Abstract

The present disclosure relates to a method for providing high-resolution virtual reality content based on 5G. The method may include the steps of: receiving virtual reality video data based on 5G communication and assigning it to a first layer; creating a second layer that displays control information of at least one controller; receiving operation information of the at least one controller and determining a collision point between a predetermined object within the virtual reality video data and the control information based on the operation information; assigning combined data including modified control information based on normal data of the collision point to the second layer; and synthesizing the first layer and the second layer to create a final video frame.

Description

Method for providing high-resolution virtual reality content based on 5G The present disclosure relates to a method for providing virtual reality content, and more specifically, to a method for providing high-resolution virtual reality content based on 5G. Virtual Reality (VR) refers to a virtual space generated by a computer that provides a sense of realism through three-dimensional visual effects. The technology for implementing VR processes user input in real time to create the sensation of being in the real world, and it is a next-generation technology that goes beyond multimedia. Virtual reality environments provide users with a realistic sense of immersion, enabling not only the simulation of real objects but also the experience of objects or situations that do not actually exist. Such virtual reality environments can be applied to a wide variety of fields. For example, they are used in truly diverse areas, ranging from engineering fields such as automotive design and simulation experiments to the medical field and cultural content fields. Depending on the perspective, virtual reality (VR) is used interchangeably with terms such as virtual environment, virtual presence, artificial world, virtual world, and cyber space. However, generally speaking, it can be described as a technology that enables artificial experiences by providing a user with a three-dimensional virtual world similar to the real world created by a computer, input means that can be freely manipulated in real time with that virtual world, and sensory feedback means that provide realistic sensations in response to user manipulation. Meanwhile, a method has recently emerged in which a mobile device is integrated with a VR device, and the mobile device performs information processing to generate VR video before transmitting it to the VR device. Although the mobile device—which acts as a computer for information processing—and the VR device for playback are connected via a wire, the ability to integrate the mobile device with the VR device resolves issues caused by cables. However, since mobile devices struggle to run high-spec programs compared to PCs, there is a problem in running high-end VR games or playing high-resolution VR videos.
