SYSTEM AND METHOD FOR FACILITATING VIDEO REDUNDANCY

摘要

A redundant display system includes a communication network, display devices, first and second display nodes, a control node, a monitoring node, and a system node. Display devices each include first and second display inputs. First display nodes include first display outputs, each connected to a first display input to display digital content on display devices and can be assigned the role of main or redundant display node. Second display nodes include second display outputs, each connected to a second display input to display digital content on display devices and can be assigned the role of main or redundant display node. The control node sends digital content to the display nodes. The monitoring node collects operational information of the display nodes and generates alerts if the operational information indicates a failure. The system node receives alerts from the monitoring node and reassigns roles of the display nodes based on the alerts.

1. A redundant display system comprising:
a communication network; a plurality of display devices in communication with the communication network, each display device including a first display input and a second display input; a first display node in communication with the communication network and arranged to display digital content on the plurality of display devices, the first display node including a plurality of first display outputs, each of which is connected to the first display input of one of the plurality of display devices, where the first display node can be assigned the role of main display node or redundant display node; a second display node in communication with the communication network and arranged to display digital content on the plurality of display devices, the second display node including a plurality of second display outputs, each of which is connected to the second display input of one of the plurality of display devices, where the second display node can be assigned the role of main display node or redundant display node; a control node in communication with the communication network and configured to send the digital content to the first display node and the second display node; a monitoring node configured to collect operational information of the first display node and second display node and generate alert information if the operational information indicates the first display node or second display node has failed; and a system node configured to receive alert information from the monitoring node and reassign the role of the first display node and second display node based on the alert information.
