This example is a case where the state of FIG. 2 is about to occur at time Tn. That is, when the time Tn is reached, after the entire screen is erased, the element a (not shown in FIG. 4, but the title part 31 managed similarly) is displayed, and then k, k + 1 And k + 2 are displayed. Through this process, the state shown in FIG. 2 is reached.

Next, the operation of the present invention will be described by taking, as an example, a process that becomes the state shown in FIG. FIG.
5 is a flowchart showing the operation of the input processing unit 13. Although the input processing unit 13 has processing corresponding to various commands due to its nature, this flow describes only those parts necessary for explanation of the embodiment of the present invention.

Referring to FIG. 6, input processing unit 13 sets a time counter (tmcnt), which is a counter inside the module, to 0 at the beginning of processing and initializes it, and stores the current time (curtime) at that time inside the module. (Step number 11, abbreviated as # 11 in the figure, and the steps are omitted below). The current time is set by the system call
It can be obtained by inquiring. A display process is performed by giving the value of the time counter (currently 0) to make the screen an initial display (number 12). When the display is completed, the time counter is updated by the unit time (number 13). Then, it is confirmed whether or not there is an input in the input queue buffer 11 (No. 14). If there is an input, the input is taken out, interpreted and branched to each command processing function (No. 14, N, No. 15, No. 1
6).

If there is no input, the present time is compared with the start time compared with the previous time (number 19). If the difference is equal to or greater than the time counter, it is determined that the time to be processed has been reached and the display processing is performed. Do. That is, the contents of the current time counter are passed to the display processing to perform the display processing (number 20), and after the processing, the time counter is updated to the next time (number 21). If the time to be processed has not been reached, the input is confirmed again, and the processing up to this point is looped thereafter (N in number 19, number 14).

Next, the operation of the display processing unit 14 will be described with reference to FIG. It is assumed that the display processing unit 14 specifies the time Tn as input information.

Referring to FIG. 7, first, it is searched whether or not a process relating to a designated time is present in the process list (number 31). If there is, a process counter (cnt) is found.
Then, initialization of the processing record pointer (rp) is performed (Y at number 32, numbers 33 and 34).

Next, if there is a processing content in the processing list (Y in number 35), the processing content is read from the record in the processing list indicated by the processing record pointer (number 36), and the content is analyzed. Branching is performed for each process (number 37 to number 39).

After each processing is completed, the processing counter cnt is decremented (number 40), and the processing record pointer rp is updated to the next record (number 41). In this case, since the processing as shown in FIG. 5 is described corresponding to the time Tn, first, the erasing processing is performed (No. 38), and then the display processing of each element is performed (No. 39).

FIG. 8 is a flowchart showing the contents of the element display processing. The element display process is to display the element I
D shall be taken. First, a record related to the specified element ID is searched from the component list (number 5).
1). If a record exists, the process branches depending on the contents of the data status flag (flg field) of the record (Y in number 52, number 53). If the content of the flag is "M", since the data exists in the memory, the address of the data entity stored in the DATA POINTER field of the component list is set to the pointer p (number 57). If the content of the flag is "F", since the data exists on the file, the file is accessed based on the file name stored in the DATA POINTER section of the component list, and is expanded on the memory (number 54), the developed address is set in the pointer p (N at number 55, number 56).

When the setting of the data pointer is completed, position and size information is obtained from the corresponding record (number 59), and data type information (“type”) of the same record is obtained.
Branching to the actual display processing for each data type according to the contents of. That is, the process branches to a character display process (number 63) for character display, and to a moving image display process (number 64) for moving image display. The screen state as shown in FIG. 2 for the time Tn is obtained by the processing described above.

Now, the image portion of the car (element ID = k +
When displaying 2), access to a file containing data (the file name is “XXXXXPRM.PMG” from the component list in FIG. 4) due to a timeout due to network disconnection or line overload or loss of file data. Failed. In this case, a failure is detected in the processing status check after the file access processing in the flowchart of FIG. 8 (Y at number 55), and “NULL” is set to the data pointer (number 5).
8). After obtaining the position and size information of the element,
If the data pointer p is "NULL", an area is displayed (number 62), and the normal processing is thereafter terminated.

FIG. 9 is a flowchart showing the contents of the area display process indicated by the number 62 in FIG. It is assumed that the area display process takes the element ID shown in FIG. 4 as input data.

First, a record in the component list relating to the designated element ID is searched (number 71), and if it exists, the position and size of the corresponding element are obtained from the record (Y for number 72, number 73). ). A rectangle indicating the area of the data is drawn according to the information (number 74). Next, a record in the auxiliary information memory 19 relating to the specified element ID is searched (number 7).
5) If it exists, the address and the data length of the auxiliary information assigned to the corresponding element are acquired from the record (Y at number 76, number 77). The display position of the auxiliary information is determined (No. 78), and the process branches to each display process depending on the data type of the auxiliary information (No. 7).
9 to number 81).

FIG. 10 is a diagram showing an example of auxiliary information in the auxiliary information memory 19. Referring to FIG. 10, auxiliary information memory 19 stores an element ID and a data type (ty) of auxiliary information.
p), a data section (len), a table section for managing a data storage address (adr), and a data section (dat) for storing actual data contents.

In this case, for the element “k + 2”,
The data type is text data (“txt”) set as auxiliary information, the length is 22 bytes, and the storage destination address is p. After referring to such auxiliary information, character display processing is performed because the auxiliary information is text data (number 80). As a result, the screen is shown in FIG.
As shown in (2), the part displaying the moving image is replaced with a rectangle indicating the area and a comment sentence as auxiliary information and displayed.

As is clear from the above description,
The auxiliary information may be data managed in the auxiliary information memory 19, for example, when image data is managed (that is, when "img" is recorded in the data type field of the corresponding record in the auxiliary information memory 19). ), The image display processing in FIG. 9 may be performed (number 81). Also, as is obvious, the system stores in advance the file names managed in the component list of each element without having the operator separately set the auxiliary information managed in the auxiliary information memory 19. By doing so, the file name can be displayed as auxiliary information.

Further, by setting in advance the image data for each data type managed in the component list, it is possible to display the prescribed image data without any special input by the operator.

(2) Second Embodiment In the first embodiment, the present invention is applied when a processing error occurs as shown in FIG. 9, but in the second embodiment, the present invention is applied as a simple display mode by an operator. Is set.

FIGS. 12 and 13 are flow charts for explaining the operation of the second embodiment. Referring to FIGS. 12 and 13, the processes from number 91 to number 99 are the same as those in the first embodiment shown in FIG. 8, and the description of the processes up to that will be omitted. In the second embodiment, it is checked whether or not the display mode is the simple display mode before performing the actual display processing with the number 100. If the display mode is the simple display mode (Y at number 100), the area display processing is performed unconditionally (number 103). If the motor is not a simple display motor (N in number 100), the same processing as in the first embodiment is performed, and the processing branches depending on the data type information of the record (numbers 104 and 105).

(3) Third Embodiment Next, a third embodiment of the present invention will be described. The third embodiment is an embodiment in which the present invention is applied when display of data of an unprocessable (incompatible) data type is expected. Here, the number 6 in FIG.
An example in which the present invention is applied to the moving image display processing appearing in No. 4 will be described.

In the moving image display processing, the main processing is to provide data to the moving image processing section 18 to display a moving image. However, if the data is of a data type that cannot be processed, instead of displaying a moving image, the area display processing according to the present invention is performed.

FIG. 14 is a flowchart showing the contents of the moving image display processing. Referring to FIG. 14, in the moving image display processing, it is assumed that a display position and an address where data to be displayed exist are specified as inputs. First, the data header portion at the head of the data of the designated address is analyzed (number 11
1) Check whether the moving image data is of a data type that can be processed (number 112). If the type can be processed, the processing of the moving image is requested to the moving image processing unit 18, but if the processing cannot be performed, the processing is not performed but the area display processing according to the present invention is performed (number 114). With such processing, even when data of an incompatible data type cannot be processed, it is possible to indicate an area where the data exists and to indicate the content by auxiliary information.

In the third embodiment, the basic structure of the document display device is the same as that of the first embodiment, and the description is omitted.

(4) Fourth Embodiment Next, a fourth embodiment of the present invention will be described. The fourth embodiment is an embodiment in which the present invention is applied to recover the time delay when a delay occurs due to processing in the process of changing the display content according to the time change. .

FIGS. 15 and 16 are flowcharts showing the operation of the input processing unit 13 to which the above-mentioned application is applied. This is basically the same as that shown in FIG. 6 of the first embodiment (Nos. 121 to 129), but before actually performing the display processing, the difference between the current time and the time counter is obtained, and the difference is determined in advance. The number 130 for checking whether the number is larger than the threshold value is different. If it is less than the threshold value, display processing is performed as it is (N in number 130, number 135). If it is more than the threshold value, it is determined that a time delay has occurred, and the display mode is set to simple mode (Y, number 130 in number 130). No. 131) and display processing is performed (No. 132). At this time, the display processing is the processing of FIGS. 12 and 13 of the second embodiment, in which the simple mode is detected and the area display processing of the present invention is performed. After the display processing, the display mode is returned to the original state and returns to the normal processing (No. 133).

In the fourth embodiment, since the processing time in the area display processing can be shorter than that in the normal display processing, the time recovery of the entire processing can be realized when a time delay occurs.

In the fourth embodiment, the basic configuration of the document processing apparatus is the same as that of the first embodiment, and a description thereof will be omitted.
