Component video signal
This signal is sent with its luminance signal and color signal independent. It creates higher image quality compared with an ordinary composite video signal because it bypasses the mixing and separating circuits. This signal is sent in three lines: the luminance signal (Y) and two color difference signals (PB/CB, PR/CR).
S video signal
S stands for Separate. This signal is sent with its luminance signal (Y) and color signal (C) separately. A
Composite video signal
This is the most common type of video signal. The luminance signal and color signal are sent combined in one line. Mixing and separating processes are necessary on both the send and receive sides. A pin cable is used for connection.
RGB signal
An RGB signal transmits color information by using a numeric representation of the primary colors of red, green and blue separately. When the signal is received, it can be expressed in various colors by adding and mixing colors. This signal is widely used for sending and receiving color images between computers. Horizontal and vertical sync signals are also necessary.
Dconnector
*This connector is designed for the Japanese D format only. This connector is used for sending and receiving the image signal between the latest type of A/V components. This connector can receive the component signal by using a D connector cable. There are five levels
DVI connector
A digital RGB signal is sent from a computer to this connector differencially. A
Standby
The state under which the circuit to receive
Test pattern
Test patterns are stored in this unit to adjust the position and focus of the projected image on the screen.
Aspect ratio (aspect)
This basically means the
Interlace
The common type of scanning for most televisions. It divides into two fields: even and odd numbered lines of the field to build one frame of an image.
Progressive
This displays all the scanning lines of the entire frame at one time. It greatly reduces the flicker that is more noticeable on a larger screen to create a sharp and smooth image. This unit projects by progressive scanning.
Key stone
If this unit has an elevation or depression angle when projecting on the screen, the image is distorted in a trapezoid. This item electrically corrects the distortion. Two types of correction are available; “Normal correction” and “Full correction”.
Letter box
This is the method to convert the content of a film in landscape orientation to 4:3 signal. It is possible to watch the landscape image without trimming by adding a black bar on the top and bottom of the screen. Vertical resolution may be sacrificed to some extent.
Squeeze
This method horizontally squeezes the film so that the aspect ratio is 4:3 when recording the film on a video medium. The squeezed image must be passed through the desqueezing circuit otherwise the image remains in a slender shape.
Vista size
One of the film sizes. The aspect ratio is 1.85:1 in North America and 1.66:1 in Europe.
Cinema scope size
This is the widest film size that uses a 70 mm film. The aspect ratio is 2.35:1.
