Unlike traditional, interlaced video where interlacing is done on a line by line basis, showing either odd or even lines of video at any one time, thus requiring 2 fields of video to complete a video frame, MUSE used a four-field dot-interlacing [34] [14] [35] [36] [37] cycle, meaning it took four fields to complete a single MUSE frame, [38 ...
The two sets of 25 fields work together to create a full frame every 1/25 of a second (or 25 frames per second), but with interlacing create a new half frame every 1/50 of a second (or 50 fields per second). [3] To display interlaced video on progressive scan displays, playback applies deinterlacing to the video signal (which adds input lag).
The "i" in 1080i stands for interlaced. This refers to how each video frame is displayed. Instead of showing the entire frame at once, the interlacing technique divides each frame into two separate fields. The first field contains all the odd-numbered lines (1, 3, 5, etc.), and the second field contains all the even-numbered lines (2, 4, 6, etc.).
Interlacing divides the frame into two fields, each containing half the number of lines. Each field is scanned in 1/60 second under the 525-line system (or 480i – often incorrectly referred to as NTSC) or 1/50 of a second under the 625-line system (or 576i – often incorrectly referred to as PAL). With interlaced systems there are an odd ...

The Linus Write-Top is an early tablet computer first released by Linus Technologies, Inc., of Reston, Virginia, in July 1988.It was the first tablet computer released to the public with support for pen input and handwriting recognition software.
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.
The combination of interlacing with block-based compression technique inherits all the drawbacks of the interlacing, while also reducing the efficiency of block-based compression. Because interlacing samples every other line without prefiltering, it increases the amount of high-frequency components in the signal fed to the block transformation.
