As shown in FIG. 2, the display reproduction system (0201) according to the present embodiment is roughly composed of a display device (0202) and a portable media drive device (0203).

  (Description of Display Device) The display device (0202) includes a display unit (0204), a display control unit (0205), an input set value receiving unit (0206), and a display side communication unit (0207). . The display device according to the present invention includes a home television, a display device for a personal computer, and the like.

  (Description of Display Unit) The display unit (0204) receives the signal and displays it. Here, the “signal” refers to a signal including video and audio information generated by playing a portable medium such as a DVD disk by a portable media drive device such as an HDD-DVD recorder. This signal is transmitted from the portable media drive device via the display side communication unit. “Display” means that the signal including the video information is subjected to signal processing, and the video is displayed on the screen of the display device based on the signal including the video information subjected to the signal processing. That means. Specifically, the display unit (0204) indicates, for example, a functional part from an image signal input terminal of a television to a display. Examples of the display include a liquid crystal display, a plasma display, an organic EL display, and a CRT display. The signal input to the image signal input terminal may be an image signal such as an RGB signal, or a signal that has not been decoded yet in an encoded state. In this case, the function of the display unit includes a decoding function and the like.

  (Description of Display Control Unit) The display control unit (0205) performs control according to a set value for acquiring display on the display unit. Here, the “set value” means that the user can adjust the brightness of the screen output from the display of the display device, the light intensity of each color of red, blue, and green, the aspect ratio, etc. It is a numerical value. In addition, numerical values are included so that the user can adjust the frequency characteristics of the sound output from the speaker of the audio output device, which will be described later (for details, see “Description of Audio Output Device”). To do).

  FIG. 3A shows an example of the set value. In FIG. 3A, the set value includes a plurality of display setting items and values for each display setting item set for each display setting item one by one. The display setting item is one of the properties of the screen output from the display device by the display such as “screen contrast” (0301) in FIG. Further, the value for each display setting item is a numerical value of one of the properties of the screen output from the display device by the display. There are a plurality of display setting items (0303). In the display control unit, the set value is obtained as an input set value input by a user in an input set value receiving unit described later and a set value for each medium output from a set value output unit for each medium described later. To get it. The display control unit adjusts the properties of the screen by performing signal processing such as signal amplification processing on the signal output to the display unit based on the value of each display setting item. . In this way, the display control unit controls display on the display unit. (Note that in the setting values shown in FIG. 3A, the display setting item (0303) and the setting item (0304) described in the lower level than the level where each display setting item is described are set for each setting item. Is a value for each of the audio output setting items and the audio output setting items described in the audio output control unit described later, which will be described later.)

  By the way, each display setting item has a setting item No. Is allocated. In this way, each setting item is assigned a setting item No. assigned to each display setting item. This is because the display device can easily accept how many values for each display setting item are designated for which display setting item.

  (Description of Input Set Value Receiving Unit) The input set value receiving unit (0206) receives a set value used for the control as an input set value. Here, what is meant by “accept as an input set value” will be described below. As shown in FIG. 3 (a), there is a range for each display setting item related to the setting value, and the user can set a setting for each display setting item related to the setting value within the range.

In addition, regarding the setting of the value for each display setting item, the display control unit may be configured to set how many times the signal intensity to be output is increased with respect to the gain value of the signal. It doesn't matter. In this way, the value for each display setting item is set. The value for each display setting item is, for example, that a user operates a setting knob or the like given for each setting item in a control panel provided on the display device, or a remote control that operates the display device. This is input by operating a set value setting button or the like provided. By inputting a value for each display setting item, the control panel or the like generates a setting value signal including information about the setting value input by the user. Then, the input set value reception unit (0206) takes the set value signal as an input set value into the display device in a form that can be processed. The above is an example of what is “accepted as an input set value”. An example of the input set value is shown in FIG. As illustrated in FIG. 3B, the setting item number and the value for each display setting item set by the user for the display setting item corresponding to the setting item number are in XML format in the order of the setting item numbers. Those described in the above are input set values. This input set value is transmitted to the display control unit, and is calculated as a set value by the display control unit. The input set value is transmitted to the portable media drive device via a display-side communication unit described later.

  (Description of Display Side Communication Unit) The display side communication unit (0207) is for communicating with the portable media drive device. “Communication” refers to transmission and reception of signals and the like between the display device (0202) and the portable media drive device. More specifically, for example, a display device composed of a digital broadcasting compatible TV and a portable media drive device composed of an HDD-DVD recorder are connected by an HDMI (registered trademark) cable, a USB cable, wireless communication, or the like. The information such as the signal and the input set value is exchanged between the two via the cable. When information from the display device is transmitted to the outside of the display device, the display side communication unit (0207) serves as an outlet for the information. Further, when taking in information from outside the display device into the display device, the display-side communication unit (0207) serves as an entrance for the information. The display-side communication unit may be one that can use the HDMI CEC command system.

  (Description of Output-side Communication Unit) The output-side communication unit (0208) is for communicating with the display device. Since “communication” is the same as that described in the communication unit on the reproduction side, description thereof is omitted. When information from the portable media drive device is transmitted to the outside of the portable media drive device, the output side communication unit (0208) serves as an outlet for the information. Further, when information from outside the portable media drive device is taken into the portable media drive device, the output side communication unit (0208) serves as an entrance for the information. Accordingly, exchange of information between the display device and the portable media drive device is always performed via the display side communication unit and the output side communication unit. Further, the output side communication unit may use an HDMI CEC command system in the same manner as the display side communication unit.

  (Description of Drive Unit) The drive unit (0209) acquires a signal from a portable medium. “Portable media” refers to portable storage media, such as DVD discs, next-generation DVD discs, CD discs, memory cards, and portable hard disk drive media that can be inserted into and removed from the main unit. Etc. Further, the “signal” is the same as that described in the display unit, and thus the description thereof is omitted. The signal acquired by the drive unit (0209) is transmitted to the signal output unit. “Acquisition” refers to capturing information stored in a portable medium as a signal in a form that can be arithmetically processed by an arithmetic processing unit. The drive unit (0209) acquires a media identifier from the portable medium at the same time as acquiring a signal from the portable medium. This media identifier is used to identify each portable medium, which is a name given to each portable medium. As shown in FIG. 4 (a), this media identifier is composed of the date (0401) when information is recorded on the portable medium and recorded on the portable medium in the XML format (0402). Is possible. Further, when the information recorded on the portable medium is a movie work, the media identifier is constituted by the title (0403) of the movie work recorded in the portable medium in the XML format (0404) or the like. Etc. are also possible. For example, in a Blu-ray Disc (registered trademark) which is a kind of portable media, a “disc management ID” is used. The disc management ID is an identification number set for each Blu-ray Disc (registered trademark). This disc management ID is written on the back of the Blu-ray Disc (registered trademark) cartridge, and Blu-ray Disc (registered trademark) with the disc management ID in portable media drive devices that can use Blu-ray Disc (registered trademark). ) Can also be distinguished. In this case, the Blu-ray Disc (registered trademark) can be identified without having to bother to put the Blu-ray Disc (registered trademark) in the portable media drive device. Accordingly, an input device for inputting the disc management ID is provided in the portable media drive device, and the Blu-ray disc (in the portable media drive device) is input to the portable media drive device using the disc management ID input to the input device by a user operation. (Registered trademark) can be identified. In addition, there is a type in which a read-only area is provided in a part of the portable medium, and an identification number for uniquely identifying the portable medium is recorded in the area. These can also be used as media identifiers. The media identifier is acquired by the drive unit (0209), and then transmitted to the setting value holding unit for each medium and the setting value output unit for each medium.

  Two or more drive units (0209) may be provided for one playback system. For example, it can be configured from a plurality of CD / DVD drives. Alternatively, it may be composed of a plurality of types such as a memory card reader / writer and a CD / DVD drive. Further, the drive unit (0209) does not necessarily have to be incorporated in one housing. The drive unit (0209) and the constituent elements other than the drive unit (0209) in the portable media drive device can be configured by separate casings. In this case, any one of the two can be arranged on the network. The network is not limited to a LAN, and may be a WAN.

  (Description of Signal Output Unit) The signal output unit (0210) outputs a signal from the drive unit to the display device via the output side communication unit. As an example, the output is performed with a playback command from the user as a trigger. Here, the reproduction command refers to a PLAY signal generated when a PLAY button provided on a remote control for a portable media drive device or a portable media drive device housing is pressed. The signal output unit (0210) not only outputs the signal to the display device, but also outputs a timing for outputting the setting value for each medium to the display device in the setting value output unit for each medium (0212) described later. A control signal, that is, a trigger signal is output to the set value output unit for each medium (0212) (this point will be described in “Description of Set Value Output Unit for Each Media” described later).

  (Explanation of Media-Specific Set Value Holding Unit) The media-specific set value holding unit (0211) includes a media identifier acquired from the portable medium by the drive unit, and an input set value acquired from the display device via the output side communication unit.

As illustrated in FIG. 4B, the setting value for each medium is a set of the media identifier illustrated in FIG. 4A and the input setting value illustrated in FIG. It is something that was made. “Associate” means to make the one set. “Hold” means storing a plurality of setting values for each medium identifier such as those illustrated in FIG. 4B in a storage device of a portable media drive device. The set value for each medium is transmitted to the set value output unit for each medium according to the signal output from the signal output unit.

  (Explanation of Media-Specific Set Value Output Unit) The media-specific set value output unit (0212) is associated with the media identifier of the portable media from the media-specific set value holding unit according to the signal output from the signal output unit. The setting value for each medium is acquired and output to the display device via the output side communication unit. “According to the signal output from the signal output unit” means immediately after the media-specific set value output unit (0212) receives the trigger signal from the signal output unit. For the trigger signal, the signal, the reproduction command, or the like can be used. “Acquire” is the same as the media identifier of the portable media related to the signal output among the media identifier of the portable media and the plurality of media-specific setting values held in the media-specific setting value holding unit. This means that a setting value for each medium having a medium identifier is found and extracted from the setting value holding unit for each medium. Then, the set value for each medium output to the display device is transmitted to the display control unit, and is calculated and processed by the display control unit as the set value.

  The above is the description of the functional configuration of the display reproduction system in the present embodiment. Next, a functional configuration of a playback system including an audio output device and a portable media drive device in this embodiment, that is, an audio playback system will be described. The functional configuration of the audio reproduction system in the present embodiment is almost the same as the functional configuration of the display reproduction system. FIG. 5 is a functional block diagram of the audio reproduction system in the present embodiment. As shown in FIG. 5, the audio reproduction system (0501) according to the present embodiment is roughly composed of an audio output device (0502) and a portable media drive device (0503).

  (Description of Audio Output Device) The audio output device (0502) includes an audio output unit (0504), an audio output control unit (0505), an input set value receiving unit (0506), and an audio output side communication unit (0507).

  (Description of Audio Output Unit) The audio output unit (0504) receives a signal and outputs the signal. Since “signal” is as described above, description thereof is omitted. This signal is transmitted from the portable media drive device via the audio output side communication unit. “To output sound” means that a signal including the sound information is subjected to signal processing, and a sound is output from a speaker based on the signal including the sound information subjected to the signal processing. The audio output unit (0504) specifically refers to a functional part from an audio signal input terminal of a television to a speaker, headphones, or the like. Examples of the signal input to the audio signal input terminal include a hi-fi stereo audio signal, a monaural audio signal, and a multi-channel surround stereo signal.

  (Description of Audio Output Control Unit) The audio output control unit (0505) performs control according to a setting value for acquiring audio output from the audio output unit. Since the “set value” is as described above, the description is omitted. In FIG. 3A, the set value includes a plurality of audio output setting items and a value for each audio output setting item set for each of the audio output setting items. The audio output setting item is one of the characteristics of the audio output from the audio output device by the audio output, such as the audio output equalizer 32 Hz (0302) in FIG. The value for each audio output setting item is a numerical value of one of the properties of the audio output from the audio output device by the audio output. There are a plurality of audio output setting items (0304). In the audio output control unit, this set value is the input set value input by the user in the input set value receiving unit described later, and the media specific set value output from the media set value output unit described later. Get by getting. Then, the audio output control unit performs signal processing such as amplification processing on the signal output to the audio output unit based on the value for each audio output setting item, so that the nature of the audio Adjust. In this way, the audio output control unit controls the audio output in the audio output unit.

  (Description of Input Set Value Receiving Unit) The input set value receiving unit (0506) receives a set value used for the control as an input set value. Here, an example of a state of processing in the input set value receiving unit of the audio output device according to the present embodiment is shown below. Basically, the processing is almost the same as the processing performed by the input set value receiving unit of the display device described above. As shown in FIG. 3A, there is a range for each audio output setting item related to the set value, and the user can set the value for each audio output setting item related to the set value within the range.

For example, the audio output device has a plurality of audio output setting items as shown in FIG. 3A and a range of values corresponding to each audio output setting item, and the user of the audio output device sets the audio output setting. When setting the sound output equalizer 32 Hz, which is one of the items, the user sets a value between −12 dB and +12 dB. Here, for example, when the user wants to more strongly output 32 Hz sound, a value of +6 or more may be set for the item of the sound output equalizer 32 Hz. In addition, regarding the setting of the value for each audio output setting item, it is possible to set how many times the signal intensity to be output to the audio output unit is increased with respect to the gain value of the signal in the audio output control unit. The configuration may be taken. In this way, the value for each audio output setting item is set. The value for each audio output setting item is input by the same operation as the value for each display setting item described above. By inputting a value for each display setting item, the control panel or the like generates a setting value signal including information about the setting value input by the user. Then, the input set value receiving unit (0506) takes the set value signal as an input set value into the audio output device in a form that can be arithmetically processed. The above is an example of what is “accepted as an input set value”. An example of the input set value is shown in FIG. As illustrated in FIG. 3B, the setting item number and the value for each audio output setting item set by the user for the audio output setting item corresponding to the setting item number are set in the order of the setting item numbers. What is described is the input set value. This input set value is transmitted to the sound output control unit, and is processed as a set value by the sound output control unit. The input set value is transmitted to the portable media drive device via the audio output side communication unit described later.

  The voice output side communication unit (0507) performs the same function as the display side communication unit. The portable media drive device (0503) according to the audio reproduction system is almost the same as the portable media drive device according to the display reproduction system. Here, instead of the display device, the audio output device outputs the input set value to the portable media drive device (0503) via the audio output side communication unit (0507). The portable media drive device (0503) outputs a signal and a set value for each medium to the audio output device instead of the display device.

<Functional configuration of Embodiment 3>

  FIG. 18 shows a functional block diagram of the display reproduction system in the present embodiment. The functional blocks according to the present embodiment are basically the same as the functional blocks of the display reproduction system according to the second embodiment. However, the setting value holding unit for each medium (1801) of the display reproduction system according to the present embodiment further includes a holding unit for each display device (1802) and a translation table holding means (1803). Furthermore, the setting value output unit (1804) classified by media of the display / playback system according to the present embodiment includes a translated setting value output unit (1805) classified by media.

  (Explanation of display device-specific holding means) The display device-specific holding means (1802) includes a media identifier obtained from a portable medium and an input set value received from the display device via the output side communication unit. When associating and holding, a display device identifier for identifying the display device or the display control unit of the display device is acquired from the display device, and further associated and held. The display device identifier is used to distinguish the display device for each manufacturer name or model of the display device. Here, an example of the display device identifier is shown in FIG. As shown in FIG. 19 (a), the display device identifier is composed of a display device manufacturer name (1901) or the like written as XML data (1902) in the storage device or the like of the display device. Is possible. Further, the model name of the display device may be constituted by what is written as XML type data in the storage device of the display device. FIG. 19B shows an example of setting values for each medium held by the display device holding means (1802). As illustrated in FIG. 19B, the media-specific setting values held by the display device-specific holding means (1802) include a display device identifier (1903), a media identifier (1904), and an input setting value (1905). , In one set. The display device-specific holding means (1802) holds a plurality of the above-mentioned media-specific setting values for each media identifier.

  (Description of Translation Table Holding Unit) The translation table holding unit (1803) holds a translation table for translating the set values for each medium between display devices identified by different display device identifiers or display control units of the display devices. To do. “Translate the setting value for each medium between display devices identified by different display device identifiers or the display control unit of the display device” means that the setting value for each medium that can be used for a display device identified by a certain display device identifier Is made available to a display device identified by a different display device identifier. Here, an example of the translation table is shown in FIG. The translation table shown in FIG. 20A is a translation table included in a portable media drive device manufactured by Adenki, that is, the drive device A. In the first column from the left of the translation table illustrated in FIG. 20A, each display setting item relating to a setting value of a display device manufactured by Adenki, that is, display device A, and a range of values for each display setting item Are arranged vertically. For example, in the cell (2001) in the first row, “screen brightness” (2002), which is one of the display setting items of the display device A, and “Range-10” which is a value range for each display setting item. ˜ + 10 ”(2003). In the cell (2004) on the right side, “Bright” (2005) which is one of the display setting items of the display device manufactured by B-lab, that is, the display device B, and a range of values for each display setting item are displayed. A certain “Range −20 to +20” (2006) and a conversion formula “= screen brightness × 2” (2007) from the value for each display setting item of “screen brightness” to the value for each display setting item of “Bright”, Is described. Further, in the cell next to the right side, display setting items having the same properties as those of “screen brightness” and “Bright” in a display device made by another company, a range of values for each display setting item, and display setting thereof are displayed. A conversion formula for calculating a value for each item based on a value for each display setting item of “screen brightness” is described. As described above, each row of the translation table illustrated in FIG. 20A includes, for each display device manufactured by each company, a setting item having the same or similar property, a value range for each setting item, The conversion formula for each setting item is described. The above is an example of a translation table. “Hold” means that the translation table illustrated in FIG. 20A is stored in a storage device of the portable media drive device in a form that can be processed.

  The translation table can be configured so that the contents can be added. For example, it is assumed that a certain user uses a playback system including the display device A and the drive device A. Here, it is assumed that a manufacturer X who has not manufactured a display device until now manufactures and sells the display device for the first time. Then, it is assumed that the user replaces the display device A with the display device manufactured by the manufacturer X, that is, the display device X and starts using the reproduction system. At this time, in the translation table of the drive device A, the media-specific setting values available for the display device A cannot be converted into the media-specific setting values available for the display device X. Here, the problem as described above can be solved by adopting a configuration in which the contents of the translation table can be additionally written so that the conversion is possible. An example of the configuration is shown below. First, a table for converting the media-specific setting values available for the display device A into media-specific setting values available for the display device X, that is, an AX conversion table is prepared. This A-X conversion table is created by Adenki in response to the display device X being released. This AX conversion table is distributed, for example, by being recorded on a portable medium. The user causes the drive device A to read the portable medium. By the reading, the drive device A acquires an AX conversion table and adds it to the translation table. The AX conversion table may be automatically downloaded to the drive device A through the Internet line. The above is an example of a configuration in which the contents of the translation table can be added.

  (Translated set value output unit for each medium) The translated set value output unit for each medium (1805) responds to the output destination display device or the display control unit of the display device when outputting the set value for each media. The media-specific setting value that is the result of translation using the translation table is output. FIG. 20B shows an example of the state of translation in the medium-specific translated set value output means. In the example shown in FIG. 20B, it is assumed that the user is using the display device B connected to the drive device A. Further, it is assumed that the drive device A has a set value for each medium for the display device A, that is, a set value for each medium A (2008) for a certain portable medium A. First, the portable medium A is about to be reproduced by the drive device A. Here, the media-specific translated setting value output means (1805) acquires the media-specific setting value A from the display device-specific holding means in accordance with the signal output from the signal output unit. Next, a display device identifier is acquired from the display device B. Based on the display device identifier acquired from the display device B, that is, the display device identifier B, the drive device A identifies that the display device connected to the drive device A is manufactured by B-lab. Next, in the translation table, each conversion formula for converting the value for each display setting item of the display device A to the value for each display setting item of the display device B is specified as a translation formula. Then, the value for each display setting item of the media-specific setting value A is converted using the translation formula. What has been subjected to the conversion process in this way is a translated value for each medium (2009). The above is an example of the state of translation in the media-specific translated set value output means. Then, the media-specific translated setting value output means (1805) outputs the media-specific translated setting value (2009) to the display device via the output side communication unit.

  FIG. 21 is a functional block diagram of the audio reproduction system in the present embodiment. The functional blocks of the audio output device (2101) in the present embodiment are basically the same as the functional blocks of the audio output device in the second embodiment. The functional blocks of the portable media drive device (2103) according to the audio reproduction system of this embodiment are basically the same as the functional blocks of the portable media drive device according to the display reproduction system of this embodiment. . However, the setting value holding unit for each medium (2106) according to the sound reproduction system of the present embodiment includes holding means for each audio output device (2107) instead of the holding means for each display device.

  (Explanation of the voice output device-specific holding means) The voice output device-specific holding means (2107) is a portable type that accepts the input set value acquired from the voice output device or the voice output device via the output side communication unit. When storing in association with the media identifier acquired from the media, the audio output device identifier for identifying the audio output device or the audio output control unit of the audio output device is also acquired from the audio output device, and further stored in association with the audio output device identifier. .
