For video applications, tiled streaming is a popular way to deliver viewport dependent 360-degree video. Unfortunately, dynamic adaptation to network bandwidth fluctuations of such video streams is still a challenge. This paper proposes a method for managing in a controlled way the graceful quality degradation in DASH-based streaming systems to deliver omnidirectional video. The method is enabled by the signaling of tile priority maps in order to reduce the impact of graceful degradation on the users’ Quality of Experience (QoE). Simulation results show that this method allows degrading the system by over 10% of minor bandwidth usage during Viewport Dependent Streaming, without sacrificing the user QoE so much compared to the case that does not make use of this technique. Furthermore, the presented method improves flexibility from the service provider’s standpoint.
