1 Introduction

The ZEGO whiteboard service (ZegoWhiteboard) provides online whiteboards for real-time multi-user interactions and collaborations. Users in the same room can write and draw on the same whiteboard to collaborate and exchange ideas in real time. With a rich set of whiteboard tools, real-time stroke synchronization, and precise synchronization between whiteboard and real-time audio/video, ZegoWhiteboard takes the online whiteboard experience to the next level.

3 Advantages

3.1 Comprehensive platform coverage

Comprehensive coverage of major platforms and development frameworks, including iOS, Android, Windows, macOS, and Web.

3.2 A rich set of whiteboard tools

ZegoWhiteboard SDK provides a rich set of whiteboard tools, including paintbrush, laser pointer, text tool, shape tools (lines, rectangles, circles, ellipses), and eraser.

3.3 Precise synchronization between whiteboard and real-time audio/video

When users use a whiteboard in an audio/video call or live streaming session, the whiteboard content and real-time audio/video streams are delivered to all participants in precise synchronization, so users won't have any whiteboard-audio/video out-of-sync issues.

3.4 Advanced real-time collaboration algorithm

ZEGO has developed an intelligent multi-user real-time conflict resolution algorithm, which can support hundreds of people to interact and collaborate efficiently (drawing, editing, etc.) on the same whiteboard.

3.5 Network acceleration for international collaborations

ZEGO provides global network acceleration to support international collaborations, improving real-time communications and collaboration experience with reduced transmission latency and packet loss.
