multi-channel (surround sound) audio.
DVD-R (DVD Recordable) - A DVD for- mat that allows a one-time recording of data.
DVD-Video - The type of pre-recorded DVD format used for movies.
JPEG (Joint Photographic Experts Group) - Pronounced "jay-peg", it is an ISO/ITU standard for compressing still digital images. JPEG uses a lossy compression scheme, meaning data (image detail) is per- manently discarded during the compression process. Higher compression means more data is discarded but file size is smaller. With different levels of compression available, the loss of image detail and quality can range from imperceptible to very noticeable.
LCD (Liquid Crystal Display) - An ener- gy efficient, flat-panel display made up of a liquid crystal that is sandwiched between lay- ers of glass or plastic and becomes opaque when electric current passes through it. The
contrast between the opaque and transparent areas forms the image.
Lithium Ion - A rechargeable battery tech- nology that provides about a 10-15% improvement in charge per pound over nickel metal hydride.
MP3 - A popular format used for music files that can be downloaded from the Internet. MP3 employs a lossy compression scheme referred to as “perceptual audio coding” to compress CD-quality sound by a factor of 12. A CD that would normally hold a dozen or so uncompressed songs can easily hold 100 MP3s.
MPEG (Motion Pictures Experts Group) - Pronounced "em-peg", it is an ISO/ITU standard for compressing video.
MPEG is a lossy compression method, which means data (image detail) is permanently dis- carded during the compression process.
MPEG uses the same intraframe coding method as JPEG for individual frames, but it
