Glossary

Analogue: Sound that has not been switched into numbers. Analogue sound varies, while digital sound has specifi c numerical values. These sockets send audio through two channels, the left and right.

Aspect ratio: The ratio of vertical and horizontal sizes of a displayed image. The horizontal vs. vertical ratio of conventional TVs is 4:3, and that of wide-screens is 16:9.

AUDIO OUT Sockets: Red and white sockets on the back of the DVD system that send audio to another system (TV, Stereo, etc.).

Bit rate: The amount of data used to hold a given length of music; measured in kilobits per second, or kbps. Or, the speed at which you record. Generally, the higher the bit rate, or the higher the recording speed, the better the sound quality. However, higher bit rates use more space on a disc.

Chapter: Sections of a picture or a music piece on a DVD that are smaller than titles. A title is composed of several chapters. Each chapter is assigned a chapter number enabling you to locate the chapter you want.

Component Video Out sockets: Sockets on the back of the DVD system that send high-quality video to a TV that has Component Video In sockets (R/G/B, Y/Pb/Pr, etc.).

Disc menu: A screen display prepared for allowing a selection of images, sounds, subtitles, multi-angles, etc. to be recorded on a DVD.

DivX 3.11/4.x/5.x/6.x: The DivX code is a patent-pending,MPEG-4 based video compression technology, developed by DivX Networks, Inc., that can shrink digital video to sizes small enough to be transported over the internet, while maintaining high visual quality.

Dolby Digital: A surround sound system developed by Dolby Laboratories containing up to six channels of digital audio (front left and right, surround left and right, centre and subwoofer).

Dolby Digital EX: A surround sound system developed by Dolby Laboratories containing up to seven channels of digital audio (front left and right, surround left and right, centre front and rear subwoofer).

Dolby Surround Pro Logic II: It is an improved matrix decoding technology that provides better spatiality and directionality on Dolby Surround programme material, provides a convincing three dimensional sound fi eld on conventional stereo music recordings and is ideally suited to bring the surround experience to automotive sound. While conventional surround programming is fully compatible with Dolby Surround Pro Logic II decoders, soundtracks will be able to be encoded specifi cally to take full advantage of Pro Logic II playback, including separate left and right surround channels. (Such material also compatible with conventional Pro Logic decoders).

DTS: Digital Theatre Systems. This is a surround sound system, but it is different from Dolby Digital. The formats are developed by different companies.

HDMI: High-Defi nition Multimedia Interface (HDMI) is a high-speed digital interface that can transmit uncompressed high defi nition video and digital multichannel audio. It delivers perfect picture and sound quality, completely free from noise. HDMI is fully backward-compatible with DVI.

As required by the HDMI standard, connecting to HDMI or DVI products without HDCP (High-bandwidth Digital Content Protection) will result in no Video or Audio output.

HDCP (High-bandwidth Digital Content Protection) is a specifi cation that provides a secure transmission of digital contents between different devices (to prevent unauthorised copyright).

JPEG: A very common digital still picture format. A still picture data compression system proposed by the Joint Photographic Expert Group, which features small decrease in image quality in spite of its high compression ratio.

MP3: A fi le format with a sound data compression system. “MP3” is the abbreviation of Motion Picture Experts Group 1 (or MPEG-1) Audio Layer3. By using the MP3 format, one CD-R or CD-RW can contain about 10 times more data then a regular CD.
