Japanese Patent No. 5281721 JP 2008-227641 A

  However, the prior art has the following drawbacks. First, since the technology of Patent Document 1 is configured to set the output parameter to the television by the operation of the viewer's remote control device, in order to set the output parameter appropriately, the contents and the reproduction of the external device It is necessary for viewers (users) to accurately grasp both performances. However, the playback performance of the external device is diverse, such as the resolution and the type of display screen aspect ratio, even in video settings, and it is difficult for the viewer to grasp the playback performance of the external device in detail. Therefore, when based on the operation of the viewer, there is a limit to appropriately setting the output parameter.

  In the technique of Patent Document 1, since the TV setting (output parameter such as image quality) at the time of content recording or reserved recording is uniformly adopted as the output parameter to be set, the user's remote control operation Is originally unnecessary, but the TV setting at the time of recording or reserved recording is not necessarily optimal. Therefore, in actual content reproduction, the viewer often needs to perform remote control operations to appropriately set output parameters such as image quality while watching and listening to reproduced video and audio.

  On the other hand, the technique of Patent Document 2 is configured to store in advance a matching data table in which items representing the content (type) of content and a plurality of items representing the setting details of the television are associated with each other. It is necessary to play the content on an external device (such as a television) that has been determined. Therefore, for example, in a configuration in which various televisions and audio surround devices can be connected to a recording / playback device such as a BD (Blu-ray Disc) recorder and the content can be played back, external devices such as the connected televisions and audio surround devices Playback performance, for example, the resolution of the video on a television and the size of the display screen differ depending on the connected television, and the number of speakers differs depending on the audio surround device, such as 5.1 ch or 7.1 ch. Even if audio is output uniformly with the output parameters set in advance in the matching data table, it is often assumed that the playback content can be optimally played back with higher resolution video and surround sound with more speakers. The

  Furthermore, in the technique described in Patent Document 2, the current television setting (output parameter) is always acquired at the time of content reproduction, and this television setting is checked against the matching data table to determine whether there is matching. If there is no need to change the setting, the acquisition of the current TV setting and the collation with the matching data table are essentially unnecessary and useless.

  In view of the above, the present invention has an object to connect a recording / playback apparatus such as a BD (Blu-ray Disc) recorder to the recording / playback apparatus without requiring a user to change an output parameter (remote control operation). Regardless of the type (playback performance) of an external device such as a television or an audio surround device, the content is to be played back with more appropriate video and audio depending on the content to be played back.

  In order to achieve the above object, in the present invention, information on the playback performance of an external device connected to the recording / playback apparatus is acquired, and the acquired information on the playback performance of the external device and content such as the program name and genre of the content Depending on the content, the video and audio output settings of the content to be reproduced are determined more appropriately.

  Specifically, the main claims are as follows.

  A recording / playback apparatus according to claim 1 manages a storage unit that stores content, a connection unit that can be connected to an external device, an information acquisition unit that acquires attribute information of the external device, and recording and playback of the content For each content, the management unit determines an output setting to the external device corresponding to the reproduction of the content based on the information about the content and the attribute information of the external device. It is characterized by that.

  With the above configuration, according to the first aspect of the present invention, the attribute information of the external device connected to the connection unit of the recording / playback apparatus is acquired by the information acquisition unit. Based on the acquired attribute information of the external device and the content of the content to be played back (program name, genre, etc.), the management unit then transmits video and audio to the external device that supports playback of the content to be played back. Determine the output settings.

  Therefore, no matter what video or audio playback performance is connected to this recording and playback device, considering both the playback performance of the connected external device and the content content, The output setting to the external device can be determined so that the reproduction of the content becomes more appropriate. For example, even if the content (resolution) of the content to be played back is 480i, if the resolution of the video of the connected television (external device) is high (for example, 1800p), the video to the television (external device) Since the resolution output setting can be determined as the resolution (1800i), it is possible to reproduce the video with higher definition than the video according to the content (resolution) of the content.

  In addition, since the management unit automatically determines the output setting to the external device, the user (viewer) does not need to know the details of the content and the attribute information including the reproduction performance of the external device. Therefore, even if the user (viewer) knows what output settings are appropriate for the external device according to the content, or has no knowledge of the attribute information of the connected external device, the video and audio of the content to be played back Can be viewed in a more appropriate state.

  Furthermore, since the output setting to the connected external device is determined based on the attribute information of the external device acquired by the information acquisition unit, the output setting at the present time (during recording or scheduled recording) as in the past. More appropriate output setting can be surely achieved as compared with the case of using (the output setting which may not be optimal) as it is.

  In addition, unlike the prior art, there is no need to acquire the current TV setting (output parameter), prepare a matching data table, or check the acquired TV setting against the matching data table every time content is played. So there is no waste.

  Further, in the recording / playback apparatus according to claim 6, when the information related to the content and the attribute information of the external device partially overlap, and the overlapped information does not match, the management unit The setting of output to the external device is determined with priority given to partially overlapping attribute information.

  In this recording / playback apparatus, since the output setting to the external device is determined with priority given to the attribute information of the external device, for example, the video resolution and the number of channels of the audio surround device included in the content-related information are smaller than the external device. Even in such a case, it is possible to reproduce the video and audio of the content by maximizing the reproduction performance of the external device.

  The recording / playback apparatus according to claim 7, wherein the storage unit stores information related to the recording target content, attribute information about the external device, and the attribute information of the external device, when the content is recorded by the management unit. The determined output setting to the external device is stored.

  Therefore, in the present recording / playback apparatus, when the content is recorded, the determined output setting to the external device is stored in the storage unit in association with the content. Therefore, when the content is played back, It is only necessary to read out the output setting, and it is not necessary to determine the output setting to the external device each time.

  9. The recording / playback apparatus according to claim 8, further comprising an operation unit that receives an instruction to change output settings to the external device, wherein the management unit is configured to determine the external device determined based on the instruction received by the operation unit. The output setting is updated.

  In this recording / playback apparatus, for example, the viewer can update the output setting to the external device by operating the operation unit while viewing the content reproduced with the determined output setting to the external device. The viewer's tastes and preferences can be reflected in the playback.

  The recording / playback apparatus according to claim 9, wherein the management unit is similar in content already stored in the storage unit to information newly stored in the storage unit, and the external device. If there is similar content with the same attribute information, the output setting for the external device associated with the similar content is determined as the output setting for the external device associated with the content newly stored in the storage unit. It is characterized by doing.

  Therefore, in the recording / playback apparatus, when new content is recorded, if there is similar content, the output setting to the external device associated with the similar content is used as the output setting of the recording target content. Therefore, if the output setting of the similar content has already been changed or updated by the viewer, for example, the content can be reproduced with more appropriate video and audio reflecting the viewer's preference and commitment.

  In the recording / playback apparatus according to claim 10, when the management unit deletes the content stored in the storage unit, the management unit stores information related to the content stored in association with the content, attribute information of the external device, and the external device. The output setting is stored as it is.

  In this recording / playback apparatus, even if the content itself (main part) is deleted, information related to the content, attribute information of the external device, and output setting to the external device remain in the storage unit. More minutes. Accordingly, a more appropriate output setting can be selected, and the reproduction of the content is optimally reflecting the user's (viewer's) preferences and preferences.

  In the recording / playback apparatus according to an eleventh aspect, the management unit stores a plurality of output settings in a storage unit in association with one content to be recorded.

  Therefore, in the present recording / playback apparatus, one of a plurality of output settings can be selected when the content is played back, so that the output setting (for example, a setting for reducing the sound) corresponding to the playback situation (eg, night time zone). Etc.).

  The recording / playback apparatus according to claim 12, wherein when the content is played back, the management unit uses the attribute information of the external device acquired by the information acquisition unit during the playback and the attribute information of the external device associated with the playback target content. If they do not match, the output setting to the external device corresponding to the playback of the playback target content is made based on the information related to the content associated with the playback target content and the attribute information of the external device at the time of playback. It is characterized by making a new decision.

  In the recording / playback apparatus according to claim 13, the management unit stores the attribute information of the external device at the time of playback and the newly determined output setting to the external device in association with the content to be played back. It memorize | stores in a part.

  Therefore, in these recording / playback apparatuses, even when the external device connected at the time of recording is removed and changed to a new external device having different attribute information such as playback performance at the time of playback, the new external device Since the output setting is newly determined, the content can be played back with more appropriate video and audio that fully exhibits the playback performance of the new external device. In addition, since the output setting for the new external device is stored in the storage unit, it is not necessary to determine the output setting for the new external device every time the content is reproduced.

  As described above, according to the present invention, in a recording / playback apparatus to which an external device having various playback functions can be connected, the connected external device can be connected regardless of the playback performance. Since the device attribute information is acquired and the output setting to the external device is automatically determined based on the acquired attribute information and information about the content, the remote control operation of the user (viewer) and the playback performance of the external device are determined. The content can be played back with more appropriate video and audio in consideration of the playback performance of the external device without requiring knowledge.

<Operation of the content management unit of the BD recorder>
Next, the operation of the content management unit 165 of the BD recorder 10 will be described in detail.

(Operation during recording)
First, the operations of the content management unit 165 and the HDMI control unit 130 when recording content (video / audio data) on a BD will be described.

  FIG. 5 is a flowchart for explaining the operations of the content management unit 165 and the HDMI control unit 130 during content recording. In the figure, in step S1 (first step), the content management unit 165 acquires information (content information) related to the recording target content specified by the remote controller 110 from the user. This content information includes EPG (Electronic Program Guide) information which is a television program table received and acquired from the digital program broadcast by the communication processing unit 162, and EIT (Event Information Table) information which is television program information of the recording target content itself. And get from. This content information is, for example, program information of the content, and includes the title, genre, subtitle, summary, video / audio format, video language setting, viewing restriction, subtitle setting, presence / absence of audio Dolby, etc. Information. Specifically, as shown in FIG. 6 (a), the content information includes a title “program name 00”, a genre “period drama”, and a video format (resolution / display screen size (screen aspect). Ratio) is “480i / 4: 3”, the audio format is “7.1ch surround”, the viewing restriction is “viewable from 12 years old”, and the caption setting is “subtitled” information.

  Next, in step S2 (second step) in FIG. 5, the HDMI control unit 130 is connected to the BD recorder 10 through the HDMI cables 21 to 23 for content reproduction external devices, that is, the TV receiver 30 and the AV receiver 20. As the attribute information, information related to video and audio reproduction performance is acquired. Specifically, the EDID information acquired by the EDID control unit 130 and stored in the storage unit 150 is received from the communication processing unit 162, and information regarding the reproduction performance of these external devices is acquired from the EDID information. To do.

  The EDID information acquired by the EDID control unit 130 is, for example, the corresponding resolution and the size of the video screen in the TV receiver 30, and may include brightness, contrast, hue, and the like. The AV receiver 20 may include a compatible audio format, the number of speakers, and the like. For example, the information regarding the reproduction performance, which is the attribute information of the TV receiver 30 and the AV receiver 20, can be simply illustrated. As shown in FIG. 6B, the resolution of the TV receiver 30 is “1080p”, and the video screen is displayed. The size is “16: 9”, and the surround sound that can be handled by the AV receiver 20 is the information “5.1ch surround” because the 5.1ch sound surround device 40 is connected.

  Subsequently, in step S3 (third step) in FIG. 5, the content management unit 165 acquires the content information of the content to be recorded and the attributes of the TV receiver 30 and the AV receiver 20 connected to the BD recorder 10. Based on the information regarding the video and audio reproduction performance, which is information, the respective output settings to the TV receiver 30 and the AV receiver 20 corresponding to the reproduction of the recording target content are determined for each recording target content. For example, based on the content information (program information) in FIG. 6A and the information regarding the reproduction performance of video and audio, which is the attribute information of the TV receiver 30 and the AV receiver 20 in FIG. Output settings from the BD recorder 10 shown in FIG. 5C to the TV receiver 30 and the AV receiver 20 are determined so that the playback video and playback audio are more appropriate. This will be specifically described as follows.

  6A to 6C, the video format (resolution / display screen size) of the content information is “480i / 4: 3”, while the resolution of the TV receiver 30 is “1080p”. Since the screen size is “16: 9”, the resolution and the video screen size are the resolution of the HD receiver 30 and the video screen sizes “1080i” and “16: 9”. It is best to set the output to. In this video output setting, since the video of “480i” is converted (up-converted) to “1080i”, the noise reduction setting is set to “on” and the super-resolution setting is set to “on” so as to suppress deterioration in image quality. It is best to set the output. On the other hand, the audio format of the content information is “7.1ch surround”, but since the audio format of the AV receiver 20 is “5.1ch surround”, the audio receiver 20 can support the audio output setting. “1ch surround” is optimal. Since “subtitles are included” is included in the content information, it is optimal to include “subtitle settings input” in the output setting to the TV receiver 30.

  After determining the output setting from the BD recorder 10 to the TV receiver 30 and the AV receiver 20 in this way, in step S4 (fourth step) in FIG. 5, as shown in FIG. 151, the content information (program information) 152, information 153 relating to the reproduction performance of video and audio as attribute information of the acquired TV receiver 30 and AV receiver 20, and the determined TV receiver 30 and AV The video and audio output settings to the receiver 20 are stored in the storage unit 150 every time content is recorded. In FIG. 7, the acquired information 153 regarding the reproduction performance of the TV receiver 30 and the AV receiver 20 is the same for two contents (contents 1 and 2). The storage unit 150 also stores EPG information 155 acquired by the communication processing unit 162.

  Note that the output settings such as the screen setting and the audio output setting shown in FIG. 6C are merely examples. For example, as the video output setting, deep color (auto / off) of the TV receiver 30 or progressive mode (automatic) / Video), still mode (automatic / field / frame) may be determined, and as audio output settings, delay time settings and level settings for each channel, DTS [registered trademark] (automatic / PCM), AAC [registered] Trademark] (automatic / PCM), dynamic range control (on / off), etc. may be set. Furthermore, language settings (original / Japanese / English / other languages), viewing restrictions (unrestricted / viewable age setting = age input), etc. may be determined as output settings other than video and audio settings.

  Therefore, in the present embodiment, information regarding video and audio reproduction performance is acquired as attribute information of the TV receiver 30 and the AV receiver 20 connected to the BD recorder 10, and information regarding the acquired reproduction performance and content information (program) are acquired. And the output setting to the TV receiver 30 and the AV receiver 20 are determined so as to appropriately correspond to the reproduction of the content to be reproduced, for example, the resolution included in the content information is the SD (Standard Definition) specification. Even so, it is possible to display the HD (High Definition) specification video of the TV receiver 30 while adding the noise reduction function, and to output the sound that demonstrates the 5.1ch surround sound performance of the sound surround device 40. is there.

  Here, since the content management unit 165 automatically determines the output setting to the TV receiver 30 and the AV receiver 20 so that the reproduction of the content becomes more appropriate, the user (viewer) can determine the content of the content and the TV reception. It is not necessary to accurately grasp the playback performance of the device 30 and the AV receiver 20, and it is not necessary for the user to operate the remote control device in accordance with the playback performance of the connected external device. Can be played back by voice.

  Furthermore, compared with the case where the output setting to the external device is uniquely determined as the output setting at a specific time point (when recording or recording reservation) as in the past, the output setting matches the playback performance of the external device. It is possible to determine with certainty.

  In addition, as shown in FIG. 6, the video format (480i 4: 3) of the content information (program information) 152 and the screen information (1080i 16: 9) of the information 153 relating to the reproduction performance of the TV receiver 30 are video. Although it overlaps in terms of information, the contents of the information do not match each other, but the screen information (1080i 16: 9) relating to the reproduction performance of the TV receiver 30 is prioritized and output setting to the TV receiver 30 (resolution) And the size of the video screen) is determined to be 1080i 16: 9, so that the playback performance of the TV receiver 30 can be maximized and the video of the content can be played back.

(Modification)
8 and 9 show content information (program information), information on reproduction performance as attribute information of the TV receiver 30 and AV receiver 20, and modifications of these output settings to external devices.

  In the modification shown in FIG. 8, the difference from FIG. 6 is that the information regarding the audio reproduction performance of the AV receiver 20 is “7.1ch surround” as shown by the thick line in FIG. This is a point that coincides with “7.1ch surround” of the included audio format.

  Therefore, in the modified example of FIG. 8, the content management unit 165 determines the output setting to “7.1ch surround” in accordance with the audio reproduction performance of the AV receiver 20, as shown in FIG. Playback content is optimally pronounced with 7.1ch surround sound. Therefore, the user does not need to perform a remote control operation so that the reproduced sound is optimized in accordance with the sound reproduction performance of the AV receiver 20.

  In the modification shown in FIG. 9, the difference from FIG. 6 is that the video format (resolution / size of the display screen) of the content information (program information) is different as shown by the thick lines in FIGS. 1080p / 16: 9, and the resolution of information relating to the reproduction performance of the connected TV receiver 30 and the size of the display screen are 480i / 4: 3.

  In this modification, even if the video format of the content information (program information) is HD (High Definition) specification, the playback performance of the TV receiver 30 is SD (Standard Definition) specification, so The output setting is set to 480i / 4: 3 by converting (down-converting) the video signal. Therefore, also in this modification, based on both the content information (program information) and the information related to the reproduction performance of the external device (TV receiver 30), the reproduced content is reproduced as video more appropriately as much as possible. Since the output setting (480i / 4: 3) to the TV receiver 30 is determined, an appropriate video can be provided to the viewer when reproducing the content.

  As described above, as can be seen from the embodiment and the two modifications, in the present invention, the reproduction performance of the TV receiver 30, the AV receiver 20, and the audio surround device 40 connected to the BD recorder 10 is not limited. Information regarding the reproduction performance of the connected external device is acquired, and the output setting that makes the best use of the reproduction performance of the external device is automatically determined. Therefore, as compared with the conventional case where the matching data table is used to set the output to an external device whose reproduction performance is known in advance, the reproduction performance of the connected external device is whatever. It is possible to reproduce the content with more appropriate video and audio.

(Operation during playback)
Next, the operation of the content management unit 165 when reproducing content recorded on a BD or the like will be described.

  FIG. 10 shows the operation of the content management unit 165 during content playback. At the time of reproduction, the contents of FIG. 7 stored in the storage unit 150 at the time of recording are referred to.

  Specifically, in step S1 in the figure, when the reproduction target content designated by the user (viewer) with the remote control device 110 is reproduced, for example, when the content 1 in FIG. The associated output setting 1 is read from the storage unit 150. If the content of the output setting 1 is, for example, the output setting 154 shown in FIG. 6, the resolution is set to 1080p and the display screen size is set to 16: 9 as the video setting for the TV receiver 30. The noise reduction setting is set to “ON”, the super-resolution setting is set to “ON”, the subtitle setting is set to “ON”, and 5.1 channel surround setting is performed as an audio output setting for the AV receiver 20.

  Therefore, when the content is reproduced, the output setting stored in the storage unit 150 in association with the reproduced content is read out, the video signal is output to the TV receiver 30 with the output setting, and the audio signal is output to the AV receiver 20. Since it is output, it is not necessary to acquire the current external device settings (output parameters) (output parameters) or to collate the settings with the matching data table as before, making playback content more appropriate quickly and without waste. It can be played back with video and audio.

  After the reproduction content is started to be reproduced with the output setting stored in the storage unit 150 in this way, the viewer sets the output setting of the TV receiver 30 and the AV receiver 20 using the remote control devices 310 and 200 in step S2 of FIG. It is determined whether or not. If the output setting is not changed as a result of the determination, the output setting stored in the storage unit 150 is maintained. If the output setting is changed, for example, the viewer can control the remote control device of the TV receiver 30. When the subtitle setting is changed from “ON” to “OFF” in 310, the BD recorder 10 receives the change of the output setting from the TV receiver 30 or the AV receiver 20 via the HDMI cables 22 and 21. Then, in the next step S3, the output setting of the content to be reproduced is updated in accordance with an instruction from the operator through a remote control operation and stored in the storage unit 150.

  Accordingly, when the output setting for the TV receiver 30 or the AV receiver 20 is changed by the remote control operation of the viewer, the output setting is updated and stored in the storage unit 150, so that the same content is reproduced next time. In this case, the video signal and the audio signal are output with the output setting updated at the previous reproduction. Therefore, when the same content is reproduced next time, the optimum video and audio reflecting the viewer's preference and commitment are obtained, so that the viewer does not need to perform the remote control operation again.

(Second Embodiment)
Next, a second embodiment of the present invention will be described.

  In the first embodiment, each time a content is recorded, the output setting to the TV receiver 30 and the AV receiver 20 is uniquely set based on the information on the content and the information on the reproduction performance as the attribute information of the external device. Although determined, in this embodiment, the output setting that has already been stored is used.

  FIG. 11 is a flowchart showing the operation of the content management unit 165 at the time of recording in this embodiment. In the same figure, the program information of the content to be recorded and the information regarding the playback performance of the current external device are acquired in steps S1 and S2 as in FIG. 5 of the first embodiment. In step S3, the acquisition is performed. It is determined whether or not there is content in the storage unit 150 having program information similar to the program information of the recorded content.

  If content having similar program information has already been stored, in step S4, information related to the reproduction performance of the external device stored in association with the content having similar program information and the external device are stored. Are read out from the storage unit 150 and acquired in step S5. In step S5, information related to the playback performance of the current recording target content and information related to the playback performance of the external device associated with the content having the similar program information If they are not identical (in the case of NO), as in step S3 of FIG. 5 of the first embodiment, in step S6, appropriate external devices (TV receiver 30 and Each output setting to the AV receiver 20) is independently determined. In step S7, the output setting to the external device having the similar program information and the information related to the reproduction performance of the external device (hereinafter referred to as similar content) is associated with the current recording target content. Determined and adopted as output setting to equipment. In step S8, the storage unit associates the output setting to the adopted external device, the acquired program information, and the information relating to the reproduction performance as the attribute information of the current external device in association with the current recording target content. 150.

  Therefore, in this embodiment, as shown in FIG. 12, for example, when the content to be recorded has program information X and information 1 regarding the reproduction performance of the external device, the program information X stored in the storage unit 150 When the program information X of the recording target content is similar to the program information 4 of the content 4 in the storage unit 150 when the similarity is determined to be similar to the program information of the contents 1 to 4... Of the external device associated with the recording target content. If the information 1 regarding the reproduction performance and the information 1 regarding the reproduction performance of the external device associated with the similar content 4 are the same, the content management unit 165 sets the output setting of the similar content 4 as the output setting of the recording target content. 4 is stored in the storage unit 150 in association with the content to be recorded.

  Therefore, in this embodiment, since the output setting associated with similar content is used as the output setting to the external device associated with the newly recorded content, the output setting to the external device where content playback is more appropriate can be simplified. Can get to.

  In addition, when the output setting to the external device associated with the similar content is used and the output setting is updated by the viewer's remote control operation, the viewer can play the newly recorded content. It is possible to obtain optimal video and audio in consideration of the viewer's preference and commitment without requiring remote control operation again. Therefore, in the specific example shown in FIG. 12, program information, information related to the reproduction performance of the external device, and output settings to the external device are stored as items associated with the content. The presence / absence information on whether or not the output setting is updated by the operation of the (viewer) remote control device 110 is also stored in association with each other, and the content having the update “present” information is extracted as similar content. A configuration may be used in which only the output setting is used as an output setting associated with the recording target content.

(Similarity judgment of program information)
In the present embodiment, since the content management unit 165 has similar content to the recording target content and program information and the same information (attribute information) related to the reproduction performance of the external device, it is important to determine the similarity of the program information. It is.

  The similarity determination of program information will be described with reference to FIG. In the figure, priorities are assigned to a plurality of items constituting program information, and one of the plurality of contents is specified as similar contents.

  Specifically, in the figure, the priority is set higher in the order of “title”, “genre”, “video format”, “audio format”, “viewing restriction”, “subtitle setting”. The reason why “title” and “genre” are high in priority is that if they are the same, the connected external devices (TV receiver 30 and AV receiver 20) are likely to be operated with the same output setting. It is.

  In FIG. 13, the “title” of the new content to be recorded is different from the “program name” of the content 2, 3, 4 stored in the storage unit 150, but the stored content 3, 4 and the second and third Since the items of “genre” and “video format” in the priority order match, the two contents 3 and 4 are candidates for similar contents. However, since the “audio format” of the fourth priority order of the recording target content is 5.1ch surround, the content 4 having the same “audio format” is specified as the similar content. Therefore, in the example of FIG. 13, the content 4 that matches the recording target content in the first to fourth priorities and has high similarity is selected and specified.

(Modification of analogy judgment)
FIG. 14 shows a modification of analogy determination of program information. In the figure, a predetermined priority is given to a plurality of items constituting program information, and one similar content is specified.

  In FIG. 14, as shown in the figure, each item constituting the program information is weighted, and the weight values are “10” for “title”, “7” for “genre”, and “5” for “video format”. "," "Audio format", "4", "View restriction", and "Subtitle setting" are each assigned "1".

  Therefore, in the figure, for the program information of the content to be recorded, the contents 2 to 4 recorded in the recording unit 150 have no content that matches in the items of “title” and “genre” (= movie). The contents 2 match in the item “audio format” (= 5.1ch surround), and the contents 3 match in the items “video format” (= 1080p 16: 9) and “audio format” (= 5.1ch surround). The content 4 matches in the items of “video format” (= 1080p 16: 9), “viewing restriction”, and “subtitle setting”. Accordingly, when the matching items are weighted with the weight value, the similarity (total weight value) is “4” for content 2, “9” for content 3, and “7” for content 4, and the similarity is the highest value. Content 3 is identified as similar content. Therefore, in the example of FIG. 14, there is no content whose “title” and “genre” (= movie) match with the recording target content, but “genre” is a “drama” similar to the “movie” of the recording target content. The highly similar content 3 having the same “video format” (= 1080p 16: 9) and “audio format” (= 5.1ch surround) is identified as the similar content.

  FIG. 15 shows another specific example of analogy determination when each item of program information is weighted in the same way as FIG.

  In the figure, for the program information of the content to be recorded, there is no content whose “title” matches in the content 2 to 4 recorded in the recording unit 150, but only the content 2 is “genre” (= music). , Content 3 matches in “audio format” (= stereo audio), and content 4 has no matching item. Therefore, when the above items are weighted, the similarity is “7” for content 2, “4” for content 3, and “0” for content 4. Therefore, also in this specific example, the content 2 that matches the recording target content and the item “genre” (= music) and has a high similarity is selected and specified as the similar content.

  In the similarity determination using the weights of FIGS. 14 and 15, the weight values given to the items of the program information as shown in these figures are examples. In addition, the weight value of each item may not be a fixed value. For example, the user (viewer) operates the remote controller 110 of the BD recorder 10 to set the weight path of a specific item to a large value. You may comprise so that a value can be set variably.

  Further, for example, an item “name” of the user who instructed recording may be included in the content information (program information). And if the weight value of the “name” of the user is set to be large, the content that matches the “name” in the program information of the new recording target content is likely to be identified as similar content. Output settings to external devices (TV receiver 30 and AV receiver 20) that reflect their own preferences and preferences can be obtained automatically, and remote control operation to obtain optimal playback video and audio can be eliminated.

(Third embodiment)
Next, a third embodiment of the present invention will be described. In the second embodiment, the output setting to the external device associated with the similar content is used. However, in this embodiment, as much as possible even when the recorded content is deleted from the recording unit 150. In order to be able to use the output setting of similar contents, the output setting is not deleted but is stored as it is.

  Specifically, in FIG. 16, the recording unit 150 stores four contents, program information associated with each of the contents, information on reproduction performance of the external device (attribute information), and output setting to the external device. In this case, when the operator tries to delete the contents 1 and 2 using the remote control device 110, normally, the contents 1 and 2 and the program information 1 and 2 associated therewith, the external The information 1 regarding the playback performance of the device and the output settings 1 and 2 to the external device are also deleted from the storage unit 150. However, in this embodiment, only the content itself (main part) 1 and 2 instructed to be deleted is deleted. The program information 1 and 2, the information 1 related to the reproduction performance of the external device, and the output settings 1 and 2 to the external device are stored in the storage unit 150 as they are surrounded by the broken lines in FIG. .

  Note that the content management unit 165 deletes only the content when instructing to delete the recorded content, and stores the related program information, information regarding the reproduction performance of the external device, and the output setting to the external device as they are. The user (viewer) receives an instruction signal for operating the remote control device (selection means) 110 of the BD recorder 10 as to whether the related information such as the related program information is to be deleted at the same time. The operation to select is performed.

  Therefore, in this embodiment, the program information 1 and 2 associated with the contents 1 and 2 to be deleted, the information 1 regarding the reproduction performance of the external device, and the output settings 1 and 2 to the external device are stored as they are. When a new content is recorded, the stored program information 1 and 2 and the information 1 related to the reproduction performance of the external device are searched for whether the content is similar to the recording target content. As a result, even if the contents themselves 1 and 2 are deleted from the recording unit 150, the output settings 1 and 2 can be candidates for use as the output settings of the content to be recorded, so that the content can be reproduced more appropriately. As the output setting, it is possible to select a highly accurate output setting that more appropriately reflects the user's (viewer) 's preference and commitment.

  Furthermore, since the content itself (main part) having a larger capacity than the program information and the information related to the reproduction performance of the external device is deleted from the storage unit 150, the storage space of the storage unit 150 can be expanded.

(Fourth embodiment)
FIG. 17 shows a fourth embodiment of the present invention. In the present embodiment, related information such as program information stored in association with content is further added.

  In FIG. 17, the storage unit 150 stores program information and information (attribute information) related to the playback performance of the external device in relation to the content, as in the first embodiment. The difference is that a plurality of types (two types in the figure) of output settings 154 and 157 are stored as output settings. Selection information for selecting one of the two types of output settings, for example, time zone information 158, is added to the content in which the two types of output settings 154 and 157 are stored.

  Specifically, information indicating that output setting 1 is selected during the daytime period and output setting 2 is selected during the nighttime period is stored as the time zone information for content playback. In the output setting 1, “dynamic range control” is set to “OFF” and the volume setting of the audio surround device 40 is set to “high” as the output setting to the TV receiver 30 corresponding to the daytime period. In the output setting 3, as the output setting to the TV receiver 30 corresponding to the night time zone, “Dynamic Range Control” is set to “ON” to limit the loud volume, or the volume setting of the audio surround device 40 is set. Setting is set to “Small” and settings for enjoying TV and music quietly are stored.

  Therefore, in the present embodiment, since the content playback time zone information is also stored in relation to the content, the output setting to the external device is set to an output suitable for the playback time zone according to the content playback time zone. Since it can be set, video and audio can be played back with optimal output settings that match not only the user's (viewer's) preferences and preferences, but also the surrounding environment during content playback.

(Fifth embodiment)
Subsequently, a fifth embodiment of the present invention will be described. In the present embodiment, the playback performance of the connected external devices (the TV receiver 30 and the audio surround device 40) differs depending on whether the content is recorded or played back.

  FIG. 18 shows a configuration of a recording / playback system including a BD recorder in the present embodiment. In this figure, the AV receiver 20 is connected to the BD recorder 10 and the TV receiver 30 is connected to the AV receiver 20 in the same way as in FIG. 1, but a 5.1ch audio surround device is used for recording a predetermined content. 40 shows a situation in which a 7.1ch audio surround device 50 is newly connected instead of the 5.1ch audio surround device 40 when the recorded content is reproduced.

  FIG. 19 shows program information 152 at the time of recording content, information (attribute information) 153R and output setting 154R regarding the playback performance of external devices (TV receiver 30 and audio surround device 40) at the time of recording under the above circumstances. And information (attribute information) 153P regarding the reproduction performance of the external device (TV receiver 30 and audio surround device 50) during reproduction and output setting 154P to the external device. Note that the program information, the information related to the reproduction performance of the external device, and the specific contents of the output setting to the external device are the information 153R related to the reproduction performance of the external device, the audio information in 153P, and the output setting 154R to the external device. , Except for the audio output setting in 154P, is the same as FIG. 9 described in the first embodiment.

  The operation of the content management unit 165 will be described with reference to the flowchart of FIG. In the figure, at the time of content reproduction, in step S1, information 153R relating to the reproduction performance of the external device stored in association with the reproduction target content is read from the storage unit 150 and acquired by the HDMI control unit 130 in step S2. Information 153P related to the reproduction performance of the external device at the current time (reproduction time) is fetched.

  Thereafter, in step S3, the information 153R relating to the reproduction performance of the external device at the time of the recording and the information 153P relating to the reproduction performance of the external device at the time of reproduction are compared. If the audio surround device 40 of 1 ch remains, the recording output setting 154R associated with the playback target content is read from the storage unit 150 in step S4, and the external device is read with the read output setting 154R in step S5. Output setting to (TV receiver 30 and audio surround device 40) is performed.

  On the other hand, if the information regarding the reproduction performance of the external device is not the same in step S3, that is, if the audio surround device is changed to the 7.1ch audio surround device 50, in step S6, it is first associated with the content to be reproduced. After reading the program information 152 and the output setting 154R to the external device at the time of recording from the storage unit 150, in step S7, the read program information 152 and the acquired information related to the reproduction performance of the external device at the time of reproduction Based on 153P, the output setting 154R at the time of recording is corrected. Specifically, as shown in FIG. 19, since the audio information (5.1ch surround) in the information 153R regarding the playback performance of the external device at the time of recording is changed to 7.1ch surround at the time of playback, content management is performed. In consideration of the fact that the audio format in the program information 152 is 7.1ch surround, the unit 165 reproduces the audio output setting (5.1ch surround) in the output setting 154R at the time of recording changed to 7.1ch surround. A time output setting 154P is created. Then, the acquired information 153P regarding the reproduction performance of the external device at the time of reproduction and the newly corrected and determined output setting 154P at the time of reproduction are stored in the storage unit 150 in association with the content to be reproduced.

  After that, in step S8, output setting to external devices (TV receiver 30 and audio surround device 50) is performed with the changed and created output setting 154P at the time of reproduction.

  Therefore, in the present embodiment, when playing back content, even when an external device having different attribute information (playback performance) from that at the time of recording is connected, the external device (7. It is possible to reproduce the content with more appropriate audio and video that exhibits the reproduction performance of the 1ch audio surround device 50). Therefore, the user (viewer) can automatically view the content with appropriate audio and video without requiring an operation to change the audio setting from the BD recorder 10 to the AV receiver 20 from 5.1 ch to 7.1 ch surround. .

  In this embodiment, the case where the audio surround device is different between recording and playback has been described. However, another TV receiver having a different playback performance such as a video format by changing the TV receiver 30 is newly connected. Even in such a case, the output setting during recording may be changed in the same manner as described above. In addition, when a device other than the TV receiver or the audio surround device is newly connected for content reproduction, the content management unit 165 replaces the program setting 152 with the program information 152 and the external device during reproduction instead of the output setting 153R during recording. Based on the reproduction performance information 153P, the output setting 153P to the external device at the time of reproduction may be newly created and determined.

  In the above embodiment, the BD recorder 10, the AV receiver 20, and the TV receiver 30 are connected by the HDMI cables 21 and 22. However, each device is connected by wireless HDMI, and video data and audio are transmitted by wireless communication. A configuration for transmitting and receiving data may be employed.

  As described above, the present invention acquires attribute information such as the playback performance of an external device for content, and makes the external device more suitable for content playback based on the attribute information and information related to the playback content. Therefore, the playback content can be played back with more appropriate video and audio that matches the playback performance of the external device without requiring remote control by the user, and can be applied to content recording and playback devices and systems. Is useful.
