1 DVP-101i 4:2:2 Digital Video Processor/Synchronizer
1.1 Introduction
The DVP-101i is a high-quality processing amplifier providing control and adjustment
of a 4:2:2 digital video signal. This unit accepts a serial digital 4:2:2 signal conforming
to the SMPTE 259M standard. Adjustments include gain, setup and equalization
control of individual components and overall hue control. Timing adjustments include
individual component retiming, horizontal and vertical active video retiming, and video
signal retiming.
Embedded audio can be muxed or demuxed to/from the serial digital video and sent to
a Digital Audio Processor card (companion module DAP-711i/712i) using a special I/O
port.
Equipped with automatic 525- and 625-line format input detection, the DVP-101i
maintains all-digital, minimum 10-bit signal processing throughout the unit. This
structure ensures reliable and repeatable results. Error detection and handling (EDH)
is performed at the input and at the output. Vertical and horizontal ancillary data are
buffered through or blanked according to user selection. Vertical interval data is
buffered through, blanked or processed on a line-by-line basis according to user
selection. An internal color bar generator further enhances the DVP-101i’s
functionality. All outputs conform to the SMPTE 259M standard.
The easy-to-use microprocessor-based user interface simplifies user selections and
allows precise adjustments of the parameters. All DVP-101i adjustments and
selections can be controlled remotely with Miranda’s iControl software and RCP-100.
The DVP-101i is a member of the
imaging
family of digital video cards and therefore
requires the
