Abstract

SISTEMAS E MÉTODOS PARA CRIPTAÇÃO DE BAIXA COMPLEXIDADE E DETECÇÃO EM PLANO DE FUNDO. Trata-se de sistemas e métodos para criptação de baixa complexidade e detecção em plano de fundo. Um aspecto do assunto descrito na revelação fornece um criptador de vídeo que compreende uma memória configurada para armazenar um bloco de vídeo. O criptador de vídeo compreende adicionalmente um processador em comunicação com a memória. O processador é configurado para determinar se o bloco de vídeo está em plano de fundo através da comparação do bloco de vídeo com um bloco correspondente localizado em um quadro temporal anterior. O processador é adicionalmente configurado para determinar, quando o bloco de vídeo não está em plano de fundo, se um ou mais sub-blocos do bloco de vídeo estão em plano de fundo através da comparação dos sub-blocos com sub-blocos correspondentes localizados no quadro temporal anterior.
