Claim:
1. A method for decoding a video bitstream comprising: (a) receiving a first bitstream layer representative of a coded video sequence; (b) receiving a second bitstream layer representative of said coded video sequence; (c) receiving a first dimension syntax element value associated with said first bitstream layer included within a first set of syntax elements defining a maximum width in luma samples of all pictures in said first bitstream layer; (d) receiving a second dimension syntax element value associated with a first picture within said first bitstream layer included within said first set of syntax elements defining the width of said first picture in luma samples; (e) receiving a third dimension syntax element value associated with a second picture within said first bitstream layer included within said first set of syntax elements defining the width of said second picture in luma samples; (f) receiving a fourth dimension syntax element value associated with said first bitstream layer included within said first set of syntax elements defining a maximum height in luma samples of all pictures in said first bitstream layer; (g) receiving a fifth dimension syntax element value associated with said first picture within said first bitstream layer included within said first set of syntax elements defining the height of said first picture in luma samples; (h) receiving a sixth dimension syntax element value associated with said second picture within said first bitstream layer included within said first set of syntax elements defining the height of said second picture in luma samples; (i) decoding said first picture based upon said second dimension syntax element value and said fifth dimension syntax element value, decoding said second picture based upon said third dimension syntax element value and said sixth dimension syntax element value, where said second dimension syntax element value is less than said first dimension syntax element value, where said third dimension syntax element value is less than said first dimension syntax element value, where said second dimension syntax element value has a different value than said third dimension syntax element value, where said fifth dimension syntax element value is less than said fourth dimension syntax element value, where said sixth dimension syntax element value is less than said fourth dimension syntax element value, where said fifth dimension syntax element value has a different value than said sixth dimension syntax element value.
