Keep better engaged with content and each other
The ZEGOCLOUD's whiteboard SDK is supported on major platforms such as Android, iOS, and Web, and it can be quickly integrated with a few lines of code.
Whiteboard features real-time voice and video
ZEGOCLOUD combines the self-developed audio and video technology with whiteboard to synchronize audio and video streams with whiteboard editing by carrying timestamps in audio and video streams and whiteboard file signaling when publishing and by aligning timestamps in both streams when playing.
Real-time multi-user collaboration
ZEGOCLOUD's self-developed intelligent algorithm can accurately determine when multiple users are online in real time to ensure the orderly multi-user interaction and realize the simultaneous collaboration of 100 users.
Optimize memory resources
Simplify signaling and protocols and optimize signaling services to reduce data generated during whiteboard file synchronization and caching, reducing bandwidth and memory usage.
Offer superior file quality
Deliver the original content of the file (including font and layout) perfectly while preserving the clarity even after scaling the file.
Excellent file loading and rendering
With the powerful self-developed rendering engine that encapsulates the components used to browse files on all platforms to process and zoom large files and special files.
Provide basic and advanced whiteboard tools such as multiple brushes, erasers, undo/redo, selections, text formatting, laser pointer, and more.
Display the whole input motions in real-time instead of displaying the final output, making the delivered content more reliable.
Support showing the every detail tips of the brushes, making the drawing smooth and more realistic.
Support tracking the host's sights, synchronize the screen vision of the host to the viewers, focus the attention and improve the concentration.
Provides high-quality voice and video recordings for online classes or conference scenarios. Users can replay recordings for review at their convenience.
Support static and dynamic document conversion. Convert multi-format files to the formats which can be presented on the whiteboard while preserving the animation effects, audio, and video in the original files.
Supports page turning, scrolling, zooming in and out, annotating files, displaying thumbnails of files, and obtaining remarks.
Support the H5 (mobile web app or page that can be shared easily on chat applications) teching materials to steadily present vivid animation effects and load rich audio and video resources, enable teachers to offer interesting courses, increase student engagement.
Data is transmitted through signaling channels and files are rendered vectorally, ensuring high-definition presentation of files without strongly relying on bandwidth and performance, preventing file data from being lost.
