Because the proxy video data is used as the video data during the SEARCH operation, it is sent from PIER SDRAM to
LVIS via PIER. The proxy video data receives the decode processing inside the LVIS, up-converted to the HD playback
video signal.
HDSDI output
The HD playback video signal and the HD playback video signal that is up-converted by SD playback video signal inside
LVIS are sent to VAX (IC206) after the OSD screen with GUI display is switched and the HD Video Process is performed
in LVIS. After a part of the ANC data is written at this point, the HD playback video signal is sent to the RX-93 board on
the VPR-99 board with the audio signal.
After characters for superimposing are added in the FPGA (IC300) on the RX-93 board, and the video signal, audio signal,
and the ANC data (LTC, VITC, UMID, essence mark) are multiplexed, the HD playback video signal undergoes serial/
parallel conversion and output from the RX-93 board connector (CN502, 503) as the 1.5 Gbps HDSDI signal, and then
output to the outside from the HDSDI OUTPUT connector on the rear.
LCD monitor output
The HD playback video signal is output from LVIS to VAX, in which characters for superimposing are added. The signal
undergoes pixel conversion to fit for the resolution to be displayed on the LCD monitor. Then, it is sent to the Graphic
Controller on the KY-624 board through the harness from the connector (CN1) and displayed on the LCD monitor.
SDSDI/composite output
The HD playback video signal and the SD playback video signal that is down-converted by HD playback video signal
inside LVIS are sent to VAX as the SD playback video signal after it is down-converted inside LVIS and the SD Process
processing is performed. After a part of the ANC data is written at this point, the SD playback video signal is sent to LUNA
(IC100) on the VPR-99 board with the audio signal. After characters for superimposing are added in LUNA and the video
signal, audio signal, and the ANC data are multiplexed, the SD playback video signal undergoes serial/parallel conversion
and output to the outside from the SDSDI OUTPUT connector (CN3, 4).
The SD playback video signal that is sent from LUNA to the video encoder (IC300) is encoded into the composite video
signal and output to the outside from the COMPOSITE OUTPUT connector (CN5).
i.LINK output
The PIER SDRAM playback video data and the playback proxy video data are sent from PIER to the FAM Accelerator
(IC1201) through the PCI BUS. Then, the playback video data are sent from the connector (CN2) through the harness to the
connector (CN100) of the NET-4 board via the i.LINK PHY (IC1) of the IF-1073 board on the HPR-23 board.
Network output
The PIER SDRAM playback video data and the playback proxy video data are sent from PIER to the Ethernet interface IC
(IC1300) on the NET-4 board through the PCI bus via the PCI bridge inside PHOT (IC801). Then, the playback video data
is converted into the bit stream by the Ethernet interface IC and output from the network connector (CN2).
