  2. List of broadcast video formats - Wikipedia

    en.wikipedia.org/wiki/List_of_broadcast_video...

    This is the standard broadcast frame rate for countries with an NTSC history—mainly the US, Canada, Japan and South Korea. This was the standard format of American TVs due to the displaying of CRT screens which were common place before the wide spread use of digital monitors. Alternating currents are used to time each scan, by which two scans ...

    en.wikipedia.org/wiki/Cardiac_resynchronization...

    Cardiac resynchronisation therapy (CRT or CRT-P) is the insertion of electrodes in the left and right ventricles of the heart, as well as on occasion the right atrium, to treat heart failure by coordinating the function of the left and right ventricles via a pacemaker, a small device inserted into the anterior chest wall.

    CRT LCD Plasma OLED; Static contrast ratio Finite or infinite [citation needed] 150 to 8,100:1 [citation needed] Typically 1,000:1 - 3,000:1, Some models measured up to 20,333:1 [citation needed] "Between 0.0001 and 0.00001 nits" "Sony claims an OLED contrast range of 1,000,000:1."

  5. High-dynamic-range television - Wikipedia

    en.wikipedia.org/wiki/High-dynamic-range_television

    Standard dynamic range (SDR) is still based on and limited by the characteristics of older cathode-ray tubes (CRTs), despite the huge advances in screen and display technologies since CRT's obsolescence. [1] SDR formats are able to represent a maximum luminance level of around 100 nits. For HDR, this number increases to around 1,000–10,000 nits.

    Coordinated Video Timings (CVT; VESA-2013-3 v1.2 [1]) is a standard by VESA which defines the timings of the component video signal.Initially intended for use by computer monitors and video cards, the standard made its way into consumer televisions.

  9. Standard-dynamic-range video - Wikipedia

    en.wikipedia.org/wiki/Standard-dynamic-range_video

    The first CRT television sets were manufactured in 1934 and the first color CRT television sets were manufactured in 1954. [4] [5] The term "standard-dynamic-range video" was adopted to distinguish SDR video from high-dynamic-range video (HDR video), a new technology that was developed in the 2010s to overcome SDR's limits.
