Abstract: A content server and method supporting low-latency content streaming are proposed. The content server may include a communication unit and a controller. The communication unit may perform communication with a user terminal. The controller may calculate coordinates for a current user's location and camera pose and create a three-dimensional (3D) space by using terminal data including an image received from the user terminal upon detecting access of the user terminal. Also, the controller may position an object in the created 3D space, render a video reproduced from a user's viewpoint as a two-dimensional (2D) video, generate server data by segmenting the rendered 2D video, and transmit the generated server data to the user terminal.
