Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video effect device, and more particularly to a video effect device for producing a television broadcast program by appropriately switching and selecting a video material or an effect screen signal.

[0002]

2. Description of the Related Art Conventionally, in this type of image effect apparatus, a plurality of image materials or effect screen signals [for example, a wipe composition screen, a chroma key composition screen, a DVE (Digi) are used.
TalVideo Effect) Composite screen, superimposed screen, etc., and composite screens thereof, etc.] By pressing a plurality of rows of push button switch groups corresponding to each of them, it is possible to select from the plurality of video materials or effect screen signals. ing. A method of changing the screen by applying an effect such as a fade or a wipe to the selected video signal according to a fader instruction is used.

That is, as shown in FIG. 4, the above-mentioned video effect apparatus has push button switches 41-1 to 41-n, 42.
-1 to 42-n, fader levers 43 and 44, switching device 45, input terminals 46-1 to 46-n, and mixing device 8
And an output terminal 9.

Push button switches 41-1 to 41-n, 42
-1 to 42-n are arranged in the same number as the input terminals 46-1 to 46-n corresponding to the fader levers 43 and 44, respectively. Push button switches 41-1 to 41-n, 42-1
To 42-n, the video material or the effect screen signal from the input terminals 46-1 to 46-n corresponding to the pressed switch is selected by the switcher 45, mixed by the mixer 8 and output from the output terminal 9. To be done.

For example, the operator pushes the push button switch 41.
When -1 and the push button switch 42-n are pressed, the cross points corresponding to the push button switches 41-1 and 42-n of the switching unit 45 are turned on, and the video material input from the input terminal 46-1 or Effect screen signal and input terminal 4
The video material or the effect screen signal input from 6-n are output to the mixing device 8, respectively.

In the mixer 8, the video material or effect screen signal input from the input terminal 46-1 selected by the switch 45 and the video material or effect screen signal input from the input terminal 46-n are fed to the fader lever. Effects such as fading or wiping are added in accordance with the operation of 43 and 44 (movement in the direction of the arrow) to mix, and the mixed video signal is output from the output terminal 9.

As for the technique of mixing the video signals of this kind and imparting the special effect, there are the technique disclosed in Japanese Patent Publication No. 61-11516 and the technique disclosed in Japanese Patent Laid-Open No. 2-230878. is there.

[0008]

In the above-mentioned conventional image effect apparatus, a plurality of rows of switchers and a push button switch group which controls the switchers and corresponds to the fader lever are arranged in association with each other. Therefore, when there are many video materials or effect screen signals to be input from the input terminal group, the input terminals and push button switches must be arranged correspondingly.

When a push button switch corresponding to a large number of video materials or effect screen signals is operated, it is not possible to support a highly responsive broadcast program in which the video materials or effect screen signals must be selected instantaneously.

In addition, television broadcast programs include a wide variety of broadcast programs such as news transmission programs and relay programs, and the video materials handled differ depending on the contents of these broadcast programs. Therefore, in order to support all broadcast programs. Must deploy multiple pushbutton switches.

In this case, although each broadcast program handles only a small number of video materials, a limited number of video materials are selected from among a large number of push button switches arranged to correspond to all broadcast programs. You have to choose only
The operability of the selection operation of the image material or the effect screen signal is deteriorated.

Therefore, an object of the present invention is to solve the above-mentioned problems, to be able to sufficiently cope with a broadcast program having a high responsiveness, and to improve the operability of the selection operation of the image material or the effect screen signal. An object is to provide a video effect device.

[0013]

A video effect apparatus according to the present invention comprises a plurality of push button switches for designating any two of a plurality of video materials and effect screen signals, and pressing of the push button switches. In response to the selection means for selecting two from the plurality of video materials and effect screen signals, and two of the plurality of video materials and effect screen signals selected by the selection means from the fader. A video effect device including mixing means for mixing according to a signal, wherein the video material to be selected by the selecting means and switching data for instructing an effect screen signal and the video material to be selected by the selecting means. And storage means for storing the name of the effect screen signal in association with each of the plurality of push button switches, and a plurality of push button switches provided corresponding to each of the plurality of push button switches. A plurality of display means for displaying the names of the video material and the effect screen signal pre-assigned to, and the selection based on the switching data read from the storage means in response to the pressing of the plurality of push button switches. Control means for controlling the selecting operation of the means.

In addition to the above configuration, another video effect apparatus according to the present invention includes switching data for designating the video material and effect screen signal according to a preset program transmission procedure and a name corresponding to the switching data. It comprises a supply means for supplying to the storage means.

[0015]

[Function] The switch data for instructing the video material or effect screen signal to be selected by the switch and the name of the video material or effect screen signal corresponding to the switch data are stored in the storage device in association with each push button switch. Remember.

Further, the names of the video materials or effect screen signals pre-assigned to the respective push button switches are displayed on the material display, respectively, and the switching data read from the storage device in response to the depression of each push button switch is displayed. The switching control circuit controls the switching operation of the switching device.

As a result, even if there are many video materials or effect screen signals, only the video materials or effect screen signals limited by the contents of the broadcast program are displayed on the material display unit, and the displayed video materials or effect screen signals are displayed. The push button switch can be selected while confirming the name.
Therefore, it becomes possible to fully correspond to highly responsive broadcast programs,
The operability of the selection operation of the image material or the effect screen signal is improved.

Further, when the video effect device is controlled by the automatic sending control device, since the push button switch corresponding to the material display device displaying the name of the video material or the effect screen signal instructed by the automatic sending control device is turned on, It is convenient when operating automatic control and manual control in parallel.
