• 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-343 Board
Output signals from the baseband processor IC (IC900) on the DCP-61 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 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.
Peripheral Devices
SxS memory card slot
The 2-channel PCI-Express signal from the media block controller (IC1000) is input to the two memory card slot boards
(SWC-54, EC-75) through the 0.4 mm-pitch 30-pin fine-wire coaxial cables connected to CN1400 and CN1401.
The 2-channel USB host signal that is output from the media block controller (IC1000) by controlling USB host controller
(IC1301) is sent to the SWC-54 and EC-75 boards through fine-wire coaxial cables in the same way as the PCI-Express
signal. IC1301 is controlled by IC1000 through the PCI bus.
USB device controller
USB device signals input/output from the USB device controller in the media block controller (IC1000) are input to the
USB Mini-B connector (CN2200).
USB host controller
The USB host controller (IC1301) takes charge of one channel for connection to Wi-Fi adapter or USB memory in
addition to two channel of slots for SxS memory card.
The USB host signal input/output from the USB host controller (IC1301) is transferred from CN2501 through the
shielded harness to the IO-254 board, and is then transferred to the USB TYPE-A connector (CN101).
IC1301 is controlled by IC1000 through the PCI bus.
