MULTIMEDIA SYSTEMSPERSPECTIVES


• MULTIMEDIA SYSTEMS INTEGRATE

ALL THE COMPONENTS DESCRIBED

IN THIS COURSE:

- SERVERS

- NETWORKS

- CLIENTS

- SOFTWARE

- CONTENT


WHAT WILL BE THE FUTURE IN MULTIMEDIASYSTEMS?

WHAT IS HAPENNING RIGHT NOW IS THATNEW TECHNOLOGIES AND MULTIMEDIA SYSTEMS ARE COMING ALL THE TIME,ESPECIALLY IN THE MOBILE AREA

-TERMINALS-NETWORKS-SOFTWARE


Historical development

1610 2160 N-Gage Internet Tablet 770

From mobile phone to no-mobile phone?


EXAMPLE: MOBILE MEDIA DEVICES

MOBILE PHONES ARE EVOLVING INTO MEDIADEVICES. THEY MAY CHALLENGE PHOTOGRAPHICCAMERAS, VIDEO CAMCORDERS, PORTABLE MUSICPLAYERS, GAME CONSOLES


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

SO WE MAY THINK THAT MOST DEVICESIN 10 YEARS TIME WILL BE MEDIA DEVICESAND CONNECTED BY WIRELESS.

HOW THIS MAY HAPPEN? IN THE FUTURE WE WILL HAVE HUGE RANGE OF APPLICATIONSAND SERVICES:


WE WILL HAVE VARIETY OF TERMINALDEVICES....


NETWORKING PLATFORMS WILL BE INTEGRATING – ONE DEVICE WILL BE ABLE TO CONNECT TO DIFFERENT NETWORKS


HOWEVER, ALL THESE NETWORKS WILLBE BASED ON THE IP PROTOCOL:


IN FACT WE CAN SEE THE WIRELESS NETWOKRSAS HIERARCHY


HERE THE BANDWIDTH GROWS

HERE WE MOVE TO IP PROTOCOL

HERE ARE DIFFERENT NETWORK TYPES


From Telephone to Internet

• Telephone network for speech

• Internet for data and… everything

WLAN

IP networking is the future


New data transfer ways

• From: person-to-person phone call

• To: Data center-to-mass public

- Broadcast TV

- Multicast Internet

3G MBMS WLAN IP Multicast DVB-H Broadcast

Multimedia

Broadcast &

Multicast

Massive distribution of content will be

possible rather soon

http://www.nokia.fi/puhelimet/puhelinmallit/6630/


The Broadcast case: DVB-H

• Mobile television system

• Can run with digital television DVB-T

• But it is also compatible with the

Internet


Why mobile TV may be different


WHAT NEW MOBILE TV MAY OFFER

IT MAY SERVE AS PORTAL TO SERVICES

TOURISM PORTAL

TRAVEL PORTAL

PORTAL INTERFACE


The Music Case: Mobile IPod

IPod, Music Web shop

Portable Mobile Music device

Music with hard disc

PlayerMobile device is an IPod, and phone,

and much more….


What is mobile device?

camera camcorder TV radio game PDA

makeup device? Swiss army knife?


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


But… imagine this

Mobile device has wireless

links to keyboard and display

Bluetooth

UWB

Ultra Wide Band

Mobile devices are more and

more capable (processors,

memory, hard discs), resembling

PC from few years ago


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.


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


And the final destination...

TECHNOLOGY MAY BECOME INVISIBLE

LONG IN THE FUTURE….


CONCLUSIONS TO THIS COURSE:

WE WILL SEE HUGE PROGRESS IN MULTIMEDIASYSTEMS IN THE FUTURE.

SYSTEMS WILL BECOME MUCH MORE COMPLEXNETWORKS WILL BE BROADBAND WIRELESS.

INFORMATION WILL BE DOWNLOADED ONLYBY NETWORKS, PHYSICAL CARRIERS (LIKE E.G.CD) WILL BE DISAPPEARING.
