A sincronização e a continuidade são essenciais para a apresentação multimídia, mas como os recursos da rede e a largura de banda disponível são limitados, a qualidade da sincronização e a qualidade da continuidade devem ser negociadas em resposta às condições flutuantes da rede. Este artigo, portanto, apresenta um algoritmo para sincronização intramídia com controle adaptativo de qualidade de serviço (QoS) tratado em diferentes camadas de fluxos multimídia. O trabalho aqui descrito é uma extensão de nossa proposta anterior de um algoritmo de sincronização por protocolo de compensação de atraso com dois mecanismos de ressincronização: ajuste de deslocamento de recuperação e salto de unidade de dados. Esse algoritmo foi estendido pela introdução de mecanismos de controle de QoS no plano de QoS de uma plataforma de controle distribuída. A abordagem estendida resulta não apenas em melhor sincronização e continuidade, mas também integra o ajuste de QoS na arquitetura existente. Variações inesperadas de QoS são enfrentadas por um controle de QoS adaptativo projetado para manter as qualidades de aplicação desejadas dentro do ambiente flutuante. Simulações implementadas em uma rede UDP/IP verificaram a eficácia do esquema proposto.

Abstract: Synchronization and continuity are essential for multimedia presentation, but because network resources and available bandwidth are both limited, synchronization quality and continuity quality have to be traded off in response to the fluctuating network conditions. This paper therefore introduces an algorithm for intramedia synchronization with adaptive quality of service (QoS) control handled at different layers of multimedia streams. The work described here is an extension of our earlier proposal of a synchronization algorithm by delay compensation protocol with two resynchronization mechanisms: retrieval offset adjustment and data unit skipping. That algorithm has been extended by the introduction of QoS control mechanisms in the QoS plane of a distributed control platform. The extended approach results not only in better synchronization and continuity, but also integrates the QoS adjustment into the existing architecture. Unexpected QoS variations are coped with by an adaptive QoS control designed to maintain the desired application qualities within the fluctuating environment. Simulations implemented on a UDP/IP network have verified the effectiveness of the proposed scheme.
