In the future, it is expected that it will be difficult to find a desired video content from the recorded one, while the capacity of the HDD will be increased and a lot of video content can be stored.
For example, with respect to titles of EPG (electronic program guide, electronic program guide), there are the same title, simplification of illegal titles, titles in which a plurality of programs are combined, and the like. Also, there are devices that automatically record according to the viewer's preference based on keywords, recording results, etc., and it is difficult to specify desired video content from the title.

Conventionally, video content search has been performed by specifying a desired video content by displaying a list of HDD recorders or televisions, or reproducing each video content each time. However, depending on the device, there are devices that cannot be displayed or reproduced during dubbing, and there are problems such as waiting for the end of dubbing or taking a long time to search and occupying the device. Furthermore, in the case where there are a plurality of external HDDs, according to the conventional technology, the search cannot be performed unless the HDD is installed in an HDD recorder or a TV each time, and the insertion / removal of the external HDD is a complicated operation.

On the other hand, what is described in Patent Document 1 is to notify the location of the recording medium on the search device side. Therefore, there is no means for informing from the recording medium side.
In addition, what is described in Patent Document 2 is that a recorded content display device reads an RF tag signal affixed to a recording medium and displays program explanations, thumbnails, and the like. The program information is not read from the RF tag, but the information is read from the recording device.

Note that what is described in Patent Document 1 also refers to an RF tag as means for secondary storage of video content information, and assumes that the recording medium is DVD or HDD. However, large capacity HDD
In this case, the capacity of the RF tag is insufficient to bring out convenience.
