Problems solved by technology

[0004] Aiming at the problem that the mask information, video information, and barrage information cannot be displayed synchronously in the live broadcast scene, we now provide a method to ensure the processing information flow and display barrage information of the mask information, video information, and barrage information that can be played on the client side. Information method and information flow processing system

Embodiment 1

[0185] refer to Figure 12 As shown, taking the application of the information flow processing system in the live broadcast scene as an example: the user broadcasts the live broadcast through the stream pusher C during 11:00-12:00, and the stream pusher C sends the information stream to the server D from 11:00 , the server D analyzes the received information flow, and identifies the type of each first data unit in the information flow, wherein the first data unit can be a video unit or an audio unit, if the first data unit is a video unit , then decode the video unit, obtain the frame image, the first timestamp t1 and the meta information in the video unit, extract the second timestamp t2 in the meta information, identify the frame image to generate mask frame data, according to the first The timestamp t1 and the second timestamp t2 obtain the timestamp offset of the mask frame data relative to the second timestamp, add the timestamp offset to the mask frame data, and add the ...

Abstract

The invention discloses a method for processing information flow, a method for displaying bullet screen information and an information flow processing system. According to the method, the server sideanalyzes the first information flow uploaded by the flow pushing side to obtain the frame image and the mask frame data corresponding to the frame image and identifying the timestamp offset, and the time difference between the mask frame data and the playing timestamp of the frame image can be determined through the timestamp offset; the frame image and the mask frame data are synthesized to generate a second information flow and the second information flow is output to the client; the client side can obtain the frame image and the mask frame data by analyzing the second information flow, thedisplay moment of the mask frame data is adjusted according to the timestamp offset, the mask frame data, the frame image and the corresponding bullet screen information are displayed at the same time, the watching fluency of a user is guaranteed, and therefore, the barrage information is displayed in the area except the area corresponding to the mask frame data, the barrage is prevented from shielding the main content in the frame image, and the watching experience of the user is improved.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a method for processing information flow and displaying barrage information and an information flow processing system. Background technique [0002] When the user is watching the live broadcast, when there are a large number of viewers, they often encounter a large number of bullet screens swiping the screen, so that the live broadcast screen will be blocked by the bullet screen, affecting the normal viewing of users. If you choose to close the barrage directly, the viewing experience will not be good. If you set the barrage at the top to display, when there are too many barrages, the barrage will be irrelevant to the live content for a short time. [0003] At present, in the on-demand scene, it is usually used to add a mask, so that the bullet chatting is displayed in the area outside the masked area in the playback interface, so as to avoid the bullet chatting from blockin...
