3.8.1 ON AIR Character Keyer mode
Select ON AIR MODE ON to blank all the Charater windows when the VTR Status is
Play or VAR, or when the ON AIR remote control input is closed to ground.
When ON AIR MODE OFF is selected, the Charater windows ignore the VTR Status and
the ON AIR remote control input.
3.9 PARALLEL REMOTE CONTROL FUNCTIONS
For ease of wiring multiple 5010-SIE units together where the parallel inputs must be shared, loop
through outputs have been provided for each of the GPI inputs. The loop through output for pin 2 is pin
9 and for pin 3 is pin 5. See section 2.1.6.
4.3 CIRCUIT DESCRIPTION
4.3.7 High Speed LTC Reader (5200-32) & (5200-34)
Incoming LTC is decoupled and amplified by U9, U10 and associated components to provide a
regenerated reader data signal at the LR test point. This digital representation of the LTC is fed to the
LCA where a series of timing pulses generated by the LCA are used to properly decode 0 and 1 bits.
The LTC data is extracted by the LCA and is shifted into one half of shift register U26. The LCA
generates an LTC RDY signal to the MCU when it has received one frame of data.
information derived from the last bit of the sync word is also fed to the MCU. A valid reader sync word
toggles a flip flop in the LCA which enables the other half of shift register U26 to collect data from the
next frame while the MCU is unloading data from the frame just completed through the LCA.
