Abstract
The invention discloses a kind of high efficiency smart mobile phones to throw screen method, includes the following steps：S1, it is established on mobile phone and throws screen expanding element and database, databases contain mobile phone code with reference to table, throw screen expanding element and acquire screen video stream；S2, screen expanding element inquiry mobile phone code is thrown, and is compared with reference to table with the mobile phone code in database, determine whether the type handset processes performance is up to standard；Whether S3, throwing screen expanding element are up to standard according to handset processes performance, h264 hard codeds or the soft codings of h264 are carried out to collected screen video stream；S4, throwing screen expanding element are detected network speed, adaptively adjust code check according to testing result；S5, TCP connection is established by throwing screen expanding element and the ends PC, the video after coding, which is streamed to the ends PC, is decoded broadcasting.It is in application, can adjust the coding mode and code check of video flowing automatically according to the process performance of mobile phone and current network conditions when mobile phone is thrown and shielded.
Description
Technical field
The present invention relates to mobile phones to throw screen treatment technology, and in particular to a kind of high efficiency smart mobile phone throwing screen method.
Background technology
In smart mobile phone function further powerful today, using the screen projection function of smart mobile phone, many users started by
Smart mobile phone application is in meeting office and long-distance education, but the screen projection function of existing smart mobile phone is in the coding for carrying out video flowing
Intelligent not enough when output, coding mode and code check are usually fixed, and according to the actual performance of mobile phone and cannot be worked as
Preceding network environment is adaptively adjusted.
Invention content
The present invention is in view of the deficienciess of the prior art, provide a kind of high efficiency smart mobile phone throwing screen method, in application, can
When mobile phone is thrown and shielded, to be done automatically to the coding mode and code check of video flowing according to the process performance of mobile phone and current network conditions
Go out adjustment.
The invention is realized by the following technical scheme：
A kind of high efficiency smart mobile phone throwing screen method, includes the following steps：
S1, it is established on mobile phone and throws screen expanding element and database, throw screen expanding element and database data docking, data
It is stored with mobile phone code in library with reference to table, and process performance type up to standard and process performance are distinguished not on mobile phone code reference table
Type up to standard throws screen expanding element and acquires screen video stream；
S2, screen expanding element access queries mobile phone code is thrown, and by the mobile phone in the mobile phone code inquired and database
Code is compared with reference to table, determines whether the type handset processes performance reaches standard；
S3, handset processes performance are up to standard, throw screen expanding element and carry out h264 hard codeds, hand to collected screen video stream
Machine process performance is not up to standard, throws screen expanding element and carries out the soft codings of h264 to collected screen video stream；
S4, throwing screen expanding element are detected network speed, adaptively adjust code check according to testing result；
S5, TCP connection is established by throwing screen expanding element and the ends PC, and the video after coding is streamed to the ends PC；
The end S6, PC is decoded broadcasting to the data received.
Preferably, the throwing screen expanding element and database are integrated into cell phone application.
Preferably, the mobile phone code includes the corresponding mobile phone marking code number of current market institute organic type with reference to table.
The present invention has the advantage that and advantageous effect：
1, a kind of high efficiency smart mobile phone of the present invention throws screen method, can be according to the process performance of mobile phone to the coding of video flowing
Mode carries out adaptability selection.
2, a kind of high efficiency smart mobile phone of the present invention throws screen method, can be according to mobile phone current network conditions to the code of video flowing
Rate is adaptively adjusted.
3, a kind of high efficiency smart mobile phone of the present invention throws screen method, and video flowing code efficiency is high, and efficiency of transmission is high.
