Zusammenfassung:The invention relates to a demonstration data recording and reproduction method and recording medium thereof, wherein the non-encipherment data for demonstration is transformed into source data consistently in time, which is in the recording format suitable for recording medium as a DVD readable memory device, the data for demonstration can thus be searched and reproduced, as a result, the users will pay for the decoded rendition code of the enciphered data. 本发明为一种演示用数据记录和再现方法及其记录媒体。经防止复制码的附加记录,为了演示密码加密的数据和将其已加密的数据内容,将非密码化的演示用数据,把时间上连续性传送的源数据,以DVD可读存储器一样适合于记录媒体的记录格式进行的同时,能把上述演示用数据搜索再现出来,备有光盘装置的用户,在没有解读码的情况下,事先能确认DVD加密的记录媒体内的加密,并且载入的数据是不是自己所要的数据,这样,用户自然会付费购买上述密码数据的解读再现码,并且通过互连网联机灵活应用诸如将以密码加密提供EMD音频数据的数字数据。
