• Writing data to external USB3.0 device
The record data saved in the DDR memory is DMA-transferred to the USB3.0 HOST controller IC (IC201) on the
DIO-97 board with the PCIe interface and is written to the external USB3.0 device.
Copying SxS memory card data to the external USB3.0 device
Upon a DMA request from the Linux CPU on the CPU board, data is read from the SxS memory card (CN901, CN902)
on the EC-76 board. The read data is converted to SATA signal data by the PCI/PCIe Bridge ICs (IC206, IC406), ATA/
PCI Bridge ICs (IC202, IC402), and SATA/ATA Bridge ICs (IC201, IC401) on the DIF-221 board. Then the SATA
signal data is sent through the CN-3594 board to the HPR-46 board.
Furthermore, the data is DMA-transferred to the DDR memory on the CPU board through the PCIe / SATA Bridge IC
(IC2701) on the HPR-46 board with the PCIe interface.
At the same time, the CPU board DMA-transfers the data saved in the DDR memory to the USB3.0 HOST controller
IC (IC201) on the DIO-97 board with the PCIe interface and writes the data to the external device.

Playback System
The playback data read from the SxS memory card (CN901, CN902) on the EC-76 board is sent to the CPU board on
the HPR-46 board. Then the playback data is sent from the CPU board to PIERe on the HPR-46 board through PCI-
Express and is written to the PIERe SDRAM.
The audio playback data stored in the PIERe SDRAM is sent to the VAX FPGA (IC200) in which CH-1 to CH-8 audio
signals are multiplexed. The multiplexed audio signals are sent to PB/MONI AUDIO DSP in which signal processing
(including digital JOG sound processing, playback level control, and mute processing) is performed.
The processed playback audio signals are sent back from PB/MONI AUDIO DSP to VAX as audio signals for HD-SDI
OUT1, 2, SD-SDI OUT1, 2, and ANALOG AUDIO OUT.
CH-1 to CH-8 audio record signals are multiplexed in VAX, and are then sent to PB/MONIAUDIO DSP where signal
processing (including level control, delay processing, and mute processing) is performed.
The processed audio signals are sent back from PB/MONI AUDIO DSP to VAX as audio signals for MONITOR HD-
SDI OUT, MONITOR SD-SDI OUT, MONITOR ANALOG AUDIO OUT, and HEADPHONES OUT.
The playback proxy audio data stored in the PIERe SDRAM is sent to DEC PROXY AUDIO DSP (IC1903, IC1904)
where expansion processing is added (opposite to recording). Then the expanded data is sent to APROC. Furthermore,
the signal is multiplexed and is input to PB/MONI AUDIO DSP1 where the signal and the main-line playback digital
audio signal are switched and are used as needed such as at the time of shuttle playback.
Analog audio output
The playback digital audio data output from VAX is sent to the audio D/A converter (IC301) on the AU-351 board for
conversion to analog audio signal. The analog audio signals are output from the AUDIO OUT connector (CN400, 500/
AU-351 board).
HDSDI output
The playback digital audio data output from VAX is input to the ROVO via the CN31/VPR-118 board. The audio data
are multiplexed with the playback digital video data in ROVO. Then the multiplexed data undergoes parallel/serial
