Medical video streaming utilizing MPEG-DASH

This paper presents an analysis of medical video streaming based on the Dynamic Adaptive Streaming over HTTP (DASH) standard from the Moving Picture Experts Group (MPEG).We propose two adaptation approaches at the client and evaluate parameters of the Quality of Experience (QoE), i.e., the quality perceived by the users, by investigating the number and duration of re-buffering events, the added time in the playout, and the Peak Signal-to-Noise Ratio (PSNR) of the medical video frames. The results show that the selection of MPEG-DASH related parameters and the adaptation approach at the client result in improved quality of the medical video streaming. In the end, we discuss how the elaborated approaches and results could be utilized to facilitate and enhance telemedicine applications.
