English Glossary Analog audio: An electrical signal that directly represents sound. In contrast, digital audio can also be an electrical signal, but is an indirect representation of sound. See also Digital audio. Aspect ratio: The width of a TV screen relative to it is height. Conventional TVs are 4:3 (i.e., the screen is almost square). Widescreen models are 16:9 (the screen is almost twice as wide as its height) Chapter: Just as a book is split up into several chapters, a title on a DVD disc is usually divided into chapters. See also Title. AUDIO OUT jacks: Jacks on the back of the DVD System that send audio to another system (TV, Stereo, etc.) Bite rate: The amount of data used to hold a given length of music; measured in kilobits per seconds, or kbps. Or, the speed at which you record.Generally, the higher the bite rate,or the higher the recording speed, the better the sound quality. However, higher bite rates use more space on a disc. Disc menu: A screen display prepared for allowing of selection of images, sound, subtitle,multi-angles etc. recorded on the DVD. Digital audio: An indirect representation of sound using numbers. During recording, the sound is measured at discrete intervals (44, 100 times a second for CD audio) by an analog-to -digital converter, generating a stream of numbers. On playback, a digital-to-analog converter generates an analog signal based on these numbers. See also Sampling frequency and Analog audio. Dolby® Digital: A system developed by Dolby Laboratories that compresses digital sound. It works with stereo (2ch) or multi-channel audio. DTS®: (Digital Theater System) DTS is a Multi-channel surround sound system, but it is different from Dolby Digital. Both formats were developed by Digital Theater Systems, Inc. JPEG: (Joint Photographic Experts Group) JPEG is a method of compressing still image files. You can copy JPEG files on CD-RW / R discs from a computer and play back the files on this unit. MP3: (MPEG Audio Layer 3) MP3 is a method of compressing files. You can copy MP3 files on CD-RW / R discs from a computer and play back the files on this unit. Multichannel: DVD is specified to have each sound track constitute one sound field. Multichannel refers to a structure of sound tracks having three or more channels. Parental control: A function of the DVD to limit playback of the disc by the age of the users according to the limitation level in each country. The limitation varies from disc to disc; when it is activated, playback will be prohibited if the software's level is higher than the user-set level. PBC (Video CD only): (Playback Control) This function enables you to play back interactive software using a menu screen. See also Title. Progressive scan: It displays all the horizontal lines of a picture at one time, as a signal frame. This system can convert the interlaced video from DVD into progressive format for connection to a progressive display. It dramatically increases the vertical resolution. PCM: (Pulse Code Modulation) PCM is a format that converts audio into digital data. It is mainly used for Audio CDs and DAT. This unit can play back sounds as realistic as possible by converting even compressed Dolby Digital and MPEG audio to PCM. Region code: Regions associate discs and players with particular areas of the world. This unit will only play back discs that have compatible region codes. You can find the region code of your unit by looking on the rear panel. Some discs are compatible with more than one region (or all regions). Sampling frequency: The rate at which sound is measured by a specified interval to turn it into digital audio data. The number of samples in one second is defined as the sampling frequency. The higher the rate is, the better the possible sound quality. Title: (DVD) A collection of chapters on a DVD. See also chapter. (Video CD) The contents of a Video CD. When playing back a Video CD with the PBC function, the title menu will appear automatically. Track: Audio CDs and Video CDs use tracks to divide the contents of a disc. The DVD equivalent is called a chapter. See also Chapter. 24
