Abstract

PURPOSE:To attain direct changeover of an on-air screen not only by cut- changeover but also by wipe changeover. CONSTITUTION:Each video image of video input source signals a-p is displayed on a CRT 12 as an animation picture as a 1/16 division reduced screen. A control section 1 controls a switcher main body section 16 to implement cut- changeover or wipe-changeover for a designated input source based on the designation of the input source by a touch panel 13 and the designation of the cut-changeover or wipe-changeover by a button of an operation console 14. An on-air video image being the result of changeover is displayed on the CRT 12 while being distinguished from other video image.

When the operator touches the touch panel 13 (see FIG. 1) while this button is pressed, the control unit 11 controls the switcher main body 16 to switch the material specified by the operator. will be carried out.

Reference numeral 22 denotes a button for specifying wipe pattern 1 for wipe switching, and when the operator touches the touch panel 13 while this button is pressed, the control unit 11 controls wipe switching in wipe pattern 1 for the material specified by the operator. is performed on the switcher main body 16. 23 is a button for specifying wipe pattern 2 for wipe switching, and when the operator touches the touch panel 13 while this button is pressed, the control unit 1
Wipe pattern 2 of the material specified by the operator according to 1
Wipe switching control is performed on the switcher main body 16. 24 is a button for specifying dissolve for wipe switching; when the operator touches the touch panel 13 while this button is pressed, the control unit 11 causes the switcher main unit 16 to control the dissolving of the material specified by the operator. It will be done.

FIG. 3 is a block diagram showing an example of the configuration of the control section 11. Reference numeral 31 denotes a control processing unit, which determines whether control is to be performed by cut switching or wipe switching based on an interrupt from the touch panel control I/O unit 33 and button status information from the console control I/O unit 34. The material is determined based on the position information input from the touch panel control I/O section 33, and the switcher main body section 16 (see FIG. 1) is controlled via the switcher control I/O section 32. Further, based on the switcher control result information from the switcher control I/O section 32, the video output section 35 is controlled to convert the switcher control result information into a video signal.

Reference numeral 32 denotes a switcher control I/O section, which controls the MK section 41 shown in FIG. 4 based on the control from the control processing section 31.
and the cross point unit 42, and notifies the control processing unit 31 of the control results. 33 is a touch panel control I/O section, which inputs signals from the touch panel 13 to C.

The operation of direct switching by actual cut switching is performed as follows. Switcher main body 16
When the control processing section 31 determines that the operator requests cut switching of the video material signal C while the video bus 1 side is being processed as an on-air line by the MK section 41, the control processing section 31 switches the switcher control I. /O part 32
Direct switching by cut switching is realized by controlling the cross points of the video input material C of the video bus 1 via the video bus 1.

The actual operation of direct switching by wipe switching is performed as follows. Switcher main body 16
When the control processing section 31 determines that the operator requests wipe switching of input material n while the video bus 1 side is being processed by the MK section as an on-air column, the control processing section 31 switches the switcher control I/O The video input material signal n of the video bus 1 and the opposite video bus 2 via the section 32
