DETAILED DESCRIPTION OF THE INVENTION
As shown in FIG. 1, the in-vehicle information receiving and displaying apparatus according to the embodiment of the present invention receives a mobile communication or broadcast signal, and temporarily stores the signal, and receives the display restriction on the received information. A storage unit 12 that stores display restriction standards including whether or not to be added as a database, a travel detection unit 13 that detects the travel state of a vehicle, and detection that an importance code is added to the received information. The importance code detection unit 14 to perform, the dynamic display detection unit 15 to detect whether the received information includes a dynamic display, the storage unit 12, the travel detection unit 13, and the importance code detection unit 14 The display restriction unit 16 determines the contents of display restriction including the necessity of display of the received information based on the information of the information, and performs signal processing on the reception information according to the information of the travel detection part 13 and the display restriction part 16 to restrict the display restriction. Do Control unit 17, a display unit 18 for displaying the information outputted from the control unit 17 is configured character information from the voice output unit 20 for outputting a sound that is the sound conversion unit 19 and converted into a voice information.
[0013]
Next, the operation of the in-vehicle information receiving display device configured as described above will be described with reference to FIGS. FIG. 2 shows an example of the information transmission signal, and FIG. 3 is a flowchart showing the operation of the in-vehicle information receiving display device of the present invention.
[0014]
The importance code indicating the importance of the information is transmitted after being added after the header of the signal as shown in FIG. This is an example, and other schemes such as addition in the header may be used.
[0015]
First, the receiving unit 11 receives the mobile communication or broadcast signal and stores it (S1), and the travel detection unit 13 detects whether or not the vehicle is traveling (S2). If there is, the information by the received signal is not regulated and the information is output to the display unit 18 and displayed (S3). The running state of the car can be detected from, for example, the state of a parking lamp switch that is linked to a side brake (not shown). If the vehicle is traveling, the importance code detection unit 14 detects whether or not the importance code is added to the received and stored signal (S4), and if the importance code is added. The dynamic display detection unit 15 checks whether the information includes dynamic display information such as blinking information of characters and / or graphics or moving picture information (S5), and the information includes dynamic display. If not, the information is displayed on the display unit 18 without being restricted (S3).
[0016]
The presence / absence of dynamic display can be detected by detecting changes in screen information that are continuous over time. If dynamic display is included, it is confirmed whether or not the information is moving image information (S6). If it is moving image information, the moving image is converted into a still image by the setting means of the in-vehicle information receiving display device (not shown). It is confirmed whether or not it is set to be converted and displayed (S7). If it is not set to still image display, the display restriction unit 16 stores the moving image information in the storage unit 12. It is decided to stop the reproduction by collating with the database, and the control unit 17 is prohibited from displaying the information (S8). If the still image display is set, the moving image information is converted into a still image that is switched at a predetermined time interval by means for converting a moving image (not shown) into a still image, and the control unit 17 converts the still image information. Displayed on the display unit 18 (S9).
[0017]
In addition, it is possible to notify by sound that it has been converted into a still image and displayed as necessary.
[0018]
If the information is not moving image information in step 6, the code detection unit 14 checks whether the information is character information (S10). If the information is character information, the display restricting unit 16 blinks the information. The character information to be checked is collated with the database stored in the storage unit 12, the blinking operation is stopped, and it is determined that the character is enlarged and displayed, and the control unit 17 stops blinking the information. Then, the characters are enlarged and output to the display unit 18 (S11). Further, the voice conversion unit 19 converts the blinking character information into a voice, and the voice output unit 20 outputs the converted voice information (S12). If it is confirmed in step 10 that the information is not character information but graphic information, the display restricting unit 16 collates the blinking graphic information with the database stored in the storage unit 12 to display the graphic. The simplified display is determined, and the control unit 17 stops the blinking of the graphic and then simplifies and displays the graphic on the display unit 18 (S15). As an example of simplification, only the outline of a figure can be displayed.
[0019]
Moreover, it can also notify with sound that the figure was simplified as needed.
[0020]
Hereinafter, the information provided to the in-vehicle information receiving display device uses a language with a display identifier (tag) typified by HTML (Hyper Text Markup Language) used in Internet homepages, data broadcasting in digital broadcasting, etc. A description will be given using an example described as follows. In this case, the detection of the dynamic display is easily possible by decoding the tag. The same applies to the case where the character to be enlarged is determined.
[0021]
If it is determined in step 4 that no importance code has been added, the dynamic display detection unit analyzes the information based on the grammar of the language used to create the information, and blinks the information. It is determined whether display information or moving image information is included (S13). An example of making this determination using grammar will be described using HTML. If there is an element surrounded by <BLINK> and </ BLINK>, which are HTML blinking tags, in the information, that part is the part that is blinked. Further, the file AAA.avi indicated by the tag <IMG DYNSRC = “AAA.avi”> is displayed as moving image information. Therefore, the dynamic display detection unit 15 can confirm the presence or absence of blinking information or moving image information by confirming the presence of these tags.
[0022]
Furthermore, in this case, the range of characters to be enlarged or output is limited to the range enclosed by <H1> to </ H1> of the HTML large heading tag or from <H2> to </ H2 of the middle heading tag. Whether to include the range enclosed by> can be set in advance.
[0023]
If the result of confirmation in step 13 is that neither blinking display information nor moving image information is included, the information is displayed on the display unit 18 without being regulated (S14). When the presence of the blinking information or the moving image information is confirmed, the process proceeds to step 6 and thereafter the processes of steps 6 to 12 are performed. The operation of each of these steps is the same as described above, and a description thereof will be omitted. In the case of information that does not include an importance code and a language with a display identifier, such as a conventional analog television broadcast, display and non-display may be set uniformly.
[0024]
When the importance code is detected in the step 4, the sound conversion means 19 or the sound signal generating means (not shown) is used to notify that the importance code is received with a sound that is less likely to hinder driving. You can also.
[0025]
As described above, when the in-vehicle information receiving and displaying apparatus according to the present invention receives important information while the vehicle is running, it can process and display the information so as not to hinder the driving of the vehicle.
[0026]
In addition, the vehicle-mounted information receiving and displaying apparatus according to the present invention can notify the user of the important information while driving the vehicle by voice so as not to hinder the driving of the vehicle.
[0027]
In the above description, the importance code detection unit detects the importance code, detects blinking information or moving image information in the information, identifies whether the information is moving image, character or graphic information, and character information. However, these can be processed by independent means, and a plurality of these functions can be selectively provided.
[0028]
Moreover, although HTML was used as the language for creating information, the present invention is not limited to this.
[0029]
Furthermore, although the in-vehicle information receiving display device described above integrates the display unit and the audio output unit with the main body unit, there may be an in-vehicle information receiving display device in which these are separated.
[0030]
【The invention's effect】
