Claim:
1. A method for encoding a video bitstream, the method comprising: partitioning a picture in the video bitstream into a first portion and a second portion; generating a first slice header corresponding to the first portion of the picture in the video bitstream; generating a second slice header corresponding to the second portion of the picture in the video bitstream, wherein the second slice header is different than the first slice header and shares some slice attributes with the first slice header, and wherein the size of the second slice header is smaller than the size of the first slice header; setting a value of a flag corresponding to the first slice header to a first value to indicate that the first slice header is a regular slice header; setting a value of a flag corresponding to the second slice header to a second value to indicate that the second slice header is a partitioned slice header; encoding the first portion of the picture in the video bitstream to generate the first coded data using the first slice header; encoding the second portion of the picture in the video bitstream to generate the second coded data using the first portion of the picture, the first slice header and the second slice header; and entropy coding the first slice header, the second slice header, the first coded data, and the second coded data, wherein encoding the first portion of the picture comprises transforming a residual block in the first portion of the picture, and wherein the first value of the flag corresponding to the first slice header is 0.
