A system and method distributes data and power in a robust manner for a large scale LED display. Master modules of the display are capable of receiving a data stream on any one of four data ports. The master modules extract the data for its module and an associated group of slave modules from a data stream received on one port and send the received data stream to three other master modules via the other three data ports. Unregulated D. C. power is distributed from one or more power hubs to the master modules which in turn distribute regulated D. C. power to their associated slave modules.

L'invention concerne un système et un procédé qui distribue des données et de la puissance de manière robuste pour un affichage DEL à grande échelle. Les modules maîtres de l'affichage peuvent recevoir un flux de données sur l'un des quatre ports de données. Les modules maîtres extraient les données pour son module et un groupe associé de modules asservis à partir d'un flux de données reçu sur un port et envoient le flux de données reçu à trois autres modules maîtres par le biais des trois autres ports de données. Une alimentation à courant continu non régulée est distribuée d'un ou plusieurs concentrateurs de puissance aux modules maîtres qui distribuent à leur tour l'alimentation à courant continu régulée à leurs modules asservis associés.
