Description

  The present invention relates to a recording / reproducing apparatus and method, and more particularly to a recording / reproducing apparatus corresponding to copy-once content such as digital broadcasting and a recording / reproducing method therefor.

  Usually, digital broadcasts are subject to copy-once restrictions, so that the content recorded on a recording / playback device (hereinafter referred to as a recorder) can be viewed on an external playback device (hereinafter referred to as a portable playback device). When moving to a device, the contents of the recorder must be erased. At this time, even if the resolution of the portable playback device is low or the HDD capacity is small and it is necessary to down-convert from MPEG2 to MPEG4, the content file on the recorder is deleted, and again from the portable playback device. Even if the content is moved to the recorder, the high-definition video is lost.

  Therefore, it is conceivable that the same content is recorded simultaneously for home viewing and for portable viewing (multiple recording) by a method such as mounting two digital tuners on the recorder. In this case, even if one content is edited or viewed halfway, such information is not reflected in the other content.

  For example, if you are watching on a television device connected to the recorder halfway through a program, and you want to watch the rest on a portable playback device, the portable playback device must manually fast-forward to where it was viewed on the television device. Don't be. Moreover, even if one content viewed on a television device is edited to create a collection of famous scenes as a playlist, it is not reflected in the other content, so that it is necessary to recreate the playlist.

Conventionally, in the case where a plurality of users view one title separately, it has been disclosed that each user can play back from the position where the playback was stopped (see, for example, Patent Document 1). This is a designation means for designating one resume information among the resume information stored in the storage means as the currently selected resume information when the resume information indicating the reproduction stop position is additionally registered in the storage means. And an input means for changing the designation as the resume information currently selected during reproduction to other resume information stored in the storage means.
