Problems solved by technology

[0010] However, users usually move desired content to a memory card after storing a large amount of content in a large-capacity HDD, and use the content outdoors. At this time, due to the applicable moving rules, the content in the HDD must be Delete. When moving the content to the memory card, the content is usually recorded on the memory card at a lower bit rate than when it was recorded on the HDD. Therefore, even if the content is moved to the HDD, it cannot be restored to the original High bit rate content. Therefore, even if the user wants to use the content outdoors first and then enjoy the content comfortably in the room again, he cannot enjoy the content with high image quality and high sound quality.

Embodiment approach 1

[0055] First, use figure 1 and figure 2 The configurations of the recording / reproducing device 110 and the external recording medium 160 according to Embodiment 1 will be described.

[0056] figure 1 It is a diagram showing the appearance of the recording / playback device 110 and the external recording medium 160 according to the first embodiment. The recording / playback device 110 is a recording / playback device such as a hard disk recorder or a DVD recorder. The external recording medium 160 is an example of the second recording medium, and the external recording medium 160 is a memory card having a semiconductor memory. The recording / playback device 110 has a slot 200 into which an external recording medium 160 is inserted.

[0057] figure 2 It is a block diagram showing the configurations of the recording / reproducing device 110 and the external recording medium 160 according to the first embodiment. The slot 200 ( figure 2 (not shown) is connected to the external re...

Embodiment approach 2

[0129] Next, the recording / reproducing device 110 and the external recording medium 160 according to Embodiment 2 will be described.

[0130] The configuration of the recording / playback device 110 according to the second embodiment is the same as that of the recording / playback device 110 according to the first embodiment. The structure of the external recording medium 160 of the second embodiment is the same as that of the external recording medium 160 of the first embodiment. Below, use Figure 9 ~ Figure 11 Operations of the recording / reproducing device 110 and the external recording medium 160 according to Embodiment 2 will be described.

[0131] In Embodiment 2, the operation of recording and reproducing the content compressed data A stored in the recording and reproducing device 110 on the external recording medium 160 will be described. The operation when the content compressed data A is stored in the recording / playback device 110 has already been described in Embodime...

Abstract

The present invention provides a recording and reproduction device capable of preventing content having details identical to the details of outputted content from being reproduced simultaneously withthe outputted content, and allowing the content to be reproduced in high quality. A recording / reproduction device (110) includes a recording area (115), a communication processing unit (119) capable of outputting the related content having details identical to details of the content recorded in the recording area (115) into an external recording medium (160), and an encoding / decoding processing unit (117) capable of obtaining unique information of the external recording medium (160). The encoding / decoding processing unit (117) changes a state of content recorded in the recording area (115) into a state irreproducible unless using unique information of the content, when the related content is outputted to the external recording medium (160); then reproduces the content recorded in the recording area (115) using the unique information, when the encoding / decoding processing unit (117) obtains the unique information.

Description

technical field [0001] The present invention relates to a recording / playback device that records content and plays back the content. Background technique [0002] In recent years, portable information terminal devices (hereinafter referred to as mobile terminal devices) such as mobile phones and Personal Digital Assistants (PDA: Personal Digital Assistants) have been popularized in the market. The mobile terminal device includes a visual transmission information unit and an auditory transmission information unit. The visual transmission information unit uses a small liquid crystal screen to visually transmit information to the user. The auditory transmission information unit uses speakers and earphones to transmit information to the user through hearing. General-purpose memory cards including nonvolatile memory such as flash memory (for example, IC cards such as SD cards (registered trademark) and memory sticks (registered trademark)) have also been widely used as recording ...
