The pandemic has accelerated efforts that were already underway to expand telemedicine. To avoid the spread of the coronavirus through in-person visits, doctors and patients turned to virtual visits as a safe and convenient way to ensure doctors’ and patients’ health. Telehealth, however, will likely continue to be an important health care service in our post-pandemic lives. The forced adoption of virtual doctor visits has shown how useful e-visits can be for routine check-ups. In fact, a recent study conducted by the American Medical Association concluded that 24% of health care office visits and outpatient volume could be delivered virtually…

The electric feeling of a live sports event is infectious. The exhilaration of a hard-fought victory or the anguish of defeat all stream through. Broadcasters of sporting events capitalize on that excitement, and trying to replicate an in-stadium experience for fans streaming from home can be a really lucrative opportunity. How we consume sports content has evolved from passively watching broadcasts with long delays to real-time interactive streaming. When done right, streaming live sports can elevate fans from simple spectators to fully involved participants. For this to happen, though, everything has to flow naturally. Let’s examine the recent history…

Effectively delivering live streaming video is hard. Lots of pieces have to be put together which means connections can drop in plenty of places if everything doesn’t fit correctly. A very big piece of the puzzle is the infrastructure behind transporting a video. You need to find a way to connect the video that is being broadcast with a subscriber who will watch it. Up until now, the best option to send a live video over the internet was a content delivery network (CDN). The three most important features for live video streaming are: Real-time latencyMulti-directional streamsData synchronizationHowever, it…

As addressable advertising — that is, the ability to present different ads to different households while they’re watching the same program — gains momentum in the premium video streaming market, providers of real-time video experiences need to be able to support an approach to instantaneous server-side ad insertions that squares with their ultra-low latency mandates. This important monetization opportunity can be enabled by an experience delivery network (XDN) architecture that supports interactive real-time video applications at massive scale. By virtue of how it orchestrates multidirectional delivery of video streams, such an architecture is inherently optimized to enable real-time dynamic ad insertion…

Some have characterized WebRTC as the gateway to a communication promised land that can connect people virtually anywhere in real time. Indeed, if you want to deliver real-time communications and low-latency video streaming in the browser, WebRTC is currently your only widely supported option. The challenge has been, as developers in this space know only too well, that WebRTC, by itself, doesn’t scale. To truly scale WebRTC applications, you have to leverage topologies designed to extend its capabilities. Each of these topologies has its pros and cons, of course, and which is best for any given application depends on…

As the battle against online video piracy intensifies, license holders need better approaches to forensic watermarking that can accelerate action against theft of live content, including content streamed in real time, without creating vulnerabilities to pirates’ countermeasures. Given how hard it is to battle theft of live content streamed at multi-second latencies using current watermarking techniques, the idea that watermarking might be used to take effective action against theft of content streamed at 200-400ms latencies might seem farfetched. But, as shall be seen, it turns out that a next generation CDN, better described as an Experience Delivery Network (XDN), that…

By its nature, video streaming is a quality-sensitive application, especially when it comes to live video. Maintaining a consistent stream is very important. Every video and audio frame has the potential to include key information so mishandling those frames could be very detrimental to the user experience. In the real world, when things go wrong they tend to happen at the very worst time like the last minute of a big match between two undefeated teams. Any problem at that point can have dire consequences with upset users turning to social media to vent their frustrations and causing permanent damage…

There’s no better clue to the deficiencies of a vendor’s solution than a claim that what a competitor is doing can’t be done. It’s one thing for a supplier to say the technology their solution employs is better on the merits. Claiming that they’ve chosen their technology because a better idea that’s proving itself in the marketplace doesn’t work is simply to admit they can’t do it themselves. 1. Saying WebRTC can’t be scaled only proves you can’t do it This happens a lot in discussions about whether it’s…

When it comes to deciding between low latency HLS and WebRTC, which protocol delivers the best live streaming experience? Since the protocol determines how quickly the encoded video data will be transported across an internet connection, the decision of which one to use is very important. Wowza recently published an article that contains misinformation about WebRTC and low latency HLS. While correctly establishing that WebRTC is the only way to provide real-time latency they repeated some common misconceptions as well, especially the often repeated myth – fully debunked by Red5 Pro and others – that WebRTC does not scale. After further analysis,…

What is the best approach to setting up your testing environment? You want to conduct a full test of all your features, confirm expected behavior, and identify any bugs before releasing your application or updates live to your consumers. Poor testing can lead to a poor user experience which can have a disastrous impact on the longevity and profitability of your application. However, if you already have an application running, you can’t just shut it off every time you want to add a new feature. This is where a Blue-Green deployment comes into play. The structure for a Blue-Green…

The next stage in video streaming revolves around increasing access to 4K–Ultra High Definition–video. Right now, the major obstacles to implementing 4k on a wide scale is the large amount of data it consumes and the delay it takes to send it. Currently, the codec in widest use is H.264–also known as AVC. Given H.264’s high compression ratios, it is not well suited for the high bandwidth demands of 4K streaming. In order to meet this challenge, a variety of next-gen codecs have been released. Though some of these next-gen codecs are stable, many…
