The document is divided in 3 separate parts that covers: SI for digital broadcasting systems (Part 1); Data structure and definition of SI basic Information (Part 2); and Syntax and definition of SI extended information (Part 3). The standard was written by telecommunications and television experts from many countries with their works coordinated by the SBTVD Forum and cover in detail all the aspects of video and audio coding that applies to SBTVD.

The multiplexing and SI standard is very similar to ARIB〔ARIB Association of Radio Industries and Businesses〕 equivalent keeping the data structure but with modified values for the parental control descriptor, genres and subgenres. The customized descriptor values reflect Brazilian laws, policies and culture. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「ABNT NBR 15603」の詳細全文を読む スポンサード リンク
