Abstract
"PROCESSO E APARELHO PARA EXECUTAR LIMPEZAS EM FLUXOS DE BITS DE VìDEO MPEG COMPRIMIDOS" trata-se de um método e aparelho para produzir uma seq³ência de limpeza em um dispositivo de exibição a partir dos fluxos de bits de vídeo compactados que chegam que realiza o processamento da função de limpeza totalmente no domínio compactado dos fluxos de bits de vídeo compactados. Os fluxos de bits ou seq³ências vídeo antigos e novos separadamente suportam uma convolução bidimensional entre seus coeficientes DCT codificados e coeficientes DCT armazenados de uma função de limpeza conhecida particular. Cada fluxo de bits convolucionado é colocado em buffer com sua escala de quantização e então somados um com o outro. Os fluxos de bits de saída somados são utilizados por um multiplexador junto com cada dado de macrobloco decodificado do fluxo de bits para proporcionar um fluxo de bits de saída unido. Um controlador controla o processo tal como a correlação de quadro para a convolução e a multiplexação de saída dos fluxos de bits somados.
