Multicast ABR is a mix of two very beneficial technologies which are seldom seen together. ABR – Adaptive Bitrate – allows a player to change the bitrate of the video and audio that it’s playing to adapt to changing network conditions. Multicast is a network technology which efficiently sends a video stream over the network without duplicating bandwidth.
ABR has traditionally been deployed for chunk-based video like HLS where each client downloads its own copy of the video in blocks of several seconds in length. This means that you bandwidth you use to distribute your video increases by one thousand times if 1000 people play your video.
Multicast works with live streams, not chunks, but allows the bandwidth use for 1000 players to increase – in the best case – by 0%.
Here, the panelists look at the benefits of combining multicast distribution of live video with techniques to allow it to change bitrate between different quality streams.
This type of live streaming is actually backwards compatible with old-style STBs since the video sent is a live transport stream, it’s possible to deliver that to a legacy STB using a converter in the house at the same time as delivering a better, more modern delivery to other TVs and devices.
It thus also allows pure-streaming providers to compete with conventional broadcast cable providers and can also result in cost savings in equipment provided but also in bandwidth used.
There’s lots to unpack here, which is why the Streaming Video Alliance have put together this panel of experts.
Whether or not edge computing is the next generation of cloud technology, the edge plays a vital role in the streaming video experience. The closer a video is stored to the requesting user, the faster the delivery and better the experience. But, streaming also provides a lot more opportunity for interactivity, engagement, and data collection than traditional broadcast television. That means as the edge grows in compute capacity and functionality, it could enable new and exciting use cases, such as AI, that could improve the viewer experience. In this webinar, we’ll explore the state of edge computing and how it might be leveraged in streaming video.

Streaming continues to grow, in amount streamed, in people consuming it and in importance within this and other industries. One things which has always been an enabler yet made streaming harder to deploy is its rapid evolution. Whilst this has been a boon for smaller, nimbler companies – both content producers and service providers – the streaming has now arrived at most companies in one way or another and this breadth of use-cases has kept streaming tech moving forward and showing no signs of abatement.
Some aspects are changing. For instance we are seeing the first patent-free MPEG standard proposals (EVC, which has basic patent-free functionality and a better performing patent-controlled profile) on the heels of AV1. We’re seeing low-latency efforts such as CMAF taking hold as an alternative to WebRTC. With CMAF being much closer to the ever popular HLS, this may well beat out WebRTC in deployments at the cost of a slightly higher, but much improved latency.
To bring all of this in to focus for 2019, Jason Thibeault from the Streaming Video Alliance is bringing together a panel of experts to look at the coming trends and to give us an idea of what to look out for, and how to make sense, of 2019’s year of video delivery.
Limelight, Streaming Video Alliance and Videonet come together to discuss the introduction of WebRTC’s sub-second latency for live streaming which is opening the way for a ‘better-than-broadcast’ experience – enabling new ways to engage viewers and monetise them.
WebRTC provides real-time video delivery and can now be implemented in a CDN environment for large-scale distribution and has extremely low latency.
This webinar covers:
Making WebRTC part of your workflow
Compression, DRM & ad insertion
Innovation opportunities for broadcasters and challenger OTT providers
Special focus on increasing viewer engagement
creating new revenue streams.
New business partnerships
Optimisation for multiscreen television & connected TV devices
The Streaming Video Alliance are back with a packed panel of experts discussing the move from broadcast channels to the cloud.
The real transition from traditional TV broadcast to online video is happening behind the scenes as incumbents and new providers embrace cloud resources to provide a scalable, distributed means to reach the widest possible audience. But the cloud is complicated. With a myriad of providers and a bevy of services available, providers need to understand both how the cloud can help streaming video workflows as well as the challenges involved with implementation and integration. In this panel, you’ll hear experts discuss a variety of challenges with cloud-based workflows, the growing importance of edge computing, and best practices for adopting cloud technologies in video delivery.

Continuing the Streaming Video Alliance’s great webinar series, Jason Thibeault is back to discuss the consumer demand to download video and how to implement it. Joining Jason to share his experience and opinions is Joshua Pressnell, CTO of Penthera.
One thing is clear about consumer behavior when it comes to watching video-on-demand: people want to watch it whenever and wherever they want. Unfortunately, especially as more consumers gravitate towards mobile devices on inconsistent Wi-Fi and cellular networks, achieving a high-quality experience is fraught with difficulties. Enter download-to-go. This functionality, pioneered by Netflix and Amazon, allows consumers to download content to their phones for off-line viewing, ensuring the highest quality viewing experience without having to worry about spotty network coverage. But how do you implement this solution? Is there a way this solution can be applied to connected storage in the home?
In this discussion, you’ll learn about the intricacies involved in implementing download-to-go functionality, how the feature is evolving to potentially make use of in-home storage, and many of the challenges associated with providing this kind of service to subscribers.
Joshua Pressnell joined Penthera after a long career as a military contractor developing integrated sensor systems and standards. Pressnell brought extensive experience in embedded systems, signals intelligence, sensor data fusion, and real-time software to the mobile software development industry, and quickly built a stellar reputation as an independent developer of top-ranked and top-grossing iOS mobile apps. Pressnell joined Penthera in 2011 as the iOS Team Lead, eventually taking on the role of Director of Engineering, and now Chief Technical Officer.

The Streaming Video Alliance is back with the next in their webinar series and the focus turns to churn.
Viewer churn is the OTT killer. But keeping subscribers engaged and coming back to a service involves more than just great content. It requires a keen eye on the data—from ensuring a great Quality of Experience (QoE) to making smart marketing decisions about content to providing excellent customer service, data is key.
What should you be measuring?
What are the key metrics and their thresholds?
How do you implement all of this into an existing workflow?
This panel will explore the kind of data that can have a meaningful impact on an OTT experience, best practices for measuring different elements within the workflow, and the techniques to capture the data that you need.

When it comes to online video, there are few issues more annoying to viewers than poor visual quality. A bad visual experience can significantly impact the user’s Quality of Experience (QoE). But what makes one video look better? How can you preserve the visual acuity of source content after transcoding? And, more importantly, how can you measure when that visual quality has degraded?
In this panel assembled by the Streaming Video Alliance, you’ll learn from leading experts on visual quality about the nuances of mitigating degradation during transcoding and how to implement measurement techniques to continually monitor the perceived quality of online video moderated by Jason Thibeault.

Sifting through the plethora of online codecs current and upcoming, Jason Thibeault and Thierry Fautier present this webinar from Harmonic and the Streaming Video Alliance
Recently, we have seen renewed attention on HEVC following Apple’s announcement to support the codec on their devices. 6 months later, Apple surprisingly became a founding member of the Alliance for Open Media (AOM) as a supporter of the AV1 codec. Yet, while the AOM group claims AV1 provides better performance than HEVC and will be offered royalty-free, there are some academic benchmarks who find AV1 inferior to HEVC on codec quality and performance.
In the meantime, MPEG / ITU-T is working on a next generation video codec, in a group called JVET (Joint Video Exploration Team) that has a mandate to deliver a video compression standard that can reach 50% over HEVC in 2020. Additionally, on the streaming side, we have seen the MPEG CMAF standard getting some traction not only to unify the HLS and DASH worlds, but also to offer the long awaited low latency delay solution for OTT.
This panel will discuss perspectives on these video compression technologies to help content providers, broadcasters, and service providers figure out the best path forward to distribute content over the internet in the coming years.
