Abstract
The invention provides a method for realizing screen projection from a single PC screen to multiple different device screens. The method comprises the following steps of (1) deploying screen projection software on a source terminal device to realize screen audio-video data acquisition and reception of a terminal, and sending audio-video data by using an RTSP protocol through H264 standard coding compression; (2) establishing local area network communication between the source terminal device and a display terminal device; (3) providing a display operation interface by the screen projection software, and displaying a searched display terminal device list in a local area network, wherein a user can check a plurality of display terminal devices for output and display; and (4) deploying display software on the display terminal devices to realize search response to the source terminal device, and decoding, displaying and outputting the received audio-video data subjected to the H264 standard coding compression. According to the method, the purpose of projecting screen audios and videos of a terminal to a plurality of terminals for display without a forwarding server in a wireless screen projection application at present is achieved.
Description
Technical field
The present invention relates to a kind of realize the method that single PC screen throws screen to multiple distinct device screens.
Background technology
Existing technical scheme screen can pass through wire body or wireless mode one-to-many when throwing screen, but cannot realize wirelessly throwing
One-to-many in screen, screen throw multiple screens be accomplished by wired, and by build environment affected very big, transmission range,
Screen way is all very limited.
Content of the invention
Present invention proposition is a kind of to realize the method that single PC screen throws screen to multiple distinct device screens, solves current nothing
Line is thrown in screen application, and in the case of not having forwarding server, the screen audio frequency and video of a terminal can not be thrown into multiple terminals and show
The problem (because the data that the source terminal network interface card same time can send is limited, the network bandwidth is limited) shown, a whether screen
Curtain throws one, or multiple distinct device screens thrown by a screen, all can achieve wireless throwing screen.
The present invention to realize particular by technical scheme below：
A kind of realize single PC screen to multiple distinct device screens throw screen method, comprise the following steps：
(1) in source terminal equipment, screen software is thrown in deployment, realizes to the collection of terminal screen audio, video data and accepts；And lead to
Cross the compression of H264 standard code, send audio, video data using RTSP agreement；
(2) set up local area network communication between source terminal equipment and display terminal；
(3) throwing screen software provides operation display interface, by the display terminal's list display in the LAN searching,
User can choose multiple display terminals output display；
(4) deployment display software in display terminal, realizes the search response to source terminal equipment, by receive
Audio, video data decoding display output through the compression of H264 standard code.
Preferably, in source terminal, after user has chosen display terminal, a key is clicked on and is thrown screen, throws screen software according to source
The IP address of terminal unit determines a multicast address, and sends audio, video data to this multicast address.
Preferably, also send broadcast messages when clicking on and throwing screen to display terminal, show software receipt to after broadcast messages,
Parsing message authentication is collected the multicast group address of audio, video data and is added to this multicast group, and is regarded according to RTSP agreement acquisition sound
Frequency evidence, after display terminal receives audio, video data, decodes parsing audio frequency and video output using H264 standard, image is exported
Display, by audio output to sound card.
What the present invention produced has the beneficial effect that：Sharing of screen more facilitates and hommization, has not only broken away from wire body constraint,
Also greatly extend the spatial impression that screen is shared, do not affect image quality and tonequality simultaneously.
Specific embodiment
Technical scheme is clearly and completely described it is clear that being retouched below in conjunction with the embodiment of the present invention
The embodiment stated is only a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, this
The every other embodiment that field those of ordinary skill is obtained under the premise of not making creative work, broadly falls into the present invention
The scope of protection.
A kind of realize single PC screen to multiple distinct device screens throw screen method, comprise the following steps：
(1) in source terminal equipment, screen software is thrown in deployment, realizes to the collection of terminal screen audio, video data and accepts；And lead to
Cross the compression of H264 standard code, send audio, video data using RTSP agreement；
(2) set up local area network communication between source terminal equipment and display terminal；
(3) throwing screen software provides operation display interface, by the display terminal's list display in the LAN searching,
User can choose multiple display terminals output display；
(4) deployment display software in display terminal, realizes the search response to source terminal equipment, by receive
Audio, video data decoding display output through the compression of H264 standard code.
In source terminal, after user has chosen display terminal, a key is clicked on and is thrown screen, throws screen software according to source terminal equipment
IP address determine a multicast address, and to this multicast address send audio, video data.Also send program request when clicking on and throwing screen
Message, to display terminal, shows software receipt to after broadcast messages, and parsing message authentication collects the multicast group ground of audio, video data
Location is simultaneously added to this multicast group, and obtains audio, video data according to RTSP agreement, after display terminal receives audio, video data,
Decode parsing audio frequency and video output using H264 standard, by image output display, by audio output to sound card.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all essences in the present invention
Within god and principle, any modification, equivalent substitution and improvement made etc., should be included within the scope of the present invention.
