  • DASE Application vs. Internet Application

  • What’s possible withDASE

  • Dynamic Content: The Real World

  • Set-Top-Box: the other half

  • Resource needed for DASE Applications

  • Cost Effectiveness

  • DASE Experience

Itv dase vs internet
iTV (DASE) vs. Internet

  • TV is relax media but PC is intensive media

  • Internet always online, TV is broadcast defined

  • Internet (PC) Application runs on more powerful H/W then DTV

  • DASE: 1 page browser, Internet: scrollable.

CDTV: ATSC Seminar

What s possible with dase
What’s possible with DASE

  • Program dependent data service:

    • Contents and applications selected to maximize relevancy and compelling complement to A/V content

    • Example: Music, Drama

CDTV: ATSC Seminar

What s possible with dase1
What’s possible with DASE

  • Program dependent data service :

    • Example: Quiz, Sports

CDTV: ATSC Seminar

What s possible with dase2
What’s possible with DASE

  • Program independent data service with A/V

    • Normal DTV program will include data services.

    • Weather Service, Stock Service, etc.

CDTV: ATSC Seminar

What s possible with dase3
What’s possible with DASE

  • Data-only Virtual Channel without A/V

    • Low cost ; no A/V

    • Needs to be highly attractive and useful

    • Example: Education, Game

CDTV: ATSC Seminar

What s possible with dase4
What’s possible with DASE

  • Data-only Virtual Channel with out A/V

    • Example: Game, Weather, Traffic, etc.

Dynamic content the real world
Dynamic Content: The Real World

  • Dynamic data delivery protocol in DASE Specification

    • Addressable section

    • Carousel update

    • Stream event

  • Application must be able to handle dynamic data

  • Dynamic data pushing system

  • Data Gathering from 3rd data source

    • Various database formats

  • Testing/Verifying System and Environment

CDTV: ATSC Seminar

Consideration of set top box
Consideration of Set-Top-Box

  • Environment Limitations

    • CPU power: 200MIPS – Pentium, 100Mhz; Memory

    • Middleware optimization

  • Font - unpredictable layout concerns

    • Metrics

    • Screen resolution (DPI): 72DPI – 1:1 Pixel/pt, optimized resolution

    • Outline font

  • Content Size

    • Images and Text data

    • STB available memory

    • Bandwidth: range 1Mbps ~ 500kbps

  • Color depth and color palette: safe zone: 256. Compelling content need > 16bit color

  • Remote control

    • Color button order

    • Navigation: Direction Key , Pointing device (mouse type)

  • Overlap policy of translucent with AWT Graphic and Image

Cost effectiveness
Cost Effectiveness

  • Authoring tool

    • For Non-engineers: Designers, non Java/XDML programming ability

    • Re-usability

    • Quick to make DASE Application

    • No education cost. For DASE and Java, XML…

  • Testing Head-end System: verifier

    • Simple : low cost broadcasting equipment

    • Easy to use : no system engineer

    • Immediately inject data and cast to STB for reduce testing time and effort.

  • Dynamic content connection with Content Provider : DCS

    • Universal dynamic content server

    • XML, DB, Text format data input

    • Various DB connectivity

    • Easy to use : no system engineer need.
