  1. 1. JavaDTV Developer Event May 2009 Mauricio Leal SDN Program Manager Sun Microsystems 1
  2. 2. Agenda • Java and Interactive TV • TV Market in Brazil • SBTVD Forum • Use Cases • Specification and Architecture • Selected TV specific APIs • Benefits • Status 2
  3. 3. Java Vision Statement 3
  4. 4. Java Technology for TV is Emerging Java is Everywhere 6 Billion Java-Enabled Devices 1.8 Billion Java-Enabled Phones 3.5 Billion Java Cards 25 Million Java TV Devices 800 Million Java Desktops 180 Operators Deploying Java Content 4
  5. 5. TM The Java Community Has Created Tremendous Opportunity $110B Over 100MOver 2 Billion $2.2B In Related JDK Java Powered In Java IT Downloads Phones $4.5B App Servers Spending Java Mobile Game Market 1.25 Billion Java Cards 4 Million Deployed Multi-Function 700M Blu-ray Disc Digital TVs & Printers PCs with Devices Set-Top Boxes Java 5
  6. 6. Worldwide TV Trends • All TV is going digital > Cable, satellite, and broadcast undergoing analog to-digital transition > IPTV, Blu-ray, and, downloads are inherently digita • All TV viewing will require a device > Tuner, DVR, game console, PC, mobile phone, etc > All devices will have middleware • Total devices in the home are growing > One or two set-top boxes on primary TV(s) today > One or more on every TV tomorrow 6
  7. 7. Digital TV Standards Worldwide ACAP DTMS DVB-MHP/GEM OCAP Ginga-J GEM-IPTV ARIB B.23 CDC/FP/PBP/Java TV/JMF 7
  8. 8. Java in TV today • Cable Networks: OCAP / tru2way (CableLabs) • Terrestrial/Satellite: ACAP (ATSC), ARIB, deployments in Europa and Asia • Packaged Media: BluRay • IPTV (OpenIPTV Forum) • Brazil: SBTVD 8
  9. 9. Java and Interactive TV • Interactive Java TV Applications are available today: > BluRay > Tru2way > MHP • Used for Games, Menus, News ticker, EPG 9
  10. 10. Java and Interactive TV • Interactive TV = TV + applications • Java applications augment Audio/Video content • Applications and data are distributed together with A/V content • Application lifecycle synchronized with video timeline • Simultaneous execution of multiple applications, can communicate with inter- Xlet communication 10
  11. 11. TV Market in Brazil • Brazilian Digital Terrestrial & Mobile TV > 180M+ people, 55M+ TV > World's largest dual terrestrial/mobile TV deployment > World's 4th largest TV network (80M viewers/day) • Brazilian standards body: SBTVD • SBTVD requested Sun to create royalty free DTV specification 11
  12. 12. SBTVD Forum Sistema Brasileiro de Televisao Digital • Founded 2006 • Brazil's standardization organization • Aim: defining standard and regulations for successful implementation of the digital TV infrastructure in Brazil • Aligned interests between broadcasters, industry, government and universities • Ginga-J is the Java based middleware part of the standard • SBTVD teamed up with Sun to create royalty free JavaDTV specification 12
  13. 13. Ginga Middleware Specifications • Ginga-J integrates with the other components on the set-top box Middleware Specifications Ginga-J SBTVD APIs ARIB B.23 Bridge NCL (partial) Java DTV Specification Common Core 13
  14. 14. Ginga-J Specification • Brazil's standard for procedural middleware • Completely based on JavaDTV • Extends JavaDTV for the DTV Brazilian system: > System Specific Service Information API > Definitions for System Specific Locators > Bridge API for integrating with the Ginga-NCL engine > Interaction devices API > Asynchronous messaging API 14
  15. 15. Java DTV Specification • Feature parity with other Java specifications in TV space > Allows the same kind of applications • Resides on mature standardized JavaME specifications > CDC, FP, PBP, JavaTV (latest versions) • Integrates LWUIT widgets for a compelling user experience • Extensive API allows access to all aspects of digital TV settop boxes 15
  16. 16. Use Cases • Online purchase of Audio & Video content • Interactive Advertising • Sport Statistics • Clips Download • Real-time voting • Quizes / Games (also with external devices) • Localized Information (such as Weather or Traffic) • Portal Applications • E-Government 16
  17. 17. Media APIs Application Management Error Reporting Broadcast Filesystem MPEG Concepts MPEG Section Filtering ARIB extensions Tuning Network Device User Settings & Prefs JavaTV 1.1 Applications Java DTV Architecture Events Inter-Appl Communication CDC 1.1 / FP 1.1 / PBP 1.1 Content Security Resource Management Persistent Storage SBTVD Extensions TV Graphics UI Widget Set 17
  18. 18. Broadcast Carousel • Problem: > unidirectional and unreliable transmission not suitable for file transfer > Arbitrary service selection • Solved by repetitive transmission of files over the broadcast channel Broadcaster Transmission Set-top Box 18
  19. 19. Broadcast Carousel • Applications, sounds, images, etc. can be embedded into transport stream • For Java: > applications and their data resources are transmitted over broadcast carousel • Broadcast files will be available via local virtual filesystem • Events generated whenever new files appear, updated or deleted 19
  20. 20. TV Graphics: Display Model • TV display model and desktop model are different • Multiple screen planes (Source: Draft Standard SBTVD forum N06- 1) 20
  21. 21. Display model • Screen planes can be reserved exclusively by applications • Each plane can be individually scaled • UI widgets, text and graphics are displayed on the graphics plane • Display of static picture or video is selected with switching control plane at pixel level • Subtitles are superimposed on other planes 21
  22. 22. Java Media Framework • Java Media framework (JMF) is part of Java TV (JSR 927) > Defines Player and Controls concept > JMF player is used to control and display time- based media streams > Player is typically associated with a (hardware) media decoder > Controls are used to query or change the state of a player > Asynchronous model - State changes are reported via events to subscribed listeners > JMF only offers some basic controls: Audio gain, Video size, Media select 22
  23. 23. Additional JMF controls in DTV • DTV spec provides additional controls for: > Audio language > Closed captions / subtitles > Video format, clipping, aspect ratio and presentation > Video timeline > Dripfeed (progressive I- and P-frames) 23
  24. 24. JMF extensions 24

  28. 28. Ginga-J benefits • Designed to fulfill the requirements of Brazilian market • Allows for rich media content and user experience • Procedural language • Interface with the other components on the settop box > Ginga-NCL, ISDB transmission system, etc. • Royality free 28
  29. 29. Java DTV Benefits • Large Java developer community in Brazil > developer experience, low learning curve • Java Communities > User groups (JUG) • Mature development tools available from many vendors > Development Environments – Netbeans, Eclipse, etc. > SDKs for JavaME – Wireless Toolkit, PhoneME, Netbeans Wireless Plugin 29
  30. 30. Deployment Status • Specification published on in December 2008 • Specification approved in April 2009 • Today: Major broadcasters already transmit Ginga and JavaDTV applications in their signal • First commercial implementations on terrestrial TV settop boxes expected by end of 2009 • Strong momentum for the deployment Ginga-J based boxes as well as applications will make this joint effort a success 30
