Abstract: A method and a system for correcting a field of view (FOV) using tilt information of a user terminal upon playback of a 360-degree image. The method includes requesting to load a 360-degree image, correcting at least one of a tilt of the mobile terminal and a sensing value associated with a gesture input of the mobile terminal, for determining an FOV of the 360-degree image, with respect to the 360-degree image, and playing back the 360-degree image by exposing an FOV depending on at least the corrected tilt or the corrected sensing value.

Abstract: Disclosed is a method and system for re-directing a dynamic instance hosting service of a virtual object. The dynamic instance hosting service re-directing system may include a spatial information controller configured to determine whether an instance of an Internet of Things (IoT) device is movable based on spatial information of the IoT device using an instance hosting function; and an instance resource controller configured to manage available instance resources associated with the IoT device and an external service for an instance movement of the IoT device.

Abstract: Disclosed is a method for providing a content, the method including extracting at least one still image from video included in the content, extracting audio, which corresponds to the still image, and generating a script corresponding to the audio, adding a caption to the still image based on the generated script, and providing the content in response to a request of consumption to the content and providing the caption-added still image for the video that is streaming in real time.

Abstract: An advertisement display determining method configured as a computer may include: collecting situation information from at least one sensor of a digital signage device; registering advertisement content based on setting information input from an advertiser or campaign setting information input to a campaign template selected by the advertiser; extracting the advertisement content corresponding to the situation information in response to matching between the setting information input from the advertiser or the campaign setting information input from the advertiser and the situation information; and providing the extracted advertisement content to the digital signage device, and logging the advertisement content for differentially determining a charge based on the situation information.

Abstract: A service method and a system for managing a transaction using application properties are provided. The service system includes a cloud-based virtual object transaction manager. The virtual object transaction manager includes when a virtual object of an IoT device is generated, an application program interface (API) registering unit configured to register an interface provided form the virtual object as an API format and an API use permission managing unit configured to manage use permission of an API according to each virtual object of an IoT device registered on a cloud service.

Abstract: A service system in an IoT environment is provided. The service system includes an instance manager configured to manage generation and operation of an instance for a virtual object corresponding to an IoT device. The instance manager includes an instance pool configured to pool the instance, a message router configured to filter a data stream according to the instance and to transmit the filtered result value together with the data stream, and an instance lifecycle manager configured to reuse the instance pooled in the instance pool according to the filtered result value or to skip calling of an instance according to the data stream.
