Abstract: Present Invention provides a method of virtual reality image transition configured to implement frame synchronization by controlling transit time among image segmentation expressing virtual reality comprises, (a) determining a key frame distance (KFD) of image segmentation expressing a part of original image for implementing virtual reality, (b) implementing frame synchronization between image segmentation before and after transition by executing a transition of image segmentation only in a key frame among frames composing image segmentation, when reproduced image segmentation is transited as the user's gaze changes.

Abstract: Example embodiments relate to a virtual reality image playing device playing a plurality of virtual reality images to improve the quality of a predetermined area, the virtual reality image comprising, an image input module configured to receive the plurality of virtual reality images stitched from an original image created to realize virtual reality, a multi-rendering module configured to render the plurality of virtual reality images, a synchronization module configured to generate sync information to synchronize the plurality of virtual reality images and an image playing module configured to use the sync information to play the plurality of synchronized virtual reality images.

Abstract: The present invention provides a virtual reality image playing device, the device comprising: a streaming image input unit for receiving, through streaming, one streaming image including multiple virtual reality images captured in different directions at an identical time and at an identical point; a streaming time operation unit for adding a play position of a currently playing virtual reality image to a reference time of a virtual reality image to be newly played; and an image playing unit for playing a streaming image, which has been streamed, on a display device. When virtual reality images captured in different directions are to be played as a gaze of a user changes, the virtual reality image playing device plays multiple virtual reality images by using one streaming image by performing a streaming time jump of a streaming image, using a reference time at which an individual virtual reality image starts.

Abstract: A method of virtual reality image segmentation and a virtual reality image reproducing device are disclosed. The method provides a step of determining the Play FOV of the image segmentation by adding a Guard FOV to the Temporary FOV covered by the temporary image segmentation, in the temporary image segmentation that divides the original image into Nth regions, a step of determining a Virtual Device FOV wider than a Device FOV of the head-mounted display by a predetermined Additional FOV and a step of starting a transit procedure of reproduced image segmentation among a plurality of image segmentation when a predetermined transit standard calculated using the Virtual Device FOV and Play FOV of reproduced image segmentation is satisfied.

Abstract: A smart user equipment (UE) connected to a head mounted display (HMD) worn on a user's head, for playing a video is disclosed. The smart UE includes an operation control module configured to recognize a predetermined user action by a sensor or a camera included in the smart UE and perform a control operation mapped to the user action. The smart UE enables the user to control an operation of the smart UE regardless of whether the HMD includes a separate control means by controlling the smart UE without removing the HMD through the operation control module.

Abstract: A method of requesting a rescue by receiving a disaster alarm signal and a method thereof are disclosed. The method of requesting a rescue by a user terminal, which is connected to a disaster informing server and a rescue center through a communication network, can include receiving a disaster alarm signal from the disaster informing server, generating a corresponding RF signal by receiving the disaster alarm signal, and outputting the generated RF signal. The rescue center can position the user terminal by analyzing an RF response signal sent from a movable rescue apparatus including an RF module for receiving the RF signal.
