Description

  The present invention relates to a mobile communication terminal, and more particularly to an improvement of a communication terminal such as a mobile phone that can receive TV broadcast waves and output TV sound.

  In recent years, mobile phones that can receive TV (TeleVision) broadcast waves and display TV images have become widespread. In such a mobile phone, a TV broadcast wave of a channel selected by the user is received, a TV image and TV sound are generated, and screen display and sound output are performed. In general, TV audio obtained from TV broadcast waves may include sub audio in addition to main audio. This sub audio is different from the main audio in language and broadcast content. For example, in a broadcast program such as a news program or a movie program, sub audio that is used in a different language from the main audio is added. There are many cases.

  Conventionally, selection of the main sound and the sub sound has been performed by the user determining whether or not the sound is a desired sound by actually outputting the sub sound and listening to the reproduced sound. For this reason, when the TV sound is switched to a desired sound in accordance with the broadcast program, there is a problem that the user has to switch the TV sound every time the broadcast program is finished or switched to another program.

  A mobile communication terminal such as the above-described mobile phone is usually provided with a function of switching a language used for menu display or the like to a language selected by the user. Therefore, it is convenient if the main voice and the sub voice are automatically switched according to the language selected as the display language by the user. In particular, it is extremely convenient if the voice can be automatically switched to the same language as the language previously selected and designated by the user as the display language.

However, in broadcast programs such as sports programs, sub-sound is added because sub-speech is often added although the broadcast content is different but the language used is not different from the main sound. However, if the TV sound is simply switched to the sub sound, there is a problem that a sound of a language different from the language selected as the display language by the user may be output as the TV sound.

  As described above, in the conventional mobile communication terminal, when the TV sound is switched to a desired sound according to the broadcast program, the user must switch the TV sound every time the broadcast program ends or switches to another program. Therefore, there was a problem that operability was not good. In addition, when TV sound is simply switched according to the presence or absence of sub-sound, there is a problem in that sound in a language different from the language intended by the user may be output.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a mobile communication terminal capable of automatically switching TV sound to desired sound. In particular, an object of the present invention is to provide a mobile communication terminal capable of appropriately switching TV sound according to a language selected by a user as a display language. Another object of the present invention is to provide a mobile communication terminal capable of displaying subtitles in conjunction with TV sound switching.

A mobile communication terminal according to a first aspect of the present invention includes a TV broadcast receiving unit that receives TV broadcast waves and generates reception data of a channel specified by a user, and either main audio or sub audio extracted from the reception data. Voice output means for outputting as a TV voice, user language designation storage means for storing user language designation information for designating a language selected by the user as a user selection language, which is a language used for menu display, Default language designation storage means for storing default language designation information for designating a language, and attribute determination means for determining the presence or absence of the sub-speech having a language different from that of the main voice, based on attribute information extracted from the received data. The audio to be output as the TV audio is based on the user language designation information and the default language designation information, and the main audio or sub audio Constructed and a TV sound determining means for determining any. The TV sound determination means selects the main sound if the user-selected language and the first language match, and if the user-selected language and the first language do not match, the determination result by the attribute determination means Based on the above, either the main voice or the sub voice is selected.

  In this mobile communication terminal, attribute information is extracted from the received data, and the sound to be output as TV sound is determined based on the user language designation information and the default language designation information. At that time, if the user-selected language selected as the language for menu display by the user matches the first language designated by the default language designation information, the main voice is selected. Either main audio or sub audio is selected. With this configuration, when the user-selected language matches the first language, the main voice is selected, and when the user-selected language does not match the first language, the main voice or sub-voice is based on the attribute information. Therefore, the TV sound can be automatically switched according to the language selected by the user as the menu display language.

That is, when there is sub audio, it is determined whether or not the language of the sub audio is different from the main audio based on the genre designation information of the broadcast program. According to such a configuration, when the user-selected language does not match the first language, the main sound or the sub sound is appropriately selected based on the determination result of the presence or absence of the sub sound having a language different from the main sound. Therefore, it is possible to prevent the sound of a language different from the language selected as the display language by the user from being selected as the TV sound. Therefore, even in the case of a broadcast program to which sub audio in the same language as the main audio is added, the TV audio is appropriately selected by determining the language difference between the main audio and the sub audio. It is possible to prevent automatic switching to the secondary audio.

  In the mobile communication terminal according to the third aspect of the present invention, in addition to the above configuration, the default language designation information includes language designation information that designates a language different from the first language as the second language, and the TV audio determination The means is configured to compare the second language and the user-selected language when there is the sub-speech and select the sub-speech based on the comparison result. That is, when the user-selected language does not match the first language and there is a secondary voice, the user-selected language is compared with the second language, and the secondary voice is selected based on the comparison result. Specifically, for example, if the user-selected language matches the second language, the secondary sound is selected, and if the user-selected language does not match the second language, the main sound is selected. According to such a configuration, since the TV sound is appropriately selected based on the comparison result between the user-selected language and the second language, when there are three or more languages that can be selected as display languages, the user can It is possible to prevent the sound of a language different from the language selected as the language from being selected as the TV sound.

  In the mobile communication terminal according to the fourth aspect of the present invention, in addition to the above-described configuration, the TV sound determination means can perform the above identification if the attribute information includes language identification information used for the main sound and sub-audio. One of the main voice and the sub voice is selected based on the identification result of the language based on the information and the user language designation information. According to such a configuration, when the identification information of the language used for the main voice and the sub voice is included in the attribute information, the main voice or the sub voice is based on the language identification result based on the identification information. Is appropriately selected, the TV sound can be automatically switched to the sound in the language selected by the user as the display language.

  A mobile communication terminal according to a fifth aspect of the present invention, in addition to the above configuration, determines whether or not caption information is present based on screen display means for displaying a TV image on the basis of the received data, and on the basis of the attribute information. And subtitle display determining means for determining whether or not to display subtitles on the screen based on the user language specifying information and the default language specifying information. The subtitle display determining means displays the subtitle if the user-selected language and the first language match, and if the user-selected language and the first language do not match, the subtitle display determining means Based on this, it is determined whether or not to display the subtitles. According to such a configuration, the subtitle is displayed when the user-selected language matches the first language, and the subtitle is displayed based on the attribute information when the user-selected language does not match the first language. Therefore, it is possible to display subtitles according to the language selected by the user as the menu display language.

  FIG. 4 is a block diagram showing an example of a functional configuration in the mobile phone 1 of FIG. In addition to the receiver 8 and the transmitter microphone 7 described above, the cellular phone 1 includes antennas 11a and 12a, a cellular communication unit 11, a TV broadcast receiving unit 12, an operation input unit 13, an audio output unit 14, and image generation. 16, an LCD 17, a display language switching unit 18, a user language designation storage unit 18 a, an attribute determination unit 19, and a TV audio determination unit 20, and their operations are controlled by a main control unit 15 including a processor.

  The audio output unit 14 is an output device that outputs audio from the speaker 14a. Normally, the receiver 14 is used in a state where the receiver 8 is close to the ear, whereas the speaker 14a is used in a state where it is separated from the ear. Therefore, the speaker 14a can output a sound having a louder volume than that of the receiver 8 for receiving. This speaker 14a is used as a built-in speaker for outputting a ring tone when receiving a call, outputting a received sound during a call, or outputting TV sound when watching TV.

  When a call is made with the other party's telephone using the speaker 14a, the voice from the other party's telephone is amplified and output from the speaker 14a, and the input signal from the microphone 7 for transmission is amplified. Thus, it is possible to make a so-called hands-free call without holding the mobile phone 1. At this time, the input signal from the transmitting microphone 7 is input to a cancel circuit for preventing howling. Switching between a normal call by the receiver 8 and a hands-free call can be performed by operating the operation keys 4a.

  In the audio output unit 14, TV audio is generated based on the reception data input from the TV broadcast receiving unit 12 via the main control unit 15, and the reproduction sound is output from the speaker 14a. At that time, either the main audio or the sub audio extracted from the received data is output as TV audio.

  The cellular communication unit 11 is a mobile communication processing unit that transmits and receives radio waves to and from the base station via the communication antenna 11a. In a state where a telephone line is established with the other party telephone, a voice signal based on the user's transmission sound is transmitted from the cellular communication unit 11, and a voice signal based on the transmission sound from the other party telephone is transmitted to the cellular communication unit 11. By receiving, the call sound is transmitted and received in real time.

  The TV broadcast receiving unit 12 is a tuner that receives a TV broadcast wave transmitted from a TV station via a TV broadcast receiving antenna 12a. The TV broadcast receiving unit 12 generates reception data including TV images, TV sound, and attribute information. The TV broadcast wave transmitted from the TV station includes an analog broadcast wave corresponding to analog broadcast and a digital broadcast wave corresponding to digital broadcast. The digital broadcast wave received by the TV broadcast receiving unit 12 is a one-segment broadcast wave for a mobile phone assigned to a certain band of a general digital high-definition broadcast wave. In addition to the TV image and TV sound, the TV image Attribute information includes text information such as subtitles corresponding to, and related articles, audio information such as the presence or absence of sub-audio and stereo broadcasting, channel information according to the frequency band of received radio waves, and the like.

  In the TV broadcast wave reception process by the TV broadcast receiver 12, a baseband signal included in a specific frequency band corresponding to the channel selected by the user is extracted and output as reception data.

  Based on the TV broadcast wave received by the TV broadcast receiver 12, a TV image is displayed on the display screen 2a, and a TV sound corresponding to the TV image is output from the speaker 14a to view the TV broadcast. Can do. Further, by extracting the character information included in the TV broadcast wave and displaying it on the display screen 2a, it is possible to display character information such as subtitles together with the TV image. Further, if TV images and TV sounds based on TV broadcast waves are stored in a memory (not shown), TV broadcasts can be recorded.

  The operation input unit 13 performs an operation of generating an input signal based on operations of the operation keys 4a and 5a to 5c. An LCD (Liquid Crystal Display) 17 is an image output device having a display screen 2a. The image generation unit 16 performs an operation of generating image data and causing the LCD 17 to display the screen. Specifically, a standby screen, an incoming screen, an e-mail browsing screen, a menu screen, a TV image, and the like are generated as image data.

  The standby screen is a screen display that is displayed when waiting, and the incoming call screen is a screen display that is displayed when a call or e-mail is received. The e-mail browsing screen is a screen display for displaying header information and mail text of received mail, or for creating and editing an e-mail. The menu screen is a screen display that allows the user to select various functions, control parameters, and the like, and is displayed by, for example, operating the menu key 5a.

  In the image generation unit 16, a TV image is generated based on the reception data input from the TV broadcast reception unit 12 via the main control unit 15, and a reproduced image is displayed on the display screen 2a.

  The display language switching unit 18 performs a process of switching a language used for displaying a menu screen or an e-mail browsing screen based on a user operation. Specifically, when a user selects a desired language from a plurality of languages on a menu screen for selecting a display language, the language is designated as the display language. At that time, user language designation information for designating the language selected and designated by the user as the user selected language is stored in the user language designation storage unit 18a. The image generation unit 16 performs screen display based on the user language designation information, and displays a character string or the like in the user selected language.

  The attribute discriminating unit 19 performs processing for extracting attribute information of the received channel from the received data and generating attribute discriminating information by discriminating the presence or absence of sub-sound based on the extraction result. Here, based on the broadcast program genre designation information included in the attribute information, the attribute determination unit 19 determines the presence or absence of sub-sound that is different in language from the main sound.

  In general, the main voice is a voice in a language mainly used in a language zone (country, region, etc.) to which the transmission source TV station belongs. The secondary audio is audio added by the TV station according to a broadcast program or the like, and the language and broadcast content used are different from the main audio. For example, in a broadcast program such as a news program or a movie program, there are not a few cases in which audio having a language different from that of the main audio is added as sub audio. Specifically, in Japan, Japanese voice is added as the main voice and English voice is added as the sub voice. On the other hand, in broadcast programs such as sports programs, audio in the same language as the main audio may be added as sub audio.

  The genre designation information is additional information added by the TV station in order to divide the broadcast program according to the program content and viewing target. Based on this genre designation information, the category (genre) to which the broadcast program belongs can be determined. For example, it is possible to determine whether a broadcast program being received belongs to a genre of a news program, a movie program, or a sports program. The attribute discrimination unit 19 discriminates the presence / absence of sub-speech having a different language from the main voice based on such genre designation information, so that the language difference between the main voice and the sub-sound can be correctly discriminated.

  The TV sound determination unit 20 performs a process of determining the sound to be output as the TV sound as either the main sound or the sub sound. Specifically, the output voice is determined based on the user language designation information stored in the user language designation storage unit 18a and the language designation information determined by default.

  FIG. 5 is a block diagram illustrating a configuration example of a main part of the mobile phone 1 of FIG. 4, in which details of the TV sound determination unit 20 are illustrated. The TV sound determination unit 20 includes a comparison unit 21, a default language designation storage unit 22, and an output language instruction unit 23. The default language designation storage unit 22 is a nonvolatile memory that stores default language designation information for designating the first language 22a and the second language 22b from among a plurality of languages that can be selected as display languages.

  The default language designation information is language designation information that designates the language associated with the main audio of the TV audio as the first language 22a and the language that is associated with the sub audio and is different from the first language 22a as the second language 22b. is there. Here, the default language designation information is written in the default language designation storage unit 22 at the time of product shipment, and accordingly, the first language 22a and the second language 22b are determined in advance. The default language designation information may be rewritten by a user operation.

  In general, it is considered that the language used for the main voice and the sub voice can be specified if the language area of the country or region where the terminal is used is known. The language specified in this way is designated by default language designation information. Here, it is assumed that there is only one language designated as the first language 22a or the second language 22b. Specifically, for example, Japanese is designated as the first language 22a, and English is designated as the second language 22b.

  The comparison unit 21 compares the user selection language with the first language 22a and the second language 22b based on the user language designation information and the default language designation information, and outputs a comparison result to the output language instruction unit 23. Is going.

  The output language instruction unit 23 determines the output audio based on the comparison result by the comparison unit 21 and the attribute discrimination information, and performs a process of generating a TV audio control signal. Specifically, if the user-selected language and the first language 22a match, the main voice is selected. If the user-selected language and the first language 22a do not match, the main voice or the first language 22a is selected based on the attribute discrimination information. An operation for selecting one of the sub-voices is performed.

  If the user-selected language does not match the first language 22a, the main voice is selected if there is no sub-voice different from the main voice and the language, and the second language 22b if there is a sub-voice different from the main voice and the language. The sub-speech is selected based on the comparison result of the user-selected language. Here, when there is a sub-speech whose language is different from that of the main sound, if the user-selected language and the second language 22b match, the sub-sound is selected, and if they do not match, the main sound is selected. And

  Instead of selecting the main voice when the user-selected language does not match either the first language 22a or the second language 22b even though there is a sub voice whose language is different from the main voice. A secondary sound may be selected.

  In the audio output unit 14, the audio to be output as TV audio is switched based on the TV audio control signal from the output language instruction unit 23. Here, it is assumed that a comparison process based on the language designation information and an output sound determination process based on the attribute discrimination information are performed when the TV broadcast wave reception process starts or when the attribute information changes. Thus, the TV sound can be automatically switched to an appropriate sound in accordance with the end of the broadcast program while watching TV or switching to another broadcast program.

  FIG. 6 is a diagram showing an example of the operation in the mobile phone 1 of FIG. 4, and shows a display screen 2a on which a menu screen for selecting a display language is displayed. In this example, a case where a menu screen is displayed when the display screen 2a is in the landscape state is shown. In this horizontally long state, the display area is expanded in the left-right direction compared to the up-down direction as viewed from the user. In such a horizontally long state, a pictogram (pictogram) display area 31 is provided at the upper end of the display screen 2a, and an icon display area 33 is provided at the lower end. Between the display area 31 and the display area 33 is a menu display or TV image display area 32.

  In the display area 31, there are arranged pictograms indicating the reception intensity of radio waves, incoming e-mails, and the remaining battery level. In the display area 33, icons such as an end icon are arranged.

  In the display area 32 displayed as a menu, identification information of a plurality of languages that can be selected as display languages is displayed in a list 34. In this example, item numbers and language names are displayed as identification information. Specifically, “1. Japanese”, “2. English”, “3. French”, and “Chinese” are displayed, and the user selects and designates a display language from these four languages. be able to. Here, it is assumed that any one of these languages is selected and designated by operating the direction key 5c or the numeric keypad. The language identification information 34a (“1. Japanese”) selected and specified is displayed in reverse video, and a display language switching process is executed by a predetermined key operation.

  FIG. 7 is a diagram showing an example of the operation in the mobile phone 1 of FIG. 4, and shows the display screen 2a after the display language is switched to English. In this example, the menu screen after switching the display language is displayed. When the display language is switched, display of a character string displayed as an icon or a character string indicating identification information is switched.

  Specifically, “1. Japan”, “2. English”, “3. French”, and “4. Chinese” are displayed as identification information of selectable languages, and the identification information of the language that is selected and designated 34b ("2. English") is highlighted.

  FIG. 8 is a diagram showing an example of the operation in the mobile phone 1 of FIG. 4, and shows a display screen 2a on which a TV image is displayed. When the TV is turned on by a predetermined key operation, a TV broadcast wave reception process is started, a TV image is displayed, and TV sound is output. The reproduced image of the TV broadcast wave is displayed in the display area 32 of the display screen 2a, and the TV sound is reproduced from the speaker 14a.

  In the display area 33, a menu icon 33a and an end icon 33b are arranged. The menu icon 33a is an icon associated with the menu key 5a, and the end icon 33b is an icon associated with the end key 5b.

  In this example, a news program “News TV” broadcast by a TV station (channel 2) selected by the user is displayed as a TV image. In broadcast programs such as news programs and movie programs, there are many cases in which sub audio having a language different from the main audio is added as TV audio. In this embodiment, when such sub audio is added to the reception data of the TV broadcast wave, the TV audio is automatically switched according to the language selected as the display language by the user.

  Specifically, if the user-selected language matches the first language 22a specified by default, the voice intended by the user is the same language as the user-selected language, that is, the first language 22a (here, Japan The main voice is output as if the voice was a word). If the user-selected language matches the second language 22b specified by default, the voice intended by the user is the same language as the user-selected language, that is, the voice in the second language 22b (here, English). Sub audio is output. If the user-selected language does not match any of the default-designated languages, the sub-speech is regarded as a voice in a language different from the user-selected language, and here, the main voice is output. . That is, the language used for the secondary audio is estimated based on the default language specifying information and the genre specifying information as the attribute information, and the TV audio is appropriately switched.

  Steps S101 to S108 in FIG. 9 are flowcharts showing an example of an automatic switching operation of TV sound in the mobile phone 1 in FIG. First, the comparison unit 21 compares the user-selected language and the first language 22a, and outputs the comparison result to the output language instruction unit 23 (step S101). If the user-selected language and the first language 22a match, the output language instruction unit 23 instructs the main voice (steps S102 and S108), and ends this process.

  On the other hand, if the user-selected language and the first language 22a do not match, the attribute discrimination information is referred to, and the output voice is instructed based on the presence or absence of the sub-voice having a different language from the main voice (steps S103 and S104). At this time, if there is no sub-sound that is different in language from the main sound, the main sound is instructed, and this process ends. If there is a sub-speech with a different language from the main speech, the user-selected language is compared with the second language 22b, and an output speech is instructed based on the comparison result (steps S105 and S106).

  At this time, if the user-selected language matches the second language 22b, the sub voice is instructed (step S107), and if not, the main voice is instructed.

  According to the present embodiment, the main voice is selected when the user selected language matches the first language 22a, and based on the attribute determination information when the user selected language does not match the first language 22a. Since the main sound or the sub sound is selected, the TV sound can be automatically switched according to the language selected as the display language by the user. In particular, when the user-selected language does not match the first language 22a, the main voice or the sub voice is appropriately selected based on the determination result of the presence or absence of the sub voice that is different from the main voice, so that the user can It is possible to prevent the sound of a language different from the language selected as the display language from being selected as the TV sound. Therefore, even in the case of a broadcast program to which sub audio in the same language as the main audio is added, the TV audio is appropriately selected by determining the language difference between the main audio and the sub audio. It is possible to prevent automatic switching to the secondary audio.

  In the present embodiment, an example in which the language used for the secondary audio is estimated from the default language designation information and the attribute information and the TV audio is automatically switched has been described. However, the present invention is limited to this. It is not a thing. For example, if the attribute information extracted from the received data includes the identification information of the language used for the main sound and the sub sound, the TV sound is based on the identification result of the language based on this identification information and the user language designation information. May be switched.

  Specifically, before the comparison process performed based on the user language designation information and the default language designation information, first, it is determined whether or not the language identification information is included in the attribute information extracted from the received data, TV sound is switched based on the determination result. That is, if the language information is not included in the attribute information, the comparison process is performed, and the TV sound is switched based on the comparison process result. On the other hand, if the language information is included in the attribute information, the language used for the main voice and the secondary voice is identified based on the identification information, and the TV voice is identified based on the identification result and the user language designation information. To switch. For example, the TV sound is switched to the same language as the user-selected language.

  According to such a configuration, when the identification information of the language used for the main voice and the sub voice is included in the attribute information, the main voice or the sub voice is based on the language identification result based on the identification information. Is appropriately selected, the TV sound can be automatically switched to the sound in the language selected by the user as the display language.

Embodiment 2. FIG.
In the first embodiment, the example in which the main sound and the sub sound of the TV sound are automatically switched has been described. In contrast, in the present embodiment, a case will be described in which a caption is displayed based on attribute information regarding the caption.

  FIG. 10 is a block diagram showing a configuration example of a mobile communication terminal according to Embodiment 2 of the present invention. This mobile communication terminal 40 is different from the mobile phone 1 of FIG. 4 in that it includes a caption display determining unit 41. The caption display determination unit 41 determines the presence / absence of caption information based on the attribute information extracted from the received data, and displays the caption on the display screen 2a based on the determination result, the user language designation information and the default language designation information. Processing to determine whether or not to perform is performed.

  In general, broadcast programs such as movie programs often have subtitle information added as character information. A subtitle here is a character string displayed on the display screen 2a corresponding to a TV image, and is added according to a program content or viewing target. Specifically, in Japan, subtitles in Japanese are added. Here, in addition to what is displayed on the TV image, what is displayed in a display area different from the TV image is also referred to as subtitle.

  When such subtitle information is added, the subtitle display determination unit 41 displays subtitles if the user-selected language and the first language 22a match, and the user-selected language and the first language 22a do not match. Then, it is determined whether or not to display the caption based on the determination result by the attribute determination unit 19. That is, if the user-selected language matches the first language 22a, the user-selected language is regarded as the same language as the language used for the caption, and the caption is displayed.

  On the other hand, when the user selected language and the first language 22a do not match, the user selected language is regarded as a language different from the language used for the caption. At this time, the second language 22b and the user-selected language are compared, and the caption is displayed based on the comparison result. Here, if the user-selected language matches the second language 22b, the caption is not displayed, and if the user-selected language does not match either the first language 22a or the second language 22b, the caption is displayed. To do.

  In other words, if the user selects the same language as the language that is estimated to be used for subtitles (Japanese) as the display language, the subtitles are displayed, and it is estimated that they are different from the language used for the subtitles. If the user selects the second language 22b (in this case, English) as the display language, the subtitles are not displayed. Accordingly, subtitles can be displayed according to the language selected as the display language by the user, so that subtitles in languages not intended by the user can be automatically hidden. By not displaying subtitles, it becomes easier to see TV images, or the display area of subtitles can be used for other purposes.

  According to the present embodiment, when the user-selected language matches the first language 22a, the caption is displayed, and when the user-selected language does not match the first language 22a, the caption is displayed based on the attribute information. Since it is determined whether or not to display, subtitles can be displayed according to the language selected by the user as the menu display language.

  In Embodiments 1 and 2, an example in which TV sound is automatically switched has been described, but the present invention is not limited to this. For example, the present invention can also be applied to automatic switching of language settings in a browser that obtains site information by accessing a web server on a communication network such as the Internet.

  Specifically, based on the acquired site information, the presence or absence of link destination information with a different display language is determined, and if there is such a link destination, the link destination in the same language as the user-selected language is accessed. Can be considered. In this way, the display language of the website can be automatically switched to the language selected by the user as the display language.
