Abstract

resumo "codificação de valores de contagem de ordem de imagem identificando quadros de referência de longo termo". em geral, técnicas são descritas para codificação de valores de contagem de ordem de imagem identificando imagens de referência de longo termo. um dispositivo de decodificação de vídeo compreendendo um processador pode realizar as técnicas. o processador pode determinar os bits menos significativos (lsbs) de um valor de contagem de ordem de imagem (poc) que identifica uma imagem de referência de longo termo (ltrp). os lsbs não identificam de forma singular o valor poc com relação aos lsbs de qualquer outro valor poc identificando qualquer outra imagem em um armazenador de imagem decodificada (dpb). o processador pode determinar os bits mais significativos (msbs) do valor poc. os msbs combinados com os lsbs são suficientes para distinguir o valor poc de qualquer outro valor poc que identifique qualquer outra imagem no dpb. o processador pode recuperar a ltrp do armazenador de imagem decodificada com base nos lsbs e msbs do valor poc, e decodificar uma imagem atual dos dados de vídeo utilizando a ltrp recuperada. 1/1
