Abstract

um método de processamento de vídeo inclui: a recepção de uma imagem/conteúdo de vídeo omnidirecional correspondendo a uma esfera de visualização, geração de uma sequência de quadros baseados em projeção de acordo com a imagem/conteúdo de vídeo omnidirecional e um layout de projeção em cubo baseada em janela de exibição, e codificação da sequência de quadros baseados em projeção para gerar um fluxo de bits. cada quadro baseado em projeção contém uma imagem/conteúdo de vídeo de 360 graus representado por faces de projeção retangular empacotadas no layout de projeção em cubo baseada em janela de exibição. as faces de projeção retangular incluem uma primeira face de projeção retangular, uma segunda face de projeção retangular, uma terceira face de projeção retangular, uma quarta face de projeção retangular, uma quinta face de projeção retangular, e uma sexta face de projeção retangular dividida em faces de projeção retangular parciais. a primeira face de projeção retangular corresponde à janela de exibição do usuário, e é fechada por uma área circundante composta da segunda face de projeção retangular, da terceira face de projeção retangular, da quarta face de projeção retangular, da quinta face de projeção retangular, e das faces de projeção retangular parciais.
