KEY AUTO: | This switch is used to set the key synthesis to ON or OFF. |
| When it is pressed, it lights, and key synthesis is performed for the text, etc. |
| KEY AUTO U is used to set the transition time for the key synthesis. When |
| the switch is pressed again, it goes off, and the input signals used for the |
| key synthesis will be synthesized as they are with the base image but, |
| depending on the level of the input signals, it may not be possible to |
| achieve clean and clear images. |
SOURCE: | This selects whether to use the VIDEO IN 5 signal or image in the frame |
| memory as the source material for the key synthesis. In terms of the key |
| signals, use black base level signals, and provide a source with white |
| characters. |
| A source with color characters can also be synthesized with a black base |
| but, depending on the level of the character signals, it may not be possible |
| to achieve clean and clear images. |
| (By inverting the polarity of the key signals, images with a white base level |
| can also be synthesized. For details on key reversal, refer to SETTING R.) |
Note
Follow the procedure below to keep the key synthesis on the PVW screen at the OFF setting at all times.
1.Press both the SETTING Button R and COLOR Button T at the same time.
2.With the two buttons in step 1 held down, press the KEY AUTO Button. The KEY AUTO Button lamp now lights.
To turn the key synthesis on the PVW screen back to the ON setting, repeat the same steps. The KEY AUTO Button lamp will then go off.
OIntercom Jack [INCOM]
Connect an intercom headset to this terminal. Use the recommended headset (made by Ashida Onkyo
PIntercom Volume [INCOM LEVEL]
To adjust the volume of the headset speaker connected to Intercom Jack O. Turning it counterclockwise decreases the volume, and turning it clockwise increases it.
{Genlock Phase Controls [GEN-LOCK PHASE]
Connect a signal generator or other such instrument to GLIN/BBOUT D, and use these
controls to adjust the phase when genlock is to be initiated. These controls need not be adjusted when genlock is not going to be initiated.
H:This is used to adjust the horizontal sync phase.
SC: This is used to adjust the subcarrier phase coarsely.
SC FINE: This is used to adjust the subcarrier phase finely.
Adjusting the horizontal phase:
Monitor the waveforms of the genlock signal (black burst signal) and video signal output using a
Adjusting the subcarrier phase:
Select the color bars of the switcher. Using the signal generator as a reference, adjust the SC Control and SC FINE Control to align the color phase. A more accurate adjustment can be achieved using a vectorscope.
}A-Bus Input Selection Switches
To select
qB-Bus Input Selection Switches
These are used to select the
Depending on the operation mode, the switches may light with full or half brightness. Full brightness: When the selected input is being output to PGM OUT.
Half brightness: When the switch is selected but the selected input is not being output to PGM OUT.
[Example] When the Fader Lever is at the
wFreeze indicator [FRZ]
This LED lights to indicates that the VIDEO IN 5 signal is frozen. Bear in mind that since the image remains frozen while it is lighted, the switcher output will not change even when the input signal has changed.
eInput 5/FMEM Selector Switch [FMEM]
This is used to select the signal which has been input to VIDEO IN 5 or the internal frame memory. When the switcher is used for the first time and the frame memory has been selected, the factory setting screen is output. By transferring image data from a personal computer to the frame memory, the images and text created by the user can be output. For details, refer to the page on which image transfer is described.
rBLACK/COLOR/BAR Selector Switch [BLACK/COLOR/BAR]
This is used to select BLACK (black level signal), COLOR (color background) or BAR (color bar). When COLOR is selected, one of nine colors can be selected. For details on how to select the color, refer to the section on “T Color Background Color Selector Switch [COLOR]”.
A 100% white signal is output at the factory setting.
