RAID
Redundant Array of Independent Disks - a method used to standardize and categorize fault-tolerant disk systems. RAID levels provide various mixes of performance, reliability, and cost. Three of the the most implemented RAID levels are Level 0 (striping), Level 1 (mirroring), and Level 5 (RAID-5). RAID disk systems may offer advantages during video capture.



RAMbo drive
A DVD-RAM drive capable of reading and writing CD-R and CD-RW media.

Reed-Solomon
An error-correction encoding system that cycles data multiple times through a mathematical transformation in order to increase the effectiveness of the error correction, especially for burst errors (errors concentrated closely together, as from a scratch or physical defect). DVD uses rows and columns of Reed-Solomon encoding in a two-dimensional lattice, called Reed-Solomon product code (RS-PC).



Region Coding
Region coding is how Hollywood studios stagger DVD movie releases across the planet. These codes ensure that one country doesn't get a DVD movie before the same movie is out in that country's theatres. In their corporate omniscience, movie studios have carved the planet into regions with each region having a specific code.

All DVD players and discs have region codes. A DVD player and disc must be of the same region or the disc will not play.

If you want to watch movies from other countries, you need a multiregion DVD player. This will allow you to play any disc from any region. However, because TV standards differ, you might need a specialized NTSC / SECAM / PAL TV or a DVD player that can output any signal to the standard your TV accepts. TechTV



Region Coding Enhancement
Abbreviated RCE, it is a digital enhancement added to some studios DVDs to stop region 1 (R1) DVDs from playing on Region-free DVD players.

Registry
A database repository for information about a computer's configuration. The registry contains information that Windows continually references during operation, such as:

- Profiles for each user.
- The programs installed on the computer and the types of documents each can create.
- Property settings for folders and program icons.
- What hardware exists on the system.
- Which ports are being used.

The registry is organized hierarchically as a tree and is made up of keys and their subkeys, hives, and entries.

If programs do not uninstall properly or store configuration information not available via the program interface you might have to manually edit the registry. You can access the registry by running the program RegEdit. WARNING - if you incorrectly modify the registry you can disable programs, file associations or the whole operating system. Making a backup copy of the registry is highly recommended.



Resampling
The process of converting between different spatial resolutions or different temporal resolutions. This may be based on simple sampling of the source information at higher or lower resolution or may include interpolation to correct for differences in pixel aspect ratios or to adjust for differences in display rates.



Resolution
1) A measurement of relative detail of a digital display, typically given in pixels of width and height;

2) the ability of an imaging system to make clearly distinguishable or resolvable the details of an image. This includes spatial resolution (the clarity of a single image), temporal resolution (the clarity of a moving image or moving object), and perceived resolution (the apparent resolution of a display from the observer's point of view). Analog video is often measured as a number of lines of horizontal resolution over the number of scan lines. Digital video is typically measured as a number of horizontal pixels by vertical pixels. Film is typically measured as a number of line pairs per millimeter;

3) the relative detail of any signal, such as an audio or video signal. Also see lines of horizontal resolution.



RGB
Video information in the form of red, green, and blue tristimulus values. The combination of three values representing the intensity of each of the three colors can represent the entire range of visible light.



Rip
To take off the audio or video from a CD or DVD. Often CD Audio is "ripped" to MP3 files or DVD video ripped to VOB files. VCDhelp ripping



RLC
Run-length coding. Lossless compression method that exploits contiguous samples with same value.



RS-PC
Reed-Solomon Product Code. An error-correction encoding system used by DVD employing rows and columns of Reed-Solomon encoding to increase error-correction effectiveness.
