Display ing less than the complete area of a TV image to a viewer (i. e. , scanning inside the Active Image area). All TV sets are overscanned by a few percent. Some professional devices, such as standards converters, perform the overscan and crop. Synonyms: Overscanning
Is a measurement of what part of the picture that is being sent to the TV that is not being displayed. Excessive overscan can cause you to miss seeing 5 to 10 percent of the picture. A good indication of this being a problem is when you see sporting event clocks and scores that are only partially displayed.
The "spreading out" of a television image by the raster scan method of display so that the edges of the picture are off the edge of the television tube. This guarantees no unsightly borders in the television picture.
Extending beyond the normal viewing area on the monitor screen.
The portion of the movie blocked by the edges of your TV screen.
The adjustment of a TV set so that all four edges of the video frame are slightly outside the screen. This was done by TV manufacturers decades ago when TV pictures shrank if the power line voltage dropped, the latter occurring often when everyone was using a lot of electricity. With overscan, there would still be enough picture to completely cover the screen when the picture shrank, and viewers stopped complaining that TV sets were defective.. However program material at the edges of the screen is lost. Today's TV sets don't suffer from picture shrinkage as much but overscan still occurs and too much of it is now regarded as a quality control deficiency. Still, TV producers keep important material away from the edges of the video frame, and many video cameras have marked in their viewfinders a "safe area". Sometimes the electronics in the TV set are deficient (rounded off horizontal and/or vertical sweep sawtooth waveforms) that the extreme edges of the picture are "squished" and overscan is deliberately used to hide this distorted material outside the screen borders.
The border area (around 10%) of video that is cropped by televisions (more..)
The result of the TV scan lines exceeding the boundaries of the display screen.
A video monitor condition in which the raster extends slightly beyond the physical edges of the CRT screen, cutting off the outer edges of the picture.
The border surrounding the writable area on the screen. On a PC it is very small but you can change its colour, e.g. in CPCEMU with "BORDER 10". On the CPC the overscan is much wider, so programmers have looked for possibilities to write to it. With a programming trick it is possible to write to the whole screen. This programming technique is called overscan.
the slightly zoomed-in view of images on televisions designed to cut off untidy-looking edges. Overscan is the reason film and TV programme makers have to avoid using the absolute edge of the frame for important parts of the picture.
Video images generally exceed the size of the physical screen. The edge of the picture may or may not be displayed, to allow variations in television sets. The extra area is called the overscan area. Video productions are planned so critical action only occurs in the center safe title area. Professional monitors are capable of displaying the entire video image including the overscan area.
To scan a little beyond the display raster area of the monitor so that the edges of the raster are not visible. Television is overscanned; computer displays are underscanned.
A video-display effect in which the image is enlarged so that its edges are off the screen.
The area at the edges of a television tube that is covered to hide possible video distortion. Overscan typically covers about 4 or 5 percent of the picture.
Overscan is extra image area around the four edges of a video image that is not normally seen by the viewer. It exists because television sets in the 1930s through 1970s were highly variable in how the video image was framed within the cathode ray tube (CRT).
