[Embodiment 1]
Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the drawings. The embodiment described below is an example of a content server that can distribute data related to a managed content as an example of a content providing device according to the content providing system, and an example of a content reproduction device according to the content providing system. An example in which the present invention is applied to a client terminal that can receive and reproduce data related to content from a content server will be described. However, the present invention can be applied to any device capable of distributing data related to content or receiving and reproducing the data.

  In the content providing system according to the present embodiment, the content provided by the content server 100 will be described as what is called online game content performed via a network. In the client terminal 200, a basic program related to game execution is executed as an application, and the user starts connection to the content server 100 by executing the application, and the game content service provided by the content server 100 Can be used. When the client terminal 200 receives data related to the game content from the content server 100, the client terminal 200 can display a screen generated using the data on a display unit 208 (described later) of the client terminal 200. Alternatively, the received audio data can be reproduced. However, the content provided by the content server 100 is not limited to game content, and can be applied to any content in which the client terminal 200 executes content playback processing using data related to the content received from the content server 100. It is.

<Configuration of content provision system>
FIG. 1A is a diagram showing a system configuration of a content providing system according to an embodiment of the present invention.

  As shown in the figure, in the content providing system of this embodiment, the content server 100 and the client terminal 200 are connected via a network 300 that is a public line such as the Internet. In the present embodiment, since the content provided by the content server 100 is an online game content, the content server 100 and the client terminal 200 are described as being connected via the network 300, but both devices are directly connected. It will be easily understood that it may be a thing. Needless to say, the content server 100 and the client terminal 200 may be connected via another relay device.

<Functional Configuration of Content Server 100>
Next, the functional configuration of the content server 100 of the present embodiment will be described in detail using the block diagram of FIG. 2A.

  The server CPU 101 controls the operation of each block included in the content server 100. Specifically, the server CPU 101 controls the operation of each block by reading out the operation program for each block stored in the server ROM 102 and developing it in the server RAM 103 for execution.

  The server ROM 102 is a rewritable nonvolatile memory, for example. The server ROM 102 stores not only the operation program for each block of the content server 100 but also parameters and the like necessary for the operation of each block. The server ROM 102 manages user accounts, passwords, and the like of content services provided by the content server 100.

  The server RAM 103 is a volatile memory. The server RAM 103 is used not only as a development area for the operation program of each block of the content server 100 but also as a storage area for storing intermediate data output in the operation of each block.

  When there is a content provision request from the client terminal 200, the data selection unit 104 determines data to be transmitted to the client terminal 200 and transmits the data via the server communication unit 106 described later. Data relating to game content provided by the content server 100 in this embodiment is recorded in the server recording medium 105. The server recording medium 105 may be a recording device connected to the content server 100 such as an HDD. Assume that each piece of data relating to game content recorded on the server recording medium 105 is associated with classification information predetermined for each data. The classification information is not limited to the type of data, such as model data, texture data, or collision determination data, and may be information that can be used for classification.

  The server communication unit 106 is a communication interface included in the content server 100 that performs communication with an external device using a predetermined communication protocol. The server communication unit 106 is a so-called communication protocol stack, such as a connection unit (physical layer in the OSI reference model) between the content server 100 and an external communication line or antenna, PPP, HDLC, IPv4, IPX, TCP, UDP, or the like. Communication protocol (an arbitrary communication protocol such as a link layer, a network layer, a transport layer in the OSI reference model). The server communication unit 106 may not include the transport layer and the network layer in some cases.

<Functional configuration of client terminal 200>
Next, the functional configuration of the client terminal 200 of the present embodiment will be described in detail using the block diagram of FIG. 2B.

  The CPU 201 controls the operation of each block included in the client terminal 200. Specifically, the CPU 201 controls the operation of each block by reading out the operation program of each block stored in the ROM 202, developing it in the RAM 203 and executing it.

  The ROM 202 is a rewritable nonvolatile memory, for example. The ROM 202 stores parameters and the like necessary for the operation of each block in addition to the operation program for each block of the client terminal 200.

  In the present embodiment, the ROM 202 stores information (required data information) that specifies data required at least when drawing processing (reproduction processing) starts to be performed for content provided by the content server 100. Is done. The necessary data information includes basic data necessary for a minimum drawn object on the game content screen, such as model data for the main character. However, the data included in the necessary data information is not limited to this, and can be selected so that a screen related to the content is provided under conditions desired by the user.

  The RAM 203 is a volatile memory. The RAM 203 is used not only as a development area for the operation program of each block included in the client terminal 200 but also as a storage area for storing intermediate data output in the operation of each block.

  The request data determination unit 204 determines data necessary for drawing the screen related to the content in the client terminal 200 for the game content provided by the content server 100. Specifically, the request data determining unit 204 refers to the necessary data information and makes a request for transmitting the necessary data to the content server 100 according to the reception status of the data related to the content. Note that the transmission request generated by the request data determination unit 204 is transmitted to the content server 100 via the communication unit 205.

  The communication unit 205 is a communication interface of the client terminal 200 that performs communication with an external device using the same communication protocol as the server communication unit 106, for example.

  The GPU 207 generates a screen related to game content provided by the content server 100. Specifically, the GPU 207 draws a screen to be displayed on the display unit 208 (described later) in a connected VRAM (not shown) using data related to the content received from the content server 100 under the control of the CPU 201.

  The data holding unit 206 is a recording device that stores data related to content received from the content server 100. When drawing the screen by the GPU 207, the data held in the data holding unit 206 is read out, developed in a GPU memory (not shown), appropriately processed, and drawn in the VRAM.

  The display unit 208 is a display device included in the client terminal 200 such as an LCD. The display unit 208 may be an integrated display device provided in the client terminal 200, or may be an external display device connected to the client terminal 200.

  The operation input unit 209 is a user interface included in the client terminal 200 such as an operation button, a keyboard, or a touch panel. When an operation input by the user is made, the operation input unit 209 analyzes the input and transmits a control signal corresponding to the operation content to the CPU 201.

<Data reception operation>
First, a data receiving operation in the content providing system of this embodiment will be described.

  In the content providing system according to the present embodiment, data (first data) that is at least necessary for starting the content provision to the user at the client terminal 200 as data related to the game content, and data (first data) that is not necessary for the provision start. 2 data) and received at different timings. Specifically, the client terminal 200 starts receiving the second data after receiving the first data. That is, unlike the conventional method in which processing for providing content to a user is executed after all data related to the content is received, in the content providing system of the present embodiment, the client terminal 200 has the first data After intensive reception, execution of processing for providing content can be started. As described above, the game content can be provided to the user without receiving all the data, so that the waiting time of the user related to the content provision can be reduced.

  In the content providing system of the present embodiment, whether the data related to the game content is the first data or the second data is determined based on the necessary data information described above. In the present embodiment, the request data determination unit 204 refers to the necessary data information when making a transmission request for data related to the game content, and when there is first data that has not yet been received, transmission of the corresponding data is performed. Although described as a request, the method of receiving two types of data separately is not limited to this.

  For example, the data transmission request may be made with one transmission request for one scene. In this case, the necessary data information only needs to be transmitted to the content server 100 together with the data transmission request. In the content server 100, the server CPU 101 refers to the received necessary data information and first concentrates the first data on the client terminal. 200 may be transmitted.

  For example, the necessary data information may be stored in the content server 100 in association with a user account that uses the content. In this case, the user may generate necessary data information unique to the user in the setting phase using the client terminal 200 and store it in the content server 100. When the server CPU 101 receives a data transmission request from the client terminal 200, the server CPU 101 first refers to the necessary data information associated with the user account that is logged into the service using the client terminal 200. It is only necessary to start transmission of one data.

  In the present embodiment, the necessary data information is described as being settable according to user preferences, such as emphasis on shortening standby time and emphasizing graphic quality, but is not limited thereto. For example, the first data or the second data may be defined according to the type of classification information described above. Further, for example, the setting may be changed by the server CPU 101 or the CPU 201 according to the data transfer rate between the content server 100 and the client terminal 200. That is, in an environment where a sufficient data transfer rate cannot be ensured, the waiting time is prolonged, so the necessary data information may be changed so as to automatically reduce the data size related to the first data.

<Data classification example>
Here, a classification example of the first data and the second data according to the game content is shown below. It should be noted that the following is for illustrative purposes, and it is easily imagined that the present invention is not limited to this.

-2D graphics In the case of 2D graphic games such as so-called fighting games and action games, the graphic data of the main character used by the game user and the collision information set for the character are given priority as the first data. Sent to. On the other hand, data that does not necessarily need to be displayed or used at the start of content provision, such as background graphic data or GUI data such as time display, is transmitted as second data after transmission of the first data is completed.

-3D graphics In the case of a 3D graphic game in which a character moves in a 3D scene, model data (or vertices and vertices, etc.) of a main character in an occurring event such as a user operation character or a user operation character during cooperative play Vertex connection data), terrain data of the drawing range, model data of the terrain object, collision information near the main character and main character, binary space division (BSP) information, and the like are transmitted preferentially as the first data. On the other hand, model data other than the main character may be transmitted as the second data.

  The classification in the 3D graphic game is not limited to this. In particular, when a depth range to be drawn is set, model data of characters and objects belonging to the range may be the first data. When binary space division (BSP) information is used, model data of a character or object drawn in front according to the information may be classified as first data.

  If color information is set in the model data itself (each vertex information), the texture data applied to the model data may be classified as second data. The texture data applied as a distant view of the field may be classified as the first data.

  In addition, GUI data that is displayed in 2D on a 3D scene may be classified as second data in the same manner as in a 2D graphic game.

Thinking routine Information such as a thinking routine related to AI in a so-called board game needs to be consistent data in the game, and is necessary information from the beginning of the game, and therefore is classified as first data. Is preferred. Note that, for example, a thinking routine that defines an action pattern such as an NPC character in a 3D graphic game has a low necessity for consistency in the game, so only a part of the data is classified as the first data, and other data May be classified as second data.

-Movie data Movie data reproduced in game content is preferably classified as second data because of its large data size. However, the classification may be changed in coding units (GOP). For example, a predetermined number of GOPs from the beginning may be classified as the first data.

-Audio data The audio data reproduced in the game content may be classified according to its use. For example, sound data such as sound effects that require a response to a user operation may be classified as first data, and sound data that does not require a response such as BGM may be classified as second data.

  As described above, the classification of the data related to the game content received by the client terminal 200 is exemplified for each data attribute. However, in addition to this, the classification may be defined as follows by paying attention to the data size.

  For example, for still image data such as moving image data and texture data, data with a reduced encoding rate and resolution given priority to data size reduction is provided as first data, and encoding suitable as second data is provided. Data of rate and resolution may be provided. At this time, the second data may be data that replaces the first data. It may be difference information with respect to the first data such as an H.264 / SVC extension layer.

  This can also be considered for voice data and model data. That is, for audio data, data with a reduced sampling rate or encoding rate is classified as first data, and audio data with a suitable sampling rate or encoding rate is provided later as second data. Also good. The model data may also be a form in which simple model data is provided as first data and detailed model data is provided as second data later.

<< Data acquisition process >>
A specific process of the data acquisition process for acquiring data related to the game content executed in the client terminal 200 of the present embodiment having the above-described configuration will be described with reference to the flowchart of FIG. The processing corresponding to the flowchart can be realized by the CPU 201 reading, for example, a corresponding processing program stored in the ROM 202, developing it in the RAM 203, and executing it. Note that the data acquisition process will be described as being started when, for example, a scene switching event occurs in game content and it is necessary to receive new data from the content server 100.

  In step S <b> 301, the CPU 201 causes the request data determination unit 204 to determine data (request data) that needs to be acquired from the content server 100. Specifically, the CPU 201 transmits information indicating data used for drawing the next scene specified in the game process for controlling the execution of the game to the request data determination unit 204. The request data determination unit 204 refers to information indicating data used for drawing the next scene, and determines data that is not held in the data holding unit 206 as request data.

  In step S <b> 302, the request data determination unit 204 transmits a first data provision request to the content server 100 via the communication unit 205 under the control of the CPU 201. Specifically, the request data determination unit 204 refers to necessary data information stored in the ROM 202, and generates a provision request for data classified as first data among the request data determined in S301. Then, the request data determination unit 204 transmits the provision request to the communication unit 205 for transmission.

  In step S <b> 303, the CPU 201 determines whether the communication unit 205 has received data from the content server 100. If the CPU 201 determines that the data has been received by the communication unit 205, the process proceeds to S304. If the CPU 201 determines that data has not been received, the process proceeds to S305.

  In step S <b> 304, the CPU 201 stores the received data in the data holding unit 206. At this time, the CPU 201 updates management information for managing data stored in the data holding unit 206, for example, stored in the RAM 203.

  In step S <b> 305, the CPU 201 determines whether or not reception of at least first data necessary for drawing processing of the next scene has been completed. Specifically, the CPU 201 determines whether or not the request data determination unit 204 has notified that all the first data has been received. The request data determination unit 204 monitors the management information, and performs notification when all of the first data requested to be provided is stored in the data holding unit 206. When the reception of the first data is completed, the CPU 201 starts execution of the drawing process in the game process, and moves the process to S306. If the first data has not been received, the CPU 201 returns the process to step S303.

  In step S <b> 306, the request data determination unit 204 transmits a second data provision request to the content server 100 via the communication unit 205 under the control of the CPU 201.

  In step S <b> 307, the CPU 201 determines whether the communication unit 205 has received data from the content server 100. If the CPU 201 determines that the data has been received by the communication unit 205, the process proceeds to S308. If the CPU 201 determines that data has not been received, the process proceeds to S309.

  In step S <b> 308, the CPU 201 stores the received data in the data holding unit 206. At this time, the CPU 201 updates management information for managing data stored in the data holding unit 206, for example, stored in the RAM 203. At this time, since the received data is the second data, the CPU 201 executes the drawing process including the data in the drawing process of the already started game process. More specifically, the CPU 201 uses the first data and the received second data in the drawing process for the frame to be drawn next.

  In step S309, the CPU 201 determines whether reception of all data used for drawing the next scene is completed. Specifically, the CPU 201 determines whether or not the request data determination unit 204 has notified that all of the first and second data have been received. The request data determination unit 204 monitors the management information, and performs notification when all of the second data requested for provision is stored in the data holding unit 206. If the CPU 201 determines that the reception of all data used for drawing the next scene has been completed, the CPU 201 completes the data acquisition process. If the CPU 201 determines that reception has not been completed, the process returns to step S307.

  In this way, the CPU 201 can preferentially acquire data necessary to start drawing the next scene set in advance, so that it is necessary to wait until the game content is provided to the user. Time can be shortened. That is, as described above, the content providing system according to the present embodiment can improve the usability in providing content via communication.

[Embodiment 2]
In the first embodiment described above, the data related to the game content has been described as being transmitted only from the content server 100 to the client terminal 200, but the embodiment of the present invention is not limited to this. In the present embodiment, it is assumed that the client terminal 200 can receive data related to game content from other client terminals 200 than the content server 100.

<Configuration of content provision system>
FIG. 1B shows a system configuration of the content providing system according to the present embodiment. In the figure, client terminals 200a and 200b are connected to the content server 100 via a network 300, and both devices basically receive data relating to game content from the content server 100. However, in the present embodiment, the client terminals 200a and 200b can perform one-to-one communication (for example, peer-to-peer (P2P) communication), and each of the data already received from the content server 100 is another client terminal. Shall be available.

  When P2P communication is performed, communication between client terminals does not need to be performed via a dedicated server. That is, data can be directly transmitted to the client terminal that is the communication partner, and a reduction in traffic (traffic) can be expected. In the present embodiment, an aspect will be described in which the client terminal 200 can acquire data from other clients through P2P communication, thereby efficiently receiving data related to game content in a shorter time.

  Note that the functional configurations of the content server 100 and the client terminal 200 in this embodiment are the same except that the communication unit 205 of the client terminal 200 has a P2P communication function, and thus the description thereof is omitted. In the present embodiment, communication between client terminals is described as being performed by P2P communication. However, the communication method is not limited to this, and short-range wireless communication, ad hoc mode communication, or the like may be used.

<< Data acquisition process >>
Next, specific processing will be described with reference to the flowchart of FIG. 4 for data acquisition processing for acquiring data related to game content executed in the client terminal 200 of the present embodiment. The processing corresponding to the flowchart can be realized by the CPU 201 reading, for example, a corresponding processing program stored in the ROM 202, developing it in the RAM 203, and executing it. Note that the data acquisition process will be described as being started when, for example, a scene switching event occurs in game content and it is necessary to receive new data from the content server 100.

  In the data acquisition process of the present embodiment, the same reference numerals are assigned to the steps for performing the same process as the data acquisition process of the first embodiment, and the description thereof is omitted. Hereinafter, the characteristic process of the present embodiment is described. Only will be described.

  In step S <b> 401, the CPU 201 reads management information stored in the RAM 203, transmits the management information to the communication unit 205, and transmits the management information to other client terminals currently connected to the content server 100. Information on other client terminals currently connected to the content server 100 may be provided from the content server 100 in the execution of the game process, for example. The information includes information necessary for connection to another client terminal such as a global IP address of the other client terminal.

  In step S402, the CPU 201 performs processing for a predetermined period as a reception period of management information indicating data held in the data holding unit 206 of the other client terminal from another client terminal currently connected to the content server 100. stand by. At this time, when the CPU 201 receives management information from another client terminal, the CPU 201 stores the management information in the RAM 203 in association with information that identifies the received client terminal. After the elapse of the predetermined period, the CPU 201 moves the process to S403.

  In step S <b> 403, the CPU 201 causes the request data determination unit 204 to determine request data acquired from the content server 100 or another client terminal 200. Further, after determining the requested data, the requested data determining unit 204 determines which device is requested for each requested data. Specifically, the request data determination unit 204 refers to management information about the other client terminals 200 stored in the RAM 203, and determines an acquisition destination device so that each data can be distributed and acquired.

  In step S404, under the control of the CPU 201, the request data determination unit 204 transmits a first data provision request via the communication unit 205 to the device from which each data determined in step S403 is acquired, and the process proceeds to step S303. .

  If it is determined in S305 that the reception of the first data has been completed, the CPU 201 moves the process to S405. In step S405, under the control of the CPU 201, the request data determination unit 204 transmits a second data provision request to the device from which each data is acquired via the communication unit 205, and the process proceeds to step S307.

  By doing in this way, when there is another client terminal connected to the content server 100, the client terminal 200 according to the present embodiment acquires the game content by acquiring data from the other client terminal. As a result, it is possible to reduce the time required for acquiring the data according to the above.

  In the data acquisition process described above, the management information is shared with other client terminals only in S401 and S402. However, the embodiment of the present invention is not limited to this. For example, when cooperative play is being performed in an online game for multi-users, each client terminal used by a user who is performing cooperative play is making similar progress. That is, if the game progress is the same, the other client terminals are considered to execute the data acquisition process at the same timing, so that the other client terminals are used for drawing the next scene at the start of the data acquisition process. It is conceivable that the data to be stored is not retained. In such a case, when the management information is updated as data is received, the CPU 201 may transmit the management information to another client terminal connected to the content server 100.

  Further, the content server 100 refers to the provision request received from each client terminal, and when the same data is requested from a plurality of client terminals, the order of transmitting the data to each client terminal is changed. Also good. In other words, by intentionally changing the data held by the client terminal connected to the content server 100, data acquisition by P2P communication is efficiently used, and it is necessary to acquire data used for drawing the next scene. The total time may be shortened. At this time, intentional distribution of data transmission may be performed in units of files, or may be performed by distributed transmission of data obtained by dividing one file, such as an encoding unit.

  The present invention is not limited to the above-described embodiment, and various changes and modifications can be made without departing from the spirit and scope of the present invention. Therefore, in order to make the scope of the present invention public, the following claims are attached.
