On CRTs, it is used to even out the fading of the picture in each frame. The phosphor will glow for a specific amount of time. Scanning every odd row of the image on the first pass then scanning all the even rows on the second pass, allowed the fading to be unpronounced.

What does p in a palsma tv stands for?

Assuming you are asking what does the "p" stand for in Plasma and other digital televisions in the resolution such as 1080p vs. 1080i. The 'p' stands for "progessive scan" and the 'i' stands for "Interlaced". In a progressive scan each line is displayed sequentially from top to bottom. An interlaced scan displays every othe line in one pass then the other lines in a second pass.


Does a 1080i dvd-vcr combo work on a 1080p TV?

I do believe that it will work if your buy a converter. That is if they make a converter from interlaced to progressive scan.


Why is odd lines used in tv systems?

To Ensure Interlaced Scanning


Which provides better quality an interlaced monitor or noninterlaced monitor?

A non interlaced monitor is one where all the scan lines occur sequentially, whereas an interlaced monitor is one where all the odd scan lines occur, followed by all of the even scan lines, in alternating painting of the phospher.


What do interlace and non-interlace signals mean?

To understand this concept you have to understand the different types of tv. First you have CRT (cathode ray tube) This type of tv is usually interlaced and is the style that most people have. It has been around since the beginning of TV. The next style is the LCD/Projection/Plasma. These TVs are all progressive or non-interlaced. Cathode Ray Tubes display a picture by shooting a cathode ray at electrons giving you a picture. The cathode ray scan down the screen in lines. If it scans interlaced it will scan lines 1,3,5,7 etc. and then it will go back and scan lines 2,4,6,8 etc. Because of our mental ability to "fill in the gaps" we percieve it as an uninterupted picture. Non-interlace pictures scan all lines from top to bottom. Progressive scan gives you a higher quality image but it is harder to maintain brightness a constant picture because it takes longer to get through all of the lines than just half of them. This scanning rate is also called the refresh rate. Plasma screens and LCD essentially refresh all of their pixels at the same time so they are neither progressive nor interlaced.


What is 760P?

760P is not a standard used by HDTV. The closest standard is 720P. The 760 may refer to the horizontal scan lines of the TV/signal. The P stands for Progressive Scan which is how the frames or the picture are put together. Progressive Scan draws all the lines of each frame sequentially as opposed to another method, Interlaced, which draws only the odd or even lines of a frame and then vice versa for the next frame.


What is the difference between progressive and interface modes in television programming?

Interlaced, not interface. Interlaced scans every second line. Progressive does not.


What is progressive scan on a DVD Does it make any difference weather your DVD player has it or not?

Progressive scan provides a more film-like image display that is more pleasing for viewing DVDs on a television display. Video signals are generated using horizontal lines. An regular, or interlaced, picture draws every other line and alternates between drawing odd lines and even lines. A progressive scan picture draws every line in sequence. Therefore, a progressive scan video signal sends twice as much data than an interlaced signal each time it draws an image on the screen. This basically means that if you have a TV that can display more than just the standard resolution you will get twice the picture clarity.


What are Disadvantages of non interlaced monitor?

A method of refreshing the image on a monitor. Instead of refreshing the entire image (non-interlaced), an interlaced monitor refreshes the odd-numbered scan lines first, then refreshes the even-numbered scan lines on the second pass. This reduces the amount of new information that has to be passed on each sweep, but causes almost unnoticeable flicker, that can result in eye fatigue.


Where is the volcano in Canada?

There are 2 things to note when talking about HDTV. The first is resolution, which is how "clear" the picture is. This is indicated by the 720 or 1080 part of the number. This is how many pixels tall the screen is. (1080 is a clearer picture, because it is 360 pixels taller). The second part, the "i" and "p" are the type of scan the TV has. "i" stands for interlaced and "p" stands for progressive. Progressive is generally considered to be superior to interlaced. So, the best available TV right now would be a "1080p".


Why is an odd number of line used for scanning?

An odd number of lines are used in interlaced scanning because, in each field of the TV, the scanning displaces the field by a half of the area. If there were an even number of lines, it would flicker noticably.


What does 1080 i refer to?

1080 vertical lines of resolution, but the i stands for interlaced, as opposed to p which stands for progressive. The difference is that interlaced updates odd lines, then even lines alternately. Progressive updates the entire image with each scan. If your TV set can display 1080i then it can also display 1080p (which transmits all the vertical lines at once) although the only media capable of a 1080p signal is a Blu-Ray disk.
