• MULTIMEDIA SYSTEMS INTEGRATE

ALL THE COMPONENTS DESCRIBED

IN THIS COURSE:

- SERVERS

- NETWORKS

- CLIENTS

- SOFTWARE

- CONTENT

MULTIMEDA SYSTEMSIREK DEFEE

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?

MULTIMEDA SYSTEMSIREK DEFEE

EXAMPLE: MOBILE MEDIA DEVICES

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

MULTIMEDA SYSTEMSIREK 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 SYSTEMSIREK DEFEE

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:

MULTIMEDA SYSTEMSIREK DEFEE

WE WILL HAVE VARIETY OF TERMINALDEVICES....

MULTIMEDA SYSTEMSIREK DEFEE

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

MULTIMEDA SYSTEMSIREK DEFEE

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

MULTIMEDA SYSTEMSIREK DEFEE

IN FACT WE CAN SEE THE WIRELESS NETWOKRSAS HIERARCHY

MULTIMEDA SYSTEMSIREK DEFEE

HERE THE BANDWIDTH GROWS

HERE WE MOVE TO IP PROTOCOL

HERE ARE DIFFERENT NETWORK TYPES

MULTIMEDA SYSTEMSIREK DEFEE

From Telephone to Internet

• Telephone network for speech

• Internet for data and… everything

WLAN

IP networking is the future

MULTIMEDA SYSTEMSIREK DEFEE

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

MULTIMEDA SYSTEMSIREK 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 SYSTEMSIREK DEFEE

Why mobile TV may be different

MULTIMEDA SYSTEMSIREK DEFEE

WHAT NEW MOBILE TV MAY OFFER

IT MAY SERVE AS PORTAL TO SERVICES

TOURISM PORTAL

TRAVEL PORTAL

PORTAL INTERFACE

MULTIMEDA SYSTEMSIREK DEFEE

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….

MULTIMEDA SYSTEMSIREK DEFEE

What is mobile device?

camera camcorder TV radio game PDA

makeup device? Swiss army knife?

MULTIMEDA SYSTEMSIREK 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 SYSTEMSIREK DEFEE

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

MULTIMEDA SYSTEMSIREK 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 SYSTEMSIREK 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 SYSTEMSIREK DEFEE

And the final destination...

TECHNOLOGY MAY BECOME INVISIBLE

LONG IN THE FUTURE….

MULTIMEDA SYSTEMSIREK DEFEE

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.
