Abstract

"MéTODO E APARELHO DE CODIFICAçãO E DECODIFICAçãO, APARELHO DE COMUNICAçãO SEM FIO COM CODIFICADOR INCORPORADO, E, CODEC DE VìDEO". O método de codificação de vídeo compreende: o recebimento do sinal a ser codificado; a codificação dos dados representando o quadro do sinal de vídeo; repetir uma parte, mas não todos os dados, a parte repetida incluindo o cabeçalho da imagem para o quadro. O método de decodificação do sinal de vídeo codificado, o método compreendendo o recebimento dos dados codificados representando os quadros do sinal de vídeo; examinar os dados codificados para detectar os dados do cabeçalho e os dados da imagem; quando um erro no cabeçalho da imagem for detectado, armazenar os dados da imagem no armazenador de dados de imagem temporário, detectar uma repetição dos dados do cabeçalho; e decodificar os dados de imagem armazenados usando os dados repetidos do cabeçalho.
