Keys 4 Chapter

Using four DME channels on one keyer

When using the DME dedicated interface, proceed as follows.

1 Select the DME channel 1 (or channel 5) for the first channel (see “Assigning a DME to a key” (page 401)). In the same way, select the DME channel 2 (channel 6) for the second channel, the DME channel 3 (channel

7)for the third channel, and the DME channel 4 (channel 8) for the fourth channel.

2 To select the video signal for the second channel, hold down the [UTIL] button in the cross-point control block, and select the signal in the Key1 row (DME external video bus).

3 To select the video signal for the third channel, hold down the [UTIL] button in the cross-point control block, and carry out the following operation.

If the selected DME is channel 3, turn off the [KEY4] button in the key 2 row, then select the signal in the key 2 row (DME utility 1 bus).

If the selected DME is channel 7, turn on the [KEY4] button in the key 2 row, then select the signal in the key 4 row (DME utility 2 bus).

4 To select the video signal for the fourth channel, hold down the [UTIL] button in the cross-point control block, and carry out the following operation.

If the selected DME is channel 4, turn on the [KEY4] button in the key 2 row, then select the signal in the key 4 row (DME utility 2 bus).

If the selected DME is channel 8, turn off the [KEY4] button in the key 2 row, then select the signal in the key 2 row (DME utility 1 bus).

When using the SDI interface

The operations to select the video signals for the third and fourth channels differ from those in the previous procedure: select the video signals on the AUX bus allocated in a Setup menu (Engineering Setup >Switcher >Device Interface >DME Type Setting >DME SDI Interface menu).

Note

In setup (Engineering Setup >Switcher >Device Interface menu), if “Up to 3Keys” is selected, the second channel video signal is also selected on the AUX bus.

For details, see “Interfacing With External Devices (Device Interface Menu)” in Chapter 16 (Volume 2).

You can check the DME operating status in the Status menu (see page 556).
