Schedulers for MPEG-DASH compliant multi-view video over LTE

Abstract

Higher data rates offered by Long Term Evolution (LTE) networks, better displays, and core architectures on mobile devices, provide the technology for transmission of multiview video (MVV) services. The high bandwidth required could be somewhat alleviated through high efficiency video coding, but this does not guarantee that quality of service (QoS) thresholds are met. To help with the varying network conditions of cellular environments, adaptive bitrate (ABR) solutions in an Over-The-Top (OTT) fashion provide a possible solution. This paper focuses on the medium access control (MAC) scheduler for transmission of MVV content over an LTE network. MPEG-DASH's features are considered as the basis of the ABR solution. Simulation results show reduced packet losses and increased numbers in concurrent users, compared to a non-ABR solution. Moreover, to improve the video quality, each main view was prioritized through the Evolved Packet System (EPS) bearer to better protect this content and its decodability.
