What We Know About Streaming Behavior
Although we like to think of streaming and broadcast as very different, they aren’t really. Viewer behavior is relatively the same: most people watch video, whether streaming or from their cable provider, when they are at home. Yes, there are exceptions to that. Younger viewers probably watch short form content on their phones throughout the day (when they can), and older viewers might sneak a video (maybe a sporting event happening during working hours) from their desks. Although there’s not a lot of data available on when people like to watch streaming video, if watching video on services like Netflix, Disney+, and Hulu are anything like watching streaming video on Twitch, the peak time for video streaming, prior to the current situation, is most likely 6PM to 8PM on weekdays (according to TwitchTracker, there are 1.6M to 1.75M viewers during that window).
The Situation is Changing
The global COVID-19 outbreak, though, is changing that landscape. As more businesses send their employees home, where they can watch streaming video while working, as schools close and students go online to learn and play (perhaps spending hours bouncing around streaming sites like YouTube), as governments quarantine large swaths of citizens who can no longer turn to entertainment outside their homes, the potential for consistent streaming to happen at all times of the day is a distinct possibility. In fact, just consider some of these use cases:
- Gyms streaming workouts to people in their homes
- Colleges and K-12 shifting to online learning with recorded video lectures
- Performers and entertainers streaming their concerts and events (that’s happening right now in Austin, TX)
And although many streaming providers architect their platforms to handle scale, sustained scale is another issue entirely. What’s more, the profile has changed. Where the bulk of streaming used to happen in prime-time, it’s now happening throughout the whole day, radically changing the delivery profile. It’s no longer just an event, or just a new release. It’s the possibility of all day, every day.
Some Helpful Advice
To improve the streaming experience industry-wide, to make it even better than broadcast, we have to work together. We must share our insights, our failures, and our successes. This is why the Streaming Video Alliance exists: to provide a forum for this sharing and collaboration.
Listed below are some pieces of advice or things to consider from engineers and technologists in our member companies for dealing with the potential of consistent high-demand for streaming content that we might face over the next few months. Some of these ideas are very practical, others more observational, and some future-looking. Note, though, that these are the individual opinions of these members and/or their respective companies, not necessarily the Streaming Video Alliance.
News and Updates
As things happen which may impact global streaming as a result of the COVID-19 response, we will post them here.
European Commissioner Thierry Breton released a statement saying “streaming platforms, telecom operators and users, we all have a joint responsibility to take steps to ensure the smooth functioning of the internet during the battle against the virus propagation.”More info at: Fiercevideo French ISPs Might Restrict Streaming Traffic Announced: 03/16/2020
“…in case of saturation, operators do not rule out favoring professional use by reducing the bandwidth of entertainment sites. Netflix, YouTube, Fortnite and many other services could therefore have their speed limited, which can have consequences on the accessibility of certain services.”More info at: engnews24h.com Disney+ Makes Frozen 2 Available Early Announced: 03/13/2020
In response to schools closing and kids spending more time at home as a result of COVID-19 containment, the Walt Disney Company, made Frozen 2 available in the US and internationally on its Disney+ subscription streaming service three months ahead of schedule. The film will drop on Disney+ in the US beginning Sunday, March 15. Internationally, it will be available for streaming in Canada, the Netherlands, Australia, and New Zealand on Tuesday, March 17.More info at: Deadline.com

A lot of the live event capacity is structured around large events with many clients. Those kinds of streams will drop in number. I believe we’re going to see a shift to many much smaller streams, which by their nature will be somewhat less efficient. Quality will be somewhat lower. Live linear, and news channels in particular, will start to look like concert-type live events, with many people watching live press conferences to get their information. Adjusting those configurations proactively for higher scale and treating them like live event channels should be considered.

Network Operators can consider employing Multicast ABR for live streaming or 24/7 streamed channels. It is a great way to transport OTT video streams across a managed network. It can help because it scales based on the number of linear feeds, not the number of viewers.
Pierre-Louis Théron (CEO, Streamroot)
To handle an increased demand, a peer-assisted video delivery solution is ideal. The main advantage of this mode is that the more people watch, the more it scales and keeps the pressure on ISP peering points low. For instance, when the French president addressed the nation today on Monday evening. This traffic generated ten times higher traffic than usual Monday traffic. More than 500k people watched it streamed on the major French channels while consuming the CDN bandwidth of only 160k people.
Steve Miller-Jones (VP of Edge Strategy)
Unfortunately, there are always those willing to try and take advantage of any situation, and there is likely going to be a higher risk of video piracy to go along with increased viewing behavior. Streaming platforms and content owners should consider how they are protecting the rights and content that they are publishing and enabling themselves to combat any increase in piracy.
J. Martin (CIO)
Companies that use VPN for remote access should consider a feature called “Split Tunneling.” During a remote access session, traffic is tunneled through an encrypted path to the data center. This works great for all traffic which is hosted in the company data center but does very little for WebEx, Zoom, or high bandwidth intensive applications. Most VPN clients today support what is called “Split Tunneling;” this does add additional risk at the client (that latest software should be installed) but it allows you to select which traffic can go right out to the Internet thus keeping high speed bandwidth out of your data center.

Network traffic is rapidly increasing. To improved the delivery of video streams to meet demand, Open Cache technologies can optimize and mitigate the rise of traffic. Also, local buffering of video streaming, such as using the memory in edge devices, can also help to mitigate congestion.
Marc Maycas (VP of Product Solutions)
Be prepared to adapt your content delivery strategy to ensure high quality standards. It is key to optimize the quality of your content, adjusting bitrate to match different device usage. Now that people are at home, Smart TVs and Desktop will gain importance whereas you can afford less quality on mobile streaming due to reduced usage. In normal circumstances, video services tend to want to ensure the best quality possible in mobile, but in these circumstances it is worth checking the data to see whether the demand is worth it. If you can reduce top quality bitrate layers in a calculated manner, both join times and buffer ratios will decrease due to lower network congestion.
Dr. Abdul Rehman (CEO)
Residential networks might be experiencing all-day peak hours and operate above stable capacity levels. To manage this, you need to meet content demand without degrading the viewer experience. An understanding of content demand on an asset level, linear or VOD, is half the job. Our recommendation is to shift resources between assets based on changes in content demand and viewer experience expectations. If the appropriate tools are available, the first step is to select the realistic viewer experience given the constraints and re-allocate resources to reach those levels. Step two is to shift additional resources to the most relevant, consumed, or complex content to retain the best experience possible under the current conditions.

Here are four tricks to help scale up quickly and remotely in an emergency. First, adapt the traffic to the specific devices and portions of the network you are targeting. For example, in the portion of a network that is sensitive you can remove 4K video. Second, if you have a hardware-agnostic CDN solution, you can scale it up by adding extra nodes in the public cloud, or by repurposing hardware that is normally used for other purposes. Third, increase the transcoding quality to have better-compressed streams and thereby reduce bandwidth consumption. If this means you use too much processing power for encoding, then you can reduce the number of profiles on certain channels. Finally, you can remove the DRM protection to make it easier to scale up.
