The operations include separating an object video and an original background video from video data input to a first video call screen of an electronic device during a video call; generating new video data by synthesizing a panoramic video image and the object video such that the new video data includes the object video and includes the panoramic video image as a replacement background video; and displaying, on the first video call screen, the new video data such that a location of the panoramic video image of the new video data moves in response to motion information of a user.

Abstract: A computer-implemented billing method including displaying, on a video call screen, video data related to a counterpart terminal with which a video call is connected, recognizing reaction information input from the counterpart terminal based on the video data related to the counterpart terminal displayed on the video call screen, and generating billing data related to the recognized reaction information of the counterpart terminal based on a billing policy may be provided.

Abstract: Disclosed is a method, system, and non-transitory computer-readable record medium for filtering chatroom messages. The message processing method includes setting at least one filter condition related to a chatroom for at least one chatroom on a messenger; and displaying a message corresponding to the filter condition among messages included in the chatroom.

Abstract: A method, an apparatus, and a non-transitory computer-readable record medium for providing content based on a user reaction related to a video are provided. A content providing method includes: providing a user interface that comprises a plurality of interaction types to input one or more user reactions to a video during a playback of the video; storing a user reaction of a specific interaction type, which is input through the user interface among the plurality of interaction types, in association with a specific frame of the video based on a reaction input time at which the user reaction is input; and providing content related to the specific frame in response to a playback request associated with the user reaction.

Abstract: 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.

Abstract: A non-transitory computer-readable recording medium storing instructions that, when executed by a processor, cause the processor to set a communication session in which a plurality of users participate through a server, generate data for a virtual space, share motion data related to motions of the plurality of users through the communication session, generate a video in which avatars following the motions of the plurality of users are represented in the virtual space, based on the motion data, and share the generated video with the plurality of users through the communication session.

Abstract: Disclosed is a reaction display method performed by a computer apparatus including processing circuitry, the reaction display method including displaying, by the processing circuitry, a content sharing screen with a voice over Internet protocol (VoIP) call screen during a VoIP call, the content sharing screen including shared media content, and a user of the computer apparatus participating in the VoIP call, receiving, by the processing circuitry, a position at which a reaction is input from the user during the VoIP call, sending reaction information and the position to at least one other user participating in the VoIP call, the reaction information corresponding to the reaction, and displaying an indication of the reaction on the VoIP call screen or the content sharing screen based on the position.

Abstract: A method, a system, and a non-transitory computer-readable record medium are provided to display content of interest. A content display method may include analyzing a user interest based on a user activity on an application; generating a customized content in response to receiving from a server, information that matches the user interest; and displaying the customized content through an interface related to a specific event when the specific event occurs on the application.
