  DESCRIPTION OF EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. However, the scope of the invention is not limited to the illustrated examples.

[First Embodiment]
First, the first embodiment will be described.

(Overview)
FIG. 1 is a diagram illustrating an appearance example of the television receiver 1 according to the first embodiment. A television receiver 1 shown in FIG. 1 has an apparatus main body 2 formed in a thin rectangular parallelepiped that is long in the horizontal direction. The apparatus main body 2 is formed in a casing having a length of 61 mm, a width of 99 mm, and a thickness of 24 mm, for example, and can be carried and used. A liquid crystal display panel 3 and a plurality of touch switches SW1 to SW6 are disposed on the front surface of the apparatus main body 2. The liquid crystal display panel 3 is, for example, a TFT (Thin Film Transistor) type liquid crystal display panel having a screen size of 3.0 inches. Further, a mode change switch 5 and a speaker 6 are disposed on the side surface of the apparatus main body 2. Although not shown, a slot for inserting an SD card, an insertion port for an earphone terminal, and the like are disposed on the side surface of the apparatus main body 2. The television receiver 1 receives a television broadcast signal related to terrestrial digital broadcasting, displays and outputs a television broadcast screen (video information) based on the received television broadcast signal on the liquid crystal display panel 3, and outputs audio information from the speaker 6. Output. The television receiver 1 has a built-in BML browser for reproducing content (hereinafter referred to as BML content) described in a broadcast markup language called BML (Broadcast Markup Language). Is received and played.

  The on / off switch SW1 switches on / off of the television viewing by switching the liquid crystal display panel 3 and the speaker 6 on / off. The channel switch SW2 switches a channel to be viewed on the television receiver 1. The volume switch SW3 switches the volume. The brightness switch SW4 switches the brightness of the liquid crystal display panel 3. The up switch SW5 and the down switch SW6 perform channel selection, volume increase / decrease, and brightness adjustment. The up switch SW5 and the down switch SW6 function according to the type of the switch that was pressed immediately before. That is, when the up switch SW5 or the down switch SW6 is pressed after the channel switch SW2, it functions as a channel up switch or a channel down switch for selecting a channel. Similarly, when the up switch SW5 or the down switch SW6 is pressed after the volume switch SW3, it functions as a volume up switch or a volume down switch for increasing or decreasing the volume, and the brightness switch SW4 is followed by the up switch. When the SW5 or the down switch SW6 is pressed, it functions as a brightness up switch or brightness down switch that adjusts brightness by making the screen brighter or darker.

  The mode switch 5 is a switch for switching the mode of the television receiver 1 and is realized by, for example, a slide-type switch. Here, the modes are, for example, an “off” mode in which the power of the television receiver 1 is turned off, an “on” mode that is a television viewing mode in which the television receiver 1 is turned on to perform normal television viewing, There are four types of modes: a “hold” mode that does not accept an operation by a switch, and a “NAVI” mode that is an audio content output mode for reproducing audio guidance as audio content when watching TV, and the user can select one of the four modes. Can be selected and switched.

The “NAVI” mode will be described when the user performs on / off of TV viewing, channel selection, volume increase / decrease, and light / dark adjustment with the switches SW1 to SW6 during TV viewing. In this mode, voice guidance corresponding to the operation content is played.
This voice guidance is reproduced with a predetermined voice set in advance. As the predetermined voice, for example, a voice of a specific voice actor, an idol, a television announcer, or the like can be used.
For this voice guidance, a plurality of voice guidance levels corresponding to the usage level are prepared for each voice guidance level, and the voice guidance level is determined based on the accumulated usage time, unused time, the number of operations, It changes in stages according to usage conditions such as operation frequency. For example, in the following description, the voice guidance level is described as changing in three steps, but the number of steps is not limited to this.

  FIG. 2 is an explanatory diagram for explaining three levels of voice guidance levels. As an example, when the on / off switch SW1 is pressed, the contents of voice guidance reproduced according to the voice guidance levels are shown. ing. Specifically, FIG. 2A shows the voice guidance reproduced at the first stage voice guidance level (hereinafter referred to as “level 1”), and FIG. 2B shows the second stage voice guidance. The voice guidance that is played back at the level (hereinafter referred to as “level 2”) is played back at the third stage voice guidance level (hereinafter referred to as “level 3”) in FIG. 2C. Each voice guidance is shown.

  Level 1 is a voice guidance level when the accumulated usage time of the “NAVI” mode by the user is less than 7 hours, for example. As shown in FIG. Played. This level 1 voice guidance is unfamiliar with the user and is strong, so he is embarrassed and hiding his embarrassment, and has an attitude that pushes away the favored partner (user) The content is intended to be taken.

  Level 2 is a voice guidance level when the cumulative usage time is 7 hours or more and less than 50 hours, for example, and as shown in FIG. 4B, guidance that gives a somewhat familiar impression to the user is reproduced. This level 2 audio guidance is intended to be somewhat familiar to the user and somewhat softening the attitude towards the user.

  Level 3 is a voice guidance level when the cumulative usage time is 50 hours or more. As shown in FIG. 4C, a voice guidance that gives an impression to the user is reproduced. This level 3 voice guidance is sufficiently friendly to the user, and is intended to have a consistently relaxed attitude.

  Thus, the voice guidance level changes according to the accumulated usage time of the “NAVI” mode by the user, but also changes according to the unused time. That is, when the voice guidance level is level 3 and the unused state of the “NAVI” mode continues for 3 days or more, for example, the level is changed to level 2. Further, when the voice guidance level is level 2, for example, if the “NAVI” mode is not used for 10 days or more, the voice guidance level is changed to level 1.

(Functional configuration)
FIG. 3 is a block diagram illustrating an example of a main functional configuration of the television receiver 1. As shown in FIG. 3, the television receiver 1 includes an operation unit 11, a mode switching unit 12, a tuner 13, a demodulation unit 14, a decoder 15, an image display unit 16, an audio output unit 17, a wireless communication unit 18, and a storage unit 19. , A control unit 20, a GPS 21, and a clock unit 22 that measures current time information and notifies the control unit 20.

In the voice guidance tables 195a to 195c for each voice guidance level, voice guidance to be played in response to the operation instruction is set in association with the operation content of the operation unit 11, respectively. Note that audio content data corresponding to a plurality of sounds can be stored in advance so that the user can select according to his / her preference.

The operation content is defined by a combination of the on / off switch SW1, the channel switch SW2, the volume switch SW3, and the lightness switch SW4 as a primary operation and the press operation of the up switch SW5 and the down switch SW6 as a secondary operation. Is done.
The voice guidance is voice data such as a WAV file. Note that only the guidance number is set in the voice guidance, and the actual voice data itself may be separately stored in the storage unit 19 as a voice data group.

  The level-specific voice guidance program 193 and the voice guidance information 195 can also be obtained by downloading them to an SD card from an external server device and mounting the SD card on the device main unit 2. By doing in this way, it becomes possible to reproduce | regenerate more various audio | voice guidance according to a user preference at a multistage level.

  The usage information 197 stores data related to the usage status of the “NAVI” mode by the user. FIG. 5 is a diagram illustrating a data configuration example of the usage information 197. As shown in FIG. 5, the usage information 197 includes current usage start time 197a, previous usage end time 197b, cumulative usage time 197c, continuous usage time 197d by level, voice guidance level 197e, operation information 197f, viewing time by channel 197k. , Including viewing tendency genre 197l.

  The current use start time 197a stores time information when the use of the “NAVI” mode is started this time. The previous use end time 197b stores time information when the previous use of the “NAVI” mode is ended.

  The cumulative usage time 197c stores the cumulative usage time since the “NAVI” mode was first used. The continuous use time by level 197d is data used for determining the change of the voice guidance level, and stores the cumulative use time since the previous voice guidance level was changed.

  The voice guidance level 197e stores the current voice guidance level. The voice guidance level 197e is reset to the initial value “0” when the voice guidance level 197e is changed according to the usage status of the “NAVI” mode.

  The operation information 197f includes the number of operations of the on / off switching count 197g, the channel switching count 197h, the volume switching count 197i, and the lightness switching count 197j. The number of on / off switching times 197g is the number of on / off operations for watching TV during the “NAVI” mode, and stores the number of times the on / off switch SW1 is pressed during the “NAVI” mode. The number of channel switching operations 197h is the number of channel selection operations in the “NAVI” mode, and indicates the number of times the up switch SW5 or the down switch SW6 is pressed after the channel switch SW2 and the channel switch SW2 in the “NAVI” mode. Remember. The volume switching number 197i is the number of operations for increasing / decreasing the volume during the “NAVI” mode. The number of times the up switch SW5 or the down switch SW6 is pressed after the volume switch SW3 and the volume switch SW3 during the “NAVI” mode. Remember. The lightness switching frequency 197j is the number of light and dark adjustment operations during the “NAVI” mode. The number of times the up switch SW5 or the down switch SW6 is pressed after the lightness switch SW4 and the lightness switch SW4 during the “NAVI” mode. Remember.

  The viewing time for each channel 197k stores the viewing time for each channel in the “NAVI” mode.

  The viewing tendency genre 197l stores the genre of the viewing program in which the user has a viewing tendency in the “NAVI” mode. The control unit 20 collates viewing program information 198, which will be described later, with a broadcast program table acquired by data broadcasting, for example, and totals the viewing time for each genre. Then, the control unit 20 sets the genre having the longest viewing time as the viewing tendency genre.

  The viewing program information 198 stores data relating to a program viewed on the television receiver 1. FIG. 6 is a diagram illustrating a data configuration example of the viewing program information 198. As shown in FIG. 6, the viewing program information 198 is associated with the viewed channel, its viewing time and viewing time are set, and a new record is generated each time the channel is switched by the channel switch SW2. To be added. In the viewing program information 198, the position information of the television receiver 1 input from the GPS 21 at the time of viewing may be stored in association with each other.

  The current position information 199 updates and stores position information of the television receiver 1 that is input from the GPS 21 as needed.

The control unit 20 is realized by hardware such as a CPU. The control unit 20 performs instructions, data transfer, and the like to each unit constituting the television receiver 1 based on an operation signal input from the operation unit 11, a program and data stored in the storage unit 19, and the like. Overall operation of the receiver 1 is controlled. For example, when an operation signal is input from the operation unit 11, the control unit 20 reads a predetermined program from the storage unit 19 and controls the television receiver 1 according to the operation signal according to the read program. For example, the control unit 20 controls the tuner 13 to switch the broadcast channel, controls the audio output unit 17 to switch to a desired audio, and executes a process of increasing / decreasing the volume. In addition, the control unit 20 executes the guidance level update process according to the guidance level update program 191 and changes the voice guidance level 197e according to the usage status of the “NAVI” mode. In addition, the control unit 20 executes level-specific voice guidance processing according to the level-specific voice guidance program 193, and when an operation signal is input from the operation unit 11 during the “NAVI” mode, the voice corresponding to the voice guidance level 197e. With reference to the guidance information 195, voice guidance corresponding to the input operation signal is read out and reproduced in a preset voice such as a specific voice actor.
In addition, an external storage device such as an SD card storing audio content data to be uttered by a user's desired audio is inserted, or an external server device is accessed to cope with predetermined audio. When the audio content data is downloaded, the control unit 20 reproduces the audio guidance with the user's desired audio. In this case, the sound may be automatically converted when the storage medium is inserted, or one of the switches may function as a sound selection switch so that the user can select it by operating the switch. good.

  The GPS (Global Positioning Systems) 21 includes a GPS antenna 21a that receives radio waves from GPS satellites. The GPS 21 executes position detection processing of the television receiver 1 at predetermined time intervals under the control of the control unit 20, and extracts and controls the position information of the television receiver 1 from the radio wave received by the GPS antenna 21a. To the unit 20.

(Process flow)
First, the flow of the guidance level update process will be described. FIG. 7 is a flowchart illustrating a processing procedure of the control unit 20 according to the guidance level update processing. Note that the processing described here is realized by the control unit 20 reading and executing the guidance level update program 191.

  In this guidance level update processing, the control unit 20 uses the current time counted by the clock unit 22 when a mode determination signal for switching to the “NAVI” mode is input from the mode switching unit 12 (step S101: Yes). The current use start time 197a of the information 197 is set and updated (step S103). Subsequently, the control unit 20 calculates the unused time in the “NAVI” mode from the current time and the previous use end time 197b (step S105), and the level decreases based on the calculated unused time and the voice guidance level 197e. A determination is made (step S107). That is, when the unused time is 3 days or more and the voice guidance level 197e is “level 3”, the control unit 20 changes the level to “level 2” (step S109). At this time, the level-specific continuous use time 197d is reset to "0". Further, when the unused time is 10 days or more and the voice guidance level 197e is “level 2”, the control unit 20 changes the level to “level 1” (step S111). At this time, the level-specific continuous use time 197d is reset to "0".

  Then, the control unit 20 starts counting up the cumulative use time 197c and the continuous use time by level 197d (step S113), and monitors the continuous use time by level 197d during the “NAVI” mode to make a level increase determination. This is performed (step S115). That is, when the voice guidance level 197e is “level 1” and the continuous use time by level 197d is 7 hours or more, the control unit 20 changes the level to “level 2” (step S117). Further, when the voice guidance level 197e is “level 2” and the continuous use time by level 197d is 50 hours or more, the control unit 20 changes the voice guidance level 197e to “level 3” (step 3) S119).

  Then, the control unit 20 determines to end the “NAVI” mode when a mode determination signal for switching to a mode other than the “NAVI” mode is input from the mode switching unit 12 (step S121: Yes), and ends the previous use. The current time is set and updated at time 197b (step S123). Then, the control unit 20 stops counting up the accumulated usage time 197c and the level-specific continuous usage time 197d (step S125), and ends this processing.

  Next, the flow of level-specific voice guidance processing will be described. FIG. 8 is a flowchart showing a processing procedure of the control unit 20 related to the level-specific voice guidance processing. The process described here is a process that is started when a mode determination signal for switching to the “NAVI” mode is input from the mode switching unit 12, and the control unit 20 reads and executes the level-specific voice guidance program 193. It is realized by doing.

  In this level-specific voice guidance process, when an operation signal is input from the operation unit 11 (step S201: YES), the control unit 20 branches the process according to the type of the pressed switch (step S203). . That is, when the on / off switch SW1, the channel switch SW2, the volume switch SW3, or the brightness switch SW4 is pressed, the content of the primary operation is determined from the type of the switch (step S205). The content of the determined primary operation is temporarily stored in the storage unit 19. Subsequently, the control unit 20 determines the voice guidance level 197e of the usage information 197 (Step S207). Then, the control unit 20 refers to the voice guidance information 195 and reads out and reproduces the voice guidance corresponding to the primary operation determined in step S205 from the voice guidance table for the voice guidance level determined in step S207 (step S207). S209). Note that the control unit 20 controls the television receiver 1 according to the input operation signal, separately from the voice guidance reproduction process in step S209. Further, the control unit 20 counts up the number of operations corresponding to the operation information 197f according to the content of the primary operation determined in step S205, and updates the usage information 197 (step S211).

  If the control unit 20 determines that the up switch SW5 or the down switch SW6 has been pressed, the control unit 20 determines the content of the secondary operation from the type of the switch (step S213) and is stored in the storage unit 19. The content of the previous primary operation is read and specified (step S215). Subsequently, the control unit 20 determines the voice guidance level 197e of the usage information 197 (Step S217). Then, the control unit 20 refers to the voice guidance information 195, and from the voice guidance table for the voice guidance level determined in step S217, the content of the secondary operation determined to have been performed in step S213 and the 1 specified in step S215. The voice guidance corresponding to the combination of the contents of the next operation is read and reproduced (step S219).

Next, a second embodiment will be described. The same code | symbol is attached | subjected about the structure similar to 1st Embodiment. In addition, in 2nd Embodiment, although the case where a television receiver transmits / receives data between one broadcasting station is demonstrated, in fact, transmission / reception of data is possible between several broadcasting stations, The television receiver selects a broadcasting station that transmits and receives data according to the channel being viewed.

  FIG. 9 is a schematic diagram illustrating a system configuration example of a digital television broadcast system 30 according to the second embodiment. As shown in FIG. 9, the digital television broadcasting system 30 includes a television receiver 1b, a broadcasting station 31 including a television broadcasting system 33 and a data broadcasting system 35, and a weather information distribution server 39, and the television receiver 1b. Are connected to the data broadcasting system 35 and the weather information distribution server 39 of the broadcasting station 31 via the network N. Here, the network N is the Internet, a line for connecting to the Internet, an ISP server, or the like.

  The television receiver 1b has substantially the same configuration as the television receiver 1 described in the first embodiment. The television receiver 1b receives a terrestrial digital broadcast transmitted from the television broadcast system 33 of the broadcast station 31 and displays a broadcast program. Output. Further, the television receiver 1b updates and stores usage information including usage time and operation information of the television receiver 1b by the user, viewing information by channel, viewing tendency genre, etc., and radio waves from GPS satellites as needed by the GPS function. Is received and position information is acquired, and updated and stored as current position information. In the second embodiment, the television receiver 1b performs processing such as connection to a mobile phone line or a PHS line by using a wireless communication function and connection to the Internet using this connection. The position information is transmitted to the data broadcasting system 35 of the broadcasting station 31. The transmission timing may be a predetermined time interval, or may be a predetermined timing such as when the television receiver 1b is turned on or off, and can be set as appropriate.

  A television broadcast system 33 provided on the broadcast station 31 side transmits a broadcast wave of terrestrial digital broadcast via a radio tower 37. This broadcast wave is an image and audio signal of a broadcast program.

  On the other hand, the data broadcast system 35 includes a data broadcast content DB 35a. The data broadcast content DB 35a stores various BML contents combining still image data, text data, audio data, and the like, such as a TV program guide and news. The data broadcasting system 35 sends these BML contents in real time by broadcast waves and distributes them to the television receiver 1b to provide a data broadcasting service.

  This data broadcast content DB 35a includes genre-specific BML contents classified by genre such as movies, dramas, music, animation, and sports. Specifically, BML contents such as public information of movies for movies, BML contents such as notice information and rebroadcast guidance for drama, BML contents such as new music information for music, and so on as genre-specific BML contents. Stored. This genre-specific BML content is BML content that enables selective display of information belonging to the viewing tendency genre of the user of the television receiver 1b when reproduced on the television receiver 1b side. In the television receiver 1b that receives the genre-specific BML content, the BML browser extracts information belonging to the viewing tendency genre of the user of the television receiver 1b from the received BML content of the data broadcast, and displays it on the data broadcast screen. To display. Thereby, the information of the genre which has a viewing tendency can be provided with respect to a user.

  Further, the data broadcasting system 35 includes an additional content DB 35b, and manages the additional content individually distributed to the user of the television receiver 1b based on the usage information received from the television receiver 1b via the network N. Yes. For example, the additional content DB 35b stores character data to be displayed on the television broadcast screen or the data broadcast screen as additional content in association with the channel switching operation frequency level. The data broadcasting system 35 acquires the channel switching frequency from the operation information included in the usage information received from the television receiver 1b, and determines the operation frequency level. Then, the additional content corresponding to the operation frequency level is read from the additional content DB 35b and distributed to the television receiver 1b via the network N. For example, a user with a high frequency of channel switching operations and a large amount of so-called zapping acts is considered an unsatisfactory viewer for the current broadcast program or data broadcast content. If comprised in this way, a television broadcast and a data broadcast can be reproduced | regenerated as a content by which a character is displayed on a screen for the user with much zapping action. Note that the narration audio additional content may be distributed, or the additional content capable of applying an effect such that the broadcast image itself is displayed in a monochrome or sepia color may be distributed. Further, for example, it is possible to distribute additional content of an advertisement that is played back during a waiting time such as when switching channels.

  Furthermore, the data broadcasting system 35 includes a usage information DB 35c, and the usage information received from the television receiver 1b corresponds to the user ID, user name, etc. of the user who carries the television receiver 1b and uses the data broadcasting service.

Specifically, by summing up the viewing time for each channel, it is possible to analyze the viewing tendency for each user, the viewing tendency of the entire viewer that summarizes these viewing trends, and the like. If the television receiver 1b is configured to transmit the data related to the viewed program to the data broadcasting system 35 together with the position information acquired using the GPS function at the time of viewing, a more detailed viewing tendency can be analyzed. Can do.

  According to this, since the provider of the data broadcasting service can know the viewing tendency of the user, it is possible to provide the content according to the viewing tendency. For example, BML contents featuring CD information and music data are provided by data broadcasting when music programs as a whole are viewed by users as a whole, and sports news and sports player interviews are provided when sports programs as a whole are viewed by users as a whole. The featured BML content can be provided by data broadcasting. Thus, usage information can be used as marketing information, and BML content with high demand can be provided to the user based on the analysis result.

  In addition, the data broadcasting system 35 notifies the weather information distribution server 39 of the current position information received from the television receiver 1b via the network N, and acquires the weather information of the surrounding area. And the acquired weather information is delivered to the said television receiver 1b.

  As described above, according to the second embodiment, it is possible to provide the television receiver 1b with content corresponding to the usage information of the television receiver 1b. For this reason, it is possible to view not only televisions that are viewed passively but also communication-type televisions that reflect user actions.
