This standard defines the mapping and labeling of channels for the Digital Cinema Distribution Master (DCDM) audio in a digital cinema audio system to aid the identification and location of channels. This will allow uniform expression and communication of source audio channels to digital cinema playback loudspeakers. This standard is not intended to define the suitability of these channels for a particular sound track nor to specify that all channels described herein will be used. It is quite likely however that additional channels will be used in future systems; these are therefore included in this standard as labels only. Channel maps define channel usage of common legacy systems.
