Abstract
In a DVD recording/playback system, a set top box STB receives an MPEG transport stream constituted by a plurality of transport packets, and a formatter extracts support information indicating if management information included in the transport packets includes predetermined items. A disc drive that records data on a recording medium having a management area and data area records the support information in the management area.
