CODEC (Coder/Decoder)
A mathematical system for compressing (encoding) and decompressing (playing back) a video or audio file. CODECs can be hardware or software-based, or both. Hardware CODECS are often more efficient, but the trade-off is that not all users will have the special hardware needed to play back the file.
Colour Book Standards
The standards that Phillips sets out that technically define the optical disc formats. Each format has its own colour.
Color Correction
In imaging, this refers to the process of matching the colors in a digital reproduction of an image to an analog original, such as a photograph. Adobe Photoshop is the standard application for color-correcting images. In film, this refers to adjusting the final print so that colors match from shot to shot, regardless of the film stock and camera used.
Compression
The process of reducing the size of a media file by eliminating data. Higher compression means that the compression utility (usually a software program or a combination of hardware and software) defines greater amounts of data (such as larger areas of an image) as redundant, but at certain points the human eye will register the missing information as quality loss. The trade-off is that highly compressed images can be delivered more efficiently over a network.

Jewel Cases
The original CD case that has been used since the compact disc was first released. It is a three-piece plastic case which usually contains a compact disc along with the liner notes and a back card. Two opposing transparent halves are hinged together to form the casing, the back half holding a media tray that grips the disc by its hole. The back media tray snaps into the back cover, and is responsible for securing the disk. In its center is a circular hub of teeth which grip the disc by its hole. This effectively suspends the disk in the middle of the container, preventing the recording surface from being scratched. Jewel cases are occasionally used for DVDs as well as CDs, but generally not for those that contain major film releases.
JPEG (Joint Photographic Experts Group)
Refers to the widely-used image file format for use on the web and is the recommended file type for photo images. It has relatively high quality and low file size and adjustable compression with little perceptible loss in image quality.
Letterbox(LTBX)
The practice of transferring film shot in a widescreen aspect ratio to standard-width video formats while preserving the film's original aspect ratio. The resulting videographic image has mattes (black bars) above and below it; these mattes are part of the image (i.e., of each frame of the video signal).

O
Offset Printing
Commercial offset printing is the process of printing used in large scale printing factories. Ink is transferred to the paper from a metal plate to an intermediary surface - called a blanket - then onto the paper as it passes through the machine. Offset printing is used for most high volume paper printing projects as it is cost effective and allows very high levels of control of ink levels.
Orange Book
A recordable CD standard for CD-R and photo CD.
P
Pantone
Solid colours that are mixed from a standardized formula. Pantone colours printed on the same stock will always be the same, whereas CMYK printing can have variances and is dependent on the machine operator to match a proof.
PDF (Portable Document Format)
A document format from Adobe that preserves formatting such as specific fonts and graphics by embedding them into the file - created with Adobe Acrobat.
Pixel
A pixel (or picture element) is a single point in a raster image. The pixel is the smallest addressable screen element; it is the smallest unit of picture that can be controlled. Pixels are normally arranged in a 2-dimensional grid, and are often represented using dots or squares. The intensity of each pixel is variable.
PNG (Portable Network Graphics)

Red Book
Part of the Phillip colour book standards and describes the CD Audio format.
Regional Coding
Used in DVD players to only allow DVDs encoded for use in one of the six world regions to be played, as established by the major film companies.
Resolution
Resolution and DPI are often used interchangeably, but they are quite different. Any digital image is composed of pixels. The pixels are the small coloured square dots that can sometimes be seen when images are enlarged too much, or if you look at your screen close enough. Resolution is the number of pixels in the horizontal direction by the number of pixels in the vertical direction. For example, a picture with 1200 pixels at the horizontal direction and 2100 pixels at the vertical direction would have a resolution of 1200 x 2100 pixels (pronounced 1200 by 2100 pixels). The bigger the resolution, the bigger the image is. It will take more disk space, occupy more memory when loaded, and will take longer to be transferred through the Web. On the other hand, the bigger the resolution, the better the image looks when printed.
RGB (Red Green Blue)
Most widely used color model which is an additive color model in which red, green, and blue light are added together in various ways to reproduce a broad array of colors. The main purpose of the RGB color model is for the sensing, representation, and display of images in electronic systems – TV and computers, and has also been used in conventional photography.
.rtf

S
SECAM
The video format used in France and some other countries. SECAM has 625 lines total, 576 lines visible per frame, and has a frame-rate of 25 frames per second.
Silk Screen Printing
Silk screening is the process that you may remember from school when you "silk screened" images on your T-Shirts. A screen is made from your artwork through which ink is pushed arriving on the substrate - in our case it is your Disc label. Silk screening is provides excellent quality for solid colours, but is not recommended for images of intricate patterns or low ink densities due to the poor ability to control ink dot delivery at low levels.
Stamper
A stamper is the device made from a Glass Master and is used as the ‘mold’ from which discs are made.
Standards Conversion
The transfer of one video standards format to another. For example, European tapes are made in the PAL format and need to be converted to NTSC format to be viewed in North American countries.
Streaming Media
Video or audio transmitted over a network that users can begin to play immediately instead of waiting for the entire file to download. Typically a few seconds of data is sent ahead and buffered in case of network transmission delays. (Although some data is buffered to the hard drive, it is written to temporary storage and is gone once viewing is complete.) RealMedia, QuickTime and Windows Media are the most common streaming formats.
Surround Sound
A sound system which creates the illusion of multi-directional sound through speaker placement and signal processing. See also Dolby, SDDS, DTS, THX.
T-U
Table of Contents (TOC)
Information held on the disc outlining the start position of tracks in the area of the CD before audio or data.
Thermal Printing
A printing process that uses solid colour ribbons to transfer an image onto a disc. It uses a small amount of heat to effect the transfer.
TIFF (Tagged Image File Format)
An image file output format. TIFF files are lossless, meaning the compression they apply to an image doesn't create artifacts that can degrade the appearance of the image. TIFF files are often used for archiving high quality versions of an images, such as images intended to be reproduced in print or studied digitally in minute detail.
