The Serial Digital Interface (SDI) is a professional protocol that allows you to achieve high quality results. The DVS board is a professional SDI capturing solution and it has a built-in RS-422 port that ensures the perfect interaction with the timecodes. Both capture and slave devices should be set to DVS.

Drivers Installation

  1. Download the DVS sdk/driver package from the Cinegy portal.

    Important
    Refer to the System Recommendations document for the list of the appropriate drivers.
  2. Unzip the downloaded package to any folder on a local drive (for instance, C:\DVS).

  3. Shut down your computer.

  4. Insert the DVS board to a proper PCI slot.

    Note
    The DVS board must be properly connected via RS-422 and SDI cables. Refer to your DVS board documentation to learn more about the board.
  5. Start your computer.

  6. The "Found New Hardware" wizard will appear with a question about software installation for "Centaurus II".

  7. Select the "Locate and install driver software" option. On the next step select to show more options. Then select "Browse my computer for driver software (advanced)". Browse for the "\driver" folder inside the unpacked DVS SDK package for the dvs.inf file (for instance, C:\DVS\driver\dvs.inf).

    Note
    If the "Windows can’t verify the publisher" dialog appears, select "Install this driver software anyway".
  8. To check the board settings and functionality, start dvsconf.exe from the \Bin\ folder of the DVS driver package. Select "Driver location" and specify the path to dvs.inf if it does not exist. Try to unload/load driver to check the driver availability.

Caution
To assure proper work with the DVS board, all the Cinegy modules such as Cinegy Ingest, outgest, playout, etc. should have access to the dvsoem.dll file. Check the DVS driver package that you have installed on your computer and add the path to the folder containing the dvsoem.dll file (also \Bin\). To do this, go to My Computer > Properties > Advanced > Environment Variables and edit the variable value for the "Path" variable.

SDI Ingest Dongle

You need to install the Cinegy USB hardware dongle with the Cinegy Ingest license on the machine in order to make SDI-based ingest possible.

Without the dongle, the message "Dongle not found" will be imprinted in the input SDI frames.

DVS SDI Setup

Select "DVS SDI" from the input device list.

SetupButton

Press the "Setup" button next to the hardware device; the following dialog box appears:

DVS_setup_scr

Settings in this dialog are split into configuration groups.

Video Mode

Define the target TV format by selecting the video format from the drop-down list.

Select the "SF mode" option to enable the segmented frames scanning for video images being ingested.

Audio Input

Define the audio input type from the drop-down list.

Timecode Correction

Choose a required timecode correction method for the DVS ingestor:

  • None – no processing, only the original timecodes are used.

  • Free run – gets just the first timecode and generates the rest by the frame counter.

  • TC handling by – the actual TC from the device. If a TC break occurs, the ingest session starts generating the free run TC; if the source TC recovers for more than set duration, it generates the TC break (a new "Entire") and continues with the actual timecodes till the next TC break.

Audio Channels

Select which stereo audio channels are to be included during ingest.

Live Ingest

Select the "Live ingest" option to activate this feature. Live ingest allows you to capture from live feeds or directly from video camera.

Note
The "Live ingest" option must be enabled in order to perform ingest via the Batch Ingest plan.

You can choose from the following timecode sources for your live ingest session:

  • PC clock

  • External audio TC

  • External RS-422

Signal Lost Tolerance

This feature allows you to save the SDI input failure during the live ingest.

Define the tolerance time in seconds. If the capturing mode is inactive and the tolerance time is exceeded with no signal, the following error message appears:

nf27_05_b

If the signal is lost during a live ingest, the following may occur:

  • immediate appearance of an alert indicating that the signal is lost;

  • interruption of the ingest process when the tolerance time is exceeded and the signal is not recovered; then another alert appears.

The system continues the ingest if the failure was shorter than the tolerance. If a signal failure occurs during a non-live ingest, the ingest session is stopped immediately:

nf27_05_c
Important
Refer to the Troubleshooting Ingest section if you are encountering problems with your DVS - SDI device.

VTR Configuration

Define the VTR type by choosing a required one from the drop-down list and enter the VTR preroll time in seconds. Then select the timecode type used for ingest from tape:

  • Auto – automatically switches between LTC and VITC;

  • LTC – uses the LTC (Linear Timecode) standard for ingest;

  • VITC – uses the VITC (Vertical Interval Timecode) standard for ingest.

Define the timecode source by selecting the required one from the "TC1 source" drop-down list. To use the additional timecode source, select the "Get TC2" checkbox and choose the second timecode source from the "TC2 source" drop-down list.

DVS Board Test Modes

The following options can be configured here:

  • Generate A/V flash every second – enables generation of the audio/video flash every second in this mode;

  • Superimpose S1 waveform – enables the S1 stereo audio waveform superimposing in this mode.
