“There are a growing number of smartphones capable of shooting 4K ultra HD video. But there’s really not much reason to watch 4K video on a phone. You wouldn’t be able to see most of the detail on a pocket-sized screen.”
This article focuses on the live streaming DASH features enabled by Azure Media Service, and how they can be used to deliver live and video on demand adaptive streaming to Web browsers and new devices of all types, which are adding support for the DASH standard. DASH live streaming is now available for public preview, and will graduate to “general availability” with normal service level agreements after the preview period.
DASH output is a runtime option for all live and VOD streaming from Azure Media Services. A player can request a DASH Media Presentation Description manifest and compatible ISO Base Media File Format “Media Segments” just by including a DASH format tag in each URL request. The same files or live stream can be delivered in Microsoft Smooth Streaming, Apple HLS, or Adobe HDS by indicating any of those formats in the URL format tag. This enables the introduction of DASH to new browsers and devices while maintaining compatibility with legacy players and formats. The ability to dynamically package media segments in realtime is essential for low latency live streaming, as well as efficient multiplatform support.
Sure, UHD is wonderful and we all want it (if we have the room and the money) and unlike 3D it is almost certainly going to reach market in a meaningful way, and fairly soon, but there is one story that dwarfs everything at IBC this year and that is virtualization - and more specifically, the incredible speed with which it is becoming possible to virtualize almost all the functions of a headend into data centres and clouds.
The first commercial implementations of Haivision's HEVC encoding allied with the company's Secure Reliable Transport (SRT) protocol, are due in the new year.
HEVC was perhaps the hottest topic at this year's IBC show in September, but while most demos sought to showcase 4K HEVC in a controlled environment,Haivision took a different tack. The company showed off its HEVC encoding delivered via Haivision's proprietary Secure Reliable Transport (SRT) protocol—sent over the public internet from a hotel close to the conference venue.
While the mainstream broadcasters are still figuring out how to provide 4K broadcasts it appears Netflix may in 2014 be offering 4K (3840 x 2160 pixels) resolution streams. The US baseddslreports.com indicates that this ultra HD stream would run at around 15 Mbps.
Only recently Netflix added super HD to its video on-demand service, which was a less compressed HD stream. The high price of 4K televisions will put many off but with Netflix offering the streams at least those with the money will now have some content thus breaking the chicken and egg situation of what to watch that exploits your recent purchase.
The DASH-IF continues move toward interoperability points and even H.265 integration. Publication will follow in mid-July.
Interoperability for DASH-AVC/264 surrounds the use of the H.264 video codec, also known as the Advanced Video Codec (AVC). DASH-AVC/264 combines AVC with the AAC audio codec and the fragmented MP4 file format (also known as the ISO Base Media File Format).
Publication is expected on July 13, including about 25 test cases and a few real-world test scenarios for bitrate variation. Conformance software is also anticipated to be available around mid-July, along with several reference clients that are released under the BSD-3 license.
DASH-IF has defined test cases for interoperability points (IOPs) to implement conformance testing. One IOP that this site has covered, in terms of a DASH-AVC/264 client, is interoperability on adaptive streaming heuristics. The DASH-AVC/264 eliminates the need to interoperate for multiplexed media downloading, and also eliminates the need to interoperate with open group of pictures (GoP) switching, relying instead on closed GoP switching.
Apple has acquired Perceptio, a 45-year-old stage magician who specialises in sawing Vegas holidaymakers in half, with a 65% recombination success rate. Okay, not really. But that would be quite something, wouldn't it?

Eutelsat’s Smart LNB technology enables multicast streaming over Ku-band satellite spectrum, with multicast streams turned to unicast in the home to feed multiscreen devices without any changes to apps. The goal is to put satellite operators into the multiscreen and connected TV business without requiring terrestrial broadband and the unicast CDN costs that come with it. The company has three reference designs, has integrated with Cisco Videoscape and was demonstrating the technology at IBC.

Google today announced the launch of Web Designer, a new tool for building interactive HTML5 sites and ads. The company first hinted at this launch in June, but had been quiet about it ever since. Web Designer, which Google calls a “professional-quality design tool,” is now officially in public beta and available for download for Mac and Windows.
As Google notes in today’s announcement, Web Designer was developed to allow advertisers to easily create HTML5 ads for mobile and desktop. Until recently, Google argues, advertisers “didn’t have the tools they needed to easily develop content fit for today’s cross-screen experiences” and Web Designer aims to be the tool to create these experiences.
