Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a schematic diagram showing a configuration example of a content display system according to an embodiment of the present invention. In FIG. 1, the content creation device 1 transmits content data to the terminal device 2 via the communication network 3. The terminal device 2 receives content data from the content creation device 1 via the communication network 3 and displays moving image content using the received content data.

  First, the content creation device 1 shown in FIG. 1 will be described. In FIG. 1, the content creation device 1 includes a mesh model data creation unit 11, a motion data creation unit 12, a storage unit 13, and a communication unit 14. The mesh model data creation unit 11 performs mesh model data creation processing. The motion data creation unit 12 performs motion data creation processing. The storage unit 13 stores data. The communication unit 14 transmits / receives data to / from the terminal device 2 via the communication network 3. Each part 11, 12, 13, 14 is connected so that data can be transmitted and received.

  The mesh model data creation unit 11 performs scalability processing on mesh model data constituting the content data, and creates mesh model data having a fine level hierarchical structure. Hereinafter, the scalability process for mesh model data will be described.

FIG. 2 is a conceptual diagram for explaining mesh model data having a fine level hierarchical structure according to the present embodiment. 2, the mesh model M ⁰ is the base layer. Mesh model M ¹ is up Layer 1-definition level is raised one step from the base layer. The mesh model M ⁿ is an up-layer n whose fineness level has increased n levels from the base layer. In the example of FIG. 2, the mesh model M ⁰ has 150 polygons. Each time the fineness level increases by one (n increases by 1), the number of vertices increases by one and the number of polygons increases by two.

The mesh model data creation unit 11 creates mesh model data “M ⁰ , vspl ₀ , vspl ₁ ,..., Vspl _i ,..., Vspl _n−1 ” from the mesh model M ⁰ by scalability processing. . vspl _i is data for creating the mesh model M ⁱ from the mesh model M ⁱ⁻¹ . Therefore, if the mesh model M ^i-1 and the data vspl _i exist, the mesh model M ⁱ can be created.

Figure 3 is a conceptual diagram illustrating the mesh model M ⁰ of the base layer. The mesh model M ⁰ has information on the vertex (Vertex 1, 2,...) And each polygon (Face 1, 2,...). FIG. 4 is a conceptual diagram for explaining the data vspl _i . Data V spl _i is a vertex of the mesh model ^M i-1 _100 (vertex _V s in the example of FIG. _{4, V l, V r)} , and, changing the mesh model ^M i-1 _100 at the apex of the mesh model ^M i _110 Information of the vertexes (vertices V _s ′, V _t ′ in the example of FIG. 4).

  Returning to FIG. The motion data creation unit 12 performs scalability processing on the skeleton motion data constituting the content data, and creates skeleton motion data having a fine level hierarchical structure. Hereinafter, the scalability process for the skeleton motion data will be described.

  FIG. 5 is a conceptual diagram for explaining skeleton motion data having a fine-level hierarchical structure according to the present embodiment. In FIG. 5, the base layer MB is composed of beat frames at the beat time of the skeleton motion data. The upper layer MU1 above the base layer MB is composed of intermediate frames between adjacent beat frames. For example, an intermediate frame 203 between adjacent beat frames 201 and 202 belongs to the upper layer MU1. Intermediate frames between adjacent frames between layers sequentially constitute an upper layer. For example, the intermediate frame 204 between the beat frame 201 and the frame 203 adjacent between the base layer MB and the up layer MU1 constitutes the up layer MU2 that is one above the up layer MU1. Similarly, the frame 203 adjacent to the up layer MU1 and the base layer MB and the intermediate frame 205 of the beat frame 202 constitute an up layer MU2 that is one above the up layer MU1.

  The motion data creation unit 12 creates base layer data and difference data between layers through scalability processing. The base layer data is data of all beat frames. The base layer data is {IB, PB}. However, IB is an identifier (ID) of a beat frame and is “IB = {Ts, Ts + K, Ts + 2K,..., Ts + iK,..., Ts + mK}”. Ts is the first beat time, and K is the interval between beats. PB is angle data and body position data of all joints of the beat frame.

Difference data between layers “MU _l = {IU _l , PU _l }” is calculated by the following equation.

Frame-up layer MU1 can create the base layer data {IB, PB} from the difference data MU ₁ Tokyo. Similarly, it frames up layer MU2 can create the base layer data {IB, PB} from difference data MU ₁ and the difference data MU ₂ Prefecture.

  Returning to FIG. The storage unit 13 includes the “mesh model data having a fine level hierarchical structure” created by the mesh model data creating unit 11 and the “skeleton motion data having a fine level hierarchical structure” created by the motion data creating unit 12. The configured content data is stored. The communication unit 14 transmits the content data in the storage unit 13 to the terminal device 2.

  Next, the terminal device 2 shown in FIG. 1 will be described. In FIG. 1, the terminal device 2 includes a terminal capability estimation unit 21, a display control unit 22, a display unit 23, a storage unit 24, a communication unit 25, and an operation unit 26. The terminal capability estimation unit 21 performs terminal capability estimation processing. The terminal capability estimation process includes an estimation process in an initial state and an estimation process in a dynamic state. The display control unit 22 performs display control processing. The display unit 23 displays moving image content on the display screen. The storage unit 24 stores data. The communication unit 25 transmits / receives data to / from the content creation device 1 via the communication network 3. Each part 21, 22, 23, 24, 25, 26 is connected so that data can be transmitted and received.

  The communication unit 25 stores content data received from the content creation device 1 in the storage unit 24. This content data is composed of mesh model data having a fine level hierarchical structure and skeleton motion data having a fine level hierarchical structure.

  The terminal capability estimation unit 21 estimates the information processing capability of the terminal device 2 itself. The information processing capability is estimated by initial estimation and dynamic estimation. FIG. 6 is a flowchart of the initial estimation process according to the present embodiment. With reference to FIG. 6, the operation | movement which concerns on the initial stage estimation process of the terminal capability estimation part 21 is demonstrated. The initial estimation process of FIG. 6 is executed when the terminal device 2 is not displaying moving image content.

(Step S11)
The terminal capability estimation unit 21 uses the content data in the storage unit 24 to measure the parsing time between the mesh model data and the skeleton motion data. The parsing time is a time required for the process of associating the mesh model data with the skeleton motion data. The purging time is mainly correlated with the CPU capacity. As a method for measuring the purging time, for example, a process of associating the mesh model M ⁰ in the mesh model data with the first beat frame in the skeleton motion data is performed, and the time required for this process is measured. The contents of the correspondence is vertices of the mesh model M ^0, and the input of the polygon and texture, and the input of the bone of the first beat frame, a correspondence of the bones and polygons.

  The purging time is assumed to be proportional to the calculation time for moving the polygon according to the bone movement (angle) and the display time of the polygon and the texture.

(Step S12)
The terminal capability estimation unit 21 compares the purging time measured in step S11 with a predetermined threshold value. There are two threshold values TH1 and TH2 (TH1 <TH2). Note that the values of the thresholds TH1 and TH2 are changed according to the number of polygons. This is because the greater the number of polygons, the longer the purging time.

(Step S13)
The terminal capability estimation unit 21 determines the information processing capability of the terminal device 2 based on the comparison result of step S12. If the purging time is less than TH1, it is determined that the information processing capability is high. If the purging time is greater than or equal to TH1 and less than TH2, it is determined that the information processing capability is medium. If the purging time is greater than or equal to TH2, it is determined that the information processing capability is low. The terminal capability estimation unit 21 stores the information processing capability estimation result “high, medium, or low” of the terminal device 2 in the storage unit 24.

  FIG. 7 is a flowchart of the dynamic estimation process according to the present embodiment. With reference to FIG. 7, the operation | movement which concerns on the dynamic estimation process of the terminal capability estimation part 21 is demonstrated. The dynamic estimation process of FIG. 7 is executed when the terminal device 2 is displaying moving image content.

(Step S21)
The terminal capability estimation unit 21 measures the number of display frames that the display unit 23 displays on the display screen.

(Step S22)
The terminal capability estimation unit 21 determines whether it is dynamic estimation timing. The dynamic estimation timing occurs at a predetermined cycle. This predetermined period is, for example, one frame interval of the moving image content.

(Step S23)
The terminal capability estimation unit 21 calculates the average frame rate using the measured number of display frames at the dynamic estimation timing. The average frame rate may be calculated using the number of display frames in a certain period, or may be calculated using the total number of display frames from the display disclosure time.

(Step S24)
The terminal capability estimation unit 21 compares the average frame rate calculated in step S23 with a predetermined threshold FTH.

(Step S25)
The terminal capability estimation unit 21 updates the information processing capability of the terminal device 2 stored in the storage unit 24 based on the comparison result in step S24. If the average frame rate is less than FTH, the information processing capability is lowered by one step. If the average frame rate exceeds FTH, the information processing capability is increased by one step. When the average frame rate is the same as FTH, the information processing capability is not changed.

  Returning to FIG. Based on the information processing capability estimated by the terminal capability estimation unit 21, the display control unit 22 determines the hierarchy of mesh model data or skeleton motion data used for displaying moving image content by the display unit 23. The information processing capability estimated by the terminal capability estimation unit 21 is stored in the storage unit 24. The display control unit 22 instructs the display unit 23 which layer of the mesh model data is used and which layer of the skeleton motion data is used based on the information processing capability stored in the storage unit 24.

  When the display unit 23 is displaying moving image content, the information processing capability stored in the storage unit 24 is updated by the dynamic estimation process of the terminal capability estimation unit 21. For this reason, the display control unit 22 changes the display unit 23 based on the information processing capability stored in the storage unit 24 periodically or when the information processing capability stored in the storage unit 24 is updated. On the other hand, it indicates which layer of the mesh model data is used and which layer of the skeleton motion data is used.

  FIG. 8 is an example of a correspondence relationship between the estimation result of the information processing capability of the terminal device and the hierarchy of mesh model data and skeleton motion data used for displaying moving image content. In this example, the correspondence relationship between the mesh model data and the skeleton motion data used for the display is also shown in accordance with the display content of the moving image content according to the user request.

  In FIG. 8, when the estimation result of the information processing capability of the terminal device 2 is high, both the mesh model data and the skeleton motion data use the entire hierarchy. In this case, the display content of the moving image content according to the user request is not relevant.

  When the estimation result of the information processing capability of the terminal device 2 is medium, the layer to be used is changed according to the display content of the moving image content according to the user request. When the display content of the moving image content according to the user request is the entire display of the moving image content, both the mesh model data and the skeleton motion data use only the base layer and the upper layer one above the base layer. This is because the estimation result of the information processing capability of the terminal device 2 is not so high, so that the smoothness of the display of the moving image content is maintained instead of reducing the definition level by reducing the amount of data used for displaying the moving image content. On the other hand, when the content of the moving image content displayed by the user request is a partial display of the moving image content, both the mesh model data and the skeleton motion data use the entire hierarchy. This is because the estimation result of the information processing capability of the terminal device 2 is not so high, but since it is a partial display of moving image content, the amount of data is reduced even if the entire hierarchy is used. Maintain a fine level to suit.

  When the estimation result of the information processing capability of the terminal device 2 is low, the layer to be used is changed according to the content of the moving image content displayed by the user request. When the display content of the moving image content according to the user request is the entire display of the moving image content, only the base layer is used for both the mesh model data and the skeleton motion data. Since the estimation result of the information processing capability of the terminal device 2 is low, the amount of data used for displaying the moving image content is reduced as much as possible to maintain smooth display of the moving image content. When the display content of the moving image content according to the user request is a partial display of the moving image content, both the mesh model data and the skeleton motion data use only the base layer and the upper layer that is one above the base layer. This is because the estimation result of the information processing capability of the terminal device 2 is low, so it is desirable to reduce the amount of data used for displaying moving image content as much as possible, but to maintain a fine level to some extent so as to be suitable for enlarged display by partial display. is there.

  Returning to FIG. The display unit 23 displays the moving image content on the display screen using the mesh model data layer and the skeleton motion data layer specified by the display control unit 22. Note that the moving image content is, for example, a predetermined character animation.

  According to the above-described embodiment, it is possible to contribute to smooth display of moving image content according to a request (performance request or display content by a user request) in the terminal device 2. Further, by determining the hierarchy to be used for moving image content display based on the dynamic estimation result of the information processing capability of the terminal device 2, the information processing capability can be reduced even when the information processing capability is reduced due to processing overhead in the terminal device 2. The moving image content can be smoothly displayed using the corresponding hierarchy. Examples of the processing overhead in the terminal device 2 include multitask processing in the terminal device 2 and an operation of enlargement or reduction of the moving image content display by the user.

  As mentioned above, although embodiment of this invention was explained in full detail with reference to drawings, the specific structure is not restricted to this embodiment, The design change etc. of the range which does not deviate from the summary of this invention are included.

  For example, in the above-described embodiment, the purging time is used for the initial estimation of the information processing capability of the terminal device, but the present invention is not limited to this. For example, an information processing capability table of the terminal device may be created in advance as the initial estimated value and stored in the storage unit. As the information processing capability table, for example, an information processing capability table is created for each manufacturer or type of terminal device. In addition, the information processing history such as the display history of the moving image content in the terminal device is recorded, and the result of learning the information processing capability of the terminal device using the history is registered in the information processing capability table of the terminal device in advance. May be.
