A commentary video generation method and apparatus, server, and storage medium. The method includes: obtaining a game instruction frame, the game instruction frame including at least one game operation instruction, and the game operation instruction being used for controlling a virtual object; generating a commentary data stream based on the game instruction frame, the commentary data stream including at least one piece of commentary audio describing a game event, and the game event being triggered during the virtual object performing the in-game behavior; rendering a game screen based on the game instruction frame to generate a game video stream, the game video stream including at least one game video frame; and combining the commentary data stream with the game video stream, the game video frame and the commentary audio corresponding to the same game event in the commentary video stream being aligned in time.

A method is disclosed including setting, at a server, a server VSYNC signal to a server VSYNC frequency defining a plurality of frame periods. The server VSYNC signal corresponding to generation of a plurality of video frames at the server during the plurality of frame periods. The method including setting, at a client, a client VSYNC signal to a client VSYNC frequency. The method including sending a plurality of compressed video frames based on the plurality of video frames from the server to the client over a network using the server VSYNC signal. The method including decoding and displaying, at the client, the plurality of compressed video frames. The method including analyzing the timing of one or more client operations to set the amount of frame buffering used by the client, as the client receives the plurality of compressed video frames.

A method and a system for receiving a user's selection of a content, retrieving data about the content, tracking content consumption, launching a reactive module based on input from the user, registering a timestamped response of the user, the response comprising a graphic symbol is provided. The method may be further comprise receiving content-retrieving information from a second user, searching contents to identify a candidate for the second user's consumption, receiving a selection of a content from the candidate, tracking a position of the content that is selected and being consumed by the second user, launching the reactive module on a second client device based on input from the second user. The virtual platform provides an electronic venue of dynamic communications for content consumers, where users experience pseudo-realtime interactions by seeing the virtual platform's reconstruction of other users' responses that shows reacting users' emotional status.

An apparatus configured to, based on first imagery (301) of at least part of a body of a user (204), and contemporaneously captured second imagery (302) of a scene, the second imagery comprising at least a plurality of images taken over time, and based on expression-time information indicative of when a user expression of the user (204) occurs, provide a time window (303) temporally extending from a first time (t−1) prior to the time (t) of the expression-time information, to a second time (t−5) comprising a time equal to or prior to the first time (t−1), the time window (303) provided to identify at least one expression-causing image (305) from the plurality of images of the second imagery (302) that was captured in said time window, and provide for recordal of the at least one expression-causing image (305) with at least one expression-time image (306) comprising at least one image from the first imagery (301).

Methods, systems, and apparatuses for content deliver, buffer management and synchronization are described herein. Content being played back on a playback platform is analyzed and based on the analysis, asynchronous playback of the content may be determined. A source buffer flush may be performed to correct the asynchronous playback. After the source buffer flush is performed, content segments may be written to the source buffer so that playback of the content on the playback platform resumes with synchronized audio and video.

A device, system, and method perform an automatic change over for transport streams. The method is performed at an output server. The method includes selecting a first transport stream. The method includes generating a first portion of an output based on the first transport stream. The method includes selecting a second transport stream. The method includes determining a frametime to synchronize first packets of the first transport stream to second packets of the second transport stream. The frametime is based on a start time of a content item included in the first transport stream and the second transport stream and a completed progression of the content item using the first transport stream. The method includes determining a location in the second transport stream based on the frametime. The method includes generating a second portion of the output based on the second transport stream starting at the location.
