Disclosed is a method and system for transmitting and reproducing a video of a dynamic bitrate using a plurality of channels. A video transmission method may transferring frames of a video to N encoders using an interleaving scheme, N denoting a first natural number greater than or equal to 2, generating N video streams by encoding the frames using the N encoders, each of the N video streams corresponding to one of the N encoders, and transmitting each of the N video streams as an independent stream.

Reproducing video of dynamic bitrate with a plurality of channels

Disclosed is a method, system, and non-transitory computer-readable record medium for providing an animation function using a sprite joint photographic experts group (JPEG) image. An animated image providing method includes creating, by processing circuitry, a sprite joint photographic experts group (JPEG) image from a video in an animated format, and providing, by the processing circuitry, an animated thumbnail of the video based on the sprite JPEG image.

Method, system, and non-transitory computer-readable record medium for providing animation using sprite JPEG

Disclosed is a live broadcast method and apparatus that may effectively remove delay of a guest broadcast output from a guest side by generating and transmitting an audio of a host and an audio of a guest as individual elementary streams (ESs) in a simultaneous live broadcast transmitted by mixing a host broadcast stream and a guest broadcast stream.

Method, system, and non-transitory computer-readable record medium for cancelling delay of guest broadcasting in live broadcast

Disclosed is a broadcast providing method implemented at an electronic device including processing circuitry. The broadcast providing method includes receiving, by the processing circuitry, a broadcast image from a broadcast server, and generating, by the processing circuitry, a final image by synthesizing the broadcast image with a personalized background image using a chroma key, the personalized background image being personalized for a user of the electronic device.

Method and system for transmitting and reproducing video of dynamic bitrate with a plurality of channels

The present disclosure relates to methods for verifying users performed by at least one processor. The method for verifying users including transmitting, to a user terminal, a plurality of instructions that guide a user to perform a plurality of actions, receiving, from the user terminal, a video photographed in response to the plurality of instructions, determining presence or absence of the user in the video, and verifying the user based on a face of the user extracted from the video in response to a result of the determining indicating that the user is present may be provided.

Method and system for verifying users

Disclosed are methods, systems, and/or a non-transitory computer-readable record mediums for producing a video based on a bot enabling a user feedback. A video production method may include receiving a plurality of images uploaded to a chatroom in response to a bot for a video production being added to the chatroom and the chatroom including at least one user, creating at least one primary video clip using at least two images among the plurality of images, creating a single video using the at least one primary video clip, and providing the created single video to the chatroom.

Method, system, and non-transitory computer-readable record medium for creating video based on user-feedbackable bots

Provided are a method, a system, and a non-transitory computer readable record medium for video quality control. A quality control method may include: receiving a video stream including frames classified into a plurality of frame types based on a reference relationship between the frames for decoding; selecting a frame type among the plurality of frame types; and controlling a quality of the video stream by multiplexing the frames included in the video stream and by outputting one or more of the frames that have the selected frame type.
