Video control method for terminal {ANIMATION CONTROL METHOD FOR TERMINAL}

The present invention relates to a video control method for a terminal, and more particularly, to a video control method for a terminal to control the order of the video to correspond to the user's key input to provide an interactive video service.

In addition to the development of the Internet through a wired network, the provision of video services using wireless terminals is becoming more active. The development of such services is accelerating due to the advantage that the wireless terminal can utilize the information of the wired Internet and receive differentiated services through a connection with a web server providing a specific service. In the video service field applied to such wireless terminals, the development of a simple image service (SIS) solution was developed in 1999 in Korea, and was adopted as a CDMA wireless internet moving picture standard in 2001. Japan's NTT DoCoMo has also adopted GIF as a wireless Internet color video solution.

1 is a diagram illustrating a network in which a video control method for a terminal is implemented. As shown in FIG. 1, the video implementation for a terminal receives image data from a plurality of remote servers 120, 130 and 140 connected to the terminal 100 and 110 and the Internet, stores the image data, and then repeats the stored information. By outputting. The terminal may be any terminal that can be carried and wired and wireless data communication such as a cellular phone 100, a PDA (Personal Digital Assistants: 110), a general wired terminal, and the like.

As a data communication method between the terminal 100 and 110 and the remote server 120, 130 and 140, for example, the SMS (Short Message Service) method can be used. The desired data can be transmitted by sending a small number of bytes several times and collecting them. have. In addition, wireless data communication is possible using the Wireless Application Protocol (WAP) and the HyperText Transfer Protocol (HTTP) protocols.

On the other hand, such a conventional mobile terminal video providing service is a conventional way to display the graphic images sequentially at regular intervals, as in other general animation methods, the general structure of the transmission data (image data) for providing a video is shown in FIG. As shown.

That is, information related to various frames such as the image file information unit 200 in which information such as the size, version, frame number, display interval, etc. of the moving image image is recorded, the expression format of the frame, the frame background information, the movement information of the image in the frame, etc. Information such as the frame information unit 202 to be recorded, an image ID, an image composition order, an image conversion method, and the like, an image conversion information unit 204 for recording a method of expressing an image to be represented in a frame, an image ID, whether to compress an image, and a compression format. Is composed of an image attribute information unit 206 in which data is recorded, and an image data unit 208 in which data such as color, size, and shape of an actual image are recorded.

The data (image data) having such image information is transmitted to the wireless terminal once by wireless communication from the remote server and recorded in the memory, and then repeatedly extracted from the memory and displayed on the screen of the wireless terminal. do. That is, as shown in Figure 3, in the conventional method for implementing a video for a wireless terminal, the image (P1, P2, P3) to download the wireless terminal to indicate a continuous operation to store in the memory, and then stored By displaying the images P1, P2, and P3 sequentially at predetermined intervals, an effect of a moving picture is obtained. In addition, if another image transmission request is received from the wireless terminal, communication with the remote server is resumed, and new moving image data is transmitted from the remote server.

However, since the above-described conventional video implementation method is obtained by sequentially displaying a plurality of images in a predetermined order, the story of the video is monotonous and extremely limited, and it is difficult to implement an interactive video in response to a user input signal. There was an impossible problem.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and an object thereof is to provide a video control method that operates in response to an input signal of a wireless terminal user.

In order to achieve the above object, the video control method for a wireless terminal of the present invention comprises the steps of receiving image data in the form of a frame in the server; Generating key frame information in which frame order change information is recorded in a specific frame among the frames; Receiving the image data and the keyframe information stored in the server to a terminal; Sequentially outputting the received frames to the terminal; If the currently output frame is the key frame, outputting the frames according to the frame order change information recorded in the key frame.

The frame order change information may further include information in which the frame output order is changed according to a user's key input. In the keyframe generation step, the keyframe includes action information and is plural in number. .

In addition, the video control method of the present invention generates video data including frame output state change information so that the output state of the frame is changed according to a user's key input in the video data implementing the video by storing the image data in a frame form. And the frame output state change information includes frame output order change information.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the video control method for a terminal of the present invention.

4 is a system configuration diagram for implementing a video control method for a terminal of the present invention. As shown in FIG. 4, data transmission / reception is possible between the remote servers 120, 130, and 140 and the terminals 100, 110. That is, the remote server 120, 130, 140 stores various video data in the video DB 506 through the video data input unit 500, and when there is a data request from the terminals 100, 110, the data to be transmitted is passed through the encoding processor 502. After the encoding, the transmission / reception processor 504 transmits the data to the terminals 100 and 110.

Meanwhile, the terminals 100 and 110 decode the data received by the transmission / reception processor 510 through the decoding processor 512 and then store the data in the memory unit 514 of the terminal. The stored data is output by the controller 516 to the display unit 518 through a video control process according to a user's key input processing.

The video data is transmitted between the remote server (120, 130, 140) and the terminal (100, 110), the video image data to be transmitted will include the information of the various data necessary for the video implementation. 5 is a diagram illustrating a structure of video data for a terminal of the present invention by way of example. As shown in FIG. 5, data stored in the remote servers 120, 130, and 140 may include an existing image file information unit 400, a frame information unit 402, an image conversion information unit 404, an image attribute information unit 406, and an image data unit ( In addition to 408, it is preferable to further include an image control information unit 410.

The image control information unit 410 is provided with an algorithm for controlling key frame information and loop information, and controls a moving image such as the order of the images, the repetition, the delay speed, and the like according to the input key of the user. The image control data and video image data are stored in the form of a frame in the remote server (120, 130, 140), has a key frame information including the sequence change information of the output frame for a particular frame of the stored frame, and then the terminal (100,110) Is sent on request. 6 is a diagram illustrating a frame structure and a control method for implementing a video for a terminal of the present invention by way of example, and the frame control method according to a user's key input will be described in detail with reference to the drawing shown in FIG. 6.

In order to implement a video on the display unit 518 of the terminals 100 and 110, the still image is allocated to each frame f1, f2, f3, f4, f5, f6, f7, f8, f9, and each frame has a unique value. The frame ID 304 is assigned. In addition, a specific frame is defined as a key frame, and when there is a user's key input in the key frame, the frame has information for branching to a specified frame in response to the input key. The frame control information controlled by the above-described key input is made by reading the information recorded in the plurality of bit strings 312.

Looking at the information on the bit string, the bit control tag 300 is an identification tag for classifying the bit string 312. The number of keyframes 302 indicates the number of keyframes in a frame from f1 to f9. For example, since the bit value of the key frame number 302 is '3', it means that there are three key frames among the total nine frames. The key frame ID 304 bit is a bit indicating the frame ID of the three key frames. Since the respective values are '3', '7', and '9', frames '3', '7', Frame '9' becomes a key frame. The number of actions 306 bits means the number of actions that can occur in a keyframe. For example, an action branched by a user's input key at a specific keyframe may be defined, and an action that is automatically looped to a predetermined frame may be defined when there is no user input key. In this case, since the bit value is '3', it means that there are three actions.

Next, the loop identifier 308 bit and the input key identifier 310 bit are bits for recognizing a user's key input in a key frame. That is, it is determined whether the key input by the user matches the '1' key K1 or the '2' key K2 to determine whether the key corresponds to the bit value of the input key identifier 310. The input key of the user may be any key provided by the terminal, and is operated only in response to a key that generates an action at a specific frame among the input keys. The unnumbered bits are bits indicating the frame to be branched.

Therefore, when reading the control logic for "C-3-3-3-L-1-1-4-2-8" in the bit string of the drawing shown in Fig. 6,

'C' 300 is an identifier for distinguishing the present bit string,

The next '3' means there are 3 keyframes (frame 3, frame 7, frame 9),

The next '3' means a keyframe with the number of actions, and the next '3' means a number of actions, which means that there are three actions in the third keyframe. The subsequent bit strings define one action by making a pair of two bits. In other words, L and 1 bit, 1 and 4 bits, 2 and 8 bits each are a set, there are a total of three actions.

Here, 'L' is a loop identifier 308 to branch the frame, which is a control command to branch to the frame indicated by the following bit. As a result, since the value of the next bit after 'L' is '1', the instruction to branch (L1) to the '1' frame. This loop identifier is a control command executed when no input key is detected from the user.

The next action indicated by '1' and '4' is' 1 'because the input key identifier 310 is' 1'. When the user inputs' 1 'key (K1), the frame indicated by the next bit' 4 'is' It branches to frame 4 '. Continue

The next action indicated by '2' and '8' is '2' because the input identifier 310 is '2'. When the user inputs '2' key (K2), the frame indicated by the next bit '8' is '8'. Branch to frame one.

If you apply control logic like this

"7-2-L-4-1-8" has '2' actions in frame '7'. If there is no user input, branch ('L') is set to frame '4' ( L2), when the user inputs the '1' key K1, the user branches to the '8' frame. In addition, "9-1-L-1" has '1' actions in frame '9', and the branch (L) is made as frame '1' (L3).

In this control logic, if there is a user key input at a non-key frame, the next frame is sequentially set without reacting to the key input. However, when the display interval of the frame is set very small, the user is changed from the normal frame to the key frame during the key input, and thus responds to the key input set in the changed key frame.

7 is a flowchart illustrating a video control method for a terminal according to the present invention.

When the video data including the frame and key frame information is transmitted from the remote server (120, 130, 140) to the terminal (100, 110), in step S100 to determine the structure of the stored data, that is, image information and frame information. The data thus obtained is extracted by the control unit 516 to extract the control logic information of the image in step S102, and the bit string 312 is read. In step S104, the control unit 516 reads the memory unit 514. The frames f1, f2, f3, f4, f5, f6, f7, f8, f9 are aligned and the bit string 312 is stored.

In step S106, the control unit 516 outputs the frames in the memory unit 514 to the display unit 518 in order. The control unit 516 determines whether or not the frame output in step S108 is a key frame, and returns to step S106 if it is not a key frame, and proceeds to step S110 if it is a key frame.

In step S110, a key input is detected from the user. If the input key value is the input identifier 310, that is, the '1' key K1 or the '2' key K2 (hereinafter referred to as the 'control key'), the designated key value is designated. After dividing the display order into frames, step S106 or below is performed. On the other hand, if the control key is not input, the process proceeds to step S114 to determine whether the loop identifier 308 bit is detected. After the determination, if the loop identifier 308 bit is not detected, the flow returns to step S106 to display the frames in order. If detected, the flow advances to step S116 to branch to the frame indicated by the loop bit.

In the next step S118, it is determined whether the frame ID is '0', and if it is not '0', the process returns to step S106, and if it is '0', the control is terminated. These frame IDs can be changed in various ways, and if the time is exceeded, the frame ID can be changed. If a certain frame is repeatedly looped, the frame ID can be changed to force termination. The end point of control may be determined in various ways.

The video control method for a wireless terminal according to the present invention is not limited to the above-described embodiments, and can be modified in various ways within the scope of the technical idea of the present invention. For example, it will be possible to freely use two-way communication according to the user's key input by applying it to a messenger who sends and receives a message using wired network as well as wireless. It can be applied to the role-play game industry to provide application solutions.

According to the video control method for a wireless terminal of the present invention as described above, by controlling the interactive image in response to the user's key input of the video displayed on the wireless terminal, it is possible to send and receive two-way communication to the wireless terminal more There is an effect that can provide content.
