Embodiment Construction
[0111] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0112] In the prior art, data is mainly transmitted between multiple terminals through the TCP / IP protocol to achieve sharing of electronic whiteboards. The TCP / IP protocol is easily affected by the state of the network, resulting in delays in the electronic whiteboard data received by the terminal, resulting in a poor sharing experience of the electronic whiteboard. In addition, if the Internet is attacked by insecurity, the electronic whiteboard sent by the terminal There is a risk of leakage of the data; and the display interface of the terminal cannot display other data (such as audio data, video data, etc.) when displaying the data shared by the electronic whiteboard.
[0113] In view of this, the present invention proposes a...

The invention relates to the technical field of video data processing, and provides an electronic whiteboard display content synchronization method, device and apparatus and a storage medium, and themethod comprises the steps: converting the display content of an electronic whiteboard into a display data in a process of sharing an electronic whiteboard with a second articulated naturality web terminal; packaging the display data into a first articulated naturality web protocol packet; adding a packet header to the first articulated naturality web protocol packet; and sending the first articulated naturality web protocol packet carrying the packet header to the second articulated naturality web terminal through an articulated naturality web transparent transmission channel between the first articulated naturality web protocol packet and the second articulated naturality web terminal. Therefore, the display content of the electronic whiteboard can be stably synchronized between the articulated naturality web terminals for video conferences or video calls.
Description
technical field [0001] The invention relates to the technical field of video data processing, in particular to a method, device, device and storage medium for synchronizing display content of an electronic whiteboard. Background technique [0002] At present, in electronic whiteboard sharing, the display content of the electronic whiteboard interface is mainly transmitted through the TCP / IP protocol. The data transmission speed is easily affected by the network status, resulting in delays in the display of electronic whiteboard strokes and pictures. [0003] The Internet of View is a real-time network that can realize real-time transmission of high-definition video across the entire network that cannot be realized by the Internet at present, and realize high-definition face-to-face video conferencing. Multiple terminals on the Internet can cooperate to operate the same electronic whiteboard, which provides convenience for users to work remotely and conduct distance education...
