1. A video streaming device, comprising:
a communication interface; and
a memory coupled to the communication interface,
wherein the communication interface is configured to receive or transmit a video bitstream and the memory is configured to store the video bitstream,
wherein the video bitstream comprises data representing an image region, an image region header of the image region, a parameter set, and an override enabled flag, wherein the override enabled flag indicates whether partitioning a block of the image region according to first partition constraint information is enabled, wherein the first partition constraint information is comprised in the image region header, wherein the image region header is a picture header,
wherein on condition that a value of the override enabled flag is an enabling value, the video bitstream further comprises an override flag, and wherein the override flag indicates whether the first partition constraint information from the image region header or second partition constraint information from the parameter set is to be used for partitioning the block.
