Multiview Output Layout
PGM and PVW as Preview and Program displayed as following image. The level meter of PGM audio is shown only in multiview. SDI/HDMI PGM out is without any overlays.
The following 6 windows come from the 6 input signals.
The lower right corner display of the menu and status information. The CH1, CH2 are the channel selection of the 2 audio sources for audio mixer. There is a real-time Digital clock/Analog clock displayed beside the menu.
PGM PVW Switching
PGM, PVW Channel Selection
Below 1-6 buttons from PGM and PVW are corresponding with the 6 windows in the below of the multiview layout. The selected button from PGM turns on to red LED, and the selected button from PVW turns on to green LED.
