Vitc Reader - Merging Pyramix User Manual

General
These are the general settings on which all other time code parameters are based. The TC Source combo box
offers a choice of Auto , LTC , VITC or External .
Auto looks at all the sources and uses them in the order: LTC > STC > VITC
Format
Shows the current TimeCode format selected from the drop-down list. Pyramix supports the following formats:
Film 23.98 fps, Film 23.98 fps Drop, Film 24 fps, PAL 25 fps, NTSC 29.97 FPS, NTSC 29.97 fps Drop, SMPTE 30 fps,
SMPTE 30 fps Drop.
Reference
The Reference drop-down menu sets the time code source when TimeCode is selected as the digital audio Sync
Source in Settings > Mixer Settings : I/O page Sync Source .
The Reference pull-down list allows for choosing between clocking the system's audio engine to an Internal refer-
ence derived from the audio board's time code generator chip, or a clock derived from the time code input port on
the optional Video/TC interface. To set the digital audio word clock source, see the I/O panel in the Virtual Studio
Settings window.
TC Source
Shows the source of Timecode that will be used to synchronize Pyramix playback or to generate the timestamp
when an audio file is digitized. A drop down list offers the following choices:
Internal uses the code from the internal time code chip on the audio board.
VITC uses code from the Vertical Interval Time Code (VITC) input on the optional Video/TC interface bracket /
breakout cable.
LTC uses the Linear Time Code (LTC) input on the Video/TC interface bracket to derive
Auto Pyramix automatically uses any valid Timecode location reference from an Internal, VITC, LTC or External
Timecode source.
External uses the code from the External TC reader source.
External TC reader
Shows the current value of the External Time Code reader. The drop-down list offers a choice of Virtual Transport
and all external machines installed and enabled in the Settings > All Settings > Remote Control > Machine
page.
LTC reader
Shows the current value of the Linear Time Code (LTC) reader chip. I.e. the external LTC input.
LTC Generator
Mykerinos boards have a Linear Time Code generator.
Output Level (dBV)
Shows the current LTC output level in dBV. The drop-down list offers a choice of output level from -24dBV to
+9dBV in 3dBV increments, or it can be switched Off.
Off when stopped
When checked Pyramix mutes the LTC output when stopped. If not checked, it continues to output it's actual posi-
tion. (static Timecode) Certain video and audio machines cannot handle static Timecode.

VITC Reader

Mykerinos boards are capable of reading Vertical Interval Timecode encoded in a lines of a video signal. VITC has
the advantage of being accurate and readable even when the video is stationary.
Video Input
These check buttons allow the choice of which of the two video inputs will be used for the VITC signal.
