Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a video program production janitorial console.

Traditionally, when producing television broadcast programs outside of a broadcasting station, a relay van full of adjustment equipment for broadcasting was used to do so, but with the recent diversification of broadcast programs, This creates places and other conditions where it is not possible.

Furthermore, this diversification phenomenon has also created a situation where film editing or program editing using a single handy TV camera is no longer satisfactory. SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a simple adjustment console that has excellent maneuverability that can meet the recent demands for program diversification, and has technical effects comparable to those of a relay van.

However, the present invention compactly aggregates sufficient editing and adjustment equipment necessary for video program production, maintains a certain level of technical effectiveness, and improves its mobility. The switch group and monitors are arranged in a rational manner so that at least one person can operate the system, and in order to take full advantage of its mobility, it is easy to handle the mobile installation.

An example of implementing the present invention will be described below with reference to the drawings. As shown in FIG. 1, the main body 1 of the adjustment console according to the present invention is generally a rectangular parallelepiped with a mirror-slanted upper surface, and the front part of the upper surface is cut out to make it large enough to be easily transported, for example. , 130×
It is approximately 95 x 43 inches in size, and its lower half is housed in a box-shaped case 2. Casters 3 are attached to the lower surface of the case 2 for easy movement, and a cover 4 that covers the upper part of the main body 1 is removably provided on the upper surface of the case 2 via an engaging tool 5. The case 2 and cover 4 provide anti-vibration protection for the main body 1, and also facilitate handling when the main body 1 is moved or installed. Further, the cover 4 has a hanger 6 in its internal space for storing connection cables and the like at times of inconvenience. On the other hand, a total of four handles 7 are attached to the side surface of the main body 1 to facilitate handling when the main body 1 is pulled out from the case 2 and installed on the floor, etc., and the back side thereof has various handles 7, which will be described later. A connector board 8 for integrally connecting and distributing power to adjustment equipment and other electrical equipment is exposed from the case 2 and disposed so as not to be interfered with. In order to respond to the diversification of video program production, the present invention provides, as necessary and sufficient conditions, two television camera systems, two corresponding microphone systems, and recording and playback systems for the inputs of both systems. , it can be summarized as having the function of being able to switch and operate both systems as appropriate.

Here, housing two TV camera systems in the adjustment console main body 1 of the present invention increases the size and weight of the main body 1 and impairs its mobility. The system is designed so that a TV camera can be connected as needed when in use. Therefore, recesses 10 for stacking and fixing the camera control units 9 of both systems are appropriately recessed on the top surface of the main body 1, and connectors 11 for both units are provided on the upper part of the display panel, which will be described later. ing.
Additionally, inside the main body 1, there are two video tape recorders (VTR) 12 that receive and record signals from the two camera control units 9 mentioned above, and that enable recording by cutting and editing of the two systems. A synchronization generator 13, which generates an external synchronization signal for this purpose, has been reinstalled at an appropriate location. The adjustment system for freely switching between the two TV camera systems and the VTR and making editing adjustments includes a front display panel 14 in the front notch space of the main body 1 and a switch on the tabletop in front of the display panel 14. Everything is arranged on the panel 15 so that all the operations can be performed by at least one person.

FIG. 2 shows the arrangement of various devices on the display panel 14 (upper half) and switch panel 15 (lower half). In the figure, 16 receives signals from the two camera control units 9. It is a approximately 5-inch black and white monitor that displays the images currently being taken by both cameras, and is placed on the left side of the display panel 14. 17 and 18 are wave monitors and vector scopes that are arranged side by side in the center of the display panel 14, and 19 is a master color monitor, which displays images being edited or images recorded on the VTRs 12 and 12 after editing. It is used to playback and monitor the image quality such as the color tone of the video.

Due to its nature, this monitor 19 must be somewhat large. Therefore, in the present invention, in order to ensure mobility, the monitor 19 is not incorporated into the main body 1.
It was designed so that it could be connected as a separate body, and it could be remounted on the main body 1. 20' are playback switches for reproducing both VTRs, 21 is a tape counter that digitally displays the mirror image time, 22 is a reset button for the counter 21, and 23 is a counter 21 for the green image time of both VTRs. VTR counter select switches 24' and 24' and VTR recording and playback time selection switches 25 and 26 are speakers and audio level meters, which are arranged on the right side of the display panel 14.

27 is a power monitoring meter for the main body 1 itself; 28 is an oscillator and speaker selector switch for adjusting the audio level; 2
Reference numeral 9 denotes a power connector, which is provided on the side surface of the main body 1.

Further, in the switch panel 15, 30 is a group of video monitor switches, and 31 is a group of 2 mix switches, so that editing and adjustment can be performed even when one camera is added in addition to the two television cameras. 32 is a fader switch that produces video effects such as a state in which camera images are gradually removed or generated from the screen or superimposed images, 33 is a switch for adjusting the wipe effect of the video, and 34 is a wipe waveform. 35 is a switch for adjusting the type of line to be wiped, and 36 is a positioner.

In the present invention, the two mix switch groups 31 and the wipe effect switch group 33 are all arranged on the left side of the switch board 15, so that when the editing adjustment operator operates alone, he/she can perform the operations with only his/her left hand. We are taking this into account. 37,
38 is a group of camera remote control switches for adjusting the exposure and coloring of the two cameras, 39 is a group of control switches when one other combined force camera is attached, and the attached camera is installed on the back of main body 1. connected to a connected board, and monitored (not shown).
