Glossary

sRGB

An international standard for colour intervals that was formulated so that colours which

 

are reproduced by video equipment can be handled easily by computer operating systems

 

(OS) and the Internet.

 

 

SVGA

A type of video signal with a resolution of 800 (horizontal) x 600 (vertical) dots which is

 

used by IBM PC/AT-compatible computers.

 

 

S-Video

A video signal which has the luminance component and colour component separated in

 

order to provide better image quality.

 

It refers to images which consist of two independent signals: Y (luminance signal), and C

 

(colour signal).

 

 

Sync.

The signals output from computers have a specific frequency. If the projector frequency

(Synchronisation)

does not match this frequency, the resulting images will not be of a good quality. The

 

process of matching the phases of these signals (the relative position of the crests and

 

troughs in the signal) is called "synchronisation". If the signals are not synchronized,

 

problems such as flickering, blurriness and horizontal interference can occur.

 

 

Tracking

The signals output from computers have a specific frequency. If the projector frequency

 

does not match this frequency, the resulting images will not be of a good quality. The

 

process of matching the frequency of these signals (the number of crests in the signal) is

 

called "tracking". If tracking is not carried out correctly, wide vertical stripes will appear

 

in the projected images.

 

 

VGA

A type of video signal with a resolution of 640 (horizontal) x 480 (vertical) dots which is

 

used by IBM PC/AT-compatible computers.

 

 

XGA

A type of video signal with a resolution of 1024 (horizontal) x 768 (vertical) dots which

 

is used by IBM PC/AT-compatible computers.

 

 

YCbCr

The carrier signal which is contained in the colour bar signal used in modern TV

 

transmissions. The name comes from the Y (luminance) signal and the CbCr (chroma

 

(colour)) signals.

 

 

YPbPr

The carrier signal which is contained in the colour bar signal used in high-definition TV

 

(HDTV) transmissions. The name comes from the Y (luminance) signal and the PbPr

 

(colour difference) signals.

EMP-30 specifications

The Epson EMP-30 is a portable projector that has garnered attention for its performance and versatility. Designed for both business presentations and home entertainment, the EMP-30 balances features that cater to a variety of users.

One of the standout characteristics of the Epson EMP-30 is its brightness. It offers a brightness level of 2,500 ANSI lumens, making it suitable for use in both well-lit and dim environments. This feature ensures that images remain clear and vibrant, even under challenging lighting conditions. The resolution of the projector stands at XGA (1024 x 768), which is ideal for standard presentations and displays. This high resolution ensures text and images are sharp, making it easier to engage an audience.

The EMP-30 uses 3LCD technology, which is known for producing vivid colors and consistent image quality. Unlike traditional projectors that rely on a single light source, 3LCD utilizes three separate liquid crystal panels to project red, green, and blue light simultaneously. This results in enhanced color accuracy and a broader color gamut, which is particularly noticeable in presentations featuring detailed graphics or videos.

Portability is another key feature of the Epson EMP-30. Weighing around 2.8 kg, it is lightweight enough to be transported easily between home, office, or educational environments. The compact design makes it user-friendly, allowing for quick setups in various locations.

Connectivity options are plentiful, including VGA, composite, and S-video inputs, enabling compatibility with a wide array of devices such as laptops, DVD players, and gaming consoles. The EMP-30 also features an audio output to connect external speakers for improved sound quality during presentations or movie screenings.

Another notable characteristic is its lamp longevity. The ECO mode extends the lamp life up to 5,000 hours, reducing maintenance costs and the frequency of replacements.

Additionally, the EMP-30 offers convenient features such as automatic vertical keystone correction, ensuring that images are displayed correctly even if the projector is angled. The user-friendly interface simplifies operation, making it accessible for users of all experience levels.

In conclusion, the Epson EMP-30 stands out as a versatile and reliable projector suitable for various applications. With its brightness, advanced 3LCD technology, portability, and user-friendly features, it is an excellent choice for anyone in need of a dependable projection solution.
