Abstract

MÉTODO E DISPOSITIVO DE CODIFICAÇÃO DE IMAGEM/VÍDEO. Trata-se de um método de decodificação de vídeo realizado por um dispositivo de decodificação de vídeo de acordo com o presente documento que compreende as etapas de: adquirir informações de imagem a partir de um fluxo de bits, sendo que as informações de imagem incluem um cabeçalho de figuração associado à figuração atual incluindo uma pluralidade de fatias; analisar, a partir do cabeçalho de figuração, um primeiro sinalizador que indica se as informações necessárias para uma operação de interpredição para um processo de decodificação estão presentes no cabeçalho de figuração; analisar, a partir do cabeçalho de figuração, um segundo sinalizador que indica se as informações necessárias para uma operação de intrapredição para o processo de decodificação estão presentes no cabeçalho de figuração; e gerar amostras de predição realizando-se pelo menos uma dentre intrapredição ou interpredição para as fatias na figuração atual com base no primeiro sinalizador ou no segundo sinalizador.
