  2. Colorburst - Wikipedia

    en.wikipedia.org/wiki/Colorburst

    Colorburst is an analog and composite video signal generated by a video-signal generator used to keep the chrominance subcarrier synchronized in a color television signal. By synchronizing an oscillator with the colorburst at the back porch (beginning) of each scan line , a television receiver is able to restore the suppressed carrier of the ...

  3. Tint control - Wikipedia

    en.wikipedia.org/wiki/Tint_control

    To correct for phase errors, a tint control is provided on NTSC television sets, which allows the user to manually adjust the phase relationship between the color information in the video and the reference for decoding the color information, known as the "color burst", so that correct colors may be displayed.

  4. Colour banding - Wikipedia

    en.wikipedia.org/wiki/Colour_banding

    Colour banding is a subtle form of posterization in digital images, caused by the colour of each pixel being rounded to the nearest of the digital colour levels. While posterization is often done for artistic effect, colour banding is an undesired artifact.

  5. High-dynamic-range television - Wikipedia

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

    High-dynamic-range television (HDR-TV) is a technology that uses high dynamic range (HDR) to improve the quality of display signals. It is contrasted with the retroactively-named standard dynamic range (SDR). HDR changes the way the luminance and colors of videos and images are represented in the signal and allows brighter and more detailed ...

  6. High-dynamic-range rendering - Wikipedia

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

    Rec. 709 defines the color space for HDTV, and Rec. 2020 defines a larger but still incomplete color space for ultra-high-definition television. Since the 2010s, OLED and other HDR display technologies have reduced or eliminated the need for tone mapping HDRR to standard dynamic range.

  8. Test card - Wikipedia

    en.wikipedia.org/wiki/Test_card

    Test cards typically contain a set of patterns to enable television cameras and receivers to be adjusted to show the picture correctly (see SMPTE color bars).Most modern test cards include a set of calibrated color bars which will produce a characteristic pattern of "dot landings" on a vectorscope, allowing chroma and tint to be precisely adjusted between generations of videotape or network feeds.

  9. Composite monitor - Wikipedia

    en.wikipedia.org/wiki/Composite_monitor

    A critical factor in the quality of this display is the type of encoding used in the TV camera to combine the signal together and the decoding used in the monitor to separate the signals back to RGB for display. Composite monitors can be very high quality, with professional broadcast reference displays costing US$10k-$15k as of 2000.
