Structure establishes network direct broadcasting mode and by three layer separation of data Layer, Business Logic and user interface；Step 2, browser are used
Real-time progress is broadcast live to server terminal inquiry by web server in family end；Step 3, server terminal is by real-time transmission data
Screen data, which are copied, with browser terminal carries out analysis comparison；Step 4, server subtract frame through video/audio data and send and browser end
End.
Preferably, as in step 2 browser client playing progress rate inquiry include the following steps：
Screen is copied in a, browser client end to the picture played in real time in the page；
B, and by it is described copy screen data packet group in addition copy screen the time be sent in server terminal；
C, data server is compared data are received with history video frame by frame in server terminal, according to data transmission terminal object
Reason address determines its playing progress rate.
Preferably, include following sub-step as subtracted frame transmission in step 4：
1), according to data server response and reduced time, data transmission period, subtract frame video production duration, browsing
Device progression time is poor, determines that server terminal making subtracts frame video length；
2), subtract frame video according to mode in step 1) and at least continuously transmit three inferior to browser end according to reproduction time section
End.
Real-time progress monitoring system is broadcast live based on BS structural networks, the browser terminal passes through a web server and clothes
Be engaged in device terminal carry out data interaction, the server terminal includes data server, the data server include database and
Comparison unit, the databases contain history played data and subtract frame data package.
Preferably, the browser terminal copies screen data by one and is transferred to server terminal, the number by web server
Include data comparison unit according to server, is compared with history played data screen verse will be copied.
Preferably, the drop frame data package includes primary subtracting frame data package, secondary subtracting frame data package and subtract three times
Frame data package, wherein the primary frame data package that subtracts is the when subtractive frame data that browser terminal receives broadcasting for the first time,
The secondary frame data package that subtracts is that the primary frame data package that subtracts is formed by video time-base when being watched on browser terminal, is subtracted three times
Frame data package is the secondary broadcasting time difference subtracted caused by frame data package viewing time.
The invention has the advantages that：
The present invention by be broadcast live watch when caused viewing delay eat the time and carry out drop frame viewing, and then do not influencing
The integrality of live streaming viewer's viewing keeps up with live streaming progress, is carried out copying the real-time viewing progress of screen transmission and clothes according to browser terminal
The data of business device terminal send history and are compared, and the inquiry time delay time, comparison is accurate, and server terminal is according to browser terminal
Physical address, sent to browser terminal and at least three subtract frame data package, browser terminal in a manner of F.F. into
Row plays the delay time difference of a period of time reduction network direct broadcasting.
Certainly, it implements any of the products of the present invention and does not necessarily require achieving all the advantages described above at the same time.
