摘要： During a coding process, systems, methods, and apparatus may code data representative of the positions of elements of a chain that partitions a prediction unit of video data. Some examples may include generating the data representative of the positions of elements of a chain that partitions a prediction unit of video data. Each of the positions of the elements except for a last element may be within the prediction unit. The position of the last element may be outside the prediction unit. This can indicate that the penultimate element is the last element of the chain. Some examples may code the partitions of the prediction unit based on the chain.
