Proceedings ArticleDOI
Multi-codec DASH dataset
TL;DR: In this paper, the authors proposed a multi-codec DASH dataset comprising AVC, HEVC, VP9, and AV1 in order to enable interoperability testing and streaming experiments for the efficient usage of these codecs under various conditions.
Proceedings ArticleDOI
A test-bed for quality of multimedia experience evaluation of Sensory Effects
TL;DR: A prototype test-bed for triggering sensory effects like light, wind, or vibration when presenting audiovisual resources, e.g., a video, to users is presented and initial experiments and results on determining the color of light effects from the video content are reported.
Proceedings ArticleDOI
Dynamic Adaptive Point Cloud Streaming
TL;DR: The concept of dynamic adaptive streaming over HTTP (DASH) towards DASH-PC, a dynamic adaptive bandwidth-efficient and view-aware point cloud streaming system, is extended and multiple thinning approaches to spatially sub-sample point clouds in the 3D space are proposed.

TL;DR: This paper provides a detailed overview of the crowdsourcing frameworks and evaluates them to aid researchers in the field of QoE assessment in the selection of frameworks and crowdsourcing platforms that are adequate for their experiments.
Proceedings ArticleDOI
Towards peer-assisted dynamic adaptive streaming over HTTP
TL;DR: This paper presents the peer-assisted Dynamic Adaptive Streaming over HTTP (pDASH) proposal as well as an evaluation based on the DASH simulation environment in comparison to conventional approaches, i.e., non-peer-assisted DASH.
