Glossary Album Section of a music or picture piece on a DATA CD or DATA DVD containing MP3 audio tracks or JPEG image files. Chapter Subdivision of a title on a DVD VIDEO. A title is composed of several chapters. Dolby Digital This sound format for movie theaters is more advanced than Dolby Surround Pro Logic. In this format, the surround speakers output stereo sound with an expanded frequency range and a subwoofer channel for deep bass is independently provided. This format is also called "5.1" because the subwoofer channel is counted as 0.1 channel (since it functions only when a deep bass effect is needed). All six channels in this format are recorded separately to realize superior channel separation. Futhermore, since all the signals are processed digitally, less signal degradation occurs. Dolby Pro Logic II This technology converts 2 channel stereo recorded audio into 5.1 channels for playback. There is a MOVIE mode for movies and MUSIC mode for stereo sources such as music. Old movies encoded in traditional stereo format can be enhanced with 5.1 channel surround sound. Movie mode The Movie mode is for use with stereo television shows and all the programmes encoded in Dolby Surround. The result is enhanced sound field directionality that approaches the quality of discrete 5.1-channel sound. Music mode The Music mode is for use with any stereo music recordings, and provides a wide and deep sound space. Dolby Surround Pro Logic As one method of Dolby Surround decoding, Dolby Surround Pro Logic produces four channels from two-channel sound. Compared with the former Dolby Surround system, Dolby Surround Pro Logic reproduces left-to-right panning more naturally and localizes sounds more precisely. To take full advantages of Dolby Surround Pro Logic, you should have one pair of surround speakers and a center speaker. The surround speakers output monaural sound. DTS Digital audio compression technology that the Digital Theater Systems, Inc. developed. This technology conforms to 5.1-channel surround. The surround channel is stereo and there is discrete subwoofer channel in this format. DTS provides the same 5.1 discrete channels of high quality digital audio. The good channel separation is realized because the all channel data is recorded discrete and processed in digital. DVD VIDEO A disc that contains up to 8 hours of moving pictures even though its diameter is the same as a AUDIO CD. The data capacity of a single-layer and singlesided DVD VIDEO, at 4.7 GB (Giga Byte), is 7 times that of a AUDIO CD. Furthermore, the data capacity of a dual-layer and single-sided DVD VIDEO is 8.5 GB, a single-layer and double-sided DVD VIDEO 9.4 GB, and a duallayer and double-sided DVD VIDEO 17 GB. The picture data uses the MPEG 2 format, one of the worldwide standards for digital compression technology. The picture data is compressed to about 1/40 of its original size. The DVD VIDEO also uses variable rate coding technology that changes the data to be allocated according to the status of the picture. The audio data is recorded in Dolby Digital as well as in PCM, allowing you to enjoy more realistic audio presence. Furthermore, various advanced functions such as the multi-angle, multilingual, and Parental Control functions are provided with the DVD VIDEO. Additional Information continued 91US
