Abstract: The present disclosure provides a system, a method, and a device for displaying a content item. The system includes: a video playing terminal, configured to obtain a video and play the video; a content item displaying client, configured to send a content item obtaining request for requesting to obtain a content item related to the video being played by the video playing terminal; and a content item preparation platform, configured to determine a current playing moment of the video played by the video playing terminal, select, from one or more content items corresponding to the video, a content item with a marking moment nearest to the current playing moment, and push the selected content item to the content item displaying client, where the content item displaying client is further configured to display the received content item.

Abstract: An information processing method, a terminal and a server are disclosed. The method includes that: a terminal acquires a first input operation, acquires first input information and first comment information based on the first input operation, and sends the first input information and the first comment information to a server, the first input information includes first data; and if determining that a condition is met, the terminal outputs second comment information sent by the server, the second comment information is the first comment information displayed in a specific display manner.

Abstract: Provided are a method, a device and a system for presenting information. The method includes: acquiring at least one preset information presentation time point in a video to be played and a pre-stored presentation information set associated with video content at the information presentation time point, where the presentation information set corresponds to the information presentation time point in a one-to-one manner; selecting to-be-presented information from the presentation information set corresponding to the information presentation time point based on historical browsing information, to obtain the to-be-presented information corresponding to the information presentation time point; and sending the to-be-presented information corresponding to the information presentation time point to a terminal.

Abstract: Disclosed a live interaction system, an information sending method, an information receiving method and device, and belongs to the technical field of Internet. The system includes at least one client and an interaction platform. the client is configured to send to the interaction platform an interaction instruction for instructing the interaction platform to add an interaction prop into a live stream; and the interaction platform is configured to intercept an image frame from the current live stream, generate instant feedback information according to the image frame and the interaction prop indicated by the interaction instruction, and send the instant feedback information to the client.

Abstract: A video play-based information processing method is realized with a multimedia information processing system, a first client and server for video play, a computer storage medium, and a server used for video play. The method includes: receiving a video content request transmitted by a first client, obtaining a video content requested by the first client, and transmitting the video content to the first client; and during transmission of the video content, transmitting first information associated with the video content and render information of the first information to the first client, for the first client to display the first information associated with the video content via a play interface during playing of the video content. The render information of the first information includes a display start time point, a display duration and display position information of the first information.
