| Lenguaje de contexto anidado (NCL) y Ginga-NCL |
La Recomendación UIT-T H.761 describe el lenguaje de contexto anidado (NCL) y un motor de presentación NCL llamado Ginga-NCL que aseguran el interfuncionamiento y la armonización entre marcos de aplicación multimedios TVIP. NCL es un lenguaje "pegamento" que aglutina objetos de medios en presentaciones multimedios, independientemente del tipo de objetos de que se trate. A título de ejemplo, NCL trata un documento HTML como uno de sus posibles objetos de medios. De esta manera, NCL no sustituye sino que integra documentos con XHTML. El mismo razonamiento se aplica a otros objetos con contenido medios y multimedios, y también a objetos con contenido codificado en cualquier lenguaje informático. Ginga-NCL es un motor de presentación NCL creado como un componente de programa intermedio (middleware) TVD. NCLua, un objeto de medios obligatorio con código Lua, es un tipo de objeto NCL muy especial definido en Ginga-NCL. Esta Recomendación incluye un fichero electrónico que contiene esquemas de módulos NCL 3.0 utilizados en el perfil TVD mejorado. |
