Abstract
A method of encoding an image of a video sequence, the image being represented by a plurality of coding units, the encoding comprising at least two different encoding processes for encoding the image wherein each encoding process introduces coding dependencies between coding units, the method comprising: determining a set of slice boundaries for each encoding process wherein the set of slice boundaries for each encoding process partitions the image into one or more slices for the respective encoding process, the one or more slices each including a set of coding units of the image between a pair of respective slice boundaries; the coding units of one slice being encoded independently of coding units of another of the slices of the respective encoding process; wherein the slice boundaries for each encoding process are defined as a function of at least one slice boundary defining parameter.
