proportion of analog stereo TV broadcasts. If you watch television or enjoy VHS HiFi movies, you'll use Dolby Pro Logic surround sound. Dolby Pro Logic II-movie and Pro Logic II-music. These new decoding systems derive 5.1 channels instead of the conventional 4 channels of Dolby Pro Logic surround sound. These are decode-only systems. By design, there is no Pro Logic IImovie or Pro Logic II-music encoding for source material. dts® 5.1-channel surround sound. Another digital surround sound format, used as an option for DVD movie sound tracks and for music disks. dts 96/24. The DVD-Video standard offers the possibility of a dts 5.1-channel signal encoded at a 48 kHz sampling rate. However, dts has created a way to extend the sampling rate to 96 kHz while retaining full backwards compatibility. Older decoders can handle the new discs (although without the benefit of the 96 kHz sampling rate). Newer decoders can deliver the extended frequency response and heightened realism of the 96 kHz signal. dts ES discrete 6.1 and dts ES matrix 6.1. These systems add a Surround Back channel. In the "discrete" case, it's a completely separate channel. In the "matrix" case, it's specially encoded into the other surround channels, then regenerated by the receiver. dts Neo6:cinema and dts Neo6:music. These decoding systems derive six channels from two-channel material. These are decode-only systems. By design, there is no Neo6:cinema or Neo6:music encoding for source material. A/V Receivers In many respects, the A/V receiver is the brains of your home theater system. It's where you connect and select all your entertainment sources. It's where the surround sound signals are decoded into their separate speaker channels, and where those channels are amplified to drive the full range speakers. (Subwoofers typically have their own amplifiers built in.) The Sony Guide to Home Theater 30
