DVB+ Satellite Receiver: Overview

The Mainstream Data DVB+ Receiver, shown in Figure 1, tunes and demodulates a Digital
Video Broadcast-S, L-band RF signal input to provide data output. The DVB+ extracts IP
multicast packets from MPE sections and passes them out the Ethernet port based on the
authorized Program Identification Descriptions (PIDs) and multicast addresses. In addition, the
DVB+ can pass asynchronous output data through a standard serial port.

Note: Throughout this guide, the DVB+ Satellite Receiver is referred to simply as the “DVB+” or “the

receiver.”

Figure 1 The DVB+ Satellite Receiver

Features of the DVB+ Satellite Receiver

Features of the DVB+ include the following:

• DVB-S compatibility

• 40 Mbps of sustained throughput

• 32 PID and 32 multicast address filtering

• Traditional Mainstream Data IDR support over DVB channels

• Configurable via front panel buttons and LCD, Web interface, or over-the-air network

download

MS4966 Rev 1.2 1

Safety Issues and Precautions

Protect yourself and help keep the DVB+ operating without disruption by following basic,
common sense procedures.

Do:

• Unplug power before changing external cables. This reduces the chance of electrical shorts

that could damage the receiver.

• Protect the DVB+ from liquids and excessive heat, humidity, or dust. These elements can

damage the processor electrical components.

• Connect the DVB+ only to grounded power outlets.

Do Not:

• Open the casework. Nothing inside the DVB+ is field-repairable. (Opening the case voids

the Mainstream Data equipment warranty.)

• Stack the receivers. Vents in the DVB+ casework are designed to provide the necessary

ventilation to the components. While the footpads on the receiver may help provide
sufficient space for ventilation, stacking is not recommended.

Documentation and Customer Support

This guide provides the high level information needed to understand the DVB+ Receiver in its
operational context. Site- or customer-specific information is not provided here. Typically a
Mainstream Data customer service representative or a network operator supplies the detailed
settings, procedures, and contact number for specific sites.

2 MS4966 Rev 12

Installing the DVB+ Satellite Receiver

This section summarizes the steps involved in setting up the DVB+ Satellite Receiver. After
cables are connected, you will need to verify or establish DVB+ settings through the front
panel LCD. This information is covered in the next section, “Understanding DVB+ Settings”

Note: If you do not yet know the expected Eb/N0 reading and AGC levels for the site, contact the network

operator now.

Caution: Rain, snow, high winds, or extreme cloudiness can attenuate the signal. Try to avoid installing the

receiver during inclement weather, if possible, to minimize installation difficulties.

Before You Install the DVB+

Verify the following conditions:

1. A suitable satellite dish (with proper grounding) is already installed.

2. Coaxial cable is already run from the dish to the receiver location. (RG-6 cable is

recommended, length not to exceed 300 feet.)

3. RF coaxial cable shield is connected to earth ground with a #10 gauge (or heavier) solid

copper wire at the point of entry to the building.

4. RS-232 serial cable is shielded, with shield wire attached to connector shell at both ends

of the cable. Cable is “straight-through” (not NULL modem) if attaching directly to a PC
COM port.

5. Ethernet cables are of CAT-5 quality.

6. Power module is not yet connected to the DVB+.

Caution: : To prevent accidental shorts from causing circuit damage, the power module should always be

disconnected during installation or whenever cables are being changed.

MS4966 Rev 1.2 3

Step-by-Step Procedures

Installing and verifying DVB+ operation requires use of the LCD front panel. If you have not
previously installed Mainstream Data receivers or are unfamiliar with using the front panel, refer
to the next section, Understanding DVB Settings for the appropriate information on using the
panel.

Step 1: Connect the cables

1. Connect the coaxial cable to the RF Input connector.

2. Connect a RS-232 asynchronous cable to the Serial port to view traditional IDR-type

receiver data. (This port operates similarly to previous Mainstream Data IDR models.)

3. Connect an RJ-45 Cat-5 Ethernet cable to the DVB Channel port. This is the high-

speed connection delivering multicast content.

Note: If you are connecting directly to a PC instead of to a network hub, use the supplied cross-over

cable.

4. Connect an RJ-45 Cat-5 Ethernet cable to the Aux Channel port and to a PC if you
want to view or configure the DVB+ using a Web browser, such as Internet Explorer.

Note: If you are connecting directly to a PC, use the supplied cross-over cable.

5. Connect the power module to the DVB+ power input and to the power source.

On power-up, first the Power LED lights, then the remaining LEDs light and all flash once,
then the Power LED alone remains lit; simultaneously, a right and left LED in both the Aux
Channel and DVB Channel ports flash once. At power-up the port LEDs flash once: the left
LED means Link is UP; the right LED means Speed = 100Mbps.

When the DVB+ is booting, and during operation, the meaning of the right LED on each port
changes to indicate transfer (TX) activity.

Power

This equipment complies with the requirements in
Part 15 of the FCC rules for a Class A computing
device. Operation of this equipment in a residential
area may cause unacceptable interference to radio or
television reception, requiring the o p erator to take
whatever steps are necessary to correct the s ituation.

RF Input

4 MS4966 Rev 1.2

Step 2: Verify Initial Lock on Carrier

As soon as power is applied to the DVB+, an automatic self-test runs. The DVB+ then
attempts to locate and lock onto the preset carrier.

If a DVB carrier is not found the DVB+ toggles back and forth between the primary and the
alternate carrier until a lock is obtained on one of the channels. The receiver stores the last
known “good” channel carrier, and a subsequent reboot first tries to achieve lock on that
channel. If no alternate carrier has been specified in the receiver setup, the receiver attempts to
lock to the primary carrier until lock is achieved or the box is powered off.

To verify the receiver is locked to the preferred carrier, check the blue Lock LED on the front
panel and also the Show Status>Show Tuner Status LCD screens. Figure 3 shows the screen
location of the applicable status settings.

MS4966 Rev 1.2 5

Step 3: Verify Signal Strength

Signal strength quality is indicated mainly by the Eb/N0 reading in the Show Tuner Status
screen. It is possible to fine tune that reading by slightly adjusting the position of the satellite
dish. The Eb/N0 should be at least 5.0, usually higher, depending on environmental conditions.
(Your site will have specific requirements.)

The AGC level indicates the signal strength at the input of the tuner and can be used to verify
that the cabling is complete and the LNB is getting power from the DVB+. The reading should
be within a range of 800 to 1020, with 1000 being typical. If the number is under 800, check the
coaxial cable connections and the LNB on the satellite dish.

Step 4: Call Customer Service for Network Download

If your DVB+ is designated for a network download, your customer service representative can
arrange for the Network Operations Center to download the appropriate configuration for your
site.

Once the Eb/N

and AGC readings are at the expected levels and the Eb/N

0

has been

0

maximized by adjusting the dish alignment, notify your customer service representative.
Your customer service representative may provide you with additional instructions following

the download.

Note: If the DVB+ was pre-configured at the factory, the necessary settings may already be established and do

not need to be downloaded. Verify this with your site coordinator.

6 MS4966 Rev 1.2

Step 5: Verify Data Output

If you are using the Serial port, you can verify its data output by performing various test
functions:

1. Request a test transfer from the NOC.

2. Connect the RS-232 cable to a computer and run Windows HyperTerminal to check
receiver settings.

3. Load a feed from a data provider to the test computer, and receive the file in
HyperTerminal.

To verify data output from the Aux and DVB Channels after cables are connected:

1. Check the link lights on the ports. The left indicator shows that the link is up, meaning
the Ethernet cable has properly connected; the right indicator shows transfer activity.

2. Check the Aux Channel port by setting up a connection between the receiver and a PC.
Set up a Web browser on the Aux Channel (see Using the Web Browser Interface) and
browse the DVB+ home page. (You need the IP addresses for both the receiver and the
PC to do this. Refer to the DVB+ View Aux LAN Setup LCD screen to view the IP
address of the receiver.) If necessary, “ping” the receiver to check that cable connection
is good.

3. Run a valid data feed through the DVB Channel Ethernet port while monitoring with a
suitable client PC application.

Corrective Actions and Status Monitoring

If data output through any of the channels is not as expected, first recheck the Eb/N

and AGC

0

readings and then perform alignment corrections as needed.
Refer to the next section for descriptions of various status and setup LCD screens that provide

useful information: the Show Status>Show IDR Status screen, shows the critical statistics for
stat mux operation. The Show Status>Show IP Channel Status screens show the critical
statistics for multicast operation.

Step 6: Maintain the Equipment

Satellite transmission can be adversely affected by bad weather. High winds can knock a satellite
dish out of alignment, and heavy snows, rain, or cloud cover can severely diminish signal
quality. You, or another designated individual at your site, should attend to the following
maintenance activities:

• Check satellite dish alignment by monitoring the E

• Remove snow from the satellite dish using a stiff whiskbroom.

• Make sure snow doesn’t accumulate on the dish and that the feedhorn window is clear.

Understanding DVB+ Settings

All DVB+ receivers are pre-configured with a unique Ethernet MAC address and unique
Mainstream Data identification number, at a minimum. In addition, depending on specific
network or customer requirements, various features or services (other than the MAC address
and MSD ID) can be adjusted when the receiver is installed.

These factory settings can be changed after installation, in three ways or combinations thereof:

• Front panel with LCD display and pushbuttons

• Web browser interface

• Network download, using the optional NMS (a network-dependent option)

The DVB+ front panel is designed similarly to previous Mainstream Data receiver models;
current receiver users will be familiar with the 2-line display and tree structure of the menu
options. The front panel LCD and keypads are necessary at installation to set and achieve a lock
on the RF signal. Once the DVB+ is set up, subsequent configuration changes can be
downloaded from the Network Operations Center or entered through the Web browser
interface, as well as through the front panel.

Current settings can be viewed on the front panel or through the Web interface.
This section discusses how to use the front panel and the Web interface and how to interpret

the screens that are displayed.

Using the Front Panel

You can view and modify configuration settings, as well as view dynamic performance of the
DVB+ from the front panel LCD. Once you become familiar with the usage of the buttons,
this 20-character-by-2-line display provides a direct and intuitive interface to the DVB+
functions.

Front Panel Indicators

When power is first applied, the four indicators --- Power, Lock, Active, and Data--- flash
twice. The Power indicator stays lit while the DVB+ is booting. If signal lock has been
achieved, the Lock indicator stays lit.

The Active indicator is triggered when any valid packet is received from any PID. The Data
indicator lights when stat mux data is actually output through the Serial port or when DVB data
is output through the Ethernet port (Basically, the Active indicator shows that the DVB+ and
its satellite feed are functioning; the Data indicator shows that you are receiving usable data.)

LCD Screen

The Mainstream Data identification screen displayed after the receiver finishes its initial startup
procedure is the “home page” of the front panel. Pressing the SELECT button moves the
display to the first of four main stems of the menu “tree.” The four main stems are:

Entering and Changing Values

Some screens are designed for entering new values or for modifying existing values.

• Use the arrow buttons to increment or decrement the value displayed above the cursor.

• Press SELECT to advance the cursor to the right.

• Press CANCEL to move the cursor to the left.

Once the cursor is moved to the rightmost position, press SELECT again to store the value.
Invalid entries are not accepted by the DVB+. For example, if you try to enter the first byte of

an IP address as 257 (where the maximum allowable value is 255), the entry is rejected.

Overview of LCD Displays

Some LCD screens are static, meaning the screen is painted once upon entry and does not
change thereafter. However, some screens are dynamic, allowing variables, such as AGC, to be
observed in real time.

Note: Dynamic screens consume processor time, which reduces the available capacity for data processing.

Although the same current settings are displayed within the Specify Setup subordinate screens,
it is preferable to view the receiver setups only from the View Setup screens. An inadvertent
keystroke within Specify Setup could modify an important setting. Even more problematical,
features listed under Utilities usually place the receiver into a special mode, many of which can
disable data output.

Caution: Changes made within the

Specify Setup

and

Utilities

screens can disrupt system output.

Using the Web Browser Interface

Most DVB+ configuration parameters can be viewed or changed from the Web page interface.
Although the menu structures of the front panel and Web interfaces are not identical, any
changes made to a variable through the Web interface are immediately visible on the LCD
panel, and vice versa.

Figure 22 Home Page of the DVB+ Web Interface

The receiver includes a Web server application that is accessed by setting up Windows to point
to the IP address of the DVB+ Aux Channel. As you click on a menu box to open a new page,
a snapshot is taken of the DVB+ variables associated with that screen image. These variables
are presented as a static display on the browser screen. To see if a counter is incrementing or to
observe new settings, you can refresh the page by re-clicking the blue page menu button.

Entering and Updating Values on the W eb Pages

New values that are entered on a Web page are submitted to the receiver by clicking the
SUBMIT button at the bottom of the page (or on some browsers by pressing ENTER on the
keyboard). If any submitted values are not valid a red error message appears at the bottom of
the page when that page is repainted. No updates are made to any variable on that page if you
have entered an erroneous value in any of the fields. For some fields, red error messages of
submitted invalid entries are displayed in the upper right corner of the screen.

PID Filtering and DVB Decryption Page

In the Filtering page, you can view, add, or delete PIDs and IP multicast addresses that are
filtered for reception.

Figure 23 PID Filtering and DVB Decryption Web Page

You can enter PID values using either hex or decimal values. ( Both hex and decimal values
can also be seen within the View Setups LCD screen.) Enter encryption keys as 16-character
values. The Conformance bit entry is a “yes” or “no”.

Note: To specify no encryption exists leave the Key and Conform fields blanks. For example, if an existing

PID contains keys that you want to delete, “add” the same PID number, leave the Key and Conform
fields blank, and click on Submit.

The same process can be accomplished through the Specify Setups>IP Channel

IP Filters

In the IP Filters page you can add or delete multicast addresses selected for filtering and
determine for each whether MSD decryption should be applied.

If you are adding an address, enter it in the first box adjacent to add Mcast. In the next box,

Ethernet Port Configuration Screen

If you change any of the Aux port Network Parameters, such as the receiver IP address, you
need to reboot the DVB+ for those changes to take effect. If you need to make several changes
to these Network Parameters it is more expedient to make all the changes first, and then reboot
once.

IP remapping, sometimes called Network Address Translation (NAT), is useful in situations
where existing applications running on the local LAN are already using a specific IP address.
You can remap an IP address on the DVB+ to prevent addressing conflicts.

are not being checked in that mode.

The Ethernet counter reflects output activity on the DVB+ 100baseT connector. It can
increment even when the IP filter hit counter does not increment.

The DVB+ tunes to the L-band frequency. The carrier frequency and the LNB oscillator
frequency fields are provided mainly for the installer’s convenience who is aware of the
applicable equation: L-Band frequency = carrier frequency – LNB oscillator frequency.

This page enables you to either force the given L-Band tuner frequency based on the entry in
the L-Band frequency field or to require the receiver to compute the L-Band frequency based
on the entry in the Carrier frequency field. This flexibility may be useful depending on the type
of information provided at installation time.

Demodulator Web Page

The Demodulator page is a read-only status page of current signal information, including lock
status, signal quality, and error counters. The page is automatically refreshed every 4-5 seconds.

Event Log Web Page

The event log timestamps occurrences of designated system activities and functions. As a
diagnostic tool the event log is useful for verifying that signal quality has dropped below (or
increased above) a threshold, that the demodulator has unlocked (or relocked), that downloads
have occurred, that various settings have been changed locally, or that various system faults
have been detected..

Figure 30 Event Log Web Page

The event log functions differently depending on DVB+ release level. In early releases the
event log stores up to 100 events in RAM; the list is lost during power cycling or rebooting. In
later releases, the event log is stored in non-volatile memory. That list is maintained throughout
subsequent reboots or power cycling.

To change logged events, check or uncheck the category boxes, then click on the Change
Flags button. To erase old events and restart the log, click on the Restart Event Log button.

Functional Overview

This section contains background information on data flow through the network and on the
functionality of the DVB+ Satellite Receiver.

Network Overview

The DVB+ Satellite Receiver provides data out by extracting IP multicast packets from MPE
sections and passing them out the Ethernet port labeled on the receiver as DVB Channel. The
unit extracts IP multicast packets from MPE sections based on the specified Program
Identification Descriptions (PIDs) and multicast addresses. In addition, the DVB+ can pass
output data through a standard serial port.

Network Components

The network comprises the following main areas:

• Access Network

The access network includes various means by which data arrives at the NOC from remote
sites over wide area networks, as well as through local PCs.

• Network Operations Center (NOC)

The NOC gathers and processes incoming data, uplinks data directly to a satellite or
transmits data to another site for uplinking, and provides network management services.

• Satellite

Channel space is leased on satellites by your network provider.

• DVB+

The DVB+ receives and processes the incoming data from the satellite downlink. It passes
the data to its attached output devices, such as local servers, an auxiliary monitoring PC, or a
LAN hub.

The Network Operations Center: Input and Output

Input to the NOC consists of data feeds arriving through the access network from remote or
local computers. Some of this data is processed through a statistical multiplexer (stat mux), and
some is sent unmodified as multicast packets. The multicast streams sent over satellite typically
include high-speed data streams in proprietary formats generated by the data originator.

The stat mux data is assembled into a series of packets. The packets contain information about
the data, such as message length, source, specific output destination, encryption or compression
keys, as well as the data itself.

The stat mux data, control channel information, and other data passing directly from the access
network is aggregated into a single DVB data stream and converted to a digital signal. This
signal is either directly modulated and uplinked to a satellite from the NOC or is transmitted to
another site for modulating and uplinking.

MS4966 Rev 1.2 43

The DVB+ Satellite Receiver

The DVB+ receives data input from the satellite dish. The downlinked data stream is amplified
and shifted to a lower frequency by the LNB on the dish and passed through the coaxial cable
to the DVB+. The receiver demodulates the data and applies error-correction. Data is then
routed to the FPGA (Field Programmable Gate Array) for further processing. The FPGA
reconstitutes the original multicast packets. For data for which no further processing is
required, the data is routed directly from the FPGA to the DVB Channel Ethernet port. The
stat mux data is routed to the processor in the DVB+ for additional processing.

The processor handles the statistical demultiplexer channel, which includes a control channel.
The control channel is created by the Network Operations Center. The control channel is used
to send configuration information to the receiver. This configuration information specifies
which PIDs and multicast addresses the receiver is allowed to receive, which pools and groups
are allowed on the stat mux channel, and other parameters. Additionally, the stat mux channel
may contain data which is destined for the serial port on the receiver. The primary use of the
serial port data is to support legacy applications which have used a Mainstream Data IDR.

Figure 33 Functional Overview of DVB+

An L-Band satellite tuner subsystem in the DVB+ accepts signals from a roof-mounted dish
and low noise block converter (LNB) via a coax cable. The DVB+ provides power through the
coax for this LNB, as well as any in-line amplifiers. One of two voltages, 14 volts or 18 volts
can be sent up the coax cable. This allows for LNBs that use incoming voltage to switch
polarity, usually “high band / low-band”, though many LNBs have no such feature and will
work equally well on 14 or 18 volts. The LNB voltage can have a 22 kHz tone (0.5 v p-p) added
to the DC voltage for use with LNBs that switch oscillator frequency based on the presence of
the additional tone. The LNB voltage can also be turned off. LNB voltage and tone settings can
be selected via the LCD/keypad interface, or Web page interface, and by download. The LNB
power supply is immune from “back-power” (a higher voltage present on the LNB coax than is
being generated internally).

MS4966 Rev 1.2 45

It is common for a satellite service to have a backup carrier that will be used in the event the
primary carrier fails. The DVB+ has the means to store two settings for carrier parameters
(MAIN and ALT), and if configured properly, checks for a valid carrier at the alternate
frequency if the primary carrier becomes unavailable. A specific RF channel is defined by six
parameters:

• L-Band frequency

• Baud rate

• Modulation type

• Control Channel PID

• LNB voltage

• 22kHz tone

Thus a backup (ALT) carrier need not be the same baud rate, or even the same polarity, as the
primary carrier. If no alternate carrier is available its settings can be disabled. If both RF
channels are enabled the receiver will check both, toggling back and forth, until a lock is
obtained. That channel is then marked as the “known good” channel. All subsequent reboots
will cause the receiver to check the “known good” channel first, at least until the receiver is
forced into hunting for a valid carrier again.

The tuner can acquire satellite signals that are slightly off frequency thus accommodating LNBs
with DRO-type oscillators. The acquisition range of the tuner has been set for +/- 2 MHz.
Once locked, the tuner can track carrier frequency variations up to +/- 2 MHz from the desired
frequency. When locked the carrier frequency can be displayed on the LCD display or
Demodulator Web page.

Once locked the demodulator chip provides an estimate of the carrier Eb/No. This is displayed
on the LCD display and Tuner Web page. This field is the most sensitive indication of optimum
dish alignment and is preferred to the AGC because the AGC value will stay constant over a
wide range of LNB polarization settings, while the Eb/No will change dramatically for any
small changes in polarization, dish azimuth, or elevation. Eb/No values below 5 will usually
indicate the link performance will be poor as small disturbances to the signal will cause the
Eb/No to drop below the threshold required for error-free performance.

FPGA: Processing Sequence

Figure 33 includes a block representing the Field Programmable Gate Array processing.
MPEG2 frames from the Tuner/Demodulator subassembly are passed to the FPGA where the
following sequence (a pipeline) of operations is performed:

Bad frame filter

MPEG frames that are uncorrectable by the Reed-Solomon error corrector are discarded.

PID filtering

The PID value of each incoming frame is checked against each of the 32 possible entries in the
PID filter table. If there is a match with any entry in the table, the frame is kept; otherwise, the
frame is discarded. In a typical installation dozens of PID streams may be present on a DVB
carrier but only a few are desired by the user.

46 MS4966 Rev 1.2

DVB Decryption

Each PID stream can be decrypted by the DVB decryption process. Feeds that are not DVB
encrypted are unaffected by the DVB decryptor. Decryption requires the proper key values and
proper setting of the conformance bit, each of which can be downloaded or entered from the
Web page or LCD display, unless such access has been denied by the operator.

Section Depacker: Each PID stream on a DVB carrier may contain a different type of

data including video, audio, or non-IP data feeds. Such feeds cannot be decoded by the DVB+
and are discarded. PIDs that conform to the MPE Section format and contain IP packets are
kept and decoded. The DVB+ can decode PID feeds that are Section-packed or non-Section­packed, or any combination thereof.

IP datagram extraction

Each valid MPE section is parsed to extract the IP packet that it contains. If the IP packet is
valid and contains a UDP or multicast payload, it is kept and passed to the IP address filter,
otherwise discarded.

IP filtering

The destination IP address of each valid IP packet is checked against each of the 32 possible IP
address table entries. If there is match with any of the table entries the packet is kept; otherwise,
it is discarded. The source IP address is not checked. A single PID may contain multiple IP
address streams.

MSD IP decryption

Surviving IP packets may need to have IP-layer MSD encryption removed. Each IP address
table entry can have MSD IP decryption turned on or off.

High Speed Group Codes

IP packets are next subjected to the High Speed Group Code filter. If the destination IP
address in the packet matches the IP address setting in the filter, the packet is assumed to
contain additional group code information that was inserted before being transmitted. If no
match exists, the packet is passed forward untouched. If group codes are present, the 32 byte
group code mask in the packet is checked against the 32 byte mask in the filter. A match at any
bit position will cause the packet to be accepted, others discarded. Accepted packets are
reformatted to remove the 32 byte group code mask thereby returning it to its original format.
This type of filtering is not possible with IP addressing alone, as each message can be tagged
with multiple group codes.

IP address remapping

The destination IP address of each packet is checked against each of the four destination
addresses in the remapping table. If any match is found the destination address in the packet is
replaced with the new destination address found in the table. If no match is found the packet is
passed forward untouched. This is useful when the IP multicast address of a satellite data feed
conflicts with an IP multicast address service already being used in that LAN environment.

MS4966 Rev 1.2 47

Ethernet frame generation

IP packets are turned into Ethernet frames by encapsulating the IP packet with 802.3 Ethernet
frame information fields including a source MAC address (which is the address of the DVB
port of the DVB+ receiver), a destination MAC address which is derived from the IP
destination address as per the IP Multicast standards, and a valid checksum. Frames are then
queued for output to the DVB Ethernet port. A buffer in the FPGA allows for several Ethernet
frames to be held while the Ethernet wire is being used by other senders.

Error Correction

The Viterbi decoder is auto-configuring; thus it is not necessary for the user to select a desired
code rate. The code rate that is discovered during carrier acquisition is reported on the LCD
display and Tuner Web page.

The Reed-Solomon FEC function can remove errors which are left behind by the Viterbi
decoder. Each Reed-Solomon block can correct a certain number of bad bytes within an
MPEG frame (there is one Reed-Solomon FEC block in each MPEG frame). When the
number of bad bytes exceeds the capability of the Reed-Solomon code the algorithm fails to
correct any of them and passes the corrupted block forward, but flagged to indicate that it
contains an unknown number of damaged bytes. Counts are kept of the number of bits that
have been corrected, as well as the number of uncorrectable blocks. These counters are
available on the LCD display and on the Demodulator status Web page. Another LCD field,
CBitRate, displays a real time calculation of the number of bits corrected by Reed-Solomon
divided by the total number of bits received (since the counters were cleared). This equals the
pre-Reed-Solomon bit error rate (assuming there are no uncorrectable blocks during the test),
which is useful for demodulator performance measurements.

Status Monitoring

The DVB+ includes three mechanisms for reporting and viewing various types of receiver and
activity status. The Stat Logger LCD screen, under the Utilities menu, is used to send a line
of status information through the RS-232 serial port. This information can be viewed through a
PC running the Hyperterminal program.

The Status Packet LCD screen, also within the Utilities menu, outputs signal strength,
Eb/No, demodulator error counts, MPE section error counts, and carrier lock/unlock data as
UDP packets in XML format.

The third status monitoring mechanism is through the Web page interface. Signal fluctuations,
carrier lock/unlock data, downloads, local configuration changes, and system faults are captured
and timestamped within the page.
