Abstract

resumo “sinalização de modo de intra-predição melhorada para codificação de vídeo utilizando modo de vizinhos”. essa descrição descreve técnicas para sinalização de modo de intra-predição para a codificação de vídeo. em 5 um exemplo, um codificador de vídeo é configurado para determinar, para um bloco de dados de vídeo, um conjunto de modos de intra-predição mais prováveis de modo que o conjunto de modos de intra-predição mais prováveis tenha um tamanho que é igual a um número predeterminado que é maior 10 do que ou igual a dois. o codificador de vídeo também é configurado para codificar um valor representativo de um modo de intra-predição atual para o bloco com base pelo menos em parte no conjunto de modos de intra-predição mais prováveis e codificar o bloco utilizando o modo de intra-15 predição atual. o codificador de vídeo pode ser adicionalmente configurado para codificar o bloco utilizando o modo de intra-predição atual, por exemplo, para codificar ou decodificar o bloco. os codificadores de vídeo e decodificadores de vídeo podem implementar essas 20 técnicas.
