Upcoming IRT Seminar on Adaptive Streaming and MPEG-DASH

​A timely event related to the exploding world of end-user devices and services, an upcoming international intensive seminar offered by IRT will focus on Adaptive Streaming and MPEG-Dash for cross-device distribution of content over the open internet to PCs, mobile devices and via HbbTV.

Transcoding services for on-demand content now support the Common Media Application Format (CMAF), a specification that defines a common file format for segmented media delivery. This single type of file container is used for delivering media assets to a wide range of devices, from smart TVs, laptops and phones to smart watches. What  is  the  Common  Media  Application  Format  (CMAF) compared  to  the  ISO  Base  Media  Fileformat  (ISOBMFF)  and  how  could  DASH versus  HLS  benefit? Can the Common Media Application Format (CMAF) satisfy the need of a combined delivery via HLS and DASH to HbbTV, PCs and mobiles?

IRT DASH Seminar

This international seminar, offered in English, will be held on 10-11 July 2018 at the IRT in Munich, places are still available, register here

This seminar will provide an overview of the current state of adaptive video streaming, identifying problems and showing the results of IRT´s streaming tests for PC, HbbTV and mobile devices.

Practical examples for interoperable and cross-device streaming workflows over the CDN will be presented using open source tools and professional products from different manufacturers.

A number of media players for web browsers will be discussed in the context of whether MPEG-DASH or CMAF will be able to satisfy the needs for an adaptive, scalable cross-platform media streaming solution for future OTT services.

Held twice a year, the July seminar will ​provide an in-depth look at the state of the art of streaming today. The agenda includes:
​- video codecs, audience and devices, with a lab session on transcoding DVB recordings with ffmpeg in SD for HbbTV and tablets

​- the history of multimedia transport, looking at progressive download vs adaptive streaming, Apple HLS, Adobe HDS and MPEG-DASH, and the end of Adobe Flash, including an illustrative review via the playback of IRT reference clips.

​- MPEG DASH and CMAF standardisation, going in-depth into the scope, client architecture, profiles, container structures, segmentation, redundancy and tiled streaming.

​- constraints and capabilities in HbbTV and PC - taking in a thorough technical view of live events, Ultra HD, HDR, common encryption and DRM capabilities and subtitling for PC, HbbTV and mobile

- Content Delive​ry Network (CDN) workflows, encoders and Quality of Experience (QoE) - this session will look at the encoding profiles and pre-processing workflows for web distribution at German public service broadcaster ARD. It will also compare the YouTube and Netflix encoding profiles, and look at live pass-through for DASH and CMAF, repackaging and transcoding with Akamai all the way through to bitrate adaption algorithms, segment duration and low latency streaming.

The seminar will finish with a session on Quality of Service (QoS) metrics for live events and catch-up TV.
