Abstract
MÉTODO E APARELHO PARA CODIFICAÇÃO MODO INTRA EM HEVC. São descritos um método e um aparelho para a codificação ou decodificação de modo de predição Intra com base em modos multi-nível (MPMs)mais prováveis. Em uma realização de acordo com a presente invenção, o método e o aparelho para a codificação ou decodificação do modo de predição Intra para unidades de predição 4X4 (PU) utiliza 19 amostras modo Intra para obter cobertura direcional completa ou 35 amostras modo Intra tal como utilizados por PU'S de 8X8, 16x16 e 32x32. Em outra realização da presente invenção, três MPMS são utilizados para codificar os modos Intra. Vários métodos para derivar os três MPMS com base nos modos Intra de blocos vizinhos são descritos. Em ainda outra outra realização da presente invenção, o método de codificação para os rnodos restantes compreende codificação de comprimento fixo. Em adição, é também descrita a codificação de comprimento variável para os modos restantes.
