Live 4Kp60 Optimized Encoding with Beamr CABR and NVIDIA Holoscan for Media

This year at IBC 2024 in Amsterdam, we are excited to demonstrate Live 4K p60 optimized streaming with our Content-Adaptive Bitrate (CABR) technology on NVIDIA Holoscan for Media, a software-defined, AI-enabled platform that allows live video pipelines to run on the same infrastructure as AI. Using the CABR GStreamer plugin, premiered at the NAB Show earlier this year, we now support live, quality-driven optimized streaming for 4Kp60 video content.

It is no secret that savvy viewers are coming to expect the high-quality experience of 4K Ultra-High-Definition streamed at 60 frames per second for premium events. What started with a drizzle a few years back has become the high end norm for recent events such as the 2024 Olympics, where techies were sharing insights on where it could be accessed.

Given the fact that 4K means a whopping four times the pixels compared to full HD resolution, keeping up with live encoding of 4K at 60 fps can be quite challenging, and can also result in bitrates that are too high to manage.

One possible solution for broadcasters is to encode and transmit at 1080p and rely on the constantly improving upscalers available on TVs to provide the 4K experience, but this of course means they cannot control the user experience. A better solution is to have a platform that is super fast, and can create live 4Kp60 encodes, which combine excellent quality with an optimization process that minimizes the required bitrate for transmission.

Comparison of 4K Live video before and after optimization

Beamr CABR on Holoscan for Media offers exactly that, by combining the fast data buses and easy-to-use architecture of Holoscan for Media with Beamr hardware-accelerated, quality-driven optimized AV1 encoding. Together, it is possible to stream super efficient, 4K, lower bitrate encodes at top notch quality.

Content Adaptive Bitrate encoding, or CABR, is Beamr’s patented and award-winning technology that uses a quality measure to select the best candidate with the lowest bitrate and the same perceptual quality as a reference frame. In other words, users can enjoy 30-50% lower bitrate, faster delivery of files or live video streams and improved user experience – all with exactly the same quality as the original video.

In order to achieve aggressive bitrates which are feasible for broadcast of live events, we configure the system to use AV1 encoding. The advanced AV1 format has been around since 2018. However, its full potential has not been fully realized by many players in the video arena. AV1 is raising the bar significantly in comparison to previous modern codecs, such as AVC (H.264) or HEVC (H.265), in terms of efficiency, performance with GPUs and high quality for real-time video. When combined with CABR – AV1 is offering up even more. According to our tests, AV1 can reduce data by 50% compared to AVC and by 30% compared to HEVC. We also showed that CABR optimized AV1 is beneficial for machine learning tasks.

Putting all three of these technologies together, namely deploying Holoscan for Media with the Beamr CABR solution inside, which in turn is using NVIDIA’s hardware-accelerated AV1 encoder, provides a platform that offers spectacular benefits. With the rise in demand for high-quality live streaming at high resolution, high fps and manageable bitrates, while keeping an eye on the encoding costs – this solution is definitely an interesting prospect for companies looking to boost their streaming workflows.

How to deal with the tension on the mobile network – part 2 (VIDEO Interview)

In late July, I reported on the “news” that Verizon was throttling video traffic for some users. As usual, the facts around this seemingly punitive act were not fully understood, which triggered this blog post.

At IBC last month (September 2017), I was interviewed by RapidTV where much of the conversation was around the Apple news of their support for HEVC across the device ecosystem running iOS 11 and High Sierra. As I was reviewing this interview, it seemed natural to publish it as a follow up to the original post.

There is no doubt that mobile operators are under pressure as a result of the network crushing video traffic they are being forced to deliver. But the good news is that for those operators who adopt HEVC, they are going to enjoy significant bitrate efficiencies, possibly as high as 50%. And for many services, though they will chose to take some savings, this means they’ll be able to upgrade their resolutions to full 1080p while simultaneously improving the video quality they are delivering.

I hope you find this video insightful. Our team has a very simple evaluation offer to discuss with all qualified video services and video distributors. Just send an email to sales@beamr.com and we’ll get in touch with the details.

Beamr Video Optimizes Videos and. . . T-shirts?

As we were getting ready for IBC a few weeks ago, we started thinking about how making the visit to our booth more special. The idea of giving away T-shirts came up, and since we didn’t think people would be happy to go around wearing a Beamr Video logo, we decided to put a nice slogan on them: “Network Friendly”. This is the essence of what Beamr Video does: It reduces the bitrate of videos without compromising their quality, resulting in video files that are more “network friendly” – they don’t clog the network as much as regular videos, and provide a better streaming experience to the end user. So who wouldn’t want to wear a T-shirt saying that they’re Network Friendly? It’s a very friendly statement and a conversation starter…

But now we faced a problem: We estimated that we could give away 200 T-shirts at the show, but we had no room to store this many T-shirts in our booth – only a small storage space was provided by the organizers. And, shipping the T-shirts to the show would cost us a lot of money. So we thought: How can we reduce the storage requirements and the delivery costs of our T-shirts? And then it hit us: Optimization! This is what we must do to the T-shirts! In the same way that Beamr Video optimizes the videos to reduce storage and delivery costs, we would do the same by compressing our T-shirts.

Immediately we started looking for vendors of compressed T-shirts that could deliver the goods in time for IBC. Luckily we encountered GoTeez, that said the T-shirts would be ready on time. How is a compressed T-shirt even made? Check out this video.

So: Problem solved! And, we now had the perfect pitch for IBC. This is what we told every visitor after explaining the benefits of Beamr Video, and just before they left the booth:
“Oh, and one more thing: We also compress T-shirts! We had a problem of storage and delivery costs in bringing the T-shirts to the show, so we optimized them for delivery – which is exactly what Beamr Video does to your videos. And just like Beamr Video, the T-shirts are fully standard, and you can use a standard “decoder” to de-compress them: Just open the packaging, unfold the shirt and iron it using a standard iron, and you have your full-sized T-shirt!”. The result: Everyone left the booth with a big smile, and we were confident that our message came across clearly…

Hottest Trends From IBC 2014 in Amsterdam

We’re back after 5 intensive days at IBC 2014 in Amsterdam, where we presented Beamr Video 2.0 to over 200 potential customers. After catching our breath, we are now ready to share some of our insights from the show.

IBC 2014

First and foremost: Everyone and everything is moving to IP. Whether you’re a TV station, cable or satellite operator, content producer or rights owner, you know that IP-based over-the-top delivery of your content will become a growing part of your business, and will eventually take over traditional delivery methods. The reason is obvious: Consumers today are connected through a variety of devices, such as smartphones, phablets, tablets and laptops, and they expect to have access to your content anytime and anywhere. Every major TV service operator, whether it is cable, satellite or IPTV has some form of “TV Everywhere” service, where subscribers can access content without being tied to their set-top box at home. And vendors at IBC had a large variety of solutions for OTT video delivery, including workflow, transcoding, content management, delivery, conditional access and monetization.

Another important trend that ties into the move to IP is the move to the cloud. Companies are offering solutions for “cloud-based everything” – from content editing to management to transcoding to DVR. In fact, our feeling was that today you can become a virtual TV operator in the cloud without owning any equipment other than a camera and an Internet connection. All you need to do is to produce good content and start counting the revenues (we wish it was that easy…).

On the more technical side, we saw MPEG-DASH gaining more ground as the standard for media streaming services. On the codecs front, HEVC has emerged as the dominant next-generation codec, with many companies showing offline and real-time encoders, chips, set-top boxes and smart TVs that support the new standard. Google’s VP9, which at CES seemed like a viable competitor to HEVC, being a royalty-free, open source codec (including royalty-free silicon IP cores for chips), was hardly noticeable at IBC, and the general feeling was that HEVC is the only way to go. HEVC is being introduced first to solve a real issue: Delivery of Ultra-HD (4K) content over the Internet. But as more and more capture and playback devices support HEVC, it is likely that it will also be used for HD resolutions and below.

Speaking of Ultra-HD, you can imagine that it was one of the main themes of the show, but it seems that the industry has not yet decided on the set of parameters that will be used for initial deployments: Frame rate, bit depth, and color space are still in the open. Increasing each of these parameters improves visual quality but also increases the overall bitrate, which is already quite high due to the 4x increase in pixel count over HD. Obviously if you use Beamr Video you can get the bitrate down again, but that will be the subject of another post..

Cutting Bitrate by 50% Just Became a Reality

It is with great joy and excitement that we announce the launch of Beamr 2.0 today. It was just one short year ago that we launched Beamr Video and set out to reduce the bitrate of any H.264 or HEVC video stream by up to fifty percent, enabling a smoother streaming experience with reduced buffering and a faster stream start. So what’s new in Beamr 2.0?

Beamr Video 2.0 now offers a web dashboard and multi-core processing capabilities. The dashboard lets you easily monitor and control the video optimization process. With the dashboard, users can view the progress and optimization parameters used for each job, check the overall and average bitrate savings across all jobs, and monitor the system resource utilization for CPU and memory.

The multi-core processing capabilities enables the most efficient usage of computing resources. Once a user selects the number of cores allocated for processing, the tool divides the video file into multiple segments and processes them in tandem on different cores, ensuring the maximum performance and fastest turn-around times for a user’s video optimization jobs. Once the optimization is complete, Beamr Video 2.0 “stitches” the segments back together to create the output file.

Visit Us at IBC in Amsterdam, September 12-16

Beamr Video is heading to IBC in Amsterdam to show off some demos, meet our customers, say hello to old friends, and give out compressed T-shirts.

The first demo we’ll be showing off will be a split-screen video demo displayed on a 4K screen. One half of the screen shows the original video, and the other half shows the video after Beamr Video optimization, with 30-50% of the bitrate shaved off. Can you tell which is which? You’ll have 30 seconds before we reveal the answer… .

In the second demo you’ll see the Beamr Video software in action. This is where you get to see how the software runs, what parameters can be tweaked, and what are the results of the optimization. Here’s an added bonus – if you bring your own video, we’ll optimize it on the spot, and you’ll travel lighter when you go back home with it…

See you at IBC 2014, September 12-16 at the Amsterdam RAI, Hall 3, Booth B20.
