  1. DASE ContentAuthoring SystemTVPLUSi™ Station Deok-jung Kim Aircode djkim@aircode.com

  2. Contents • 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 CDTV: ATSC Seminar

  3. 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

  4. 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

  5. What’s possible with DASE • Program dependent data service : • Example: Quiz, Sports CDTV: ATSC Seminar

  6. 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

  7. 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

  8. What’s possible with DASE • Data-only Virtual Channel with out A/V • Example: Game, Weather, Traffic, etc. CDTV: ATSC Seminar

  9. 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

  10. 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 CDTV: ATSC Seminar

  11. Resources for DASE Application • Human resources • Content producer • XDML Programmer, Java Programmer • Designer • DB Engineer • System Engineer • Equipments • Graphic tool • Programming tool • Head-end Server System (PSIP,MUX,REMUX,Modulator…etc. ) • Content Providers • Various DBMS and DB Schema • DB or System Engineer CDTV: ATSC Seminar

  12. Typical Head-end system KBS Head-end System CDTV: ATSC Seminar

  13. 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. CDTV: ATSC Seminar

  14. TVPLUSi™ Station CDTV: ATSC Seminar

  15. TVPLUSi™ Author • Designed for designers • Market tested in rigors of actual deployment • Support for real-time content: Key benefit in World Cup, Asian Game • Features • Easy-to-use graphics user interface (GUI) • Import images created by popular 3rd party tools • Color preview simulation allows view of content’s color as it will appear on client STB • ‘master page’ that can lessen workload • ‘widget’ makes modifying contents easier than ever • Convenient TV resizing to place Audio Visual anywhere CDTV: ATSC Seminar

  16. TVPLUSi™ Author • Default library of images • Preview simulator • Code generation • output format : source code, not only byte code • Optimization: Code, graphic, palette • Automatic ‘same image scan’ optimize content size • Automatic AWT graphic generation reduces graphic size • In-house vector drawing graphic engine • Automatic control of MPEG2 i-frame • Hardware Abstract Layer ( different STB H/W) • Built-in real-time data encapsulation • Real time application data update interoperate with Aircode’s dynamic content server CDTV: ATSC Seminar

  17. TVPLUSi™ Verifier • Portable all-in-one system capable of transmission and STB interoperability testing of iTV contents that integrate data broadcasting system and digital broadcasting system • Proven in market as indispensably effective tool to verify content before live broadcast • Features(in case of ATSC-DASE) • Generate PSIP/SDF • Inject data carousel, addressable section encoded data into Mux or ReMux • Pump MPEG-2 SPTS, MPTS • Embedded DASE data encoder • SMPTE-310M TS output • Digital Video Storage: > 20GB Ultra DMA • PCI type 8VSB Modulator CDTV: ATSC Seminar

  18. TVPLUSi™ DCS • Real-time application server • Provides input gathering and editing interface for multi content provider’s data • Provides dynamic contents transformation through synchronizing with various external format(DB,XML,Text…) • Provides minimized and practical real-time service situation by enhancing with TVPLUS i ™ Verifier • Input format • DB(Oracle, Sybase,..ODBC), Text file, XML, AAT(TVPLUS i™ Author) • Output format: text, XML • Output : TVPLUS i™ Verifier, TVPLUS i™ Server CDTV: ATSC Seminar
