NAB 2024 Show Report – Part 2 – Round-up

We published Part 1 of our NAB 2024 report on 8K developments last week and in part 2 we cover the shorter items. You can also see a number of short vlog posts on YouTube here.

Apantac is a developer of interfaces and AV hardware from Portland, Oregon, and was at the show highlighting its range. The author’s attention was caught by the range of different modules for the Intel developed SDM architecture . It has 8K switches and splitters as well as a Crescent HDMI testers, analyzers and signal generators.

Ateme told us that it had been responsible for encoding and processing the 200+ 3D titles that were released with the Apple Vision Pro. There was a demo using the Apple headsets, the first time that the author had had the chance to try it as it is not yet available outside the US. The tracking of the Apple headset was impressive.

Visitors to the 8K Association booth from the ATSC were very keen to point out that the ATSC 3.0 system could be used to support up to 50Mbps for a single channel or to 100Mbps for dual channels which is very suitable for supporting 8K content.

BlueDot is a start-up from Korea that is offering technology and services for AI-based upscaling. The algorithms are based on their own training systems and the firm told us that it can upscale to 8K based on its database of over a million video samples. The company has patents on some aspects of pre-processing, The firm supplies software and can support hardware makers.

Brompton is known for the high quality of its LED processors and it previewed a new 8K processor that iut will release later this year. The box can accept four 4K inputs or one 8K and outputs to either 10Gbps or 1Gbps distributors using UTP. Inputs are HDMI, DisplayPort 2.1 or 12G SDI. Brompton told us that it is waiting for DP2.1 devices to finalize the product. The processor is said to be 20X more powerful than the predecessor and will allow extremely high frame rates. Brompton told us that Intel had been a key partner in the development of the unit.

8K Association member BZBGear was at the show to highlight its full range of products for 8K support.

Canon was showing the stereo 3D lenses that it has developed for its mirrorless R5 and R5C 8K cameras. It also had a number of 8K stereo product concept designs that it is considering for future production.

DJI was promoting. both the Ronin 4D 8K camera which has a ‘two box’ design with the sensor and lens separate from the rest of the body. The sensor and lens are controlled by an integrated gimbal to make the unit very handy for hand-holding of 8K content capture. The firm was also getting a lot of interest in its Inspire 3 8K drone. We heard at the show that the firm is suffering from restrictions on the use of its products because of the poor trade relationship between the US and China.

Evertz is an Emmy-winning Canadian developer of broadcast equipment which told us that it has been developing its ST.2110 capabilities and can supply an 8K JPEG XS encoder system.

The Fraunhofer HHI was at the show to promote its developments in JPEG XS, which it co-developed with Intopix, It highlighted its software SDK and also its hardware designs. The group also explained to us the Reference Picture Resampling feature that exploits OpenGOP technology. That’s a topic that we plan to return to on the 8K Association website.

The Fraunhofer HHI showed how the Reference Picture Resampling feature in VVC reduces the glitches and artifacts when video resolution is switched during streaming.

Insta360 was showing its new 8K 360 degree camera which is available immediately for $499 in the US and which can also support 4K 180 degree video. When used as a still camera, it has a 72 megapixel sensor configuration.

Kinefinity was showing a new 8K camera prototype that can be used foir live production as it has SDI-outputs. It has a new sensor that supports ‘DCI’ 8K at 66fps and up to 130fps in DCI 4K. Dynamic range is said to be 14 stops and it has a new 0.7″ microOLED 1080P EVF., THere will be a range of lens mounts. The firm also said that it would release a new version of its KineOS OS, V8.0 in July. The new software will support RAW capture up to 4K 75P initially and 4K 120P later. No pricing has been announced for the new camera although the firm said that it will ‘not be too much different’ froom the current Mavo. Delivery will be around July or August. There’s a YouTube video interview here.

Lilliput makes small monitors for field monitoring and it had products advertised as 8K, but, like other broadcast monitors (including Konvision) that meant that the monitors would accept 8K inputs, but did not have 8K panels and used four 4K inputs.

Main Concept GmbH develops codecs but at the show was highlighting its advert insertion technology and its easy video API which gives access to features in its encoders and was not promoting its 8K technology specifically.

The Media Coding Industry Forum (MC-IF) was at the show and we asked how the group fits into the industry. We heard that its aim is to support the adoption and use of MPEG standards. The MPEG organisation is responsible for developing standards but once they are finished, their job is over (apart from revisions and fixes). The MC-IF acts to promote and commercialize the standards to try to achieve wider adoption.

Novastar was showing its MX6000 Pro and MX2000 processors which both support 8K LED video walls at up to 8K60P via HDMI 2,1 and DisplayPort 1.4. The company told us that it is working on an integrated ST.2110 receiver and hopes to have it working by the year end, The connections to the LED cabinets is via fiber which, the firm told us, is no longer the cost penalty that it once was. Staff said that not only are control rooms and virtual production installations popular as applications, but it also sees demand in TV studios. These often use a single 8K display surface for control and content management, with different displays showing windowed parts of the surface.Aja was showing its 8K Corvid and Kona cards as well as its Aja vidoe analyzer which also supports 8K.

Pixelhue is a company that makes equipment for control of live video content and event control and had an impressive console that can support up to 8K signals. It is fitted with a nice looking 32:9 43.8″ LCD that makes control simpler and the console can accept HDMI, DisplayPort, SID and ST.2110 inputs. The console can support up to 48 4K inputs or 16 4K outputs.

Pixelvue’s impressive console supports 8K

We have previously reported on Synamedia when it ran some projects with BT Sport in 8K. At NAB, the firm confirmed that it can now offer live encoding of 8K with VVC. At the show it was also highlighting the pVMAF metric which is its version of the VMAF measurement system developed by Netflix, the Video Multimethod Assessment Fusion. Synamedia told us that it sees VMAF as significantly closer to the perceptual quality than other methods such as PSNR and SSIM.

LCEVC is a standard developed by V-Nova and uses an enhancement layer concept. At the moment this is mainly being used to allow content to be delivered in FullHD with additional layers to support higher resolution. At the show it was demonstrating a Hisense TV that had been enabled with LCEVC on top of VVC using an existing codec chip. The firm told us that it is seeing a lot of interest in LCEVC and potential clients are looking to support TVs up to three years old. (Other codec developers said that they could see the advantage of LCEVC where there was a desire to support older installed bases, but in new installations, it seems better to use the bits used by the LCEVC enhancement layer to improve the core signal).

Video Clarity is a specialist company that makes tools to characterize and assess codecs and encoders. Broadcasters and streamers invest a lot in encoding technology and tools and the firm provides hardware and software tools that can allow comparison (both in terms of data and by showing side by side performance) of performance. The firm can support 8K video.  It also has tools for real time audio and video quality. At the show it was highlighting new facilities for HDR video quality analysis.   

Vindral of Sweden collaborated with AMD to create an 8K AV1 10 bit HDR live stream with ‘ultra-low’ latency and claimed to be in high quality. The demonstration was powered by AMD’s Alveo MA35D media acceleration card, shown at NAB last year.  Vindral is working with NETINT Technologies on reducing latency and allowing synchronization to allow delays of less than 100ms. In some applications, the firm said, synchronization of different content delivery systems is at least as important, and sometimes more important than latency alone.
