Abstract

MéTODO DE CODIFICAçãO DE DADOS DE MULTIMìDIA E DISPOSITIVO DE CODIFICAçãO Um método de codificação para transcepção sem fio para dado de multimídia incluindo dado de vídeo, e um dispositivo de codificação são, portanto, fornecidos. O método de codificação inclui (a) geração de um campo de extensão representando o número de bits de uma carga de pagamento, (b) geração de um código de correção de erro através da execução de codificação de correção de erro com respeito ao campo de extensão, e (c) introdução do campo de extensão e código de correção de erro durante a estruturação de protocolo de ligação a rádio (RLP). O método de codificação reduz o desalinhamento quando o dado de multimídia incluindo dado de vídeo é transmitido e recebido sob o ambiente por rádio, e aumenta a robustez do erro, melhorando assim a qualidade de uma imagem.
