SMPTE and DPP Collaborate in Pilot Project to Deliver Draft of First SMPTE Specification

SMPTE and the Digital Production Partnership (DPP) have announced the success of a first-of-a-kind pilot project to define a prototype SMPTE Specifications process. SMPTE and DPP have delivered the first draft SMPTE Specification, which focuses on the use of the Interoperable Master Format (IMF), or SMPTE ST 2067, for broadcast and online applications.

The DPP delivered the working drafts of the IMF Requirements and IMF Specification for broadcast and online applications to SMPTE last week at the HPA Tech Retreat in Palm Desert, California. The documents represent input by the DPP, SMPTE, the North American Broadcasters Association (NABA), and the European Broadcasting Union (EBU), as well as manufacturers and end users across the media industry.

Now out for public comment, the draft specification for IMF for broadcast and online applications will address constraints including MXF Track Files, composition playlists (CPLs), output profile lists (OPLs), and IMF packages. The specification will reference other activities as well, such as the EBU.io/qc project for carrying quality-control metadata and EBU-TT, and it includes optional methods for carrying traditional EBU-STL subtitles in Europe and CTA-608/CTA-708 captions in North America.

Built upon the IMF standard, this first SMPTE Specification will play a critical role in enabling broadcasters to use IMF workflows with their existing content archives, and it also will facilitate the realization of file-based interoperability on a large scale. By providing manufacturers with the guidance they need to move forward in designing and building readers, writers, and analyzers, the specification will bring the benefits of IMF more fully into the broadcast and online realm.

Once they are finalized, the new SMPTE documents will join other SMPTE technical publications, including standards, that help manufacturers, engineers, and technologists to develop new products and services in broadcasting, cinema, and online video. The draft documents are available here.

There’s an App for That? HTML5 vs Native for In-App Video Playback

Online video publishers that decide to launch a mobile app are faced with a decision between reusing their HTML5 player by embedding it in a native app, building a completely native playback experience, or a combination of both approaches. Initially, it may seem easiest to re-use your HTML5 player, but that is not always the best option from evidence we’ve seen in our comprehensive testing.

This post will evaluate the pros and cons of each approach. It will give some guidance for this important decision, and highlight why investing in a native video player gives your customers the best performance, feature set, and user experience.

Netflix is Giving this Show Away for Free to Make TV Better for All

It might not be the next Daredevil or House of Cards, but Netflix's latest production, called Meridian, might end up having the biggest impact on the world of video streaming. It attempts to do this by virtue of how visually complex it is, combining multiple sources of visual noise such as cigarette smoke, fog, and some film footage for good measure into a single shot of its 60 fps, 4K, HDR footage.

Test Footage
The reason for producing such a complicated bit of footage is to push Netflix's streaming technology to its limit. If you're working to optimize your codecs or streaming technology you might end up simplifying a part of the process that makes the technology unable to deal with a visually complex scene. Having a piece of footage available such as Meridian means that you can very quickly check to see if your technology is up to the task of dealing with the worst case scenario of footage.

Free for All
But better yet is the fact that Netflix is making the footage available under a Creative Commons license, meaning that other streaming companies will be able to use the footage to test their own technologies. Following open-source principles such as this is common in the software industry, but is much less prevalent in Hollywood where studios have maintained a tight grip on their intellectual properties. This has resulted in a relatively small pool of test footage being endlessly reused across the industry.

Netflix is hoping that by sharing this footage it can get companies cooperating more effectively and speed up the adoption of new standards such as Interoperable Master Format (IMF), a standard which greatly simplifies the process of having multiple copies of a film for use in different territories. So while it might not be the next big hit from Netflix, the impact of Meridian might just end up being felt for years to come.

Ultra HD Forum: Phase A Guidelines

The purpose of this document is to describe consistent methods for the creation and delivery of Ultra HD content for consumer distribution along with a uniform set of characteristics that may be combined to produce content that can be considered “Ultra HD,” referred to as “UHD Phase A” in this document.

The scope includes delivery via the Internet, satellite, terrestrial broadcast and cable as transmission methods. It does not include encode and delivery of content via storage media, such as Blu-ray disc, HDD, SCSA devices, or similar, nor does it include encode and delivery of Digital Cinema content.
