1. A method for decoding at least one current picture from a bitstream, the method comprising:
decoding an indicator value from the bitstream specifying at least one rule of a plurality of rules, the at least one rule applied to ordering of segments coded in the bitstream and provides a plurality of allowed segment orders for decoding the at least one current picture from the bitstream, wherein the segments are segments in a segment partition layout;
decoding a set of syntax elements from the bitstream specifying a segment partition layout;
deriving a segment partition layout based on the set of syntax elements; and
decoding the at least one current picture in the bitstream using the segment partition layout, wherein the ordering of the segments corresponds to one of the plurality of segment orders allowed by the at least one rule specified.
