What is MPEG DASH?

What is MPEG DASH? | Video Breakthroughs | Scoop.it

MPEG DASH is the latest hot topic in the online video space. Here we break down what it is, and what its implications might be for video delivery in the future.

 

MPEG DASH (Dynamic Adaptive Streaming over HTTP) is a developing ISO Standard (ISO/IEC 23009-1) that should be finalized by early 2012. As the name suggests, DASH is a standard for adaptive streaming over HTTP that has the potential to replace existing proprietary technologies like Microsoft Smooth Streaming, Adobe Dynamic Streaming, and Apple HTTP Live Streaming (HLS). A unified standard would be a boon to content publishers, who could produce one set of files that play on all DASH-compatible devices.

 

The DASH working group has industry support from a range of companies, with contributors including critical stakeholders like Apple, Adobe, Microsoft, Netflix, Qualcomm, and many others. However, while Microsoft has indicated that it will likely support the standard as soon as it’s finalized, Adobe and Apple have not given the same guidance, and until DASH is supported by these two major players, it will gain little traction in the market.

OTT video delivery : A properly engineered network decreases customer churn

OTT video delivery : A properly engineered network decreases customer churn | Video Breakthroughs | Scoop.it

There is a growing effort by broadcasters to make regular TV content available online. For example, the BBC has developed the BBC iPlayer and the bbc.co.uk website to support replication of most BBC broadcast material. The service has been outstandingly successful: 79.3 million requests were serviced in October 2009. NBC coverage of the 2010 Winter Olympics included live and recently recorded content, complete with commercials.


Whenever there is the possibility of a large or dynamic viewer audience, a reliable CDN is required. CDNs once only used to replicate website content around the world. Now, they have expanded dramatically to handle streaming media. Research and markets estimated the value of CDN services for 2008 at $1.25 billion, up 32 percent from 2007. Top CDNs include Akamai, Mirror Image Internet, Limelight Networks, CDNetworks and Level 3. Streaming media services must deal with content collected from disparate sources and distributed to a growing number of devices.

3 issues related to DASH

3 issues related to DASH | Video Breakthroughs | Scoop.it

Although it is not exactly what the MPEG scientists have promoted for a decade, most of today's video traffic is based on HTTP and TCP (Netflix player, Microsoft Smooth Streaming and Adobe OSMF). And it works. The video traffic is exploding: adaptive streaming already represents most than one third of the Internet traffic at peak time, and it is expected to prevail, even on mobiles. Facing this plebiscite, the MPEG consortium has launched the process of standardizing DASH into MPEG.

 

Despite the multimedia scientific community and the video standardization group are large lively communities, many research issues related to DASH have not been anticipated and sufficiently addressed :

- congestion control may be compromised

- encodings bottlenecks unpredictability

- lack of swarming support

The trials and tribulations of HTML video in the post-Flash era

The trials and tribulations of HTML video in the post-Flash era | Video Breakthroughs | Scoop.it

Adobe reversed course on its Flash strategy after a recent round of layoffs and restructuring, concluding that HTML5 is the future of rich Internet content on mobile devices. Adobe now says it doesn’t intend to develop new mobile ports of its Flash player browser plugin, though existing implementations will continue to be maintained.

 

Adobe’s withdrawal from the mobile browser space means that HTML5 is now the path forward for developers who want to reach everyone and deliver an experience that works across all screens. The strengths and limitations of existing standards will now have significant implications for content creators who want to deliver video content on the post-flash Web.

DASH bashing / Apple to Adobe & Microsoft: With friends like you, who needs enemies?

DASH bashing / Apple to Adobe & Microsoft: With friends like you, who needs enemies? | Video Breakthroughs | Scoop.it

After releasing his clear post on DASH today (http://bit.ly/seRUFr), Jan Ozer is talking back on issues raised by the dual norms M2TS/fMP4 of DASH and the doubts raised by lack of clear positions of Adobe - and its explicit alliance with Microsoft to bash Apple old-school approach. On top of this, DASH is not royaltee-free for the moment, so the future of this normative effort is quite unclear at this stage...

DASH of this, DASH of that... | Video Breakthroughs | Scoop.it

A few notes that didn't make it into the latest StreamingMedia article:

MPEG-DASH will never define a codec, but with DASH-264 there's a move to use an H.264 codec in an MP4 container with a common file format (CFF) and common encryption (CENC).... There's also a possibility of adding DASH-264 into the HTML5 standard, since W3C requires a codec to be considered in HTML5 but MPEG-DASH itself is codec agnostic.

FIMS and SOA : New architectures provide business agility

FIMS and SOA : New architectures provide business agility | Video Breakthroughs | Scoop.it

Broadcasters no longer have the monopoly on the delivery of A/V entertainment to the home. In the fiercely competitive world of media and entertainment, companies have to deliver more versions and formats, but without increasing their costs. A channel is now expected to have a Web presence, as well as mobile and tablet versions of their content.


Organizations like the EBU and Advanced Media Workflow Association (AMWA) are promoting the service-oriented architecture (SOA) as a route to provide the interoperable media services that can serve the new business requirements.


For the seasoned video engineer, the world of SOA introduces terms and concepts that at first encounter seem foreign and more suited to the IT specialist. As video processing migrates to the file domain, there is no option but to become familiar with what at first sight may appear alien.


Broadcast systems have evolved around the imposed workflow of the serial processing steps of videotape operations. Over time, many processes have moved from dedicated hardware boxes with SDI in and out to software applications on a network. A typical broadcast operation is now a hybrid of SDI and IP connections.


In many cases, the workflow remains as the original tape-based flow. Over time, other applications like asset and workflow management are layered over the entire process chain. The system has grown by accident, not by design, and become a web of custom or proprietary interfaces linking the many applications.


Sure it works, it was designed that way, but when the time comes to replace a component part — say the playout automation — the inflexibility of the system rapidly comes apparent. The parts of the system are linked by a web of custom APIs, often restricted to a specific release of a specific software application. It is just not possible to swap out the automation for the latest product without attending to the web of interfaces.


To meet the demands for new services to the public, the broadcaster must add facilities for a mobile news service, a 3-D channel and interaction with a social media website. Along comes CES and some new consumer device to consume content. How do you add support for this new device? Will it mean more custom interfaces or more special workflow applications? The EBU and AMWA are developing a Framework for Interoperable Media Services (FIMS), which aims to provide a new technology platform that leverages current IT practices, like the use of the SOA, to provide business agility and to control costs.

fMP4 : MP4 File Fragmentation for Broadcast, Mobile and Web Delivery

fMP4 : MP4 File Fragmentation for Broadcast, Mobile and Web Delivery | Video Breakthroughs | Scoop.it

Consistent multi-platform audio and video content delivery presents an ongoing challenge for broadcasters. Explosive smartphone and tablet growth on varying operating systems —Android, Apple iOS, or Windows Phone—threatens to create a user-experience divide between users on mobile devices, at the desktop or in the living room.

 

Tim Siglin's white paper explores fragmented MP4 files (fMP4) and considers whether the fMP4 format can replace legacy file formats.

Centralcasting: As trends and technology change, efficient playout is as important as ever | Video Breakthroughs | Scoop.it

The changing nature of media consumption has transformed the broadcast business model. Broadcasters are delivering a proliferation of media-related services to broader audiences via additional outlets and platforms. As the number of offerings has grown, however, average revenue per service has dropped. In a tough economic climate, and with IPTV and VOD services gaining ground, broadcasters face constant competitive and price pressures. And, while trends and evolving technologies continue to shape products, broadcasters are finding that it's more important than ever that their established channel playout operations run as efficiently as possible.

Everyone following their own path with HBB | Video Breakthroughs | Scoop.it

Do not expect rationalisation of standards and anything close to a pan-European, let alone a global specification for hybrid broadcast broadband (HBB). That was the message from a panel of experts at the OTT TV World Summit on Wednesday. Anthony Smith-Chaigneau, Chairman of the DVB-GEM Commercial Module, which determines what the DVB interactive TV standard needs to deliver for the market, suggested the problem is not a technical one but a human one. “There are plenty of standards but nobody is choosing them,” he said. “Everyone is fighting each other and following their own path.”

Zencoder and Aspera Team Up to Support Encoding of Large Video Files in the Cloud [PR]

Zencoder and Aspera Team Up to Support Encoding of Large Video Files in the Cloud [PR] | Video Breakthroughs | Scoop.it

Zencoder today announced that they have added support for Aspera's fasp high-speed transport technology to enable content providers to quickly and securely transfer large files to the cloud for transcoding.

 

While the scalability of the cloud is perfectly suited for processing-intensive jobs such as video transcoding, bandwidth constraints can make it a challenge to get video into and out of the cloud. With Aspera integrated into the Zencoder platform, video providers can now send video content to the cloud for transcoding at up to 700 Mbps. Once a file is in the Zencoder platform, it can be transcoded faster-than-real-time into several outputs formats simultaneously, creating massive efficiencies when compared to traditional transcoding methods.
