The configuration of the BD recorder 1 will be described. FIG. 1 is a block diagram illustrating a configuration example of the BD recorder 1. As shown in FIG. 1, the BD recorder 1 includes a broadcast receiving unit 11, a signal processing unit 12, an OSD (On Screen Display) processing unit 13, a control unit 14, an optical disk drive 15, a storage unit 16, an input unit 17, an HDD ( Hard Disk Drive) 18, network I / F 19, and HDMI communication unit 20. The BD recorder 1 is HDMI-connected via the HDMI cable 2 so as to be communicable with the television device 3. The BD recorder 1 is connected to an external antenna AT.

  The broadcast receiving unit 11 is connected to an external antenna AT, and performs digital broadcast tuning, amplification, demodulation, and the like. The broadcast receiving unit 11 is configured to include a digital tuner, an error correction unit, and the like. The digital tuner generates a baseband signal and demodulates the generated baseband signal, and the error correction unit performs error correction on the demodulated data. Thereby, acquisition of TS (Transport Stream) which is a digital signal of the MPEG2 system is performed.

  The TS is a content (program) audio PES (Packetized Elementary Stream), video PES, and additional information divided into fixed-length TS packets and connected. The TS is given to the signal processing unit 12 and converted into a video / audio signal. When performing DR recording in which TS is not directly converted but directly recorded on the HDD 18, the signal processing unit 12 only performs TS through.

  In the signal processing unit 12, the TS generated by the broadcast receiving unit 11 is input and separated into an audio digital signal and a video digital signal. Specifically, the signal processing unit 12 divides the TS generated by the broadcast receiving unit 11 into TS packets.

  The HDMI communication unit 20 has a port to which the HDMI cable 2 is connected, and performs communication according to the HDMI standard with the HDMI communication unit 37 included in the television device 3 via the HDMI cable 2. In HDMI, video content, audio content, and control signals can be transmitted and received with a single HDMI cable 2. Control signal transmission / reception is defined as CEC (Consumer Electronics Control) in HDMI. In CEC, a vendor command (Vendor Command) that can be set by a manufacturer can be used.

  In the video display system of this embodiment, CEC commands and vendor commands in HDMI-CEC are used for inquiries to external devices (television device 3) and responses. The vendor command can specify an external device by specifying a destination address. When an external device is designated as a destination and receives an inquiry, the control unit of the external device returns a response via the HDMI communication unit. Further, the HDMI communication units 20 and 37 of the respective devices 1 and 3 can transmit and receive CEC commands and vendor commands even when the power is off. For example, the BD recorder 1 can make an inquiry and a response to the television apparatus 3 even when the power of the television apparatus 3 is OFF.

(Configuration of television device)
Next, the configuration of the television device 3 will be described. FIG. 2 is a block diagram illustrating a configuration example of the television device 3.

  The network I / F 39 is a physical interface for connecting the television device 3 to the Internet NT. The network I / F 39 can be connected to, for example, a wired LAN or a wireless LAN.

(Configuration of control unit)
Next, the configuration of the control unit 14 of the BD recorder 1 will be described. FIG. 3 is a block diagram illustrating a configuration example of the control unit 14. As illustrated in FIG. 3, the control unit 14 includes an acquisition unit 141, a display control unit 142, and a setting unit 143 as functional elements.

  The acquisition unit 141 acquires information from an external device, and acquires information from the television device 3 using, for example, a CEC command, a vendor command, or the like.

  The display control unit 142 controls the display unit 38 by transmitting, for example, a CEC command and a vendor command to the television apparatus 3.

  The setting unit 143 changes settings of devices (such as the BD recorder 1 and the television device 3). For example, the setting unit 143 sets the image quality condition of the video content displayed on the display unit 38 for each of the devices 1 and 3 and changes the setting of the image quality condition. That is, the setting unit 143 can change the television setting of the image quality condition set in the television device 3 and the recorder setting of the image quality condition set in the BD recorder 1. More specifically, the acquisition unit 141 performs image quality included in the recorder EDID information of the BD recorder 1 and the television EDID information of the television device 3 based on the input received by the input unit 17 of the BD recorder 1. Change the condition settings. Further, the setting unit 143 causes the television device 3 to transmit the changed television EDID information, and causes the storage unit 16 to store the changed recorder EDID information. The acquisition unit 141 is not limited to this example, and the setting of each image quality condition may be changed based on the input received by the television apparatus 3 (for example, the input unit 36). The “television setting” and the “recorder setting” in the present embodiment are examples of the “first setting” and the “second setting” in the present invention, respectively.

(Change of image quality setting)
Next, processing for changing the setting of the image quality condition of content will be described. FIG. 4 is a flowchart for explaining an example of a method for reproducing the content by changing the setting of the image quality condition. Note that FIG. 4 illustrates video content as an example of content, and describes a case where resolution and dynamic range (HDR compatible) settings are changed as image quality conditions.

  First, when an optical disc such as a BD disc is inserted into the optical disc drive 15 of the BD recorder 1 (S101), the acquisition unit 141 acquires television EDID information and television device information from the television apparatus 3 via CEC. (S102), these are stored in the storage unit 16.

  The television EDID information of the television device 3 can be acquired by, for example, the sequence shown in FIG. FIG. 5 is an example of an information acquisition sequence via the CEC when acquiring the television EDID information. FIG. 5 illustrates a case where the television EDID information including the resolution information set in the television device 3 and the dynamic range information is acquired. The resolution information indicates the set value of the resolution of the video content. The dynamic range information indicates the setting of the dynamic range of the video content. For example, it indicates whether the setting corresponds to HDR (High Dynamic range) or the setting corresponds to SDR (Standard dynamic Range). . By setting corresponding to HDR, it is possible to display video content in which the ratio between the minimum value and the maximum value of the identifiable signal amplitude (so-called dynamic range) is wider than the normal dynamic range such as SDR.

  In FIG. 5, the command cd1 is transmitted from the BD recorder 1 to the television apparatus 3 to request notification of resolution information set in the television apparatus 3 (sq1). By transmitting the command cd2 from the television apparatus 3 to the BD recorder 1, the resolution information set in the television apparatus 3 is notified to the BD recorder 1 (sq2). Next, the command cd3 is transmitted from the BD recorder 1 to the television apparatus 3, thereby requesting notification of dynamic range information set in the television apparatus 3 (sq3). By transmitting the command cd4 from the television apparatus 3 to the BD recorder 1, the dynamic range information set in the television apparatus 3 is notified to the BD recorder 1 (sq4).

  Next, based on the television EDID information and television device information of the television device 3 and the recorder EDID information and recorder device information of the BD recorder 1, the display control unit 142 displays the television options and the recorder options on the display unit 38. The setting unit 143 changes the recorder setting and the television setting of the image quality conditions of the BD recorder 1 and the television device 3 respectively. 6A to 6D show display examples of screens 381 to 383 for changing the setting of image quality conditions. FIG. 6A shows an example of the image quality condition setting transition screen 381. FIG. 6B shows an example of the resolution setting screen 382 according to the first embodiment. FIG. 6C shows an example of a warning display when the setting condition of the resolution of the television apparatus 3 does not include the recorder setting set in the BD recorder 1. FIG. 6D shows an example of the dynamic range setting screen 383 according to the first embodiment. 6B to 6D, “Player” represents the BD recorder 1 and “TV” represents the television device 3. In addition, among the display of the television option and the recorder option of the image quality condition, a display having a background color different from that of the display screens 382 and 383 indicates a setting selected based on the input received by the input unit 17. The same applies to FIGS. 7A to 8B described later.

  The display control unit 142 displays the setting transition screen 381 shown in FIG. 6A on the display unit 38 (S103). On the setting transition screen 381, displays m1 to m5 are displayed. The setting unit 143 selects the display m2 to m5 on the setting transition screen 381 based on the input received by the input unit 17, and the television EDID information and the recorder EDID information of the BD recorder 1 and the television device 3 or the television This selection is included in the device information and recorder device information. The display m5 can be selected together with any of the displays m2 to m4.

  The display m1 indicates that the 4K-compatible BD recorder 1 is connected to the television device 3 capable of 4K-compatible and HDR-compatible. The display m2 is a display for the user to select setting of resolution and dynamic range. When the display m2 is selected, as will be described later, the display control unit 142 displays the setting screen 382 (FIG. 6B) and the setting screen 383 (FIG. 6D), and the setting unit 143 sets the resolution and the dynamic range. 3. Change every three. The display m3 is a display for the user to select to set only the dynamic range. When the display m3 is selected, as will be described later, the display control unit 142 displays a setting screen 383 (FIG. 6D), and the setting unit 143 changes the setting of the dynamic range for each of the devices 1 and 3. The display m4 is a display for the user to select not to set the image quality conditions (here, resolution and dynamic range) of each of the devices 1 and 3. When the display m4 is selected on the setting transition screen 381, the setting unit 143 does not change the setting of the image quality condition of the video content. The display m5 is a display for the user to select not to display the setting transition screen 381 after the next time. When the display m5 is selected on the setting transition screen 381, the setting unit 143 indicates in the recorder EDID information or the recorder device information that the processing after S103 in FIG. 4 is not performed when the optical disc is inserted into the BD recorder 1. include. Note that the setting contents related to the display m5 are valid after the next insertion of the optical disc, but can be canceled at any time by other setting processing via the menu screen of the BD recorder 1, for example.

  Next, the setting unit 143 determines whether to change the resolution settings of the BD recorder 1 and the television device 3 based on the input received by the input unit 17 (S104). In the present embodiment, this determination is determined based on whether the display m2 has been selected, or the display m3 or the display m4 has been selected on the setting transition screen 381. If the setting unit 143 determines not to change the resolution setting (NO in S104), the process proceeds to S107 described later.

  If the setting unit 143 determines to change the resolution setting (YES in S104), the display control unit 142 displays the setting screen 382 shown in FIG. 6B (S105). At this time, the display control unit 142 sets the television options (“480p”, “720p”, “2K (1080p)”, and “4K (2160p)”) of resolutions that can be set in the television device 3 and the BD recorder. Recorder options (“480p”, “720p”, “2K (1080p)”, “4K (2160p)”, and “Auto”) with resolutions that can be set to 1 are displayed on the same setting screen 382 of the display unit 38. Let In addition, “480p”, “720p”, “2K (1080p)”, and “4K (2160p)” included in the television option and the recorder option indicate the resolution in progressive (sequential scanning) display, respectively. The numerical part of represents the vertical resolution of the display. In the present embodiment, “Auto” included in the recorder option represents that an optimal setting value based on the recorder device information or a setting value recommended by a manufacturer, for example, is selected. Therefore, the recorder setting when “Auto” is selected is changed to the highest resolution “4K (2160p)” of the BD recorder 1. Note that the present invention is not limited to this example, and in “Auto” included in the recorder option, an optimal setting value based on the television device information and the recorder device information may be selected. For example, the recorder setting when “Auto” is selected may be changed to the highest resolution “2K (1080p)” among the resolutions included in both the television option and the recorder option.

  Based on the input received by the input unit 17 after the setting screen 382 is displayed, the setting unit 143 selects the television setting of the resolution of the television device 3 from the television options, and the resolution of the BD recorder 1 from the recorder options. Recorder setting is selected (S106). The setting unit 143 changes the television setting of the resolution of the television device 3 included in the television EDID information, stores the television EDID information in the storage unit 16, and further passes the HDMI communication unit 20 through the HDMI communication unit 20. The television EDID information is transmitted to the television device 3. Further, the setting unit 143 changes the recorder setting of the resolution of the BD recorder 1 included in the recorder EDID information, and causes the storage unit 16 to store the recorder EDID information. Then, the process proceeds to S107.

  If the television setting and the recorder setting selected in S106 are different, the display control unit 142 displays the display m6 on the setting screen 382. For example, in FIG. 6B, when “2K (1080p)” is selected as the television setting of the resolution of the television device 3 and “Auto” is selected as the recorder setting of the resolution of the BD recorder 1, the BD is set as described above. Since the recorder setting of the recorder 1 is “4K (2160p)”, it is different from the television setting. In such a case, the display m6 informs the user that the television setting of the television device 3 and the recorder setting of the BD recorder 1 are different, and both need to be the same.

  Further, in the setting screen 382, as shown in FIG. 6C, when the television option of the resolution of the television apparatus 3 does not include the same resolution as the recorder setting of the BD recorder 1 (“4K (2160p)” in the present embodiment). The display control unit 142 displays the display m7 on the setting screen 382. The display m7 is a display for prompting the user to connect the display device corresponding to the recorder setting “4K (2160p)” of the resolution set in the BD recorder 1 to the BD recorder 1. In FIG. 6C, the display m7 is also displayed on the setting screen 382 when the recorder setting is “4K (2160p)”.

  Next, the setting unit 143 determines whether or not the television device 3 including the display unit 38 is compatible with HDR based on the television device information and the recorder device information (S107). If it is determined that the television apparatus 3 does not support HDR (NO in S107), the process proceeds to S111 described later. On the other hand, when it is determined that the television device 3 is compatible with HDR (YES in S107), the setting unit 143 determines whether the BD recorder 1 and the television device 3 are based on the input received by the input unit 17. It is determined whether or not to change the HDR compatible setting (S108). In this embodiment, this determination is made based on whether the display m2 or the display m3 is selected on the setting transition screen 381 or the display m4 is selected. If the setting unit 143 determines not to change the HDR-compatible setting (NO in S108), the process proceeds to S111.

  When the setting unit 143 determines to change the HDR compatible setting (YES in S108), the display control unit 142 displays the setting screen 383 shown in FIG. 6D (S109). At this time, the display control unit 142 selects a dynamic range television option (“HDR”, “SDR”) that can be set in the television device 3 and a dynamic range recorder option (“HDR”) that can be set in the BD recorder 1. , “SDR”) is displayed in the same setting 383 of the display unit 38. Based on the input received by the input unit 17 after the setting screen 383 is displayed, the setting unit 143 selects the television setting of the dynamic range of the television device 3 from the television options, and the dynamics of the BD recorder 1 from the recorder options. The recorder setting of the range is selected (S110).
