Proper calibration of digital displays again resulted in huge improvements in picture quality and extended their lifespan especially for the phosphor based plasmas. The displays were prohibitively expensive but for the few early adopters the benefits were huge. Plasma televisions provided the first digital video display technology available for the home viewer with LCD and DLP technologies following shortly thereafter. We simply were not seeing all the potential benefits of the digital software. The next logical step was to develop new display technologies as the DVD format exceeded the capabilities of most tube based TVs. The goal was to achieve as film-like an image as possible given the superior encoding capabilities of the DVD format.
The Video Essentials DVD and Avia DVD calibration discs made their appearance providing an even more precise tool to optimize our video displays. Our TVs were still NTSC and analog but the improvements in picture and sound quality from the DVD were phenomenal, making the DVD the most rapidly adopted new format in the history of the electronics industry. Remember the dull, washed out images one experienced on our TVs after a few years?įast forward to the late ’90s and the incredible jump in home video performance brought to us courtesy of the DVD format.

Leaving the TV in this mode meant the phosphors were literally being burnt off at a rapid pace, shortening the optimal performance capability of the TVs by a significant margin. The TVs’ images needed to jump out at the consumer on the brightly lit retail sales floor so manufacturers had the contrast or white levels set very high. Proper calibration of these designs not only improved performance but also prolonged the life of the TV as all TV sets had incorrect settings out of the box. Our old TVs were big and clunky because they were based on a vacuum tube with phosphors painted on the inside of the screen that were excited by an electron gun. Back in the day of analog NTSC televisions, standard definition broadcasts and VHS tape, the benefits derived from proper calibration were still clear for all to see. The mandate for ISF is to optimize the performance of video displays in the home environment with a significant boost in picture quality as well as prolonging the life of our video displays. This original NTSC test disc was brought to us by video guru Joe Kane who, in conjunction with Joel Silver, helped establish a set of video standards that evolved into what is now known as the ISF or Imaging Science Foundation. In order to optimize your TV or projector you will need to use appropriate calibration material.įor the better part of the last two decades, various video calibration discs have been available for this purpose, starting with the original Video Essentials disc on the now defunct laser disc format.

The HD standard brings with it a new set of performance parameters that need to be optimized in order to unlock the full potential of HD video. The most dramatic and accessible improvements have been in the video domain with the advent of affordable high definition displays and a wide variety of high definition material courtesy of HD broadcasts and the Blu-ray format. The digital age has provided us with many innovations both in the audio and video world over the past several years. Secrets of Home Theater and High Fidelity is not the creator or sponsor of the Spears & Munsil High Definition Benchmark, Blu-ray Edition.Admin T23:44:15+00:00 January 13th, 2011 | Features, Video | 14 Comments *Secrets of Home Theater and High Fidelity is at. They have done video encoding and compression for multiple HD DVD and Blu-ray discs, and have consulted for and produced test patterns and evaluation material for a variety of video and consumer electronics companies. They created standard-definition test and calibration discs for Anchor Bay Technologies. They were the first to publicly document and explain the well-known chroma upsampling error in MPEG-2, H.264 and VC-1 decoders.
They set a new standard for evaluation of DVD players with the DVD Player Benchmark™ and Progressive Scan Shootout at Secrets of Home Theater and High Fidelity®*. They are inventors or co-inventors of multiple patents in video and image processing. Stacey Spears and Don Munsil have written many seminal articles, together and separately, on inside secrets of video decoding, processing, and deinterlacing.
