Development of a GINGA-NCL receiver for Brazilian mobile broadcasting services

GINGA-Nested Context Language (GINGANCL) is a subsystem of GINGA, the standard for the Brazilian mobile broadcasting service, and it specifies the mechanisms and services used to enable various interactive data services. The integral part of GINGA-NCL is the NCL declarative language that provides non-invasive control of a multimedia presentation in time and space, as well as user interaction. In particular, one of its core competitive advantages over other existing technologies, such as Broadcast Markup Language (BML) and Open Mobile Alliance-Rich Media Environment (OMA-RME), is that it is substantially light-weight. Therefore, in this paper, we introduce an implementation of a GINGANCL receiver for mobile handsets. The proposed solution supports full feature GINGA-NCL sets, including XHTML and ECMAScript¹.
