June 24–25, 2025 – Berlin

Daniel Silhavy

Scientist and Project Manager

Fraunhofer FOKUS

Daniel Silhavy is a scientist and project manager at the business unit Future Applications and Media (FAME) of the Fraunhofer Institute for Open Communication Systems (FOKUS). He received his Master’s degree with the completion of his thesis “Ad Insertion in MPEG-DASH” at Fraunhofer Institute for Open Communication Systems (FOKUS) in 201. Daniel is the lead developer of the dash.js project and the development coordinator for the 5G-MAG Reference Tools.

His main area of expertise includes adaptive bitrate (ABR) streaming focusing on MPEG-DASH, Digital Rights Management (DRM), 5G media streaming and video-encoding. Daniel is actively contributing to standardization work done in DASH-IF and CTA-WAVE. Moreover, Daniel is giving lectures at the Technical University of Berlin and is supervising Bachelor and Master theses. As part of his work in dash.js and the 5G-MAG Reference Tools, Daniel has developed in-depth knowledge in the field of media streaming and related specifications (ISO,3GPP,DVB,DASH-IF) and technologies, C++ programming, as well as web-based technologies and APIs such as HTML, JavaScript, node.js, MSE and EME.

Daniel has published various technical papers covering topics around ABR media delivery and streaming analytics.

The second part of the tutorial focuses on advances in low-latency streaming delivery, with particular emphasis on Low Latency Low Delay (L3D) DASH and Media over QUIC. It introduces the underlying principles, architectural considerations, and practical implications of both adaptive streaming technologies with emerging transport protocols designed for improved latency and efficiency.

Whenever possible, these concepts are illustrated through short live demonstrations, with a particular focus on playback using the DASH reference player dash.js and the FAMIUM MoQ player.

Topics include:

Low Latency Low Delay (L3D) DASH: concepts, mechanisms, and implementation considerations

Media over QUIC: architecture, transport features, and integration with adaptive streaming

Web Media APIs and protocols: Media Source Extensions (MSE), Web Transport API, QUIC

Live demonstrations: dash.js and FAMIUM MoQ
