摘要：A slice flag associated with a slice in the picture is retrieved from the coded picture representation. The value of this slice flag is employed in order to determine whether a slice address needs to be retrieved from the coded picture representation in order to identify the start position of the slice within the picture and the portion of the slice that belongs to the slice. If the slice flag has a first defined value, the present slice is the first slice in the picture. Pixel values of pixels in the slice generated by decoding a coded slice representation associated with the slice and retrieved from the coded picture representation are then assigned to a first portion of the picture starting with a defined slice start within the picture, such as top left corner. If the slice flag instead has a second defined value, the slice address is employed to identify the slice start within the picture and pixel values generated by decoding the coded slice representation of the pixel are assigned to the portion of the picture starting with the identified slice start.
