Description

  The present invention relates to a technique for changing the color of various moving images displayed on a screen of a mobile terminal, in particular, the color of a character based on a user's request, and more specifically, a Flash (registered trademark) moving image. The present invention relates to a server device, a moving image distribution system, a server program, and the like for performing arbitrary color settings for a plurality of movie clips of a SWF (Shockwave Flash) file to be configured.

  Due to the rapid development of communication technology in recent years, it has become common to display moving images such as various contents and games provided from a server via a network on a communication terminal. A typical example of such a moving image is a SWF file written by Adobe's software “FLASH”, and software (plug-in) such as a flash player for reproducing the SWF file is widely used. doing.

  In recent years, communication technology related to mobile terminals, especially mobile phones, has been remarkably developed. In addition to normal telephone communication functions, e-mail transmission / reception functions, photography functions, etc., various games and moving images can be distributed via the Internet. An increasing number of mobile phones have a function to receive.

  When receiving a game or moving image distribution via the Internet on a mobile phone, Flash Lite is mounted (plug-in) on the web browser in the mobile phone, and the moving image based on the SWF file supplied from the server is displayed on the Flash Lite. A method of reproducing is widely used.

  Here, the Flash Lite is designed for a portable terminal having a relatively small mounting capacity and working memory (RAM) capacity. Therefore, the operation is light compared to the same kind of software for a personal computer (PC). However, on the other hand, there are restrictions on the data transfer speed and restrictions on processing the Flash moving image data on the mobile terminal side.

  More specifically, for example, the version 1.1 of Flash Lite is said to correspond to the old version of Flash Player for PC (about version 4), and it is used as a model of a mobile phone used. However, for example, the file size (the maximum data size of the content file to be played back) is limited to about 100 KB, the memory size when content is executed is limited to about 1000 KB, and the screen size is greatly increased. There are inherent limitations such as being smaller (eg, 240 pixels × 240 pixels). In addition, there is a limitation that processing of Flash moving image data, for example, the color of a movie clip included in the Flash moving image cannot be changed by passing (specifying) parameters or the like.

  In the following Patent Document 1, a Flash moving image is dynamically automatically generated by a server by synthesizing character or image data sent from a portable terminal and a basic Flash operation prepared in advance by the server. Is disclosed.

JP 2007-066633

  However, Patent Document 1 does not disclose details of specific processing operations performed by the server.

  Recently, various types of moving image data have been distributed from the server to the mobile terminal. For this reason, various parameters included in the moving image data are processed on the mobile terminal side and displayed on the display unit of the own device. There is a growing need for display in various forms. In particular, if moving image data such as a game in which a characteristic character appears can be dynamically changed so that the color of the character is displayed in various forms according to the scene or action (action), Although the way to build attractive contents for mobile terminals is opened, the current moving image distribution system for mobile terminals has not yet reached this stage.

  As a measure for solving this problem, for example, all the moving image data in various forms expected to be changed are prepared in advance on the server, that is, all moving image files for each parameter on the server side. May be stored in advance as a library. However, in this case, the amount of stored data is enormous, which is not practical in terms of cost. For example, if a 60 KB file is stored in advance in the hard disk for the full color (16777215 colors), a capacity of about 1000 GB is required.

  On the other hand, recently, the version of Flash Lite has increased (2.1, 3.0, etc.), and in these cases, specifications that allow changing the parameters of moving images on the mobile terminal side have appeared, but with regard to the upgraded Flash Lite However, there is a problem that the penetration rate is still low and cannot be handled by all portable terminals, and the mounting capacity and working memory (RAM) capacity on the portable terminal side and the processing load increase.

  Embodiments of the present invention will be described in detail with reference to the drawings.

  In the moving image distribution system according to the embodiment to which the present invention is applied, a mobile terminal connected to a server via a communication network by wireless communication transmits a request, that is, request information to the server, thereby flashing one SWF action scene. Receives moving images.

  Here, as shown in FIG. 1A, the SWF action scene 1000 of one flash moving image is configured by arbitrarily connecting a plurality of SWF action files 1002 (1002A, 1002B,... 1002n). . Further, as shown in FIG. 1 (b), one SWF frame file 1001 is synthesized on the forefront of one SWF action scene 1000, thereby forming one flash moving image.

  Among these, the SWF action file 1002 is a SWF file that defines one action (action) of a character, and has a unique file name (action file name) for each file. In other words, the action file name indicates what action (action) the character specifically performs. One SWF action file can include one or more movie clips. The movie clip will be described later.

  On the other hand, the SWF frame file 1001 is a SWF file in which a frame is written, and this file also has a unique file name (frame file name) for each file.

  As shown in FIG. 2, the moving image distribution system of the present embodiment includes a game server 1 that manages game data for each user, and an image combining server that combines and transmits moving images based on user requests. 2 and the mobile terminal 3 operated by the user. Actually, an exchange or the like for performing wireless communication is interposed, but the illustration and description are omitted for the sake of brevity. In the present embodiment, the Internet is used as a communication network, but other dedicated line networks can also be used.

  In this embodiment, a configuration example of a breeding game in which characters are raised by a user's terminal operation will be described. However, the present invention is not limited to this, and can be applied to various image distribution systems.

  The game server 1 receives the operation input information of the mobile terminal 3 and, based on the received operation input information, the http request including the action specification of the character to be transmitted to the image composition server 2 via the mobile terminal 3 And a function of transmitting the generated http request to the mobile terminal 3. Specifically, as shown in FIG. 3, the game server 1 temporarily stores a game database 11 that stores data relating to the game, a game control unit 12 that performs various controls on the game, and various data. A communication control unit 14 that performs communication with the mobile terminal 3 and a control unit (CPU) 15 that controls the entire server.

  The game database 11 of the game server 1 has a user data file for recording / updating data related to the game for each user registered in advance. An example of the user data file is shown in FIG. As shown in FIG. 4, the user data file 1010 includes user information (ID, password, user name, etc.) 1011 for identifying each user, and character level information 1012 representing the current state of the character trained by the user. The operation history information 1013 representing the history of operations performed by the user so far is recorded in association with each other.

 Of these, as shown in FIG. 4, the character level information 1012 includes state information indicating the state of the current character's growth stage and the color of the current character indicated by a color parameter value (“pm” in the figure for each parameter). ) Color information represented by (). Here, the color information is set separately for each predetermined part (shape) constituting the character. In this example, the “color 1” information is the face and body color, and the “color 2” information is the color information. The color parameter indicates the color of the hand and foot. Further, as an example of the operation history information 1013, data indicating which operation is performed how many times is stored.

  With respect to the user data file 1010, the game server 1 updates the operation history information 1013 of the user every time the user performs an operation, and the number of operations performed by the user increases (for example, reaches a predetermined number of times). The character level information 1012 is set to be updated so that the level (state) of the character is sequentially increased (from an initial value of 1 to a maximum of 3). In this embodiment, when the game server 1 performs a predetermined operation (in this case, an operation of “raising ice”) among the operations performed by the user, the content of the operation (the color of ice cream described later). And a process for changing the color of the character displayed on the user terminal 3 based on the color information of the character level information 1012 and updating the color information of the character level information 1012 of the user. Yes.

  In addition, the game database 11 of the game server 1 has an action (action) performed by the character and a frame (frame, background, etc.) used by the character in response to an operation that can be performed by the user (in other words, an event name generated in the character). The operation / action definition file with the corresponding (definition). An example of the operation / action definition file is shown in FIG. As shown in FIG. 5, the operation / action definition file 1020 includes operation (event) name information 1021 that defines names of operations that can be performed by the user (in other words, events that occur in the character), and each operation (event). Action definition information 1022 that defines an action that occurs in response to this and frame definition information 1023 that defines a frame to be used in accordance with each operation (event) are registered in association with each other.

  In the example shown in FIG. 5, the action definition information 1022 of the operation / action definition file 1020 is described so that the character executes a maximum of four actions for one operation.

  Here, each frame name (frames 1, 2, 3,...) In the frame definition information 1023 is the frame file name (SWF frame file stored in the SWF frame file library 23 of the image composition server 2 described later) ( For example, “fr_0001.swf”, “fr_0002.swf”, “fr_0003.swf”,. Also, the action names (“joy”, “walk”, “laugh”, “relax”,...) Of the character in the action definition information 1022 are the SWF actions stored in the SWF action file library 22 of the image composition server 2. The file is associated with a file name (for example, “ac_0001.swf”, “ac_0002.swf”, “ac_0003.swf”, “ac_0004.swf”,...).

  Furthermore, the game server 1 stores data of the still image of the character corresponding to the character level described above, and data of an operation screen (see FIG. 8) to be described later for the user to perform various operations (such as a breeding operation) of the character. Possess.

  As shown in FIG. 6, the image composition server 2 includes a SWF file format data storage unit 21 that stores a SWF file format, a SWF action file library 22 that stores a plurality of SWF action files, and a SWF that stores SWF frame files. A frame file library 23, a transmission / reception unit 24 for transmitting / receiving data to / from a mobile terminal via a communication network, a data analysis unit 25 for analyzing data sent from the mobile terminal, and an SWF action file A parameter changing unit 26 for changing the parameters of the file in the library 22; Multiple SWF actions done Provided to the front of Airu a layer combining unit 28 to perform the process of combining the layers of SWF frame.

  Specifically, in the image composition server 2, the CPU 20 reads and executes a server program (not shown) by its own CPU 20, so that the CPU 20 performs the above-described data analysis unit 25, parameter change unit 26, and action scene connection composition unit 27. , And the layer composition unit 28. Each of these units (25 to 28) represents the main functions of the CPU 20 of the image composition server 2 extracted. Actually, the CPU 20 has various other functions for controlling the entire image composition server 2, but for the sake of brevity, the illustration thereof is omitted.

  The SWF file format data storage unit 21, the SWF action file library 22, and the SWF frame file library 23 are stored in a storage medium such as a hard disk (not shown). Various other data such as the server program are stored in the storage medium.

  The SWF file format stored in the SWF file format data storage unit 21 is data defining the specifications of the SWF file, and in this embodiment, the format of Flash Lite 1.1 is used. In other words, the version of the Flash Lite has now progressed to 3.0, but the higher version requires high specifications for the hardware of the mobile terminal, and the spread of the implementation to the mobile terminal is still the version 1. Since it has not advanced as much as one, the format of Flash Lite 1.1 is used in order to make it applicable to almost all current mobile terminals.

  The SWF action file stored in the SWF action file library 22 is an action of a character (an action such as joy, walk, run, laugh, eat, etc. illustrated in FIG. 5) in a moving image displayed on a mobile terminal. It is a file defined for each.

  Note that the SWF action files stored in the SWF action file library 22 are different from each other as long as the character state (that is, states 1 to 3 in FIG. 4) is different even if the action is the same (for example, “joy”). Become a name.

  Here, the character means an object that operates as a character among various things (objects) displayed on the screen of the mobile terminal, and includes, for example, a game character. On the other hand, objects other than characters among various things displayed on the screen of the mobile terminal are handled as “frames” stored in the SWF frame file library 23 described later.

  Usually, one character in a video consists of a plurality of objects called shapes (for example, in the case of animals, the body, legs, hands, face, eyes, mouth, etc.), and each part is They are displayed in different colors and move differently at different positions. For this reason, there is a movie clip for each part, and one SWF action file includes a plurality of movie clips, and each movie clip is synthesized as a layer.

  Note that the number of characters included in one SWF action file (that is, an object to be operated) is not particularly limited. However, for simplicity, only one character is included in one SWF action file here. The case will be described.

  The SWF frame file library 23 stores a plurality of SWF frame files, and each SWF frame file is given a unique frame file name. As described above, the SWF frame file is a SWF file in which a frame is written, in other words, a file that defines a frame (frame) of the SWF action scene.

  Here, the concept of the frame includes a stationary object, that is, a portion that does not move in the screen through a series of operations (for example, a background pattern, a wall, a decoration, etc.). In the present embodiment, one SWF frame file is added to one SWF action scene composed of a plurality of SWF action files.

  The mobile terminal 3 is a portable device capable of data communication with various terminals via a communication network, and includes various mobile phones, PDAs, and the like. Although not shown, the mobile terminal 3 includes a communication unit including a browser for performing data communication via a communication network, an operation input unit including various key buttons for a user to perform operations, various communication results, operation contents, and the like. A display unit such as an LCD for performing display and a control unit for controlling the entire apparatus are provided.

  In addition, the Adobe Flash Lite (registered trademark) is mounted on the mobile terminal 3 as software (plug-in) for playing back the moving image of the Flash file received from the server. As described above, since the image composition server 2 uses the format of Flash Lite 1.1, it can be applied if the version of Adobe Flash Lite installed in the mobile terminal 3 is 1.1 or higher.

  Next, with reference to FIG. 7, an outline of information transmission / reception performed among the game server 1, the image composition server 2, and the portable terminal 3 will be described.

  In step S1, the mobile terminal 3 is connected to the game server 1 via the communication network by the operation input unit being operated by the user. Specifically, the mobile terminal 3 accesses a predetermined breeding game providing service site provided by the business operator, so that its own communication unit is connected to the communication control unit 14 of the game server 1.

  At this time, the game server 1 can request authentication information such as a registration ID and a password from the mobile terminal 3 by accessing an authentication server (not shown) by the communication control unit 14. The authentication information received from the portable terminal 3 is temporarily stored in the memory 13. Furthermore, in the case of a paid service, the game server 1 can transmit information related to payment to the portable terminal 3 as additional information by accessing a payment server (not shown).

  In step S <b> 2 after connection, the game control unit 12 of the game server 1 reads the state information and color information (see FIG. 4) in the user character level information 1012 from the user data file 1010 of the game database 11. In step S3, the character data corresponding to the color is transmitted to the portable terminal 3 together with the operation screen data.

  FIG. 8 shows an example of an operation screen displayed on the display unit of the mobile terminal 3. In this example, when the user operates the operation input unit of the portable terminal 3 in step S4, event names ("Raise water", "Touch", "Raise ice") displayed on the screen are displayed. Etc.), an icon 1041 (1041a, b, c) is selected. Further, other various operations (for example, “move” in FIG. 5) are set to be directly operated by the key buttons of the mobile terminal 3. And the operation information which shows the event name regarding character development is transmitted to the game server 1 from the portable terminal 3 by operation of step S4 (step S5).

  When the game server 1 receives the operation information, the game server 1 temporarily stores the information in the memory 13 and stores the information in the user data file 1010 (FIG. 4) of the game database 11 and the data of the operation / action definition file 1020 (FIG. 5). Characters displayed on the user terminal 3 by collating and extracting the frame of the frame definition information 1023 corresponding to the operation (event) and the action file names 1 to 4 of the action definition information 1022 from the operation / action definition file 1020 Color parameter values of color 1 (ie, face and torso colors) and color 2 (ie, hand and foot colors) are determined, and the user operation history information 1013 and character level information 1012 (in the user data file 1010) are determined. (See FIG. 4) is updated (step S6).

  Here, the determination of the color parameter value performed by the game server 1 is performed when the received operation information is the above-described predetermined operation (that is, the operation of “raising ice”), and the color of the ice (ice cream) ( Color parameter value) is compared with the color parameter values of “color 1” and “color 2” of the character level information 1012 of the user to calculate the color change amount, and the color according to the calculated change amount Color parameter values for color 1 (face and torso colors) and color 2 (hand and foot colors) are determined so that As an example, the game server 1 determines these color parameter values so that the color 1 (face and torso color) and the color 2 (hand and foot color) are intermediate colors of the ice cream color. Can do. As another example, the game server 1 determines these color parameter values so that color 1 (face and torso color) and color 2 (hand and foot color) are as close as possible to the color of ice cream. You can also

  On the other hand, when the received operation information does not include the “raise ice” operation, the game server 1 sets the color parameter values of “color 1” and “color 2” of the character level information 1012 of the user. The color 1 (color of face and torso) and color 2 (color of hands and feet) are determined as they are.

  The game server 1 appropriately determines the character level of the user so that the color parameter values of color 1 and color 2 determined in this way become the values of “color 1” and “color 2” of the character level information 1012. Information 1012 is updated. Specifically, the values of “color 1” and “color 2” of the character level information 1012 are updated only when the received operation information is an operation of “raising ice”. Further, the game server 1 updates the operation history information 1013 (see FIG. 4) of the user according to the received operation information, and increases the character level (state) when the predetermined number of operations is reached. Thus, the character level information 1012 of the user is updated.

  Then, the game server 1 determines the color parameter values of the determined character color 1 (face and torso color) and color 2 (hand and foot color), and the extracted action file names 1 to 4. Is sent to the portable terminal 3 as request information (http request) together with the site (URL) information of the image composition server 2 (step S7).

  The mobile terminal 3 that has received the http request connects to the image composition server 2 by accessing the URL of the image composition server 2 and also receives the character color 1 (face and torso color) received from the game server 1. ) And color 2 (hand and foot colors) and information of action file names 1 to 4 are transmitted (transferred) to the image composition server 2 as input data. An example of the format of input data transferred from the portable terminal 3 to the image composition server 2 is shown in FIG.

As shown in FIG. 9, the input data 1050 includes header information 1051, frame information 1052 for designating a frame to be used, character color information 1053 for designating the color of a character to be displayed, and character information. And action information 1054 for specifying an action, for example,
nd1 | ff-fr_0001 | nc-0-008000-ff00ff | na-0-ac_00001-ac_00002-ac_00003-ac_00001
Is transferred to the image composition server 2 in a data format such as

  In the data exemplified above, “nd1” as the header information 1051 is a fixed character string indicating the type (code) of the game to be provided, and among the frame information 1052, “ff” is a fixed character string indicating the frame. "fr_0001" is the frame file name, and among the character color information 1053, "nc" is a fixed character string representing the color, "0" is the character number representing the number of characters to be displayed (here, one), and "008000" is The color parameter value of color 1 (face and torso) described above, “ff00ff” is the color parameter value of color 2 (hand and foot), and among the action information 1054, “na” is a fixed character string indicating an action, “0” Is the character number that represents the number of characters to be displayed (1), and “ac_00001”, “ac_00002”, “ac_00003”, and “ac_00001” indicate the action file names of the four actions that occur in this order, respectively. It is intended.

  If there are three or less actions corresponding to the operation (event) name (for example, when the event is “raise ice” or “move”) in FIG. 5, the game server 1 stores the action information 1054 in the action information 1054. An http request may be generated by specifying three or less action file names to be used.

  Upon receiving the information of the input data 1050 transferred from the user terminal 3, the image composition server 2 performs a process for changing the color of the target SWF file in step S8, and then selects the SWF file after the process. In step S9, the synthesized video data is transmitted to the portable terminal 3 as an http response in step S10.

  In step S11, the mobile terminal 3 that has received the moving image data reproduces and displays the moving image using the Flash Lite in its own device.

  Next, the operation of the image composition server 2 will be described with reference to FIG. 10, steps S81 to S83 correspond to the subroutine of step S8 in FIG. 7, and steps S91 and S92 correspond to the subroutine of step S9.

  In step S81, the image composition server 2 determines whether or not the input data from the mobile terminal 3 has been received. The image composition server 2 waits in step S81 until it is determined that the input data has been received. The data is temporarily stored, the process proceeds to step S82, and the SWF action file to be used is analyzed by the data analysis unit 25.

  The subroutine of step S82 is shown in steps S821 to S823 in FIG. In step S821, the data analysis unit 25 of the image composition server 2 extracts each SWF action file corresponding to the received action file name from the SWF action file library 22 and temporarily stores it. In subsequent step S822, the data analysis unit 25 refers to the SWF file format data storage unit 21 and various information described in each extracted SWF action file (for example, SWF playback time, hierarchical structure, movie clip, etc. (Shape information, etc.) is analyzed to identify a movie clip (shape) of each SWF action file. That is, as described above, a single character usually includes a plurality of parts called shapes, and each part moves differently at different positions in a moving image. For this reason, a movie clip exists for each part, and one SWF action file includes a plurality of movie clips in a hierarchical structure. Therefore, in step S822, the data analysis unit 25 grasps the hierarchical position and display position of each movie clip (shape) included in each SWF action file to be used, and the time required for playing back each SWF action file. Perform calculations.

  Here, FIG. 12 shows the relationship between a part (shape) constituting a character and a movie clip in one SWF action file.

  As shown in FIG. 12, one character is composed of a plurality of hierarchized parts, and a movie clip is assigned to each part (head, face, eyes, mouth,...). Therefore, an initial value of the displayed color is assigned to each movie clip.

  In this embodiment, among the parts constituting the character, the parts to be color-changed corresponding to the above-described color 1 and color 2 (hereinafter also referred to as “target objects”), and the color-change target. The parts that do not become are configured in advance in each SWF action file of the SWF action file 22. For example, as shown in the color classification column of FIG. 12, the face (MC — 2-1) and the body (MC — 3) of the plurality of parts constituting one character are the above “color 1”, and The hand (MC_4) and the foot (MC_5) are subject to color change as the "color 2" described above, and other parts (head (MC_1), eyes in the face (MC_2-2), mouth (MC_2-3)) Etc.) is not subject to color change. In this embodiment, it is assumed that the contents of the color classification are common to each SWF action file. However, as another embodiment, each SWF action file or each scene (SWF action scene 1000) is used as another embodiment. It can also be a separate provision.

  Therefore, the data analysis unit 25 of the image composition server 2 specifies the color parameter of the part (target object) whose color is to be changed in step S823 after analyzing the information of each movie clip in step S822.

  In step S83, the image composition server 2 causes the parameter changing unit 26 to change the corresponding SWF action so as to change the color parameter of the target object that is the target of color change in each part of the one character. Rewrite the file. Specifically, based on the analysis result of step S82, the parameter changing unit 26 selects a tag at a location where the color parameter of the target object in each SWF action file temporarily stored in step S81 is described in step S7. Are rewritten so as to have the color value designated by the input data 1050.

  In the next step S91, the image composition server 2 composes the SWF action scene by connecting the plurality of SWF action files whose color parameters have been rewritten in step S83 by the connection composition unit 27. In this embodiment, the connection synthesis unit 27 performs a process of connecting each file so that a maximum of four SWF action files are connected in time series.

  In subsequent step S92, the image composition server 2 causes the layer composition unit 28 to read the corresponding SWF frame file from the SWF frame file library 23, and the SWF action file obtained by concatenating and synthesizing the read SWF frame in step S91. The process of compositing as a layer is performed. Here, the layer composition unit 28 reads out the SWF frame (background, etc.) corresponding to the frame file name specified by the input data 1050 in step S7 and temporarily stored in step S81 from the SWF frame file library 23, and performs layer composition. Do.

  In the next step S93, the image composition server 2 outputs the data in the SWF format synthesized in step S92 to the communication network so as to be transmitted from the transmission / reception unit 24 to the portable terminal 3.

  Therefore, in the mobile terminal 3 that has received the moving image data in the SWF format, by reproducing the moving image data using its own Flash Lite, the color of a predetermined part (target object) of the character is changed to the current user's current state. The action moving image displayed and operated in the color according to the state (that is, the color parameter values of “Color 1” and “Color 2” of the character level information 1012 of the user data file 1010 (FIG. 4)) is reproduced. Further, in the portable terminal 3, by performing a predetermined operation (here, “raise ice” operation), the color parameter values of “color 1” and “color 2” of the character level information 1012 of the user data file 1010 are set. Then, the color values are changed to the color values based on the colors “color 1” and “color 2” and the ice cream color, and the action moving image in which the character is displayed and operated in the changed color is reproduced.

  Specifically, assuming that the user of the user information 0001 (see FIG. 4) operates the portable terminal 3 and performs, for example, the operation of “raising water” (see FIGS. 5 and 8), the operation is performed. For the corresponding “joy”, “drink”, “run”, and “joy” actions, the color parameter values of “color 1” and “color 2” of the character level information 1012 in the user data file 1010 (ie, pm3 and pm4) ) Is displayed in the color corresponding to. Further, at this time, the numerical value of “raise water” (see FIG. 4) of the user operation history information 1013 is updated from 1 to 2, while “color 1” and “color” of the character level information 1012 are updated. The color parameter value “2” is not updated.

  On the other hand, when the same user operates the portable terminal 3 and performs an operation of “raising ice” (see FIGS. 5 and 8), “raise ice” in the operation history information 1013 of the user. And the color parameter values of “Color 1” and “Color 2” in the character level information 1012 are changed to “Color 1” and “Color 2”. Is updated to a color (for example, pm20 and pm21) according to the amount of change between the color parameter value of the ice cream and the color parameter value of the ice cream color, and “eating (character color changes)” corresponding to the operation. For the operation, the character is displayed in a color corresponding to the color parameter values (pm20 and pm21) of “Color 1” and “Color 2” based on the updated values.

  In the above-described embodiment, the parameter changing unit 26 is configured to change the color parameter of the target object in units of scenes (SWF action scene 1000) including a plurality of actions. As another configuration example, the parameter changing unit 26 may change the color parameter of the target object in units of each action (SWF action file 1002). In this case, for example, as shown in FIG. 13, the game server 1 can use a color parameter definition file 1030 that defines the values of the character color parameters (color 1 and color 2) for each action.

  Specifically, when the color parameter definition file 1030 is used, the game server 1 further determines the color parameter in the determination process of the color parameter values of “color 1” and “color 2” in step S6 described above. The determination is also made with reference to the file 1030. That is, the game server 1 checks whether or not the color parameter values of “Color 1” and “Color 2” corresponding to the action file names (1 to 4) to be used are defined in the color parameter definition file 1030. If specified, the action is specified in the color parameter definition file 1030 (regardless of the values of “color 1” and “color 2” of the character level information 1012 in the user data file 1010). Decide to specify color parameters. The designation result can be incorporated so as to be added as additional information at the subsequent stage of the data format in FIG. 9 when the http request is generated in step S7, for example.

The format of input data using such additional information is shown in FIG. The input data 1050A shown in FIG. 14 specifies header information 1051, frame information 1052 for specifying a frame to be used, character color information 1053 for specifying the color of a displayed character, and an action to be performed by the character. It has a structure comprising action information 1054 for performing, and additional information 1055 for designating the name of the action file whose color should be individually changed and the color (color parameter value) to be changed. Here, the data format of the additional information 1055 is, for example, when “color 1” and “color 2” in the action files “ac_0002” and “ac_0003” in the example of FIG.
na_0002_nc_006000_ff11ff-na_0003_nc_007000_ff22ff
The data format can be related as follows. In addition, the additional information 1055 may have a format that specifies an action file name whose color is to be individually changed and a color to be changed.

  Assuming that the user of the user information 0001 (see FIG. 4) operates the portable terminal 3 and performs, for example, a “raise water” operation (see FIGS. 5 and 8), the color parameter definition in FIG. When the file 1030 is not used, “color 1” and “color 2” of the character level information 1012 in the user data file 1010 are used for all operations of “joy”, “drink”, “run”, and “joy”. The character is displayed in a color corresponding to the color parameter value (that is, pm3 and pm4). On the other hand, when the color parameter definition file 1030 of FIG. 13 is used, the “joy” operation among the “joy”, “drink”, “run”, and “joy” operations is “color 1”. ”And“ Color 2 ”are not stipulated in the color parameter definition file 1030, so the character has a color corresponding to the color parameter values (pm 3 and pm 4) of“ Color 1 ”and“ Color 2 ”of the character level information 1012. On the other hand, for the “drink” and “run” operations, the values of “color 1” and “color 2” are defined in the color parameter definition file 1030. ”Is pm7,“ Color 2 ”is pm8, and“ Run ”operation displays characters in colors corresponding to“ Color 1 ”pm9 and“ Color 2 ”pm10.

  In the above-described example, the case where one character is displayed in one SWF action scene 1000 has been described. However, a plurality of characters, that is, n characters (characters 1 to n) are displayed in one SWF action scene 1000. It is also possible to display them simultaneously. In this case, for example, processing is performed so that layers from the SWF action file for character 1 to the SWF action file for character n are combined at one time at the time of concatenating in step S91. In this case, by changing the color parameter described in the SWF action file so as to change to a different color for each character, the colors of the n characters displayed on the mobile terminal 3 are made various. It becomes possible.

For example, when two characters are displayed in one SWF action scene 1000, the data structure shown in FIG. 15 can be used as an example of the format of input data transferred from the mobile terminal 3 to the image composition server 2. . As can be seen from comparison with FIG. 9, the input data 1050B in this case includes the header information 1051 and the frame information 1052, the character color information 1053A for designating the color of the character 1 to be displayed, and the character 1 The structure includes action information 1054A for specifying an action to be performed, character color information 1053B for specifying the color of the character 2 to be displayed, and action information 1054B for specifying an action to be performed by the character 2. For example nd1 | ff-fr_00001 | nc-0-008000-ff00ff | na-0-ac_00001-ac_00002 | nc-1-ff0000-008080 | na-1-ac_00003-ac_00002
Is transferred to the image composition server 2 in a data format such as In the above example, the case where two characters each perform two actions has been described for the sake of brevity, but it is possible to set the input data 1050B so that each character can perform a maximum of four actions even in two-body display. It is.

  Of the above, from the header information “nd1” to the action information 1054A “na-0-ac_00001-ac_00002” of the character 1 is the same as the example of FIG. 9, and in the input data 1050B, the color information 1053B of the character 2 It can be seen that the action information 1054B is added. Here, in the character color information 1053B of character 2, “nc” is a fixed character string representing color, “1” is a character number representing the number of characters to be displayed (here, the second body), and “ff0000” is The color parameter value of color 1 (face and torso) described above, “008080” is the color parameter value of color 2 (hand and foot), and among the action information 1054B, “na” is a fixed character string indicating an action, “1” Is a character number representing the number of characters to be displayed (second body), and “ac_00003” and “ac_00002” respectively indicate the action file names of the two actions that occur in this order.

  In the above description, for the sake of simplicity, each movie clip included in one SWF action file is displayed in one frame and the color is changed in units of movie clips (shapes). It is also possible to display with a plurality of frames. When each movie clip is displayed in a plurality of frames, the color can be changed not only in movie clip (shape) units but also in frame units.

  As described above, the moving image distribution system according to the present embodiment stores items that are stored in advance in each file on the server side (character design and each action for each level). Operation) and items to be individually changed during image composition (color of the target object), and for items that require a large storage area when created and stored in multiple files in advance, the parameters (tags) of the target file Is rewritten at the time of image composition prior to distribution, so there is no need to store character files for each color on the server side in advance, and resources such as hard disks on the server side are used efficiently and economically realized. can do.

  And according to this embodiment, it is possible to perform arbitrary color settings on the server side for a plurality of movie clips included in the SWF file without disassembling the data of the SWF action file created in advance. Thus, the color parameters described in the SWF file can be dynamically changed in real time and provided to the mobile terminal.

  Moreover, since the moving image distribution system of this embodiment stores the format data of Flash Lite 1.1 as the specification of the SWF file in the SWF file format data storage unit 21, almost all of the existing ones that implement the Flash Lite. It can be applied to any mobile terminal.

  In the above-described embodiment, the so-called interactive flash system has two servers that communicate with the mobile terminal 3, but as another embodiment, an inline flash system that communicates with a single server may be used. It is. In this case, the game server 1 may be configured to have the function of the image composition server 2 (block in FIG. 6).

  Further, in the above-described embodiment, the input data input to the image composition server 1 is generated on the game server 1 side. However, as another embodiment, the input data is generated on the mobile terminal 3. In this case, the portable terminal 3 may have a function of the game server 1 (block in FIG. 3).
