MAINDATA was established in 1996 as a spin-off from FINSAT a joint-venture for real-time financial
data distribution. MAINDATA is focused at IP DataCasting Technologies.
In 1996 MAINDATA started providing DataCasting services via Analog TV inserting data into a VBI
(vertical blanking interval) via VTV Television at Eutelsat Satellite.

How DVB-H achieves Mobile reception ?
DVB-H accomplishes Reception to Mobile Handsets by modifying
DVB-T transmission by adding:
1) Time Slicing
2) MPE FEC
3) Time Interleaving
4) 4k COFDM mode
These features are incorporated in different elements of the
network.

Why DVB-H ?
•
DVB-H enables delivery of Mobile
TV (news, sport, music) to a light,
battery powered mobiles handsetslike GSM phones.
•
DVB-H channel bandwidth can
range from 2 to 10 Mbps while
single small screen TV channel
bandwidth H.264 encoded is roughly
200 kbps. So DVB-H can carry 1050 TV services over a single
transport stream.
•
DVB-H is low-cost delivery
mechanism for mobile TV services
to complement existing mobile
phone services.
•
DVB-H can be broadcast over
DVB-T networks launched already
•
Mobile TV presents a new media
wave.
www.maindata.info

MAINDATA
Mobile TV, Mobile Video Streaming and Broadband Portable Internet
Why DVB-H ?
•
3G networks are unable to accommodate large
numbers of users as well as provide high
enough bitrate for TV services (HSDPA
enhancement is required).
•
DVB-H requires moderate investment to
existing network
•
It is vital for mobile operators to seize firstmover advantage and take a proactive role in
defining the future value chain.

DVB-H services launch timing
There are numerous trials and demos of DVB-H
networks around the world in 2004, 2005:
•
USA, Pittsburg
•
Berlin
•
Finland
•
Singapore
•
UK O2
•
Australia
•
Spain
•
Switzerland
•
Hungary
First commercial deployments are expected in
2006 when variety of DVB-H handsets will be
available.

MD DVB-H & 3GPP Platform for Mobile Television & Video Streaming
DVB-H is suited for Mobile
TV IP Multicast services
3GPP – 3rd Generation
Partnership
GSM 3GPP networks are
suited for Video Streaming –
Unicast
These services are
compliant to each other.
While Television services
does not make sense to
broadcast via multiple
Unicast connections but
rather via DVB-H, video-ondemand or private video
streaming (e.g. home
supervision) does not make
sense to transmit over DVBH network but rather via
Unicast 3GPP network.
Both standards have a common IP layer both use RTP (IP Real Time Protocol) and similar ESG
(electronic service guide) and DRM (Digital Right Management).
Integration of both networks makes perfect sense to simplify Mobile Service Provider operation and
content management.

Time Slicing – To prolong a battery life - a key DVB-H feature !
Mobile DVB-H Handsets has to be able to operate for at least 90 minutes with a goal of 3 hours.
When transmission is split to time slices, handset can perform most energy demanding operations
like reception, FEC etc, only during a fraction of time, only when service for given handset is
transmitted.
Thus time slicing provides effective method for reducing power consumption.
Thus by time slicing handset can save 90 % of energy.

Time Interleaving – Impuls Noise protection
Time Interleaving is currently implemented in
Japanese ISDB-T standard and
European DAB (Digital Audio Broadcast) standard
This feature effectively protects signal against impuls noise.
Both of these standards were better than DVB-T for mobile reception.
By adopting this technique into DVB-H standard it becomes adequately suitable for
mobile transmission.

4k mode - to fill a gap between 2k and 8k
Currently DVB-T standardizes either 2k or 8 k mode (# of subcarriers).
2k is more robust for mobile transmission while 8 k has higher bitrate and larger coverage
area.
ISDB-T currently supports 4k mode which seems to be better trade-off for mobile services.
