5.4.1. HD-SDI Dual Link to 3G-SDI (Level B) Conversion

To interface between a HD-SDI dual link receiver and 3G-SDI single link transmitter equipment, perform a HD-SDI dual link to 3G-SDI (level B) conversion. Level B is defined as 2× SMPTE ST 292 HD-SDI mapping, including SMPTE ST 372 dual link mapping.

Note: This feature is only available for Arria V, Cyclone V, and Stratix V devices. You can enable this feature through the SDI II parameter editor.

This conversion takes either two 1.485 Gbps dual link signals or two separate co-timed HD signals and combines them into a single 3G‑SDI stream.

Figure 25. Example of HD-SDI Dual Link to 3G-SDI (Level B) ConversionThe figure shows the conversion of two HD-SDI data streams to 3G-SDI (level B) data streams.


Figure 26. Implementation of HD-SDI Dual Link to 3G-SDI (Level B) ConversionThe figure shows a block diagram of HD-SDI dual link to 3G-SDI (level B) conversion.
