Widget Signal Routing

NTV2 device FPGA firmware implements several types of “widgets“ for receiving, processing and transmitting video data. These can be classified as follows:

• widget_inputs
• widget_outputs
• widget_processing
  • Dual-Link (DL) converters (input & output)
  • Two-sample-interleave (Tsi) muxers/demuxers
  • 4K Down-converters
  • DVC Pro converters
  • Universal Frequency Converters (UFCs)
• End-to-End (E-E) Routing
• Routing for Capture
• Routing for Playout
• End-to-End (E-E) Routing

Most widgets typically have one or more registers associated with them for reporting status, or to control their operation. Rather than calling CNTV2Card::ReadRegister or CNTV2Card::WriteRegister, client applications should use the appropriate widget-related API calls in the CNTV2Card class to inquire about and/or control the widget of interest.

Routing for Playout

This section shows how to programmatically set up a device for transmitting video for several commmon scenarios.

SD/HD YCbCr Playout From YCbCr Frame Buffer

//  Example:  Set up FrameStore3 for RGB playout, route to SDI 3...
theDevice.SetFrameBufferFormat (NTV2_CHANNEL3, NTV2_FBF_10BIT_YCBCR);
theDevice.SetMode (NTV2_CHANNEL3, NTV2_MODE_OUTPUT);
theDevice.Connect (NTV2_XptSDIOut3Input, NTV2_XptFrameBuffer3YUV);  // SDIOut3 <== FB3
 
//  Or, more generically...
NTV2Channel chan = NTV2_CHANNEL3;
NTV2FrameBufferFormat fbf = NTV2_FBF_10BIT_YCBCR;
theDevice.SetFrameBufferFormat (chan, fbf);
theDevice.SetMode (chan, NTV2_MODE_OUTPUT);
theDevice.Connect (::GetSDIOutputInputXpt(chan), ::GetFrameBufferOutputXptFromChannel(chan, NTV2_IS_FBF_RGB(fbf))); // SDIOut3 <== FB3

SD/HD YCbCr Playout From RGB Frame Buffer

//  Example:  Set up FrameStore3 for RGB playout, route to SDI 3...
theDevice.SetFrameBufferFormat (NTV2_CHANNEL3, NTV2_FBF_ARGB);
theDevice.SetMode (NTV2_CHANNEL3, NTV2_MODE_OUTPUT);
theDevice.Connect (NTV2_XptCSC3VidInput, NTV2_XptFrameBuffer3RGB);  // CSC3 <== FB3RGB
theDevice.Connect (NTV2_XptSDIOut3Input, NTV2_XptCSC3VidRGB);       // SDIOut3 <== CSC3RGB
 
//  Or, more generically...
NTV2Channel chan = NTV2_CHANNEL3;
NTV2FrameBufferFormat fbf = NTV2_FBF_ARGB;
theDevice.SetFrameBufferFormat (chan, fbf);
theDevice.SetMode (chan, NTV2_MODE_OUTPUT);
theDevice.Connect (::GetCSCInputXptFromChannel(chan), ::GetFrameBufferOutputXptFromChannel(chan, NTV2_IS_FBF_RGB(fbf))); // CSC3 <== FB3RGB
theDevice.Connect (::GetSDIOutputInputXpt(chan), ::GetCSCOutputXptFromChannel(chan)); // SDIOut3 <== CSC3RGB
