  1. 1. WE MAKE YOUR VIDEOS FLOW Industry Leading Streaming Solutions DASH Reference Software and Conformance 2014 NAB Show DASH Talks NAB 14 April 8, Las Vegas, NV, USA Dipl.-Ing. Dr. Christian Timmerer CIO | bitmovin GmbH & Alpen-Adria-Universität Klagenfurt
  2. 2. Scope of Reference Software and Conformance • Conformance and reference software of MPEG-DASH serves three main purposes: – validation of the written specification; – clarification of the written specification; and – conformance testing for checking interoperability for the various applications against the reference software which aims to be compliant with ISO/IEC 23009 • ISO/IEC 23009-2: media presentation conformance, test vectors, DASH access engine reference software, sample software Scope 1
  3. 3. Components • Media presentation conformance – MPD validator: xlink, schema validation, add’l validation rules – Segment conformance: check ISOBMFF, M2TS against DASH specification – Dynamic service validator: dynamic updates of the MPD • DASH conformance sequences • DASH access client reference software – libdash: access to information contained in the MPD + schedule download of segments • Sample software – Sample player: utilizes libdash, GUI, manual adaptation logic – GPAC player: integrated player or embeddable DASH engine – MP4Box segmenter: create segments + MPD based on encoded content • Computing Now theme – Recent MPEG standards for future media ecosystems – Components 2
  4. 4. Cloud-based MPEG-DASH Transcoding and Streaming for Broadcast Scenarios • Using scalable & flexible cloud infrastructure • MPEG-DASH representations for mobile devices (320p) up to PC/TV (1080p) • MPEG-DASH playback on multiple devices using HTML5 & Flash clients • Live / Timeshift / OnDemand using the same MPEG- DASH content CLOUD-BASED TRANSCODING & STREAMING MPEG-DASH CLIENTS CUSTOMER PORTAL SHOWCASE  Live  Timeshift  Catchup using EPG Data Cloud-DASH 3
  5. 5. Conclusions • MPEG-DASH Reference Software and Conformance – Comprehensive toolset for conformance testing – Verification and clarification of the written specification • Complementary DASH-IF software tools – Reference client, sample players, sample segmenters and packagers, libraries, manifest and ISOBMFF validator ➪ Conclusions 4
