completion of encoding the actual value of stop time, including samples, will be
shown in the TC Stop Time display. This samples value can then be used to offset
the next piece of encoded material, if necessary, to maintain A/V sync. For more
information consult Appendix B.
Timecode control can be entered only when the following conditions are met:
• Input Format is set to PCM.
• Multiplex Mode is disabled.
• Timecode controlled preset recalls are not pending.
The time stamp must be enabled for timecode to exist in the bitstream. For further
information, see Appendix B.
4.2.2 Metadata Control
This menu controls the source for metadata for the DP569 and what to do in the
situations where the metadata disappears.
The submenus are:
• Metadata Source
• Override Params
• Reversion Mode
• Reversion Preset
Metadata Source
Chooses the source or origin of the metadata values used in the encoding process.
Internal uses the current values as defined in the Metadata Params menus, these
values can be modified at any time. Choosing a specific program number uses the
metadata contained within that program from the metadata stream connected to the
Metadata port.
Override Params
When using metadata from a chosen external program, this setting allows either the
dialogue level and/or compression profile parameter to be replaced by the internal
metadata parameter setting.
Reversion Mode, Reversion Preset
These parameters determine what happens when the external metadata source, if
selected, is interrupted.
• Last Used continues encoding using the last values set by the external source.
• Preset continues encoding using the values contained in the chosen Reversion
preset.
