BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described in detail below with reference to the drawings. FIG. 1 is an overall view of a display device according to an embodiment of the present invention. The display device body 1 has an IP address as an independent network terminal, and has a control circuit 2 (see FIG.
A detailed description will be given later), a display panel 3 and an input means 4, and a communication line 5 is connected to a communication interface which is a means for receiving electronic information to be distributed, and is connected to the Internet network. There are various types of display devices, from large ones such as outdoor panels to small ones for home use, and the size of the panel changes accordingly. Although it is mainly shared by a plurality of people, it may be intended for an individual. The form of the device is not a stationary type like a personal computer, but is generally a type installed on such a wall surface.

The form of information is also diversified from character information to a still image and a moving image, and a voice is also added to the image, which is generally used. Therefore, as a display device for obtaining such information,
The communication mode is PUSH, which is always connected. In FIG. 1, a surveillance camera 6 is also connected to the local network of the communication line 5 to form a network system, and the indoor or outdoor state can be seen by the display device of the present invention, and the state of a protected person such as an infant can be seen. It is used for watching, external security checks, and other purposes.

Further, the content service information represented by 7 or 8 is received and displayed through the Internet network. These contents are subject to contracts such as charges, and are sent with news and magazines selected according to the user's taste, or with natural scenery, and are sent regularly or irregularly, so the frequency and timing are random. Will be things.

Although not shown in FIG. 1, a server, which is a home server, is installed in the same local network as the display device, and the server selects the obtained information by a predetermined filter means and sends it to the display device. A configuration is also possible.

FIG. 2 is a block diagram of a control circuit according to an embodiment of the present invention, in which a display controller D-CONT 16 and a video RAM V are provided via a CPU 11 and an internal bus 12.
RAM15, PAGE- which is a page memory for receiving information
KIF which is an interface between the RAM 18 and the input means 4
19, COM-IF21 which is a communication interface, ROM 13 which contains a program, R which is an internal memory
The AM 14, the GEN 23 which is a specific information generating means included in the display device, the SP 24 which generates voice and sound, and the TIM 25 which is a timer for performing time information and timer processing are connected.

Then, display data such as an image of the D-CONT 16 is output to the display panel 17 and displayed. Liquid crystal, E, which can be used as a thin display panel
L, plasma display method, etc. can be used. KIF
Reference numeral 19 is connected to a KB 20 which is a keyboard of input means, and 20 performs initial setting of the display device and previous setting of information for selecting reception. In addition to such initial setting, the present invention sets a priority rank for each piece of received information. When there is a plurality of pieces of information to be received at the same time by receiving a plurality of pieces of information by the priority rank, the display device itself processes the display method and the order based on the rank information,
Moreover, the user can also post appropriate information when viewing.

The effectiveness can be exhibited by the processing method of the present invention by simply dividing the priority rank into upper and lower parts such as A and B. Furthermore, finer measures can be taken by dividing the rank into three or more. In addition to the setting of the priority rank, a large amount of received information can be easily processed by supplementarily using a parameter such as a display time during which the display device continues to display the relevant information. For example, one hour,
The display time such as 10 minutes may be set together with the priority rank setting. Further, it is desirable that the display size of such received information is set in page units with respect to the display screen.

In the method of setting the priority rank, the setting is performed for the address of the received information selected according to the user's required field, the amount of information, the density of the content, and the like. Therefore, it is necessary to review the rank based on the experience of the user who uses the received information, and the system can be flexibly changed.

As another setting method, the priority rank and other information can be set by arranging with the transmission source a format in which related information such as the priority rank and display time for the received information is transmitted as a header at the tip of the information. The setting can be automated. Prior to making an agreement, if the concept of deciding information classification and priority is policy-based, it becomes possible to set the priority rank at the transmission source, and it becomes unnecessary to set the reception information from the transmission source on the display device side. . This is very effective when many display devices are installed at a plurality of places and are simultaneously displayed. Further, in such a header system, it is easier to use the above-mentioned server system, and all received information can be unified by the header system.

The communication interface 21 is the communication transmission means 2
Connected to 2. Further, 22 is not limited to a telephone line or a LAN cable, and the display device of the present invention can be constructed by a wireless system by radio or a communication system using a power line. In particular, by using the power line communication system, the power supply required for the display device can be shared with the route taken from the power line outlet, so that the installation of cables is not required and the installation is very easy. Then, unlike in the case of wireless communication, it is not necessary to worry about the problem of the number of terminals accommodated by frequency resources and the electromagnetic wave shield.

The 18 page unit memory has a plurality of page configurations so that a plurality of received information can be stored. However, according to the present invention, even if a plurality of pieces of information are received, the processing proceeds without stagnation, so that a large amount of page capacity is not required blindly. GEN 23 is a specific information generating means by the display device itself, and the information is used outside the setting of the priority rank, and is used as the base display information before the arrival of the received information or when the received information is completely displayed. To do. For example, the time display can be displayed like a wall clock with an image design of a needle type analog clock display.

FIG. 3 is a flow chart of an embodiment of the present invention. As a condition, a processing method using only priority ranks is shown, in which priority ranks are set to two levels of H and L. In the first step, S-31, new data is awaited as new reception information. The base display information is displayed when the power is turned on or at a predetermined start time every day. If there is new data, it is checked in S-32 whether the current display data exists. If there is no current display data, S
The new data is immediately displayed at -33, and if the current display data exists, the priority rank is checked at S-34. If the new data is H rank, the process branches to S-33 and is displayed immediately. If it is not L rank, a plurality of data are displayed simultaneously with the current display data.

If a plurality of data have already been displayed simultaneously and further simultaneous display is difficult, the oldest data is erased in S-35. Regarding the data that fall into the state of simultaneous display, which priority rank was given is ignored and treated as the same rank. In addition, there are several possible simultaneous display methods, for example: * split the screen in a plane * superimpose images such as characters and images * switch screens cyclically in a short time Are listed.

In the method of FIG. 3, the entire display is renewed and the old data is erased by the new data of H rank, and the H rank has a high degree of compulsion. Therefore, it is preferable that the distribution setting of the received information of the H rank is such that the importance is considerably high although the frequency is not so high.

Further, in the method of FIG. 3, by adding a configuration in which the H rank has a display time and setting the display time, it is possible to obtain a blank period in which the display data is lost. Therefore, by performing the base display during this period, it is possible to perform various displays that do not require urgency, display fixed data, and the like. In the case of a wide-area sharing system, it is possible to further display advertisements.

FIG. 4 is a display form diagram supplementing the processing of FIG. The square frame represents the display screen, and shows that the display changes in the order of a to f each time data is added. The alphabet of the symbols means the priority ranks H and L, which are represented by combining the numbers as the order of reception.

First, when new data H1 is received where L1 is displayed in a, the display is replaced by H1 as shown in b according to the priority rank, and the current L1 is discarded. Next, since the received H2 also has a high priority rank, it is replaced with H2 like c. Next, since the new L2 is the lower rank, d is displayed simultaneously with the current H2. The figure simply shows the plane division display. Furthermore, since the next rank is also low as L3, the older H2 such as e is discarded and L2 and L3 are simultaneously displayed. Since H3 is finally received as f, L2
And L3 are abandoned and completely refurbished to H3.

In the case of FIG. 4, the simultaneous display is composed of two data, but it may be three or more. However, the page memory is selected so as not to be difficult to see due to the display capability such as the size and resolution of the display panel so that the page memory does not increase too much.

FIG. 5 is a flow chart showing another embodiment of the present invention, in which the display time is used in addition to the priority rank.
The process of selectively displaying the received information is performed. The destination of the next step in the figure, A to E, will be described with reference to FIG.

In the first step, S-501, new data is awaited as new reception information. When the power is turned on,
Also, while waiting for new data after the display processing of all the display data is completed, the display information of the base is displayed in S-502. If there is new data, S-503
Check the current display data with. If there is no current display data, new data is immediately displayed in S-504, and if there is current display data, S-50.
At 5, the priority rank of the new data and the current display data is checked.

If the new data is higher than the current display data, it is checked in S-506 whether the initial setting of the display device is the erase mode. The definition of this erase mode allows old data and lower data to be saved without discarding as long as the page memory of the display device allows, and the saved data can be displayed at the end of the upper display time. It is a thing.

In the erase mode, the old data, that is, the currently displayed data is discarded in S-507 and the new data is displayed. If the erase mode is not set, the current display data is saved in the page memory in S-508, and is replaced with new data in S-509 for display.

If the erase mode is not set, S-
At 510, it is compared whether it is the same rank as the current display data. If the ranks are the same, the process branches to S-511, and simultaneous display with the current display data is performed.

The fact that the new data is not the same as the current data in S-510 means that the new data has a lower rank than the current data, and whether or not the erase mode is set in the step of S-512. After checking that, S-5
At 15, the current display is continuously displayed. Therefore, it is S- to process the received data that is new data.
514, S515, in the erase mode, S-515
Will discard the new data.

FIG. 6 is a flow chart showing the processing after the display in FIG. B, C, D and E are all shown in FIG.
5 shows the destination after the display processing of A, and A is the starting point of waiting for new data in FIG. S-61 is a process for checking whether or not the latest data has finished the display time when the currently displayed data reaches the set display time. Yes
If it is, the end data is discarded in S-62,
In S-63, it is checked whether there is any saved data to be displayed next. If not, the process branches to S-64 to display the base information. Furthermore, when the display time is also set in the base information, the process returns to A of FIG.

If there is data to be displayed next, S-6
The display process is started in step 5, and the flow returns to the input in step S-61. Here, regarding the display time, there are cases in which the display is finished with the time information set in the original received information as it is, when information with a high priority rank comes during display and it is displayed again after being saved. The rank may be displayed simultaneously. In the latter case, the processing becomes complicated when the time information initially set is concerned, and it is preferable to change the processing to a uniform predetermined time determined by the display device before processing. Also in S-65 of FIG. 6, the display is performed for the predetermined time.
