"A slice is a series of macroblocks, all placed within the same row horizontally. Slices are not allowed to overlap. The division of slices may vary from picture to picture. If &quot;restricted slice structure&quot; is applied, the slices must cover the whole pictures. If &quot;restricted slice structure&quot; is not applied, the decoder will have to decide what to do with that part of the picture, which is not covered by a slice. Motion vectors are not allowed to point at the part of the picture, which is not covered by a slice. Note that main profile utilizes &quot;restricted slice structure,&quot; that is, all the slices put together must cover the picture."
