Abstract
Communities of Practice make intensive use of information and communication technologies (ICT) to meet their needs of interaction among their members. At present, the main supporting tool for these communities is the Internet and the software tools available for their users. With the advent of digital TV, however, new resources have become available to these interactive communities. This study aims at analyzing the basic needs of technology support for virtual communities, identifying the essential software services that can meet these needs and propose an application model for interactive digital television that can meet the main needs of a Community of Practice. To achieve that, the essential services for a Community of Practice were identified by means of a field research applied to a knowledge management Community of Practice in order to propose an application model for Interactive Digital TV to Communities of Practice. The results discussed here may be used to develop applications for Interactive Digital TV and Communities of Practice, exploring the interactive resources of this new platform.
Highlights
The introduction of the Brazilian Interactive Digital Television model may lead to the development of several applications and services, exploiting its interactivity resources
INTERACTIVE DIGITAL TELEVISION (IDTV) is a resource with a great deal of possibilities as it is not possible to determine exactly its scope [1]
Based on the results of this research, an application model for the Brazilian System of Digital Terrestrial Television for the CoP is proposed, covering the essential services previously identified. This model will serve as the basis for the creation of an application to be developed at NCL language to the Brazilian middleware Ginga [18], which can be used by Communities of Practice, exploring the new resources of Interactive Digital TV
Summary
The introduction of the Brazilian Interactive Digital Television model (iDTV) may lead to the development of several applications and services, exploiting its interactivity resources. This interactivity is the key competitive advantage in relation to the analog model. Several areas of human knowledge can benefit from the resources brought by iDTV, including Communities of Practice. Communities of Practice (CoP), according to Wenger, McDermott and Snyder [2], are groups of people who have common interests, problems to be solved or a passion for a subject and want to deepen their knowledge and experiences in these areas, interacting with each other regularly. Communities of Practice can be viewed as a subject that, in the last ten years, has attracted the interest of the academia mainly in engineering and knowledge management areas, due to its characteristics that allow its application in the organizational environment in activities of creation and knowledge management activities
