Embodiment Construction

[0026] figure 1 It is a structural diagram of an embodiment of a parent-level optical disc device for managing optical discs according to the present invention. The optical disc device, such as an optical disc recorder or the like, includes an optical pickup 11, a VDR (Video Disc Recorder) system 12, an encoder 13, a decoder 14, an OSD (On Screen Display) generator 15. A microcomputer (Micom) 16 and a memory 17.

[0027] The VDR system may include a recording processor 120 and a playback processor 121 for recording data. The encoder 13 can convert externally input sound and video signals into digital data suitable for recording, and the decoder 14 can convert the playback sound and video data into an analog sound and video signal, so that peripheral equipment such as a television , loudspeakers or similar equipment can be accepted. The decoder 14 is capable of outputting analog audio and video signals.

[0028] The memory 17 is capable of recording and storing OSD graphic ...

Abstract

Method and apparatus for managing a parental level of an optical disc can allow a user to set a parental level of a data stream recorded and stored on a rewritable optical disc or write-once optical disc, and can record and manage the set parental level as navigation information such as for the optical discs. The method and apparatus allow the user to conveniently set or change the parental level of the data stream, refer to the parental level recorded and managed therefore, and carry out a parental locking operation such that children or teenagers cannot arbitrarily reproduce a data stream of an adult program. Further, a parental grade code, a supplemental parental grade code or if the parental code was generated using parental management information previously supplied by the user can be determined. Accordingly, an authorized user can determine whether the previous set grade code is changed illegally.

Description

1. Technical field [0001] The present invention relates to data storage and management, and a parental device and method for managing an optical disc. 2. Background technology [0002] Generally, optical discs can record and store a large amount of digital data. For example, a compact disc (CD) has a recording capacity of about 650M bytes, a digital versatile disc (DVD) has a recording capacity of about 4.7G bytes, and a A Blu-ray Disc (BD) has a recording capacity of about 23 Gbytes or more. Conventional optical disc devices such as optical disc players can read or reproduce a digital data stream on a read-only optical disc. [0003] A user can also operate an optical disc device such as an optical disc recorder to record and store desired image or sound data on a rewritable optical disc or a write-once optical disc. Moreover, the optical disc device enables the user to view and hear reproduced data as high-quality image and sound data through a screen matched thereto, fo...
