IBC Amsterdam
T-Systems is the technical provider of
this trial. The DVB-H data stream from
T-Systems HQ in Berlin is transmitted in
four largest German cities and up to 14
TV channels and 8 radio programs are
available.
Successful DVB-H trials in Munich with
MAYAH’s IO [io] 8001
Ongoing DVB-H trials in Germany launched
for the Football World Cup confirm a
growing interest within industry as well as
with end users for MobileTV technology.
MAYAH IO [io] 8001 Audio Video En/
Decoder are currently in use by Germany’s
largest telecommunications system
integrator T-Systems and by the Bavarian
TV “Bayerischer Rundfunk” (BR) to encode
several TV channels into the DVB-H
compliant IP-stream.
Bayerischer Rundfunk ran its own pilot
DVB-H project in Munich, providing
access to three public channels – ARD,
ZDF and it’s own channel BR. After
receiving the signal from the main control
room via an SDI interface, MAYAH IOs
encode it and pass the IP stream to a
Rhode&Schwarz DIP010 IP inserter and
encapsulator. Now ready for transmission,
the signal is transported via BR’s own
network to a transmitter at the Olympia
Tower in Munich. BR uses one of its own
frequencies for DVB-H.
Lucky owners of DVB-H enabled mobile
devices are able to receive a reliable signal
in Munich and for few kilometers outside
– indoor, outdoor and on the move. At
the edge of a coverage zone there is no
indoor reception at the ground level. The
sharp and stable picture is very convincing
at these relatively low resolutions. Even
during the full frame shots of the football
stadium you see the main attraction – the
ball.
Current DVB-H specifications require
MPEG-4 H.264/AVC video and MPEG-4 HE
AAC audio compression algorithms, a video
resolution of 320x240 pixels and a frame
rate from 12,5 to 25 / 30 fps. Reduction
of the original picture size and change of
a frame rate may cause inaccurate picture.
In order to avoid this and to provide the
first MobileTV users in Germany with
the best possible picture quality, MAYAH
used sports and football video material for
subjective evaluations along with a typical
technical tests.
The two largest German public TV channels
broadcast all major games at the Football
World Cup and enabling viewers in Munich
to choose between the broadcasting of
Bavarian Television and the joint project of
all four Germany mobile phone networks
operators.
MAYAH products have also been used by
TDF in Paris where all radio programming
is encoded with MAYAH Centauri II Audio
Gateway Codecs, and by T-Systems during
the CeBIT 2006 in Hannover for encoding
both TV and radio programs.The programs
are transmitted from five sites in Paris
including the world-famous Eiffel Tower to
cover the capital city from 12,5 km North
to South and 17 km from East to West.
To let the end-user efficiently receive the
digital video and audio content Sagem
developed a prototype DVB-H Terminal
MyX-8 DVB-H especially for this project.
MAYAH @ Formula 1 races
The Pope’s visit to Bavaria
MAYAH Centauri II Audio Gateway Codecs
were chosen by RTL television to provide
all technical and editorial communication
during the live transmissions of all
Formula One races in 2006 for German
audience.
From September 9 till 14 Pope Benedict
XVI will visit Germany and travel through his
Motherland Bavaria. People in this mostly
catholic part of the country await this visit
with a particular enthusiasm. However the
live transmissions of every public event
Last year MAYAH solution successfully provided high quality wireless audio communication via 3G/UMTS as the Pope Benedict
XVI was visiting Cologne and the World
Youth Day and was preaching from the ship
on the Rhein river.
New remote control software release
In addition to minor bug fixes and feature
upgrades, the Remote Control Software for
MAYAH Audio Codecs now provides extended function access as well as multichannel
level monitoring.
A full list of updates including the newest
Remote Control Software (version 3.2.0.4.)
are available at: www.mayah.com/remote/
At all circuits including the season
opening in Bahrain MAYAH Centauris
transmit from RTL OB Vans at the race
location to the broadcaster headquarters in
Cologne, mostly over ISDN. In some cases
like a circuit in Melbourne, Japanese
races or European Grand Prix at the
Nürburgring an IP-route over satellite was
applied. Phonebook of the Centauri II with
a profiles assigned to each entry allows
quick and comfortable switching between
different setups within seconds, via front
panel, windows remote software or webremote.
According to the broadcaster information,
current audience of each Formula 1
transmission in Germany exceeds 9 million
viewers.
with the participation of the Pope will be
on air on the both main German public TV
Channels – ARD and ZDF.
More than 200 cameras will follow Benedict
XVI on his way in Regensburg, Munich and
smaller Bavarian towns like Altötting, Marktl
and Freising. Production teams of ZDF
and Bayerischer Rundfunk (Bavarian Public
Television and Radio), being in charge of
ARD, have rented more than 70 additional
MAYAH Centauri II Audio Gateway codecs
to completely cover their needs for technical
and editorial communication between tens
of the OB Vans, SNG points and the main
control rooms.
The Web Remote software has also been
updated and can now access all MAYAH
Audio Gateway Codecs. Please refer to the
manual for information on how to access
the platform independent Web-Remote.

SIP – Session Initiation Protocol (RFC3261)
The s-box 7900HD
Features
IO [io] uses an optimized H.264
codec of the highest quality to
obtain the lowest possible bit rates
using CABAC, Loop filter, Lookahead, scene change detection and
5 complexity modes to adjust for
certain platforms. It supports all
frame rates in 1 frame increments,
particularly 12.5 fps for mobileTV,
and is compatible with nearly all
Handheld TV devices.
Developed by the IETF as an alternative
to the H.323 Standard, SIP, when used
with other protocols, can establish,
control, terminate and modify point-topoint and multipoint connections.
is the most advanced and versatile IP
Set Top Box currently available;

MPEG-2 High Definition video
decoding at up to 1080i/p.
■
Multicast Streaming
(via MPEG-2 Transport Stream)
■
HTTP Streaming
■
As a client-server protocol, SIP is similar
to HTTP. Its requests and responses are
text strings containing the information
about conversation signalling.
Amongst its wide range of features is
an optional 3.5 HDD for local content
storage and, by adding an optional PCI
DVB-S/T/C tuner card, IP encapsulated
content can even be pushed via
satellite transmission.

SIP is responsible for all connection
signalling, localisation of users and
registration. Quality-of-Service, directory
access, as well as description of the
session and conferencing are not handled
by SIP, rather by other protocols.
SNG – Satellite News Gathering
The key to SNG over IP is a low
bit rate coupled with low latency.
The IO [io] 8000/8001 offers
“end-to-end” latency, with its
highly efficient MPEG 4 H.264/
AAC HE encoding, starting at just
250 ms (plus satellite link) and
with just half the bandwidth of
MPEG-2.

The modular structure of SIP enables
smooth co-operation with H.323. The
calling side can localize its partner
and signalise, that communication
will be handled by H.323 protocol.
Since SIP only provides the framework, a
number of other protocols can be utilised
to support and expand its functionality.
Some of these are:
ipTV / Webcasting / Corporate casting
IO [io] 8000/8001 delivers ISMA

Streaming Protocols
MAYAH’s long experience with audio via IP
has enabled our products to make use of
a huge range of protocols, allowing them
to be easily integrated into nearly any
type of streaming environment.
The following are just some examples of
this diversity:
Optional ASI In & Out
Optional 2nd (Dual)
Ethernet port
Redundant Power Supply options (here AC and DC)
ASI IN and OUT
ISDN & Dedicated Lines
Flexibility
ASI interfaces enables CENTAURI to work
in DVB environments. According to DVB
A010 rev1 and EN50083-9, the output
interface with two ASI ports in BNC,
provides a variable payload datarate of 0 –
214 MBit/s for an MPEG 2 Transport
Stream (MPEG TS) within the 270 Mbit/s
physical ASI link data rate.
Depending upon its current application,
CENTAURI II can be equipped with either
2 or 4 ISDN BRIs. Supporting a variety of
international D-channel protocols, the
CENTAURI II can be used in any ISDN
network around the globe. For dedicated
lines CENTAURI II supports a dual X.21/
V35 interface.
If additional data needs to be transported
with the audio, the RS232 port can
input/output ancillary, asynchronous data
while the contact closure facility supports
8x opto In and 8x relay Out for the
control of remote devices.
Dual Ethernet
Redundant Power Supply
Two 10/100 electrical Ethernet ports are
available to connect the codec with IPnetworks for audio-via-IP and remote
control. The interfaces can be dual
electrical or electrical/optical; particularly
useful for applications transporting audio,
allowing audio and control to be managed
via separate logical networks, e.g. SNMP.
An alternative use for Dual Ethernet is for
fully redundant audio streaming.
A redundant, hot swapable power supply
is optionably available in the combinations
AC/AC, AC/DC and DC/DC to meet the
broadcasters and telcos requirements for
a fully redundant power supply system.
AC wide range module: 90-260 VAC,
47-63 Hz. – DC module: 36-72 VDC –

Particularly interesting for studio environments is the Silent Codec Cooler with its
ultra low noise cooling fan.
The Eurovision Song Contest has been
the largest annual pop-music and media
event in Europe for exactly 50 years.
Current TV audiences for the show average
100 million viewers. On 18th and 20th
May 2006 the show took place at the
Olympic Indoor Arena in Athens, Greece.
37 countries sent their best artists to
take part in the competition and the
scale of the technical preparations this
year was larger than ever before.
To unify the support workflows, MAYAH’s
MERK II Portable Gateway Codecs were
chosen for their reliability, flexibility
and ease-of-use by the technical
supplier of the event TVN (Germany).
Installed in every commentary booth,
the MERK II transmitted journalists
voices via ISDN networks directly to
the national TV channels control rooms.
Special channel mapping was prepared to
provide the journalists with a comfortable,
headphone based monitoring environment.
Function buttons on the MERK II’s control
panel were used for special presets,
including an automatic “SOS call” for
technical support; this wasn’t engaged
even once during the whole event!
