Ddisp
Ddisp, short for Distributed Display Protocol, is an open standard designed to coordinate framebuffer updates across multiple display nodes in real-time visualization setups. It defines a compact, extensible message model that enables tile assignment, metadata exchange, and synchronized refresh across video walls, multi-projector arrays, and edge-rendering clusters. The protocol emphasizes low latency, deterministic timing, and scalability for high-resolution compositions.
Ddisp originated in 2016 as a collaboration among university labs and industry partners seeking a lightweight
Core ideas include a small set of message types (TILE_ASSIGN, UPDATE, SYNC, HEARTBEAT, SHUTDOWN) and a frame-oriented
A typical deployment includes a central scheduler that assigns frames to tiles and a per-tile Ddisp client
Used in digital signage networks, control rooms, immersive environments, and research labs, Ddisp interoperates with OpenGL
