Abstract:
Embodiments of the present invention are directed to computer systems and methods of re-synchronizing playback of a live media stream with execution of a stream of out-of-band commands, where the commands and media stream are transmitted through different network pathways. The systems and methods, at a multimedia player, retrieve a command manifest file from a publishing server or CDN and parse the location of the media stream from the file. The systems and methods load and buffer the media stream from the parsed location and start playback of the media stream. The systems and methods monitor current playback time of the live media stream. The systems and methods also poll the user-initiated commands appended to the command manifest file. The systems and methods determine whether to execute a user-initiated command of the polled user-initiated commands in a user interface of the multimedia player based on the monitored current playback time.
