MULTIMEDIA SYSTEMS
PERSPECTIVES
MULTIMEDA SYSTEMS
IREK DEFEE
• MULTIMEDIA SYSTEMS INTEGRATE
ALL THE COMPONENTS DESCRIBED
IN THIS COURSE:
- SERVERS
- NETWORKS
- CLIENTS
- SOFTWARE
- CONTENT

WHAT WILL BE THE FUTURE IN MULTIMEDIA
SYSTEMS?
WHAT IS HAPENNING RIGHT NOW IS THAT
NEW TECHNOLOGIES AND MULTIMEDIA
SYSTEMS ARE COMING ALL THE TIME,
ESPECIALLY IN THE MOBILE AREA
-TERMINALS
-NETWORKS
-SOFTWARE
MULTIMEDA SYSTEMS
IREK DEFEE
Historical development
1610
2160
From mobile phone
N-Gage
Internet Tablet 770
to
no-mobile phone?
MULTIMEDA SYSTEMS
IREK DEFEE
EXAMPLE: MOBILE MEDIA DEVICES
MOBILE PHONES ARE EVOLVING INTO MEDIA
DEVICES. THEY MAY CHALLENGE PHOTOGRAPHIC
CAMERAS, VIDEO CAMCORDERS, PORTABLE MUSIC
PLAYERS, GAME CONSOLES
MULTIMEDA SYSTEMS
IREK DEFEE
Heterogenous networking
From GSM radio network via Bluetooth to…
WIRELESS BROADBAND or…
From tens of kilobits to megabits per second
3G onboard
WLAN onboard
TV onboard
ALL onboard
MULTIMEDA SYSTEMS
IREK DEFEE
SO WE MAY THINK THAT MOST DEVICES
IN 10 YEARS TIME WILL BE MEDIA DEVICES
AND CONNECTED BY WIRELESS.
HOW THIS MAY HAPPEN? IN THE FUTURE
WE WILL HAVE HUGE RANGE OF APPLICATIONS
AND SERVICES:
MULTIMEDA SYSTEMS
IREK DEFEE
WE WILL HAVE VARIETY OF TERMINAL
DEVICES....
MULTIMEDA SYSTEMS
IREK DEFEE
NETWORKING PLATFORMS WILL BE
INTEGRATING – ONE DEVICE WILL BE
ABLE TO CONNECT TO DIFFERENT NETWORKS
MULTIMEDA SYSTEMS
IREK DEFEE
HOWEVER, ALL THESE NETWORKS WILL
BE BASED ON THE IP PROTOCOL:
MULTIMEDA SYSTEMS
IREK DEFEE
IN FACT WE CAN SEE THE WIRELESS NETWOKRS
AS HIERARCHY
MULTIMEDA SYSTEMS
IREK DEFEE
HERE WE MOVE TO IP PROTOCOL
HERE THE BANDWIDTH GROWS
HERE ARE DIFFERENT NETWORK TYPES
MULTIMEDA SYSTEMS
IREK DEFEE
From Telephone to Internet
• Telephone network for speech
• Internet for data and… everything
WLAN
IP networking is the future
MULTIMEDA SYSTEMS
IREK DEFEE
New data transfer ways
• From: person-to-person phone call
• To: Data center-to-mass public
- Broadcast TV
- Multicast Internet
3G MBMS
Multimedia
Broadcast &
Multicast
WLAN IP Multicast
DVB-H Broadcast
Massive distribution of content will be
possible rather soon
MULTIMEDA SYSTEMS
IREK DEFEE
The Broadcast case: DVB-H
• Mobile television system
• Can run with digital television DVB-T
• But it is also compatible with the
Internet
MULTIMEDA SYSTEMS
IREK DEFEE
Why mobile TV may be different
MULTIMEDA SYSTEMS
IREK DEFEE
WHAT NEW MOBILE TV MAY OFFER
IT MAY SERVE AS PORTAL TO SERVICES
PORTAL INTERFACE
TRAVEL PORTAL
TOURISM PORTAL
MULTIMEDA SYSTEMS
IREK DEFEE
The Music Case: Mobile IPod
IPod,
Portable
Music
Player
Music Web shop
Mobile Music device
with hard disc
Mobile device is an IPod, and phone,
and much more….
MULTIMEDA SYSTEMS
IREK DEFEE
What is mobile device?
camera
camcorder
TV
radio
makeup device?
game
PDA
Swiss army knife?
MULTIMEDA SYSTEMS
IREK DEFEE
What is still missing from this?
Which device is not integrated in
mobile media?
• The missing part is …. PC
What is a PC?
PC is a device with sizable display and keyboard
That is not possible with mobile device
MULTIMEDA SYSTEMS
IREK DEFEE
But… imagine this
Mobile devices are more and
more capable (processors,
memory, hard discs), resembling
PC from few years ago
UWB
Ultra Wide Band
Mobile device has wireless
links to keyboard and display
Bluetooth
MULTIMEDA SYSTEMS
IREK DEFEE
Ultra Wide Band Network
• Ultra Wide Band is wireless network
of very short range but with very
high data transfer rate (600 Mb/s to
1000 Mb/s and more)
This network can eliminate MONITOR
cable. Then mobile device can drive
the monitor directly.
MULTIMEDA SYSTEMS
IREK DEFEE
UWB opportunity
• If Ultra Wide Band system becomes
popular and monitors/TV’s will
get it, and if mobile devices will have
it, then they interface directly.
There will be no need for PC anymore
MULTIMEDA SYSTEMS
IREK DEFEE
And the final destination...
LONG IN THE FUTURE….
TECHNOLOGY MAY BECOME INVISIBLE
MULTIMEDA SYSTEMS
IREK DEFEE
CONCLUSIONS TO THIS COURSE:
WE WILL SEE HUGE PROGRESS IN MULTIMEDIA
SYSTEMS IN THE FUTURE.
SYSTEMS WILL BECOME MUCH MORE COMPLEX
NETWORKS WILL BE BROADBAND WIRELESS.
INFORMATION WILL BE DOWNLOADED ONLY
BY NETWORKS, PHYSICAL CARRIERS (LIKE E.G.
CD) WILL BE DISAPPEARING.
