Abstract

um dispositivo de cliente exemplar inclui uma unidade de middleware para receber dados de mídia, seja por meio de um serviço de broadcast ou de um serviço de unicast, dependendo de se o serviço de broadcast está disponível. o dispositivo de cliente também inclui um cliente de streaming, como um cliente de streaming adaptativo dinâmico sobre http (dash). o dash cliente envia solicitações para recuperar dados de mídia através da unidade de middleware. a unidade de middleware pode armazenar em cache dados de mídia recebidos através do serviço de broadcast, de modo que, mesmo quando o serviço de broadcast não está ativo, se o cliente de streaming solicita dados de mídia que foram recebidos anteriormente através do serviço de broadcast, a unidade de middleware pode prover os dados de mídia para o cliente de streaming a partir do cache, em vez de solicitar os dados de mídia de um dispositivo de servidor externo especificado na solicitação do cliente de streaming.
