    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.

  • Page 8: Typical Applications

    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;...

  • Page 9: Hot Switching

    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.

    2. Select an empty compartment. 3. Carefully place the DVP-101i between the module guides and slowly push the module towards the rear of the frame until the module's edge connector is secured to its rear module. A light pressure to mate the connectors may be required.

  • Page 12: Imaging Solo Housing Frame

    Connector labels have been shipped with your DVP-101i. Select the label according to your housing frame model. This label is to be installed on the housing frame's rear panel in order to identify the DVP-101i external connectors. To install the label, follow these steps.

    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).

    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.

  • Page 21: Black Level Adjustment

    –800 to +800, the default value being set at 0. Perform the following steps to adjust saturation: 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 SAT is displayed.

  • Page 22: Horizontal Picture

    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.

  • Page 23: Vertical Timing Delay

    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).

    9. To return to normal mode, press ESC. 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).

  • Page 25: Audio Embedding

    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).

    8. To return to normal mode, press ESC. 3.8 Freeze Functions The DVP-101i has a manual freeze pushbutton situated on the front edge of the module (see figure 3.1 Front Panel Interface) that allows a user to freeze (grab) a video image.

    To change the freeze mode follow these steps: 1. Press SELECT to enter the menu. PROC is displayed. 2. Press the “ + “ push-button until FRZE is displayed. 3. Press SELECT; MODE is displayed. 4. Press SELECT to enable the Freeze Mode menu. The current Freeze Mode selection is displayed.

  • Page 29: 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.

  • Page 30: Horizontal Blanking Setting

    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.

    3.9.3 Horizontal Blanking Setting For the composite analog output, the blanking interval can be set to narrow (as per SMPTE 259M : all pixels are passed) or wide (as per SMPTE-170M). To select the desired horizontal blanking setting, perform the following steps: 1.
