Abstract
MÉTODO E APARELHO DE CODIFICAÇÃO DE IMAGEM/VÍDEO BASEADOS EM TABELA PONDERADA DE PREDIÇÃO. Trata-se de um método de decodificação de vídeo executado por um aparelho de decodificação de vídeo de acordo com o presente documento que compreende as etapas de: analisar um sinalizador associado à predição ponderada a partir de um fluxo de bits; com base no sinalizador, analisar uma sintaxe de tabela ponderada de predição a partir do fluxo de bits; e com base na sintaxe de tabela ponderada de predição, executar uma predição ponderada em um bloco atual em uma figuração atual para reconstruir a figuração atual, em que com base no valor do sinalizador sendo 1, a sintaxe de tabela ponderada de predição pode ser analisada a partir de um cabeçalho de figuração do fluxo de bits, e com base no valor do sinalizador sendo 0, a sintaxe de tabela ponderada de predição pode ser analisada a partir de um cabeçalho de fatia do fluxo de bits.
