BACKGROUND OF THE INVENTION
The present invention relates to a display device for displaying various information sent by a communication means every moment.
[0002]
[Prior art]
2. Description of the Related Art In recent years, display terminals that display information from the outside on a wall or the like have been used with the thinning of display panels. For example, as shown in Japanese Patent Laid-Open No. 7-44142, an information display device having input means for receiving information from a dedicated terminal.
[0003]
In the above-described conventional example, a method has been adopted in which two input means are provided so as to be able to cope with the case where there are two terminals that send information, and switching is performed in time so that both pieces of received information can be displayed.
[0004]
However, with the development of digital technology, various digital information contents have been distributed through the Internet network, and a display device capable of effectively displaying a variety of randomly entering information is required. It is becoming impossible to cope with this method.
[0005]
[Problems to be solved by the invention]
The present invention has been made in view of the above problems, and an object of the present invention is to realize a display device that can receive a large amount of latest information from a transmission source specialized in a specific genre or the like and can provide it to users.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a display device comprising: electronic information receiving means by distribution; display control means; display information storage means having an amount of information for at least one screen; and a display panel. Rank setting means for setting a priority rank in advance to the reception information to the reception means is further provided, and the display control means selectively selects the reception information distributed at random on the display panel based on the setting of the rank. The display is performed.
[0007]
Still further, the display control means selectively causes the display panel to display received information distributed at random based on the priority rank setting and time information.
[0008]
In addition, when a plurality of pieces of received information having the same rank exist at the same time, the display form on the display panel is a simultaneous display such as screen division, superimposition, and sub-screen display.
[0009]
In addition, when reception information of different ranks exists at the same time, a method of displaying the reception information of higher rank and discarding the reception information of lower rank, and the reception information of higher rank is the time setting And displaying the low-rank reception information for a predetermined time after the display is completed by the means.
[0010]
In addition, after all the reception information display based on the settings of the rank setting means and the display time setting means is finished, the possessed information of the display device itself or information from a specific transmission source is used as the base display information. And
[0011]
In addition, when the display priority rank or the display time is set in advance in the reception information, it depends on the address of the transmission source of the reception information.
[0012]
In addition, when the display priority rank or the display time is set in advance in the reception information, the display priority rank or the display time data added and sent to the header of the reception information is used.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below in detail 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 main body 1 has an IP address as an independent network terminal, and includes a control circuit 2 (detailed in FIG. 2), a display panel 3 and an input means 4, and a communication interface which is a means for receiving distributed electronic information. The communication line 5 is connected to the Internet network. There are various types of display devices, such as outdoor panels, which are large, and small ones for home use. Accordingly, the size of the panel also changes. Although it is mainly shared by a plurality of people, it may be intended for individuals. In general, the apparatus is not a stationary type such as a personal computer, but is installed on such a wall surface.
[0014]
The form of information is also diversified from character information into still images and moving images, and is generally used with sound added to the images. Therefore, a display device that obtains such information has a communication mode called PUSH by constant connection. 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. Used for watching, security check from outside and other uses.
[0015]
Further, content service information represented by 7 or 8 is received and displayed through the Internet network. These contents are contracted for fees, etc., and they are various news and magazines selected according to user's preference, or natural scenery, and are updated regularly or irregularly, so the frequency and timing are random It will be a thing.
[0016]
In addition, although not shown in FIG. 1, a network configuration in which a server as 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 is also considered. It is done.
[0017]
FIG. 2 is a block diagram of a control circuit according to an embodiment of the present invention. CPU 11, D-CONT 16 which is a display controller, VRAM 15 which is a video RAM, PAGE-RAM 18 which is a page memory for received information, input via an internal bus 12 KIF 19 that is an interface of means 4, COM-IF 21 that is a communication interface, ROM 13 in which a program is built, RAM 14 that is an internal memory, GEN 23 that is a specific information generating means included in the display device, SP 24 that generates sound and sound, A TIM 25 that is a timer for performing time information and timer processing is connected.
[0018]
Then, display data such as an image of the D-CONT 16 is output to the display panel 17 and displayed. As a display panel method, a liquid crystal display, an EL display, a plasma display method, or the like that can be thin-shaped can be used. The KIF 19 is connected to the KB 20 which is a keyboard of the input means, and 20 performs initial setting of the display device and previous setting of information for selecting reception. In addition to such initial settings, the present invention sets priority ranks for individual received information. When there are multiple pieces of information that you want to display at the same time after receiving multiple pieces of information according to the priority rank, the display device itself processes the display method and order based on the rank information and is also appropriate for the user to see. Posts can be made.
[0019]
Even if the priority rank is divided into upper and lower parts such as A and B, the effectiveness can be exhibited by the processing method of the present invention. Furthermore, more detailed measures can be taken by dividing into three or more ranks. In addition to setting the priority rank, a lot of received information can be easily processed by using a parameter such as a display time during which the display device continues to display the corresponding information. For example, the display time such as 1 hour or 10 minutes may be set together with the priority rank setting. Further, it is desirable to set the display size of such received information in units of pages for the display screen.
[0020]
In the priority rank setting method, settings are made 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 using the received information, and the system can be changed flexibly.
[0021]
Another setting method is to automate the priority rank and other settings by negotiating with the sender the format for transmitting the related information such as the priority rank and display time to the received information as a header at the head of the information. can do. Prior to the arrangement, if the concept of determining the classification and priority of information is established, it is possible to set the priority rank at the transmission source, and it is not necessary 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 locations and simultaneously displayed. In addition, it is easier to use the aforementioned server method for such a header method, and all received information can be unified by the header method.
[0022]
The communication interface 21 is connected to the communication transmission unit 22. The display device 22 is not limited to a telephone line or a LAN cable, and the display device of the present invention can also be constructed by a wireless wireless system or a communication system using a power line. In particular, by using the power line communication method, the power supply required for the display device can be shared with a route for taking it from the power line outlet, so that installation of cables and the like is not required and installation is very easy. And it is not necessary to be concerned about the problem of the number of terminals accommodated by frequency resources or radio wave shielding as in the case of wireless.
[0023]
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 process proceeds without stagnation, so that a large amount of page capacity is not required.
GEN 23 is specific information generating means by the display device itself, and this information is used outside the priority rank setting, and is used as base display information before reception information arrives or when reception information is exhausted. To do. For example, the time display can be displayed like a wall clock with the image design of a hand analog clock display.
[0024]
FIG. 3 is a flowchart of the embodiment of the present invention. As a condition, a processing method using only the priority ranks with the priority ranks of two stages of H and L is shown.
In S-31 which is the first step, new data is awaited as new reception information. Base display information is displayed when the power is turned on or at a predetermined start time every day. If there is new data, the presence or absence of the current display data is checked in S-32. When there is no current display data, new data is immediately displayed at S-33, and when there is current display data, the priority rank is checked at S-34. If the new data is H rank, the display branches immediately to S-33, and if it is L rank, a plurality of data are simultaneously displayed together with the current display data.
[0025]
If a plurality of data has already been displayed at the same time and further simultaneous display is difficult, the oldest data is erased at S-35. For data that has fallen into such a simultaneous display state, the priority rank is ignored and treated as the same rank. In addition, there are several methods for simultaneous display. For example, * dividing the screen in a plane * superimposing images like characters and images * cyclically switching screens in a short time Are listed.
[0026]
In the method of FIG. 3, the entire display is renewed and the old data is erased with the new data having the H rank, and the H rank has a strong degree of forcing. Therefore, it is preferable to set the distribution for the received information having the H rank so that the degree of importance is considerably high although the frequency is not so high.
[0027]
Further, in the method of FIG. 3, if a configuration in which the H rank has a display time is added and the display time is set, a blank period with no display data can be obtained. Therefore, by performing the base display during this period, various displays that do not require urgency, posting of fixed data, and the like can be performed. In the case of a wide-area sharing system, it is also possible to display an advertisement or the like.
[0028]
FIG. 4 is a display form diagram supplementing the processing of FIG. A square frame represents a display screen, and shows how the display changes in order from a to f each time data is added. The alphabet of a symbol means the priority ranks H and L, and represents the combination of numbers as the order of reception.
[0029]
First, when new data H1 is received at a place where L1 is displayed in a, the display is replaced with H1 as shown in b by the priority rank, and the current L1 is discarded. Next, since the received H2 has a high priority rank, it is replaced with H2 as shown in c. Next, since new L2 is a low rank, d is displayed simultaneously with the current H2. The figure shows the plane division display in a simplified manner. Furthermore, since L3 is also in the lower rank, the older H2 is discarded as shown in e, and L2 and L3 are displayed simultaneously. Finally, when H3 is received as f, both L2 and L3 are discarded and the entire surface is renewed to H3.
[0030]
In the case of FIG. 4, the simultaneous display is composed of two data, but may be three or more.
However, the range is selected so as not to be difficult to see depending on the display capability such as the size and resolution of the display panel, so that the page memory does not increase too much.
[0031]
FIG. 5 is a flowchart showing another embodiment of the present invention, in which display processing for selective reception information is performed using a display time in addition to a priority rank. The destinations of the next steps in the figure, A to E, will be described in FIG.
[0032]
In the first step S-501, new data is awaited as new reception information. When the power is turned on and while waiting for new data after all display data has been displayed, the base display information is displayed in S-502. If there is new data, the presence or absence of the current display data is checked in S-503. If there is no current display data, the new data is immediately displayed in S-504. If the current display data exists, the priority rank between the new data and the current display data is checked in S-505. .
[0033]
If the new data is higher than the current display data, it is checked in S-506 whether or not the initial setting of the display device is the erase mode. This definition of erasure mode allows old data and lower-order data to be stored without being discarded as long as the page memory margin of the display device permits, and the stored data can be displayed at the end of the upper display time. Is.
[0034]
If it is the erasing mode, the old data, that is, the currently displayed data is discarded in S-507 and the new data is displayed. If not in the erase mode, the current display data is saved in the page memory in S-508 and then replaced with new data in S-509 for display.
[0035]
If not in the erase mode, it is further compared in S-510 whether the rank is the same as the current display data. If they are the same rank, the process branches to S-511, and the current display data is displayed simultaneously.
[0036]
If it is not the same as the current data in S-510, it means that the new data has a lower rank than the current data, and it is further checked in step S-512 whether it is in the erase mode. Later, in S-515, the current display is continuously displayed. For this purpose, the received data which is new data is processed in S-514 and S515, and in the erase mode, the new data is discarded in S-515.
[0037]
FIG. 6 is a flowchart showing the processing after the display in FIG. B, C, D, and E all indicate destinations after the display process of FIG. 5, and A is a starting point for waiting for new data in FIG. S-61 is a process for checking whether the latest data has finished the display time when the currently displayed data has reached the set display time.
If Yes, the end data is discarded in S-62, and it is checked in S-63 whether there is any stored data to be displayed next. If it does not remain, it branches to S-64 and shifts to display base information. Further, when the display time is set for the base information, the process returns to A in FIG.
[0038]
If data to be displayed next remains, the display process is started in S-65, and the process returns to the input in step S-61. Here, in the handling of the display time, when the display is completed as it is with the time information set in the original received information, or when information with a high priority rank comes and is temporarily saved during display, it is displayed again. It may be displayed simultaneously as a rank. In the latter case, the processing becomes complicated depending on the initially set time information. Rather, it is preferable to change the processing to a uniform predetermined time determined by the display device. Also in S-65 of FIG. 6, the display for the predetermined time is performed.
[0039]
【The invention's effect】
As described above, according to the present invention, in a display device that displays externally received information under installation conditions that can be applied to a wall surface, a plurality of data and randomly received information are processed, and sequential display is automatically performed. It becomes possible.
[0040]
According to the present invention, the display form of the processed result takes the importance of the received information into consideration, and can give the user high convenience.
[0041]
Further, according to the present invention, it is possible to secure a display free time without losing information on the received information, and display such as a nearby monitoring camera, a clock display, or an advertisement as the base information in the free time. It becomes easy.
