Thesis : A Dynamic Adaptive HTTP Streaming Video Service for Google Android (HLS/DASH)
ABSTRACT OF LUCIANO ROMERO'S THESIS :
Adaptive streaming approaches overHypertext Transfer Protocol (HTTP), such as Apple’sHTTP Live streaming (HLS) andMicrosoft’s Live Smooth Streaming, have recently become very popular. This master’s thesis project developed and evaluated several media rate adaptation algorithms optimized for mobile networks with a client running on Google’s Android operating system. The deployed service supports HLS and the emerging ISO/IEC MPEG standard called Dynamic Adaptive Streaming over HTTP (MPEG-DASH).
This project has produced an implementation of HTTP-based adaptive streaming. This implementation follows the MPEG standard and enables robust and smooth playback of live video content via Google’s Android devices. Results of the experiments have shown that the proposed adaptation mechanisms efficiently utilize the available bandwidth of the network. A

DASH is the new Dynamic Adaptive Streaming over HTTP standard from MPEG. This patch adds the support for DASH in GStreamer, through the new bin elementDASHBIN.
More in detail, the patch adds 3 new elements to the gst-plugins-bad-0.10.23plugin package: 1) mpdcommon: an helper library to browse and manage the DASH MPD manifestfiles; 2) mpdparse: the mpdparse plugin, that detects and parses the MPD manifestfiles; 3) dashbin: the DASH client, implemented as a src bin;
A simple usage example is:gst-launch \dashbin location=http://example.com/dash_manifest.mpd \! qtdemux ! queue ! ffdec_h264 ! xvimagesink Via Nicolas Weil 
The MPEG-7 AudioVisual Description Profile (AVDP) has become a new ISO International Standard. The profile is specially designed for representing and exchanging metadata generated by automatic extraction tools, such as speech-to-text transcription engines and videoshot detection algorithms. 
Smooth Streaming has been a pivotal technology of the Microsoft Media Platform since its introduction in IIS Media Services 2.0 in 2009. And though it’s been commonly associated with Silverlight over the years, those familiar with Smooth Streaming architecture and the Smooth Streaming Media Element probably know that the relationship between Smooth Streaming and Silverlight was never an exclusive one. For starters, the Smooth Streaming Protocol Specification and the Protected Interoperable File Format (PIFF) Specification have been public for years. After all, at its heart Smooth Streaming is not much more than a combination of HTTP requests, XML and fMP4 parsing, download heuristics and video/audio decoding. It’s a fairly open, standards-based technology that has very few dependencies on the client platform. Via Nicolas Weil
In an impressive display of trade-show partnerships, Elemental Technologies has announced that thirteen partners were including Elemental’s video processing solutions for multi-screen content delivery in their booths this week at NAB.
This collaborative fest is a sign of the traction that Elemental has gained in several markets. At the end of 2011, Elemental touted the milestone of 100 enterprise customers acquired since it launched its professional product line in 2010. Among its marquee customers are Comcast, ESPN and HBO. The six-year-old Portland-based company said that its customer wins drove a 300 percent growth in revenue in 2011.
The NAB collaboration also reflects a diverse portfolio that includes streaming, transcoding, server, file-to-file, management and video compression products. Elemental sells into a range of markets, including service providers, broadcasters, programmers and premium brands. It positions its solutions within what it calls “the new media aftershock,” which relates to the large number of customized streams that content producers and distributors require in a multi-screen world.

The validator offers the possibility to validate DASH files. This can either be done via file upload, URL or direct input of the description. Furthermore, the validator checks not only schema compliance but also semantic compliance of a description as specified in the corresponding parts of the standard. Via Nicolas Weil 
The next-gen video compression technology shrinks video by 40 to 45 percent compared to today's prevailing H.264. But encoding H.265 video takes a long time right now.
Qualcomm, a San Diego-based chipmaker that's on the international standards group developing H.265, demonstrated a preliminary version of H.265 video on an Android tablet at the Mobile World Congress show here in Barcelona.

Destiny Media Technologies is pleased to provide an update on development of its second generation playerless streaming video solution, which will eliminate the need for publishers to maintain separate streaming hardware and various video formats to reach their audience.
Destiny has developed a single video file format that acts like any other web object, streaming directly from a web server and rendering directly by the browser without a player plug-in. The technology is working well across a wide number of computers and smart phones, including Mac, Windows, Android, iPhone, iPad, Blackberry and any other recent device that is standards compliant. Video playback is at twenty-four frames per second and at similar quality to competing offerings. The company is currently building out the prototype solution into a mass-market product. A soft launch of the commercial product for sale to select early customers is expected by April. Via Nicolas Weil

Video-processing solutions vendor Elemental Technologies is debuting a server aimed at cutting bandwidth and storage needed for multiscreen-video distribution, by packaging streams closer to end users. Using Elemental Stream, video can be sent over a CDN in a single encoded video format and then specific digital rights management and adaptive bit-rate formats can be applied at the time of distribution. The company expects the product to be generally available in the third quarter of 2012.
The new server supports closed captioning and subtitle conversion, SCTE-35 advertising triggers and can associate a single video with multiple audio tracks. Elemental Stream packages video to support existing and future adaptive bit-rate protocols including Apple HLS, Adobe Dynamic Streaming, Microsoft Smooth Streaming and MPEG-DASH. Supported DRMs include Microsoft PlayReady, Verimatrix VCAS and Motorola SecureMedia. Via Nicolas Weil 
Television progress continues. In the late 1990s, the ITU defined the parameter values for HDTV and the 720p families. At its meeting in May 2012, ITU-R Working party 6C, the same group, made the leap forward to the parameter values for the next two generations of television formats. These are the (current name) 4K and 8K UHDTV formats - Ultra High Definition Television. They are constructed as multiples of the 1080p1920 format in ITU-R Rec. 709. WP6C is chaired by David Wood from the EBU Technology and Development Department. Thursday at 2pm ET I'll be moderating another StreamingMedia.com webinar, this time on the topic of "Best Practices for Transcoding and Video Workflow In The Cloud". Now that mobile devices are such an important target for most producers, does it make sense to start encoding all H.264 footage using the Baseline profile? From the tests that I performed this week, encoding all footage using this profile might save encoding and storage resources with minimal loss in quality.
At last November's Streaming Media West, the standing-room only crowd listened as the MPEG DASH Promoter's Group (DASH PG) espoused the yet-to-be-ratified International Standards Organization (ISO) standard for DASH (dynamic adaptive streaming over HTTP). Fast forward to April 2012, and the ratified ISO/IEC 23009 DASH train seems to be picking up steam, as companies from Microsoft to Wowza, Broadcast International to Fraunhofer Laboratories have pledged support.
From a media server perspective, Microsoft's announcement of Windows Azure Media Services, which we covered yesterday, didn't first strike us as a DASH play, but a blog post on the Microsoft Media Platform team blog brings DASH front and center as part of the Azure strategy.

The EBU is a member of a newly formed group aiming to create momentum towards the broad adoption of the MPEG-DASH standard. DASH (dynamic adaptive streaming over HTTP) is designed to address the dramatic growth of Internet video by defining a universal delivery format. The DASH Promoters Group, which is showing the first DASH live video channel playout at the Mobile World Congres in Barcelona this week, brings together a wide cross-section of media, telecoms and IT organisations. |
