Media Recording/Playback System - Sony PMW-200 Service Manual

The baseband signal processed by T-ONE is sent to the router IC ANDV (IC1700), and is then distributed to inputs and
outputs.The following table lists inputs and outputs of the baseband processing IC T-ONE.
Signal name and input/output
• HD/SD digital component signal
Output to the router IC (Used for outputting SDI/HDMI/VIDEO OUT (without characters))
• HD/SD analog component signal
Output through the A/D converter (IC805) to the router IC (Used for outputting SDI/HDMI/VIDEO OUT (with
characters))
• Analog composite signal
Output to the IO-255 board
• Video signal for LCD
Output through the KSW-62 board to the LCD
• Video signal for viewfinder
Output through the IF-1182 board to the DR-670 board
• Video signal for CODEC
Output through the router IC to the CODEC (IC500, 700: TORINO) on the DPR-343 board
• Return video signal
Input from the router IC
• Audio interface signal
Output to the AU-342 board
The peripheral circuit of the baseband processing IC T-ONE contains the following circuit and devices.
• Master clock 54 MHz VCXO (X1400) control circuit (including IC1401)
• Mobile DDR SDRAM (IC1100, IC1101)
• FLASH ROM (IC1201) and SDRAM (IC1200) as peripheral ICs of the internal CPU
1-3-4.

Media Recording/Playback System

DPR-343Board
Output signals from the baseband processor IC (IC900) on the DCP-56 board are transferred to the router IC ANDV
(IC1700) and the selector IC CAVS (IC100) on the DPR-343 board, and are then input to the MPEG encoder/decoder
TRINO (IC500, IC700) or the media block controller (IC1000).
The MPEG encoder/decoder (IC500, IC700) is a single-chip MPEG CODEC IC that encodes and decodes high-quality
HD image and audio signals in real time. It has various interfaces with MPEG video bitstream and baseband video input/
output, MPEG audio bitstream and baseband audio input/output.
The media block controller (IC1000) processes these signals and then files them, and writes the file data to the SxS
memory card through the SWC-54 board or the EC-75 board with the PCI Express interface.
This controller performs operation opposite to this procedure in the playback mode.
Furthermore, the media block controller (IC1000) has an internal CPU and a USB device controller for router IC CAVS
(IC100) control, serial communication with the system controller (IC2101), and data communication with each controller
through the PCI bus.
A flash ROM (IC1101) is also connected to IC1000, and the CPU program in IC1000 is read at the first startup.
Controlled by the system controller (IC2101) in the same way as other main devices, the DPR-343 board performs video/
audio stream control, SxS memory card access, mass storage operation through the USB connection, and HDV device
control through the i-LINK connection.
