A CPI_type is stated in the PlayList( ) The CPI Type comprises a EP_type and a EP_map type. If the position of an I-picture can be known by analysis, EP_type is used, whereas, if the position of an I-picture cannot be known by analysis, EP_map type is used. Therefore, AV stream data recorded subject to analysis of the I-picture and AV stream data recorded without analyzing the I-picture position can be supervised in common.
