[Beijing, China, June 6, 2021] Television has been around for almost 100 years by now, and over that time it has broadened minds around the world, bringing us to new places and introducing us to new people every day. Over the years, we have also watched as image and audio quality improved from 480i to 1080p, then further on to 1K and 4K resolution, and from single-channel to surround and then to stereo. Now, new smart devices like computers, mobile phones, and tablets, are pushing the entertainment industry to new heights. Advancements in computing, connectivity, and interaction are turning TVs from boxes to large smart screens and 8K is marking a new era of innovation.
For example, on Jun 6, China Media Group (CMG) announced its new "Beijing Terminal" station that would be the home of its upcoming "Beijing2022: It's snowtime" campaign. This exciting new programing will cover the 2022 Beijing Winter Olympics and Paralympics using innovative "5G + 4K/8K + AI" solutions to deliver 8K ultra high-definition (UHD) that CMG promises will give viewers from around the world never-before-seen Olympic viewing experiences.

So What Are 8K Services?
Most people know 8K as the newest TV resolution standard, but 8K refers to more than just higher resolution. It also represents an overall upgrade in video services. 8K can be used for live-casting important events and ordering on-demand programing as well as a whole host of home smart screen and immersive gaming experiences. In particular, 8K delivers:
Richer details: With 7680 x 4340 pixels (16 times that of full high-definition) and a 120 Hz frame rate (4 times that of FHD), 8K UHD creates images that are noticeably different to the human eye. 8K UHD can achieve 64 times more detail with millisecond refresh rates.
Brighter colors: With up to 12-bit color depth (currently 10-bit), 8K combines HDR Vivid and BT.2020-enhanced WDR, and blows SDR's traditional 8-bit color depth out of the water. This improves the color gamut coverage by 72% and luminance by 40 times, delivering a richer color depth for more nuanced images.
True-to-life experiences: In addition to the ultimate 2D display, 8K is also pushing the boundaries of 3D. 8K-chip manufacturer HiSilicon, for example, is currently working with content producers to create 360-degree, panoramic, 3D videos that allow viewers to see 3D content from any viewing angle on a 2D screen. This immersive 8K visual experience when combined with 3D audio creates a truly immersive audiovisual feast.
HiSilicon 8K Chips: A Decade of Innovation
HiSilicon in particular has been a pioneer in the chip industry, spending the last decade laying the groundwork for the chips that are powering this new 8K TV revolution.
As a key contributor to previous next-generation audio and video standards such as AVS3 and HDRVivid, it has already had a hand in the big-screen audio and video entertainment experiences we are used to today, such as multi-view videos. In recent years, HiSilicon has also started building AI directly into its chips and has developed many cutting-edge algorithms including the 8K supercomposition algorithm based on generative adversarial network (GAN), the SDR2HDR algorithm based on deep learning, the motion estimation and motion compensation (MEMC) algorithm, and other 3D sound effect algorithms.
Some of the highlights we've seen from HiSilicon include a wide array of 8K standards such as:
AVS3: The first 8K/VR codec standard, providing 36% higher codec performance than HEVC/H.265.
HDR Vivid: A leading HDR standard that delivers extraordinary visual experience and brightness adaptation.
ChinaDRM: Based on proprietary core patents and has become an industry standard.
New application interfaces: Next-generation high-speed multimedia interfaces and 8K large-screen P2P interfaces.
HiSilicon's powerful performance, reliability, and chip ecosystem have become the mainstay of the TV market. 2021 will be the first year of 8K, with the CMG's 2022 Winter Olympics 8K project testing the limits of UHD production and broadcasting technologies next year. We look forward to seeing what 8K content producers will make using HiSilicon in the upcoming year!
