COMPRESSION, WHY, WHAT AND COMPROMISES Authors Hightower, Paul Publisher International Foundation for Telemetering Journal International Telemetering Conference Proceedings Rights Copyright © held by the author; distribution rights International Foundation for Telemetering Download date 06/10/2021 11:41:22 Link to Item http://hdl.handle.net/10150/631710 COMPRESSION, WHY, WHAT AND COMPROMISES Paul Hightower Instrumentation Technology Systems Northridge, CA 91324 [email protected] ABSTRACT Each 1080 video frame requires 6.2 MB of storage; archiving a one minute clip requires 22GB. Playing a 1080p/60 video requires sustained rates of 400 MB/S. These storage and transport parameters pose major technical and cost hurdles. Even the latest technologies would only support one channel of such video. Content creators needed a solution to these road blocks to enable them to deliver video to viewers and monetize efforts. Over the past 30 years a pyramid of techniques have been developed to provide ever increasing compression efficiency. These techniques make it possible to deliver movies on Blu-ray disks, over Wi-Fi and Ethernet. However, there are tradeoffs. Compression introduces latency, image errors and resolution loss. The exact effect may be different from image to image. BER may result the total loss of strings of frames. We will explore these effects and how they impact test quality and reduce the benefits that HD cameras/lenses bring telemetry. INTRODUCTION Over the past 15 years we have all become accustomed to having television, computers and other video streaming devices show us video in high definition. It has become so commonplace that our community nearly insists that it be brought to the telemetry and test community so that better imagery can be used to better observe and model systems behaviors. -

Image Resolution
Image resolution When printing photographs and similar types of image, the size of the file will determine how large the picture can be printed whilst maintaining acceptable quality. This document provides a guide which should help you to judge whether a particular image will reproduce well at the size you want. What is resolution? A digital photograph is made up of a number of discrete picture elements, known as “pixels”. We can see these elements if we magnify an image on the screen (see right). Because the number of pixels in the image is fixed, the bigger we print the image, then the bigger the pixels will be. If we print the image too big, then the pixels will be visible to the naked eye and the image will appear to be poor quality. Let’s take as an example an image from a “5 megapixel” digital camera. Typically this camera at its maximum quality setting will produce images which are 2592 x 1944 pixels. (If we multiply these two figures, we get 5,038,848 pixels, which approximately equates to 5 million pixels/5 megapixels.) Printing this image at various sizes, we can calculate the number of pixels per inch, more commonly referred to as dots per inch (dpi). Just note that this measure is dependent on the image being printed, it is unrelated to the resolution of the printer, which is also expressed in dpi. Original image size 2592 x 1944 pixels Small format (up to A3) When printing images onto A4 or A3 pages, aim for 300dpi if at all Print size (inches) 8 x 6 16 x 12 24 x 16 32 x 24 possible. -

There are a variety of resolutions that are claimed to be 4K, but in general 4K offers four times the resolution of standard 1080p HD video. A number of names or acronyms for 4K are being used across the industry including Quad Full HD (QFHD), Ultra HD or UHD and 4K2K. For the purposes of this report, the term 4K will be used. ● These terms all refer to the same resolution: 3,840 by 2,160. ● The EBU has defined 3,840 by 2,160 as UHD-1. -

Impact of Adaptation Dimensions on Video Quality
Impact of Adaptation Dimensions on Video Quality Jens Brandt and Lars Wolf Institute of Operating Systems and Computer Networks (IBR), Technische Universitat¨ Braunschweig, Germany [email protected] Abstract—The number and types of mobile devices which well as the network conditions, may vary more often over time are capable of presenting digital video streams is increasing compared to static devices. Thus, the experience of watching constantly. In most cases the devices are trade-offs between video streams on mobile devices differs to a great extent from powerful all-purpose computers and small mobile devices which are ubiquitously available and range from cellular phones to those scenarios related to static displays usually found in the notebooks. This great heterogeneity of mobile devices makes area of home entertainment. For sequences from soccer games video streaming to such devices a challenging task for content McCarthy et al. observed that potential users preferred lower providers. Each single device has its own capabilities and indi- frame rates but higher detail resolution on mobile devices [2]. vidual requirements, which need to be considered when sending For other genres similar findings were presented for scalable a video stream to it. Thus, to support a great range of different devices, the video streams need to be adapted to the requirements video coding by Eichhorn and Ni in [3]. Besides concentration of each device. To get an idea of how different adaptation methods solely on the temporal resolution of a video stream, in our may affect the experience of users watching a streamed video on a work we additionally investigated the effect of adapting the mobile device, we inspect the influence of three major adaptation spatial and the detail resolution as well. -
What the Heck Is HDTV?
05_096734 ch01.qxp 12/4/06 10:58 PM Page 9 Chapter 1 What the Heck Is HDTV? In This Chapter ᮣ Understanding the acronyms ᮣ Transmitting from ATSC to the world ᮣ Going wide ᮣ Avoiding the pitfalls ince the transition to color TV in the 1950s and ’60s, nothing — nothing!! — Shas had as much impact on the TV world as HDTV (high-definition TV) and digital TV. That’s right. TV is going digital, following in the footsteps of, well, everything. We’re in the early days of this transition to a digital TV world (a lot of TV programming is still all-analog, for example), and this stage of the game can be confusing. In this chapter, we alleviate HDTV anxiety by telling you what you need to know about HDTV, ATSC, DTV, and a bunch of other acronyms and tech terms. We also tell you why you’d want to know these terms and concepts, how great HDTV is, and what an improvement it is over today’s analog TV (as you can see when you tune in to HDTV). Finally, we guide you through the confusing back alleys of HDTV and digital TV, making sure you know what’s HDTV and what’s not. Almost everyone involved with HDTV has noticed that consumer interest is incredibly high with all things HDTV! As a result, a lot of device makers and other manufacturers are trying to cash in on the action by saying their products are “HDTV” (whenCOPYRIGHTED they are not) or talking about MATERIAL such things as “HDTV-compatible” when it might be meaningless (like on a surge protector/electrical plug strip). -
Video Terminology Video Standards Progressive Vs
VIDEO TERMINOLOGY VIDEO STANDARDS 1. NTSC - 525 Scanlines/frame rate - 30fps North & Central America, Phillipines & Taiwan . NTSC J - Japan has a darker black 2. PAL - 625 scanlines 25 fps Europe, Scandinavia parts of Asia, Pacific & South Africa. PAL in Brazil is 30fps and PAL colours 3. SECAM France Russia Middle East and North Africa PROGRESSIVE VS INTERLACED VIDEO All computer monitors use a progressive scan - each scan line in sequence. Interlacing is only for CRT monitors. LCD monitors work totally differently - no need to worry about. Interlacing is for broadcast TV. Every other line displayed alternatively. FRAME RATES As we transition from analogue video to digitla video. Film is 24 fps, PAL video 25 fps. NTSC 30fps. Actually film and NTSC are slightly different but we don't need to worry about that for now. IMAGE SIZE All video is shot at 72 px/inch - DV NTSC - 720 x 480 (SD is 720 x 486) DV PAL - 720 x 576 (SD PAL is 720 x 576) HD comes in both progressive and interlaced. HD480i is usual broadcast TV 480p is 480 progressive. 720i is 720 interlaced 720p is progressive. 720 means 720 vertical lines 1080 is 1080 vertical lines. 1080i is most popular. 720p is 1280 x 720, HD 1080 is 1920x1080px. All HD formats are 16:9 aspect ratio. Traditional TV is 4:3 aspect ratio. HDV is 1440 x 1080. New format - is it the new HD version of DV? Cameras like the Sony and JVC make minor alterations to this format when shooting In summary HD 1080i = 1920 x 1080 HD 720p = 1280 x 720 Traditional = 720 x 480 (NTSC) 720 x 576 (PAL) VIDEO OUTPUTS Analog Composite, S-Video, Component in increasing quality. -
