One of the characteristics of Dolby True HD is to provide amazing studio master sound quality through the next generation of optical media, bringing you a real HD entertainment experience. Provides more independent channels and perfect surround sound than ever before. Compatible with current and future A/V receivers and Home Theater Suite (HTIBs). When you switch to another dolby digital and Dolby TrueHD program, the conversation can keep the same volume. Dynamic range control (night mode) allows you to play audio on demand, reduce the peak volume (without sudden loud sound), and experience all the details in the audio track, so that you can enjoy strong surround sound at night without disturbing others. As the mandatory audio standard of HD DVD and the optional audio standard of Blu-ray disc, the next generation of HD disc player will be compatible with the current A/V receiver. Whether you have a traditional A/V receiver with Dolby digital technology or a new A/V receiver with HDMI interface or external multi-channel linear input, Dolby TrueHD technology can ensure high-quality compatible playback modes. DTS-es is called "extended surround sound" and is divided into DTS-es separation 6. 1 and matrix 6. 1. DTS-es is an enhanced version of DTS5. 1 When DTS-es is decoded separately at 6. 1, the decoder takes the core part and the extended part of DTS signal as a whole, and the surrounding left and right channels can be recovered by arithmetic subtraction. The surround sound center (also called the back surround sound center) is directly decoded, so a completely separated 6. 1 sound field can be generated. However, when decoding the matrix 6. 1, only the core part of the signal is considered and the extended part is ignored. However, due to the patented post-processing es matrix module of DTS, an "extended surround" sound field of 6. 1 can still be generated. It can be seen that there are differences between the two decoding methods of es.
