An intelligent trust enabler system for a 5G IoT (fifth-generation Internet of Things) environment includes: an IoT trust enabler mounted on an edge and gateway on a fifth-generation (5G) IoT infrastructure, for providing trust information based on data collected from IoT devices and performing operation and management of connected IoT resources; and an IoT trust agent for providing a legacy environment for the IoT trust enabler.

5G-IoT intelligent trust enabler system

A coding and Incentive-based distributed computing management system includes: a parameter server that publishes a gradient descent computation task to update parameters of distributed computing, sends the published task to end devices, and groups end devices into clusters by receiving related information from the plurality of end devices, determines the number of stragglers in each cluster and sends the number of stragglers to the end devices, along with an encoding scheme for gradient descent computation, and distributes incentive to the end devices based on encoded results and the end devices that receive the published task from the parameter server, sends an intention to participate in the published task and related information to the parameter server, determines CPU-cycle frequencies by receiving information on the grouping of the end devices and related information from the parameter server, and performs encoding for gradient descent computation and send a computed gradient to the parameter server.

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.

A method and a system for media synchronization are described. The method for media synchronization may include collecting stream source information, generating network delay information between stream sources by performing a delay test between the stream sources, setting synchronization information of a stream source corresponding to a specific channel based on the collected stream source information and the network delay information, measuring network delay with at least one user terminal to receive the stream source, and updating the synchronization information based on the measured network delay.

Method and system for media synchronization

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.
