connecting the MPEG generator to a power source.  
WARNING. AC POWER SOURCE AND CONNECTION. The MPEG generator  
operates from a single-phase power source. It has a three-wire power cord and  
two-pole, three-terminal grounding type plug. The voltage to ground (earth) from  
either pole of the power source must not exceed the maximum rated operating  
voltage, 250 volts.  
Before making connection to the power source, be sure the MPEG generator has  
a suitable two-pole, three-terminal grounding-type plug.  
GROUNDING. This instrument is safety Class 1 equipment (IEC designation).  
All accessible conductive parts are directly connected through the grounding  
conductor of the power cord to the grounded (earthing) contact of the power  
plug.  
WARNING. The power input plug must be inserted only in a mating receptacle  
with a grounding contact where earth ground has been verified by a qualified  
service person. Do not defeat the grounding connection. Any interruption of the  
grounding connection can create an electric shock hazard.  
For electric shock protection, the grounding connection must be made before  
making connection to the instruments input or output terminals.

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  
3Ć2

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  
Preparation  
Before servicing this product, read the Safety Summary and Introduction at the  
front of the manual and the ESD information below.  
CAUTION. Static discharge can damage any semiconductor component in the  
MPEG generator.  
Preventing ESD  
When performing any service which requires internal access to the MPEG  
generator, adhere to the following precautions to avoid damaging internal  
modules and their components due to electrostatic discharge (ESD).  
1. Minimize handling of static-sensitive modules.  
2. Transport and store static-sensitive modules in their static protected  
containers or on a metal rail. Label any package that contains static-sensitive  
modules.  
3. Discharge the static voltage from your body by wearing a grounded antistatic  
wrist strap while handling these modules. Do service of static-sensitive  
modules only at a static-free work station.  
4. Nothing capable of generating or holding a static charge should be allowed  
on the work station surface.  
5. Handle circuit boards by the edges when possible.  
6. Do not slide the modules over any surface.  
7. Avoid handling modules in areas that have a floor or work-surface covering  
capable of generating a static charge.

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.
