Syntax and definition of SI extended information.
The multiplexing and SI standard is very similar to ARIB  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. This standard specifies the basic configuration of service information used in digital broadcasting, detailed data structures of this service information, and operational guidelines.
Service information consists of signals that complement the transmission control signals and program specific information as defined in MPEG-2 systems. It is provided to convey multiplexed program data to a receiver and to simplify program selection. The multiplexed-signal formats PES packet, section format, TS packet, composition of the transmission control signal, composition of descriptors, composition of identifiers, and composition of related information are thoroughly listed.
The specification is intended to allow a wide range of applications and to integrate detailed data structures and usage guidelines with the basic configuration. The service information was specified under the preconditions of international compatibility in data structures, ngr in accommodating various program configurations from different broadcasters, and extendibility with respect to future broadcast services.
The multiplexing and SI standard is very similar to ARIB equivalent keeping the data structure but with modified values for the parental control descriptor, genres and subgenres.
These documents are also officially available at ABNT website.
The multiplexing and SI requirements established for the Brazilian digital television standards make use of the same fundamental systems that also exist in the Japanese digital television standards as can be seen on ARIB STD-B The three volumes of the multiplexing and SI standards are described in detail in documents: From Wikipedia, the free encyclopedia.
