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.

Method and system for normalizing platform-adaptive audio

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.

Method and system for processing audio signal

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.

Loudness normalization method and system

A distributed transcoding method includes splitting image content into segments of a fixed interval; allocating the split segments to a plurality of workers and performing parallel transcoding; and concatenating the transcoded segments and merging same into one encoded file.

Distributed transcoding method and distributed transcoding system

A parallel audio transcoding method includes splitting audio into segments of a certain length; performing parallel transcoding by allocating the split segments to a plurality of encoders; and concatenating the segments encoded through the parallel transcoding and merging the same into a single encoded file. Performing parallel transcoding includes inserting additional regions, which overlap and neighbor each of the split segments, and sending the same to the encoders, and merging includes cutting out the additional regions from the encoded stream to create a stream corresponding to the split segments.

Method and system for parallel audio transcoding

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.
