Abstract in Portuguese
Diversos sistemas computacionais transmitem informação em fluxos contínuos de dados estruturados e, por vezes, hierarquizados. Este modelo de transmissão de dados tem como uma de suas características a grande densidade de informação, o que exige de um receptor o tratamento imediato das unidades extraídas deste canal de comunicação. Muitas vezes o volume de transmissão não permite, também, que a informação recebida seja armazenada permanentemente no receptor, o que torna a análise do conteúdo desses fluxos de dados um desafio. Este trabalho apresenta uma arquitetura para a análise de fluxo de dados estruturados aplicado à hierarquia lógica definida pelo Sistema Brasileiro de TV Digital para a transmissão de programas de televisão, validada por meio de uma implementação de referência completamente funcional.

Abstract in English
Various computing systems transfer data in structured data streams which also happen to be, sometimes, hierarchically organized. Such data stream model is characterized by the dense amount of information transmitted, which requires the receiver to immediately manipulate the elements extracted from that communication channel. The high rate in which data flows also makes it hard, if not impossible, for the receiver to store the desired information in its memory, which makes data flow analysis especially challenging. This work presents a novel structured data flow analysis architecture applied to the logical hierarchy defined by the Brazilian Digital TV System for the transmission of television programs, validated by means of a fully functional reference implementation.
