Displaying the Dolby PPM window
As stated above, the Dolby-E audio and the associated metadata are encoded on a pair
of embedded audio channels, potentially alongside PCM audio. The first step is therefore
to identify which pair of channels is carrying the Dolby-E data.
The relevant pair of channels can readily be determined from the Embedded PPMs
display where the channels will be picked out by the in-bar message ‘DATA’. (The
channels will also typically be shown as ‘clipped’ in this display.)
The required channel pair may then be selected by clicking on it in the Embedded PPMs
display. The chosen pair will then be shown highlighted to indicate that it has been
selected. In addition, it is advisable to ensure that the Decode type for this channel pair is
specified as Dolby-E. This is done by checking that the Decode Type for the channel pair
is set to Dolby-E in the Audio Configuration dialogue for this PPMs window (see page
91).
The audio levels encoded within the Dolby-E data may then be displayed by calling up
the Audio Dolby-E PPMs window, either by selecting this from the main Window menu or
by clicking on the Audio PPMs icon and selecting the Dolby-E option from the short
menu that then appears.
Options menu
The Options menu associated with the Dolby Audio PPMs display includes the above
Configuration, Reset Peak and Hold and Graticule options, but does not include
any ‘Surround-sound view’ option as the appropriate view is automatically selected
based on the Dolby data encoded alongside the audio.
