Abstract: 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.

Abstract: A loudness normalization method includes receiving data for playback of content from a server in response to a user's request to play back the content; normalizing the loudness of the content by adjusting the volume output level of a player using volume level metadata of the content included in the received data; and providing the content by playing audio of the content based on the adjusted volume output level of the player.

Abstract: A method for operating a user terminal providing a video slide service includes uploading a UGC video to a server; receiving, from the server, scene metadata information for each reproduction section corresponding to the UGC video; generating a video slide file based on the scene metadata information for each reproduction section; displaying an item corresponding to the video slide file; and displaying a page screen composed of representative image information and subtitle information, for each reproduction section of the UGC video in response to a user selection on the item.

Abstract: A method for processing an audio signal includes setting target loudness; receiving metadata of an audio signal from a server; and adjusting the loudness of the audio signal by using the received metadata, so that the loudness of the audio signal corresponds to the set target loudness.

Abstract: A method for normalizing platform-adaptive audio includes encoding input video content and generating video stream data as original data to store the video stream data in storage; generating loudness metadata for audio data of the video content and storing the loudness metadata in the storage; receiving a request for the video content from a client; searching the storage for video stream data of the video content corresponding to the request, the loudness metadata, and a device profile corresponding to device information included in the request; and transmitting, to the client, a response including the video stream data, the loudness metadata, and the device profile that are found in the storage.

Abstract: Disclosed is a scene meta information generating apparatus including: a subtitle information generating unit configured to detect a plurality of unit subtitles based on a subtitle file related to image contents and correct the plurality of unit subtitles; an audio information generating unit configured to extract audio information from the image contents, detect a plurality of speech segments based on the audio information, and perform speech-recognition on audio information in each speech segment; and an image information generating unit configured to detect a video segment corresponding to each speech segment, perform image-recognition on image frames in the video segment, and selecting a representative image from the image frames.

Abstract: 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.

Abstract: Provided are a content providing server, a content providing terminal, a content providing method. A search for image content is facilitated through a subtitle page including a unit subtitle separated by a subtitle interval, during which a subtitle is displayed in image content, and a representative image extracted from the subtitle interval in the image content, so that a user views the image content according to the user's level of understanding.

Abstract: An operation method of a user terminal for providing a video slide service includes uploading a UGC video to a server; receiving, from the server, scene meta-information for each playback section of the UGC video; generating a video slide file on the basis of the received scene meta-information for each playback section; classifying, according to categories, a plurality of pieces of page information configuring the video slide file; and generating a storybook corresponding to the UGC video on the basis of a plurality of page groups classified according to the categories.
