Congratulations on purchasing the Intraplex HD Link radio frequency (RF) studio-to-transmitter link (STL)! This document

provides initial system setup instructions. The installation and operation manual gives more detail on system operation. To

download the most current version of the manual, go to

http://www.broadcast.harris.com/support/.

A) Install Transmitter & Receiver

Install each unit into a 19" equipment rack. If either the HD

Link transmitter or HD Link receiver is to be stacked in a rack

with other shelves, allow at least 1RU space between shelves

to avoid possible heat problems.

Note: Make sure the power cable can be accessed easily for

maintenance purposes.

B) Set Up Wiring

Before using the HD Link transmitter and receiver, you need

these connections already set up:

Transmitter

● Antenna: A threaded N type connector using low-loss

cable and leading to a transmitting antenna intended for

use in the 950 MHz band

● Audio input connections (Analog L+R or AES) from the

primary program source

● AC power cord

Receiver

● Antenna: A threaded N type connector using low-loss

cable, possibly leading to a cavity filter, and leading to a

receiving antenna intended for use in the 950 MHz band

● Audio output connections (Analog L+R or AES) to your

external equipment

● AC power cord

Section 3 – “Installation” of the installation & operation

manual contains detailed HD Link connection information.

C) Power Up

Warning! Plug in all transmitter or receiver connections

before applying power.

Connect the AC power cord to a live power source and wait

while the system initiates. All three front panel lights are on

until the initial display screen appears.

Note: When the system first comes on, the fans run at full

speed temporarily and then regulate to normal

operating speed.

D) Configure HD Port

If you need to transport Ethernet traffic, you must set up the

networking parameters. Otherwise, you can skip this section.

1. On the HD Link Main page (Figure 1), select System

Setup and press Enter to access the menu (Figure 2).

Figure 1. Main Screen

Figure 2. System Setup

2. On the System Setup page, select Network Setup and

press Enter to access the menu (Figure 3).

Figure 3. Network Setup

3. On the Network Setup page, press Enter with HD Port

selected to access the HD Port screen (Figure 3).

5. Configure RF Profile parameters in a similar way to the

HD Port parameters in Section D, Step 3.

Note: Set the RF bandwidth according to your FCC license.

When you set other service parameters, the bandwidth

does not change.

G) Configure Service Profile Parameters

Note: Be sure to configure your transmitter and receiver

identically.

To configure the audio port and user IP rate parameters,

perform these steps:

1. On the Service Setup menu, select Service Profile and

press Enter to access the screen (Figure 8).

Figure 8. Service Profile

2. Configure each Service Profile parameter in a similar

way to the HD Port parameters in Section D, Step 3.

H) Add ARP Proxy in Web Browser

Interface

To satisfy the needs of network stations trying to determine

Ethernet addresses for stations on the other side of the RF

link, the transmitter or receiver responds to ARP requests

with its own MAC address for any IP address added to the

Proxy ARP table. To add an IP address to the Proxy ARP,

perform these steps:

1. Plug your PC’s Ethernet cable into the back panel

LAN/WAN connector of the transmitter.

2. On your Web browser interface, go to the IP address

you configured on the front panel for your LAN port

(Section E – Configure LAN Port).

3. When prompted to log on, type the default User name

(“admin”) and default Password (“admin”).

4. On the Web browser interface, go to Network |

ARP/Proxy ARP.

5. Click

on the upper right of the Proxy ARP Table.

The Add an IP Address dialog box appears (Figure 9).

Figure 9. Add an IP Address Dialog Box

6. Type the IP address to be added.

7. Click Add Address to save this address to the Proxy

ARP Table.

8. Repeat Steps 6-7 to add additional IP addresses.

9. Click Close or

to exit the dialog box.

10. Repeat Steps 1-9 with your PC’s Ethernet cable

plugged into the receiver to set up proxy IP addresses

for the receiver.

Section 2 – Functional Design

2.1 General System Description

The HD Link studio-to-transmitter link (STL) is a transmitter and receiver pair that transports high

quality audio using digital technology over a microwave radio path. Designed for both current analog

and HD Radio

®

, STL applications, the HD Link system can transport multiple channels of high quality

linear (uncompressed) audio or Enhanced apt-X compressed audio, along with HD Radio and other IP

and Ethernet traffic.

In the U.S., FCC Rules Part 74, Subpart E, authorizes a 944-952 MHz band for over-the-air transport

of audio program material. Commonly licensed bandwidths include 200, 300, and 500 kHz. The

theoretical maximum amount of data carried depends on the type of modulation chosen for the link.

In Canada, the 953-960 MHz band is used for the same purpose with bandwidths of 250 and 375 kHz.

The HD Link system supports all these frequencies and bandwidths with a selectable radio frequency

(RF) power output from 1 to 5 watts.

The HD Link digital radio uses digital quadrature amplitude modulation (QAM) with 32, 64, 128, or 256

QAM and low-density parity check (LDPC) coding type forward error correction (FEC). This modulation

and advanced FEC provide very high spectral efficiency (amount of data sent over a given RF

bandwidth), robustness, and high RF gain. This state-of-the-art radio technology provides the highest

performance RF STL available today.

2.2 High Definition (HD) STL Development

2.2.1 Modulation

Analog 950 MHz studio-to-transmitter links transport the baseband FM composite signal. A digital STL

offers significant advantages of flexibility, reliability, and quality. It can multiplex multiple user

channels—such as high quality audio, data, and Ethernet traffic—over the same 950 MHz RF link. The

digital component makes multiplexing seamless; there is no crosstalk or degradation between

adjacent channels. A digital STL also gives errorless end-to-end data transport, unlike analog STLs,

which have some degradation of the RF signal.

The quadrature amplitude modulation (QAM) scheme is widely used in digital STLs and other

communication applications. In digital telecommunications, QAM data is sent as binary symbols in a

grid with the number of points in the grid equaling a multiple of 2 (2, 4, 6, 8, and so on). Here are

common QAM forms:

● 32-QAM

● 64-QAM

● 128-QAM

● 256 QAM

By moving to higher-order symbols or constellations, you can transmit more bits in the same RF

bandwidth. In doing so, however, the mean energy between points in the QAM constellation becomes

closer together and more susceptible to noise. So, a higher order QAM can deliver more data than a

lower-order QAM but results in a lower signal-to-noise ratio (SNR).

In a practical QAM application, periodic pilot symbols are inserted in the payload. These pilots carry no

user data and are used for enhanced phase noise immunity and improved adaptation or acquisition by

the receiver. Carefully designing and optimizing the RF receiver can reduce the overhead used for pilot

symbols.

When a digital 950 MHz STL carries Ethernet data to broadcast HD Radio, some problems arise. The

next subsections discuss possible problems and how the HD Link system addresses and corrects them.

2.2.2 HD Radio Signal on an STL

The HD Radio signal depends on the location of the Importer and Exporter. Here are three scenarios:

● When the Importer and Exporter are both placed at the transmitter site, the STL needs to carry

one or more audio programs as well as a low-speed data signal for the Program-Specific Data

(PSD) and, if implemented, Advanced Application Services (AAS) traffic for data-only services.

● When the Importer is at the studio and the Exporter is at the transmitter site, the STL needs to

transport the Importer-to-Exporter (I2E) signal, a Transmission control protocol (TCP – duplex

connectivity) data signal that can run as high as 156 kbps.

● When both the Importer and Exporter are at the studio, the STL needs to carry the Exporter-to-

Exgine (E2X) signal. The signal is either one-way (User Datagram Protocol – UDP) or duplex (TCP)

and its bandwidth varies by the service mode in use (MP1, MP2, MP3, or MP11). With MP11 using

TCP, the STL needs about 330 kbps of duplex bandwidth for E2X transport.

All three scenarios require IP data transport along with audio and—at least in some cases—duplex IP

data transport.

2.2.3 Data Bandwidth Requirements

Depending on the HD component placement, the STL needs to transport up to 330 kbps of IP data

traffic with one or more program audio channels. For the main analog FM broadcast program, an

uncompressed linear stereo pair with 16-bit samples and 32 kHz sample rate requires just over 1

Mbps of bandwidth. When the sample rate increases to 48 kHz for 20 kHz audio, it requires 1.5 Mbps.

Well-established compression algorithms, such as in the MPEG and apt-X families, can reduce these

requirements considerably, but it is best to keep the STL uncompressed wherever possible to minimize

chances of compromising audio quality. Adding transport of auxiliary audio channels can raise total

data bandwidth requirements to over 2 Mbps.

2.2.4 STL Carrying Capacity

These basic factors affect the amount of data carried across the STL system:

● Amount of RF bandwidth available

● RF STL hardware used

● RF quality of the link

For a given RF link, a path study is conducted to determine the total required RF system gain, which

factors in parameters such as

● Antenna gain.

● Cable loss.

● Transmitter power.

● Over-the-air distance.

● Fade margin.

● Required bit error rate (BER).

The RF STL hardware plays a critical role in this system gain equation.

Design and optimization of a digital RF STL is a tradeoff between spectral efficiency and BER. The

difference in required signal-to-noise ratio when moving between different QAM orders is around 3 to

4 dB per step. For example, 128-QAM requires 3 to 4 dB more signal to achieve the same BER

performance as 64-QAM.

2 – Functional Design HD Link Installation & Operation Manual

Version 2, April 2010

Harris Corporation 2-3

Intraplex Products

There are several ways to increase a given RF link’s performance:

● Using a more powerful RF transmitter and/or higher gain antennas

● Optimizing the RF hardware circuits to

• Minimize circuit noise

• Reject unwanted signals

• Maximize receive signal sensitivity

● Adding forward error correction (FEC)

The first two ways are common to any RF system and present no special challenge in the design of a

combined FM/HD transport system. FEC essentially sends additional information on the link along with

the payload (audio and data) information and uses this additional information to detect data errors

and rebuild any missing information at the receive end. There are several types of error correction

available. However, FEC adds overhead to the total data transport requirement. When trying to

compensate for poor link quality caused by using high QAM orders, and using those high QAM orders

to carry more information, adding FEC can hinder the information rate gains. Therefore, the key is to

use the most efficient form of FEC possible, with efficiency defined as the ability to correct the

maximum amount of errors while sending the minimal amount of FEC overhead. One of the most

efficient FEC schemes is low-density parity-check (LDPC) codes or turbo codes.

In information theory, the noisy-channel coding theorem (called Shannon’s theorem) establishes that,

however contaminated a communicate channel is with noise interference, it is possible to

communicate digital data information nearly error free up to a given maximum rate through the

channel. The Shannon limit of a communications channel is the theoretical maximum information

transfer rate of the channel for a particular noise level.

While LDPC and other error correcting codes cannot guarantee perfect transmission, the probability of

lost information can be greatly lessened. LDPC was the first code to allow data transmission rates

close to the theoretical maximum, the Shannon limit. In fact, it has been shown that LDPC codes can

reach within 0.0045 dB of the Shannon limit.

In contrast to less efficient error correction schemes, such as Reed-Solomon, LDPC offers a clear

advantage in terms of performance for a given signal-to-noise ratio. Specifically, for equal amounts of

FEC overhead, LDPC requires 3 dB to 5 dB less signal for the same BER performance than does Reed-

Solomon. This difference can translate to using the next-higher QAM order while maintaining the same

BER and RF power level.

2.2.5 Data Quality

2.2.5.1 Network Layer

One of the core components of the HD Link system is its network layer capability, which works with

data bandwidth management to determine the quality of the data information transfer. The network

layer set of functionalities meets challenges of a typical STL transport application and integrates

advanced data networking features, thus providing a reduction in capital and operational expense. The

HD Link system contains an IP gateway architecture that support bandwidth management to efficiently

prioritize and transport critical and non-critical traffic across the STL system and be able to operate in

one-way as well as full-duplex link configurations.

Figure 2-1 depicts a high-level view of the functionalities in the HD Link system’s IP gateway. In

addition to core features, the platform manageability of this gateway contributes directly to minimizing

the device’s operational cost. The system’s support of standard network management protocol

functions (such as HTTP, SNMP, FTP, Telnet, and ICP), allowing for more effective troubleshooting and

management.

2.2.5.2 Data Bandwidth Management

The network layer moves the various types of data across the link in the most efficient way. The

integrated IP gateway manages the available bandwidth and allocates it appropriately among these

traffic types:

● Audio for the FM and, depending on component locations, the HD program(s)

● IP data for the I2E or E2X HD Radio signal

● Other IP data, such as control and management and even LAN traffic

As traffic from different sources converge on the IP gateway’s data plane, the gateway’s architecture

must support functionalities that filter unwanted Ethernet traffic, police and shape the incoming

Ethernet traffic, and finally prioritize traffic so that the low-priority traffic does not interfere with the

media-related traffic. To achieve this support, a committed traffic rate is allocated to the various

Ethernet traffic sources and to the digitized audio channels. The traffic from the audio source(s) is well

controlled and constant; it therefore does not require metering or policing. However, the Ethernet

traffic may be bursty or variable in rate, and it needs to be handled carefully.

Each IP stream (whether HD media or control traffic) entering the gateway’s Ethernet interface(s)

should first pass through an access control function, which only passes packets whose IP source and

destination address pair are configured as valid connection endpoints. This method prevents unwanted

traffic from a local subnet, including broadcast packets (that is, packets addressed to multiple

recipients), to enter the HD Link system and eat away at bandwidth that is allocated for the legitimate

media to be transported. Once the Ethernet traffic has passed access control, it needs to be prioritized

as either High or Low priority, based on either the physical port through which it has entered, 802.1p

priority, or the IP DiffServ code point.

A policing and shaping function ensures

● Any excess Ethernet traffic entering the system via a lower-priority port, such as general LAN

traffic, is discarded, thus preventing such traffic from interfering with the transport of the critical

audio and HD streams.

● The smoothing function accommodates instantaneous bursts of the HD’s media stream across the

allocated air bandwidth. Without this smoothing function, the transmission of instantaneous bursts

in the HD IP stream requires far greater air bandwidth.

Finally, a scheduling function should ensure that the strict priority is followed when queuing packets

for transport across the HD Link system.
