Problems solved by technology

[0003] In addition, in relation to the above-mentioned technical field, Patent Document 2 takes "providing an apparatus and method capable of restricting the recording of digital information requiring copyright protection on a recording medium in a recording and reproducing apparatus" as the subject, and as its solution, It is described that "the recording and playback control circuit is configured to convert the information into converted digital information of a predetermined bit rate together with the information (Copy OneGeneration) when the copy control information is information that allows one-generation copying, and the above-mentioned number of times of copying." Information is recorded on the above-mentioned recording medium. According to the copy control information, although the above-mentioned digital information or the above-mentioned converted digital information is moved to the recording medium of the recording device connected to the playback device, although it is prohibited from copying again (Copy No More), Reducing the possible number of times, updating the information on the number of times of duplication, and re-recording the digital information or the converted digital information signal, the copy control information and the information on the number of times of duplication in the recording medium at the same time, making the digital information signal or the converted digital information signal information cannot be reproduced

Abstract

The invention provides a control method, a recording device and a recording representation device. In the case of allowing recording one generation of a digital broadcasting program, at the same time of executing copy control, convenience in use can be improved. The control method is to receive digital contents and copy control information of the digital contents, including the steps of: when thereceived copy control information displays copy generation information allowing copy-one-generation, setting the digital contents in a copy-prohibited state and recording when the recording medium isa removable recording medium; setting the digital contents in a copy-prohibited state and recording when the received copy control information indicates prohibition of a plurality of copies and the recording medium is an internal recording medium which records digital contents while encrypting the digital contents; setting the digital contents in a replicable state up to a prescribed replicable number when the received copy control information indicates permission of a plurality of copies.

Description

technical field [0001] The present invention relates to copy control of content. Background technique [0002] Regarding the above-mentioned technical field, in Patent Document 1, "When the information (Copy One Generation) that allows only one generation of copying is rewritten to the information that prohibits further copying (Copy NoMore), the usability at this time is improved." The content is a problem, and as its solution, it is described, "Allow only one generation of copy (Copy OneGeneration) within a specified time after recording, so as to supplement the part where the recording was interrupted due to an accident during recording. And, on the medium Record two identical streams, use one for normal viewing, and move the other to another medium as needed and save it." [0003] In addition, in relation to the above-mentioned technical field, Patent Document 2 takes "providing an apparatus and method capable of restricting the recording of digital information requirin...
