TECHNICAL DESCRIPTION
12
4-3 Recorder Signal Processing
< VIC4 >IC2301
•
The VIC, MI-COM, DIF INTERFACE and VIDEO INTERFACE circuits are integrated on a single semiconductor chip.
•
A/B DATA
: Input in camera mode. B DATA is output and A DATA is input at playback. (DIGIC DV digital effect circuit is
used at playback.)
The video data and signals input to VIC4 are subjected to digital VCR format signal processing. Audio data,
subcode data and ITI data are also created at VIC4, and these signals are output to VRP2 as 41.85 Mbps data of
DV format.
•
DIF
: After conversion to digital data conforming to IEEE1394 standard, the data is output at DV terminal. At digital
input, the data enters VIC4 signal processing circuit via the opposite route.
< VRP2 >IC2000
Recording data of 41.85 Mbps output from VIC4 is amplified at VRP2, and is recorded on magnetic tape while undergoing head
switching of CH-1, CH-2 with a switching pulse. At playback, the head output signal is amplified and sent to VIC4.
