external genlock with digital signal processor and RGB splitter for consumers and semi-professional use, connected to the RGB and joystick port of the Amiga
phase-locked chroma subcarrier
integrated RGB splitter to enhance video quality and video digitizer support
allows color correction via controls at the front panel - color, contrast and brightness
supported effects: fading, superimposing, inverse superimposing - controllable via controls at the front panel, effects can be run automatically
input connectors:
1× RCA Composite Video In
1× Mini DIN Y/C (S-VHS) Video In
1× 9 pin RGB Amiga Video Input
1× Joystick Input
connection to Amiga is done via shielded RGB cable with a metal box containing an oscillator board
output connectors:
1× RCA Composite Video Out
1× Mini DIN Y/C (S-VHS) Video Out
1× 9 pin RGB Bypass to attach a monitor
1× RCA Composite Digitizer Video Out (RGB splitter output)
outputs are buffered and can be used simultaneously
digitizer output allows connecting a slow scan video digitizer that digitizes in 3 passes (red, green and blue) - 3 LEDs display the current channel, the channel switching is done automatically by the software via joystick port
switch to disable interlace mode - the image is shown flicker-free with reduced resolution
'Professional' version provides an additional RGB Bypass output for a monitor, a special synchronization circuit on the oscillator board for increased image stability, and two automatic wipe effects
measured composite video bandwidth is 2.5 MHz, measured Y/C bandwidth 4 MHz
for the 'Professional' version, the bandwidth is increased to 3.5 MHz (composite) resp. 4.5 MHz (Y/C)
limitations in video performance: black level does not reach 0.3V, blue and yellow levels are too high
both can be installed internally or externally, to the internal or external DB25 parallel port
the Digi-Gen has to be connected to the Amiga's parallel and joystick ports
when the the digitizer is installed internally, the external DB25 port acts as a parallel passthrough port - the DI/PR switch selects between the digitizer and passthrough
when installed outside, the digitizer is fed with composite video signal through the DI output connector (RCA)
