 +===== EDTV/BDTV Profile Introduction =====
 +==== What is the NCL 3.0 EDTV/BDTV Profile? ====
 +EDTV is the acronym for Enhanced Digital TV.
 +The NCL 3.0 Enhanced DTV (EDTV) profile is the standard declarative language
 +of the Japanese-Brazilian DTV middleware ISDB-T<sub>B</sub> for fixed and
 +mobile receivers, and also ITU-T Recommendation for IPTV services.
 +BDTV is the acronym for Basic Digital TV.
 +The NCL 3.0 Basic DTV (BDTV) profile is a simplification of the EDTV profile
 +in which transition effects and metadata functionalities are optional.  This
 +profile is the standard declarative language of the Japanese-Brazilian DTV
 +middleware ISDB-T<sub>B</sub> for portable receivers.
 +The following processing instruction must be written in an NCL document in
 +conformance with these profiles.
 +<code xml>
 +<?xml version="1.0"?>
 +<ncl id="any string" xmlns="http://www.ncl.org.br/NCL3.0/profileName">
 +The //profileName//, in the URI path, identifies the language profile
 +used to specify the document and must be, in this case, //EDTVProfile//
 +or //BDTVProfile//, respectively.
 +Fourteen functionality areas with twenty nine modules are used to define the
 +Enhanced DTV and the Basic DTV profiles.  Attributes and contents (child
 +elements) of each element of a module may be defined in the module itself or
 +in the language profile that groups the modules.
 +In this handbook, each language element is presented in a specific section.
 +Each of these sections contains a one line element table in which element's
 +required attributes are underlined.  In these tables, the following symbols
 +are used: (?) optional (zero or one occurrences), (|) or, (*) zero or more
 +occurrences, (+) one or more occurrences.  The value of an attribute may not
 +contain quotation marks (<nowiki>"</nowiki>).  When a value is a string, it must
 +begin with a letter or an underscore and must contain only letters, digits,
 +<"."> and "_".
