Abstract

"PROCESSO PARA CODIFICAR UMA PLURALIDADE DE DADOS MULTIMìDIA, PRODUTO DE PROGRAMA DE COMPUTADOR PARA UM DISPOSITIVO DE CODIFICAçãO DE DADOS MULTIMìDIA, E, SINAL CODIFICADO TRANSMISSìVEL". A invenção refere-se a um processo para codificar uma pluralidade de dados multimídia de acordo com dados multimídia originais são adquiridos e convertidos em uma ou várias correntes de bits nas quais os diferentes níveis de informação são então capturados por intermédio de análise e segmentação. Uma etapa de descrição permite gerar a partir dos ditos níveis de informação obtidos dados de descrição que são então codificados. Mais exatamente, esta etapa de descrição compreende uma sub-etapa definidora, provida para armazenar um conjunto de descritores relacionados com a pluralidade de dados multimídia, e uma sub-etapa de descrição, provida para selecionar os dados de descrição a serem codificados de acordo com cada nível de informação conforme obtido na etapa de estruturação. O conjunto de descritores inclui, de acordo com a invenção, pelo menos um descritor de forma e um descritor de deformação de forma.
