Theory of Operation
This section describes the basic operation of the major circuit blocks or modules
in the MPEG generator. The Diagrams section, beginning on page 9-1, includes
a block diagram and an interconnect diagram. Figure 9-1 shows the modules and
functional blocks of the MPEG generator. Figure 9-2 shows how the modules
interconnect.
A10 Main Board
The A10 Main board consists of the following seven blocks.
Hard Disk Controller (SCSI
HDD X 2)
This block consists of two SCSI controllers, two 1 MB SRAMs, HDC_CPU
(SH-3) and the peripheral circuit, and a FIFO buffer to transfer data. Since the
SCSI controllers are connected to the Ultra Wide SCSI disks in single end, this
provides a maximum data transfer rate of 20 MW/s (40 MB/s) X 2. The data read
from the SCSI disks is transferred to the SRAM and then transferred to the
Change Packet block through the FIFO buffer. The SRAM can be accessed from
the PCI or HDC_CPU. When these disks are accessed, the HDD LED on the
front panel lights.
Change Packet
Change Word
Output Buffer
This block consists of the CP_CPU (SH-3) and peripheral circuit, FPGA, and
4 MB SRAM for data insertion. It executes packet operation. There are two
64X32-bit buffers in the FPGA and they can receive packets from the hard disk
controllers alternately. The content of the packets is examined by the CP_CPU,
and then the contents are changed. In addition, the 10 Hz pulse produced by the
27 MHz clock is input into the CP_CPU, it is used to insert the TDT or STT
packets.
This block consists of the CW_CPU (SH-3) and peripheral circuit, and FPGA. It
executes operation for the internal value of transport stream packets. There are
two 64X32-bit buffers in the FPGA, and they can receive packets from the hard
disk controllers alternately. The content of the packets is examined by the
CW_CPU, and then the contents are changed. In addition, the 10 Hz pulse
produced by the 27 MHz clock is input into the CW_CPU, which is used to
renew the time information of the TDT or STT.
This block forms a large FIFO buffer with the 1 MB SRAM and FPGA. It
converts the burst data to constant data and transfers it to the next circuit block.
It also multiplexes 32-bit/word data to 8-bit/word data. After data output is

Theory of Operation
started, the BUFFER LED on the front panel lights, unless the output buffer
empty.
Inserter
This block updates the PCR and PTS/DTS values, interfaces the peripheral
circuit of the output buffer/clock and the CPU module, and converts parallel
format data to SSI format data. For updating the PCR value, when the PCR
packet is detected, the value of the packet is added to the value of the 27 MHz
counter in the FPGA.
Output
This block outputs the control signals produced by the PLL section, such as
clock, the data signal from the inserter, PSYNC, and DVALID in single-end or
differential 50 W. These signals are converted to TTL, ECL, or LVDS levels.
This block also produces SSI and ASI signals based on DATA signals from
inserter, control signals, and the 27 MHz system reference signal, and outputs
them at 75 W. These output signals can be High Z under control of the CPU.
Clock
This block generates four types of clock signals and supplies them to the A10
Main board: 27 MHz clock signal as a system reference, 1–64 MHz clock
signal, [(1–64) * 2] MHz clock signal, and [(1–64) / 8] MHz clock signal. To
generate these four types of clock signals, this block has three operation modes:
Internal Reference mode, External Reference mode and External Clock mode.
When the External Reference or External Clock mode is selected from the menu,
the EXT LED on the front panel lights. The PLL LED also lights when the PLL
is locked.
CPU Unit
The CPU Unit consists of the CPU board, A20 Interface board, LAN board, and
backplane.
Backplane
CPU Board
The backplane has five PCI bus slots. This board receives power from the A40
MISC (Power Distribution & Interface) board and routes it to each board.
The first and second slots of the Backplane contain the CPU board, which is
based on an Intel Pentium processor and runs Vx Works. The CPU board
controls the user interface, display, each hardware block, and the downloading
and uploading of data through the Ethernet interface. This board also has a flash
disk, a 3.5 inch floppy disk drive, and a IDE hard disk drive as peripheral
devices.
A20 PCI Interface Board
The third slot of the Backplane has the PCI Interface board that consists of the
PCI interface chip and its peripheral circuit, and an FPGA that works as an

Theory of Operation
address decoder. The PCI Interface board provides the communication between
the CPU module and A10 board and A40 board.
LAN Board
The fourth slot of the Backplane contains the Ethernet LAN interface board. The
MPEG generator has a 100 BASE-T/10 BASE-T connector on the rear panel.
A30 Front Panel Board
The A30 Front Panel board consists of the CPU to create key codes, rubber
contact switches, rotary encoder, and four LEDs. The key codes are transferred to
the CPU unit with the keyboard control CPU through the RS-232C interface.
A35 Power Switch
The power switch is a push-type switch with ground closure. It is connected to
the A40 MISC (Power Distribution & Interface) board through the A30 Front
Panel board.
A40 MISC (Power Distribution & Interface) Board
The A40 MISC (Power Distribution & Interface) board distributes the +3.3 V
and –5 V power supply voltage derived from the +5 V and + 12V power
supplied from the Power Supply. It supplies them to the each board and module,
fans, and hard disk drives. It also provides interface between the LCD module,
floppy disk drive, A30 Front Panel board and the CPU unit.
A50 SCSI Termination Boards
The SCSI bus termination for the Data HDDs consists of the two termination
regulators and termination resistors.
Power Supply
The Power Supply derives the +5V and +12 V power supply voltages from the
AC line and supplies them to the A40 MISC (Power Distribution & Interface)
board.

Maintenance
Inspection and Cleaning
Inspection and Cleaning describes how to inspect for dirt and damage. It also
describes how to clean the exterior and interior of the MPEG generator.
Inspection and cleaning are done as preventive maintenance. Preventive
maintenance, when done regularly, may prevent MPEG generator malfunction
and enhance its reliability.
Preventive maintenance consists of visually inspecting and cleaning the MPEG
generator and using general care when operating it.
How often preventative maintenance should be performed depends on the
severity of the environment in which the MPEG generator is used. A proper time
to perform preventive maintenance is just before MPEG generator adjustment.
General Care
The cabinet helps keep dust out of the MPEG generator and should normally be
in place when operating the MPEG generator. The MPEG generator’s front cover
protects the front panel and display from dust and damage. Install it when storing
or transporting the MPEG generator.
Inspection and Cleaning
Procedures
Inspect and clean the MPEG generator as often as operating conditions require.
The collection of dirt on components inside can cause them to overheat and
breakdown. (Dirt acts like an insulating blanket, preventing efficient heat
dissipation.) Dirt also provides an electrical conduction path that could cause an
MPEG generator failure, especially under high-humidity conditions.
CAUTION. Avoid the use of chemical cleaning agents that might damage the
plastics used in this MPEG generator. Use only deionized water when cleaning
the menu buttons or front-panel buttons. Use a 75% ethyl alcohol solution as a
cleaner and rinse with deionized water.
Inspection Ċ Exterior. Inspect the outside of the MPEG generator for damage,
wear, and missing parts, using Table 6-2 as a guide. MPEG generators that
appear to have been dropped or otherwise abused should be checked thoroughly
to verify correct operation and performance. Immediately repair defects that
could cause personal injury or lead to further damage to the MPEG generator.
