Abstract: An image coding method according to an aspect of the present invention includes: writing, into a sequence parameter set, buffer description defining information for defining a plurality of buffer descriptions (S102); selecting one of the buffer descriptions for each processing unit that is a picture or a slice, and writing buffer description selecting information for specifying the selected buffer description, into a first header of the processing unit which is included in the coded bitstream (S103 and S104); and coding the processing unit using the selected buffer description (S105), and the buffer description defining information includes long-term information for identifying, among a plurality of reference pictures covered by the buffer descriptions, a reference picture to be assigned as a long-term reference picture.

Abstract: O método de decodificação de imagem inclui: determinação de um contexto para uso em um bloco atual, de entre uma pluralidade de contextos (S204); e realização de decodificação aritmética em uma sequência de bit correspondente ao bloco atual, usando o contexto determinado (S210), no qual na determinação (S204): o contexto é determinado sob uma condição que parâmetros de controle de blocos vizinhos do bloco atual são usados, quando o tipo de sinal é um primeiro tipo, os blocos vizinhos sendo um bloco esquerdo e um bloco superior do bloco atual (S206); e o contexto é determinado sob uma condição que o parâmetro de controle do bloco superior não é usado, quando o tipo de sinal é um segundo tipo (S207), e o segundo tipo é "no_residual_data_flag".

Abstract: The image decoding method includes determining a context for use in a current block, from among a plurality of contexts (S204), wherein in the determining (S204): the context is determined under a condition that the control parameter of the upper block is not used, when the signal type is a second type (S207), and the second type is (i) "merge_flag", (ii) "ref_idx_l0" or "ref_idx_l1", (iii) "inter_pred_flag", (iv) "mvd_l0" or "mvd_l1", (v) "no_residual_data_flag", (vi) "intra_chroma_pred_mode", (vii) "cbf_luma", and (viii) "cbf_cb" or "cbf_cr".

Abstract: Bir bit akışının oluşturulması amacıyla, bir blok blok bazında bir resmi kodlamak için bir görüntü kodlama metodu olup, aşağıdakileri içerir: bir birinci birleştirme adayı olarak, bir öngörü yönü, bir hareket vektörü ve mevcut bloğun kodlanmasında kullanılmak üzere bir referans resim indeksinin bir birleşiminden oluşan bir birleştirme adayının türetilmesi (S201); ikinci bir birleştirme adayı olarak, önceden belirlenmiş bir vektör olan bir hareket vektörüne sahip olan bir birleştirme adayının türetilmesi (S202); mevcut bloğun türetilmiş birinci birleştirme adayından ve türetilmiş ikinci birleştirme adayından kodlanması için kullanılacak bir birleştirme adayının seçilmesi (S203); ve seçilen birleştirme adayının bit akışına tanımlanması için bir indeks eklenmesi (S204).

Abstract: An image decoding method of decoding, on a block-by-block basis, image data included in a coded stream includes: deriving candidates for an intra prediction mode to be used for intra prediction for a decoding target block, the number of the candidates constantly being a plural number; obtaining, from the coded stream, an index for identifying one of the derived candidates for the intra prediction mode; and determining, based on the obtained index, one of the derived candidates for the intra prediction mode as the intra prediction mode to be used for intra prediction for the decoding target block.
