The next-generation of CDN needs to give service providers much greater control over bandwidth priorities in the home, Alcatel-Lucent believes. If there are multiple devices competing for bandwidth, you need to be able to say that a connected television needs priority for streaming and that a smartphone should be given a lower bitrate stream, for example.
“Service providers need a way to control the quality that is delivered to every screen and that is not possible today with adaptive bitrate streaming,” Mestric explains. “So in the CDN we will include a session manager that makes the CDN aware of all the different devices and session requests so that if you start to watch video on an iPhone and there is no congestion in the access network you will get the highest bitrate possible, but if someone else in the family turns on a connected TV device the service provider can then limit the bitrate profiles that can be accessed by the iPhone, for instance.”
Mestric points out that session prioritization could be useful if there is contention on mobile networks. Then a content provider could prioritize a premium subscriber over a basic subscriber so they get the higher bitrate if there is no chance to provide them both with the best possible experience.
Is there a way to extract the intra-frames and preserve them as-is from FFMPEG or similar program? I know you can extract frames to a sequence of JPEG images using -f image2 . But those are full images of each of the ...
Regular readers will know that there's a hard press to put DRM in the next version of HTML, which is being standardized at the World Wide Web Consortium (WC3), and that this has really grave potential consequences for the open Web that the WC3 has...
Cloud encoding vendor Encoding.com launched Vid.ly a couple of years ago to provide video creators with a way to publish a single universal video URL and then have that content accessible on any device.
Encoding.com is a massive cloud encoding service, supporting various output formats and many controls for fine-tuning encodes. The forever free trial is an ideal way to get started with their service and its new Tooltip ...
Rovi Claims to achieve transcoding conversion time savings via software using a single decoded stream and offering up to 10 simultaneous re-encodes for any given stream.
With today's announcement that it is releasing version 1.0 of the MainConcept software development kit (SDK) for H.265, Rovi Corporation hopes to jumpstart usage of High Efficiency Video Coding (HEVC) in existing digital media workflows.
"The new MainConcept HEVC SDK 1.0 not only enables developers to increase the ease with which high-quality video content is delivered through existing cable, internet and wireless channels," stated a company press release, "but it also features innovative new technology to significantly reduce content conversion times."
The new SDK offers an Application Programming Interface (API) and is based on the MainConcept library of codecs. The intent of the SDK and integrated API, according to Rovi, is to "ease the process of adding HEVC support to new or in-market solutions." The SDK also includes an HEVC encoder and decoder. It is available for Windows, Mac OS, and Linux, in both 32- and 64-bit version with a low-level C++ API and DirectShow filters.
Earlier this month the Web standards body, W3C, announced the first draft of the Encrypted Media Extensions (EME) specification, which will allow content providers to add content protection to HTML5 videos for the first time. While EME will not handle the encryption process or Digital Rights Management (DRM) system, it will provide a standard for third-party plug-ins to support DRM in the web browser. The news elicited a mixed response from web platform commentators but there is no doubting its significance for the digital TV community.
Right now, the appetite for HTML5 video is strong, as a platform for a consistent, cross-device viewing experience. Developed with the new breed of mobile and OTT-capable devices in mind, HTML5 makes it possible, in theory, to standardise playback on any device, via the browser, and eliminates the need for plug-ins to create rich video playback experiences.
While ideal for basic video playback, HTML5 has a way to go before it becomes a fully-fledged solution for the most demanding use cases of online video delivery. In the interim, workaround tools, and online video platforms have emerged to help content producers and developers deliver on the multi-platform promise.
At last, IPTV is getting a standard framework for interoperability of rights information as a result of cooperation between the International Electrotechnical Commission (IEC) and ITU.
The two bodies have come up with a new metadata standard to ensure that that multimedia content can be shared legally across different platforms by exchanging the relevant rights details.
The two agencies have been working on the standard for some years and have aligned their content technically so that the two combined effectively provide a super standard covering all the relevant bases. IEC 62698 recognizes that as consumers become increasingly mobile, IPTV services need to operate flexibly across multiple platforms while protecting content producers rights.
