PeerApp, Limelight Networks and EdgeCast Networks jointly formed the open Content Service Extension initiative last year to enable an open-standards environment through which broadband operators can work collaboratively with Internet content providers and web applications to deliver services in a manner that efficiently utilizes network infrastructure and maximizes subscriber Quality of Experience (QoE). The CSE architecture allows CDNs and content service providers to extend their business logic and delivery footprint deeply into operator networks, through invocation of network functions and capabilities deployed and controlled by the operator. It also establishes a mechanism through which operators can be fairly compensated for the role their infrastructure and network capabilities play in service delivery. In addition to participating in this demonstration, Sandvine will also be formally joining the Content Service Extension initiative.
The demonstration features managed delivery of 4K video content from Limelight's global CDN footprint into the home, triggering operator caching and network Quality of Service (QoS) extension services in a trusted and controlled fashion. The operator-side implementation of the CSE service architecture includes PeerApp's UltraBand cache and CSE controller platforms as well as Sandvine's Service Delivery Engine (SDE).
Bridge Technologies has launched PocketProbe, an iPhone app that enables objective analysis of real network performance of streaming media, in a simple to use, easy to understand tool that technical staff can carry anywhere. PocketProbe contains the same OTT Engine found in the company’s VB1, VB2 and 10G VB3 series digital media monitoring probes, enabling confidence validation and analysis of http variable bit-rate streams from any location.
PocketProbe is available in two versions: the free application can validate five HLS streams in round-robin mode, provide analysis and manifest consistency alarms, play back media in the various profile bit-rates, and graphically display the actual chunk download patterns and bit-rates. The full version also offers the ability to validate HDS and SmoothStream manifest files and store twenty-five streams with all profiles.
Agama Technologies, the video service quality assurance expert, today announces that it is launching a unique Churn Identification Application addition to the reputable Agama DTV Monitoring Solution at IBC2012. This latest innovation brings enhanced support to TV operators worldwide in their mission to reduce churn rates, thereby securing higher revenues and reduced costs for customer acquisition. A strategy to actively reduce churn rates naturally entails identifying those customers at risk of leaving the service. Insight into and understanding of the customer experience and quality distribution is essential to be able to accomplish that. At IBC2012, Agama is launching a unique Churn Identification Application extension to its powerful DTV Monitoring Solution, which efficiently can identify customers experiencing problems and at risk of churning. It utilizes intelligent analytics to data mine the real-time, 24/7 service quality monitoring data for every single customer, and it is seamlessly scalable to operators with millions of subscribers. With support of automation and proactive workflows, the extension enables operators to act to retain the customer - before he or she even decides to move to the competition.
Assuming responsibility for the quality of video that traverses relatively unmanaged networks to unmanaged endpoints poses new challenges for Pay TV operators. Accustomed to spotting problems within managed networks, traditional test and monitoring systems accordingly are shifting into new territory.
S3 Group, a global enabler of the highest quality digital TV Content Delivery Platforms, is demonstrating the importance of second screen and Connected TV automated testing at The Cable Show 2012. The company will showcase how automated testing can make the difference between the successful adoption of new applications and services on connected devices versus a 'try once, turn off' experience. Specifically, attendees will see: - Connected TV Testing - Application Validation - Multi-screen Device Diagnostics - StormTest Development Center
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.

When packets are lost over a TCP connection, they’re retransmitted. This slows delivery 50 percent to ensure that the replacement packets make it through. Roy sites a study by Vern Paxson, a computer science professor at the University of California at Berkeley, that shows most homes have packet loss of 2 percent. Increased interference from mobile devices will compound the problem, Roy says. Packet Express circumvents this slow down by replacing lost packets with an error correction technology, one that doesn’t force a retransmission. It transforms packets using high order linear algebra, Roy says, and delivers substitutes for any packets lost. It also determines when networks are congested and alters the pace of the TCP transmission for optimal delivery. Rather than sitting on the network, Packet Express is integrated into an iOS or Android client application. App makers simply need to include the Q Factor library in their video players and recompile them. The code adds 500kb of data.
Agama Technologies, the video service quality assurance expert, is introducing the next generation of its Analyzer OTT for adaptive bitrate (ABR) streaming services at TV Connect 2013. The Analyzer OTT supports continuous 24/7 monitoring as well as testing and troubleshooting applications, making it ideal in all phases of deployment, operation and expansion. Both Microsoft Smooth Streaming services and Apple HTTP Live Streaming services can be analyzed in any combination. Sophisticated multi-dimensional presentation of QoE and QoS with timeline analytics provide a solid understanding of relevant technical quality parameters and how they affect the viewing experience.
Pay TV operators and their technology partners both are keen to promote quality—high quality, to be exact. In recent years, the technical community has shifted some attention from one related gauge, quality of service (QoS), to a more consumer-centric metric, quality of experience (QoE) How do these terms compare?
Sometime during the past five years, streaming video on demand from the Internet became a respectable delivery method. Today, traditional broadcasters, networks and many upstarts deliver a breathtaking number of online playbacks every day, and suddenly there needed to be methods for monitoring, testing and measuring the stability and reliability of this new delivery medium. There’s even a new name for video that’s delivered online on demand to viewers: over-the-top (OTT) video.
Broadcasters are great at creating high quality content, but delivering the content online has been a puzzle as far as ensuring that viewers got an experience as good as the broadcast signal. Fortunately, several companies responded with a variety of products to allow just about every facet of online video to be tested and measured.
Harmonic Inc. today announced Iris 2.0, the newest version of its video quality monitoring and analytics software suite. Featuring an enhanced graphical user interface and integration with several of the industry's leading monitoring solutions.
Pixelmetrix will unveil its new OTT Media Grinder (OMG), a comprehensive system for validation of Over-The-Top Delivery Infrastructure. The OMG enables operators to qualify and periodically audit OTT Service Quality by simultaneously emulating thousands of OTT clients – generating large amounts of OTT transaction traffic into the network. The OMG simulates thousands of OTT clients (iPhone, iPad, etc) with multiple user-defined behaviours. Pools of clients can behave well (for example, consume content to the end), while other pools of clients can randomly change speeds, drop connections, or flap between adaptive bitrates.
The trend towards cloud-based service delivery is creating a need for products that enable Quality of Service (QoS) over unmanaged networks, according to Swedish owned distributed video network technology vendor Edgeware. The company has developed a strategy called Distributed Video Delivery Network (D-VDN) to address this need, and announced the first product in this line, the Convoy VDN, at IBC2011. This helps operators deploy advanced video services with acceptable QoE over the unmanaged network between a cloud service and its subscribers, with the ability to tie in with a wholesale CDN (Content Delivery Network).
IneoQuest Technologies, Inc., the global provider of advanced video quality and service assurance solutions, and Envivio, a leading provider of live and on-demand multi-screen IP video processing and delivery solutions, today announced that they are collaborating to provide sophisticated quality assurance tools to Content Delivery Networks (CDNs) and over-the-top services (OTT) using adaptive bit rate video delivery technology.
