Dolby Pro Logic IIz is an extension of Dolby Pro Logic IIx that provides two additional “front height” output channels. These two channels drive two speakers positioned above the front left and right speakers. Dolby Pro Logic IIz can be used to expand 5.1-channel material or even stereo material to be reproduced by “7.1 Height” or “9.1” systems.The Dolby Pro Logic IIz Decoder delivery from ADI consists of the “Dolby Pro Logic IIz Decoder” and “Dolby Pro Logic IIx Decoder” software modules. These are compliant with Dolby specifications and have been rigorously tested. Both modules have been highly optimized to run on the Analog Devices SHARC processor family and have been certified by Dolby to be used for Dolby Pro Logic IIz processing. The Dolby Pro Logic IIz decoder operates on PCM data received either through analog/digital input channels or from a decoder module. The Dolby Pro Logic IIz Decoder takes up to 7.1 input channels and outputs up to 9.1 audio channels. It contains a standard C-callable ‘push’ API with the added flexibility using ‘pull’ (or ‘poll’) by adding a light wrapper. The module has no dependencies on processor peripherals or registers, adding greater system flexibility and ease of use. The Dolby Pro Logic IIz Decoder on SHARC is provided with an API consistent with other audio decoder and post-processing modules produced by ADI. In addition to the object libraries for Dolby Pro Logic IIx and Dolby Pro Logic IIz, the Dolby Pro Logic IIz release package includes source code for the Dolby Pro Logic IIz-specific post-processing functions additional to Dolby Pro Logic IIx. This gives customers the option of further optimizing the code for tighter integration with their system.
