Telepresnce Solutions and SVC
This document discusses the future of telepresence and how new technologies can make it more accessible. It proposes that:
1. Using scalable video coding (SVC) and a video routing unit (VRU) can replace traditional MCUs, enabling near-zero delay, high quality experiences without quality loss from multiple encodings.
2. SVC allows co-existence of low-end and high-end systems by adapting video quality based on available bandwidth.
3. The VRU architecture is simpler and more scalable than MCUs. Combined with SVC and standard hardware, these technologies can solve long-standing videoconferencing problems and make telepresence affordable and ubiquitous.
Next generation video compression
Requiring only half the bitrate of its predecessor, the new standard – HEVC or H.265 – will significantly reduce the need for bandwidth and expensive, limited spectrum. HEVC (H.265) will enable the launch of new video services and in particular ultra HD television (UHDTV).
State-of-the-art video compression techniques – HEVC/H.265 – can reduce the size of raw video by a factor of about 100 without any noticeable reduction in visual quality. With estimates indicating that compressed real-time video accounts for more than 50 percent of current network traffic, and this figure is set to rise to 90 percent within a few years, HEVC/H.265 will be a welcome relief for network operators.
New services, devices and changing viewing patterns are among the factors contributing to the growth in video traffic as people watch more and more traditional TV and video-streaming services on their mobile devices.
Ericsson has been heavily involved in the standardization of HEVC since it began in 2010, and this Ericsson Review article highlights some of the contributions that have led to the compression efficiency offered by HEVC.

NEXT GENERATION BROADCASTING TECHNOLOGY
Ultra HD, or UHDTV, is the next generation television standard beyond HDTV and 4K. It provides viewers with a superior sense of reality through higher resolution, higher frame rates, more colors, and higher dynamic range. Key aspects of UHDTV include 8K resolution displays and broadcasting, wide color gamut, high dynamic range, and next-generation 22.2 channel surround sound. Standardization efforts are underway to define UHDTV formats, compression, transport, and end-to-end solutions. Early adopters like Japan and Korea are conducting trials of 8K satellite and terrestrial broadcasting using HEVC video coding and DVB transmission standards.

ABU tech 259 Q3 2014 UHDTV
Korea was the first country to broadcast UHDTV (Ultra High Definition Television) over DVB-T2 starting in 2012 at 30fps. By 2014, major Korean broadcasters were transmitting their own UHDTV programs at 60fps over DVB-T2 to cover the Seoul metropolitan area. This case study discusses the technical challenges of delivering UHDTV over terrestrial transmission in Seoul, such as achieving 60fps live transmission, providing coverage across Seoul's single frequency network, and targeting both rooftop and indoor reception within a 6MHz bandwidth. The use of HEVC encoding and improvements to it will be key to meeting these challenges at data rates below 20Mbps needed for error-free indoor reception.

Patrick Worfolk, Senior Vice President and CTO of Synaptics, presents the “Enabling Visual AI at the Edge: From Surveillance Cameras to People Counters" tutorial at the May 2021 Embedded Vision Summit.
New AI-at-the-edge processors with improved efficiencies and flexibility are unleashing a huge opportunity to democratize computer vision broadly across all markets, enabling edge AI devices with small, low-cost, low-power cameras. Synaptics has embarked on a roadmap of edge-AI DNN processors targeted at a range of real-time computer vision and multimedia applications. These span from enhancing the image quality of a high-resolution camera’s output using Synaptics' VS680 multi-TOPS processor to performing computer vision in battery-powered devices at lower resolution using the company's Katana Edge-AI SoC.
In this talk, Worfolk shows how these edge AI SoCs can be used to:
• Achieve exceptional color video in very low light conditions
• De-noise and distortion-correct both 2D and 3D imagery from a time-of-flight depth camera that images through a smartphone OLED display
• Perform super-resolution enhancement of high-resolution video imagery, and
• Recognize objects using lower-resolution sensors under battery power.STREAMING and BROADCASTING CHEAT SHEET

Enensys -Content Repurposing for Mobile TV Networks
The document discusses content repurposing for mobile TV networks. It describes the need to adapt existing TV content from different formats to fit on small mobile screens. The challenges of transcoding content from standard definition to mobile TV formats are discussed. Different techniques and algorithms must be used to optimize the transcoding process and integrate content smoothly into mobile TV systems. The source TV content comes from satellite, cable or terrestrial networks in digital formats like MPEG-2. The target is mobile TV, which has size constraints of 2-5 inch screens and lower resolutions than standard TV. Content must be adapted to meet these constraints while preserving quality.

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.

Introduction to 8 k
- 1. INTRODUCTION TO 8K Submitted By- Pratiksha Pandey 14cs033 Submitted To- Mr. Anubhav Saxena (Assistant Professor)
- 2. What is 8K Resolution means?
- 3. 8K resolution, or 8K UHD, is the current highest ultra high definition television (UHDTV) resolution in digital television and digital cinematography. 8K refers to the horizontal resolution of 7,680 pixels, forming the total image dimensions of (7680×4320), otherwise known as 4320p
- 4. PIXEL • DEFINITION- In digital imaging, a pixel is a smallest controllable elements of a picture (Building block of a picture). • PIXEL DENSITY- Number of pixels in certain space.Usually measured in PPI. • PPI(Pixel Per Inch)- Number of pixel per inch.
- 6. COMAPRISON HDTV TOTAL PIXELS=2,000,000 PIXELS PPI=102 PIXEL PER INC IPHONE TOTAL PIXEL=700,000 PIXELS PPI=326 PIXEL PER INC
- 7. RESOLUTION • DEFINITION- Number of distinct pixels in each dimention that can Be displayed. • AVAILABLE RESOLUTIONS *2K (1920 X 1080) *4K (3840 X 2160) *8K (7680 X 4320)
- 9. 4K/8K TECHNOLOGY AND NEW NETWORKS
- 10. Obstacles to 8K Implementation As great as it seems, especially for professional applications, targeting the consumer market is not that easy. With billions of dollars having already been invested by broadcasters, manufacturers, and consumers on currently available HDTV broadcast technology, 4K TVs, and source devices, and with 4K TV broadcasting just now getting off the ground, widespread availability and use of 8K is a way off. However, behind the scenes, preparations are being made for a consumer-targeted 8K landscape.
- 11. 8K and TV Broadcasting It can be done by Super Hi-Vision video and broadcast format. This broadcast format is not only intended to display 8K resolution video but can also transfer up to 22.2 channels of audio. The 22.2 channels of audio can be used to accommodate any current or forthcoming surround sound format, as well as providing a way to supply multiple language audio tracks - which would make universal worldwide TV broadcasting more practical.
- 12. 8K and Connectivity In order to accommodate the bandwidth and transfer speed requirements for 8K, physical connectivity for forthcoming TVs and source devices have to be upgraded. To prepare for this, an upgraded version of HDMI (ver 2.1) has been made available to manufacturers that can be incorporated not just in TVs and source devices but switchers, splitters, and extenders.
- 13. FUTURE OF 8K TELEMEDICINE *Recording of surgeries and medical diagnostic processes for educational purposes.
- 14. SECURITY AND MONITORING issue: face recognition in a crowd at airports, train stations and during mass events (e.g. stadiums) Many details on single 8K frame – the powerful source for image processing Useful for police, border services and others security units
- 15. CAD/CAM PROJECTS Automotive design Design and digital visualisatiom of 3D car models Tests of safety, aerodynamics and ergonomic solutions Architecture and urban planning Design and visualisation of buildings and engineering constructions models Tests of ergonomic and functionality as well as strength and safety of constructions
- 17. SUMMARY Regardless of the ability to transmit and display 33- million pixel 8K resolution images on a TV screen, the key to its acceptance will be affordability and the ability to provide viewers with actual native 8K content. Unless TV and movie studios produce or remaster content in 8K and have distribution outlets (streaming, broadcast, or a physical medium), there will be no real incentive for consumers to once-again dig into wallets and spend their cash on a new 8K TV, no matter the price.
- 18. THANK YOU
