Dual Laser Pickup - DVD technology that incorporates two independent laser systems. Enables reading multiple disc formats including DVD, CD, VCD, CD-R and CD-RW.
Resolution - A measure of how closely packed the dots in a bitmapped image are, often expressed in dots per inch (dpi) or lines per inch (lpi). The higher the number, the higher the quality. However, doubling the resolution of an image results in a computer file four times as large, requiring more hard disk space and computer memory to handle the higher quality image. Resolution is also used to describe how close together a computer printer can print dots in an image. Again, the larger the number, the higher the quality. It is important to know the capability of the printer's resolution before scanning an image in order to get enough information to print the best quality.
Surround Sound - An audio reproduction system using four or more speakers to simulate the three-dimensional effect of a live music performance or a cinematic environment. With surround sound, the phase of the original sound is delayed from a two-channel source, creating a surround effect and allowing you to simulate stereo sound even from a monaural source.
Scan Velocity Modulation - Varies the scanning speed of the electron beam to accommodate light/dark transitions. This increases contrast at image edges for a clear, well-defined picture.
