摘要

Methods and systems for decoding a picture. A method includes receiving a coded video stream including a picture partitioned into first sub-picture units, the first sub-picture units including one first sub-picture unit, and an additional first sub-picture unit including a first ordered second sub-picture unit, from among second sub-picture units of the additional first sub-picture unit, and a last ordered second sub-picture unit, from among the second sub-picture units of the additional first sub-picture unit. The method further including decoding the picture, the decoding including obtaining index values of the first ordered second sub-picture unit and the last ordered second sub-picture unit of the additional first sub-picture unit, without the coded video stream explicitly signaling any of the index values and a difference value between the index values of the first ordered second sub-picture unit and the last ordered second sub-picture unit to the at least one processor.

The computer software can be coded using any suitable machine code or computer language, that may be subject to assembly, compilation, linking, or like mechanisms to create code comprising instructions that can be executed directly, or through interpretation, micro-code execution, and the like, by computer central processing units (CPUs), Graphics Processing Units (GPUs), and the like.

The instructions can be executed on various types of computers or components thereof, including, for example, personal computers, tablet computers, servers, smartphones, gaming devices, internet of things devices, and the like.

The components shown in FIG. 9 for computer system 900 are exemplary in nature and are not intended to suggest any limitation as to the scope of use or functionality of the computer software implementing embodiments of the present disclosure. Neither should the configuration of components be interpreted as having any dependency or requirement relating to any one or combination of components illustrated in the non-limiting embodiment of a computer system 900.

Computer system 900 may include certain human interface input devices. Such a human interface input device may be responsive to input by one or more human users through, for example, tactile input (such as: keystrokes, swipes, data glove movements), audio input (such as: voice, clapping), visual input (such as: gestures), olfactory input (not depicted). The human interface devices can also be used to capture certain media not necessarily directly related to conscious input by a human, such as audio (such as: speech, music, ambient sound), images (such as: scanned images, photographic images obtain from a still image camera), video (such as two-dimensional video, three-dimensional video including stereoscopic video).
