(First embodiment)
A first embodiment of the information signal reproducing apparatus of the present invention will be described with reference to FIG.

  The information signal reproducing device of this embodiment requires the following configuration as a premise. A recording means for recording an MPEG2-transport stream on a recording medium and acquiring copy control information from the transport stream; a reproducing means for reproducing the transport stream while analyzing the copy control information from the recording medium; Display means for displaying a GUI on a video screen to be reproduced is provided. In addition, audio output means for mixing audio and beep during playback is provided. Further, a copy prohibition information dedicated display segment is provided for the FL tube. In addition, an information file is generated as a separate file for a stream having copy control information as control information, and a part of the information file includes copy control information.

  This will be described in detail with reference to FIG. The information signal reproducing apparatus of this embodiment is configured as a part of the information signal recording / reproducing apparatus. FIG. 1 is an overall block diagram of an information signal recording / reproducing apparatus including the information signal reproducing apparatus of the present embodiment. As shown in FIG. 1, an information signal recording / reproducing apparatus 100 includes a demultiplexer 1, a playback module 2, a record module 3, an IDE controller 4, an HDD 5, a removable drive 6, an MPEG decoder 7, and a video. The compositor 8, the graphic controller 9, the audio mixer 10, the audio controller 11, the CPU 12, the FL controller 13, and the information file generation unit 20 are provided, and the CPU 12 controls all of these components.

  The information signal reproducing apparatus of this embodiment corresponds to a part of the information signal recording / reproducing apparatus 100 excluding the record module 3, the HDD 5, the removable drive 6, and the information file generating unit 20.

  The information signal recording / reproducing apparatus 100 records and reproduces an MPEG2-transport stream. The MPEG2-transport stream includes copy control information indicating content copy prohibition.

  When an MPEG2-transport stream is recorded in the information signal recording / reproducing apparatus 100, the stream received by a tuner (not shown) and passed through the demultiplexer 1 is stored in the HDD 5 or the removable drive 6 by the record module 3. Written to optical disc. At that time, the data of the transport stream is stored in a buffer managed by the record module 3, and the IDE controller 4 determines whether or not copying is prohibited for the data stored in the buffer based on the copy control information. Analysis is performed, and the information file generation unit 20 generates an information file as a separate file from the content. Both content and information files are recorded on the optical disk of the HDD 5 or the removable drive 6. As described above, a plurality of files are recorded on the HDD 5 or the optical disc (6).

  FIG. 2A shows an MPEG2-transport stream corresponding to one content. The MPEG2-transport stream is composed of a plurality of packets, and copy control information is included in the packet header of each packet. In the example of FIG. 2A, a copy-prohibited part and a copy-permitted part exist in one content. In addition, although not shown, there is a copy prohibited for one whole content and a copy permitted for the entire content.

  As shown in FIG. 2A, copying is prohibited for the part indicated by the code B to the code C (block 1) and the part indicated by the code D to the code E (block 3). In this case, the information file generation unit 20 generates an information file as shown in FIGS. 2-2 and 2-3. In the information file, for each block included in the stream corresponding to one content, information indicating the start point and end point indicating the block range, and information indicating whether or not the block is copy-protected (copy status) ) Is included.

  As shown in FIG. 1, in the information signal recording / reproducing apparatus 100 (information signal reproducing apparatus), when the stream recorded on the HDD 5 or the optical disc (6) is reproduced, the stream is read by the playback module 2. After that, the signal is demultiplexed by the demultiplexer 1 and decoded by the MPEG decoder 7, and the video signal and the audio signal are respectively output to a TV device (not shown).

  When the user selects the function of copying the stream information recorded on the HDD 5 or the optical disk (6), the CPU 12 controls the video compositor 8 and the graphic controller 9, for example, as shown in FIG. On the screen of the file copy menu, the luminance of the video signals constituting the title screens 22c and 22e is reduced and displayed.

  The operation when the file copy menu is displayed will be described with reference to FIGS. Each operation in FIG. 3 is performed by the CPU 12 executing a program. FIG. 4 shows the file copy menu 21 displayed on the TV screen 40.

  In the file copy menu 21, there are six thumbnails (screens (title screens) 22 a to 22 f (content specifying information)) for identifying each of a plurality of titles (contents) recorded on a copy source recording medium (for example, HDD 5). It is displayed.

  First, in step S1, for example, when the user wants to copy a content file recorded in the HDD 5 to the optical disc (6), he / she operates the remote controller or the like to select the file copy function.

  Next, in step S2, the CPU 12 determines whether or not there is a title to be displayed on the file copy menu in response to the signal indicating that the file copy is selected from the user in step S1. As a result of the determination, if it is determined that there is a title to be displayed, the process proceeds to step S3. On the other hand, if it is determined that there is no title to be displayed, this control flow ends.

  In step S3, it is determined whether or not the number of titles that can be displayed on one screen (6 in the example of FIG. 4) has been exceeded. As a result of the determination, if not exceeding, the process proceeds to step S4, and if not, the control flow ends.

  In step S4, one title is read, and the copy control information of the title is referred to, and it is determined whether or not a copy-prohibited area is included in at least a part of the title. As a result of the determination, if the copy of the entire title is not prohibited, the title screen is displayed as a thumbnail as it is (with normal luminance) (step S6).

  On the other hand, if the result of determination in step S4 is that copy of the entire title is prohibited, the brightness is set to, for example, 50% compared to the normal time (step S5), and only a part of one title is set. If the copy-prohibited area is included, for example, the brightness is set to 80%, for example, compared to the normal time (step S5), and the title screen is displayed as a thumbnail (step S6). Next, the operation after step S2 is repeated again for the next title (step S7).

  In FIG. 4, the title screens 22 a, 22 b, 22 d, and 22 f are displayed with normal brightness. The title screen indicated by reference numeral 22c is displayed with a luminance of 80%, and the title screen indicated by reference numeral 22e is displayed with a luminance of 50%. In the present embodiment, a configuration is adopted in which a copy-prohibited title is notified by making a difference in the brightness of the title screen in a plurality of thumbnail-displayed title screens. It is possible to intuitively determine whether there is a copy, and it is not possible to overlook that copying is prohibited.

  According to the present embodiment, by reducing the brightness of the title screens 22c and 22e, the user is easily notified that the title is a copy-prohibited title. In this case, information indicating whether copying is prohibited is not superimposed on the title screens 22c and 22e. That is, for example, as represented by the title screen of this embodiment, an image of a file to be copied or information for specifying the file (including the file name, recording date and time, recording time, etc.) is displayed. When the file is displayed, the image of the file or the display of information for specifying the file is not hidden or the information is not lost.

  Accordingly, it is possible to notify whether or not copying is prohibited while preventing the user from visually recognizing the title screen (the image of the file to be copied or information for specifying the file).

  Instead of the above, copying is prohibited by blinking a frame portion (not shown) received as an area other than the title screens 22a to 22f outside the title screens 22a to 22f. May be shown. Alternatively, the number of the title screens 22a to 22f for which copying is prohibited may be output by voice to indicate that copying of the title is prohibited.

  Further, according to the present embodiment, it is possible to notify the user of whether the entire title is copy-prohibited or only a part of the title is copy-prohibited by the difference in luminance. Further, by changing the blinking pitch and sound of the frame portion, it is possible to notify the user whether the entire title is prohibited from being copied or only a part of the title is prohibited from being copied.

(Second Embodiment)
Next, a second embodiment will be described with reference to FIGS.
In the second embodiment, description of the contents common to the first embodiment is omitted.

  In the present embodiment, a case will be described in which a part of a content file is designated by the user and the designated range is copied. Here, as shown in FIGS. 2-1 to 2-3, there is a case where copying is partially prohibited in a stream corresponding to one content.

  In this case, as shown in FIG. 6, when the portion where copying is prohibited is being played back, the display frame 62 of the screen 61 being played back is blinked, whereby the image 61 being played back is displayed. Notify the user that copying is prohibited. That is, in the editing screen 63 of the information signal recording / reproducing apparatus 100 displayed on the TV screen 40, the screen 61 being reproduced is not hidden at all, and the screen 61 provided outside the screen 61 being reproduced is provided. By flashing the display frame 62 which is a different area, the user is notified that copying of the image 61 being reproduced is prohibited.

  Thereby, the user can be notified of the copy-prohibited area without hindering (disturbing) the viewing of the original content information by the user. In this case, the same effect as described above can be obtained by reducing the luminance of the reproduction screen 61 or generating a beep sound while the copy prohibited area is being reproduced.

  Further, as shown in FIG. 7, a dedicated segment (area) 71 for displaying information indicating whether copying is prohibited is provided on the display unit (FL tube) 70 of the housing of the information signal recording / reproducing apparatus 100. Information indicating that copying is prohibited in the segment 71 of the display unit (FL tube) 70 when reproduction of the portion where copying is prohibited is performed on a TV screen (not shown). (In FIG. 7, the characters “NOT COPY”) are displayed.

  In FIG. 7, the number “2” indicated by reference numeral 72 is a number for specifying the title being played back, and “0: 15.30” indicated by reference numeral 73 is the playback time of the title is 15 minutes and 30 minutes. Indicates seconds. As described above, the information indicating whether or not copying is prohibited is the display of the sub information so that the user's visual recognition of the content number 72 and the playback time 73 information, which is the sub information related to the content being played back, is not hindered. It is displayed in a dedicated area 71 different from the area. Thereby, it is possible to notify the user that the area is a copy-prohibited area without preventing the user from visually recognizing the sub-information related to the title being reproduced.

  The operation of the second embodiment will be described with reference to FIG.

  As described above, file copying may be performed for a part of the file specified by the user. FIG. 5 shows an operation when notifying the user of an area where copying is prohibited when the area to be copied is designated by the user. In this operation, when the copy-prohibited area is being played back during playback of the title, the user is notified that the area being played back is a copy-prohibited area. It is notified that it is a copy-prohibited area in such a way that the visual recognition is not hindered. Hereinafter, a description will be given with reference to FIG.

  First, in step S1, for example, when a part of a content file recorded in the HDD 5 is to be copied to the optical disc (6), the user operates a remote controller or the like to perform a file copy area designation function. select.

  Next, in step S2, the CPU 12 controls the video compositor 8 and the graphic controller 9 in response to the signal for selecting the file copy area designation from the user in the step S1, and as shown in FIG. As described above, the editing screen 63 for designating the file copy area is displayed on the TV screen 40.

  Next, in step S3, when the user designates the file copy area from point A to point B in FIG. 6, the title is reproduced on the reproduction screen 61 so that the designated area can be determined. At this time, in the above example, the reproduction is started from the point A designated by the user among the titles recorded in the HDD 5.

  When point B is designated by the user, the title is continuously played up to point B (reproduction end) (steps S4 and S10). If point B is not specified, playback is performed to the end of the title (steps S4 and S10).

  At this time, in the above example, the playback module 2 reads the title data recorded in the HDD 5 (step S5), and checks the stream itself every time the read is performed. When played back (step S6-Y), the CPU 12 controls the video compositor 8 and the graphic controller 9 to blink the outer frame 62 of the playback screen 61 (step S7). Alternatively, reproduction is performed with the luminance of the reproduction screen 61 lowered (step S7).

  Instead of step S7 or together with step S7, the CPU 12 can control the audio mixer 10 and the audio controller 11 to mix and play sound such as a beep sound. Further, when the copy prohibited area is reproduced instead of step S7 or together with step S7, the CPU 12 controls the FL controller 13 as shown in FIG. Information indicating that copying is prohibited can be displayed in a dedicated area different from the information display area. Alternatively, the CPU 12 can control the FL controller 13 to indicate that copying is prohibited by blinking the display of the sub-information relating to the title being reproduced in the FL tube 70 or changing the luminance.

  The first to second embodiments can be applied to all products that handle content including copy control information. For example, the first to second embodiments can be applied to DVD playback devices, Blu-ray playback devices, HDD playback devices, VTRs, and the like. .
