XPT-38 Board (XVS-9000/XVS-8000/XVS-7000/XVS-6000)

The XPT-38 board has 290 x 290 serial matrix, out process, and multiviewer functions to switch signals and perform

output processing.

The XPT-38 board consists of the following blocks.

• Serial crosspoint circuit

• Color background circuit

• Multiviewer circuit

• Compare circuit

Serial crosspoint circuit

IN1 to IN160 (XVS-9000/XVS-8000), IN1 to IN112 (XVS-7000) and IN1 to IN64 (XVS-6000) input signals and the

internal reentry signal are input to the serial crosspoint circuit on the XPT-38 board, and are then sent to the M/E block,

output processor block, frame memory block, DME block, and format convertor block through the matrix.

Color background circuit

A color BKGD generator circuit for 4 channels (1 channel for 4K) is provided to output the generated Color BKGD

signal to the serial cross point circuit.

Multiviewer circuit

This circuit converts the SDI signal sent from the serial crosspoint circuit to a multiviewer output signal.

The multiviewer circuit can display the SDI signal selected arbitrarily in the cross point circuit on a screen split into

4/10/13/16.

XVS-9000/XVS-8000/XVS-7000/XVS-6000 contains two multiviewer circuits.
