Claim 0:
1. A method for decoding a picture from a bitstream, the method comprising:
decoding a segment partitioning structure from one or more syntax elements in the bitstream;
decoding a number, M, from a syntax element in a parameter set, wherein M represents the number of segment groups there are in the picture, and wherein each segment group consists of an integer number of segments;
decoding, in a loop executing once for each partition of the segment partitioning structure, wherein the segment partitioning structure defines at least two partitions of the picture, one or more dependency syntax elements from a parameter set in the bitstream, the one or more dependency syntax elements describing dependencies between the at least two partitions, wherein a partition is a segment group and the loop executes M times;
deriving the dependencies between the at least two partitions using the one or more decoded dependency syntax elements; and
using the derived dependencies to decode the picture.
