In the following, the file identification and heading operations for each of the image / audio viewing devices 53 connected to the image / audio recording / reproducing device 1 configured as described above will be described.
For example, the image / audio viewing device 53 such as a television, a display, and a projector is compatible with a high-definition television receiver HDTV. Therefore, because of the increase in size of the image / audio viewing device 53, the installation location is fixed in the home for personal use, and the viewer is limited to a certain range such as family, friends, and acquaintances. Often. Also, in the installation of the image / audio viewing device 53 in an environment other than the home, the installation location is mostly fixed.

  On the other hand, camera / recording / playback devices such as camera-integrated recording / playback devices, digital cameras, mobile phones with shooting / recording functions, PDAs (personal digital assistants) with shooting / recording functions, etc., are miniaturized with higher image quality. The trend is progressing.

Can be viewed.

  Then, when viewing by connecting to the image / sound viewing device 53 at the moving place, there is a tendency that a common preference among the user, family, friends, and acquaintances appears in the viewed image and sound. Also, outside the home, content suitable for viewing at a specific installation location is often selected as an image and audio signal source. In other words, the content suitable for each image / audio viewing device 53 installed in a different place is different.

  For this reason, the playback history when connected to a plurality of video / audio viewing devices 53 and the playback history information of previously viewed images and audio files are stored in the video / audio recording / playback device 1 such as a camcorder or a digital camera. This makes it possible to cue from different playback start points for each connection partner.

Next, a method for storing and identifying the individual identification information in the audio / video recording / reproducing apparatus 1 will be described.
First, the individual identification information of the video / audio viewing device 53 of the connection partner and the reproduction history information of the reproduced / transmitted image and audio files are stored.
Next, the user who wants to view / listen connects the image / audio recording / reproducing apparatus 1 to the image / audio viewing / listening apparatus 53 via the communication means 52.

Through the communication means 52, the audio / video recording / reproducing apparatus 1 reproduces or transmits an image and audio to the audio / video viewing apparatus 53 and acquires the individual identification information from the audio / video viewing apparatus 53.
Next, the microcomputer 25 associates the source of the image and audio signal reproduced or transmitted to the specific image and audio viewing device 53 with the reproduced history, and obtains the individual identification information of the acquired image and audio viewing device 53. The data is stored in the nonvolatile memory 50 as a table.

FIG. 2 shows an example of the contents of the storage table in the nonvolatile memory 50 of the microcomputer 25.
In FIG. 2, the contents of this table include individual identification information “Company X / model name P / serial No. xxxxxx” 67 and “Company Y / model name Q / serial No. xxxxxx” of the connected video / audio viewing device 61. "68" and "Company Z / model name R / serial No.xxxxxx" 69 are stored.
As the file name 62 played back, A, D, E, G, K, M are stored in the individual identification information “Company X / Model name P / Serial No. xxxxxx” 67 and “Company Y / Model name Q “/ Serial No. xxxxxx” 68 stores B and C, and “Z company / model name R / Serial No. xxxxxx” 69 stores F.

Further, as the file total time 63, “3:45:20” is stored for A of the file name 62, “2:55:12” is stored for D, and “2:05:38” is stored for E. , G stores “1:37:21”, K stores “0:13:16”, and M stores “3:01:09”.
As the file total time 63, “0:29:19” is stored for B of the file name 62, “2:00:01” is stored for C, and “0:49:22” is stored for F. ing.

  Further, as viewing end date / time 64, “2004.10.10 / 18: 30: 45” is stored as A in the file name 62, and D is “2003.9.13 / 08: 12: 06”. Is stored, E is stored as “2003.8.22 / 03: 55: 17”, G is stored as “2004.9.14 / 15: 03: 10”, and K is stored as “2002.9.02”. / 13: 22: 01 ”is stored, and“ 2004. 4.28 / 15: 33: 01 ”is stored in M.

As the viewing end date / time 64, B of the file name 62 stores “2004.11.10 / 19: 56: 02”, and C stores “2004.11.12 / 09: 12: 45”. Is stored, and “2001.12.24 / 20: 13: 43” is stored in F.
Further, as the reproduction start point 65 of the target file, “0:00” is stored as A of the file name 62, “2:32:40” is stored as D, and “1:38:59” is stored as E. Is stored, G is stored as “00:00”, K is stored as “00:00”, and M is stored as “00:00”.

As the reproduction start point 65 of the target file, “0:00” is stored for B of the file name 62, “1:08:46” is stored for C, and “0:02:11” is stored for F. Is remembered.
As the playback end point 66, “0:54:13” is stored for A of the file name 62, “2:55:12” is stored for D, and “1:59:32” is stored for E. , G stores “1:37:21”, K stores “0:13:16”, and M stores “2:51:08”.

As the playback end point 66, “0:29:19” is stored for B of the file name 62, “2:00:01” is stored for C, and “0:45:54” is stored for F. ing.
The reproduction start point 65 and the reproduction end point 66 are represented by the time from the beginning of the file, and are obtained from the time code recorded in the file.
In this example, one recent history remains for one file. However, a history of a plurality of times may be stored and used as information for cueing processing to be described later. good.

Next, based on the information stored in the reproduction history acquisition process, the file reproduction to the connected audio / video viewing device 53 is cued.
FIG. 3 is a flowchart showing the reproduction start point designation process.
First, when viewing by connecting to a specific image / audio viewing device 53, the microcomputer 25 acquires the individual identification information of the connected image / audio viewing device 53 by the communication means 52 (step S1).

  Then, it is determined whether or not there is a connection history (step S2). If there is a connection history in step S2, the microcomputer 25 reproduces the reproduction history information of the connection partner image / audio viewing device 53 that matches the individual identification information. Is read from the non-volatile memory 50 (step S3), the most recently reproduced file that is most likely to be reproduced is identified from the information obtained from the reproduction history (step S4), and the reproduction start point is calculated.

An example of the algorithm for specifying the reproduction start point will be shown below.
That is, as the file selection, the file recently played back in step S4 is selected for the image / audio viewing device 53 as the connection partner. In the designation of the reproduction start point of where to reproduce from the selected file, there are the following four types of contents of the previous reproduction history. That is, there are four types: a) reproduced from the beginning to the middle, b) reproduced from the middle to the middle, c) reproduced from the middle to the end, and d) reproduced from the beginning to the end. Therefore, it is determined which is the previous playback start point and playback end point (step S5).

Here, when a) playback is performed from the beginning to the middle, b) when playback is performed from the middle to the middle, the playback end point is selected as the playback start point (step S8).
Also, c) when playing from the middle to the end, it is considered that there was an important factor in the content played last time, and the point where playback was started last time is selected as the playback start point (step S6).
Further, d) When the entire file is reproduced from the beginning to the end, it is considered that the entire target file is important, and the beginning of the object file is selected as the reproduction start point (step S7).

Further, in addition to the above four cases, including the case where e) the recording medium is removable and exchanged, etc., if there is no reproduction history for the target audio / video viewing apparatus in step S2, All information items are read (step S9), sorted in order of the recorded time (step S10), and a play list is displayed (step S11). Then, the head of the file selected as selectable by the viewer is designated (step S12).
The microcomputer 25 displays the file list in step S11 on the image display unit 17 or the connected image / audio viewing device 53 with the GUI function.

A display example of the above file list is shown in FIG.
In FIG. 4, in this list, the file name 71, the recording date / time 72, the recording time 73, and the file size 74 of the selected file are displayed with different colors or high-intensity highlights. Alternatively, a display designated by scrolling with an arrow or the like is also possible. This is selected by moving up, down, left and right by the user interface 26.

In this case, the beginning of the selected file is designated as the playback start point.
If there is a reproduction instruction (step S13), reproduction is started from the designated point (step S14). In addition, representative thumbnail images of signal sources can be displayed together with this list.

  Further, the determination material may be further increased from the above reproduction start point designation processing, and selection may be made with fine classification. For example, as f), a) When playing from the beginning to the middle, b) When playing from the middle to the middle, if the playback end point is halfway as a file, but d) From the beginning to the end Judged to be the same as played.

Whether it is “close to the end” is determined by the remaining time until the end. If the remaining time is only a few seconds, it can be said that it is almost watched.
Also, as g), when c) is played from the middle to the end, if the playback start point in the middle of the previous playback is very close to the end of the file, it is determined that the video has been almost watched as in f) above. d) Determine the playback start point in the same way as playback from the beginning to the end.

Through the above operation, the user can easily and continuously reproduce and view images and sounds enjoyed in the past.
As a result, the stored list for each image / audio viewing device 53 is not connected to the image / audio viewing device 53 by an operation on the user interface 26 such as a switch of the main body or GUI, but the image / audio viewing device such as the LCD panel of the main body. 53 or a connected external video / audio viewing device 53.

According to the above-described embodiment, the individual identification information of the connected image / audio viewing device 53 and the reproduction history of the image / audio source content output to the image / audio viewing device 53 are stored as information in association with each other. Thereafter, by determining the file to be reproduced and the cue position from the information stored at the time of viewing on the image / audio viewing device 53, the user who views the image / sound output to the image / audio viewing device 53 has no relation to the preference. The content can be avoided and the time for searching for the reproduction start position can be saved, and the reproduction can be easily performed from the point of expectation.
This is particularly effective for file selection and cueing when a file is played back by a camera-integrated recording / playback apparatus having a large capacity recording medium, a digital camera, or the like.

  It goes without saying that the configuration can be changed as appropriate within the scope of the present invention, not limited to the embodiment described above.
