A may be a sticker associated with content provided by content providers different from each other.
After that, the user equipment determines whether a reward obtain event corresponding to content purchase and a sticker possess state occurs in step 517. Here, the reward obtain event may occur when a predetermined reward obtain condition is met or under user control. For example, the reward obtain event may occur when the user equipment possesses a predetermined number of stickers, or when the user equipment possesses all stickers of a specific category, and may occur depending on the user's reward item obtain menu selection.
When the reward obtain event corresponding to the content purchase and the sticker possess state occurs, the user equipment transmits a content purchase history and a sticker possess state information to the content server in step 535, and receives a reward item from the content server in step 537. At this point, when the content purchase and the sticker possess state of the user equipment do not meet a reward condition of the content server, the user equipment may receive a signal representing that the reward condition is not met from the content server. After that, the user equipment proceeds to step 541 to determine whether the sticker service ends. When the sticker service does not end, the user equipment returns to step 519. When the sticker service ends, the user equipment ends the algorithm according to the present invention.
Meanwhile, when the reward obtain event corresponding to the content purchase and the sticker possess state does not occur, the user equipment proceeds to step 519 to determine whether a possessed sticker is selected from the sticker list displayed on the screen.
When the possessed sticker is not selected, the user equipment proceeds to step 521 to determine whether a not possessed sticker is selected. When the not possessed sticker is not selected, the user equipment proceeds to step 541 to perform subsequent steps.
In contrast, when the not possessed sticker is selected, the user equipment displays content information associated with the selected not possessed sticker in step 523. Here, the user equipment may display content information associated with the not possessed sticker by obtaining in advance information regarding all stickers possessed by the content server and stickers associated with respective content from the content server. For example, as illustrated in FIG. 8A, in the case where the user selects a specific not possessed sticker 801 displayed dimly, the user equipment may obtain the selected not possessed sticker when purchasing a series 8 of content A. At this point, the user equipment may display that other stickers may be additionally obtained besides the selected not possessed sticker.
After that, the user equipment determines whether purchase of the displayed content is determined under user control in step 525. When the purchase of the displayed content is not determined, the user equipment returns to step 519 to re-perform subsequent steps. When the purchase of the displayed content is determined, the user equipment proceeds to step 527 to request the content server to provide the purchase-determined content. After that, the user equipment may receive the content and the not possessed sticker associated with the content from the content server in step 529. The user equipment determines information associated with received sticker to register the information associated with sticker in a possess sticker list representing a possess sticker state of the user equipment in step 531 and proceeds to step 541.
In contrast, when the possess sticker is selected, the user equipment proceeds to step 539 to provide a game playing function that uses a sticker possessed by the user equipment. For example, as illustrated in FIG. 7A, the user equipment may arrange possessed stickers 701 on a desired position of the screen under user control, and change the background screen. At this point, though not shown, the user equipment may control the size, rotation angle, color, and the like of the possessed sticker under the user control. In addition, as illustrated in FIG. 7B, the user equipment may input text on the screen under user control to provide a game where character stickers make a conversation. At this point, the user equipment may convert a voice signal inputted from the user into text to provide a conversation game as illustrated in FIG. 7B, and may convert a voice signal or a text character inputted from the user into a voice signal of a designated voice to provide an effect as if a character of a specific sticker talked. Additionally, the user equipment may provide a game function of configuring a plurality of scenes using the possessed stickers and making one story book using the plurality of scenes. In addition, the user equipment may provide a function of applying a dynamic effect to each sticker to produce a moving picture.
Of course, when a possessed sticker is selected in step 519, the user equipment may display content information associated with the possessed sticker. For example, as illustrated in FIG. 8B, in the case where the user selects a specific possessed sticker 811 displayed clearly, the user equipment may purchase a series 2 of content A to represent that the selected possessed sticker 811 has been obtained. At this point, the user equipment may display other stickers obtained by purchasing the series 2 of the content A together.
FIG. 6 illustrates an example process for operating a content server according to certain embodiments of the present invention. Here, description is made on the assumption that the content server receives content from a plurality of content providers and stores a sticker for respective content.
Referring to FIG. 6, the content server determines whether a signal requesting a content list is received from user equipment in step 601. When the signal requesting the content list is not received, the content server immediately proceeds to step 605. When the signal requesting the content list is received, the content server transmits the content list representing content stored in the content server to the user equipment in step 603.
The content server determines whether a signal requesting specific content is received from the user equipment in step 605. When the signal requesting the specific content is not received, the content server immediately proceeds to step 611. In contrast, when the signal requesting the specific content is received, the content server proceeds to step 607 to determine a sticker associated with the requested content. After that, the content server transmits the requested content and the determined sticker to the user equipment in step 609.
After that, the content server determines whether information representing content purchase or a content use history and a sticker possess state is received from the user equipment in step 611. When the information is received, the content server determines a reward item to be provided to the user equipment using a predetermined reward item table for each content purchase or each consumption history or a predetermined reward item table for each sticker possess state in step 613. At this point, the reward item may be a sticker, and may be various items such as other content associated with the content, a point, a content purchase related coupon, and the like After that, the content server provides the determined reward item to the user equipment in step 615, and returns to step 601 to re-perform subsequent steps. Here, in the case where the content purchase or consumption history and a sticker possess state of the user equipment do not meet a predetermined condition and so a relevant reward item cannot be determined in the table, the content server may transmit a signal representing that the content purchase or consumption history and the sticker possess state of the user equipment has not met the predetermined reward condition. At this point, when the user equipment purchases specific content or a predetermined number of content additionally, the content server may inform the user equipment that the reward condition is met and induce additional purchase of content.
Methods according to various embodiments described in claims and/or specification of the present invention may be implemented in hardware, software, or a combination of the hardware and the software.
In the case of implementing the method using software, a computer-readable storage medium storing one or more programs (software module) may be provided. One or more programs stored in the computer-readable storage medium are configured for execution by one or more processors inside an electronic device.
