======NCL Resources======

[[http://www.ncl.org.br|Nested Context Language (NCL)]] is an XML-based declarative language to support the development of interactive multimedia presentations.
It is an [[http://en.wikipedia.org/wiki/SBTVD|ISDB-T International]] standard for Terrestrial Digital TV, and an [[http://www.itu.int/rec/T-REC-H.761|ITU-T recommendation for IPTV services]].

This page lists a number of resources supporting NCL.

===== Applications, Players and Plugins for NCL Viewing =====
Open Source Players:
  * [[http://github.com/telemidia/ginga|Ginga-NCL Reference Implementation]] is the ITU-T reference NCL player mainly developed by [[http://www.telemidia.puc-rio.br|TeleMidia Lab/PUC-Rio]].
