Digital TV Still evolving
  • Giants of European Digital TV
  • UPC
  • Canal
  • Kirch
  • AOL Time-Warner
  • BSkyB Liberty Media

Analogue TV to Object-Oriented TV
  • First Car Benz 1885
  • Ten years of Horse-less carriages
  • Speed limits of 3.5 mph in UK until 1894
  • Mass-production 1908
  • Railroad Financial Bubble Burst in 1901

Need for Interaction
  • Level of Activity
  • Sleep
  • Cinema
  • TV
  • Car driving
  • Video game
  • Browsing
  • Office applications

Why change TV ?
  • Things are
    Changing !
  • Not only in IT, also in the Consumer Electronics
  • Application passive gt fully interactive
  • Functionality analogue gt object oriented
    digital
  • Architecture pure HW gt flexible HW/SW combi
  • In other words, going digital is now more that
    just digitising the content at the source.

11
Original Concept of DVB-MHP
12
Time-Shift Horse-less carriage
Increase PVR functionality, example
13
Your own TV channel
  • Not Video on Demand Too expensive
  • But a PVR Personal Video recorder IP link
  • Hard Disk module in TV or DVD players
  • 20-300- hours of video on a disk
  • Plus a Satellite tuner (400 channels)
  • Problem Commercials on TV
  • Problem Channel allegiance

14
Virtual Channels Who will do It
  • Who will create them?
  • Example Mercedes own TV Channels
  • Large committed audience (Elite)
  • Strong image binding
  • Rich
  • Need to be served
  • Others Mattel (Barbie), AH, Virgin,
  • The Life Styler
  • People you already trust

15
Traditional Sequential Video Broadcast The
script writer and director are in Hollywood
Generate compose/code transmit decode/render
16
increase digital TV functionality The users
agents will become the director
17
PDSL Role in TV Industry
  • This class of applications require extended
    software functionality in the terminal for
  • Electronic commerce content protection,
    security, payment and very important privacy
    protection
  • Advanced content support for MPEG-4, MPEG-7
  • User interfaces personalised, self-learning,
    Agents
  • Extension is ok, but we want to keep
  • Efficient transport in the broadcast channel
  • Put as much of the functionality in the terminal
  • Efficient execution of the applications
  • Embedded software allows for native execution
  • Consistency in the end-to-end system
  • Standardise the interfaces to these extensions

Requires the promotion of these extensions to
industry and standards bodies PDSLs role
18
Role of the lets
  • Open up the broadcast Web services industries
  • Like Imode applets opened the Japanese cellphone
  • Lets allow creation of adaptive content
  • Provide customised services to specific markets
  • But a Let will simply prove the service concept
  • A successful Lets functionality move to servers
    or terminal. Go Server. Go Native.

19
Platform extension Go Native

Holiday planning and execution
  • Phase 1 Watch TV to select plan the holiday
  • Compromises
  • Phase 2 General plan and arrangement
  • Phase 3 Load the Major-domo Agent-let
  • into the car/PDAs/phones/cameras Java devices
  • Phase 4 Go on holiday
  • Enjoy the holiday collect the evidence
  • Phase 5 Prove to everybody we enjoyed it.
  • Create the holiday web page and/or DVDs

22
Experience from Java Development
  • PDSL now CMM-3 for embedded system
  • Java makes integration easier
  • but only if the CM is well arranged
  • Test productivity not raised by Java
  • More effort in performance improvement
  • Security is an issue
  • API is a line that runs through the Architecture
  • Threads are extravagantly used by designers
  • Embedded platforms need strict execution
    architecture leadership in projects

23
Conclusions
  • Java is changing TV
  • Object oriented nature of content appears
  • Standardisation difficult Moving target
  • Goal is being moved by the technology/market
  • Java is not really helping the development
    process for embedded systems
  • Agent-Let interaction Aglets (IBM) need to be
    researched Security aspects
