Abstract

"MéTODO E EQUIPAMENTO PARA REDUZIR DISTORçãO DE AAL5", para um sistema de transmissão de dados de imagem para converter dados MPEG em células ATM e transmitir as células ATM através de uma linha ATM, um valor médio de adição dos relógios de tempo do sistema em cronometragens para detectar inícios de pacotes de transporte adjacentes após o término da AAL5 ser obtido. Um tempo de chegada de pacote de transporte é corrigido com base no valor médio de adição obtido. Um equipamento de redução de distorção de AAL5 é também apresentado.
