Abstract

"MéTODO PARA SINALIZAR A COMUTAçãO DE FLUXO ENTRE UMA PLURALIDADE DE FLUXOS DE BIT, DISPOSITIVO SERVIDOR STREAMING, SISTEMA STREAMING, E, PROGRAMA DE COMPUTADOR". Método de sinalização e dispositivo para usar na comutação de fluxo através da rede (60), na qual os pontos de acesso randómicos GDR são usados. Para indicar os pontos de comutação GDR nos fluxos de bit, a Caixa de Informação de Amostra de Sincronismo, que está contida na Caixa de Amostra de Sincronismo, é usada para prover a informação de tais pontos de comutação GDR. A informação também inclui um grupo de fatias que é a região isolada e um grupo de fatias que é a região restante, se os grupos de fatias forem aplicados na codificação. O método de sinalização pode ser usado na transmissão de vídeo usando o Protocolo de Transporte em Tempo Real (RTP, Real-time Transport Protocol) e, o Protocolo de Descrição de Sessão (SDP, Session Description Protocol) pode ser usado para carregar a informação indicativa das características dos fluxos de bit.
