Broadpeak takes the CDN further into the home

Broadpeak takes the CDN further into the home | Video Breakthroughs | Scoop.it

As we reported previously, the Broadpeak solution introduces very lightweight clients into the home router/gateway and these intercept the unicast stream requests made by a tablet or smartphone to an origin server. The client looks for a multicast stream of the linear content instead. The platform operator works with a content owner to make the most popular channels available in multicast, perhaps during peak times or for popular shows or live sports, or even 24/7. The nanoCDN client receives this multicast stream instead, then converts it to unicast ABR (adaptive bit rate) inside the home so it can be watched on the multiscreen devices without any changes to their apps.


By replacing multiple unicast streams with a single multicast stream in the broadband network, nanoCDN reduces the bandwidth demands for linear/live video. nanoCDN is pioneering because of the way it harnesses multicast within a CDN environment and because it makes in-home devices an extension of the CDN.

2014 – The year of open standards?

2014 – The year of open standards? | Video Breakthroughs | Scoop.it

There is hope on the horizon. MPEG-DASH exists as an open alternative to these closed standards. Two of the three companies with proprietary closed standards have been actively involved in the formation and promotion of DASH. These efforts have been clearly successful, as DASH delivery of content is becoming more and more prevalent – for example, Netflix, Hulu and YouTube have all released versions of their content via DASH delivery. Through the efforts of Browser manufacturers, Media Source Extensions (another open standard), have become available in many browsers allowing delivery of DASH content without any additional plugins required.

 

Unfortunately, HLS remains the most common delivery format in the US, and Apple (the author/owner of HLS) has shown no interest in supporting MSE in their browser. A tipping point is clearly on the way, which will see a massive growth in DASH delivery. Eventually Apple will be forced to embrace the current open standard, or risk losing content which has made their platform so appealing. The irony of course is that Apple has done so much marketing touting themselves as leaders of the “open web” movement, and they are the long holdout stalling the success of this open standard.

MistServer: A Lightweight, Highly Scalable Media Server

MistServer: A Lightweight, Highly Scalable Media Server | Video Breakthroughs | Scoop.it

This white paper explores MistServer, a greenfield initiative by DDVTech BV, The Netherlands-based startup who recently created a lightweight, scalable media server. With a goal of solving significant media delivery problems, MistServer’s design offers benefits over current solutions.

 

Brains and brawn, just not in the same place. DDVTech’s MistServer is based on a philosophy that a media server should do what it does best: serve audio and video streams. They split the brawn (MistServer) from the brain (MistSteward, MistCenter, or a web control interface).

The State of Streaming Media Protocols 2013

The State of Streaming Media Protocols 2013 | Video Breakthroughs | Scoop.it

It's all about DASH: Adoption is moving at a rapid pace, as industry insiders see a strong need to get DASH implemented in the field in the coming year.

 

The Pantos spec, as it is known in the industry, is a series of working drafts for HLS submitted by two Apple employees as an information draft for the Internet Engineering Task Force. As of the time of this article, the Pantos spec is currently at informational version 10.

 

Much has changed between the early versions and the most recent v10 draft, but one constant remains: HLS is based on the MPEG-2 Transport Streams (M2TS), has been in use for almost 2 decades, and is deployed widely for varied broadcast and physical media delivery solutions.

 

In that time frame, however, little has changed for basic M2TS transport stream capabilities. For instance, M2TS still lacks an integrated solution for digital rights management (DRM). As such, all HLS versions cannot use "plain vanilla" M2TS, and even the modified M2TS used by Apple lacks timed-text or closed-captioning features found in more recent fragmented elementary stream streaming formats.

 

Yet Apple has been making strides in addressing the shortcomings of both M2TS and the early versions of HLS: In recent drafts, the HLS informational draft allows for the use of elementary streams, which are segmented at the time of demand rather than beforehand. This use of elementary streams means that one Achilles' heel of HLS -- the need to store thousands, tens of thousands, or hundreds of thousands of small segments of long-form streaming content -- is now eliminated.

 

Google, with its Android mobile operating system platform, has adopted HLS for Android OS 4. Some enterprising companies have even gone back and created HLS playback for earlier versions of Android OS-based devices.

The once and future efficiencies of VBR

The once and future efficiencies of VBR | Video Breakthroughs | Scoop.it
Service providers deploying IPTV have tended to use constant bit rate (CBR) as opposed to variable bit rate (VBR) encoding. Several emerging use cases, however, could bring VBR back into play. It also is playing a surreptitious role in making adaptive bit rate (ABR) streaming even more efficient.

Dolby flies flag of ABR-friendly audio

Dolby flies flag of ABR-friendly audio | Video Breakthroughs | Scoop.it

Audio sometimes gets lost in the noise of video technology. But what more quickly degrades a viewer’s quality of experience (QoE) than a voice not synchronized with picture or loudness levels that fluctuate wildly between channels? The bottom line upfront: Pay TV operators neglect audio at the peril of losing both eyes and ears of their customers.

 

One company that agreed with the need for an efficient solution and went through this process of integrating with Dolby is RGB Networks. The driver from RGB’s perspective was ABR streaming to the set-top box, which has audio requirements higher than second-screen devices.

 

Ramin Farassat, RGB Vice President of Product Marketing and Business Development, said this recent enhancement of Dolby’s technology allows for stereo to run at a low bit rate, and then as network conditions improve, it jumps to 5.1. “If I were doing it with today’s technology, there’s a break,” he said. “With Dolby, it’s a seamless switch.”

Venera Pulsar Review: Quality Control for Adaptive Streaming

Venera Pulsar Review: Quality Control for Adaptive Streaming | Video Breakthroughs | Scoop.it

Quality control software has been around for a while now; for an overview of the category and quick look at four entrants, check out "Quality Control Roundup: Catch the Mistakes Before They Go Live." Producing files for adaptive streaming throws some new wrinkles into the mix, however, both from a format and a management perspective. One of the first products that attempts to simplify QC for adaptive streams is Venera Technologies' Pulsar, which now can analyze adaptive streams produced for HTTP Live Streaming (HLS) and Smooth Streaming, but not HTTP Dynamic Streaming (HDS). In this review I take a look at Pulsar as a whole, with a focus on these new adaptive streaming-related capabilities.

Adaptive Streaming's Primetime Challenge

Adaptive Streaming's Primetime Challenge | Video Breakthroughs | Scoop.it

Video service providers have become enamored of adaptive bit rate streaming as a way to deliver video to tablets and smartphones, but not everyone believes the technology will become the primary way video is delivered to the home.

 

HTTP Adaptive Streaming (HAS) "is not ready for primetime TV," declared Pieter Liefooghe, chief solution architect and solution line manager at the video solutions and integration organization of Alcatel-Lucent, during a panel on the topic at last week's Managing & Monetizing OTT Video event in Boston. HAS is "okay for a single-stream, OTT-style of service, but as a basis of a primetime TV service, it's a challenging proposition," he added.

 

But this doesn't mean HAS will never be suitable for primetime TV, as the shortcomings identified by Liefooghe relate to "out-of-the-box" HAS technology. He said, for example, that AlcaLu has identified some technologies and techniques that can be done on the routing platform and the content delivery network (CDN) to boost HAS performance enough to address some of its technical shortcomings. And he insisted there are ways to pare delays down to six seconds while still guaranteeing continuous playback.

 

"There's a future for HAS as the new RTP," Liefooghe concluded.

SDC: Scalable Description Coding for Adaptive Streaming Media (Academic paper)

SDC: Scalable Description Coding for Adaptive Streaming Media (Academic paper) | Video Breakthroughs | Scoop.it

Abstract : Video compression techniques enable adaptive media streaming over heterogeneous links to end-devices. Scalable Video Coding (SVC) and Multiple Description Coding (MDC) represent well-known techniques for video compression with distinct characteristics in terms of bandwidth efficiency and resiliency to packet loss. In this paper, we present Scalable Description Coding (SDC), a technique to compromise the tradeoff between bandwidth efficiency and error resiliency without sacrificing user perceived quality. Additionally, we propose a scheme that combines network coding and SDC to further improve the error resiliency. SDC yields upwards of 25% bandwidth savings over MDC. Additionally, our scheme features higher quality for longer durations even at high packet loss rates.

What Happens When HTTP Adaptive Streaming Players Compete for Bandwidth?

The College of Computing at Georgia Institute of Technology and the Video & Content Platforms Research and Advance Development Division at Cisco have published a white paper on HTTP adaptive streaming. The paper focuses on the problem of competing video players and describes how the typical behavior of an adaptive streaming player in its Steady-State, which includes periods of activity followed by periods of
inactivity (ON-OFF periods), is the main root cause behind three performance problems: player instability, unfairness between players, and bandwidth underutilization.

3 Different Approaches to Manifest Manipulation

For providers trying to overcome the limitations of ABR protocols, manifest manipulation is quickly gaining traction as a solution. But which approach is right for your organization?

There are several different approaches to manifest manipulation but in general they can be divided into three primary types. In these weeks blog we’ll look at them in detail, as well as the benefits and limitations of each:

1.  Manifest “Conditioning”

2.  Manifest Builder or “Playlist Re-writing”

3.  Dynamic Manifest Manipulation (DMM)

Content replacement: New protocols enable flexibility in simulcast services

Content replacement: New protocols enable flexibility in simulcast services | Video Breakthroughs | Scoop.it

What is significant about all ABR formats is that they separate the control aspects of the protocol from the video data. They share the general concept that video data is encoded into chunks and placed onto an origin server or a CDN. To start a streaming session, client devices load a manifest file from that server that tells them what chunks to load and in what order. The infrastructure that serves the manifest can be completely separate from the infrastructure that serves the chunks.

 

The separation of these concerns provides a basis for dynamic content replacement, as it is possible to dynamically manipulate the manifest file to point the client device at an alternative sequence of video chunks that have been pre-encoded and placed on the CDN. The ability to swap chunks out in this way relies on the encoding workflow generating video chunks whose boundaries match possible replacement events.

Intéressant mais sur le slide 11 de comparaison il y aurait des question à poser.

Notamment le ressenti du client, qu'est ce qui est le plus intéressant :
-Une qualité quasi constante avec la solution Apple (seulement 7 switch)
-Une qualité variable mais "en moyenne" supérieure (DASH + SVC 107 switch soit plus d'un par minute) ?

Comment visuellement ce traduit ces switch, les pics haut, les pics bas ?

Quel est le gain de qualité visuel entre un débit moyen à 1162kbps et 2738kbps ?

HTTP Streaming: Load Balancing Tips

HTTP Streaming: Load Balancing Tips | Video Breakthroughs | Scoop.it

In most cases, modern video content delivery systems are based on HTTP Streaming. This technology delivers video in a series of fragments (chunks), several seconds each. The most popular video delivery formats are Apple HTTP Live Streaming and Adobe HTTP Dynamic Streaming. In the near future, MPEG DASH will also probably become popular. The benefits offered by this type of delivery consist in a more stable video platform operation over a heterogeneous public network (Internet) and use of existing mechanisms of traditional CDN networks (HTTP chunk caching). But often traditional media is not sufficient, and large-scale online video services usually require a more flexible management of video content delivery. In our projects, we use our Video Load Balancer. In this post, we are going to outline the basics of its operation that might be helpful to your projects regardless of the load balancing technology you use.
