Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a control device for controlling the transmission order of programs such as news and commercials that are edited in advance at a broadcasting station.

This type of program transmission order control device or program progress control device is computerized and is configured to sequentially transmit program contents edited in advance from a plurality of VTRs under computer control. Furthermore, in order to monitor the progress of programs, still images representing individual programs are displayed on the monitor screen in the order in which they are broadcast.

When operating such a program progress control device,
The scheduled transmission order may be rearranged or another program may be inserted. Such switching and interrupting operations are performed by key operations while looking at the computer display, so the operations are complicated and prone to erroneous operations. In particular, there is a considerable need to quickly change the order of a program or interrupt a program while it is on air, but erroneous operations may impede the progress of the program.

For example, in a conventional interpolation operation, when the display shows a transmission order such as 1, 2, 3, 4, 5, etc., to insert 7 between 3 and 4, , first input "3" and "4" using the keys,
Next, operate the "insert" key, then key in "7", and then operate the "execute" key. As a result,
The sending order is 1, 2, 3, 7, 4, 5...

The operation procedure for switching or interrupting as described above is very complicated and is prone to erroneous operation.

In view of this problem, it is an object of the present invention to provide a program delivery order control device that has simple operating procedures, is extremely visually clear, can be operated quickly, and has extremely few erroneous operations.

The program transmission order control device of the present invention is a device for setting the program transmission order on the monitor screen, and is a device for setting the program transmission order on the monitor screen. It is equipped with a screen buffer memory that stores the data arrangement. Further, as operation means, an insertion key 15 for inserting an interrupt in the program transmission order, a cursor shift key 16 for moving a cursor on the screen,
17 and an input key 19 for specifying the number. Furthermore, a cursor pointer memory is provided for displaying an intermediate position between the numbers in the display number sequence on the screen with a cursor as an interpolation position based on the operation of the cursor shift key when the insert key is operated. There is. A memory control means such as the microprocessor 6 sequentially shifts the number data in the screen buffer memory in the direction of arrangement so that the screen buffer memory corresponding to the insertion position indicated by the cursor pointer memory becomes empty. , insert the data of the number specified by the above-mentioned number input key into the formed space. Based on the number arrangement in the screen buffer memory, the transmission order of programs corresponding to each number is controlled.

According to this configuration, the order for insertion or replacement is specified by moving the cursor to the interpolation position, so the operation is simple and visually clear, and erroneous operations are reduced.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of the main parts of an image transmitting device for a broadcasting station using a data display device according to the present invention. In FIG. 1, video information to be transmitted is recorded on a magnetic disk 4 in the form of still images.
The read output of the disk 4 is sequentially written to the video memory A1 and the video memory B2 via the magnetic disk controller 5. Video memory A,
The outputs of B are alternately selected by the on-air switch 3 and displayed on the monitor as an image representative of the video information to be sent out. Furthermore, video memory A
When the contents of the first image are being transmitted as on-air output, the next image is stored in the other video memory B2, and the contents are displayed on another monitor through the switch 3 as the next output. Next, when the output of video memory B2 is selected as on-air output, new information is written to video memory A1.

Video memory A, B, on-air output switch 3
and the magnetic disk controller 5 are connected to the bus 7, respectively.
is combined with the microprocessor MPU6 through
It is controlled by commands from this MPU6. A keyboard 9 is connected to the bus 7 via an input/output section I/O 8 , and a character monitor 11 is connected via a display controller 10 . Further, system operation commands can be given using the keyboard 9, and data such as the order of image sending information is displayed on the character monitor 11. Note that the bus 7 is connected to an image sending device including a plurality of VTRs,
Video information such as news and commercials corresponding to the still image selected by the apparatus shown in FIG. 1 is broadcast on air.

2 is a plan view showing a main part of the keyboard 9 shown in FIG. 1, and FIG. 3 is a partial front view showing the display contents on the screen 22 of the monitor 11. On the monitor screen 22, the order of the output images determined by the input from the numeric keypad 19 in FIG. 2 is displayed as 0, 1, 2, . . .
It will be displayed like this. To change the sending order, first press the insert key 15 in FIG. Move it to the right or left. For example, to insert the third image between the fifth image and the sixth image, move the cursor 23 to the position shown in FIG. Next, use the numeric keypad 19 to specify the image number to be interpolated (“3” in the above example) and press the execution key 18. …1, 2, 4, 5, 3,
The sending order is changed as in 6, 7, . . . .

By providing such a configuration and function, interpolation work or order rearranging work becomes extremely simple, and erroneous operations are reduced.

Next, information processing for realizing the above-mentioned functions will be explained with reference to flowcharts shown in FIGS. 4A to 4I. The MPU 6 shown in FIG. 1 is provided with the following memories or registers.

Screen buffer......0 to 9 Cursor pointer...0 to 10 Numeric keypad No....0 to 9 Screen pointer...0 to 9 The screen buffer stores the image sending order as shown in Figure 3. . The cursor pointer is used to indicate the cursor position on the monitor 22. The numeric keypad No. memorizes the input from the numeric keypad 19, and the image pointer is used to indicate the position of each data on the monitor 22.

As shown in FIG. 4A, first, in step 30, the screen buffer is set to 0 to 9, and the cursor pointer is set to 0. Next, the screen output subroutine shown in FIG. 4I is executed at step 31. In this subroutine, as shown in FIG. 4I, the screen pointer is first set to 0 in steps 63 and 64, and a space (blank) is displayed.
Next, in steps 65 to 68, the screen pointer changes from 0 to 9, and the contents of the screen buffer pointed to by the screen pointer are sequentially displayed with spaces inserted. Next, in step 69, a cursor is displayed at the position of the cursor pointer (0 at this point) x 2.

When the screen output subroutine is completed, "10" is entered in the numeric keypad number memory in step 32, and
Next, key operation detection in steps 33-37 is performed. When the insert key is pressed (step 33) and the cursor shift key “→” is pressed, step 34
The process branches to FIG. 4B, and 1 is added to the cursor pointer (step 38). If the cursor pointer is 10 or less, this is detected in step 39, and a cursor is displayed at the position of 2 times the cursor pointer ("1" at this point) in step 41. That is, the cursor is moved between "1" and "2" in FIG. Each time the "→" key is pressed, the cursor is sequentially moved to the right. Note that the cursor pointer is set to any value from 0 to 9, and twice that value is displayed as the cursor position, so the cursor position is displayed in the middle of the sending image numbers displayed on the screen 22.

When the cursor pointer advances to a value of 10, the cursor pointer is reset to 0 by step 40.

When the "←" key is pressed, the process branches from step 35 to FIG. 4C, and the cursor is sequentially moved to the left through steps 42-45. Note that when the cursor pointer reaches 0, it is reset to 10 in step 44.

By the above operations, the cursor is set at the insertion point between images No. 5 and No. 6, for example, as shown in FIG.

Next, when the numeric keypad 19 is operated to specify the insertion image number (for example, the third image), the process branches from step 36 in FIG. 4A to step 46 in FIG. is memorized. Next, when the execution key is pressed, the process branches from step 37 in FIG. 4A to FIG. 4E. If the numeric keypad number is 10 or less, this is determined in step 47, and the screen pointer is set to 0 in step 48. .
Next, in steps 49 and 50, the screen pointer value is increased in steps of 0, 1, 2, etc. until the image number in the screen buffer indicated by the screen pointer value becomes equal to the input numeric keypad number. will be advanced.

When the value of image No. "3" and the screen pointer become equal, the process branches from step 49 to step 51, and the cursor pointer and screen pointer (or screen pointer +
1), the cursor pointer and screen pointer are compared in size in step 52. Note that when the cursor pointer = screen pointer (or screen pointer + 1) in step 51 (in the above example, when the screen pointer, that is, the image number entered by the key is between 5 and 6, there is no need for interpolation, so the program is key determination 34~ in Figure 4A.
Return to 37.

At step 52, if the cursor pointer<screen pointer, the process branches to FIG. 4F, and if vice versa, the process branches to FIG. 4G. In the above example,
Since the cursor pointer is 6 and the screen pointer, that is, the image number to be inserted is 3, the process branches to step 56 in FIG. 4G. In this step, the contents of the image buffer indicated by the screen pointer +1 (i.e. No.
4) is placed in the screen buffer position (position No. 3) indicated by the screen pointer. As a result, the screen buffer arrangement is 0, 1, 2, 4, ×, 5,
6... becomes. Next, in step 57, 1 is added to the screen pointer, and the above-described sequential processing is repeated until the screen pointer=cursor pointer becomes 1. The screen buffer arrangement is 0, 1, 2, 4, 5,
When x, 6 is reached, the process branches from step 58 to step 59 in FIG. 4H, and the numeric keypad number is placed in the screen buffer indicated by the screen pointer. This changes the array to 0, 1, 2, 4, 5, 3, 6, 7...

If the cursor pointer is smaller than the screen pointer in step 52 of FIG. 4E, the process of FIG. 4F is performed, and in steps 53 to 55, a forward feed operation in the opposite direction to that of FIG. 4G is performed.

When the interpolation operation is completed in step 59 of FIG. 4H, the screen output subroutine of FIG. 4I is then called and the modified data arrangement is displayed on the monitor. Next, in step 61, the numeric keypad number memory is reset to "10", and all processing is completed.

In the above-described embodiment, the data is arranged in the horizontal direction of the monitor screen, but the present invention can also be applied to data arranged in the vertical direction of the screen or arranged in a matrix.

As described above, according to the present invention, the program delivery order can be changed or the order for interpolation can be specified by a simple operation of moving the cursor on the monitor screen to the interpolation position. Misoperations are reduced and quick operations are possible.
In particular, since the operations are visually extremely clear, it is now possible to perform operations such as replacing or interrupting a program while it is on air without making any mistakes, allowing programs to proceed smoothly when immediacy is required, such as in news programs. become.
