Abstract
Primary and secondary servers are coupled together for furnishing a backed-up video streaming function for outputting a series of video content presentations to a user group. The primary server functions as the primary provider of the video files and the secondary server is arranged to operate as a “hot stand-by” to back-up the primary server. In the event the primary server is disabled, the secondary server takes over for the primary server in furnishing video content in accordance with a common playlist. When the secondary server goes down for any reason, the illustrated methodology effectively re-synchronizes the video content and the video stream of the secondary server with that of the primary server such that the secondary server is enabled to resume the back-up function without interruption of the video file streaming process being carried on by the primary server. Various program routines and sample screen displays are illustrated in an exemplary embodiment of the back-up dual server video streaming system and methodology.
