ACMMM'19 Tutorial: A Journey towards Fully Immersive Media Access

ACM Multimedia 2019
October 21-25, 2019, Nice, France

Note: exact date/time slot of this tutorial will be provided at a later stage


Christian Timmerer, Alpen-Adria-Universit├Ąt Klagenfurt & Bitmovin, Inc.
Ali C. Begen, Ozyegin University and Networked Media


Universal media access as proposed in the late 90s, early 2000 is now reality. Thus, we can generate, distribute, share, and consume any media content, anywhere, anytime, and with/on any device. A major technical breakthrough was the adaptive streaming over HTTP resulting in the standardization of MPEG-DASH, which is now successfully deployed in HTML5 environments thanks to corresponding media source extensions (MSE). The next big thing in adaptive media streaming is virtual reality applications and, specifically, omnidirectional (360°) media streaming, which is currently built on top of the existing adaptive streaming ecosystems. This tutorial provides a detailed overview of adaptive streaming of both traditional and omnidirectional media within HTML5 environments. The tutorial focuses on the basic principles and paradigms for adaptive streaming – both traditional and omnidirectional media – as well as on already deployed content generation, distribution, and consumption workflows. Additionally, the tutorial provides insights into standards and emerging technologies in the adaptive streaming space. Finally, the tutorial includes the latest approaches for immersive media streaming enabling 6DoF DASH through Point Cloud Compression (PCC) and concludes with open research issues and industry efforts in this domain.

Keywords: Omnidirectional media, HTTP adaptive streaming, over-the-top video, 360 video, virtual reality, immersive media access.

Learning Objectives

This tutorial consists of two main parts. In the first part, we provide a detailed overview of the HTML5 standard and show how it can be used for adaptive streaming deployments. In particular, we focus on the HTML5 video, media extensions, and multi-bitrate encoding, encapsulation and encryption workflows, and survey well-established streaming solutions. Furthermore, we present experiences from the existing deployments and the relevant de jure and de facto standards (DASH, HLS, CMAF) in this space. In the second part, we focus on omnidirectional (360) media from creation to consumption as well as first thoughts on dynamic adaptive point cloud streaming. We survey means for the acquisition, projection, coding and packaging of omnidirectional media as well as delivery, decoding and rendering methods. Emerging standards and industry practices are covered as well (OMAF, VR-IF). Both parts present some of the current research trends, open issues that need further exploration and investigation, and various efforts that are underway in the streaming industry.
Upon attending this tutorial, the participants will have an overview and understanding of the following topics:
  • Principles of HTTP adaptive streaming for the Web/HTML5
  • Principles of omnidirectional (360-degree) media delivery
  • Content generation, distribution and consumption workflows for traditional and omnidirectional media
  • Standards and emerging technologies in the adaptive streaming space
  • Current and future research on traditional and omnidirectional media delivery, specifically enabling 6DoF adaptive streaming through point cloud compression
ACM Multimedia attracts attendees that are quite knowledgeable in specific areas. However, not all are experts across multiple disciplines (such as the subject matter here) and only few are familiar with what is happening in the field and standards. Thus, we believe the proposed tutorial will be of interest to this year’s attendees as much as it did in the past.

DASH-IF Interoperability Documents for Community Review

Community Review documents are published on the DASH-IF website in order to get feedback from the industry on tools and features that are documented for improved interoperability. For each of the documents, comments may be submitted on the technologies itself, on specific features, etc. These documents are only published temporarily for community review and will be replaced by a full version after the commenting period has closed and the comments have been addressed.


The change request against IOP v4.3 for Community Review is accessible here. This change provides a new clause for live services that addresses specification updates as well as implementation guidelines to support Low-Latency DASH services addressing the requirements above. Community review is open until July 31st, 2019. Addition to IOP is expected by Q3/2019. Comments may be submitted through the github or public bugtracker.


The new draft specification is accessible here and a pdf version. This document specifies protocol interfaces for live ingest/egress of media content. It can be used between live ABR encoders, streaming origins, packagers and content delivery networks. It features support for redundant workflows with failover support and timed metadata. Community review is open until July 31st, 2019. Publication is expected by Q3/2019. Comments may be submitted through the github or public bugtracker.

IEEE JSAC: Multimedia Economics for Future Networks: Theory, Methods, and Applications

Guest Editorial
Multimedia Economics for Future Networks: Theory, Methods, and Applications

Authors: Wen Ji, Zhu Li, H. Vincent Poor, Christian Timmerer, and Wenwu Zhu

Abstract: With the growing integration of telecommunication networks, Internet of Things (IoT), and 5G networks, there is a tremendous demand for multimedia services over heterogeneous networks. According to recent survey reports, mobile video traffic accounted for 60 percent of total mobile data traffic in 2016, and it will reach up to 78 percent by the end of 2021. Users’ daily lives are inundated with multimedia services, such as online video streaming (e.g., YouTube and Netflix), social networks (e.g., Facebook, Instagram, and Twitter), IoT and machine generated video (e.g, surveillance cameras), and multimedia service providers (e.g., Over-the-Top (OTT) services). Multimedia data is thus becoming the dominant traffic in the near future for both wired and wireless networks.
