Description

  The present invention relates to a technique for suitably performing audio output accompanying content reproduction.

  2. Description of the Related Art Conventionally, there are provided content playback apparatuses with audio output, such as television receivers and music players. When content is played back on such a playback device, the audio output volume value may be the same as the previous content playback end value, or the default value or user setting value may be used. It is determined. However, the optimum audio output volume value differs depending on various conditions at the time of content reproduction, for example, indoors and outdoors, or the surroundings of a house are under construction.

  Therefore, in Patent Document 1, the sound output volume corresponding to the ambient noise level of the playback device is obtained by updating and acquiring the ambient noise level at the start of playback and during playback with a microphone and determining the change in the noise level therefrom. A technique for reproducing content by value is disclosed.

JP 2007-097087 A

  However, in the above prior art including the technique of Patent Document 1, playback with an optimal audio volume value is not performed immediately after the start of content playback, and the user needs to adjust the volume appropriately after the content is played back. There was a problem. Therefore, for example, content playback at a loud volume suddenly occurred in a quiet hall, causing trouble, or conversely, the playback at the start of playback could not be heard due to noise, and so on. There was a problem.

  In addition to the audio volume value, there are similar problems with, for example, an audio output destination and reproduced audio in audio multiplexed content. That is, the user needs to select the audio output destination as appropriate after the content is played with the external speaker that is the indoor audio output destination selected immediately after starting the content playback outdoors. There was a problem.

  Alternatively, for example, even if the user wishes to reproduce the audio multiplexed content this time in Japanese this time, it was reproduced in English at the time of the previous reproduction, so that the user needs to select the reproduced audio appropriately after the content is reproduced. was there.

  In order to solve the above-described problems, the present invention has a function of adjusting an audio output volume value before reproducing content when an application that reproduces content with audio is used almost simultaneously with activation, such as a TV application. A content reproduction apparatus is provided.

Example 1
<Overview>
FIG. 1 is a conceptual diagram for explaining an example of content reproduction in the content reproduction apparatus of this embodiment. As shown in FIG. 1A, for example, a user touches the screen of a portable television device (content reproduction device) and starts the device in order to view a television program on the go. Then, as shown in FIG. 1B, the television apparatus of the present embodiment displays a volume adjustment GUI screen before displaying the television program on the screen and outputting the sound. And as shown in FIG.1 (c), when a user operates the GUI screen and confirms volume adjustment, it says that the television apparatus of a present Example will perform the display (playback of content) of a television program. Condition.

  As described above, the content reproduction apparatus according to the present embodiment can adjust the audio output volume value before reproducing the content. Therefore, for example, it is possible to prevent the occurrence of problems such as sudden reproduction of content at a high volume in a quiet hall and inconvenience.

<Functional configuration>
FIG. 2 is a diagram illustrating an example of functional blocks in the content reproduction apparatus according to the present embodiment. Note that the functional blocks of the apparatus described below can be realized as a combination of hardware and software. Specifically, if a computer is used, a CPU, a main memory, a bus, or a secondary storage device (a hard disk, a non-volatile memory, a storage medium such as a CD or a DVD, a read drive for the medium, etc.), information Input devices used for input, printing equipment, display devices, other hardware components such as external peripheral devices, interfaces for external peripheral devices, communication interfaces, driver programs for controlling these hardware, Other examples include application programs and user interface applications. Then, by CPU processing according to the program developed on the main memory, the data input from the input device or other interface and held in the memory or hard disk is processed and stored, An instruction for controlling the software is generated. Alternatively, the functional blocks of this apparatus may be realized by dedicated hardware.

  The present invention can be realized not only as an apparatus but also as a method. A part of the invention can be configured as software. Further, a software product used to cause a computer to execute such software and a recording medium on which the product is fixed are naturally included in the technical scope of the present invention (the same applies throughout the present specification). .

  As shown in FIG. 2, the “content playback device” (0200) of this embodiment includes a “start command receiving unit” (0201), a “playback application execution unit” (0202), and a “storage unit”. (0203) and a “volume value changing unit” (0204).

  The “start command receiving unit” (0201) has a function for receiving a start command for starting a playback application, which will be described later, and receives a start command including, for example, various input devices and user interface programs such as GUI and CUI. It can be realized by a program. Specifically, for example, if the content reproduction apparatus has a function of starting a plurality of applications, a mechanism such as an input device or a GUI (graphical user interface) that accepts selection operation input of the application can be used. If the content playback apparatus is configured to automatically start the playback application when the power is turned on, the power-on is accepted as a start command.

  More specifically, “application activation” means that a reproduction application described later is registered in the processing thread of the arithmetic device for execution. That is, reception of various operation commands such as a content playback command that is input after the application is registered in the processing thread of the arithmetic device is not included in “acceptance of an application activation command”.

  The “reproduction application execution unit” (0202) has a function of executing a reproduction application, and can be realized by an arithmetic device such as a CPU or a reproduction application execution program. The “playback application” refers to an application configured to play back the content with audio by the resume process when the execution is started by the received start command. The feature of this playback application is that the content with audio is played back when the execution is started by the start command. That is, this playback application is characterized in that after the activation command is received and the application is started to execute, playback of the content with audio is not executed by clicking a separate playback button or the like provided in the GUI of the application. .

  In other words, the playback application is not a normal application for reproducing a moving image file or an audio file, but includes, for example, a television or radio reception and output display application.

  “Resume processing” refers to processing performed by taking over the processing state at the end of the previous time. Specifically, for example, the audio volume value at the end of the previous time, the audio output destination, and playback for multiplexed audio content. For example, information for identifying a language or the like is held, and audio output processing in that state is performed with reference to the identification information at the next playback.

  The “storage unit” (0203) is a non-volatile storage device and has a function of holding at least an audio output volume value that can be used for the resume process. For example, a flash memory or an HDD (hard disk drive) This can be realized with various storage devices. Specifically, for example, if the volume volume value in the previous reproduction of the content with audio is “25”, the value is stored in the nonvolatile flash memory at the end of the reproduction. Then, when the content with audio is reproduced when the reproduction application is started next time, the audio volume value of the storage unit is referred to.

  The “volume value changing unit” (0204) has a function capable of changing the audio output volume value held in the storage unit before executing the playback application. For example, the “volume value changing unit” (0204) can be executed by an arithmetic unit such as a CPU or a volume value changing program. realizable. The volume value changing unit is configured such that, when a playback application is started by an activation command, the volume volume value can be changed before execution of the content-with-audio reproduction process in the resume process by the activation. And

  That is, as shown in FIG. 1 described above, the volume adjustment GUI screen is displayed on the display before the television program is displayed on the screen and the sound is output by turning on (starting up) the portable television apparatus. In response to an operation input to the GUI screen, the audio volume value for resume processing stored in the nonvolatile storage device is changed from 25 to 15, for example.

  Thus, the volume value changing unit changes the sound volume value of the storage unit which is a nonvolatile storage device. That is, a mechanism for changing the sound volume by changing the voltage of the sound signal using a variable resistor or the like is not included in the volume value changing unit.

  With the above configuration, even if the content playback apparatus plays back the content with audio at the previous volume value by the resume processing as it is when the playback application is started, the audio volume value can be changed before the playback. Can do. Therefore, for example, content playback at a loud volume suddenly occurred in a quiet hall, causing trouble, or conversely, playback may continue without being able to hear the sound at the start of playback in noise. The occurrence of problems can be prevented.

<Hardware configuration>
FIG. 3 is a schematic diagram illustrating an example of a configuration of the content reproduction device when the functional components are realized as hardware. The operation of each hardware component in the resume reproduction process of content with audio will be described using this figure.

  As shown in this figure, the content reproduction apparatus includes a “CPU (central processing unit)” (0301) and a “main memory” (0302). In addition, the CPU executes a predetermined program read into the main memory, so that the functions of the playback application executing unit and the volume value changing unit and various other arithmetic processes can be executed. In addition, the content reproduction apparatus further includes a “flash memory” (0303) that is a storage unit and an “operation panel” (0304) that is an activation command receiving unit. They are connected to each other via a data communication path such as a “system bus” to transmit / receive information and process information. A program is read out to the “main memory”, and the “CPU” refers to the read out program and executes various arithmetic processes according to the procedure indicated by the program. In addition, a plurality of addresses are assigned to each of the “main memory” and “flash memory”, and in the calculation processing of the “CPU”, the addresses are specified and accessed to store the data. It is possible to perform arithmetic processing using.

  Here, when the power-on button of the “operation panel” is operated and the activation command of the content reproduction apparatus is received, the “CPU” reads each program held in the “flash memory” to the “main memory”. Then, the playback application execution program is interpreted, and the playback application held in the “flash memory” is read out to the “main memory” and registered in the processing thread of the “CPU”. Subsequently, the “CPU” interprets the volume value changing program, and displays a GUI screen for changing the volume value on the display before executing the playback application registered in the thread. Become. When a new volume value is input to the GUI screen by an operation input to the “operation panel” and the confirm button or the like is operated, the input volume value is changed to a predetermined volume value write address of “flash memory”. The overwriting process is executed. Then, referring to the sound volume value, the reproduction processing of the content with sound at the sound volume value is executed.

  Further, when a button such as “play without volume change” is operated on the GUI screen, the volume volume value at the end of the previous time held in “flash memory” as it is, for example, “25” is referred to. For example, the reproduction processing of the content with sound at the volume value is executed.

<Process flow>
FIG. 4 is a flowchart showing an example of the processing flow in the content reproduction apparatus of the present embodiment. The steps shown below may be steps executed by each hardware configuration of the computer as described above, or may be processing steps that constitute a program for controlling the computer recorded on a medium. I do not care. As shown in this figure, first, along with the end of reproduction of the content with audio, the audio output volume value that can be used for the resume process is recorded in the nonvolatile storage unit (step S0401). Thereafter, when a start command is received (step S0402), a playback app that is configured to play back content with audio by a resume process in accordance with the start of execution by the received start command is registered in a thread such as a CPU, for example. For example (step S0403). Next, before executing the activated playback application, a volume value changing GUI capable of changing the audio output volume value is displayed, and the input of the audio volume value is awaited. When the audio volume value is input (step S0404), the volume volume value recorded in the non-volatile storage unit is updated (step S0405), and the content with audio is reproduced with the updated volume volume value. The playback application is executed (step S0406).

<Brief description of effect>
As described above, even if the content playback apparatus according to the present embodiment is a content playback apparatus in which the content with audio is played back as it is by the start of the playback application, the audio volume value can be changed before the playback. it can. Therefore, for example, content playback at a loud volume suddenly occurred in a quiet hall, causing trouble, or conversely, playback may continue without being able to hear the sound at the start of playback in noise. The occurrence of problems can be prevented.

The present embodiment relates to a playback apparatus for content with audio as in the first embodiment, and has the following features. In other words, when the previous playback of the content with audio has been terminated by the output of the earphone, the audio output destination selection screen is displayed before the start of the current content playback. For example, when the user selects the built-in speaker output instead of the earphone output, the content reproduction apparatus according to the present embodiment executes the content reproduction based on the audio output from the built-in speaker instead of the resume output from the earphone. .

  As described above, the content reproduction apparatus according to the present embodiment can appropriately select an audio output destination before reproducing the content.
