Problems solved by technology

However, the billing method (clearance: clearance) in the network is often different for each content provider, and if charging processing based on controlled copying is implemented on the playback device side, the manufacturer of the playback device must support these content providers. liquidation
Such support for the liquidation of each content provider imposes a great burden on the manufacturer of the playback device, and as a result, the possibility of controlled copy adoption of home appliances becomes small.

Embodiment approach 1

[0106] First, the form of the usage behavior among the implementation behaviors of the playback device of the present invention will be described. figure 1 It is a figure which shows an example of the form of the usage behavior of the reproduction|regeneration apparatus of this invention. figure 1 Among them, the playback device of the present invention is the playback device 101. This playback device 101 is used to provide movie works to a home theater system formed of, for example, a remote control 102 and a television 103 . Furthermore, the playback device 101 has an insertion port for inserting a removable storage medium 104 such as an SD memory card, memory stick, CF card, SM card, or MMC card, and an insertion port for externally connecting a BD drive 106 .

[0107] The above is the description of the usage mode of the playback device of the present invention. Next, a recording medium (media) to be played back by the playback device of the present invention will be des...

Embodiment approach 2

[0197] In Embodiment 2, controlled copying to a removable storage medium in which recordable file names are limited will be described. Since the file recorded on the BD-ROM adopts the Long File Name (LFN) format, it is possible to record a file name having a file name of 10 characters or 20 characters or an extension of 4 characters or 5 characters. On the other hand, removable storage media often employ a file system in which a file name is limited to a maximum of 8 characters, a directory name to a maximum of 8 characters, and an extension to a maximum of 3 characters. Therefore, it may not be possible to copy the file names recorded on the BD-ROM to the removable storage medium as they are.

[0198] Figure 14 It is a diagram showing controlled copying in consideration of file name restrictions of removable storage media. When copying a file on a BD-ROM with a file name of 9 characters or more or an extension of more than distribution characters to a removable storage med...

Abstract

Since managed copy requires consumption of a plenty of resources, there is a problem that if managed copy controlled by the reproduction device side and BD-J application execution on a recording medium are simultaneously operated, resource shortage is caused. Provided is a reproduction device in which during a managed copy, a disc is virtually removed for the BD-J application so as to limit access to the disc, thereby avoiding the resource conflict between the managed copy and the BD-J application execution, which enables simultaneous operation of the managed copy and the BD-J application execution.

Description

technical field [0001] The present invention relates to a reproduction device for reproducing video data recorded in a recording medium such as a BD-ROM (Blu-Ray Disc Read Only Memory), and more particularly relates to transferring the video data recorded in the recording medium to A technique of recording on a recording medium other than this recording medium (managed copy: Managed Copy). Background technique [0002] Controlled copy refers to transferring digital streams and application programs (hereinafter referred to as "applications") recorded on read-only recording media such as BD-ROM to other optical discs (BD-R, BD-RE, DVD-R , DVD-RW, DVD-RAM, etc.), hard disk, removable storage media (SD memory card, memory stick (memory stick), CF (Compact Flash) card (registered trademark), SM (Smart Media) card, MMC (Multimedia When duplicating a readable and writable recording medium such as a Card) card, etc.), unlimited duplication is not allowed, communication with a serve...
