Disclosed are an apparatus and method for transmitting a spatial audio by using multicast that are capable of efficiently transmitting spatial audio data of multiplayer content by using multicast. The spatial audio transmitting apparatus includes a plurality of servers communicatively connected to a plurality of client terminals executing multiplayer real-time content to be separated by a multicast group. A server included in the respective multicast group transmits the first player information to the other servers included in the multicast group in a multicast method so as to be shared when receiving first player information from a client terminal executing the multiplayer real-time content, and mixes spatial audio based on the first player information and the second player information and transmits the mixed spatial audio to the client terminal in a unicast method when receiving second player information from another server included in the multicast group.

Apparatus and method for transmitting spatial audio using multicast

Embodiments of the inventive concept described herein relate to a method and a program for providing augmented reality image using depth data. According to an embodiment of the inventive concept, a method for providing an AR image using depth data includes a step S(a virtual image data receiving step) of receiving, by a client, virtual image data from a server, a step S(a display location determining step) of determining, by the client, a location, at which each pixel is to be displayed in a reality space, based on the depth data, and a step S(a virtual image data displaying step) of displaying the virtual image data in the reality space based on the determined location.

Method and program for providing augmented reality image by using depth data

Disclosed are a method for providing a virtual reality image, and a program using the same. The method includes receiving virtual reality image data from a server and allocating the virtual reality image data to a first layer, generating a second layer containing control information of at least one controller, receiving movement information of the at least one controller, and determining a collision point between a predetermined object in the virtual reality image data and the control information based on the movement information, modifying the control information based on a normal vector at the collision point, and allocating combination data including the modified control information to the second layer, and synthesizing the first layer and the second layer with each other to generate a last image frame.

Method for providing virtual reality image and program using same

Disclosed are a method for transmitting a virtual reality image, a method for reproducing a virtual reality image, and a program using the same. A method for transmitting a virtual reality image includes an operation (S) of creating an initial image frame by a server, an operation (S) of determining image direction data corresponding to the initial image frame, an operation (S) of creating a final image frame by coupling the image direction data to the initial image frame as meta information; and an operation (S) of transmitting the final image frame to a client through wireless communication.

Method for transmitting virtual reality image created based on image direction data, and computer readable medium storing program using the same

Disclosed is a method of playing a virtual reality image, and the method includes receiving, by a client, an image frame from a server, allocating the received image frame to a first layer, generating a second layer including at least one graphic user interface, composing the first layer and the second layer to generate a final image frame, and displaying the generated final image frame.
