Abstract

"FORMATO DE CARGA úTIL RTP". Trata-se de um fluxo de dados que é criptografado para formar unidades de criptografia que são transformadas em pacote em pacotes RTP. Cada pacote RTP inclui um cabeçalho de pacote RTP, uma ou mais cargas úteis de um fluxo de dados comum e um cabeçalho de formato de carga útil RTP para cada carga útil e incluindo, para as unidades de criptografia correspondentes, um limite para a carga útil. A carga útil pode ser uma ou mais das unidades de criptografia ou um fragmento de uma das unidades de criptografia. As unidades de criptografia são montadas novamente utilizando as cargas úteis nos pacotes RTP e os limites respectivos no cabeçalho de formato de carga útil RTP respectivo. As unidades remontadas de criptografia são decriptografadas para sintetização. Cada cabeçalho de formato de carga útil RTP pode possuir atributos para a carga útil correspondente que pode ser utilizada para sintetizar a carga útil. Os pacotes RTP podem ser enviados servidor-para-cliente ou de forma não hierárquica.
