Abstract

Since the core of a screen sharing is usually the applications instead of the actual screen of the presenter, this invention transfers logs, which is smaller in size than graphics, between the presenter and recipients for the “reenactment” of the application behaviors. The applications on the recipients’ side receive the logs and then “reenact” the behaviors of the applications on the presenter’s side. Therefore the recipients can see the key application behaviors of the presenter in real-time and it doesn’t require very high network speed.

A method of sharing screens under limited internet condition

With the development of IT environments in recent years , there are increasing needs to hold online meetings with others working in different places. In such online meetings, it’s essential to share the screen among all participants, but we are often annoyed by the lags between a screen operated by the speaker and a screen viewed by each participant. When the speaker has already moved his or her speech to the next part, the listeners’ screens are still stuck with the previous content. This delay of data transmission affects the interaction between the speaker and listeners, kills their time and patience, and also hinders the listener’s understanding. In such annoying cases, we usually have no choice but sit and wait. Obviously, the major culprit of this delayed sharing is the slow network speed. One can easily think of the solution of improving the network speed to avoid the delay of data transmission. This proposal works, but due to the budget limit, it’s not feasible for large companies to spend lots of money to improve the broadband speed in the short term . So in the condition that the network speed can’t be improved in the short term, is there a solution to change the way of data transmission to speed up screen sharing? Since the core of a screen sharing is usually the applications instead of the actual screen of the presenter, this invention transfers logs, which is smaller in size than graphics, between the presenter and recipients for the “reenactment” of the application behaviors. The applications on the recipients’ side receive the logs and then “reenact” the behaviors of the applications on the presenter’s side. Therefore the recipients can see the key application behaviors of the presenter in real-time and it doesn’t require very high network speed.

1. The inviter sends a synchronization invitation to all the invitees. The invitation message includes the files that need to share and the apps that need synchronization.

2. The invitees accept the invitation, and then all related apps start up automatically. 3. Once the sharing starts, all the inviter ‘s motions are captured and be generated to the log files . 4. The inviter 's logs are instantly transferred to all the invitees’ systems. ...
