This work proposes the use of interactive digital TV as an interface for access to remote experimentation laboratories, because remote labs can fulfill the purposes of experiments in various areas of education, and digital TV can be used with interactive applications. The proposal described in this paper was based on the interactivity features of digital television systems, as well as on the particular aspects of remote experiments, underpinned by the theory of multiple intelligences and the patterns of interactivity of digital TV systems. The model resulting from this work guides the deployment of interactive TV applications to access remote experiments, and it seeks to provide individualized learning alternatives covering three Gardner's multiple intelligences in an interactive environment for remote experimentation based on using only the remote control, and bringing together the broadcast industry and the educational environment.

4. DTV + Remote Labs

5. Digital TV (DTV)
Video Quality: HDTV, 1920p, 16:9
Audio Quality: 5.1 channels, 48KHz rate
Multiprogramming: a flow in HDTV or many flows in SDTV
Mobility: small TV`s and mobile devices with digital signal
Interactivity: the new layer from broadcast with data flow for
applications

6. iTV System

7. Levels of Interactivity
(Soares; Barbosa, 2009)
Local Interactivity: App from data layer, only local navigations
(interactivity channel not required)
- World cup charts, programs info, static content
Unidirectional Interactivity: By the interactivity channel only simple
responses go to broadcast
- Quiz answer, researchs, voting reality shows
Bidirectional Interactivity: By the interactivity channel is possible send
and receive content, without broadcast
- Realtime news, weather forecast, dynamic content
Full Interactivity: By the interactivity channel, complex requests are
possible, controls the programming and interacts with the broadcaster
directly

8. Proposed Model

9. Proposed Model
Based in BBC Interactive Television
Style Guide (BBC, 2002):
- Sequence of color buttons
- Safe areas for visual and text contents
- Font family and size
- Usability patterns

10. Proposed Model
spatialknestheticlinguistic

11. Proposed Model

12. Conclusions
- The model is an alternative to traditional means of access
to remote labs
- It’s possible create DTV apps with FULL INTERACTIVITY
using remote experimentation
- It’s possible that remote labs and educational broadcasters
can be joined to provide the full interactivity through DTV
- The DTV and the remote control can be used to create
adaptive content for 3 of Gardner's multiple intelligences
theory

13. Further Researches
- To develop more apps for other remote
experiments
- Use the model in school environment
- Validate the model
- Unite the academic and broadcast industry
