Video: Preparing for 5G Video Streaming

Will streaming really be any better with 5G? What problems won’t 5G solve? Just a couple of the questions in this panel from the Streaming Video Alliance. There are so many aspects of 5G which are improvements, it can be very hard to clearly articulate for a given use case which are the main ones that matter. In this webinar, the use case is clear: streaming to the consumer.

Moderating the session, Dom Robinson kicks off the conversation asking the panellists to dig below the hype and talk about what 5G means for streaming right now. Brian Stevenson is first up explaining that the low-bandwidth 5G option really useful as it allows operators to roll out 5G offerings with the spectrum they already have and, given its low frequency, get a good decent a propagation distance. In the low frequencies, 5G can still give a 20% improvement bandwidth. Whilst this is a good start, he continues, it’s really delivering in the mid-band – where bandwidth is 6x – that we can really start enabling the applications which are discussed in the rest of the talk.

Humberto la Roche from Cisco says that in his opinion, the focus needs to be on low-latency. Latency at the network level is reduced when working in the millimetre wavelengths, reducing around 10x. This is important even for video on demand. He points out, though that delay happens within the IP network fabric as well as in the 5G protocol itself and the wavelength it’s working on. Adding buffers into the network drives down the cost of that infrastructure so it’s important to look at ways of delivering the overall latency needed at a reasonable cost. We also hear from Sanjay Mishra who explains that some telcos are already deploying millimetre wavelengths and focussing on advancing edge compute in high-density areas as their differentiator.

The panel discusses the current technical challenges for operators. Thierry Fautier draws from his experience of watching sports in the US on his mobile devices. The US has a zero-rating policy, he explains, where a mobile operator waives all data charges when you use a certain service, but only delivers the video at SD resolution at 1.5 Mbps. Whilst the benefits to this are obvious, it means that as people buy new, often larger phones, with better screens, they expect to reap the benefits. At SD, Thierry says, you can’t see the ball in Tennis, so there 5G will offer the over-the-air network bandwidth needed to allow the telcos to offer HD as part of these deals.

The panel discusses the problems seen so far in delivering MBMS – multicast for mobile networks. MBMS has been deployed sporadically around the world in current LTE networks (using eMBMS) but has faced a typical chicken and egg problem. Given that both cell towers and mobile devices need to support the technology, it hasn’t been worth the upgrade cost for the telcos given that eMBMS is not yet supported by many chipsets including Apple’s. Thierry says there is hope for a 5G version of MBMS since Apple is now part of the 3GPP.

CMAF had a similar chicken and egg situation when it was finalised, there was hesitance in using it because Apple didn’t support it. Now with iOS 14 supporting HLS in CMAF, there is much more interest in deploying such services. This is just as well, cautions Thierry, as all the talk of reduced latency in 5G or in the network itself won’t solve the main problem with streaming latency which exists at the application layer. If services don’t abandon HLS/DASH and move to LL-HLS and LL-DASH/CMAF then the improvements in latency lower down the stack will only convey minimal benefits to the viewer.

Sanjay discusses the problem of coverage and penetration which will forever be a problem. “All cell towers are not created equal.” The challenge will remain as to how far and wide coverage will be there.

The panel finishes looking at what’s to come and suggests more ‘federations’ of companies working together, both commercially and technically, to deliver video to users in better ways. Thierry sums up the near future as providing higher quality experiences, making in-stadia experiences great and enabling immersive video.

Video: Everyone is Streaming; Can the Infrastructure Handle it?

How well is the internet infrastructure dealing with the increase in streaming during the Covid-19 pandemic? What have we learnt in terms of delivering services and have we seen any changes in the way services are consumed? This video brings together carriers, vendors and service providers to answer these questions and give a wider picture.

The video starts off by getting different perspectives on how the pandemic has affected their business sharing key data points. Jeff Budney from Verizon says that carriers have had a ‘whirlwind’ few weeks. Conviva’s José Jesus says that while they are only seeing 3% more devices, there was a 37% increase in hours of video consumed. Peaks due to live sports have done but primetime is now spread and more stable, a point which was made by both Jeff Gilbert from Qwilt as well as José.

“We’ve seen a whole year’s worth of traffic growth…it’s really been incredible” — Jeff Budney, Verizon

So while it’s clear that growth has happened, but the conversation turns to whether this has caused problems. We hear views about how some countries did see reductions in quality of experience and some with none. This experience is showing where bottlenecks are, whether they are part of the ISP infrastructure or in individual players/services which haven’t been well optimised. Indeed, explains Jason Thibeault, Executive Director of the Streaming Video Alliance, the situation seems to be shining a light on the operational resilience, rather than technical capacity of ISPs.

Thierry Fautier from Harmonic emphasises the benefits of content-aware encoding whereby services could reduce bandwidth by “30 to 40 percent” before talking about codec choice. AVC (A.K.A. H.264) accounts for 90%+ of all HD traffic. Thierry contents that by switching to both HEVC and content-aware encoding services could reduce their bandwidth by up to a factor of four.

Open Caching is a working group creating specifications to standardise an interface to allow ISPs to pull information into a local cache from service providers. This moving of content to the edge is one way that we can help avoid bottlenecks by locating content as close to viewers as possible.

The elephant in the room is that Netflix reduced quality/bitrate in order to help some areas cope. Verizon’s Jeff Budney points out that this is contra to the industry’s approach to deployment where they have assumed there is always the capacity to provide the needed scale. If that’s true, how can one tweet from a European Commissioner have had such an impact? The follow on point is that if YouTube and Netflix are now sending 25% less data, as reports suggest, ABR simply means that other providers’ players will take up the slack, as is the intent-free way ABR works. If the rest of the industry benefits from the big providers ‘dialling back’ is this an effective measure and is it fair?

The talk concludes hitting topics on ABR Multicast, having more intelligent ways to manage large-scale capacity issues, more on Open Caching and deliver protocols.

Video: Simplifying OTT Video Delivery With SCTE 224

Life used to be simple; you’d fire up your camera, point it at a presenter and it would be fed to the transmitter network. When on-going funding came into play, we wanted each transmitter to be able to show local ads and so, after many years, SCTE-35 was born to do exactly that. In today’s world, however, simply telling a transmitter when to switch doesn’t cut it. To deliver the complex workflows that both linear and OTT delivery demand, SCTE 224 has arrived on the scene which provides very comprehensive scheduling and switching.

Jean Macher, from Harmonic explains this need for SCTE 224 and what it delivers. For instance, a lot of SCTE 224 is devoted to controlling the US-style blackouts where viewers close to a sports game can’t watch the game live. Whilst this is relatively easy to deal within the US for local terrestrial transmitters, in OTT, this is a new ability. Traditionally, geo-location of IP addresses is needed for this to work where each IP address is registered against a provider. If this provider is Chinese, then at the very least, you should be able to say that this IP address is in China. However, for ISPs who have an interest in the programming, they can bring in to effect their own data in order to have very accurate geolocation data.

SCTE 224, however, isn’t just able blackouts. It also transmits accurate, multi-level, schedule information which helps to schedule complex ad breaks providing detailed, frame-accurate, local ad insertion.

It shouldn’t be thought that SCTE 35 and SCTE 224 are mutually exclusive. SCTE 35 can provide very accurate updates to unscheduled programmes and delays, where the 224 information still carries the rich metadata.

To finish up the talk, Jean looks at a specific example of the implementation and how SCTE 224 has been updated in recent years.

Webinar: Scaling Video Delivery

There is no doubt that streaming video is here to stay. Every month, more consumers log into and subscribe to one or more OTT services. But as those services grow beyond geographical borders, providers are forced to ensure that their offerings can meet the demands of a swelling user base located around the world. Given that this involves employing the public Internet to deliver video to different pockets of the globe, OTT operators often struggle with implementing the best video delivery architecture: what infrastructure to purchase, to install, where & which partners to employ, and how to ensure the best possible viewer experience. This webinar explores some of the proven methods for scaling video delivery as well as best practices employed by some of the world’s biggest streamers.
