    The resolution of 960H depends on whether the equipment is PAL or NTSC based: 960H represents 960 x 576 (PAL) or 960 x 480 (NTSC) pixels. [29] 960H represents an increase in pixels of some 30% over standard D1 resolution, which is 720 x 576 pixels (PAL), or 720 x 480 pixels (NTSC). The increased resolution over D1 comes as a result of a longer ...

  7. Chroma subsampling - Wikipedia

    en.wikipedia.org/wiki/Chroma_subsampling

    Chroma subsampling. Widely used chroma subsampling formats. Chroma subsampling is the practice of encoding images by implementing less resolution for chroma information than for luma information, taking advantage of the human visual system's lower acuity for color differences than for luminance. [1]

    The update includes native encoding of 4:2:2 and 4:2:0 formats in six-pixel containers, 14/16 bits per color, and minor modifications to the encoding algorithm. On 4 January 2017, HDMI 2.1 was announced which supports up to 10K resolution and uses DSC 1.2 for video that is higher than 8K resolution with 4:2:0 chroma subsampling. [9] [10] [11]
