Circuit Description
Sync system of Video signal processing system for DNW-75/75P
Reference internal signals for video and audio systems are produced on the VPR-47 board.
The inputted reference video signal from the REF VIDEO connector or the inputted video signal from the
analog video input connector (COMPOSITE or COMPONENT Y) is selected on the CP-334 board and
sent to the timing generation block on the VPR-47 board.
In the timing generation block, sync and burst signals are separated and extracted from the input video
signal.
Sync signals (HD, VD, and CF) are extracted from the SDI signal input to the SDI INPUT connector by
the SDI decode block on the SDI-41 board.
On the VPR-47 board, reference internal signals, timing signals (HD, VD, FRAME, CF, GOP, and
AUDIO ID), and clocks (for video and audio) synchronized with this reference signal are produced based
on the extracted sync signals. These signals and clocks are sent to each board.
The reference signal (SV REF) for a servo system is also produced by the timing generation block on the
VPR-47 board and sent to the SS-83 board.
Sync system of Video signal processing system for DNW-65/65P
Reference internal signals for video and audio systems are produced on the VPR-47 board.
The inputted reference video signal from the REF VIDEO connector is sent to the timing generation
block on the VPR-47 board.
In the timing generation block, sync and burst signals are separated and extracted from the inputted
reference video signal.
On the VPR-47 board, reference internal signals, timing signals (HD, VD, FRAME, CF, GOP, and
AUDIO ID), and clocks (for video and audio) synchronized with this reference signal are produced based
on the extracted sync signals. These signals and clocks are sent to each board.
The reference signal (SV REF) for a servo system is also produced by the timing generation block on the
VPR-47 board and sent to the SS-83 board.
