An example video coding system may include a processor and memory. The processor may determine sets of parameters for slices that correspond to a picture of a video sequence, and determine, and store in overhead information, the set of parameters that has the highest commonality. The processor may determine for each slice whether the set of parameters determined for the slice is equivalent to the set of parameters stored in overhead information. If the set of parameters for the slice is equivalent to the set of parameters stored in overhead information, the processor may store an indication in a slice header of the slice that indicates that the set of parameters stored in overhead information applies to the slice, otherwise the processor may store in the slice header of the slice the determined set of parameters for the slice. The processor may transmit the overhead information and the slices.
