Abstract

A server is disclosed. A server for providing a content to a user terminal device providing a virtual reality service comprises: a communication unit for performing communication with at least one source device and the user terminal device; and a processor for, when a content transmission request for a preconfigured location is received from the user terminal device, receiving a content photographed in a real time from a source device of the preconfigured location on the basis of location information received from at least one source device, and providing the content to the user terminal device.

First claim

What is claimed is:

1. A server for providing a content to an electronic device, the server comprising:
a transceiver; and
one or more processors configured to:
obtain, from a plurality of source devices through the transceiver, location information for locations of the plurality of source devices and authority information for sharing level of content set by the plurality of source devices,
obtain, from the electronic device through the transceiver, a request for content for a specific place,
in response to the request for content for the specific place, obtain a plurality of contents obtained in real time by the plurality of source devices located in the specific place from among the plurality of source devices, based on the obtained location information of the plurality of source devices,
identify a plurality of portions from among the plurality of contents based on the obtained authority information of the source devices located in the specific place, wherein the authority information indicates whether to share only the portion of the content with other devices including the electronic device,
obtain a virtual space by mapping the plurality of portions based on the obtained location information of the plurality of source devices,
obtain a virtual camera in the virtual space through a VR engine, and
transmit an image of the virtual space projected by the virtual camera based on a direction viewed by a user of the electronic device to the electronic device through the transceiver,

wherein each of the plurality of contents comprises video data and audio data, and each of the plurality of portions is video data,
wherein the one or more processors are further configured to decode only a margin region in a region corresponding to a future motion state of the electronic device except for a previously transmitted image and transmit the decoded image to the electronic device,
wherein the one or more processors are further configured to, based on motion information received from a plurality of electronic devices including the electronic device being within a predetermined threshold range, group the plurality of electronic devices into one group, and transmit the image to the plurality of electronic devices,
wherein the one or more processors are further configured to, based on a start point and an arrival point in the virtual space being received from the electronic device, obtain an optimal path, obtain background images from the start point to the arrival point according to the obtained path and transmit the background images to the electronic device sequentially,
wherein the one or more processors are further configured to provide a car mode, a walking mode, and a running mode, and
wherein the one or more processors are further configured to obtain audio data from one source device from among the plurality of source devices and obtain video data from the plurality of source devices.

2. A control method of a server for providing a content to an electronic device, the control method comprising:
obtaining, from a plurality of source devices, location information for locations of the plurality of source devices and authority information for sharing level of content set by the plurality of source devices;
obtaining, from the electronic device, a request for content for a specific place;
in response to the request for content for the specific place, obtaining a plurality of contents obtained in real time by the plurality of source devices located in the specific place from among the plurality of source devices, based on the obtained location information of the plurality of source devices;
identifying a plurality of portions from among the plurality of contents based on the obtained authority information of the source devices located in the specific place, wherein the authority information indicates whether to share only the portion of the content with other devices including the electronic device;
obtaining a virtual space by mapping the plurality of portions based on the obtained location information of the plurality of source devices;
obtaining a virtual camera in the virtual space through a VR engine; and
transmitting an image of the virtual space projected by the virtual camera based on a direction viewed by a user of the electronic device to the electronic device,
wherein each of the plurality of contents comprises video data and audio data, and each of the plurality of portions is video data,
wherein the transmitting comprises:
decoding only a margin region in a region corresponding to a future motion state of the electronic device except for a previously transmitted image, and
transmitting the decoded image to the electronic device,

wherein the transmitting comprises:
based on motion information received from a plurality of electronic devices including the electronic device being within a predetermined threshold range, grouping the plurality of electronic devices into one group, and
transmitting the image to the plurality of electronic devices, wherein the transmitting comprises:
based on a start point and an arrival point in the virtual space being received from the electronic device, obtaining an optimal path, obtaining background images from the start point to the arrival point according to the obtained path, and
transmitting the background images to the electronic device sequentially,

wherein the server provides a car mode, a walking mode, and a running mode, and
wherein the obtaining the plurality of contents comprises obtaining audio data from one source device from among the plurality of source devices and obtaining video data from the plurality of source devices.
