int InterpretPPS ( DataPartition *  p,
pic_parameter_set_rbsp_t *  pps 
)

Note: as per JVT-F078 the following bit is unconditional. If F078 is not accepted, then one has to fetch the correct SPS to check whether the bit is present (hopefully there is no consistency problem :-( The current encoder code handles this in the same way. When you change this, don't forget the encoder! StW, 12/8/02
