MVX250i E, MVX200i E, MVX200 ETECHNICAL DESCRIPTION134-3 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 isused 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 ofDV format.• DIF : After conversion to digital data conforming to IEEE1394 standard, the data is output at DV terminal. At digitalinput, the data enters VIC4 signal processing circuit via the opposite route.< VRP2 >IC2000Recording data of 41.85 Mbps output from VIC4 is amplified at VRP2, and is recorded on magnetic tape while undergoing headswitching of CH-1, CH-2 with a switching pulse. At playback, the head output signal is amplified and sent to VIC4.Fig. 10AV JACKS TERMINALCVFLCDLCDIC1103DIGICDVVIDEOINTERFACEA DATAB DATAR,G,BD/A75ΩDRIVE A/DIC2302SDRAMREC/PBPROCESSECCCOMPRESSION/DEMOD.BUSIC2301VIC4VIC BLOCK DIF BLOCKMI-COM.
