Abstract
"AJUSTE DE QUALIDADE DINâMICO BASEADO NA MUDANçA DE RESTRIçõES DE FLUXO". Trata-se de um método e aparelho para ajuste de qualidade dinâmico de mídia digital com base na mudança de restrições de fluxo. Um servidor de mídia digital envia um fluxo de mídia digital de acordo com um conjunto de restrições de fluxo para um cliente solicitante. Um cliente envia uma solicitação (400) em uma rede de controle para o servidor de mídia digital indicando que informações de um tipo particular não são mais desejadas. Em resposta a receber o sinal, o servidor de vídeo cessa a transmissão daquele tipo particular de informações 9430) para o cliente que sinaliza, relaxando assim as restrições de fluxo (440), quando um espectador sinaliza que um tipo particular de informação não e desejada, aquele tipo particular de informação não é transmitida para o cliente, o que reduz as restrições de fluxo em um serviço de fluxo de vídeo e informações de mídia digital com maior qualidade (450) podem ser enviadas para qualquer cliente que utilize a parte liberada da largura de banda alocada anteriormente para o cliente que sinalizou.
