Abstract: A dependency indication is included at the beginning of a packet, i.e., in the vicinity of an analysis target slice header or parameter set, and is delivered by a signal. This is achieved, for example, by including the dependency indication at the beginning of the slice header, ideally after a syntax element identifying the parameter set, and before the slice address, by using a separate message and providing the dependency indication to an NALU header, or by using a special NALU type used in an NALU holding a dependent slice.

Abstract: La presente invención se refiere a un método de decodificación de imágenes para decodificar una corriente de bits que incluye una señal codificada que resulta de la codificación de cortes en los cuales se divide una imagen y cada uno de los cuales incluye unidades de codificación, incluye decodificar la señal codificada, en donde cada uno de los cortes es ya sea un corte normal que tiene, en un encabezado de corte, información utilizada para otro corte o un corte dependiente el cual se decodifica utilizando información incluida en un encabezado de corte de otro corte, la imagen incluye hileras cada una de las cuales incluye unidades de codificación y cuando el corte normal inicia en una posición diferente del comienzo de la primera hilera, la segunda hilera inmediatamente después de la primera hilera no inicia con el corte dependiente.

Abstract: An image decoding method capable of reducing processing load includes: obtaining a boundary control flag for jointly controlling a deblocking filter operation and a sample adaptive offset operation for a slice boundary of a current slice to be decoded included in a coded picture (S11); decoding the current slice (S12); performing the deblocking filter operation based on the boundary control flag only on at least one of a top slice boundary or a left slice boundary among all slice boundaries of the current slice that has been decoded (S13); and performing the sample adaptive offset operation dependent on the boundary control flag only on the at least one of the top slice boundary or the left slice boundary among all the slice boundaries of the current slice that has been decoded (S14).

Abstract: The present invention relates to deblocking filtering, which may be advantageously applied for block-wise encoding and decoding of images or video signals. In particular, the present invention relates to an improved memory management in an automated decision on whether to apply or skip deblocking filtering for a block and to selection of the deblocking filter. The decision is performed on the basis of a segmentation of blocks in such a manner that memory usage is optimized. Preferably, the selection of appropriate deblocking filters is improved so as to reduce computational expense. Figure 19.

Abstract: AN IMAGE PROCESSING METHOD OF PERFORMING FILTERING ON IMAGE BLOCKS USING A PLURALITY OF DEBLOCKING FILTERS HAVING DIFFERENT FILTER STRENGTHS INCLUDES: A FIRST PARAMETER CALCULATING STEP OF CALCULATING A FIRST PARAMETER (BS) INDICATING A BOUNDARY STRENGTH; A SECOND PARAMETER CALCULATING STEP OF CALCULATING A SECOND PARAMETER (TC) INDICATING A LIMIT VALUE FOR EACH OF THE DEBLOCKING FILTERS, BASED ON THE FIRST PARAMETER (BS) AND A QUANTIZATION PARAMETER (QP); AND A SELECTING STEP OF SELECTING A DEBLOCKING FILTER TO BE USED IN THE FILTERING FROM AMONG THE DEBLOCKING FILTERS, USING ONE OR MORE THRESHOLD VALUES WHICH ARE DETERMINED BASED ON THE SECOND PARAMETER (TC).
