2. Interlaced video - Wikipedia

   en.wikipedia.org/wiki/Interlaced_video

   Animation of an interlaced CRT TV display, showing odd and even fields being scanned in sequence, to display a full frame. Interlaced video (also known as interlaced scan) is a technique for doubling the perceived frame rate of a video display without consuming extra bandwidth.

3. Field (video) - Wikipedia

   en.wikipedia.org/wiki/Field_(video)

   Normally, two fields comprise one video frame, in what is known as 2:1 interlacing. 3:1, 4:1 and 5:1 interlacing also exist. [ 1 ] [ 2 ] When the fields are displayed on a video monitor they are " interlaced " so that the content of one field will be used on all of the odd-numbered lines on the screen, and the other field will be displayed on ...

4. Kell factor - Wikipedia

   en.wikipedia.org/wiki/Kell_factor

   Interlacing itself does not affect Kell factor, but because interlaced video must be low-pass filtered (i.e., blurred) in the vertical dimension to avoid spatio-temporal aliasing (i.e., flickering effects), the Kell factor of interlaced video is said to be about 70% that of progressive video with the same scan line resolution.

5. Progressive segmented frame - Wikipedia

   en.wikipedia.org/wiki/Progressive_segmented_frame

   Progressive segmented Frame (PsF, sF, SF) is a scheme designed to acquire, store, modify, and distribute progressive scan video using interlaced equipment.. With PsF, a progressive frame is divided into two segments, with the odd lines in one segment and the even lines in the other segment.

6. Vertical interval timecode - Wikipedia

   en.wikipedia.org/wiki/Vertical_interval_timecode

   Field flag (bit 35 for 29.97/30 frame/s, bit 75 for 25 frame/s): This is an additional least-significant bit for the frame number, distinguishing the two interlaced fields in one video frame. It is set to 0 during the first field of a frame, and to 1 during the second.

7. Line doubler - Wikipedia

   en.wikipedia.org/wiki/Line_doubler

   A line doubler is a device or algorithm used to deinterlace video signals prior to display on a progressive scan display.. The main function of a deinterlacer is to take an interlaced video frame which consists of 60 two-field interlaced fields of an NTSC analogue video signal or 50 fields of a PAL signal, and create a progressive scan output.

   Years-long contract fights at media companies came to a head in 2024, leading to walk-outs by unions from the New York Times, NBC and Forbes.

9. Video - Wikipedia

   en.wikipedia.org/wiki/Video

   Video is an electronic medium for the recording, copying, playback, broadcasting, and display of moving visual media. [1] Video was first developed for mechanical television systems, which were quickly replaced by cathode-ray tube (CRT) systems, which, in turn, were replaced by flat-panel displays of several types.
