Systems, devices and methods are provided to arbitrate network bandwidth that is shared between multiple video players executing concurrently on one or more client platforms that each have at least one video data stream supplied over a data network. An amount of bandwidth available from the data network is determined. An arbitration module calculates whether the selected video players can sustain a video playback quality above a pre-defined threshold using the determined amount of bandwidth available, and a modify playback message is sent to at least one video player when the video playback quality is not sustainable. Various implementations could prioritize bandwidth based upon the content presented so that high-bandwidth scenes (e.g., action sequences) receive more bandwidth than more static scenes.
