Abstract
An edge server for providing a virtual reality (VR) image is proposed. The server may include a rendering synchronization unit synchronizing a visual field and a margin with a virtual reality device. The server may also include a rendering unit generating a rendered image by rendering a visual field area corresponding to the visual field and a margin area corresponding to the margin based on a rotation center in an entire virtual reality image. The server may further include an encoding unit generating a reduced margin area by dividing a resolution of the margin area by a scaling factor, and encoding the visual field area and the reduced margin area to generate a split virtual reality image including the encoded visual field area and the encoded reduced margin area. The server may further include a streaming transmission unit transmitting the split virtual reality image to the virtual reality device.
