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.

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

10

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.

3.3 Menu Introduction

Most DVP-101i parameters are accessed and changed via an easy-to-use menu. The flow chart of Figure 3.2 outlines the entire DVP-101i menu path. The menu consists of 8 major functions: processing, timing, audio, ancillary data blaking, freeze mode, composite output controls, configurations, and factory reset. Each menu is described throughout this section. The following items should be remembered when accessing the menu.

Normal Mode The DVP-101i is in Normal Mode when the menu is not being accessed. Navigating Through the Menu 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

13

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.

3.5 Timing Adjustments

When the DVP-101i operates without a reference signal, it operates in Frame Delay/Frame Buffer mode: the timing adjustment sets the processing delay between the input signal and the output signal. However, when a valid reference signal is installed, the DVP-101i is in Frame Synchronizer mode: the timing adjustment sets the processing delay between the reference signal and the output signal. When the vertical and the horizontal timing is set to zero (0), the output is vertically and horizontally phased with the reference. Note that when the reference is not present and the DVP-101i is locked to the input, a zero phasing (vertical timing and horizontal timing set to 0) is not possible because of the minimum processing delay of the card.

Timing has several levels of adjustment which include vertical timing (video lines),

horizontal timing (µs), horizontal fine timing (no unit) and frame phasing (frames).

3.5.1 Frame Phasing Frame phasing allows a super coarse adjustment in frame increments, from 0 to 7

frames. When a reference is present (Frame Sync mode), the frame adjustment

18

allows additional frames to be added after/before the frame sync. As an example, a frame phasing of 4 will produce a delay between 4 and 5 frames.

When there is no reference and the phasing is done on the video, the frame phasing adjustment adds a delay in frame increments between the input and output video (Frame Delay/Frame Buffer mode). A zero phasing (H & V) is not possible because of the processing delay of the card.

To adjust frame phasing perform the steps below:

1. Press SELECT to enter the menu. PROC is displayed. 2. Depress the “+” push-button until TIMG is displayed. 3. Press SELECT to enter the Timing menu. FRAM is displayed. 4. Press SELECT to enable the frame phasing menu. The current value is

displayed. 5. Use the “+” or “–“ push-button to set the required frame phasing value. Press

the “+“ and “–“ push-buttons simultaneously to set frame phasing to default. 6. Press SELECT to store the new frame phasing value. 7. Press ESC to return to TIMG. 8. To return to normal mode, press ESC.

3.5.2 Vertical Timing Delay The vertical timing delay adjustment is made in increments of 1 video line up to

524 lines in 525-lines format and 624 lines in 625-lines format. Follow these steps in order to adjust vertical timing delay:

1. Press SELECT to enter the menu. PROC is displayed. 2. Depress the “+” push-button until TIMG is displayed. 3. Press SELECT to enter the Timing menu. FRAM is displayed. Depress “+”

until VERT is displayed. 4. Press SELECT to enable the vertical timing delay menu. The current timing

delay in video lines is displayed. 5. Use the “+” or “–“ push-button to set the required vertical timing delay. Press

the “+“ and “–“ push-buttons simultaneously to set vertical timing delay to 0 video lines.

6. Press SELECT to store the new vertical timing delay. 7. Press ESC to return to TIMG. 8. To return to normal mode, press ESC.

3.5.3 Horizontal Timing Delay The horizontal timing adjustment is made in increments of 37 ns up to a range of

one video line (63.5 µs in 525-lines format and 64.0 µs in 625-lines format). Follow these steps in order to adjust horizontal timing:

1. Press SELECT to enter the menu. PROC is displayed. 2. Press the “+“ push-button until TIMG is displayed. 3. Press SELECT to enable the timing menu. FRAM is displayed. 4. Press the “+” or “–“ push-button to display HORZ. 5. Press SELECT to enable the horizontal timing menu. The current timing delay

in µs is displayed. 6. Use the “+” or “–“ push-button to set the required horizontal timing delay.

3.6 Audio Functions

The DVP-101i can de-embed up to 2 audio groups from the ancillary data space of the video input, pass it to companion DAP-711i/712i Audio Processor modules and re-embed it at the output (see section 2.1 DVP-101i Mechanical Installation for details about DAP module installation). Each audio group travels to the audio processor using its own bus, called ABUS (audio bus); different parameters allow the audio functions to be configured for each of the 2 buses.

3.6.1 Audio De-Embedding

Up to 2 audio groups may be de-embedded (“demuxed”) from the input video signal; each of the ABUS may be assigned one of the audio groups. To select which audio group to de-embed, follow these steps:

1. Press SELECT to enter the menu. PROC is displayed. 2. Press the “ + “ push-button until ABUS is displayed. 3. Press SELECT; #1 is displayed. Press SELECT to choose ABUS #1 or press

“+” to display #2 and press SELECT. 4. Press SELECT; DMUX is displayed. Press SELECT to enable the audio de-

embedding menu. OFF or the currently selected audio group is displayed. 5. Use the “+” or “–“ push-button to choose the desired audio group to de-

embed. Press the “+“ and “–“ push-buttons simultaneously to set audio de-embedding to OFF.

6. Press SELECT to store the new audio de-embedding setting. DMUX is displayed.

7. Press ESC to return to ABUS. 8. To return to normal mode, press ESC.

20

Note: When no DAP audio module is used, the Audio De-Embedding function should be set to off for proper operation of the DVP-101i.

3.6.2 Audio Embedding

Up to 2 audio groups may be embedded (“muxed”) into the input video. Audio is obtained from the ABUS linked to the DAP modules. When an audio group is inserted in the ancillary data space, it overwrites the previous audio group (if present) in the video. As an example, when there are 4 groups of audio present in the video and a new group 2 is inserted, the previous group 2 is replaced by the new one. In a situation where there is too much ancillary data on a line, the new audio group is inserted first, then the existing ancillary data, until it runs out of available space. The rest of the data is ignored.

To select which audio group to embed, follow these steps:

1. Press SELECT to enter the menu. PROC is displayed. 2. Press the “+“ push-button until ABUS is displayed. 3. Press SELECT; #1 is displayed. Press SELECT to choose ABUS #1 or press

the “+” push-button to display #2 and press SELECT. 4. Press SELECT; DMUX is displayed. Press the “+“ push-button until MUX is

displayed. 5. Press SELECT to enable the audio embedding menu. OFF or the currently

selected audio group is displayed. 6. Use the “+” or “–“ push-button to choose the desired audio group to insert.

Press the “+“ and “–“ push-buttons simultaneously to set audio embedding to OFF.

7. Press SELECT to store the new audio embedding setting. MUX is displayed. 8. Press ESC to return to ABUS. 9. To return to normal mode, press ESC.

Note: When no DAP audio module is used, the Audio Embedding function should

be set to off for proper operation of the DVP-101i. 3.6.3 VBIT Setting

Upstream equipment usually sets the V bit in the audio stream when an audio error occurs. Because some audio equipment does not properly mute the audio when the V bit is set, the DVP-101i can be instructed to mute the audio for the duration of the V bit or to pass the audio as is. When Mute is selected, the DVP-101i will smoothly mute the audio signal, then resume passing the current audio when the V bit is cleared (see figure 3.3). To select a VBIT setting, follow these steps:

1. Press SELECT to enter the menu. PROC is displayed. 2. Press the “+“ push-button until ABUS is displayed. 3. Press SELECT; #1 is displayed. Press SELECT to choose ABUS #1 or press

the “+” push-button to display #2 and press SELECT. 4. Press SELECT; DMUX is displayed. Press the “+“ push-button until VBIT is

displayed. 5. Press SELECT to enable the VBIT selection menu. The current VBIT setting

is displayed. 6. Use the “+” or “–“ push-button to choose the desired VBIT selection. Press the

“+“ and “–“ push-buttons simultaneously to set VBIT selection to PASS (default setting).

BLAK (black) Displays a black frame at the output 3.8.3 Input Video Freeze Detection In addition to providing an automatic freeze on incoming signals with detected errors, the DVP-101i has the ability to detect that the incoming video itself is frozen. An alarm is raised once the frozen state has been detected for longer than a user-specified period. The alarm will be announced on the card itself (the card-edge ERR LED will illuminate and the display will show INFZ), on the rear-panel GPI output, and on iControl. This feature is very useful when the DVP-101i is processing video coming from a circuit prone to failure, such as an MPEG satellite receiver. When most receivers lose the satellite carrier, they freeze their output but do not send an alarm. A DVP-101i with Input Video Freeze Detect enabled will identify the frozen video and raise the alarm. To select the detection period, or turn the feature off, perform the following steps: 1. Press SELECT to enter the menu. PROC is displayed. 2. Press the “+“ push-button until INFZ is displayed. 3. Press SELECT to enable the Input Freeze menu. The current selection is

displayed (either OFF or a time interval in seconds). 4. Use the “+” or “–“ push-button to choose the desired status. Press the “+“ and

“–“ push-buttons simultaneously to set the status to 0FF (default setting). 5. Press SELECT to store the new status. INFZ is displayed. 6. To return to normal mode, press ESC.

3.9 Composite Output Settings

3.9.1 Setup Level The setup level for the composite output can be set to 0 IRE or 7.5 IRE, in NTSC

only. Thus this menu is only available when a valid NTSC input signal is used. To select the desired setup level, perform the following steps:

7. Press SELECT to enter the menu. PROC is displayed. 8. Press the “+“ push-button until COMP is displayed. 9. Press SELECT; SETP is displayed. 10. Press SELECT to enable the Setup Level menu. The current setup selection

3.9.2 Color Framing Control

25

It is possible, with the color framing adjustment, to set the desired subcarrier phase to horizontal reference point (SC/H) of the outputs with respect to the input reference signal.

Table 3.3 provides an example. Here, we describe the difference between a

NEAR and +1 color framing for NTSC outputs. Notice the vertical timing between the reference input and the analog output. In this example, there is a vertical delay of 1 field. If NEAR is selected, the output color framing (or burst locked sinewave) will follow the same subcarrier phase pattern, starting with field 1, as the reference input. That is, all analog output field 1 lines will have a positive going zero crossing of burst phase as all field 1 lines of the reference input, all output field 2 lines will have a negative going zero crossing of burst phase as all field 2 lines of the reference input, and so on.

On the other hand, if a color framing of +1 is selected, the subcarrier phase

relationships of fields 3 and 4 of the reference input is transferred to fields 1 and 2 of the analog output and the color framing continues as usual. That is, all analog output field 1 lines will have a negative going zero crossing of burst phase as all field 3 lines of the reference input, all output field 2 lines will have a positive going zero crossing of burst phase as all field 4 lines of the reference input, and so on.

For NTSC analog outputs, only NEAR and +1 selections are available to adjust

color framing. However, due to PAL’s 8 field color frame, the selections NEAR, +1, +2, and +3 are available.
