BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display device and a video supply system.

[0002]

2. Description of the Related Art FIG. 8 is a block diagram showing an example of a conventional video supply system in a broadcasting station. The image supply system 10 includes a primary station 12, a camera 14 (14A, 14B, ...).
...), monitor 16 (16A, 16B, ...), live switcher 18, tally panel 20 (20A, 20B, ...).
…), ID decoder 22, personal computer 24
Etc. Each of the cameras 14 captures an image and outputs an image signal. The monitors 16 are for displaying images from the cameras 14, and are installed in one place. The cameras 14 and the monitors 16 are connected via a switching device (routing switcher) not shown.

The live switcher 18 is for manually giving an instruction to the switching device, and is configured so that which monitor 16 to display the image of each camera 14 can be manually specified. ing. The primary station 12 controls the switching device according to the operation information of the live switcher 18 received via the control bus B to switch and supply the image of each camera 14 to the monitor 16. It is configured. Further, the primary station 12 manages connection information (cross points) indicating a connection relationship between each camera 14 and each monitor 16 connected by the switching device.
Identification names are attached to the camera 14 and the monitor 16, and the connection information is indicated by a combination of these identification names.

The tally panel 20 is disposed adjacent to each monitor 16 and displays the name (description name) of the video signal supplied to the monitor 16. The description name is for each camera 1
It is attached corresponding to 4. The tally panel 20 is

02 and the Chinese character ROM 3404 constitute the font data generating means in the claims. Further, the display unit 3408 constitutes the display means in the claims. Further, the driving unit 3406 constitutes the driving means in the claims.

The operation of the video supply system 10A configured as described above will be described. From the connection information D1 of the first table TB1, the primary station 12 determines the camera 1
The identification name OUT of the monitor 16 corresponding to the identification name IN of No. 4 is read out, and the display data DSP corresponding to the identification name IN of the camera 14 is read out from the second table TB2. Further, the tally panel ID T corresponding to the identification name OUT of the monitor 16 is read from the third table TB3.
Then, the tally panel ID T and the display data DSP corresponding to the tally panel ID T are combined and transmitted to the tally panel 30 via the control bus B.

Each tally panel 30 has its own tally panel ID stored in advance by the controller 32.
T is compared with the transmitted tally panel ID T, and if they match, the transmitted display data D
Judge that the SP is to be displayed on his / her tally panel 30. The control unit 32 then receives the received display data D
Latch 34 of each display device 34 for each SP
Hand over to 02. The latch 3402 receives 1
Display data DSP for characters, that is, a kanji code is latched and input to the kanji ROM 3404. Kanji R
The OM 3404 generates font data from the input Kanji code and supplies it to the drive unit 3406. The display unit 3408 is driven by the driving unit 3406 to turn on or off the LEDs 3412 to display characters. The primary station 12 repeatedly displays the display data DSP on each tally panel 30 by repeating the above-described operation for each connection information D.

As described above, according to the present embodiment, the latch 3402 of the display device 34, the Chinese character ROM 3404, the drive unit 3406, and the display unit 3408.
Since it is configured by being incorporated in a single case 3410, characters can be displayed by inputting a Kanji code such as shift JIS into the display device 34. Therefore, unlike the conventional method, it is not necessary to separately provide an ID decoder for generating font data from a kanji code or a communication line different from the control bus B, which simplifies the configuration and reduces the cost. It is advantageous.

In the present embodiment, the case where one display device 34 displays one character has been described. However, as shown in FIG. 7, the case 3410 may be linearly extended and the display 3408 may be provided for a plurality of characters arranged side by side in the extending direction. In this case, the case 34
Latch 3402 incorporated in 10 and Kanji ROM 3
The same number of 404 and driving units 3406 as the number of display units 3408 may be provided.

The display device 34 is not limited to the tally panel of the image supply system, and it goes without saying that it can be applied to various electronic devices. Further, in the present embodiment, the shift JIS has been described as an example of the kanji code, but what kind of kanji code is used is arbitrary. Further, in the present embodiment, only the point that the Kanji code is transmitted on the control bus B has been described, but other character codes such as ASCII code are communicated on the control bus B in addition to the Kanji code. May be.

[0026]

As described above, according to the display device and the image supply system of the present invention, the characters can be displayed by inputting the Kanji code.
Since it is not necessary to provide a means for generating font data from a Kanji code other than the display device, it is advantageous in simplifying the configuration and reducing the cost.
