HTTP Adaptive Streaming – Quo Vadis? (2024)

Telecom Seminar Series at TII, Jun 27, 2024, 04:00 PM Dubai

Abstract: Video traffic on the Internet is constantly growing; networked multimedia applications consume a predominant share of the available Internet bandwidth. A major technical breakthrough and enabler in multimedia systems research and of industrial networked multimedia services certainly was the HTTP Adaptive Streaming (HAS) technique. This resulted in the standardization of MPEG Dynamic Adaptive Streaming over HTTP (MPEG-DASH) which, together with HTTP Live Streaming (HLS), is widely used for multimedia delivery in today’s networks. Existing challenges in multimedia systems research deal with the trade-off between (i) the ever-increasing content complexity, (ii) various requirements with respect to time (most importantly, latency), and (iii) quality of experience (QoE). Optimizing towards one aspect usually negatively impacts at least one of the other two aspects if not both. This situation sets the stage for our research work in the ATHENA Christian Doppler (CD) Laboratory (Adaptive Streaming over HTTP and Emerging Networked Multimedia Services; https://athena.itec.aau.at/), jointly funded by public sources and industry. In this talk, we will present selected novel approaches and research results of the first year of the ATHENA CD Lab’s operation. We will highlight HAS-related research on (i) multimedia content provisioning (machine learning for video encoding); (ii) multimedia content delivery (support of edge processing and virtualized network functions for video networking); (iii) multimedia content consumption and end-to-end aspects (player-triggered segment retransmissions to improve video playout quality); and (iv) novel QoE investigations (adaptive point cloud streaming). We will also put the work into the context of international multimedia systems research.

Video Developer Report 2019

... and Bitmovin did it again; published the 2019 Video Developer Report last week. I've briefly reported about it last year here. Interestingly, this year 542 people from 108 countries participated (vs. 456 from over 67 countries last year).

The biggest challenges seem to be latency (54%) and playback on all devices (41%). Other challenges (>20%) are related to DRM, CDN, user engagement with video, and ads in general.

Last year I've also shared the codec usage and it's probably interesting to compare these numbers with this year's results as shown below. Interestingly, the numbers (for 'planning to implement') are a bit lower compared to last year which could be explained by a more conservative approach from developers or simply by the fact that more people responded to the survey with a greater diversity in terms of different countries.

Current Video Codec Usage and Plans to Implement in next 12 Months.
The actual video codec usage compares to last year's report as follows: AVC (-1), HEVC (+1), VP9 (+/- 0), AV1 (+1).

Another interesting aspect is the usage of streaming formats and plans to implement them within the next 12 months as shown below. Comparing with last year's report (available here), we can observe the following major changes: HLS (-3), MPEG-DASH (-3), RTMP (-2), Smooth Streaming (+2), Progressive Streaming (-1), MPEG-CMAF (+2), HDS (-4).

Current Streaming Formats and Plans to Implement in next 12 Months.

In general, one can observe that the adoption of new formats are happening at a slower pace than expected and I am wondering what this means for the new video coding formats coming up like VVC et al. (note: these are results from a public survey with different participants compared to last years which need to be taken into account when comparing results over years).

For more details, the full report can be downloaded for free from here.

Adaptive Streaming of Traditional and Omnidirectional Media


This tutorial will be given at the following events:

Abstract

This tutorial consists of three 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. 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. The last part presents some of the current research trends, open issues that need further exploration and investigation, and various efforts that are underway in the streaming industry.

VideoNext: Design, Quality and Deployment of Adaptive Video Streaming


The workshop co-located with CoNEXT 2014
December 2, 2014
Sydney, Australia

Submission deadline changed: August 29, 2014 (no further extensions)

Call for Papers

As we continue to develop our ability to generate, process, and display video at increasingly higher quality, we confront the challenge of streaming the same video to the end user. Device heterogeneity in terms of size and processing capabilities combined with the lack of timing guarantees of packet switching networks is forcing the industry to adopt streaming solutions capable of dynamically adapting the video quality in response to resource variability in the end-to-end transport chain. For example, many vendors and providers are already trialing their own proprietary adaptive video streaming platforms while MPEG has recently ratified a standard, called Dynamic Adaptive Streaming over HTTP (DASH), to facilitate widespread deployment of such technology. However, how to best adapt the video to ensure highest user quality of experience while consuming the minimum network resources poses many fundamental challenges, which is attracting the attention of researchers from both academia and industry. The goal of this workshop is to bring together researchers and developers working on all aspects of adaptive video streaming with special emphasis on innovative concepts backed up by experimental evidence.

Specific areas of interest include, but are not limited to:
  • New metrics for measuring user quality of experience (QoE) for adaptive video streaming
  • Solutions for improving streaming QoE for high-speed user mobility
  • Analysis, modelling, and experimentation of DASH
  • Exploitation of user contexts for improving efficiency of adaptive streaming
  • Big data analytics to assess viewer experience of adaptive video
  • Efficient and fair bandwidth sharing techniques for bottleneck links supporting multiple adaptive video streams
  • Network functions to assist and improve adaptive video streaming
  • Synchronization issues in adaptive video streaming (inter-media, inter-device/destination)
  • Methods for effective simulation or emulation of large scale adaptive video streaming platforms
  • Cloud-assisted adaptive video streaming including encoding, transcoding, and adaptation in general
  • Attack scenarios and solutions for adaptive video streaming
  • Energy-efficient adaptive streaming for resource-constraint mobile devices
  • Reproducible research in adaptive video streaming: datasets, evaluation methods, benchmarking, standardization efforts, open source tools
  • Novel use cases and applications in the area of adaptive video streaming

The workshop is considered an integral part of the CoNEXT 2014 conference. All workshop papers will be published in the same set of proceedings as the main conference, and available on the ACM Digital Library. Publication at this workshop is not intended to preclude later publication of an extended version of the paper. At least one author of each accepted papers is expected to present his/her paper at the workshop.

JSAC Special Issue: Adaptive Media Streaming

IEEE Journal on Selected Areas in Communications (JSAC)
Call for Papers
Special Issue on Adaptive Media Streaming
Submission Deadline: April 1 April 15, 2013 (***Happy Easter!***)
[ PDF ]
Publication, vol. 32, no. 4, April 2014: IEEEXplore

Recently, traditional TV services, Internet TV and mobile streaming services have started converging, and it is expected that this convergence trend will continue with other services. Additionally, new emerging multimedia services are being introduced. These developments in the multimedia arena mean that various content and services will be delivered over different networks, and the users expect to consume these services using those networks, depending on the availability and reach of the network at the time of consumption. This massive heterogeneity in terms of terminal/network capabilities and user expectations requires efficient solutions for the transport of modern media in an interoperable and universal fashion. In particular, in recent years, the Internet has become an important channel for the delivery of multimedia. The Hypertext Transfer Protocol (HTTP) is widely used on the Internet and it has also become a primary protocol for the delivery of multimedia content.

Additionally, standards developing organizations (SDOs) such as MPEG have developed various technologies for multimedia transport and encapsulation, e.g., MPEG2-TS (Transport Stream) and MPEG4 file format. These technologies have been widely adopted and are heavily deployed by various providers and in different applications and services, such as digital broadcasting, audio and video transport over the Internet and streaming to mobile phones, etc. At the same time, many other SDOs such as the IETF, IEEE, and 3GPP have provided various protocols to deliver multimedia content packetized or packaged by such MPEG transport technologies.

This special issue solicits novel contributions and breaking results on all aspects of Adaptive Streaming of Multimedia. The main objectives of this special issue are (but not limited to):
  • Efficient delivery of multimedia content in an adaptive, progressive download/streaming fashion (incl. over HTTP);
  • Support for streaming of live multimedia, to mobile users, low-capacity channels, bandwidth variations, as well as multipoint streaming over heterogeneous channels or paths;
  • Efficient and ease of use of existing content distribution infrastructure components such as CDNs, proxies, caches, NATs and firewalls;
  • Efficient content generation (encoding) techniques for content delivery (e.g., segmentation);
  • Detailed performance analyses of deployed standard technologies or that uncover and rectify major problems in the behavior of such technologies;
  • Measurement techniques for collecting consumption data (both application and transport-level performance metrics, viewer behavior, etc.) in content delivery;
  • The effects of adaptation techniques on the end-user quality of experience;
  • Viewer experiences from large-scale experiments and events (such as Olympics, World Cup, etc.).
