Ginga (middleware)


Ginga is the middleware specification for the Nipo-Brazilian Digital TV System. Ginga is also ITU-T Recommendation for IPTV Services. It is also considered in ITU-T recommendations for Cable Broadcast services and for Terrestrial Broadcast services by ITU-R BT.1889, ITU-R BT.1699 and ITU-R BT.1722. Ginga was developed based on a set of standardized technologies but mainly on innovations developed by Brazilian researchers. Its current reference implementation was released under the GPL license.
Ginga is divided into two main integrated subsystems, which allow the development of applications following two different programming paradigms. Those subsystems are called Ginga-NCL and Ginga-J.
In the case of the Brazilian Terrestrial Digital TV System, and any other Digital TV Systems following the definitions in the ABNT standards for the Ginga Middleware ABNT 15606, Ginga-J is required to be supported in fixed receivers and it is optional in portable receivers. For IPTV services following the H.761 ITU-T Recommendation, only the Ginga-NCL subsystem is required, for any terminal type.

Development

Ginga was developed by Telemídia Lab from Pontifical Catholic University of Rio de Janeiro and by LAViD from Federal University of Paraíba.
