Document technical overview

The Brazilian technical standard for digital television concerns specifications of receivers for digital broadcasting, and specifies, in particular, minimum basic functions and essential requirements to satisfy initial needs for the deployment of digital terrestrial television broadcasting. The standard does not cover features which affect the quality of the displayed picture or application rather than whether receiver is able to decode pictures at all. Such issues are left to the marketplace. Wherever practical the Brazilian standard suggests implementations that ignore reserved and private information and allows for future compatible extensions to the bit-stream. In order to maintain user habit, Brazilians have defined a code to keep, in the digital format, the same channel numbers used in analogue broadcasting, thus making it possible to have an analogue to digital transition with maximum transparency. The code is called virtual channel numbering. These documents are also officially available at ABNT website.

Summary

The requirements established for receivers in the Brazilian digital television standard allow for a variety of receiver models with many possible combinations of optional features, while maintaining the basic common required features expected for high quality of service. The ABNT NBR 15604:2007 - Digital terrestrial television – Receivers describes in detail the required and optional features for the system on the receiver side.
