The latest increase in multi-view video solutions, including those for telepresence, commercial conferencing, remote collaboration, etc. requires support for the high-quality delivery of large amounts of content data. Meanwhile, the extensive proliferation of wireless network access technology and multiple network interfaces on modern devices prompt the network transmission performance over various access networks. Diverse multipath-based multi-view streaming and adaptive delivery solutions were proposed, but they do not enable differentiation between streams. This paper proposes MVP-DASH, a priority-aware adaptive multi-view video streaming scheme based on the MPEG-DASH framework. MVP-DASH enables improved visual quality for high-priority streams, while maintaining acceptable quality levels for low-priority streams, primarily when delivered over a dynamic network environment. The experimental evaluation of the MVP-DASH demonstrates the effectiveness of the proposal in terms of achieving higher video quality and fewer video quality switches in comparison with alternative approaches.
