Problems solved by technology

[0002] At present, multi-screen synchronous interaction is mainly based on the IP network and adopts the method of refreshing the entire screen at regular intervals and then transmitting the screenshot to the remote end. Regardless of whether the screen has changed or not, the entire screen image is transmitted. This method consumes a lot of network resources and takes up A large amount of system memory and CPU usage in terminal devices
The IP network is a "best effort" network. It does not provide a QoS (Quality of Service) guarantee mechanism. When it is necessary to transmit multiple services such as video, audio, and data at the same time, it is limited by the network bandwidth and speed. , will lead to excessive delay, lagging, etc., and the effect of synchronous interaction is not ideal.

Embodiment 1

[0096] A remote interactive method of multi-screen synchronous display supporting QoS in this embodiment, such as figure 1 Shown, mainly realize through following technical scheme: comprise the following steps:

[0097] Step S100: establishing an interactive platform for synchronous display;

[0098] Step S200: sharing a file source data package for synchronous interaction;

[0099] Step IF110: The web server continuously searches whether there is a new access request or a new logout request, if so, jump to step IF210, and if not, continue to execute step S200;

[0100] Step IF210: After the access request or exit request is processed, determine the value of the total number of clients N in the interactive platform. N is a non-negative integer. If N=0, skip to step S600; if N=1, skip to step S500; N≥2, execute step S300;

[0101] Step S300: Enter the synchronous interaction interface;

[0102] Step S400: synchronous interaction;

[0103] Step IF120: The web server continu...

Embodiment 2

[0114] This embodiment includes the following steps:

[0115] Step S100: Client A sends an interaction request to the network server by virtue of the unique ID number in the interactive platform obtained after successful registration, establishes the interactive platform and waits for other users to join;

[0116] Step S200: A shared folder with a default file source is automatically generated in the interactive platform and stored in the data server. Client A uses the RTP / RTCP protocol to upload the file source package from the local storage module to the shared folder for other users download;

[0117] Step IF111: The network server receives access requests sent by client B, client C, client D, and client E in the same period of time, and jumps to step IF112;

[0118]Step IF112: The data server detects that a complete file source data package has been stored in the local storage modules of A client, B client, C client, and D client; E client is downloading the file source d...

Abstract

The invention discloses a remote interaction method of multi-screen synchronous display supporting QoS. The remote interaction method comprises steps of establishing an interaction platform of synchronous display; sharing file source data bags of synchronous interaction; entering a synchronous interaction interface; performing synchronous interaction; exiting the synchronous interaction interface; and canceling the interaction platform. According to the invention, the file source data bags are firstly shared to the interaction platform, so a user end should load the file source data bags containing larger data amount in advance, and then can enter the synchronous interaction interface to perform synchronous interaction with other user ends. During the synchronous interaction process, instruction information containing smaller data amount and file source update logs are mainly transported and interaction of multi-screen synchronous and precise procedures is achieved.
