Ca_desc at ES stream level "wins" over ca_desc at program level (page 30 section 8.4.3.4 of EN50221): "If, for one elementary_stream, CA_descriptor(s) exist at programme level and at elementary_stream level, only the CA_descriptor(s) at elementary_stream level are taken into account." I think that the safest way would be to copy ca_desc from program level to each stream level except where ca_desc already exists for a stream. HTH
