In this way it is easy to realise a media player for presentations and
exhibitions, which can be activated by the public through the GPI
buttons. Even after a power cut or switching the machine off and on
settings are stored and the machine will resume its function.
The respective GPOs indicate the selection of clip 1, 2, 3 or 4.
Setting PLAY,STOP, CLIP-, CLIP+ defines the GPIs as follows:
GPI_1: PLAY puts the machine into play
GPI_2: STOP stops the transport
GPI_3: CLIP- decreases current clip number
GPI_4: CLIP+ increases current clip number
MENU 075 [+] / [–] KEYS FUNCTION
In this menu the function of the
[+] and [–] keys during stop mode can
be defined.
"During stop mode" means the machine shows a still picture and the
menu is switched off.
Selection STEP FWD/REVERSE allows you to step one frame ahead
and reverse respectively.
The function INC/DEC CLIP NUMBER changes the current clip
number without using a menu.
MENU 080 RECORD SYNC REFERENCE
The reference sync for the bonsaidrive can be separately selected for
playback and record mode.
Select the sync reference for record mode in menu RECORD SYNC
REFERENCE.
The setting VIDEO INPUT uses the video input signal as sync
reference. A digital PLL guarantees a stable lock even from very
unstable or inaccurate video sources e.g. from a VHS-video tape
recorder.

The colour subcarrier frequency of the composite video output is
asynchronously controlled for errors larger than +/- 5 ppm.
In this way errors of up to 150 ppm in the video source can be
compensated.
The audio section of the recorder is synced to the video input and so
the word clock output on C2 can be used to synchronise other audio
equipment.
When synchronising from the video input, only the video frequency is
used. Field and line phase are not synchronised at the output.
The setting SYNC INPUT uses external house sync on input C3
(Sync Input) to synchronise the recorder in record mode.
When using this setting the input video must be synchronised to the
same house sync as well.
DIRECT VIDEO I/O MODE passes the video input signal data direct
to the video outputs. This mode is saving system memory throughput
and should be used for the "CAPTURE WHILE RECORD" functions
with bonsaiLAN networking option.
When entering EE or record in this mode the picture contents are
moving some seconds from a left or right offset into the centre. This
appears only on the monitoring output and does not affect the
recording on the harddisk.
MENU 081 PLAYBACK SYNC REFERENCE
In play mode the recorder can be synced internally or to an external
house sync (video black and burst signal).
The setting INTERNAL synchronises the internal audio clocks and
video to a very stable VCXO.
The word clock output has absolute reference quality and can be
used to synchronise all professional audio equipment.
