Title:
CONTENT SERVER AND METHOD THAT SUPPORT LOW-LATENCY CONTENT STREAMING
Document Type and Number:
WIPO Patent Application WO/2022/119022
Kind Code:
A1
Abstract:
Disclosed in the present invention are a content server and a method that support low-latency content streaming. The content server of the present invention comprises: a communication unit for communicating with a user terminal; and a control unit which, when a connection of the user terminal is detected, calculates coordinates for a user's current position and a camera pose by using terminal data including an image received from the user terminal and creates a three-dimensional space, positions an object in the created three-dimensional space, renders an image reproduced from the user's point of view into a two-dimensional image, divides same to create server data, and transmits the created server data to the user terminal.
