Aviation Command Communication Technology Implementation Solution

Low-latency audio/video transmission: WebRTC technology is used to establish P2P audio/video calls and data channels, achieving ultra-low-latency transmission of audio/video streams and desktop streams, with video resolution supporting 1080P HD and end-to-end latency ≤300ms;

Cross-end real-time annotation: Canvas+Fabric.js front-end graphics libraries are integrated to enable bidirectional real-time annotation across endpoints, supporting multiple annotation tools such as arrows, box selection, brush, text, and highlight, with annotation trajectories and graphics synchronized in real time without latency;

One-click flight number association: Flight information is synchronized in real time with the FOC system, and dispatcher and crew information is automatically associated based on flight numbers, enabling one-click direct dialing for video calls. When a call is connected, the dispatch console side automatically pops up the real-time video image of the called party (dispatch extension/crew);

Local storage and retrieval: All audio/video streams, operation data, and annotation content are stored on the client's local server, using flight number + time as the unique retrieval key, supporting multi-condition combined retrieval, and achieving synchronized playback of audio/video, operations, and annotations during replay.
