Abstract

MUDANÇA DE CANAL RÁPIDA Em uma implementação de servidor exemplar, um servidor é configurado para reter pelo menos um quadro independente para cada canal de vídeo de múltiplos canais de vídeo que estão sendo distribuídos usando comunicações de multidifusão e que é adaptado para responder a solicitações de mudança de canal de clientes transmitindo o pelo menos um quadro independente retido de um canal de vídeo solicitado a um cliente solicitante usando uma comunicação ponto-a-ponto. Em uma implementação do método exemplar, um método para mudança de canal rápida em uma arquitetura de distribuição de vídeo de comunicação de multidifusão inclui: detectar uma solicitação de mudança de canal que indique um canal solicitado, o canal solicitado correspondente a um grupo de comunicação de multidifusão; e transmitir um intraquadro retido para o canal solicitado como uma comunicação ponto-a-ponto.
