RECORDING METHOD, RECORDING APPARATUS, REPRODUCTION METHOD AND REPRODUCTION APPARATUS

摘要

The present invention aims to enable revision of additional information buried in contents data with less burden on hardware. For this purpose, a predetermined amount of inputted contents data is temporarily stored in buffer means, the additional information buried in the contents data being detected from the contents data temporarily stored in the buffer means, the contents of the detected additional information being estimated, the contents data being made to be recorded in a predetermined medium when estimated that the contents data can be recorded, and the contents data being made not to be recorded in the medium when estimated that the contents data must not be recorded. In addition, when estimated that revision of the additional information is necessary, the relevant part of data stored in the buffer means is revised while it is being stored in the buffer means. <IMAGE>
