1-2 AD951A & AD953A MPEG Test System Getting Started Manual

Product Description

'HYHORSPHQWDQG6\VWHP,QWHJUDWLRQ In the development environment, the MPEG
Test System is a convenient signal source and powerful debug tool. Its ability to
playout the same video test stream repeatedly, at data rates of up to 90 Mbps
provides the stimulus source for integrated receiver decoder (IRD) and modulator
developers.

The ability of the MPEG Test System to capture and analyze long video streams
allows engineers to rapidly search and identify video packets causing malfunctions
in the equipment under test. Stream capture can be triggered either by events in the
monitored video stream or by external sources.

The MPEG Test System can derive its playout clock from an external clock source,
or synthesize the correct clock setting for each file internally.

3URGXFWLRQ7HVW In the production environment, the MPEG Test System provides a
source of repeatable test patterns for the test and alignment of IRDs and
modulators. The reliability, embedded diagnostics, and modularity of the system
provide for the minimum down time during the working life of the unit.

7UDQVPLVVLRQ0RQLWRULQJ For program and service providers, the real time MPEG-
2 monitoring facility of the MPEG Test System provides confidence that the
program material meets the MPEG-2 requirements. Non-conformance to the
MPEG-2 rules is displayed on a graphical user interface, along with a statistical
analysis of the program multiplex.

All of the MPEG Test System facilities described above are available.

The MPEG Test System software applications require that a dongle be fitted so
that they can be accessed. A dongle is a small hardware device that is connected
directly to the parallel port. Any printer compatible with the installed operating
system can be connected to the unit through the dongle.

Each dongle is individually programmed for a user and enables the purchased set
of options. The dongle is installed at the factory.

The MPEG Test System is designed to operate from a single-phase power source
having one of its current carrying conductors at or near earth ground (the neutral
conductor). Power sources that have both current carrying conductors live with
respect to ground, such as phase-to-phase or multiphase systems, are not
recommended. A protective ground connection, by way of the grounding
conductor in the power cord, is essential for safe operation.

The electrical operating requirements for the AD951A & AD953A unit are shown
in Table 1-7. See the AD951A & AD953A MPEG Test System Technical Reference
for more detailed electrical characteristics.

DVALID Clock
Masking Enabled

This function only applies to the DVB parallel
input port.

Enabling this option allows the system to cope with packet sizes that are not
standard 188 or 204 byte. It does this by stopping the internal clock when the
DVALID signal is low.

In a 204 byte stream with dummy RS data, the DVALID signal will usually go low
on byte 189 and return to high on byte 1 of the next packet. In a 204-byte stream
with valid RS, the DVALID signal is always high and the clock masking function
will have no effect. Similarly, in a 188-byte stream the DVALID signal is always
high.

This function affects how the machine acquires sync and how it records. Before a
recording can start, five consecutive sync bytes have to be identified. Without the
DVALID function enabled, a check is made for the presence of a sync byte at the
188 and 204 packet boundaries and the state of the DVALID line is ignored. With
the DVALID function enabled, a check is still made for five consecutive sync
bytes every 188 or 204 bytes and the state of the DVALID line is checked, so that
counting only occurs in the periods when the DVALID signal is high since the
clock is masked when the signal is low.

Hence, in a stream where the DVALID is permanently high, acquisition will
depend on the packet sizes being correct. In a stream where the DVALID is low
between the end of a 188-byte packet and the next sync byte, any bytes in excess
of 188 will usually be ignored so that synchronization can be achieved with
packets of any size.

The DVALID Clock Masking Enabled tick box is only available when a file
selected for recording is a 188-byte file. When the DVALID function is enabled,
the generic record settings are for the packet type at the DVB interface and can by
default only be set to 188.

The General Purpose Serial Interface II+ (GPSI II+) is a ‘daughter board’ supplied
as an option to the MPEG Interface Card (MIC). This interface adapter card allows
connection to a broad range of ATSC and DVB equipment where a high-speed
serial interface is used. The range offered includes: RS422/485, ECL (AC), ECL
(DC), SMPTE 310M, DHEI and DVB SSI.

This ‘one card does all’ GPSI interface is able to internally recover or generate the
clock signal on bi-phase interfaces with on-board PLL and LSI logic. The GPSI
adapter has on-board high precision clock references that support ATSC 8-VSB
and 16-VSB bit rates. It also provides ECL support for the Harris CD-1, General
Instruments DHEI and negative ECL, and compatible equipment on the 26-way D­type connector.

The GPSI supports 188, 204 and 208-byte data packets.

The system provides software programmable input and output selection. The same
flexibility is extended to clock source selection for receive and transmit. The SSI
and SMPTE 310M can recover clock and data in the range 1 MHz to 44 MHz.

/D\RXW

Internally the GPSI adapter connects directly to the MIC card.

A simplified plan view of the GPSI II+ card is shown in Figure Figure B-1.

In some situations, such as when the power has been interrupted or files were
mistakenly deleted, the system may fail to boot from the hard drive. If this
happens, use the AD951A & AD953A MPEG Test System Recovery CD-ROM to
restore the hard drive to factory default installation status.

The AD951A & AD953A MPEG Test System contains one IDE hard disk drive
with one partition. The partition is approximately 4096 MB and is formatted with
the NTFS format.

To restore the contents of this partition (NT system and application software), use
the following steps. This restore process is effective only if the hard disk drive is
still good. (The process should take less than 15 minutes.)

1. Power up the MPEG Test System with the AD951A & AD953A MPEG Test

System Recovery CD-ROM in the CD-ROM drive.

2. Enter restdisk.bat at the DOS prompt.

3. Click Continue when prompted.

4. In the warning dialog box, confirm with Yes. A window will show the

progress of the restore function.

Networks are based on standards; however, there are many unique characteristics
of each network (LAN or WAN) that make it difficult to troubleshoot without a
thorough knowledge of the specific network. Consequently, an expert who knows
your network characteristics should perform in-depth network troubleshooting.

This appendix provides some basic procedures that can eliminate some of the more
common sources of network errors. If you cannot resolve problems using these
procedures, contact your network administrator.

%DVLF5HTXLUHPHQWV

Fulfill the following requirements before troubleshooting your host machines:

 Configure your system for use on the network as described in the

documentation that is supplied with the Network Adapter card. Contact your
network administrator for details.

,33DUDPHWHUV

 Ensure that any applications that you may have loaded on your test system

since receiving it are not using the ports assigned to the test system
components.

The illustrations in this section depict how each IP parameter (IP address, subnet
mask, and default gateway) can negatively affect network connectivity.

If the IP address for your test system is incorrect (not unique), then you may or
may not be able to communicate over the network. In Figure D-1, TVTest_1 uses
the same IP address as Rennes. If Rennes is started first, TVTest_1 will recognize
the IP address conflict and will not load TCP/IP; consequently, the system will not
be reachable over the network.

If your IP address is incorrect, and the IP address does not exist on your subnet,
you may be able to communicate from the device (system or monitoring station),
but you may not be able to communicate with the device.

Subnets and subnetting networks is complex and requires a thorough
understanding of IP addressing. Call your network administrator if you think your
networking problem involves subnets. Figure 4-8 shows a simple (and fairly
common) subnet mask problem.

In Figure D-2, the subnet mask for TVTest_1 indicates that the network address is
contained in the first two bytes of the IP address. In dotted decimal notation, the
network address is 128.181. This information allows the device to communicate
with any other device with the same network address without being routed through
a default gateway.

TVTest_1 cannot communicate with Carnac, because, according to the subnet
mask on TVTest_1, Carnac and TVTest_1 are logically on the same network.
Consequently, messages sent from TVTest_1 to Carnac are never routed. Because
these two devices do not share a medium, TVTest_1 will never find the correct
address for the network card on Carnac and will not be able to reach Carnac.

TVTest_1 can communicate with TVTest_2 and Rennes because these three
devices share a medium, so messages from TVTest_1 do not need to be routed.
TVTest_1 is therefore able to find the correct addresses for TVTest_2 and Rennes
in spite of having an incorrect subnet mask.

The default gateway you have specified in the TCP/IP Properties dialog box is the
device that “knows about” your subnetwork and others on your network. When
you send messages (for instance traps from your system to a device on another
subnet), the default gateway is able to route the message to the appropriate subnet.
If the IP address specified in the TCP/IP Properties dialog box is incorrect,
messages to devices on other subnets will not reach their destination (because they
never made it to the default gateway). See Figure D-3.

Many of the procedures performed in the following sections are common tasks.
Use these procedures when called for in the following sections.

3LQJLQJD+RVW0DFKLQH

One of the utilities provided with all TCP/IP installations is Ping.exe. (Look in the
C:\winnt\system32\ directory.) This utility allows you to send
communication packets to and record the response from an indicated host machine.
This, in essence, determines whether your packets arrived at the destination. To
run ping, use the following procedure:

1. Select Run from the Start menu. The Run dialog box appears.

2. Type one of the following into the Run text box:

ping machineName

ping IPaddress

In the examples, machineName and IPaddress represent the host
machine name and IP address, respectively, of the networked device you are
trying to ping.

3. Click OK.

A DOS window appears indicating whether or not the destination is
responding to the ping. In Figure D-4, the destination machine (Oxford4) is
not responding.

Ping only runs briefly, and the DOS window closes when the process is complete.

Sometimes it is helpful to know how far your packets made it on the way to a
destination machine and which devices the packets pass through on the way. The
utility that provides this functionality is tracert.exe. Tracert can also indicate
a congested point in the network. To run tracert, use the following procedure:

1. Select Run from the Start menu. The Run dialog box appears.

2. Type one of the following into the Run text box:

tracert machineName

tracert IPaddress

In the examples, machineName and IPaddress represent the host
machine name and IP address, respectively, of the networked device you are
trying to reach.

3. Click OK.

A DOS window appears (see Figure D-5) indicating the progress of your
packets. The far right column indicates the IP address of the nodes on the
network that successfully pass your tracert packets. This information
indicates the last good node on the path to the destination device.

At times, you may need to find or confirm the IP address of a computer on your
network (or, conversely, the network name if all you have is an IP address). You
may want to find this information to ensure that IP addresses and network names
you use in the Hosts file are correct. The utility that will display this information is
nslookup.exe. Use nslookup as described below:

1. Point to the Start button and then select MSDOS. The command line

interface appears.

2. Enter one of the following and press Enter, where machineName or IP

address is the network name or IP address, respectively, of the device you

are trying to lookup.

nslookup machineName

nslookup IP address

The network name and IP address of the device you are trying to lookup is
displayed. If your network uses DNS, the IP address and network name of
the DNS server is also displayed. See Figure D-6.
