Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile terminal, and more particularly to a mobile terminal for simultaneously reproducing a plurality of contents including at least one of video data, audio data, and character data, an overlay output method, and the same. Regarding the program.

[0002]

2. Description of the Related Art In recent years, the use of the Internet by movable mobile terminals represented by mobile phones has increased.
On the other hand, data broadcasting services are becoming popular due to the digitization of program broadcasting. So, in the mobile environment,
There is a demand for a mobile terminal that can use both the program broadcasting service and the Internet.

By the way, in such a terminal that receives contents from a plurality of information sources, a plurality of types of reproduction data, that is, for example, TV video (moving image data), data broadcast (character data), and audio (content) are reproduced at the same time. Voice data), e-mail (text data, still image data, video data, voice data), homepage (text data, still image data, video data, voice data) may be played back, and more than one content can be played simultaneously. There are also cases where it is played back. However, the portable terminal is downsized in order to emphasize its portability, and the display screen for displaying the content is small. For this reason, it is not practical to display a plurality of contents on a display screen of a mobile terminal using a plurality of windows like a stationary TV. In addition, when a plurality of contents are displayed using a plurality of windows, a complicated display switching operation is required to refer to a large number of contents. However,
It can be said that it is very difficult to switch between multiple displays while moving.

As a method of referring to a plurality of contents without complicated display switching, there is an overlay display in which a plurality of contents (reproduction data) are displayed on a single screen. For example, by overlaying character data on a TV broadcast (video data), both pieces of information can be referenced at the same time. Conventionally, the OSD (On
A screen display method is known.

However, since there is a problem in that it is difficult to see just by overlaying the character data on the video data, a proposal has been made regarding the output distribution of each reproduction data used for overlay display in the OSD.

On the other hand, in the technique described in Japanese Patent Application Laid-Open No. 2001-60080, when the user adjusts the brightness and contrast of the display device, the state of the brightness and contrast, the ambient temperature and brightness are stored, and thereafter, The brightness and contrast can be automatically adjusted according to the usage conditions (temperature and brightness). As a result, even if the usage environment changes, it is possible to realize a display state that is easy for the user to see, that is, a brightness and contrast that are easy to see. In addition to the above temperature and brightness, the ID (type information) individually given to the display unit (liquid crystal) is determined, and when the display unit is replaced for repair or the like, based on the type information of the display unit. It is also described that the display state is changed by using.

[0007]

However, although the conventional overlay display has been devised to make the display itself easy to see, the distribution of each output parameter relating to the output of the reproduction data is fixed, so that it can be adjusted according to the user's preference. Therefore, there is a problem that each user cannot flexibly change the overlay display distribution.

For example, which reproduction data is mainly viewed in the overlay output information changes depending on the user's intention or the type of information. Specifically, it is assumed that an electronic mail, a TV image, and a sound corresponding to the TV image are overlay-output. When the user mainly wants to refer to the electronic mail, if the TV image stands out more than necessary, it is easily expected that the user will find the TV image unpleasant and also the TV sound unpleasant. in this case,
The user may want to display the TV image in a thin range in a distinguishable range, and may want to reduce the TV sound or delete the TV sound.

However, when the user wants to refer to the TV image at the next moment, the electronic mail displayed in the overlay is annoying, or the TV sound is too small to be heard.

As described above, which information (content) is mainly viewed and how much attention is distributed are
Since the user's usage environment and the like change from time to time, if the setting of the overlay output distribution between each reproduction data or each content is fixed, the user may have a problem when reproducing information.

On the other hand, the above-mentioned Japanese Patent Laid-Open No. 2001-6008.
0 describes a technology that automatically changes the brightness and contrast according to the usage environment. However, this technology does not change the setting of overlay output distribution between playback data or contents. Absent. Therefore, the user cannot freely set the overlay output distribution of the reproduction data (content) that is the main target of the user's viewing and the reproduction data (content) that is not the main target.

The present invention has been proposed based on the above conventional circumstances, and each user can flexibly and easily change the distribution of the overlay output of the reproduction data in accordance with the taste of the user. An object of the present invention is to provide a mobile terminal that automatically controls overlay output distribution according to the surrounding environment, an overlay output method, and a program thereof.

In the present invention, when a plurality of audio data are reproduced at the same time, the overlay output is defined together with the overlay display.

[0014]

The present invention has the following means in order to achieve the above object. That is, the present invention is premised on a mobile terminal that simultaneously reproduces a plurality of contents configured to include at least one of reproduced image data, audio data, and character data. Here, the setting means sets an output parameter, which is a parameter relating to the output of the reproduction data, for each reproduction data, and the data output control means processes each reproduction data based on the output parameter set by the setting means. Output.

Therefore, the user can arbitrarily set the overlay output distribution of the reproduction data (video data, audio data, character data) according to his or her preference.

Further, when the setting means changes the output parameter relating to the predetermined reproduction data, the output parameter relating to the reproduction data corresponding to the predetermined reproduction data may be changed.

Here, for example, when the output of one reproduction data is increased (changed) while the output of the other reproduction data is decreased (changed), it is assumed that two kinds of contents are reproduced. As the output of the content desired to be viewed increases, the output of other content (mainly content that does not need to be viewed) can be automatically lowered.

When the output of one reproduction data is increased (changed) while the output of the other reproduction data is also increased (changed), for example, when the output of video data of one content is increased. It is possible to increase the output of audio data which is reproduction data of the same content. As described above, it is possible to provide an efficient operation for changing the overlay output distribution.

Further, when the reproduction data constitutes pull-type content, the setting means may change the output parameter so as to reduce the output of the reproduction data constituting the content during acquisition of the content.

With this configuration, since it is possible to direct the user's consciousness to a content different from the content being acquired, it is possible to reduce the user's discomfort to the waiting time required to acquire the pull-type content. It will be possible.

Further, if the output parameter is changed so as to increase the output of the reproduction data that composes the pull-type content according to the reception status of the pull-type content, the uncomfortable feeling of waiting time is only reduced. Instead, the output can be used to notify the user of the reception status of the content.

Further, a reservation means for storing the reproduction time of the content and a timer means for monitoring the reproduction time stored in the reservation means are provided, and the setting means receives the notification of the reproduction time from the timer means and responds to the predetermined value. There is a configuration in which the output parameter is changed so as to increase the output of the reproduction data that constitutes the content of.

Even with this configuration, it is possible to change the output parameter according to a predetermined time, and it is possible to provide an efficient operation for changing the overlay output distribution.

Further, there is a configuration in which a parameter storage means for storing the set output parameter is provided, and the output parameter is read from and written to the parameter storage means as required.

In the above configuration, the output parameter suitable for each situation is stored in the parameter storage means in advance, and the user can call the output parameter, so that the user can easily and appropriately select the reproduced data. Output parameters can be set.

In addition, the output parameter relating to the video data can change the brightness of the specific video data in the configuration including the brightness and / or the color, so that the video data and the characters in accordance with the user's viewing priority order can be changed. Information can be displayed as an overlay.

Furthermore, the setting means has a configuration for setting output parameters based on information obtained from the broadcast data decoder, and a configuration for setting output parameters based on information obtained from the network data decoder.

In the above configuration, not only the display of the user can be controlled based on the intention of the broadcast transmitting side, but also a large number of specified output parameters can be distributed at once by broadcasting.

Furthermore, the setting means has a configuration for setting the output parameter based on the information stored in the external storage medium.

In the above configuration, the user can send / receive the output parameter by storing his / her favorite output parameter in the external storage medium and passing it to another person.

Still further, the portable terminal is provided with a scanner, and the setting means sets the output parameter based on the information read from the print medium via the scanner.

With the above arrangement, it is possible to easily input the output parameters printed on the printed matter, for example.

Furthermore, there is a configuration in which the portable terminal is equipped with GPS, and the setting means sets the output parameter based on the position information obtained from the GPS.

In the above configuration, for example, the position data received from the GPS is compared with the position data of the predetermined area, and when it is determined that the user is in the position data of the predetermined area, the area-specific information is displayed. It is possible to change the “brightness” parameter and the “color” parameter and display the information peculiar to the area in a conspicuous manner.

Furthermore, the portable terminal is provided with an optical sensor,
The setting means has a configuration for setting the output parameter based on the brightness information obtained from the optical sensor.

In the above configuration, the "brightness" parameter and the "color" parameter are changed based on the light and shade data obtained from the optical sensor, so that it is possible to automatically perform overlay display that is easily recognized by the user. .

Furthermore, the setting means has a configuration for setting the output parameter based on speed information which is the moving speed of the portable terminal.

In the above configuration, for example, the volume of the voice data is kept constant, and the display of the video data and the character data on the display unit is faded out as the moving speed becomes faster, so that dangerous side-looking driving can be prevented. Become.

The present invention can be provided as a program that is individually distributed via a telecommunication line or the like. In this case, a central processing unit (CPU) not shown
The control unit including
The control operation is realized in cooperation with each circuit other than U. However, each unit realized by using the program and the CPU may be configured by using dedicated hardware. Further, the program may be distributed in a state of being recorded in a computer-readable recording medium such as a CD-ROM.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the accompanying drawings to provide an understanding of the present invention.
It should be noted that the following embodiment is an example in which the present invention is embodied, and does not limit the technical scope of the present invention.

Here, the contents in the present invention are:
This information is reproduction data, that is, information including at least one of video data, audio data, and character data, and corresponds to TV video, data broadcasting, audio, electronic mail, homepage, and the like. Video data includes still image data and moving image data.

(Embodiment 1) A portable terminal according to the present invention will be described below with reference to FIGS. 1, 2, 3, 4, and 5. Note that FIG. 1 is a schematic functional block diagram of the mobile terminal according to the present embodiment.

First, the configuration of the mobile terminal according to the first embodiment will be described. Mobile terminal 500 in FIG.
Shows an example of an overview of the mobile terminal 100 of FIG. The mobile terminal 500 includes an antenna 501 for receiving digital broadcasting (television broadcasting, radio broadcasting) and wireless network access, and a display (display unit) 5 for displaying digital broadcasting and network data as necessary.
02, a cross key 503 for receiving up / down / left / right instructions from the user, an information acquisition key 504, and a terminal (not shown) for outputting a voice. In the example of FIG. 5, the terminal for outputting the sound is connected to the headphones 505.

The portable terminal 100 is provided with, for example, a digital broadcasting tuner 101 and a transmitting / receiving means 106 for transmitting / receiving data via a network such as the Internet,
Digital broadcasting, homepages on the Internet, electronic mails, and the like can be transmitted and received via the antenna 501.
However, a plurality of inputs are not necessarily required, and for example, only the transmitting / receiving unit 106 is provided, and the transmitting / receiving unit 1 is provided.
06 may receive both digital broadcasting and electronic mail via a network.

Hereinafter, referring to FIG. 1, FIG. 2, FIG. 3, and FIG.
A process of overlay-displaying video data and character data will be specifically described.

Here, the video data 510 shown in FIG.
A video showing a train, and the broadcast data 520 is a URL (Uniform) indicating the position where the video data 510 is stored.
Character data that includes a character string of mResource Locator). In this case, the video data and the character data form the same content. However, when the character data is received independently (text broadcasting), the video data and the character data can be defined as different contents.
The train moving image is updated with time, that is, the example of FIG. 5 merely shows an example of data and a display example at a certain time.

First, the content including video, audio, characters, etc. received as multiplexed data by the digital broadcast tuner 101 via the antenna 501 is TS (Tr
The reproduced data (video data, audio data, character data) is separated by the ansport stream decoder 102 (FIG. 2: S201).

Next, of the separated reproduction data, video data is input to the video decoder 104, audio data is input to the audio decoder 103, and character data is input to the broadcast data decoder 105, and the decoders 103 to 105 respectively. The data output control means 108 is converted into a reproducible format.
(FIG. 2: S202).

Next, as shown in FIG. 3, among the respective reproduction data transmitted to the data output control means 108, the reproduction data from the audio decoder is the audio memory 301 and the reproduction data from the video decoder 104 is the video memory. At 302,
Reproduced data from the broadcast decoder 105 is received by the broadcast data memory 303.

The reproduced data received by the transmitting / receiving means 106 is converted into a reproducible format by the network decoder 107 and transmitted to the data output control means 108. Here, with respect to the reproduction data received by the transmitting / receiving means 106, reproduction data of various formats such as audio data, video data, character data, etc. can be considered, but here it is treated as character data.

When the reproduction data (audio data, video data, character data, network data) input to the portable terminal 100 is transmitted to the data output control means 108, the audio memory 301 and the video memory 302 shown in FIG. 3 respectively. , The broadcast data memory 303 and the network data memory 304 are overlaid and temporarily stored in the drawing memory 300 (FIG. 2: S203N).
o → S205). Incidentally, the above-mentioned reproduction data is the drawing memory 3
In the previous stage stored in 00, the functions F1 (X), F2 (X), F3 (X), F having output parameters as variable groups are stored.
4 (X) gives a predetermined effect, which will be described in detail later.

The reproduction data (for display) stored in the drawing memory 300 is displayed on the display unit 112 (display 50).
It is displayed in 2). However, although the voice data is directly output from the voice memory 301 without being overlaid, for example, when the network data includes voice data,
Audio data is also overlaid and output.

Display 506 shows an example in which the video data 510 and the broadcast data 520 are overlaid and displayed on the display unit 112.

The above is a general processing method for overlay output, but in the present invention, it is possible to set output parameters independently for the reproduction data. The details of the process of setting the output parameters will be described below.

Here, the above-mentioned output parameter indicates a variable group that applies a predetermined effect to the reproduction data when reproducing the reproduction data. In the first embodiment, the output parameters of the audio data correspond to "volume" and "sound quality", and the output parameters of the video data and character data correspond to "luminance" and "color". The display unit 11 remains as input without adding a predetermined effect to the reproduction data.
In the case of displaying in 2, the output parameter of each reproduction data is set to "1.0" as shown by the initial value 401 in FIG.

When the user of the portable terminal 100 looks at the display section 112 by paying attention to digital broadcasting, for example, the cross key 503 is used to display the brightness of the display related to the digital broadcasting (broadcast data 400). Perform the raising operation. Specifically, for example, the operation is performed by the cross key 50.
For example, the operation of pressing the "up" of 3. When the "up" of the cross key 503 is pressed, the setting means 109 raises the brightness parameter 403 of the video data by "0.1".

Furthermore, the brightness parameter 404 of the character data and the volume parameter 405 of the audio data having the same content as the video data are set to the brightness parameter 40.
You may raise in conjunction with 3. Furthermore, the broadcast data 40
The brightness parameter 402 of reproduction data other than 0 (here, network data) may be lowered by "0.1" in conjunction with the operation of increasing the brightness parameter 403 of video data.

The respective output parameters changed by the setting means 109 as described above are the data output control means 10
8 is sent.

Next, the details of the processing of the data output control means which has received the respective reproduction data and the respective output parameters will be described.

The data output control means 108 outputs the output parameters α, β, and video data, audio data, character data, and network data from the setting means 109, respectively.
When γ and δ are received, for example, predetermined functions F1 (volume, sound quality), F2 (luminance, color), F3 (luminance, color), F4
A predetermined effect is applied to each reproduction data by using (luminance, color) (FIG. 2: S203 Yes → S204). That is, for example, the effect derived from F1 (α) is applied to the audio data once stored in the audio memory 301, and F2 is applied to the video data stored in the video memory 302.
The effect derived from (β) is applied.

Here, to give a concrete example, the above F2
(Β) is a function that applies a predetermined effect to the video data based on the brightness and the color, and the output parameter β is (1.9
, 1.0), F2 (β) is the video memory 302
When the video data stored in is reproduced as it is (β = (1.0, 1.0)), it is brighter than the brightness. An image when the brightness of the video data 510 is increased and the brightness of the broadcast data 520 is decreased is shown in an image 530 of FIG. Since the video data (train) stands out and the broadcast data (URL) becomes inconspicuous, the user can easily see the video data. If the color parameter includes, for example, “0.0”, the video data is changed to, for example, black and white or sepia tone based on the numerical value.

Further, the output parameter α is added to the F1 (X).
When F1 (α) in which = (1.9, 1.0) is substituted is applied to the reproduction data stored in the audio memory 301, the audio data is reproduced as it is (α = (1.0, 1.0))
Will be louder than the volume. Further, if the sound quality parameter includes any numerical value, the sound quality of the audio data is changed based on the numerical value.

Similarly to the above, the effect given by F3 (γ) is applied to the character data stored in the broadcast data memory 303, and the effect given by F4 (δ) is stored in the network data memory 304, for example. Applied to network data.

The above-mentioned audio data which has been subjected to a predetermined effect by the data output control means 108 is output from the speaker 111 (headphones 505). In addition, data relating to a display on which a predetermined effect is applied, that is, here, image data,
Character data and network data are temporarily displayed in the drawing memory 3
After being combined (that is, overlaid) with 00, the display unit 1
12 is output (FIG. 2: S205 → S206).

As described above, the output parameters α to δ, which are the input values for determining the values of the functions F1 to F4, are the cross keys 50.
It can be set by instructing the vertical direction of 3. Therefore, the user can operate the cross key 503 up and down to arbitrarily set the overlay distribution of the user's favorite video data, audio data, character data, and network data. Moreover, since the brightness of specific video data can be changed, the user's preference,
That is, overlay display of video data and text information according to the viewing priority can be performed.

Note that, for example, the output parameter for the video data stored in the video data memory 302 is β = [βi;
i = 1,2, ..., n], and output parameters for the broadcast data stored in the broadcast data memory 303 are γ = [γi; i = 1,2,
.., n], and the user may directly change β or γ (where i is the number of parameters).

In this case, for example, βi + γi = 1 and 0 ≦ βi ≦ 1, 0 ≦ γi ≦ 1, and if βi → 1, then γi → 0, that is, the video data 510 is made conspicuous. By doing so, the overlay output may be changed so that the broadcast data 520 is automatically inconspicuous.

Conversely, if βi → 0, then γi → 1 and
By making the broadcast data 520 conspicuous, the overlay output is automatically changed so that the video data 510 becomes inconspicuous.

In the portable terminal according to the present invention, any method may be used, for example, a modulation method of broadcast video, audio, character data, a multiplexing method, an error correction method, and the like. The same applies to the format of data transmitted / received via the transmitting / receiving means 106.

Furthermore, the output parameters α, β,
γ and δ are voice output effects, which is the object of the present invention,
And output parameters that constitute a function for obtaining the image output effect and are associated with each other, but may be set independently.

The output parameters α, β, γ, δ are not limited to the above two output parameters, but may be composed of a plurality of parameters other than the above.

It is needless to say that the numerical values of the above output parameters are examples and any value may be taken.

Furthermore, in the first embodiment, the user operates the portable terminal 500 using the cross key 503, but the operation using the cross key is not directly related to the present invention, that is, the operation is not performed. This is a simplified representation of the description. Therefore, the details of the procedure for selecting each output parameter are also omitted. As a method of selecting each output parameter, for example, a procedure of displaying a menu once, selecting the output parameter by the user selecting the menu, and then changing the output parameter using the cross key can be considered. However, it is not particularly limited. Also in the following embodiments, the operation using the cross key will be briefly described.

(Embodiment 2) In Embodiment 2, in addition to Embodiment 1 described above, an application example will be used for understanding the invention.

First, an embodiment will be described in which, in addition to the output parameters "luminance" and "color" relating to the above-mentioned video / character, an "update frequency" is further provided. The “update frequency” parameter can be applied when the video data is moving image data.

For example, the output parameter β = (luminance,
Color, update frequency). The "update frequency" is a parameter that determines the playback speed of the moving image data when it is received, and its default setting value is "1.0".

Here, as shown in the first embodiment, the user can arbitrarily change the "update frequency" parameter by pressing the cross key 503 in the vertical direction. When "0.0" is set in the "update frequency" parameter, the function F2 (β) is caused to stop the moving image of the train (video data 510), and "0.5" is set in the "update frequency" parameter. If the function F2 (β)
Operates so as to reproduce the moving image of the train (image data 510) at half the normal speed.

By using the above-mentioned "update frequency" parameter, the screen of the changing video data is stopped or set to the frame-by-frame display so that the data other than the moving image data, that is, the character data such as the broadcast data and the network data is read. It is possible to make it easier. Furthermore, it is possible to make the video data easier to see by stopping the broadcast data that changes similarly to the above.

In this case, pressing the "right" of the cross key 503 stops the video data, or the cross key 503 is pressed.
The broadcast data may be stopped by pressing "left" of. In addition, the stopped video data is displayed again with the cross key 5
The stop can be released by pressing the "right" of 03.
Similarly, the stopped broadcast data can be released by pressing the right key of the cross key 503 again.

In the example of FIG. 5, the train image data 510 and the broadcast data 520 of URL characters “www.train.com” are simultaneously broadcast, and the display 502 is displayed.
The overlay is output in. The video data 510 of the train and the broadcast data 520 of URL characters are changing with time, and the user operates the cross key 503 in the vertical direction so that the information of both the video data 510 and the broadcast data 520 is distributed to the user's attention. It is possible to simultaneously refer to the combined overlay output allocation. The user can also freeze the video data 510 and the broadcast data 520 by operating the cross key 503 in the left-right direction.

At this time, the output of the audio data can be controlled by increasing or decreasing the volume according to the display of the video data 510 or the broadcast data 520, and the output of the video data 510 or the broadcast data 520 can be controlled. It can also be controlled independently of the display.

To match the display of the video data 510,
Function F2 for effecting the video memory 302 described above
(Β) and a function F1 for effecting the voice memory 301
By making (α) proportional, the video data 510
Is displayed more prominently, the video data 51
The TV sound associated with 0 can also be increased, and the sound associated with the video data can be reduced while the broadcast data 520 is displayed conspicuously.

(Third Embodiment) In the second embodiment, video data 510 broadcast from a broadcasting station and broadcast data 520 simultaneously broadcast in association with the video data 510, that is, reproduction constituting the same content. An example of overlay output between data has been shown, but in the third embodiment, a case will be described in which the data output as overlay output to the video data 510 is network data acquired via a network.

In the data broadcasting service for digital broadcasting, it is possible to broadcast the URL data related to the program as shown by the broadcasting data 520 in FIG. Since the mobile terminal 100 according to the present invention includes the transmission / reception means 106 shown in FIG. 1, it acquires the URL data to be broadcast, and the WWW (World Wide Wed) indicated by the URL.
b) It is possible to display the home page above.

In the example of FIG. 5, the broadcast data 520 is "ww
w. train. com ", but here,
As the broadcast data 520, URL data indicating the content of the character string is simultaneously broadcast. The user presses the information acquisition key 504 of the mobile terminal 500 to
www. train. The homepage data 601 indicated by "com" is acquired via the transmitting / receiving means 106 and stored in the network data memory 304 via the network data decoder 107. The contents of the network data memory 304 and the contents of the video data memory 302 are as follows. After being combined in the drawing memory 300, the mobile terminal 50
0 is output as an overlay on the display 502.

Here, the user can arbitrarily change the overlay output distribution by the same means as the overlay output of the video data 510 and the broadcast data 520 described above. Also in this case, the output of the audio data (“volume” parameter) can be increased or decreased according to the display of the video data 510 or the homepage data 601. Although the homepage data 601 is character data in the example of FIG. 5, it may be video data, that is, still image data or moving image data.

In the above example, an example of the overlay output of the video data 510 broadcast from the broadcasting station and the homepage data 601 which is the network data acquired via the network is shown.
It is also possible to use 1 as the electronic mail data 602.

Generally, when referring to a home page or an electronic mail, the user needs to pay considerable attention to them. Therefore, in this case, overlay output may not be performed and only the homepage or email may be referred to. However, when browsing the homepage or email for a while during TV viewing, it is necessary to have an opportunity to return to TV viewing. Become. Therefore, if the audio data is independently output without displaying the video data, the user can return to the viewing of the video data (television) by relying on the audio.

In the above example, as the combination of the data to be overlay-outputted, the video data 510 and the broadcast data 520, the video data 510 and the homepage data 60 are combined.
1, the video data 510 and the e-mail data 602, but the broadcast data 520 and the homepage data 60
1, the combination of the broadcast data 50 and the electronic mail data 602, the homepage data 601 and the electronic mail data 602, and the combination with the audio data are also possible.

Further, although the program broadcasting is assumed to be digital broadcasting, it is also possible to use radio broadcasting or broadcasting via the Internet.

As described above, in the portable terminal 100 according to the present invention, between the broadcast video data / audio data and the broadcast data, or the broadcast video data / audio data and the homepage data acquired from the network.
It is possible for the user to arbitrarily change the overlay output distribution between various contents such as e-mail data.

Further, the output of the audio data can be controlled to be increased or decreased according to the display (output) of the video data or the homepage data / e-mail data.
It can also be controlled independently of the display of email data.

As described above, the user can effectively receive the program broadcasting service and the Internet service by arbitrarily changing the overlay output distribution in the mobile terminal having the limited display capability.

(Fourth Embodiment) Next, an example in which the output parameter of the reproduction data is dynamically changed according to the acquisition state of the reproduction data will be described with reference to FIGS.

For example, a home page or an electronic mail that the above-mentioned terminal acquires from the Internet or the like is pull-type content. That is, the pull-type content is content that the mobile terminal voluntarily acquires from another terminal when the user gives an instruction to the mobile terminal. Also, the reproduction data that constitutes the pull-type content is set as pull-type data.

When acquiring the above-mentioned pull-type contents, T
Unlike the V image, a wait time image is generated after the user gives an instruction until all pull-type data is acquired. The longer this waiting time is, the more time the user needs to spend, and it is easy to expect that the user will feel uncomfortable.

Therefore, in the fourth embodiment, when the pull-type content is acquired, the output parameter relating to the data is changed to reduce the discomfort of the user.

First, FIG. 9 is a diagram showing a part of a schematic functional block diagram of a portable terminal according to the fourth embodiment. Specifically, the network data decoder 107 in the first embodiment is the browser 901, but the browser is an embodiment of the network data decoder.

In giving an example, consider a case where the browser 901 obtains a certain homepage through the transmitting / receiving means 106, and the user further overlays and displays the homepage and the TV broadcast (sports program). It is assumed that the user is browsing from the section 112.

Although the user mainly browses the homepage data output from the browser 901 through the display unit 112, the display brightness of the sports program, which is a content different from the homepage, is lowered to display the homepage. It is assumed that the overlay is output to. in this case,
The above-mentioned users mainly browse the homepage, but at the time when there is a fine play etc. in a sports program,
On the contrary, as described above, there is a usage method in which the user watches the sports program by raising the display luminance of the sports program and lowering the display luminance of the home page.

Here, first, for example, the link information etc. written on the home page currently being browsed by the user is displayed on the display unit 1, for example.
It is assumed that the user selects (tap) via 12. In this case, the selection is transmitted to the browser 901, and the browser 901 that has received the selection transmits the data corresponding to the selection, for example, the data of the home page which is the link destination, via the transmitting / receiving unit 106. Try to receive. At this time, prior to receiving, the browser 901 transmits to the data output control means 108 that the data of the home page will be received.

The data output control means 108, which has received the above-mentioned "receipt of homepage data", changes the output parameter so as to reduce the display brightness of the pull-type content input from the browser 901.

FIG. 7A is a diagram showing the relationship between the change of the output parameter by the data output control means 108 and each content (homepage and TV broadcast) displayed on the display unit 112.

That is, the time when the output control means 108 receives the above-mentioned "receive homepage data" is T
s, at time Ts, the display brightness of the home page is T
It is lower than the output of V video. Accordingly, when the browser 901 receives the reproduction data of the pull-type content, the display brightness of the TV image is higher than that of the home page, that is, the user's consciousness is from the home page to the TV
I will move to the video.

Next, at a predetermined time Te, the browser 9
When 01 has received the home page data, the data output control means 1 indicates that the home page has been received.
08. The data output control means 108 which has received the above-mentioned "reception of homepage completion" changes the output parameter so that the display brightness of the homepage is returned to the state before the time Ts at the time Te.

As a result, the user's consciousness is again TV.
You will move from the video to the home page.

As described above, while the pull-type content is being acquired, the output parameter is changed so as to reduce the output of the reproduction data corresponding to the pull-type content. It is possible to point to different content. Therefore, it is possible to reduce the user's discomfort for the waiting time required to acquire the pull-type content.

In the above description, although the display brightness of the home page is lowered but the display brightness of the TV image is not changed, for example, as shown in FIG. The output parameter may be changed so as to increase the display brightness. As a result, it becomes possible to further direct the user's consciousness to the TV image.

As an application of the above-mentioned example, the following output may be made.

That is, for example, when the user selects the display unit 112 to instruct the browser 901 to acquire pull-type content, the browser 901 receives the message “receive homepage data” at time Ts and the current time. The progress status of reception (0% at this point) is transmitted to the data output control means (FIG. 10: S1001 → S1002). The data output control means 108 reduces the output of the home page by changing the output parameter in response to the "reception of home page data" and the current progress of reception (FIG. 10: S1003).

FIG. 8 shows the relationship between the TV image and the output of the home page.

That is, the output of the home page is initially 80.
It can be seen that the value of 1 decreased to the output 802 at time Ts. The output shown in the output 802 is set to 0%, and the output shown in the output 801 is set to 10%.
0%

Next, it is assumed that the browser 901 sequentially transmits the reception status of the home page to the data output control means 108. For example, at time T1, if the reception of the homepage is completed by 25%, the fact is transmitted to the data output means 108, and the data output control means 108 changes the output parameter so as to increase the output of the homepage by 25%, and the display unit To (S1004 → S in FIG. 10)
1005).

Similarly to the above, if the reception is completed 50% at time T2, the output of the home page is 50% at time T2.
Then, when the reception is completed 75% at time T3, the output of the homepage is made 75% at time T3 (FIG. 10:
S1006 → S1009).

Finally, when the reception is 100% completed at time Te, the output of the home page is 100 at time Te.
%, That is, the output 801 (FIG. 10: S1010 → S1
011).

As described above, while the pull-type content is being acquired, the output parameter is set so as to increase the output of the reproduction data forming the pull-type content according to the reception status (acquisition status) of the pull-type content. By changing,
Not only can the discomfort of the user for the waiting time be reduced, but the output can be used to notify the user of the reception status of the content.

In the case where the pull-type content is a home page, the output is changed depending on the amount of received data. For example, in the case of electronic mail, the number of received mails relative to the total number of unreceived mails at the start of reception is output. It may be reflected.

(Fifth Embodiment) Next, FIG. 11 to FIG.
Another example in which the output parameter of the reproduction data is dynamically changed according to the situation will be described using.

First, FIG. 12 is a diagram showing a part of a schematic functional block diagram of a portable terminal according to the fifth embodiment.
Specifically, the mobile terminal 100 according to the first embodiment described above.
In addition to the above configuration, the reservation means 1201 and the timer means 12
With 02.

To give an example here, the reservation means 12
In 01, it is assumed that the start time, the reserved channel, and the end time of the TV program that the user views in advance are stored. It should be noted that the setting procedure for storing is omitted since it is not particularly related to the present invention.

As in the fourth embodiment, the user mainly browses the home page output from the browser 901 through the display unit 112, but the display brightness of the TV image which is a content different from the home page. Lower
Overlay output to the above website.

Here, first, the timer means 1202.
Makes an inquiry (polling) to the reservation means 1201.
(FIG. 13: S1301). At this time, the reservation means 1201 that has received the polling, if it is not the start time of the set TV program, notifies the timer means 120 accordingly.
2 (FIG. 13: S1302) Here, when the polling is performed at time Tp and there is a start time of the TV program set for this, the reservation unit 1201 notifies the fact and reservation. The channel is transmitted to the timer means 1202 (FIG. 13: S1303 →
S1304).

When the timer means 1202 receives the start time, it sends the start time and the reserved channel to the data output control means 108 (FIG. 13: S1305).

When the start time is received and the reserved channel is received, the data output control means 108 increases the display brightness of the TV image of the reserved channel currently displayed on the display unit 112, for example. TV concerned
Change the output parameters of the playback data that make up the video. Further, the data output control means 108 processes the reproduction data based on the changed output parameter and outputs it to the display unit 112 (FIG. 13: S1306).

FIG. 11 is a diagram showing the relationship between the change of the output parameters by the data output control means 108 and each content (homepage and TV image) displayed on the display unit 112.

That is, it can be seen that the display brightness of the TV image increases at the start time Tp. On the other hand, for example, in association with the change of the output parameter of the TV image (reproduction data), the output parameter of the home page may be changed to reduce the display brightness of the home page.
As a result, the above-mentioned user's consciousness is changed from the homepage to the TV.
I will move to the video.

Subsequently, the timer means 1202 makes an inquiry to the reservation means 1201 and the reservation means 12
01 determines the preset end time (FIG. 13: S1307).

If the end time is not reached, the timer means 1202 is notified to that effect (FIG. 13: S13).
07).

If the end time is reached, the timer means 1202 is notified of that fact, and the timer means 1202 that has received the notification notifies the data output control means 1 accordingly.
08 is notified (FIG. 13: S1309 → S1310).

The data output means 108 that has received the notification that it is the end time changes the output parameters so that, for example, the display brightness of the TV image and the display brightness of the home page become the same as the state at the time Tp. .

Also, the data output control means 108 is
The reproduction data is processed based on the changed output parameter and output to the display unit 112 (FIG. 13: S131).
1). As a result, the awareness of the user again shifts from the TV image to the home page.

As described above, by providing the timer means and the reservation means, it becomes possible to change the output parameter according to a predetermined time. This makes it possible to improve the convenience of the user.

(Sixth Embodiment) Next, a process for easily calling the output parameter set by the user in the sixth embodiment will be described.

In the sixth embodiment, the mobile terminal 10
0 further includes a parameter storage unit 110, in which various combinations of output parameters are stored in advance.

In FIG. 4, a "setting name" 407 table stores a name that allows the user to know in which case the setting is valid. “TV”, “e-mail”, “indoor”, “outdoor”, etc.

First, in the portable terminal 100, a desired setting item, for example, "TV" can be selected from the setting name 407 by a predetermined operation of the user. Specifically, by pressing a menu button (not shown), a “setting change menu” or the like is displayed on the display unit 112, and the cross key 503 is used to select a desired setting name.

When the user selects the desired setting name, the setting means 109 reads out the settings corresponding to the setting name, that is, the output parameters of the audio data, video data, character data, and network data. continue,
The setting unit 109 transmits the read output parameter to the data output control unit 108.

More specifically, for example, when the user selects "e-mail", digital broadcasting (broadcast data 4
00), the brightness of the output parameter related to the network parameter 00) is set low, and the brightness of the output parameter related to the network data is set high.
6 is read by the setting means 109.

After that, as in the case of the processing described in the first embodiment, after the output parameter applies a predetermined effect to each reproduction data, the reproduction data is overlay-outputted.

As described above, by providing the parameter storage means for storing the output parameters suitable for each situation in advance and allowing the user to call the output parameters,
The user can easily set appropriate output parameters for the reproduced data.

By allowing the user to freely change the output parameters that have been called up, the user can customize the output parameters to his or her preference and set overlay output. Furthermore, the setting unit 109 stores the customized output parameter in the parameter storage unit 110.
By enabling the storage of the output parameters, the user can set desired output parameters as appropriate.

(Embodiment 7) In each of the above embodiments, the change of the output parameter is determined by the user. However, the determination of the output parameter does not need to be limited to the input by the user, so the method of inputting other output parameters will be described below.

First, input of output parameters from the broadcast decoder 105 can be considered.

By allowing output parameters to be input from the broadcast decoder, each output parameter can be set from the standpoint of transmitting a broadcast. When the brightness of the video data is displayed with lowering and the output of the audio data is also decreasing, it is possible that the user may not notice the tsunami warning or the emergency news that tells the evacuation site when a natural disaster such as an earthquake occurs. To be In such a case, the broadcast transmitting side can change the output parameter to efficiently convey the emergency news or the like to the user. Further, not only the display for the user can be controlled based on the intention of the broadcast transmitting side, but also a large number of specified output parameters can be distributed at once by broadcasting.

Also, instead of the input from the broadcast decoder 105, the output parameter can be input from the network data decoder 107, so that the same effect can be obtained.

Furthermore, by providing a memory card interface in the portable terminal 100 and connecting a memory card (external storage medium) storing output parameters to the memory card interface, the setting means 109 stores in the memory card. The output parameter thus obtained may be read. Of course, the setting means 109 may write to the memory card.

With this configuration, the user can send / receive / distribute the output parameter by storing his / her favorite output parameter in the memory card and passing it to another person.

Furthermore, for example, the portable terminal may be equipped with a (handy) scanner, and the output parameter printed as a barcode or numerical value on, for example, a magazine or a book may be read and input to the setting means 109.

Furthermore, it is also possible to input data relating to the brightness of the environment referring to the terminal acquired from the optical sensor, and the setting means 109 to determine the output parameter based on the data relating to the brightness.

For example, when the user is indoors, the display contents can be relatively recognized even if the "brightness" parameter is lowered a little. However, when the user goes outdoors with the output parameter lowered, the display may be dark and it may be difficult to recognize the display contents, and the same applies to day and night. In such a case, by changing the "brightness" parameter or the "color" parameter based on the light / dark data obtained from the optical sensor, it becomes possible to automatically perform overlay output that is easily recognized by the user. . The setting name 407 may be selected instead of changing the output parameter based on the light / dark data.

Furthermore, GPS (Global Pos)
It is also possible to input the position data of the terminal acquired from the positioning system), change the setting of the output parameter based on the position data, or select the setting name 407.

The following can be considered as a method of using the above GPS. That is, for example, it is conceivable that position data (range) of a predetermined area and information unique to the area are transmitted by digital broadcasting. In such a case, the setting means 109 compares the position data received from, for example, GPS with the position data of the above-mentioned predetermined area, and when it is determined that the user is within the position data of the predetermined area, By changing the “luminance” parameter and “color” parameter of the peculiar information, the information peculiar to the region is displayed so as to stand out.

As described above, the mobile terminal 100 can change the overlay output based on the position data.

Furthermore, for example, in the case of an on-vehicle portable terminal,
The speed data (speed information) acquired from the speed sensor may be input to the mobile terminal 100, the setting of the output parameter may be changed based on the speed data, or the setting name 407 may be selected.

The following can be considered as a method of using the above speed sensor. That is, for example, the volume of the audio data is kept constant, and the display of the video data and the character data on the display unit is faded out as the moving speed becomes faster.

Further, the movement amount per unit time, that is, the speed may be calculated from the position information obtained from the GPS.

Although the embodiment of the present invention refers to a movable portable terminal, it can be applied not only to a mobile environment but also to a terminal used in a fixed environment.

[0158]

As described above, the user can arbitrarily set the overlay distribution of video data, audio data, broadcast data (character data) and network data according to his or her preference, and change the brightness of specific video data. Therefore, it is possible to overlay display of video data and character information in accordance with the user's preference, that is, the viewing priority.

When the output of one reproduction data is increased (changed) while the output of the other reproduction data is decreased (changed), assuming that two kinds of contents are reproduced, it is mainly seen. As the output of the desired content increases,
The output of other content (content that does not need to be seen mainly) can be automatically lowered.

Furthermore, when the output of one reproduction data is increased (changed) while the output of the other reproduction data is also increased (changed), for example, when the output of video data of one content is increased. It is possible to increase the output of audio data which is reproduction data of the same content.

This makes it possible to provide an efficient operation for changing the overlay output.

When the reproduction data constitutes pull-type content, the setting means changes the output parameter so as to reduce the output of the reproduction data constituting the content while the content is being acquired. It is possible to reduce the discomfort to the waiting time required for acquiring pull-type content.

Furthermore, by changing the output parameter so as to increase the output of the reproduction data forming the content according to the reception status of the pull-type content, the output is used to notify the user of the content reception status. It becomes possible.

Further, by storing the output parameters suitable for each situation in advance in the parameter storage means so that the user can call the output parameters, the user can easily and properly output the output parameters to the reproduced data. Can be set.

Furthermore, the setting means sets the output parameter based on the information obtained from the broadcast data decoder, or sets the output parameter based on the information obtained from the network data decoder. Not only can the display of the user be controlled based on the above, but a large amount of prescribed output parameters can be distributed at once by broadcasting.
