Description

  The present invention relates to a playback apparatus for playing back a recording medium on which content is recorded.

  In recent years, a reproducing apparatus for reproducing a recording medium such as a Blu-ray Disc (BD: Blu-ray Disc (registered trademark)) has been widely used (see, for example, Patent Document 1). As a Blu-ray Disc standard, a plurality of audio streams (which constitute a plurality of audio data), specifically, a primary audio stream, a secondary audio stream, and an interactive audio stream are recorded on a Blu-ray disc. The primary audio stream is sound data in which primary audio such as audio of the main video is recorded. The secondary audio stream is sound data in which secondary audio such as sub-picture audio in picture-in-picture (PinP) is recorded. The interactive audio stream is sound data in which interactive audio such as a sound effect of a pop-up menu is recorded.

  In such a playback device, the user can switch the audio output mode to either the first audio output mode or the second audio output mode by operating a remote controller or the like. In the first audio output mode, primary audio is output with high sound quality, but secondary audio and interactive audio are not output. In the second audio output mode, primary audio, secondary audio, and interactive audio are mixed and output, but the sound quality of the primary audio tends to be slightly degraded.

  The pickup head unit 101 irradiates the optical disc 40 with laser light and detects reflected light from the optical disc 40. Thereby, the pickup head unit 101 optically reads a plurality of audio streams and video streams recorded on the optical disc 40. When the first audio output mode (described later) is set, the pickup head unit 101 optically reads a primary audio stream among a plurality of audio streams recorded on the optical disc 40. When the second audio output mode (described later) is set, the pickup head unit 101 selects a primary audio stream, a secondary audio stream, and an interactive among a plurality of audio streams recorded on the optical disc 40. Each audio stream is read optically.

  The playback unit 102 includes a first playback unit 102a, a second playback unit 102b, and a third playback unit 103c.

  The first reproduction unit 102a reproduces the primary audio stream by decoding the primary audio stream read by the pickup head unit 101. The first reproduction unit 102 a outputs the reproduced primary audio stream to the audio output unit 103.

  The second playback unit 102b decodes the primary audio stream, the secondary audio stream, and the interactive audio stream read by the pickup head unit 101, thereby mixing (mixing) the primary audio stream, the secondary audio stream, and the interactive audio stream. ) To play. The second reproduction unit 102b outputs the reproduced primary audio stream, secondary audio stream, and interactive audio stream to the audio output unit 103, respectively.

  The third reproduction unit 102c reproduces the video stream by decoding the video stream read by the pickup head unit 101. The third playback unit 102 c outputs the played video stream to the video output unit 104.

  Note that, based on an instruction from the control unit 108, the playback unit 102 sets the first audio output mode (configures the first playback mode; HD Audio output) or the first audio output mode (configures the playback mode) as the audio output mode (configures the playback mode). Two audio output modes (constituting the second playback mode; mixing output) can be executed. The first audio output mode is an audio output mode that is reproduced by the first reproducing unit 102a. The second audio output mode is an audio output mode that is reproduced by the second reproducing unit 102b.

  Note that the sound quality of the primary audio reproduced in the first audio output mode is higher than the sound quality of the primary audio reproduced in the second audio output mode. That is, in the first audio output mode, primary audio is reproduced with high sound quality.

  The audio output unit 103 outputs the reproduced audio stream to the audio output device 20 as an audio signal.

  The video output unit 104 outputs the reproduced video stream to the audio output device 20 as a video signal.

  The HDMI communication unit 105 transmits and receives audio signals, video signals, and the like to and from the HDMI communication unit 203 of the audio output device 20. For example, the HDMI communication unit 105 transmits the audio signal from the audio output unit 103 and the video signal from the video output unit 104 to the audio output device 20 via the HDMI cable 30. Note that transmission of audio signals and video signals by the HDMI communication unit 105 is performed by a TMDS (Transition Minimized Differential Signaling) method.

  The remote control light receiving unit 106 receives a remote control signal from the remote control 50, converts the remote control signal into a remote control code, and outputs it to the control unit 108. For example, when the user operates the remote controller 50, the audio output mode can be set to one of the first audio output mode and the second audio output mode. That is, the remote control light receiving unit 106 accepts an operation for selecting either the first audio output mode or the second audio output mode.

  The storage unit 107 is, for example, an EEPROM (Electrically Erasable Programmable Read-Only Memory). The storage unit 107 stores various data, control programs, and the like. The storage unit 107 stores, for example, whether the current audio output mode is the first audio output mode or the second audio output mode, that is, the playback mode currently selected by the processing unit 181 (described later). Is stored as data indicating either the first reproduction mode or the second reproduction mode. Further, the storage unit 107 stores, for example, genre data set by the user. Genre data is data relating to a user's favorite genre, for example, data indicating cinema, concerts, sports, and the like.

  The genre data is set as follows, for example. FIG. 3 shows a favorite genre setting screen. As shown in FIG. 3, the user operates the remote controller 50 to display the favorite genre setting screen on the monitor 201 of the audio output device 20. The favorite genre setting screen displays a list of a plurality of genres (for example, cinema, concerts, sports, etc.). For example, when the user wants to select cinema as a favorite genre, the cursor is moved to the cinema column by operating the direction key of the remote controller 50 and the enter key of the remote controller 50 is pressed. Accordingly, “cinema” is set as the genre data, and the set genre data is stored in the storage unit 107. Note that a plurality of genre data can be set by selecting a plurality of genres on the favorite genre setting screen.

  The control unit 108 is configured by a microcomputer, for example. FIG. 4 is a block diagram illustrating a functional configuration of the control unit 108. As illustrated in FIG. 4, the control unit 108 includes a processing unit 181, a detection unit 182, and a determination unit 183.

  The processing unit 181 controls the pickup head unit 101, the playback unit 102, the audio output unit 103, and the video output unit 104, respectively. For example, based on a remote control code from the remote control light receiving unit 106, the processing unit 181 instructs the playback unit 102 to perform playback in either the first audio output mode or the second audio output mode. That is, the processing unit 181 selects the first reproduction mode or the second reproduction mode, and instructs the reproduction unit 102 to perform reproduction in the selected first reproduction mode or second reproduction mode. Further, for example, the processing unit 181 superimposes image data for OSD (On Screen Display) display on the video stream decoded by the playback unit 102. The control by the processing unit 181 is executed based on a control program stored in the storage unit 107, for example, triggered by output of a remote control code from the remote control light receiving unit 106. Below, only the function regarding this invention is demonstrated among the some functions which the process part 181 has.

  The detection unit 182 detects the audio reproduction capability of the audio output device 20. Specifically, the detection unit 182 detects whether or not the audio output device 20 is compatible with high-quality HBR audio. The detection unit 182 performs EDID (Extended Display Identification Data) communication with the audio output device 20 via the HDMI cable 30. Accordingly, the detection unit 182 receives the EDID transmitted from the audio output device 20 via the HDMI cable 30. The EDID is information indicating whether or not the audio output device 20 is compatible with high-quality HBR audio (that is, whether or not the audio reproduction capability of the audio output device 20 is compatible with high sound quality). . As will be described later, the processing unit 181 instructs the reproduction unit 102 to perform reproduction based on the result detected by the detection unit 182.

  When the title included in the main content is played, the determination unit 183 determines whether or not the genre information associated with the title matches the genre data set by the user. As will be described later, the processing unit 181 instructs the reproduction unit 102 to perform reproduction based on the result of determination by the determination unit 183.

[Operation of playback device]
Hereinafter, among the various operations performed by the playback apparatus 10, operations 1 to 3 related to the present invention will be described.

<Operation 1>
FIG. 5 is a flowchart showing an operation flow of the playback apparatus 10 when loading of the optical disc 40 is completed. FIG. 6 is a diagram showing a state in which the message box 212 is OSD-displayed on the menu screen 211 when the loading of the optical disc 40 is completed.

  First, when the user turns on the power of the playback device 10, the processing unit 181 displays a menu screen 211 on the monitor 201 of the audio output device 20 as illustrated in FIG. 6. A plurality of icons are displayed on the menu screen 211, and each of the plurality of icons is, for example, an icon for executing content reproduction and an icon for executing environment setting. When the user sets the optical disc 40 on the disc tray of the playback apparatus 10, the optical disc 40 is loaded (S101).

  When loading of the optical disc 40 is completed, the processing unit 181 refers to the storage unit 107 to detect whether the current audio output mode is the first audio output mode or the second audio output mode. That is, the processing unit 181 detects whether the playback mode stored in the storage unit 107 is the first playback mode or the second playback mode. The time when the loading of the optical disc 40 is completed refers to a state from when the execution of loading of the optical disc 40 is completed until the reproduction of the content recorded on the optical disc 40 is started.

  If the current audio output mode is the second audio output mode when loading of the optical disc 40 is completed (YES in S102), the processing unit 181 performs reproduction so as to hold and reproduce the second audio output mode. The unit 102 is instructed (S103). That is, the processing unit 181 selects the second playback mode. Thus, the second playback unit 102b decodes the primary audio stream, the secondary audio stream, and the interactive audio stream, and starts playback by mixing the decoded audio streams (S104).

  If the current audio output mode is the first audio output mode when loading of the optical disc 40 is completed (NO in S102), the detection unit 182 determines whether the audio output device 20 supports HBR audio. It detects (S105). If the audio output device 20 does not support HBR audio (NO in S105), the processing unit 181 instructs the reproduction unit 102 to change to the second audio output mode and reproduce (S106). That is, the processing unit 181 selects the second playback mode. Thus, the second playback unit 102b decodes the primary audio stream, the secondary audio stream, and the interactive audio stream, and starts playback by mixing the decoded audio streams (S104).

  On the other hand, when the audio output device 20 supports HBR audio (YES in S105), the processing unit 181 displays the message box 212 on the menu screen 211 in an OSD manner as shown in FIG. 6 (S107). ). This message box 212 displays a message (warning text) that warns that secondary audio and interactive audio are not output. The message box 212 further displays a message asking the user whether or not to change the audio output mode (displayed as “Audio setting” in FIG. 6). The user can select whether or not to change the audio output mode by operating the direction keys of the remote controller 50 to move the cursor 212a to the left and right and pressing the enter key of the remote controller 50.

  When the user performs an operation to change the audio output mode (YES in S108), the processing unit 181 instructs the playback unit 102 to change to the second audio output mode for playback (S106). That is, the processing unit 181 selects the second playback mode. Thus, the second playback unit 102b decodes the primary audio stream, the secondary audio stream, and the interactive audio stream, and starts playback by mixing the decoded audio streams (S104).

  When the user performs an operation that does not change the audio output mode (NO in S108), the processing unit 181 instructs the playback unit 102 to perform playback while maintaining the first audio output mode (S109). That is, the processing unit 181 selects the first playback mode. Thereby, the first playback unit 102a starts playback by decoding the primary audio stream (S104).

  As described above, in the operation 1, when the audio output mode stored in the storage unit 107 when the loading of the optical disc 40 is completed is the second audio output mode, the processing unit 181 switches to the second audio output mode. The playback unit 102 is instructed to hold and play back. Thereby, when the content in which secondary audio and interactive audio exist is reproduced, the secondary audio and interactive audio can be output. Further, when the audio output mode stored in the storage unit 107 when the loading of the optical disc 40 is completed is the first audio output mode, the processing unit 181 performs the first operation based on the audio reproduction capability of the audio output device 20. The playback unit 102 is instructed to perform playback in either the audio output mode or the second audio output mode. As a result, when the audio output device 20 supports high-quality HBR audio, the primary audio can be reproduced with the best sound quality.

  Note that steps S107 and S108 can be omitted. That is, in step S105, when the audio output device 20 supports HBR audio (YES in S105), the processing unit 181 selects the first playback mode, thereby switching to the first audio output mode. The playback unit 102 may be instructed to hold and play back (S109).

<Operation 2>
FIG. 7 is a flowchart showing the flow of operations of the playback apparatus 10 at the start of title playback. For example, when the title of the content is switched, reproduction of the next title is started (S201). At the start of title reproduction, the detection unit 182 detects whether or not the audio output device 20 is compatible with HBR audio (S202). If the audio output device 20 does not support HBR audio (NO in S202), the processing unit 181 causes the playback unit 102 to play back in the second audio output mode based on the detection result of the detection unit 182. An instruction is given (S203). That is, the processing unit 181 selects the second playback mode.

  When the audio output device 20 supports HBR audio (YES in S202), the determination unit 183 records genre information associated with the title on the optical disc 40 based on a signal from the pickup head unit 101. It is detected whether or not it is performed (S204). When the genre information is not recorded on the optical disc 40 (NO in S204), the processing unit 181 instructs the playback unit 102 to play back in the second audio output mode based on the detection result of the determination unit 183. (S203). That is, the processing unit 181 selects the second playback mode.

  When the genre information is recorded on the optical disc 40 (YES in S204), the determination unit 183 refers to the storage unit 107 to detect whether the user's favorite genre is set as genre data. (S205). If the user's favorite genre is not set (NO in S205), the processing unit 181 instructs the playback unit 102 to play back in the second audio output mode based on the detection result of the determination unit 183. (S203). That is, the processing unit 181 selects the second playback mode.

  If the user's favorite genre is set (YES in S205), the determination unit 183 determines whether or not the genre information associated with the title matches the genre data set by the user. Determination is made (S206). When the genre information and the genre data do not match (for example, when the genre information is “sports” and the genre data is “cinema”) (NO in S206), the processing unit 181 determines the determination unit 183. Based on the determination result, the playback unit 102 is instructed to play back in the second audio output mode (S203). That is, the processing unit 181 selects the second playback mode.

  When the genre information and the genre data match (for example, when the genre information and the genre data are both “cinema”) (YES in S206), the processing unit 181 is based on the determination result of the determination unit 183. The playback unit 102 is instructed to play back in the first audio output mode (S207). That is, the processing unit 181 selects the first playback mode.

  As described above, in the operation 2, when the title of the genre that matches the user's favorite genre is reproduced, the primary audio can be reproduced with the best sound quality. Thereby, the user can enjoy the title of a favorite genre with the best sound quality.

<Operation 3>
FIG. 8 is a flowchart showing an operation flow of the playback apparatus 10 during playback of a title. FIG. 9 is a diagram showing a state in which the message box 215 is OSD displayed on the main video 213 during the reproduction of the title. FIG. 10 is a diagram illustrating a state in which the message box 216 is OSD displayed on the main video 213 during the reproduction of the title.

  The reproduction of the title of the content is started (S301), and the title scene including primary audio, secondary audio, and interactive audio is reproduced (S302). At this time, as shown in FIGS. 9 and 10, the main video 213 and the sub-video 214 in the picture-in-picture are displayed on the monitor 201 of the audio output device 20. The content title includes, for example, a scene in which only primary audio exists, and a scene in which primary audio, secondary audio, and interactive audio exist.

  Based on a signal from the pickup head unit 101 (for example, header information recorded on the optical disc 40 for each title), the processing unit 181 starts playback of a title scene including primary audio, secondary audio, and interactive audio. Detect that. When the processing unit 181 detects the start of scene playback in this manner, the processing unit 181 refers to the storage unit 107 so that the current audio output mode is either the first audio output mode or the second audio output mode. Is detected (S303).

  If the current audio output mode is the first audio output mode (YES in S303), the processing unit 181 prompts to change to the second audio output mode (that is, switches to the second playback mode). The reproduction unit 102 is instructed to reproduce the image data including the message superimposed on the video stream. As a result, as shown in FIG. 9, the message box 215 in which the above message (in FIG. 9, the second audio output mode is “Mixing” and the secondary audio is “secondary audio”) is displayed on the main video 213. On the other hand, the OSD is displayed (S304). The message box 215 further displays a message asking the user whether or not to change the audio output mode. As described in the operation 1, the user operates the direction key of the remote controller 50 to move the cursor 215a to the left and right, and presses the enter key of the remote controller 50 to determine whether or not to change the setting of the audio output mode.

  On the other hand, when the current audio output mode is the second audio output mode (NO in S303), the detection unit 182 detects whether or not the audio output device 20 is compatible with HBR audio (S305). . If the audio output device 20 supports HBR audio (YES in S305), the processing unit 181 prompts to change to the first audio output mode (that is, switches to the first playback mode). The playback unit 102 is instructed to play back the image data including the prompt message superimposed on the video stream. As a result, as shown in FIG. 10, a message box 216 in which the above message (in FIG. 10, the first audio output mode is displayed as “HD Audio”) is displayed on the main video 213 by OSD ( S306). Similar to the message box 215 described above, the message box 216 displays a message asking the user whether to change the audio output mode. As described in the operation 1, the user operates the direction key of the remote controller 50 to move the cursor 216a to the left and right, and presses the enter key of the remote controller 50 to determine whether or not to change the audio output mode. You can choose.
