The CAMERA MICON (camera μ-processor: IC500) performs the overall control over the entire camera system and is con-
trolled by the camera system controller (IC2900).
Peripheral ICs of the CAMERA MICON (camera μ-processor: IC500) are FLAH ROM (IC413) and SDRAM (IC414).
3. Video Signal System
DPR-311 Board
The digital video (Y/C) signal output from the camera signal processor IC (IC200) enters the baseband processing IC
(IC600).
The baseband processing IC (IC600) performs the overall baseband processing of video and audio signals with a single chip
IC containing the various scaler functions (supporting the multiple format outputs), various OSD functions, PLL function
(54 MHz → 74 MHz) and CPU.
The baseband processing IC (IC600) provides the following outputs:
. HD/SD Component (digital): To TX-131 board
. HD/SD Component (analog): To TX-131 board
. Composite (analog): To TX-131 board
. LCD signal (digital): To LCD module
. EVF signal (analog): To DR-644 board
The input/output signals of the baseband processing IC (IC600) are the following signals:
. MPEG encoder/decoder I/F signal (digital): To IC1500
. Audio I/F signal (digital): To IC1300
Peripheral circuits of the baseband processing IC (IC600) are the master clock 54 MHz VCXO (X800) control circuit
(IC803, IC804, IC806, IC807, IC808) and the Mobile DDR SDRAM memory (IC1100, IC1101).
Peripheral circuits of the built-in CPU are FLASH ROM (IC1003) and SDRAM (IC1000).
The baseband processing IC (IC600) is controlled by the system controller (IC2900). The LCD driver IC, the EVF driver
IC, SDI Co-pro, the audio system and the power save control of the output systems are controlled by the built-in CPU
inside IC600.
4. Media Recording and Playback
DPR-311 Board
Output from the baseband processing IC (IC600) is input into the MPEG encoder/decoder (IC1500).
The MPEG encoder/decoder (IC1500) is the single-chip MPEG Codec IC that encodes and decodes both the high-quality
HD video signal and audio signal in real-time. It has various interfaces with signals such as MPEG video, video input/
output, MPEG audio, audio input/output, bit stream input/output, and interface with the host.
IC1500 output is then input into LSI (IC1600) for AVIT signal processing.
LSI (IC1600) for AVIT signal processing contains the built-in CPU and has interfaces for DDR2 SDRAM memory (IC1800,
IC1801), PCI bus, PCI-Express bus, I/O for IC1500, and serial communication with system controller (IC2900).
IC1600 is also connected to the NOR-type Flash ROM (IC1901) to read the CPU program in the IC1600 during initial startup.
LSI (IC1600) for AVIT signal processing is controlled by the system controller (IC2900), in the same way as other main
devices, and provides the following types of functions: video/audio stream control, access to the SxS memory card, mass
storage operations when connected to USB and HDV device controls when connected to i-LINK.
Explanation of peripheral devices
<SxS memory card slot>
Two memory card slot boards (EC-68) are connected to the dual channel PCI-Express signals coming from IC1600 through
a 0.4 mm pitch, 30-pin fi ne coaxial cables connected to CN2400 and CN2401.
Furthermore, dual channel USB host signals output from USB host controller (IC2300) are connect to the EC-68 board
through fi ne coaxial cables just as with the PCI-Express signals.
IC2300 is controlled by PCI bus from IC1600.
