Picture sharing method and system

Abstract

The invention discloses a picture sharing method and system. The picture sharing method comprises the following steps: a master device performs handshake with a slave device when receiving a picture sharing request initiated by the slave device; when the master device performs handshake with the slave device successfully, the master device performs network coding on a picture signal to be shared,outputs a TS bare stream signal to the slave device, and plays the picture to be shared; and the slave device receives and decodes the TS bare stream signal, and synchronously displays the current picture to be shared. Thus, the picture information of the master device can be displayed synchronously on other slave devices without delay and jamming; and a private protocol is used in network transmission, therefore, network security and picture transfer efficiency are ensured.

Description

technical field [0001] The present invention relates to the technical field of display all-in-one machines, in particular to a screen sharing method and system. Background technique [0002] The conference tablet integrates computer, projector, electronic whiteboard, TV, advertising machine, and audio, and has functions such as writing, annotation, synchronous interaction, multimedia, and remote video conferencing, and integrates high-definition display, human-computer interaction, multimedia information processing, and network transmission. And many other technologies, often used in government and enterprise conference rooms, media studios, education and training institutions and other places. At the same time, the conference panel has strong scalability and can be compatible with a variety of USB devices, network cards, wireless keyboards, and mice. One machine can meet various needs, and most of them have Windows and Andriod intelligent dual systems. The operation is simp...

Problems solved by technology

[0003] Based on these existing technologies and usage scenarios, with the development of science and technology and the continuous improvement of display technology, when a meeting is held in a particularly large venue, multiple conference panels are generally placed, and a larger conference panel is used in the middle of the venue. Smaller conference panels are placed in other places where they are needed, but the current problem is that the middle conference panel cannot be linked to other conference panels during the PPT demonstration operation, and a special person is required to control it, which is very inconvenient to use. The experience is very bad, especially when using a whiteboard to write, there is no way to synchronize it to other conference tablets. As a result, in large meetings, especially when group discussions are required, there is no way to replace ordinary whiteboards
