Abstract

CONTENÇÕES DE CONJUNTO DE PARÂMETROS DE VÍDEO PARA EXTRAÇÃO DE SUB-BITSTREAM DE SUBIMAGEM. Um método de processamento de dados de vídeo inclui desempenhar uma conversão entre um vídeo e um bitstream do vídeo. O bitstream compreende uma ou mais camadas compreendendo uma ou mais subcamadas compreendendo uma ou mais imagens compreendendo uma ou mais subimagens de acordo com uma regra que especifica uma operação de reescrita desempenhada seletivamente em uma ou mais estruturas de sintaxe durante um processo de extração de sub-bitstream de subimagem pelo qual um sub-bitstream de destino de saída é extraído a partir do bitstream. O um ou mais elementos de sintaxe incluem informações do sub-bitstream de destino de saída.
