Since hybrid applications are common, either type of Ginga application may make use of facilities of both presentation and execution application environments. This paper focuses on the presentation environment Ginga-NCL. The main Brazilian inovations are then presented, regarding the Ginga architecture, the declarative NCL language specification, the editing commands for live application production, and the transport data structure.<\/jats:p>","DOI":"10.1007\/bf03192400","type":"journal-article","created":{"date-parts":[[2010,11,11]],"date-time":"2010-11-11T15:20:14Z","timestamp":1289488814000},"page":"37-46","source":"Crossref","is-referenced-by-count":50,"title":["Ginga-NCL: the declarative environment of the Brazilian digital TV System"],"prefix":"10.1007","volume":"13","author":[{"given":"Luiz Fernando Gomes","family":"Soares","sequence":"first","affiliation":[]},{"given":"Rog\u00e9rio Ferreira","family":"Rodrigues","sequence":"additional","affiliation":[]},{"given":"M\u00e1rcio Ferreira","family":"Moreno","sequence":"additional","affiliation":[]}],"member":"297","reference":[{"key":"BF03192400_CR1","unstructured":"Advanced Application Platform (ACAP),ATSC Standard: Document A\/101, August 2005."},{"key":"BF03192400_CR2","unstructured":"ARIB B-24 XML-based Multimedia Coding Scheme,ARIB Standard B-24 Data Coding and Transmission Specifications for Digital Broadcasting, version 4.0, February 2004."},{"key":"BF03192400_CR3","unstructured":"P.
