Central Control Unit CCU
This unit controls all substantial functions of the DCR 6024/ 6128/6000. All com-
mands from the Control Panel and all messages to the Control Panel have to pass
this unit. CCU takes over the status information management for the entire control
system centrally. Therefore all control setup data has to be stored in this unit. For
this purpose several nonvolatile store devices are used.The CCU software controls
and monitors following subunits:
RF-Processing
Cue Track Processing
Head Switch Logic
Wave Form Monitor
Nonvolatile Memory
Temperature Sensor (System control unit BY 5160)
Front Panel Display
Motor Control Unit MCU via Dual Port RAM
Timecode Unit TCU via Dual Port RAM
Gateway GW (Serial I/O Unit) via Dual Port RAM
Some parts of the system CCU software is divided into two parts. One is the DTV
version, the other one is the data version. After power up of system the processor
type is detected via iMCS and depending on the response application specific soft-
ware parts are loaded.
Gateway GW (Serial I/O Unit) (DTV Mode)
All external standard control systems are connected to the DCR 6024 via this unit.
Different control dialects are converted into the iMCS data format and exchanged
with CCU via a Dual Port Ram. Following remote interfaces are available:
REM1 (ES- Bus with limited implementation).
ES-Bus-Interface specified by EBU Tech.3245–
E Supplement 1 and Supplement 2.
REM2 IN RS422 standard SONY VTR protocol 38.4 K Baud.
REM2 OUT Serial RS-422 Control Interface according to standard SONY
VTR protocol for controlling a Slave-(Playback) VTR which does not
have an iMCS interface.
Timecode Unit TCU
The timecode unit includes timecode reader and timecode generator. All com-
mands and messages to the TCU are passed via a Dual Port Ram. The generator
circuit provides two output signals. One signal is recorded on tape according to the
specified footprint and the other output is passed to the XLR-output connector. The
output signal is delayed by a FIFO in order to match the timing of the video signal.
A real time clock generator is used as time base for the timecode generator. This
device is connected to the battery so that the clock keeps running while power is
switched off.The timecode reader circuit can be switched to the tape signal from
tape or to the signal from the XLR TC-In connector for synchronization purposes.
