It seems that there are a few questions about DPL and NICAM. I hope the following helps, although it is not the only answer. NICAM (near instantaneous companding audio multiplex) is a method of delivering near CD (35KHz 12 Bit ) stereo audio. DPL (Dolby Pro Logic www.dolby.co.uk) is a method of encoding 4 channels of audio into 2 by using an audio phasing encoding system. See Dolby for a technical breakdown. You can listen to the broadcast as normal in stereo but a DPL decoding circuit can be used to extract the 2 other channels. So a NICAM broadcast can be used to send a DPL soundtrack. Do not assume that all stereo audio has been process in DPL. Please do not flame this post, as it is only to help.
