Bandwidth. Indicates the range of frequencies (in Hertz) you need a signal for transmission.This term describes data-carrying capacity--in other words, how much (and how fast) data flows on a given transmission path. It can apply to network connections, system buses, or any "pipe" through which data pours.
A projector's bandwidth must be high
The process of transferring a film or other material to a VCR, DVD or a broadcast in a way that matches the aspect ratio of 4:3 for NTSC, as well as for most televisions today. This results in a significant amount of loss of image information, primarily in the width of it.
At the beginning of a film cassette, you usually will see a message that argues that
The "burn" can damage the screens have phosphor-coated plasma televisions and CRTs are the most vulnerable. "Burn" or image retention effect can occur when a static image like a video game or logo of the station remains on the screen for a long period. Over time, this image can be recorded in the phosphor coating, leaving ghostly
Describes the presence of dark portions in a video image. The black is the absence of light, then to create the black portions of an image display should be capable of extinguishing as much light as possible. The screens with high capacity level of blacks not only produce deeper blacks, but also reveal further details of shadow in dark scenes. The CRT (tube
It is measured in bits per second "and is used to express the speed at which they transmit or process the data. A higher bit rate, the more data processed and therefore higher image resolution. The formats of digital video is usually measured in megabits per second (Mbps). (One megabit equals one million bits). The maximum bit rate for DVD is 10 Mbps;
Watch TV with projection.
A big screen TV set is usually the center of a home entertainment system. The popular direct view 32 and 36 inch screens use a large glass picture tube. Giant screens, the 50, 56, 60 inch and larger, use a set of three small picture tubes with lens and mirrors projecting to the rear of a large plastic screen. Things have changed.
Refers to a projector with a briefcase that fits in any baggage compartment or even under the seat of a passenger on an airplane. A briefcase for projector that does not comply with these conditions need to be documented as luggage or sent into the area of responsibility of the airline. Make sure you have a briefcase or resistant hard when you register your
Subjective visual sensation by which an area appears to emit more or less light. It is measured in lumens. Brightness Ratio is the difference between the brightest and darkest object in a picture. Too much of a difference can cause unacceptable contrast. A brightness control makes an image brighter; however, when it is combined with a contrast, or white
One of the signs to distinguish the color that is used in PAL. It is obtained by subtracting the luminance signal (Y) of the signal blue (B). Luminance (Y) is Brightness Signal which carries information about the amount of light at each point in the image. A liquid crystal based display device may include an illumination source, a plurality of liquid
Unlike other technologies such as LCD which use just 3 primary colors to produce the image, DLP® Technology with BrilliantColor™ uses up to six separate colors.
Projectors deliver more than a big picture. Projectors offer brilliant color, vivid contrast and detailed images. They're light, mobile and highly connectable to other home theater
