A system includes at least one processor having a learning part for learning a deep neural network (DNN)-based style transfer model by using an image of a specific style to be learned, the style transfer model being a DNN model having an architecture in which the number of deep layers is reduced through transfer learning using a previously learned result.

Optimization technique for forming DNN capable of performing real-time inference in mobile environment

A method for playing streaming content includes requesting a playlist from a streaming server for providing a streaming service; receiving, in response to the request, a streaming fragment template provided by the streaming server; separating the playlist, a manifest file, and track information included in the streaming fragment template; and processing the play of the streaming content requested from a player module by using at least one of the playlist, the manifest file, and the track information.

Method and system for playing streaming content

A method for implementing a seamless switching mode between channels in a multi-stream live transmission environment includes receiving in a single stream, a composite image in which images of multiple channels are synthesized into a single image, composing a view mode having a layout including the images of the multiple channels using the composite image, and changing a layout of the view mode using the composite image.

Method, system, and computer readable recording medium for implementing seamless switching mode between channels in multi-stream live transmission environment

A video transmission control method for adaptive data transmission includes predicting a network state through machine learning using information related to video transmission as a feature in a real-time video streaming environment; and determining an option for controlling video transmission on the basis of the predicted network state.

Method and system for adaptive data transmission

A method for playing back streaming content according to an embodiment may include a step in which a streaming player client sets an initial bitrate for a player module playing back streaming content; a step in which the streaming player client delivers, from the player module to a streaming server, a manifest file request for the streaming content; a step in which a local proxy server edits the manifest file delivered from the streaming server, the manifest file being edited on the basis of the set initial bitrate; and a step in which the local proxy server delivers the edited manifest file to the player module through the streaming player client.

Method and system for playing back streaming content using local streaming server

Methods and systems for providing multi-track video content includes, receiving a user request for multi-track video, the multi-track video including a plurality of videos, each of the plurality of videos corresponding to a track, each of the plurality of videos being divided into time-based video segments; requesting a first video of the plurality of videos, the first video corresponding to a first track of the multi-track video; receiving first video segments corresponding to the first video; sequentially transferring the first video segments to a player for displaying the sequentially transferred first video segments; receiving second video segments of a second video of the plurality of videos instead of receiving the first video segments, the second video segments corresponding to a second track of the multi-track video; and sequentially transferring the second video segments to the player for displaying the sequentially transferred second video segments.

Service method and system for providing multi-track video contents

Provided is a method and system for measuring a bandwidth of a network based on a buffer and adaptively transmitting data in a real-time live environment. The method includes verifying a duration of data storage in a buffer configured to manage a data packet in a real-time live environment; and measuring a bandwidth of a network based on the duration of data storage in the buffer and adaptively controlling a data transmission rate based on the bandwidth.

Bandwidth estimation based on buffer and adaptive bitrate publish in real-time live environment

Disclosed herein are a method and apparatus for providing a toolbar service. The method for providing a toolbar service in a system connected to a user client via a network includes generating a file which can be edited by a user and includes at least one item information for defining an attribute of an interface displayed in a toolbar; receiving a request for download of a toolbar application from the user client; and transmitting the toolbar application including the file to the user client. The toolbar application installed in the user client updates the file according to a user's request for editing an item, parses the updated file to dynamically generate the interface of the toolbar. It is possible to provide a variety of interfaces according to a theme.

Method and apparatus for providing toolbar service

Provided is a composition-based exposure measuring method and apparatus for measuring an exposure degree of an object included in an image, including: receiving an input of the image; measuring an exposure amount of a pixel located in a region determined based on a composition, among pixels of the received image; and determining the exposure degree of the object based on the measured exposure amount.

Exposure measuring method and apparatus based on composition for automatic image correction

Disclosed are a system for transmitting, receiving, and posting messages, a method thereof, and a computer readable recording medium for recording a program for realizing the method in a computer. When a service subscriber generates a message and transmits the message, a first record and a second record are generated based on the transmitted message, the generated first and second messages are respectively stored and then transmitted to user terminals of an addresser and an addressee, and the user terminals display the transmitted message contents together with previously transmitted related message contents based on record fields. In this instance, the addressee is restricted to be a service subscriber. Therefore, the relationship between the transmitted message and the received message is easily detected, the addresser and the addressee conveniently manage the first and second records respectively, and the service is safe from spam mail or viruses since the messages are transmitted and received only between service subscribers.

System for sending, receiving and displaying message, method for sending, receiving and displaying message and computer readable storage medium storing program for that method
