• Single-tone audio modulation

• Adjustable modulation index

• Adjustable power and frequency

•“.wav” can be played as a modulator

• Stereo or mono

• Adjustable deviation and modulation

• Pre-emphasis: 25µs ,50µs, 75µs or OFF

Data over FM: RDS & DARCRDS: Europe, North America

• The modulation is a form of bi-phase shift keying (BPSK) ±90º

• Data rate of 1187.5 bps at 57 kHz (730 bits/sec usable)

• Program Identification code (PI)

• Program Service name (PS)

• Program TYpe code (PTY)

DARC: Japan, ETS 300751: Europe• 76kHz LMSK ( Level Minimum Shift

Keying) subcarrier at 10%

• 16 kbps (8.9kbps usable), which is equivalent to approximately 1000 characters received per second

• Introduced by NHK; highly popular in Japan

• VICS is over DARC. Same purpose

27

• Alternative Frequency lists (AF)

• Traffic Message Channel used RDS to transmit info on road condition &

traffics

• Low penetration in North America

• VICS is over DARC. Same purpose as TMC but for Japan only

• ETS 300751 is used mainly in France for news, traffic and DGPS.

Data stream files are provided by a multiplexer that combines a ll radio services, Program Associated Data (PAD) data and video. The m ultiplexing technology and data-framing structure is NOT in the public domain for proprietary standards such

as Sirius, XM & IBOC. DAB, DRM & ISDB-Tsb are in th e public domain.Modulation is required to transmit the data stream over the air. There are two types

of modulation: QPSK for satellite transmission and COFDM for terrestrial transmission.

Data files are data streams stored as a file on a h ard disk. Waveform files are composed of waveform samples similar to *.PCM or *. WAV audio content.

IBOC, Sirius, XM: Test files are provided by them

AVERNA has 4 products covering this family:

• DenMUX: This is a multiplexer that includes audio v ideo CODEC MPEG 2 and DMB for video to build a multiplexed fil e ready for modulation.

• Library of DAB/DMB from around the world. This is a very useful tool to validate that a DAB/DMB receiver will work in various countries with various type of content. Examples of these actual broadcast are:• TMC, TPEG

36

• TMC, TPEG• DMB, DAB+ (AAC)• Various Broadcast of Multimedia Object Transfer (MO T)• “Live Broadcast” from Australia, Korea, Germany, etc

• DAB ETI: This is the DAB/DMB modulator that will br ing the ETI file in RF.

• DAB Waveform player is a low cost IQ samples reader for use in manufacturing for testing DAB/DMB receiver

Testing of satellite (SDAR) signal: Test files from Sirius & XM

• A limited number of official test files are provide d by Sirius and XM• One URT (Generator) can produce one of the three (S irius) or six (XM) channels at a given time with standard PCI architec ture. Multiple beams are possible.

• These are data files: Two modulators are required in your signal generator: one for the satellite or QPSK modulation , and another for the terrestrial or Coded Orthogonal Frequency-Division Multiplexing (COFDM) modulation

• Only Sirius and XM can generate the transport strea m data files. Radio manufacturers are unable to create their own files.

manufacturers are unable to create their own files.

Sirius: Test files from Sirius & manufacturing appr oach

• Only one type of test file for almost all test: TMT 11-03 for GEN 2 & TMT23-03 for GEN 3 chip receiver

• Sirius provides license key to unlock files for 1 y ear• Legacy files TRDT11-02, TRDT23-02 can be read. Old er files require special

permission from Sirius. (eg. TRTT-01, DRAT-03)• Sirius is promoting RX00100 & multi-tone audio anal ysis for manufacturing• Sirius is porting BER measurements over the URT (Bi g DipBer)

HD Radio IntroductionHD Radio IntroductionHD Radio IntroductionHD Radio Introduction

IBOC FM Spectrum (Primary, Non-Extended)

IBOC radio was developed to superimpose CD-quality radio over the existing analog transmission by adding digital modulation on each side of the existing analog spectrum bandwidth. The content of both transmissions is identical. Multicast is possible on FM.

IBOC Test Files

• IBiquity, the owner of the IBOC or HD Radio technol ogy, provides waveform test files

• Although generating multiple channels simultaneousl y is possible, the current release only produces a single AM or FM cha nnel except in the presence of an adjacent interferer. .• Ibiquity is coming soon with multi-channels waveform files that are already supported by the URT ( Rev. 3).

already supported by the URT ( Rev. 3). • Some test files exceed 2 gigabytes• Radio Manufacturer cannot create their own test fil es• Over 100 official test files are provided (>30 GB)• URT is certified by Ibiquity

• The RF Player can also playback files from standard recorded libraries:

• Digital TV Labs (UK) recordings of live DVB broadca sts in Europe

• Advanced Television Test Center (ATTC) recordings o f live ATSC broadcasts in USA
