METHOD OF PROVIDING BROADCASTING SERVICE AND PLAYING BROADCAST BY USING OBJECT STATE TRANSMITTING METHOD

摘要

Provided is a method of providing a broadcasting service and playing a broadcast by using an object state transmitting method, in which a data capacity of a video may be remarkably reduced to transmit a broadcasting image and image data of the broadcasting image may be received and played. Accordingly, according to the method of providing a broadcasting service and playing a broadcast by using an object state transmitting method, a broadcasting image having a small data capacity may be transmitted, received and provided at a high image quality at the same time.

1. A method of providing a broadcasting service by using an object state transmitting method, wherein a broadcasting server transmits image information to a play terminal so that the play terminal receives the image information in real-time and plays the image information, the method comprising:
(a1) when things, characters, and backgrounds appearing in three-dimensionally defined virtual space, defined as objects, appear in virtual space of a broadcasting image, generating identification numbers of the objects, numerical data of position coordinates and directions of the objects in the virtual space, and serial numbers of image frames, in which the objects appeared, as appearance information and transmitting the appearance information to the play terminal so that the play terminal creates the objects disposed in the virtual space in units of image frames to render the image frames on a screen, wherein the generating and transmitting of the appearance information is performed by the broadcasting server; (a2) when an object that appeared in (a1) moves in the virtual space of the broadcasting image, creating numerical data defining a motion of the object corresponding to a serial number of the image frame as motion state information and transmitting the motion state information to the play terminal so that the play terminal creates the motion of the object in units of image frames and renders the image frames on the screen, wherein the creating and transmitting of the motion state information is performed by the broadcasting server; and (a3) when an object that appeared in (a1) exits from the virtual space, transmitting the identification number of the exiting object and a serial number of an image frame in which the object exits, to the play terminal as exit information so that the play terminal removes the exiting object from the virtual space and creates an image frame to render the image frame on the screen, wherein the transmitting of the exit information is performed by the broadcasting server.
