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 are a streaming apparatus, a streaming method, and a streaming service system using the streaming apparatus, wherein the streaming apparatus includes: a scheduler configured to generate a modified metafile by modifying a reproduction list file of a metafile; and a server socket configured to transmit the modified metafile when a metafile transmit request is received from a player by operating as a server with respect to the player. Accordingly, delay times of players are substantially the same.

Streaming apparatus, streaming method, and streaming service system using the streaming apparatus

In at least one example embodiment, a content reproducing apparatus includes a display, a memory configured to store at least one program and a processor. The processor is configured to reproduce first moving image content of a plurality of moving image content selected by a user, on a first region of a screen of the display, according to a user input, display a plurality of thumbnail images corresponding to the plurality of moving image content, on a second region of the screen, buffer a second moving image content corresponding to one of the plurality of thumbnail images, the first moving image content being continuously reproduced while the second moving image content is being buffered, and reproduce the second moving image content instead of the first moving image content when the buffering of the second moving image content is completed.

Content reproducing apparatus and method, and content providing apparatus and method

The present invention relates to an adaptive real-time transcoding method and a streaming server therefor to improve service quality by minimizing the disconnection of images in an environment, such as a mobile device, through adaptively changing a set value of a transcoding operation on a media streaming service to match a network environment. The adaptive real-time transcoding method of the present invention is a real-time transcoding method for sequentially transmitting a media data segment, divided and transcoded, in a streaming server to the client side over a network, the method comprising the steps of: determining the fill level of a client-side playback buffer; determining, on the basis of the fill level of the playback buffer, the image quality of media data segments that are not transmitted to the client side; and transcoding the non-transmitted media data segments according to the determined image quality.

Adaptive real-time transcoding method and streaming server therefor

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
