The present invention relates to a video production system for making a high-fidelity video by subjecting a model of a virtual performer to a database and subjecting the subject model to operate according to this model, and a method for live broadcasting over the Internet using the same. The video production system according to the present invention includes a plurality of cameras 19 and cameras 19 installed in different orientations to capture various directions of the position sensor 15 and the subject model 11 for detecting the position of the subject model. ), An image input unit 25 which captures a photographed subject model, a camera switching unit 27 which selects one of the image input unit 25 to input an image of the subject model from various angles, and a position sensor. A position input unit 29 for receiving the position of the subject model read through the model 15; a model motion database 31 in which a model animation of a virtual performer is stored in memory in advance; a first monitor 21 displaying a model motion; The image synthesizer 33 which synthesizes the image of the photographed subject model and the stored background image, the second monitor 23 which displays the synthesized moving image, and the image of the image of the subject model which is being produced and modeled. Checking whether the tooth model is input, recognizing the position of the subject model input from the position sensor 15 and comparing the position of the virtual performer with a predetermined operation position to score the operation of the subject model and displaying it on the first monitor 21. The analyzer 35 includes a video compression unit 37 for compressing a synthesized photograph of the photographed subject model image and the background image, and a storage unit 39 for storing the compressed video on a recording medium. In addition, the present invention captures the motion animation of the virtual performer as a video to store in the best action database 31, storing the background screen, selecting the background to be synthesized, the virtual director first monitor 21 ), The subject model is watching the exemplary operation of the virtual performer displayed on the first monitor 21, and the camera 19 for photographing the image is operated and input to the image input unit 25, the subject model. The operation of is read from the position sensor 15 and the data is input to the position input unit 29, and the position data of the subject model enters the motion analysis unit 35 and is compared with the exemplary operation data output from the exemplary operation database 31. The analyzing step, the operation state of the comparative analysis of the subject model is displayed on the first monitor 21, the image of the input subject model and the selected background image is a video in the image synthesizer 33 Steps that are generated, the synthesized video data is compressed by the video compression unit 37, it consists of the steps that are stored in the recording medium in the storage unit (39). The video production system according to the present invention can be used for internet live broadcasting that a user can directly produce.
