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 programs 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 developed by DTS, Inc. 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 an AUDIO CD. The data capacity of a single-layer and single- sided DVD VIDEO, at 4.7 GB (Giga Byte), is 7 times that of an AUDIO CD. Furthermore, the data capacity of a dual- layer and single-sided DVD VIDEO is
8.5GB, a single-layer and double-sided DVD VIDEO 9.4 GB, and a dual-layer 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.
