Abstract: 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.

Abstract: For each respective coding unit (CU) of a slice of a picture of the video data, a video coder may set, in response to determining that the respective CU is the first CU of a coding tree block (CTB) row of the picture or the respective CU is the first CU of the slice, a derived disparity vector (DDV) to an initial value. Furthermore, the video coder may perform a neighbor-based disparity vector derivation (NBDV) process that attempts to determine a disparity vector for the respective CU. When performing the NBDV process does not identify an available disparity vector for the respective CU, the video coder may determine that the disparity vector for the respective CU is equal to the DDV.
