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 imaging Quartet, Quartet-C or Quartet-M, imaging Solo or imaging

Symphonie housing frame for mounting and power.

1.3 Typical Applications

1.3.1 Audio Mux/Demux Applications

The DVP-101i is designed to work in conjunction with the DAP-711i/712i audio

processor; the DVP can extract embedded audio, pass it to the DAP module for

processing and re-embed the audio at the output. A delay tracking output allows the

audio processor to match the delay introduced by the DVP-101i. The figures below

show typical applications involving both the DVP-101i and DAP-711i/712i. Note that

only one audio group can be processed by a DAP-712i module; therefore, two DAP

modules may be used in conjunction with one DVP-101i, one per audio group.

Figure 1.2 AES is extracted on DVP-101i, processed on DAP-711i/712i and re-inserted

on DVP-101i.

1.3.2 Hot Switching

Some applications or studio setups may require the input 4:2:2 signal to the DVP-

101i be switched between two or more synchronous sources. Since these

synchronous sources are generally not in phase with respect to each other,

unpleasant visual effects may occur when switching from source A to a

different time position in source B. Also, some “break before make” switchers will

further deteriorate the 4:2:2 signal by producing a hit on the video signal.

Figure 1.5 illustrates a typical hot switch setup. For a smooth transfer to occur

when switching between two sources, set the FRZE-MODE to ERR (error on input

signal). Immediately after a switch is performed on the routing switcher, DVP-101i

will detect an input error thereby performing a freeze. The DVP-101i automatically

switches to the last errorless field or black. Once the transfer between the two

sources is complete and after two full errorless input frames, the freeze is

removed and normal mode is resumed.

Note: Operation is guaranteed if the time delay between the two sources is less

than 10 video lines.

Figure 2.5 Symphonie rear panel label installation

2.4 DVP-101i Electrical Installation

When connecting the DVP-101i to external equipment, make sure that all serial digital

connections are point-to-point. For instance, there must be a point-to-point connection

between a 4:2:2 OUT BNC and target equipment. If a T-connector is used to connect

other equipment, the maximum specified cable length is no longer valid.

Also, make sure that the cable lengths of the output serial digital cables are a

maximum 250m (850') each. Refer to Figure 2.7 and to the following descriptions for a

complete DVP-101i electrical installation.

4:2:2 IN - serial digital input

Connect a serial digital video signal, conforming to the SMPTE 259M-C standard to

the BNC labeled 4:2:2 IN. The DVP-101i will automatically switch to the detected line

format and turn on the corresponding LED on the module’s front end (figure 3.1).

Studio reference input with loop-through output

For external synchronization, connect the studio reference signal to the BNC labeled

REF IN. The DVP-101i accepts SMPTE 170M/PAL ITU 624-4 or 2 Vpp/4 Vpp compo-

site sync reference signals. When using the Quartet, Quartet-C, Solo or Symphonie-

R-C, the DVP-101i provides a loop through output of the studio reference signal.

Make sure to terminate this output with a 75 Ω terminator when it is not being used.

A valid analog composite reference signal will turn on the REF indicator located on the

module’s front end (figure 3.1). The reference signal must be NTSC for 60 Hz sources

and PAL for 50 Hz sources. If there exists a line format mismatch between the

reference input and the 4:2:2 input, the REF indicator flashes.

4:2:2 OUT 1 and 2 - serial digital video outputs

The DVP-101i provides 2 video output BNCs. These BNCs, labeled 4:2:2 OUT 1 and

2 provide the decoded video signal conforming to the SMPTE 259M-C standard.

Composite outputs

Composite signals are provided on the BNC connectors labeled COMPOSITE OUT 1

and 2. Output format is user-selectable, NTSC for 525-lines format operation or PAL

for 625-lines format operation.

Delay – video processing delay signal and GPI output

When using a Quartet-M or Symphonie-R-M, the DVP-101i provides a video

processing delay signal through an RJ-45 connector using RS-422A transport

standard. The video tracking delay is a signal that specifies the current processing

delay of the card. It indicates to an audio processor the amount of delay that must be

added in the audio path to compensate for the video processing delay and frame sync

function to avoid lip sync problems. Connector pinout is detailed on Figure 2.6. (When

using the DAP-711i/712i as audio processors, install the DAP module(s) in the same

housing frame as the DVP-101i and use the onboard audio bus connectors as shown

in section 2.1 Mechanical Installation.)

The DVP-101i also shorts the GPI output to ground when an automatic freeze is in

progress, and optionally when a freeze is detected on the incoming video.

The front panel push-buttons are used to navigate the menu of Figure 3.2. The

following describes the function of each push-button when navigating through the

menu.

+: Press “+” to move down in the menu or to increase the parameter

value. For example, if you are currently at TIMG-FRAM, pressing “+”

will scroll downwards through the selections VERT, HORZ and FINE.

Maintaining “+“ depressed during a value adjustment will increase the

parameter value at a faster rate.

: Press “–“ to move up in the menu or to decrease the parameter value.

For example, if you are currently at TIMG-HOR, pressing “–“ will scroll

upwards to the selection VERT and FRAM. Maintaining “–“ depressed

during a value adjustment will decrease the parameter value at a

faster rate.

SELECT: Changes to a menu parameter are stored immediately to non-volatile

memory. For example, in COMP-SETP, after the desired setup has

been chosen, press SELECT. The menu returns to SETP and the

new setup value is stored for the current format.

ESC: If ESC is pressed after making changes to a parameter, the

parameter is reset to the value it had prior to the change. For

example, after changing the Cb value, press ESC. The menu returns

to Cb and the previous Cb value is reloaded .

Automatic Exit From Menu After 1-Minute Interval

If the menu is currently being accessed and no push-button has been pressed for

1 minute, the DVP-101i automatically exits from the menu, thereby returning to

normal mode. At the same time, changes made to the current parameter will be

stored.

3.4 Digital ProcAmp Functions

These functions allow the adjustment of different parameters for both the analog

and digital video outputs. Y, Cb and Cr gains may be adjusted individually or

simultaneously; the black level, hue and saturation may also be controlled.

Additional controls are also provided for horizontal picture positioning and cable

equalization.

3.4.1 Y, Cb, Cr Gain Adjustments

Individual components of the video output may be adjusted by performing the

following steps. Each component has an absolute gain range of –800 of +800,

with unity gain (the default value) being set at 0. To change the value more

quickly, depress and hold the “+” or “–“ pushbutton.

1. Press SELECT to enter the menu. PROC is displayed..

2. Press SELECT to enter the ProcAmp menu. Y is displayed. To adjust the Cb

or Cr component press the “+” push-button until Cb or Cr is displayed.

3. Press SELECT to enable the selected gain menu. The current value is

displayed.

4. Use the “+” or “–“ push-button to set the required gain level for the selected

component. Press the “+“ and “–“ push-buttons simultaneously to set the

selected gain level to unity.

5. Press SELECT to store the new gain level for the selected component.

6. Press ESC to return to PROC.

7. To return to normal mode, press ESC.

3.4.2 Overall Gain Adjustment

The overall gain applies to the Y, Cb and Cr gains simultaneously. Note that

relative gain setting differences are maintained between the individual

components: as an example, if Y is set to 100, Cb to 50 and Cr to 0, an overall

gain adjustment of 10 will result in Y=110, Cb=60 and Cr=10. Values range from –

800 to +800, unity gain (the default value) being set at 0. Perform the following

steps to adjust overall gain:

1. Press SELECT to enter the menu. PROC is displayed..

2. Press SELECT to enter the ProcAmp menu. Y is displayed. Depress the “+”

push-button until ALL is displayed.

3. Press SELECT to enable the overall gain menu. The current value is

displayed.

4. Use the “+” or “–“ push-button to set the required overall gain. Press the “+ “

and “–“ push-buttons simultaneously to set the overall gain to unity.

5. Press SELECT to store the new overall gain.

6. Press ESC to return to PROC.

7. To return to normal mode, press ESC.

3.4.3 Saturation Adjustment

The saturation adjustment (chroma gain) affects both the Cb and Cr gains

simultaneously. Note that relative gain setting differences are maintained between

the Cb and Cr components: as an example, if Cb is set to 100 and Cr to 0, an

overall gain adjustment of 10 will result in Cb=110 and Cr=10. Values range from
