Abstract

metodo e equipamento para melhorar o desempenho de rohc ao encontrar supressao de silencio são aqui descritos exemplos relacionados a métodos e sistemas para melhorar o desempenho de um compressor de compressão de header robusta (rohc) ao encontrar supressão de silêncio. em um exemplo, é calculado um incremento de marca de tempo (timestamp) rtp parapacotes sucessivos, até que um número predeterminado de pacotes possua um valor de incremento de marca de tempo constante, o valor de incremento de marca de tempo rtp constante é designado na forma de um valor de passo (stride) de marca de tempo (to_stride) para compressão, sendo o valor de cada marca de tempo (ts) rtp escalonado pelo passo de marca de rempo (ts_stride) e o header é comprimido usando-se o valor designado.
