The present disclosure describes techniques of processing information flow and synchronously displaying image s, mask frames and comment information. According to the present disclosure, a system processes a first information stream uploaded by a stream pushing terminal to obtain a frame image and mask frame data, the mask frame data corresponding to the frame image and identifying a timestamp offset indicative of a time difference between the mask frame data and a playing timestamp of the frame image. The system synthesizes the frame image and the mask frame data to generate a second information stream; and output the second information stream to a client for synchronously displaying the image frame, a corresponding mask frame, and the comment information.

The present invention provides a method, device and computer-readable storage medium of intelligently buffering a Web video based on a browser, and belongs to a field of the Internet technology. The method, device and computer-readable storage medium of intelligently buffering a Web video based on a browser comprises a browser calculating an available buffer duration based on an available memory size of a buffer and a bit rate; initializing a player based on the available buffer duration; buffering and playing the video to be played using the player. So, the buffer duration can be set flexibly based on different browser platforms and an average bit rate of the video, which can maximize the use of a cache space, and effectively avoid the occurrence of sticking during video playback, and make better use of the bandwidth, so as to greatly improve the user experience.
